Suggested December 2023 Visualizing A Modern Apple Wireless Keyboard
Over the weekend, we learned some preliminary details about Apple’s planned updates for two of their most popular Mac accessories, the Apple Wireless Keyboard and Magic Mouse, in the form of FCC filings. Aside from new and improved connectivity thanks to Bluetooth 4.2, both accessories appear to have design deviations from their existing models, as detailed by the rough sketches accompanying the FCC filings. Based on these sketches, I decided to more fully visualize the changes Apple could be planning for an all new and more modern wireless keyboard based on other modern Apple product designs.
Long Time Coming
The Apple Wireless Keyboard as we know it today is a dinosaur in terms of technology products. It was first introduced alongside its larger, wired counterpart way back in 2007, not long after the first iPhone debuted, and the iPod, now removed, still reigned supreme in the navigation on chúng tôi In 2009, the wireless model was updated slightly to use one less battery, and a smaller wired keyboard was introduced. In 2011, two function keys received updated graphics to coincide with UI changes in the then new Mac OS X Lion. Aside from those tweaks, everything about the keyboard has remained the same for 8 long years. It’s safe to say that a refreshed design is in order. Let’s take a look at what’s changed since then.
Macs no longer ship with optical disc drives. Yet every wireless keyboard still ships with an eject button in the upper right corner of the keyboard. This is no longer useful on newer Macs as software can control occasional uses with external SuperDrives, and makes absolutely no sense when paired with an iPad, another popular use of the keyboard.
With the Apple Watch, Apple introduced the font San Francisco, an all new, custom typeface that has been making its way across the product lines, most recently as the keycap font for the new MacBook and coming soon Mac and iOS devices with iOS 9 and OS X El Capitan. The Apple Wireless Keyboard and MacBook Pro still use the older VAG Rounded font.Finally, along with the 12″ MacBook came the butterfly mechanism, an improvement to both the stability and space efficiency of individual key caps. This allows each individual key to be 40% thinner and 17% larger than on previous Apple keyboards. Naturally, this change should trickle down to the wireless keyboard.
The FCC filing sketch for the new Apple keyboard appears to show a design that ditches the cylindrical AA battery compartment on the rear of the device, in favor of a flat, low profile design with four rubber feet, and a small power button on the top edge. While the final design could deviate from the drawing, this change would make sense. The flat profile would imply improved typing ergonomics similar to MacBooks, reducing upward bending of the wrist. Ditching the AA battery power source in favor of a rechargeable, internal battery could also play into Apple’s continued efforts towards environmental conservation, reducing the need for disposable batteries, and perhaps finally allowing the abandoned Apple Battery Charger to retire.
Apple’s new found love for the Silver, Space Gray, and Gold trifecta of colors has permeated to almost all of their products, from the new MacBook, to Beats headphones, to the iPhone, iPad, and Apple Watch, all the way down to Apple gift cards. This new, colorful world would only be truly complete with keyboards to match. With an increased number of wireless keyboards being used with iOS devices, it would be fantastic to have matching finishes available across the line. Both white keys like are currently found on Apple’s keyboard and black caps like the ones found on MacBooks would work well, but Apple would likely choose one or the other. iOS devices in both silver and gold typically use white as their accent color.

This story has been updated. It was originally published on August 13, 2023.
There are dozens of ways to wirelessly share files, from attaching them to an email to uploading them to social media. But not all of your options are equally secure. In fact, to keep prying eyes away from your data, we recommend you send your files through a direct device-to-device connection.
Your phone and computer both come equipped with wireless transfer protocols that let you share files securely, sometimes without even revealing your phone number or email address. Each operating system—iOS, macOS, Android, and Windows—offers its own method, and once you know how each one works, you’ll be able to pick the best option for the devices you have.How to share files on iOS and macOS
Your iPhone, iPad, and Apple computer can all connect directly to other Apple devices via AirDrop. This type of link enables Apple devices to send files to each other, relying on Bluetooth to establish the connection and WiFi to handle the data transfer. A key note: For AirDrop to function, you must enable both Bluetooth and WiFi, but you don’t need to connect to an actual WiFi network.
This method of sharing is anonymous, which means you can send a file without knowing the recipient’s email address or phone number—and without disclosing your own contact information to them. The downside is that it only works when you’re sending a file between two Apple devices, so you can’t use it on Windows or Android.
[Related: Make your Apple and Android devices work together]
This works for photos, webpages, documents, and plenty more. Before accessing the file, though, the recipient needs to approve the share. This is important because some people abuse the anonymity we mentioned earlier, using it to send obscene or obnoxious files to strangers. To prevent this from happening to you, either refuse to accept files when you don’t know the recipient, or make sure to set your AirDrop discovery to Contacts Only.
What if you want to send a file to a friend’s Android or Windows device? When you hit that Share button, you can pick a different option—such as an email or a file-syncing app like Dropbox—from the pop-up menu. However, these file-sharing methods require that you have the recipient’s contact information and that your phone or computer is connected to the internet.How to share files on Android
Android has had several AirDrop-like options through the years, and the latest is called Nearby Share. Find it on devices running Android 6 or later by entering Settings, then navigating to Google, Devices & sharing, and Nearby Share. It should be on by default, but you can also enable it manually. Once it’s on, you’ll see Nearby Share as an option whenever you tap the Share button on your device (on Android, this button looks like a “less-than” sign).
To set who can share files with you, select Device visibility from the Nearby Share menu. The options are Everyone, which means anyone around you with an Android device will be able to send you a transfer invitation. But don’t worry—your phone won’t download anything without you agreeing to it first. The second option available is Contacts, which limits the people who can send you files to the names on your contacts list. You can turn on the toggle switch next to All contacts so you’re visible to everyone in your address book, or you can turn it off to choose the names of the people you want to be visible to one by one. Lastly, you can opt to be Hidden, which means your device will only be visible while Nearby Share is actually open.
For Nearby Share to work, both the sender and recipient must enable Nearby Share, and hold their devices close together. The option to either Accept or Decline the share is always available to the recipient, so Android will never force you to receive anything you don’t want or expect.
[Related: How to easily share anything from your phone]
Google says Nearby Share uses the best available protocol for file transfers, choosing from Bluetooth, Bluetooth Low Energy, WebRTC, or peer-to-peer WiFi. That way, the devices don’t have to be online for the transfer to work, as they are moving the files directly, point to point, without relying on another network.
When you tap that Share button in Android, other options will present themselves too. One of these is Bluetooth, which can transfer data quickly, device to device, potentially even if they’re several hundred feet apart. If you can’t use Nearby Share for whatever reason, Bluetooth is a useful alternative.
To enable Bluetooth, enter Android Settings, go to Connected devices, and toggle Bluetooth on. You can also swipe down from the top of the screen to open the quick settings menu and then tap Bluetooth. Once it’s enabled, the Bluetooth icon will appear any time you want to share something. Tap it, and Android will list any nearby Bluetooth-enabled devices—both Android and Windows—to which you can send that website or file. The receiving device may have to confirm the pairing action, but after that, the file will transfer easily.
As on iOS, there are a variety of other apps ready and willing to help you get a file from one phone to another. These probably include Gmail, Google Drive, OneDrive, Twitter, and Dropbox, depending on what you have installed on your phone. Using these apps won’t send files directly between devices though, and you’ll need to be connected to WiFi or a cellular network for them to work.How to share files on Windows
For Windows devices, direct transfers are best done over a Bluetooth connection. Although you can share Windows data over Bluetooth with Windows and Android devices, Apple machines won’t accept a Bluetooth file transfer. If you want to make a Windows-to-Windows connection, you can use Near Share, which works much like Apple’s AirDrop.
While a direct device-to-device transfer protocol that works between Apple, Microsoft, and Google devices would be welcome, it doesn’t look as though something like that will appear anytime soon. In the meantime, the best method for you depends on which devices and platforms are involved.
Mail clients are becoming a big deal in the App Store. Only a few weeks ago, Orchestra launched their popular
Mail clients are becoming a big deal in the App Store. Only a few weeks ago, Orchestra launched their popular Mailbox app to much fanfare. Before this, Twitter clients were trending, before that, RSS readers. Mail clients are likely to be the next wave of iOS apps for the months ahead.
Evomail is another mail client for the iPad to recently hit the App Store. This Gmail-specific app lets users access, organize, and respond to their mail in a way that incorporates Gmail’s interactions with Apple’s native Mail app…Design
As mail clients go, this one looks great. It has a classic design with clean features. It definitely has a modern business-like feel to it. The app can be used in portrait or landscape mode and looks about the same in either view. You just have more layers in portrait mode.
The app shows your email accounts at the far left of the screen, with your profile picture in a button at the top corner. The next section shows the inbox of the account you currently have selected. If you tap the three vertical lines at the top of the inbox, you will be able to see the email folders for that account.
To the far right is the actual email. When you have multiple emails in a single thread, all prior messages are listed in chronological order below the most current one.
Emails are created the same way they would be in Apple’s Mail app. When you enter the name of a person into the address line, a list of contacts will appear. To add an image, tap the attachment icon on the subject line.
The inbox, account folders, and messages are all displayed at the same time so that you can access any section without having to “tap back” to a different screen.App Use
The first thing you will need to do is log into your Gmail account. You can have multiple accounts attached to Evomail, but at the moment, they must be Gmail accounts. The developers are promising other service support in the future. Once logged in, you will see your accounts listed on the right side of the app. The number of unread messages will be listed next to the account name.
Select one of your accounts to see your mail’s inbox. When you select the account, a new section will appear to the right that shows all mail in that account’s inbox. You can see your account’s different folders by tapping the icon in the section’s upper-left corner.
The folders will appear in a new section to the left of the inbox. Your labeled folders will have colored dots next to them.
You can label new mail in the inbox by tapping the label icon at the bottom of the screen. Once labeled, you can archive the mail by tapping the check mark icon right next to the label icon. To delete a currently selected mail item, tap the “x.”
You can also move, archive, or delete groups of mail by selecting the “Edit” tab in the inbox section. You can then select any number of messages and then move them to a specific folder, archive them, or delete them all at once.
To respond to an email, tap one of the arrows at the bottom of the message. Like Apple’s Mail app, you can respond to the sender, reply to all, or forward to a new recipient. You can also respond to an email by swiping to the left from the current message. A response mail window will appear.
To start a new email, tap the create mail icon at the bottom left of the screen. You iPad’s contacts will automatically appear when you start typing into the address line. You can add images from your photo app, but you can’t attach documents.The Good
This email client looks good and runs smoothly. I love being able to label messages and redirect them to their appropriate folder. I also like being able to see all messages in an email thread instead of only the most recent ones. Being able to see your account’s inbox, folders, and current message all on one screen is a very efficient use of the iPad’s screen.The Bad
There are still some bugs to work out. On more than one occasion, I was unable to send an email. I’d tap the “Send” button and nothing would happen. When I closed the app in the multitasking bar and reopened it, it worked properly.
I also had trouble receiving email notifications. I only received two notifications in the two days that I used the app. One of the notifications came hours after the email was sent to me.
There is also no way to see the tutorial again after the first time. I wanted to know how to save an email address to my contacts, but wasn’t able to figure it out. The starting tutorial may have shown that, but I don’t remember and couldn’t find it in the app.
I also noticed a couple of bugs with the number of unread mail messages. Finally, I’d like to be able to join multiple account inboxes into a single inbox.Value
This email client costs $2.99. You are getting a fairly useful app for the price. However, because it is still in the early stages of existence, there are a few features that are missing and a lot of bugs to work out. If this were a free email client, I’d say it is a great bargain. However, for the three-dollar price tag, I wish it had launched with less bugs and more features.Conclusion
Evomail is a great starting point for what will hopefully become an outstanding app. It looks fantastic, but has a couple of rough edges. First impressions are very important. Evomail is like a young go-getter entering the workforce who shows up to an interview wearing a really nice suit, but sports some ratty sneakers that smell bad. You will definitely give him a chance, but you hope he does something about those shoes.
[UPDATE: Evomail is now optimized for the iPhone and iPad and is also compatible with Yahoo, iCloud, and IMAP servers.]
Logitech is one of the leading brands in the keyboard industry. The company is known for its high-quality and reliable products.
They offer various keyboards, from ergonomic keyboards to ultra-slim models. They also offer a variety of features, such as backlit keys, media controls, and programmable keys.
Logitech keyboards have a long-lasting battery life and are compatible with many different types of computers.
But are Logitech keyboards compatible with Mac?
Yes, all Logitech keyboards are fully compatible with Mac, with some models (labeled “for Mac”) being ready to work with macOS straight away. However, you will need to make one or two minor adjustments in macOS system preference if you use a Windows Logitech keyboard on Mac.
This guide will show you how to use a Logitech keyboard with Mac. We will also discuss what type of Logitech keyboards are compatible with Mac and how to set up your Logitech keyboard with Mac.
Logitech MX Mechanical Mini for Mac
Yes, you can use any Logitech keyboard (both mechanical and membrane) with a Mac. However, you should note that Logitech keyboards (and most mechanical keyboards) are Windows keyboards by default.
Below are some differences between Windows and Mac keyboards and computers.
The Modifier keys on Windows and Mac are similar in that they modify the behavior of other keys. However, the specific keys used for the modifiers are different.
On Windows, the Modifier keys are the Ctrl, Alt, and Windows keys, whereas, on Mac, the Modifier keys are the Command (⌘), Option, and Control keys.
The Command key is the closest equivalent to the Windows key, while the Option key is a close equivalent to the Alt key.
The Control key is a single key on both systems. They are also in a different order on a Mac than on a Windows keyboard.
Logitech’s keycap comes labeled with a Windows logo and does not show the Command logo as you would find in a Mac keyboard. However, the keycaps labeling does not affect the functionality of the key.
A Mac keyboard may have some additional features absent from a Windows Logitech keyboard. Some of these features include:
Command (⌘) Key: Mac keyboards have a dedicated Command key that provides quick access to keyboard shortcuts.
Option (⌥) Key: The Option key is used to access alternative character sets and menu commands.
Launch Pad: Launchpad is Apple’s application launcher for Mac OS X. It is designed to allow easy access to all the applications installed on your Mac.
Mission Control: Mission Control is a feature of MacOS that allows you to view and manage your open applications and windows. It provides an overview of all open windows and applications and lets you quickly switch between them or create new virtual desktops to organize your workflow.
Siri: Siri is a virtual assistant that helps you interact with your Mac more naturally. You can use Siri to search for files, launch apps, send emails, check the weather, set reminders, and more.
Some Windows Logitech keyboard keys also do not work on Mac off the box. Therefore you have to program some keys and assign them specific functions. Some of these keys include Scroll Lock, and Pause Break, among others.
Some Windows Logitech keyboards may not have 100 % functionality on Mac. You can apply some twerks to map your Windows keyboard to work seamlessly on Mac.
You should apply these modifications to Windows Logitech keyboards since “for Mac” Logitech keyboards are already mapped out to work with Mac.
Below are the steps you should follow to map out your Windows keys:
Plug your Logitech keyboard into your Mac.
Open Keyboard, which you will find under System Preferences.
Under the dropdown menu on Modifier Keys, switch the Option and Command keys. Doing so will rearrange your modifier keys in the correct order for a Mac.
Congratulations, you have remapped your Windows keyboard, which is now fully functional on your Mac.
Yes, most Logitech customization software is compatible with Mac operating systems. Some of these software include:
Although the Logitech software is not necessary to make the keyboard work on your Mac, installing the software will enhance your user experience.
Follow these steps to install the keyboard software on Mac:
Visit the Logitech Download Page.
Look for the software you want to download depending on your specific keyboard.
Follow the onscreen prompts on the installation process.
If you are experiencing problems with your Logitech keyboard when using it on Mac, there are several troubleshooting steps you can take to try and resolve the issue. Some of these steps include:
Usually, you will see a popup assistant requesting you to determine the keyboard’s layout by pressing a few keys. However, you can start from scratch by deleting your keyboard preferences files.
Follow these steps to do so:
Disconnect the keyboard from your Mac.
Tap the Library folder and then tap the Preference folder.
Drag the file named com.apple.keyboardtype.plist into trash.
Empty your trash.
Reconnect your keyboard using a USB cable.
The Logitech keyboard works with Mac. It also has several features that make it an excellent choice for Mac users, including customizable hotkeys, comfortable keys, and media controls. Furthermore, it is easy to set up and use, making it an excellent choice for anyone looking for a reliable, easy-to-use keyboard for their Mac. However, you may have to twerk your Logitech keyboard to get it working perfectly with your Mac. You can also download Logitech software on Mac to make the process easier and to get the best out of your Logitech keyboard.
Yes, “Mac-ready” Logitech keyboards are compatible with Mac operating systems. Logitech offers various keyboards designed specifically for Mac computers, such as the Logitech K380 Multi-Device Bluetooth Keyboard, Logitech Wireless Solar Keyboard K750, and the Logitech Wireless Keyboard K360.
These keyboards are designed to be compatible with Mac operating systems, such as macOS, OS X, and iOS. They are designed to provide easy access to all Mac-specific functions and features, such as the Command and Option keys and the contextual menus and shortcuts.
Yes, Windows Logitech keyboards are compatible with Mac. Logitech has a range of keyboards compatible with Mac and Windows operating systems. However, you may need to map some keys to function on Mac. Additionally, Windows Logitech keyboards come with a Windows logo instead of a Command key. You can plug in the keyboard to your Mac, and it will be ready to use once you make the simple modifications.
In addition, Logitech also creates keyboards with specific Mac compatibility features. These keyboards have specific keys and shortcuts that are optimized for macOS. Most Logitech keyboards compatible with Mac will also feature a Mac-specific key layout, allowing you to access essential features and shortcuts quickly.
Yes, Logitech gaming keyboards can be used with Mac computers. Logitech offers various gaming keyboards specifically designed for Mac, including the Logitech G915 Lightspeed, Logitech G513 Carbon, and Logitech G513 RGB. The keyboards are compatible with Mac operating systems such as macOS Mojave, High Sierra, and macOS Sierra.
In addition to the gaming keyboards, Logitech also offers a range of other keyboards that are compatible with Mac, such as the Logitech K380 Multi-Device Bluetooth Keyboard and the Logitech MK270 Wireless Keyboard and Mouse Combo. These keyboards are designed to work with Mac computers, so you should easily find one that suits your needs.
No, Logitech keyboards do not need software to work on Mac. All Logitech keyboards are plug-and-play, meaning you can connect them directly to a Mac computer without additional software or drivers. Once connected, the macOS should immediately recognize the keyboard.
Some Logitech keyboards support Bluetooth connectivity and can be connected to your Mac wirelessly.

OpenCV is the most popular library for the task of computer vision, it is a cross-platform open-source library for machine learning, image processing, etc. using which real-time computer vision applications are developed.
CVzone is a computer vision package, where it uses OpenCV and Media s its core that makes us easy to run like hand tracking, face detection, facial landmark detection, pose estimation, etc., and also image processing and other computer vision-related applications. Check here for more information.Implementation of Virtual Keyboard Using OpenCV
Let us create a virtual Keyboard.
First, let us install the required modules.
Import Libraries for Virtual Keyboard Using OpenCV
Now let’s import the required modulesimport cv2 import cvzone from cvzone.HandTrackingModule import HandDetector from time import sleep import numpy as np from pynput.keyboard import Controller
Here we are importing the HandDetector module from cvzone.HandTrackingModule and then in order to make the virtual keyboard work we need to import Controller from pynput.keyboard.cap = cv2.VideoCapture(0, cv2.CAP_DSHOW) cap.set(3, 1280) cap.set(4, 720)
Now let’s take real-time input from cv2.Videocapturedetector = HandDetector(detectionCon=0.8) keyboard_keys = [["Q", "W", "E", "R", "T", "Y", "U", "I", "O", "P"], ["A", "S", "D", "F", "G", "H", "J", "K", "L", ";"], ["Z", "X", "C", "V", "B", "N", "M", ",", ".", "/"]] final_text = ""
We initialize HandDetector with detection confidence of 0.8 and assign it to the detector. Then we create an array of lists according to the layout of our keyboard and define an empty string to store the typed keys.Defining Draw Function keyboard = Controller() def draw(img, buttonList): for button in buttonList: x, y = button.pos w, h = button.size cvzone.cornerRect(img, (button.pos, button.pos, button.size,button.size), 20 ,rt=0) cv2.rectangle(img, chúng tôi (int(x + w), int(y + h)), (255, 144, 30), cv2.FILLED) cv2.putText(img, button.text, (x + 20, y + 65), cv2.FONT_HERSHEY_PLAIN, 4, (0, 0, 0), 4) return img
Initialize the keyboard controller, and define a function with name draw() and it takes two arguments that is an image and the buttonList and return the image. Here Inside the draw() function, we are using cvzone’s cornerRect function to draw rectangle edges at the corner of each keys. It is in order to make our keyboard layout look better. It will look something like the below images.
You can also try changing different colours.class Button(): def __init__(self, pos, text, size=[85, 85]): chúng tôi = pos chúng tôi = size chúng tôi = text
Then we define a class called Button() and we give position, text and size as the inputs so that we can arrange the keyboard keys in a well-defined order.buttonList =  # mybutton = Button([100, 100], "Q") for k in range(len(keyboard_keys)): for x, key in enumerate(keyboard_keys[k]): buttonList.append(Button([100 * x + 25, 100 * k + 50], key))
The above loop will loop through the keyboard keys and Button objects where we give position and text as inputs are appended in a list called button list. Later we can pass this list to draw function to draw on top of our real-time frame.Main Program for Virtual Keyboard Using OpenCV
Here comes the important part.while True: success, img = cap.read() img = detector.findHands(img) lmList, bboxInfo = detector.findPosition(img) img = draw(img, buttonList) # change the draw funtion to transparent_layout for transparent keys if lmList: for button in buttonList: x, y = button.pos w, h = button.size if x < lmList<x+w and y < lmList < y+h: cv2.rectangle(img, chúng tôi (x + w, y + h), (0, 255, 255), cv2.FILLED) cv2.putText(img, button.text, (x + 20, y + 65), cv2.FONT_HERSHEY_PLAIN, 4, (0, 0, 0), 4) l, _, _ = detector.findDistance(8,12, img, draw=False) print(l) if l < 25: keyboard.press(button.text) cv2.rectangle(img, chúng tôi (x + w, y + h), (0, 255, 0), cv2.FILLED) cv2.putText(img, button.text, (x + 20, y + 65), cv2.FONT_HERSHEY_PLAIN, 4, (0, 0, 0), 4) final_text += button.text sleep(0.20) cv2.rectangle(img, (25,350), (700, 450), (255, 255, 255), cv2.FILLED) cv2.putText(img, final_text, (60, 425), cv2.FONT_HERSHEY_PLAIN, 4, (0, 0, 0), 4) # cv2.rectangle(img, (100,100), (200,200), # (100, 255, 0), cv2.FILLED) # cv2.putText(img, 'Q', (120,180), cv2.FONT_HERSHEY_PLAIN, 5, # (0, 0, 0), 5) # img = mybutton.draw(img) cv2.imshow("output", img) cv2.waitKey(1)
Inside the while loop the main function takes place, first we read the real-time input frames and store it in a variable called img. Then we pass that image to the detector.findHands() in order to find the hand in the frame. Then in that image, we need to find the position and bounding box information of that detected hand.
Here we can find the distance between the top point of our index finger and middle finger, if the distance between the two is less than a certain threshold, then we can type the letter on which we are indicating. Once we get the position then we loop through the entire position list. From that list, we find button position and button size and then we plot it on the frame according to a well-defined manner.
Image 1: Hand Landmark Model
After that, we need to find the distance between the top point of our index finger and middle finger. In the above image, you can see the top points which we require are point 8 and point 12. Hence we need to pass 8, 12 inside a distance finding function in order to get the distance between them. In the above code you can see detector.findDistance() and there we passed 8, 12, and image in order to find the distance and we set the draw flag to false so that we do not need any line between the two points.
If the distance between the points is very less we will use press() function to press the keys. In the above code keyboard.press() and we are passing button.text in order to display that pressed key. And finally, we draw a small white rectangular box just below our keyboard layout in order to display the pressed key.
Once you execute the whole code it looks something like this.
After you bring the index finger and middle finger close to each other on top of a particular letter, you can type that letter.
If you need the keyboard layout to be more customized, we can make the keyboard layout transparent. We just need to add a transparent layout function and replace the draw() function with transparent_layout() function.
Let us define the transparent_layout() function. Below is the function, it takes the same input as that of the draw() function. Here we assign a numpy’s zero_like() function to a variable called imgNew and perform the desired operation on that, like having the corner rectangle, creating the rectangle box for each key, and putting the text inside the box. After that, we copy that image to a new variable and create a mask of imgNew and we use OpenCV’s addWeighted() function to place the mask on top of the actual image. Hence this makes the keyboard layout to be transparent.Customizing the Keyboard def transparent_layout(img, buttonList): imgNew = np.zeros_like(img, np.uint8) for button in buttonList: x, y = button.pos cvzone.cornerRect(imgNew, (button.pos, button.pos, button.size,button.size), 20 ,rt=0) cv2.rectangle(imgNew, chúng tôi (x + button.size, y + button.size), (255, 144, 30), cv2.FILLED) cv2.putText(imgNew, button.text, (x + 20, y + 65), cv2.FONT_HERSHEY_PLAIN, 4, (0, 0, 0), 4)

Once you replace the draw() function inside while loop with transparent_layout() function it will look like this. (below image)Entire Code for Virtual Keyboard Using OpenCV

Fortunately, this cleaning process is not actually that hard to do. Think of it like a thorough dental cleaning, but for your computer, and stop being that person with the messy workstation. Take charge of your life and start with a fresh, clean keyboard.First, shut down your machine
It’s always best to disconnect your keyboard before you start the disinfecting process. Nobody wants liquid cleaning products near their hard drive when the computer is on. With a laptop, that means turning the entire machine off. If you have a desktop computer, you can just unplug the keyboard from your computer.Shake out your less-than-clean keyboard
With a good grip, stand over a garbage can and carefully turn your laptop or keyboard completely upside down. Then, gently shake your device so any dried-up crumbs or pieces of food will fall out, thanks to the handy force of gravity. This debris removal is an important early step because it gets the big, bulky stuff out so it won’t get in the way of your more precise scrubbing later on.

Just like any piece of furniture that sits in one place for a long time, the spaces between your keys and other keyboard components are going to gather dust. These particles, combined with any minuscule food crumbs, are nearly impossible to remove with gentle shaking alone. That’s where compressed air comes in. Compressed air, which is exactly what its name implies, comes in a can and can be purchased at any office supply store, superstore, and online. These cans are fairly cheap, but are a crucial, powerful tool for anyone trying to clean a keyboard—they can blast dust out of that random corner you didn’t even know you had.
When using compressed air, Apple recommends tilting your keyboard at a 75-degree angle so it’s nearly vertical, but not quite. Spray the compressed air into the keyboard and rotate the keyboard or laptop 90 degrees four times so the air hits as many areas of the board from as many angles as possible.Get scrubbing

Now that you’ve gotten all the dust and debris out, you can focus on those grimy, perhaps slimy, keys. Yes, it’s that time. For this, you’ll need a cotton ball, some Q-tips or another brand of cotton swab (they’re best used for cleaning, not sticking in your ears), and some basic isopropyl alcohol, also known as rubbing alcohol. You can buy all of these items at most pharmacies and grocery stores.
First, dab a small amount of alcohol onto the cotton ball and carefully clean each key. Then, for inter-key cleaning, switch to the Q-tip with a bit of alcohol. The small size of the cotton swab helps ensure the alcohol only goes onto the keyboard surface, not into it. Just be careful not to put too much alcohol on the Q-tip.
From experience, for extra scummy keys, you will need to scrub pretty hard. You may even have to go back to some keys for a second scrub.
The alcohol will likely get rid of most bacteria and germs that may have gathered on your keyboard. But if you want to be extra sure, you can finish with a multi-purpose cleaning wipe as well. Alcohol, because of its low boiling point, evaporates very quickly, which is another reason it’s so useful for cleaning keyboards—the area will dry within a few seconds.Consider removing the keys themselves
Usually, the combination of shaking, spraying, and scrubbing is good enough. But if your keys are sticking or you’re convinced there’s still some dirt under the keycaps, you can sometimes remove them. This technique depends on the type of keyboard you have and how it was put together. It’s helpful to have an electronics repair toolkit if you are going to attempt to remove them.Remember to clean your keyboard more often
Frequency is key. Just like brushing and flossing your teeth, the more often you clean your keyboard, the less likely it is that dirt and scum will have a chance to build up. While once a day is probably excessive, once a week is easily doable.The bacteria is probably not that bad—for you at least
Even if you never clean your keyboard, the bacteria that build up are probably normal, friendly bacteria—the same kind that gather on your phone and other items you touch every day. And you likely won’t get any new diseases from your own keyboard. But an unclean keyboard is an easy way to spread disease-causing bacteria, especially if you are sick and other people are using the device as well. A good cleaning once a week will limit the risk.
