Input devices

In this article Identify the input devices connected to a Windows app device and identify their capabilities and attributes. Important APIs: Windows.Devices.Input, Windows.UI.Input, Windows.UI.Xaml.Input Retrieve mouse properties The Windows.Devices.Input namespace contains the MouseCapabilities class used to retrieve the properties exposed by one or more connected mice. Just create a new MouseCapabilities object and get the properties you're interested in. Note The values returned by the properties discussed here are based on all detected mice: Boolean properties return non-zero if at least one mouse supports a specific capability, and numeric properties return the maximum value exposed by any one mouse. The following code uses a series of TextBlock elements to display the individual mouse properties and values. private void GetMouseProperties() Related articles Samples • • • Archive samples •

Unless the data source is a type of electronic sensor that checks the environment and automatically sends relevant data to the computer, the human-computer interface (HCI) most likely uses one of the following devices to enter data into the computer. Device Category Typical Peripherals Input devices • Keyboard • Mouse • Scanner • Digital Camera • Web Camera • PC Video Camera • Microphone • Sylus Pen • Touch Screen Monitor Within the above list of typical input devices, you will find a wide variety of configurations and choices. We will look at just one of these here—the keyboard—but much of the same information applies to deciding which mouse device to use. PC Keyboards: How to Decide Which Keyboard Is Best for You Ergonomics is the study of designing equipment or tools to help users work comfortably and reduce strains on the body that can cause injury, such as carpal tunnel syndrome. Carpal tunnel syndrome is a painful condition affecting the hands and wrists, usually associated with repetit...

Note If you've had to sign your signature for a credit card purchase, you've likely used a stylus to sign your name. What is the difference between passive and active styluses? A stylus can come in two forms: passive (also known as a capacitive stylus) or active (also known as an active stylus or active pen). A passive stylus is not different than using your finger as far as the device is concerned. An active stylus (such as the one used with the palm rejection. How is a stylus an input device? Before the touch screens we know today, the stylus was used to input data into small palmtop devices. This form of input may be known as pen input. For example, the Today, a stylus is still considered an input device because it can point to and open or manipulate objects on a screen, like a computer What is a digital pen? A stylus is a small basic plastic or steel device that is only used to input data. A digital pen resembles a stylus but is bigger and has its own capabilities. For example, a digital pen may have a digital eraser that allows the pen to be flipped over and used as an eraser when drawing. Digital pens are also pressure-sensitive, allowing you to draw or paint on the screen depending on how hard you're pressing down on the pen. Other features may be one or more

Computer Input Devices This activity will give you the chance to consider the various computer input devices you learned about in the lesson and determine which devices are appropriate for the scenarios described below. For each scenario assume that there are no input devices attached to the computer. Describe all of the input devices that will be needed, using the list below, and explain why you chose each device and what its contribution is to the scenario. In some instances, there may be more than one correct answer, so explain which one you would prefer and why. Input Devices • Keyboard • Mouse • Microphone • Game controller • Webcam • Scanner • Printer • Headphones • Speakers Scenarios 1. Barbara wants to upload some pictures into an online scrapbook, adding text and laying out the images in a cohesive design. Which input devices will she need? 2. Billy wants to play an online game with his friends. They like to chat while playing in order to better communicate as they work together. His parents insist that he choose the quietest method possible as they're watching a show in the same room. Which devices will he need? 3. Becky has a major school report due tomorrow, which she plans to keyboard and hand in to her teacher. Which devices does she need? Discussion and Solutions 1. Barbara will need a scanner to scan the pictures for her scrapbook as well as a keyboard and mouse to add captions to the images and design her book. 2. Billy will need a keyboard and mouse at th...

It allows the input of raw data to the computer for processing. Here’s a list of some input devices used in computers and other computing devices: • Keyboard – one of the primary input devices used to input data and commands. It has function keys, control keys, arrow keys, keypad and the keyboard itself with the letters, numbers and commands. Keyboards are connected to the computer through USB or Bluetooth. A laptop keyboard is more compact than a desktop keyboard to make the laptop smaller and lighter. Smartphones and tablets use on-screen keyboard to input...

Great question. When you press a key, your keyboard sends a particular "scancode" to the computer. The scancode represents the key that was pressed. Here's an example of scancodes sent by IBM keyboards: The scan code is then interpreted by programs running on the computer (like the keyboard "driver"), and the pressed key information becomes available to the other programs running. If a program wants the computer to store the pressed key in memory, it will often store characters using the "ASCII" encoding standard. You can see the codes for that here: Uppercase "B" is 01000010, so that's what the computer would store in memory. At my house, I have a small color sensor for a lego toy. When I turn it on, it emits a beam of light and reads what the color is that it’s above. I’m trying to figure out if it’s an input or output device. 1. It has an on switch - input 2. It emits a light beam - output 3. It reads colors - input 4. It tells what color it’s reading - output It looks to me as if it’s a combination of the two. Are instruments such as this better categorized as their own computer as they have input and output? This is a really great question! You're right that it has both input and output qualities. Although when determining if something is mainly an input or output device, it's best to think of it in relation to a computer. If the device's main purpose is to gather information for the computer, then it's an input device. If its main purpose is to let the computer commu...
