Windows has two features to help you use the computer without using a mouse or keyboard: Speech Recognition (you can use voice commands to work with Windows) and On-Screen Keyboard (you can enter text by selecting characters on the screen).
You can turn on or adjust settings for these features on the Use the computer without a mouse or keyboard page in the Ease of Access Center.
Open the Use the computer without a mouse or keyboard page by clicking the Start button , clicking Control Panel, clicking Ease of Access, clicking Ease of Access Center, and then clicking Use the computer without a mouse or keyboard.
Select the options that you want to use:
Use On-Screen Keyboard. This option sets On-Screen Keyboard to run when you log on to Windows. On-Screen Keyboard displays a visual keyboard with all the standard keys. You can select keys using the mouse or another pointing device, or you can use keys on the standard keyboard. For more information about using On-Screen Keyboard, see Type without using the keyboard (On-Screen Keyboard).
Use Speech Recognition. Use this option to control the computer with your voice. With a microphone, you can speak commands that the computer will understand and respond to, as well as dictate text. For more information about setting up Speech Recognition, see Set up Speech Recognition.
