Here are some accessibility options to help persons of different abilities use a Windows PC:

1) for persons with physical disabilities

2) for persons with low vision

3) for persons with blindness

4) for persons who are deaf or hard of hearing

Resources with more information on accessibility support for Windows can be found in Section 5.


1) For Persons with Physical Disabilities

a) Windows Speech Recognition with MouseGrid

Windows Speech Recognition

Windows Speech Recognition is a free-to-use app that allows users to control their PCs via voice command without the use of a keyboard or mouse. It is useful for persons with physical disabilities who have limited mobility in their upper limbs. Watch this video to learn how to set up and use the app. 


  • Windows PC with Windows 10

  • Windows Speech Recognition app installed and activated in ‘Listening’ mode


  • Check and adjust your microphone/headset levels in ‘Manage Audio Devices’ setting

  • Work in a quiet environment to give clear voice commands

  • Work best when operated on a single monitor screen

 Click here for a list of all the Windows Speech Recognition commands.


MouseGrid is a feature that comes with the Windows Speech Recognition app. It allows users to move the mouse pointer to a specific area with voice commands. After MouseGrid is launched, it will display a translucent three-by-three grid on the screen, with the sections divided and numbered.

Launching and Using the MouseGrid

  • Say “Open MouseGrid” or “MouseGrid” to open MouseGrid in full-screen

  • Say “Open Small MouseGrid” to open a small grid centered around the pointer's current location


  • Say one of the grid numbers (any number between 1 and 9) to select and zoom in on a specified section of the grid

Selecting Section 

When the section of the grid has landed on a defined part of the screen that users would like to access such as a button icon, say “Click” together with one of the grid numbers to select it (e.g. “Click 8”)

Dismissing the MouseGrid

  • Say Cancel” to remove MouseGrid

Below is an example of how MouseGrid is used alongside Zoom (video conferencing platform), to open the Zoom chat window.

When MouseGrid is activated on the screen, users can verbally command their preferred number shown on the grids on screen (for example, grid 8). A new three-by-three grid will appear in that area as shown below.

Users can repeat this process to get the grid to further define the area they wanted to click upon.


For a demonstration of how you can use voice control with MouseGrid to hold a Zoom meeting, watch this video.

The above method of using voice control with MouseGrid via Windows Speech Recognition can also be applied to other video conferencing platforms in Windows, e.g. Microsoft Teams, Skype for Business, Cisco Webex.
