How do I improve the accuracy when interacting with small buttons?

You can enhance user interaction in various applications by increasing the standard button size, facilitating more accurate targeting with gaze input.

To maximize comfort when using NUIA across various applications, we recommend enlarging the user interface elements. Many modern applications offer a "touch mode," designed to accommodate the broader touch area of fingers. This adjustment results in a more user-friendly experience than the typically smaller buttons found in standard mouse-driven interfaces.

Microsoft Office (Outlook, Excel, Word, PowerPoint)

To activate touch mode in Microsoft Office applications, you only need to enable it once, and it will apply across all other Office applications such as Outlook or Excel. Here’s how to do it using Microsoft Word:

  1. Open Microsoft Word.
  2. Click on the search area. This is located at the top of the application.
  3. Enter “Touch Mode” into the search field. This will bring up the mouse/touch mode option.
  4. Select the touch input option.


This adjustment will slightly alter the layout of Outlook, so it is recommended to only keep this setting if you are fine with the gaze optimized layout.

Microsoft Edge

  1. Open Microsoft Edge.
  2. Open the Edge settings.
  3. Enter "Touch" in the search field.
  4. Scroll down in the search results and look for the setting "Touch mode". Change the setting to "Enabled."
  5. Restart Edge to make all changes effective.

Google Chrome

  1. Open Google Chrome.
  2. Enter in the address bar: chrome://flags (this opens additional, hidden settings).
  3. Enter "Touch" in the search field.
  4. Look for the setting "Touch UI Layout" and change the setting to "Enabled."
  5. Restart Chrome to make all changes effective.
