After successfully finishing a calibration it fails to move the mouse or highlight any of the buttons.

It has worked well in the past.

Also when I switch into mouse control mode, the cursor is stuck in the upper left corner.

What do I need to do to fix it? What is going on?

Basically what is happening is the calibration is getting corrupted by a setting.

Why the Upper Left Corner

Somewhere in the calibration code a divide by zero is occurring, and it gets infinity, and wants to move the mouse to infinity. The position that the computer interprets as infinity is -2147483648 or something similar. On a screen with x,y coordinates, the upper left corner is 0,0. And -2147483648, -2147483648 turns into the upper left corner, too.

How to Fix It

Doing a hard reset of settings in Quick Glance fixes it. The fastest way to do this is to create a new user and delete the old one.

Go to:

The Grid 2 > User Settings > Input Settings > Eye Gaze > Calibration > Show Live View

This shows the Quick Glance window.

Then click:

Quick Glance > Settings > Users > Add

Then click on the old username, probably Default User, and then click Delete User.

Then to properly rehide Quick Glance, click Show Live View a second time in The Grid 2.

Click Calibration and it should perform a calibration in the Grid 2.

The calibration should work just fine and you are on your way.

Any custom eye tracking settings will be deleted when creating a new user. So be sure to go back and change any smoothing/stability settings or any eye processing settings if necessary. The Grid 2 normally manages these settings so you don't need to worry about it.

Quick Glance update

A new version of Quick Glance is coming that doesn't have this problem. It should be released soon. Updates about it will be posted here and on the main landing page for Quick Glance:
