Hi!

Could you please explain what do you need it for?

[AlexHevc]

I would like to improve it for my needs.

Hi!

The problem is that Tobii SDK license specifically prohibits recording or broadcasting gaze data in any form. So unfortunately we can’t share the source code. But we would love to hear any suggestions on how to improve the software.

Hi Alex,

I am using Eye tracker 4C. Not for games but to help me with coding.

The device precision is amazing.

This is what i would like to accomplish:

Use CapsLock key as trigger. On key-down capture gaze region of desktop and magnify 2-4 times. On Key-down capture gaze coordinate and translate from magnified image to desktop coordinates and issue mouse-click event on that location.

Ideally on key-down device should start tracking and on key-up it should turn-off(same as tray on/off switch).

Can you help me get started on coding this solution?

Thanks,
Alex

Hi!

You don’t need Streaming Gaze Overlay source code for that. I would start by looking at our Tobii Core SDK samples that show how to get gaze point from the device:

Hi Alex,

Any example of capturing keyboard shortcuts ?

Any example of transparent overlay ?

Thanks,
Alex

Hi!

Here are some hints:

Keyboard:
WinAPI RegisterHotKey
Or DirectInput

Transparent overlay:
Layered windows for transparency
DX11 for rendering
