tobii-eye-interface

Tobii eye interface is a software which maps your eye movements and blinks to move the cursor and send keystrokes or button presses

How it works

It uses tobii APIs to get the gaze coordinate and then create a virtual absolute device with libevdev and move the cursor to absolute positions on the screen. This is an alpha version of the project, so the emulation stops after 2min.

Dependencies

• tobii stream engine (to be taken from tobii website)
• setup script from github
• libevdev (make a link in your "include" dir: ~sudo ln -s usr/include/libevdev-1.0/libevdev usr/include/libevdev) i don't know why this is not done automatically

Run on Ubuntu

Unfortunately to my knowledge only an Ubutnu-based distro >= 18.04 can be used to run this software.

• execute the setup script reported in the dependencies
• One new app called tobii-config should now be on your application drawer
• build this project (CMakeLists.txt)
• You can find the executable (eye-interface) in the Build directory you choose
• Calibrate the eye-tracker using the new tobii-config app.
• Launch the eye-interface using elevated prviledges sudo ./eye-interface
