C++ Qt app for tracking eyes focus on screen by JAZZ-novo eye tracker device.
Version 0.2-alpha
You can compile program by Qt Creator with GCC (under Linux) or MSVC (under Windows) compiler.
Download it from http://www.ftdichip.com/Drivers/VCP.htm and install.
If you use Ubuntu (at least version 11.10 ) drivers are already in kernel. To automatically load appropriate driver when device is plugged in you have to:
- Create file
/etc/udev/rules.d/99-ftdi.rulesif it doesn't exist already - Add the following line to the file
ACTION=="add", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="e859", RUN+="/sbin/modprobe ftdi_sio" RUN+="/bin/sh -c 'echo 0403 e859 > /sys/bus/usb-serial/drivers/ftdi_sio/new_id'" - Run
sudo udevadm control --reloadin the console
If you don't have permission to use ttyUSB0 serial port you have to add your user to dialout group:
sudo usermod -aG dialout $USER
And reboot the system.
Firstly, calibrate device input by clicking Start calibration button and follow calibration procedure described below. If you go through calibration with success you can start new tracking session by clicking the New session button, but before you must enter needed information in configuration form.
Start calibration button allows you to enter calibration mode. In this mode application shows calibration board stretched to screen resolution. Calibration procedure is to follow your eyes markers starting from top left, then stop on each one and hit space key on your keyboard. Correct order of markers to focus your eyes on is as follows:
- Top left
- Center
- Bottom right
- Bottom left
- Center again
- Top right
You can exit this mode by hitting ESC key on keyboard.
Start new session button allows entering session mode where you can see red dot on screen in the position of your eyes focus if the calibration is successful. On screen there is also displayed your test board chosen in the configuration as background.
You can exit this mode by hitting ESC key on keyboard.
