The recording PC is a measuring system that is specified for real time gaze detection. It offers highest performance. The processor can read, process, save and display video and audio streams in real time. During processing, the pupil in the picture of the camera eye is detected and selected. That is realised through picture processing algorithms. The system writes the position and geometry data and the calibration configurations onto the hard drive. Synchronously it writes the audio and video data onto the hard drive. Parallel the system displays the present fixation position of the test person in real time. That allows you to track the test person’s gaze. For the recording processor you can choose between a laptop or a desktop PC. Technical data of the PCs:

Recording laptop:
