High speed on-chip eye image data analysis is crucial for getting reliable results.
Processing the images taken by the eye tracker's camera on the computer's CPU, would create unpredictable results, because the CPU load can go up while playing computer games or using other demanding software applications. In such cases the computer would not have enough time to precisely analyze each image coming from the tracker. With the VT3 mini eye tracker the eye images are processed in high speed on the tracker itself and thus, independently of the used computer's power.
