A cognitive assessment system includes a computing device, a server coupled to the computing device and an eye tracking device coupled to the computing device. The computing device includes a cognitive assessment program with at least one cognitive assessment task for assessing at least one cognitive function of a user. The server includes a database. The database stores a historical task performance data of the user, a historical task performance model of the user, task performance data of a healthy population, and task performance data of a patient population. The eye tracking device is for capturing the eye movement data of the user.

Cognitive assessment system based on eye movement

Correction method and device for an eye-tracker are provided. A non-predetermined scene frame is provided and analyzed to obtain a salient feature information, which is in-turn used to correct an eye-tracking operation. The correction can be done at the initial or during the wearing of an eye-tracker.

Correcting method and device for eye-tracking

A digital adjustable chip oscillator comprises a voltage control oscillator, a reference voltage circuit, a voltage regulation circuit, a digital tuning circuit, a frequency detector and a programmable controller. The oscillator generates an oscillation signal and receives a control voltage and an operating voltage from the voltage regulation circuit and the reference voltage circuit to stabilize and adjust the frequency of oscillation signal. The digital tuning circuit receives a digital code stored in a programmable memory to adjust the control voltage. The frequency detector detects and compares the frequency of oscillation signal with a first and second frequency, wherein when the frequency of the oscillation signal lies between the first and second frequency, the frequency detector outputs a high voltage signal and otherwise the frequency detector outputs a low voltage signal. The programmable controller receives the high voltage signal to stop a programmable counter to acquire the digital code.
