The Precision Gaze Mouse works as a standard HID device (USB or Bluetooth). It can be combined with:

A standard mouse moves instantly. A gaze mouse must filter out physiological noise. High-end systems use Kalman filters or predictive smoothing to differentiate between an intentional move and a twitch.

These systems typically consist of:

The best value for "precision." It has a 240Hz sampling rate (most are 60Hz), meaning it refreshes the cursor position four times faster than competitors, leading to virtually zero lag. Price: ~$1,200

A Precision Gaze Mouse is a type of assistive technology that uses eye-tracking software to detect and interpret the user's gaze, allowing them to control the cursor on a computer screen. This technology has been designed to provide people with disabilities, such as paralysis, cerebral palsy, or amyotrophic lateral sclerosis (ALS), with greater autonomy and independence when interacting with digital devices.
