iPal: a Visual-based Technology Platform

We have spent years tackling various technical challenges to make iPal a reality. With eye and gaze tracking, iPal can accurately and automatically see what your eyes see or what your eyes do. No other wearable camera or computer today knows what the eyes do (output) or can accurately measure what they eye sees (input). For instance, head tracking cameras with narrow field of view usually miss what the user pays attention to, while those with wide angle field of view always capture extraneous and irrelevant information.

iPal’s Enabling Technologies

iPal is powered by four patent pending technologies: eye tracking, gaze tracking, eye gesture coding, and optical imaging system.

Eye Tracking

iPal_Eye_Tracking1Eye tracking determines the location of the pupil and the angle of the eye’s optical axis. iPal tracks both eyes in real time using a patent pending ultra low-power eye tracking technology.

Gaze Tracking

Gaze tracking determines where your eyes are focused within the scene. In order to estimate the gaze point, iPal maps the angles of the eyes to the scene. iPal automatically calculates the gaze point and monitors for accuracy.

Eye Gesture Coding

iPal uses standard eye gestures such as left and right winks, blink,  double blinks and a number of other proprietary eye movements to control and operate the cameras. By using a combination of spatial and temporal movements, we have developed a large number of easy to use and intuitive commands. These features allow an iPal user to fully operate the device without lifting a finger or saying a word. (Of course, an iPal user can control the device from its touch screen or from a paired smartphone.)

Optical Imaging System

iPal has also a patent pending optical imaging system design that allows iPal to see in narrow and wide angle view, and anything in between. iPal can also zoom automatically. Additionally, iPal can capture higher resolution images beyond the native resolution of the image sensor it uses.
