US Classification:

34820799, 348144, 382103

Abstract:

According to one embodiment, the present invention relates to an integrated chip for detecting eye movement. An eye tracker device may include a CMOS image sensor which provides an imaging process of a user's eye image. The eye tracker device may be implemented on a single chip where pixel-level image processing is performed, thereby achieving high operating speed. A smart CMOS Image Sensor (CIS) pixel array may include a CMOS image sensor with a “shrink” function of locating a center of a pupil while eliminating influence of a black region around the eyebrow or pupil at the pixel level so as to accurately find the location at which a user views. The CIS pixel array may include an “expand” function of removing glint or other interference occurring in the pupil due to external light or other source.

Abstract:

The method and system are based on knowledge branch structure which is a hierarchical categorization of a subject's fundamental and complex elements and PAQ which is designed to re-test students on only those concepts which give an ambiguous outcome. Therefore, the method and system act as a formative and summative assessment in one which provides teachers and students with accurate and in-depth analysis of data as well as descriptive feedback from the test data. Many embodiments of the invention can be implemented as an assessment tool on a computing system, more specifically through program/software.
