Dynamic range resetting

Abstract

A system and method of determining that a movement of an eye, head or body part, as is captured in a series of images, is a movement intended to activate a function, by defining ranges within which the movement is deemed as not intended for function activation, and beyond which the movement is deemed as intended for function activation. The ranges may be adjusted dynamically to account for shifts in a resting position of the eye, head or body part.
