Abstract: A system and method are provided for object tracking in a scene over time. The method comprises obtaining tracking data from a tracking device, the tracking data comprising information associated with at least one point of interest being tracked; obtaining position data from a scene information provider, the scene being associated with a plurality of targets, the position data corresponding to targets in the scene; applying a probabilistic graphical model to the tracking data and the target data to predict a target of interest associated with an entity being tracked; and performing at least one of: using the target of interest to determine a refined point of interest; and outputting at least one of the refined point of interest and the target of interest.

Abstract: A method is provided for estimating the orientation of a user's eyes in a scene in a system-agnostic manner. The method approximates pose-invariant, user-independent feature vectors by transforming the input coordinate to a pose-invariant coordinate and then normalizing the data considering the statistical distributions of previously collected data used to create a learned mapping method. It then uses the learned mapping method to estimate the orientation of the user's eyes in the pose invariant coordinate system, and finalizes by transforming these to a world coordinate system.

Abstract: A system and methods are provided to manage gestures and positional data from a pointing device, considering an attention sensing device with known accuracy characteristics. The method uses the state of the user's attention and the pointing device data as input, mapping them against predefined regions on the device's screen(s). It then uses both the mapping results and raw inputs to affect the device, such as sending instructions or moving the pointing cursor.

Abstract: A system and an apparatus are provided, for gaze tracking within a defined operating range. The apparatus includes at least one optical system, which capable of capturing radiation in a wavelength range produced by a composite illumination source. The apparatus also includes at least one set of illumination sources creating the composite illumination source, wherein: at least one of the illumination sources is positioned relative to the optical system such that it ensures a user bright pupil response at the beginning of the apparatus operating range; and the composite illumination source size is such that it creates a Purkinje image on a user's eye capable of being distinguished by the optical system at the end of the apparatus operating range. The apparatus also includes an illumination controller for activating and deactivating the at least one composite illumination source, and a signal processing controller for transmitting generated images from the at least one optical system.
