摘要： Methods and systems for estimating a gaze direction of an individual using a trained neural network. Inputs to the neural network include a face image and an image of a visually significant eye in the face image. Feature representations are extracted for the face image and significant eye image and feature fusion is performed on the feature representations to generate a fused feature representation. The fused feature representation is input into a trained gaze estimator to output a gaze vector including gaze angles, the gaze vector representing a gaze direction. The disclosed network may enable gaze estimation performance on user devices typically having limited hardware and computational resources such as mobile devices.

摘要： Methods and systems for gaze assisted interaction with a pointing device on a display screen. In response to receiving an activation input, a user's point of gaze (POG) on a display is received and a gaze region of the display corresponding to the POG is extracted, enlarged and transposed on the display according to a first cursor location, generating an interaction region on the display. A user interaction with the pointing device at a second cursor location on the display associated with the interaction region is intercepted in a system hook, mapped to a location on the display corresponding to the gaze region and passed to an application. The disclosed method and system may enable improved GUI interaction with pointing devices on displays while overcoming challenges associated with the precision of eye-gaze assisted interaction, including the impact of eye jittering on gaze estimation.

摘要： Systems and methods for alerting a driver to a potential driving hazard are disclosed. Hazard parameters representing a driving hazard may be received. The driving hazard may have a corresponding Ground Truth Operation Sequence (GTOS) comprising an ordered sequence of GTOS Designated Meta Operations (DMOs). The corresponding GTOS may be retrieved and instantiated using the hazard parameters. Current driver operation parameters may then be received, and may then be mapped to a GTOS DMO of the ordered sequence of GTOS DMOs. Subsequent driver operation parameters may then be received, and may then be compared to a set of probable subsequent operations associated with the mapped GTOS DMO. It may then be determined that the subsequent driver operation is absent from the set of probable subsequent operations, and an output may be generated for alerting a driver to the driving hazard.

摘要： Methods and systems for preventing motion sickness via postural analysis are provided. In response to a determination that the portable electronic device is in motion, that the portable electronic device is being used for visual activities, and that the user of the portable electronic device has an unhealthy posture, a time to implement an intervention is determined. The intervention is subsequently performed at the determined time.
