Method and apparatus for improved handset multi-tasking, including pattern recognition and augmentation of camera images
View Patent ↗This invention provides a handset ( 10 ) and a method of operating a handset. The handset includes a user interface that contains a data entry device ( 20 ) and a visual display device ( 14 ), a camera ( 16 ) and a controller ( 12 ) coupled to the visual display device and to the camera.
