Three-dimensional user interface effect to the display by using the motion characteristics

摘要

PROBLEM TO BE SOLVED: To provide techniques that use a compass, MEMS accelerometer, GPS module and MEMS gyrometer to infer a frame of reference for a hand-held device.;SOLUTION: This provides a true Frenet frame, i.e., X- and Y-vectors for the display, and also a Z-vector that points perpendicularly to the display. In fact, with various inertial clues from accelerometer, gyrometer, and other instruments that report their states in real time, it is possible to track the Frenet frame of the device in real time to provide a continuous 3D frame of reference. Once this continuous frame of reference is known, the position of a user's eyes may either be inferred or calculated directly by using the device's front-facing camera. With the position of the user's eyes and a continuous 3D frame of reference for the display, more realistic virtual 3D depictions of objects on the device's display may be created and interacted with.;COPYRIGHT: (C)2014,JPO&INPIT
