Abstract: A method and system for time-motion compensation for use with head mounted displays is disclosed. According to the method, a remote camera captures an image for display on a head-mounted display (HMD) including a viewing window. The image and camera position data is transmitted to a system including the HMD for display to a wearer of the HMD. The HMD position is determined. An offset between the HMD position and a known position of the HMD is determined as is an offset between the camera position and a known position of the camera. The image is offset relative to the viewing window of the image based on the difference between the two determined offsets.

Abstract: An audio caller identification unit is connected between a user's telephone and a telephone exchange providing calling party identification, such as calling number or name. The unit has user accessible audio inputs, either a microphone or an interface to a handset of the telephone. The unit also has audio message memory, a user programmable table of concordance for tacking the location of audio messages, a record/playback device, a speaker, and a controller. The unit may also have a visual display. Control keys may be connected to the controller, however their function may also be performed by using a keypad of the telephone. A speech generator may also be connected to the controller and to the speaker. In operation, the unit has programming, review, and monitoring modes.
