    摘要: A method provides navigation assistance to a user by tracking the user's position. By detecting similar features, the accuracy of the position measurement of the user is improved, making use of a priori frequencies that various feature types exist in the area. The method provides techniques for planning a route using the tracking information and is able to explore previously-untraveled paths in response to a setting in the search process. The navigation information can be saved or retrieved from a database so that users may share the data obtained during navigating an unfamiliar area.

    摘要: A control system enables a user to control an electronic device by moving parts of the face, including the eyes. Optical emitters and optical detectors are used to reflect light from the relevant parts of the user's face. Pattern matching or approximation of a pointing location are used to define the control input to the electronic device based on the user's motions. Visual feedback is optionally provided to the user during the controller's actions. Additional sensor elements are optionally provided to improve performance of the system. Hardware and software elements are combined to provide for the specified control actions.

    摘要: A system provides feedback to a user to guide the user to point a part of the body at a target of interest. An angle sensor senses the angle in which the part of the user's body is pointing, such as the head or the hand. The system computes the angle to a target and compares to the angle in which the part of the user's body is pointing and the feedback indicates to the user how to point more closely to the direction of the target. Additional sensors allow the system to update the angle to the target as the position of the user changes. A walking sensor is disclosed to accurately measure the position of the user.

    摘要: A system for rotating sound or selective listening to sound provides for the ability of the apparent direction of sound sources in a listening environment to remain in consistent orientations in space despite rotations of the microphones used to capture the sound and despite rotations of the head of the listener, even when wearing headphones. Modules are provided in the system to distinguish the sound sources and their apparent directions, as well as to optionally rotate the sound sources in response to detected rotations of the listener's head and/or detected rotations of the microphones.
