Abstract
The present invention is directed to a visual mobility assist device which provides a conformal, augmented display to assist a moving body. When the moving body is a motor vehicle, for instance (although it can be substantially any other body), the present invention assists the driver in either lane keeping or collision avoidance, or both. The system can display objects such as lane boundaries, targets, other navigational and guidance elements or objects, or a variety of other indicators, in proper perspective, to assist the driver.

25. A mobility assist device, comprising:
-
a location system providing a location signal indicative of a location of a mobile body;
a data storage system storing object information indicative of objects located in a plurality of locations;
a display system; and
a controller coupled to the location system, the data storage system and the display system, and configured to receive the location signal and retrieve object information based on the location signal and provide a display signal to the display system such that the display system displays objects in substantially a correct perspective of an observer located at the location of the mobile body. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)

39. A method of monitoring operation of a mobility assist device having a location system providing a location signal indicative of a location of a mobile body, a data storage system storing object information indicative of objects located in a plurality of locations, a display system, a ranging system detecting a location of objects and transitory objects relative to the mobile body and providing an object detection signal based thereon, and a controller coupled to the location system, the data storage system, the ranging system and the display system, and configured to receive the location signal and the object detection signal and retrieve object information based on the location signal and provide a display signal to the display system such that the display system displays objects and transitory objects in substantially a correct perspective of an observer located at the location of the mobile body, the method comprising:
-
receiving the object detection signal;
determining whether the object detection signal correlates to the object information in the data storage system; and
providing an output at least indicative of a system problem when the object detection signal and the object information are determined not to correlate. - View Dependent Claims (40, 41, 42, 43)

44. A method of controlling a mobility assist device having a location system providing a location signal indicative of a location of a mobile body, a data storage system storing object information indicative of objects located in a plurality of locations, a display system, a ranging system detecting a location of objects and transitory objects relative to the mobile body and providing an object detection signal based thereon, and a controller coupled to the location system, the data storage system, the ranging system and the display system, and comprising:
-
receiving the location signal and the object detection signal;
retrieving object information based on the location signal; and
providing a filtered display signal to the display system, the display signal being filtered such that the display system displays objects and transitory objects, based on operator selected filtering criteria, in substantially a correct perspective of an observer located at the location of the mobile body.

45. A mobility assist device, comprising:
-
a location system providing a location signal indicative of a location of a mobile body;
a data storage system storing object information indicative of objects located in a plurality of locations;
a neurostimulation system; and
a controller coupled to the location system, the data storage system and the neurostimulation system, and configured to receive the location signal and retrieve object information based on the location signal and provide a stimulation signal to the neurostimulation system. - View Dependent Claims (46, 47)
