    摘要: A personal object or obstacle detector apparatus with enhanced stereo imaging capability includes a sonar system having dual receivers with field lobes positioned based on psychoacoustic considerations such as interaural intensity difference (IID) and interaural time difference (ITD). Receiver field pattern shapes and directions are selected to match the natural IID and ITD associated with human hearing. In one embodiment, dual receivers are used with a common transmitter while another embodiment utilizes two transmitter/receiver pairs with the transmitter and receiver collocated.

    摘要: An apparatus for displaying images comprising a display capable of displaying rendered imagery. The apparatus comprises a rangefinder coupled to the display which is capable of determining the distance from a viewer to the display. The apparatus further comprises a means for displaying an image upon the display, the image having a perspective such that the display is a projection plane of a perspective volume. A distance from the projection plane to a center of the projection is proportional to the distance from the display to the viewer, and the distance from the center of the projection to the projection plane is dynamically modifiable depending on the distance detected by the rangefinder. The display may be transparent so that a background scene may be visible with the rendered image superimposed upon it.
