CHANNEL WAVEGUIDE SYSTEM FOR SENSING TOUCH AND/OR GESTURE |
摘要 |
<p>This disclosure relates to a channel waveguide, at least a portion of which is disposed within a viewing area of an interactive display, proximate to and substantially parallel to a user interface surface of the interactive display. A source of a first electromagnetic or acoustic signal is input to the channel waveguide. At least one detector is configured to receive, from the channel waveguide, a second signal corresponding to the first signal and to output a third signal indicative of a position of an object proximate to the channel waveguide.</p> |
