Patent Images
1. A method comprising:
- generating a plurality of light beams from sources spaced from each other in a defined relationship;
imposing a user object within an area of the light generated in the generating step;
sensing light reflected from the user object;
correlating the light sensed in the sensing step with a predefined operation of a user device.

Abstract
A plurality of light sources is mounted on a housing of an interactive user device. The sources are spaced from each other in a defined spatial relationship, for example in a linear configuration. At least one light sensor is also positioned at the surface of the housing. The light sensor senses light that is reflected from an object placed by the user, such as the user'"'"'s finger, within an area of the light generated by the light sources. A processor in the user device can recognize the sensed reflected light as a user input command correlated with a predefined operation and respond accordingly to implement the operation.

13. Apparatus comprising:
-
an interactive user device embodied in a housing, the interactive device comprising a processor, a display, and a memory; a plurality of light sources spaced from each other at an outer surface of the housing; and at least one light sensor positioned at the surface of the housing; wherein the at least one light sensor is configured to input data to the processor data that correspond to sensed light generated by any of the light sources and reflected by an imposed user object, and the processor is configured to correlate the input data with a predefined operation of the user device. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
