Input apparatus and methods having diffuse and specular tracking modes |
摘要 |
Input apparatus and methods are described. An object is illuminated with output light. Diffuse reflections of the output light from the object are captured. Diffuse reflection optical data is produced from the captured diffuse reflections. Specular reflections of the output light from the object are captured. Specular reflection optical data is produced from the captured specular reflections. A first set of motion measures indicative of movement in relation to the object is produced from the diffuse reflection optical data. A second set of motion measures indicative of movement in relation to the object is produced from the specular reflection optical data.
