Three-dimensional hand tracking using depth sequences

In the field of human-computer interaction (hci), i.e., the study of the interfaces between people (i.e., users) and computers, understanding the intentions and desires of how the user wishes to interact with the computer is a very important problem. The ability to understand human gestures, and, in particular, hand gestures, as they relate to hci, is a very important aspect in understanding the intentions and desires of the user in a wide variety of applications.

Optical differential solar tracking system

A system and method of using differential optical signals to track the orientation of a solar surface or surfaces is proposed. Two dispersive prisms or gratings arranged in a mirror-symmetric fashion are used to decompose light into its constituent colors, and the gain of a differential amplifier circuit based on the difference of the frequencies of single color collimated light produced by the two prisms or gratings is used to maintain the on-sun orientation of the solar surface or surfaces.
