A device is provided for capturing complete analog motion, rather than digital events. A beam of columnated light, generated from a laser emitting diode, it directed at a clear, rotatable ball bearing having a series of reflecting indicia within the surface of the ball bearing. The reflection of columnated light off of these indicia makes the analog motion of the ball bearing a capturable, optical event. A sensor reads through the clear ball bearing and converts this motion into memory. The raw data then goes into the temporary RAM, which holds all excess data as other date is streamed into the microprocessors. Those processors change the raw data into digital code, which can then be understood and translated by most modern personal computers. The digital code can then be stored in the unit's non-volatile RAM, where it remains until it is uploaded into a PC resident software program.
