CONTROL SYSTEM AND METHOD USING AN ULTRASONIC AREA ARRAY

摘要

A computer control system and method is disclosed. The system includes a processor and an ultrasonic area-array sensor configured to receive a ridged surface, such as one or more digits of a hand. The processor acquires a first information set from the sensor, the first information set representing at least a portion of the ridged surface, acquires a second information set from the sensor, the second information set representing at least a portion of the ridged surface, compares the first information set with the second information set to identify a common feature of the ridged surface that is present in both the first information and second information sets, determines a first position of the common feature using the first information set, determines a second position of the common feature using the second information set, and calculates a control measurement by comparing the first and second positions.
