DATA INPUT UNIT |
摘要 |
Data can be entered at the face of a CRT display of a computer system by an operator who presses his finger at any selected location on a faceplate overlying the CRT. The faceplate is supported by spaced piezoelectric elements, and their collective outputs are processed to identify the point of application of finger pressure on the faceplate, and hence the identity of data to be entered. The technique of processing the collective outputs includes features to give accurate identification of the point of application of force. |
