Touchscreen feedback system. |
摘要 |
<p>A computer-based digital oscilloscope includes a touchscreen mechanism for generating output signals indicating when an operator has touched the oscilloscope's screen and identifying a particular touch zone area that the operator has touched from among a plurality of touch zone areas of the screen. A computer which controls display of waveforms and other images on the screen, monitors the touchscreen output signals to determine whether the operator is touching a touch zone and to determine whether a portion of a particular image other than a waveform is displayed on the screen within boundaries of the touch zone. The computer generates a display of a first indicating image on the screen visually identifying the touch zone when not portion of any image other than a waveform is displayed on the screen within boundaries of said particular touch zone, and generates a display of a second indicating image on the screen visually identifying an image other than a waveform when any portion of the image is displayed on the screen within boundaries of the touch zone.</p> |
