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.

CM,1. For an instrument comprising a screen, means for generating output signals indicating when an object is proximate said screen and indicating a particular touch zone area of a plurality of touch zone areas of said screen to which said object is proximate, and control means responsive to said output siqnals for generating displays of images on said screen, a method for said control means for responding to said output signals, the method comprising the steps of: monitoring said output signals to determine when an object is proximate said screen; determining from said output signals the particular touch zone to which said object is proximate; determining whether a portion of a particular image is displayed on said screen within boundaries of said particular touch zone; generating a display of a first indicating image on said screen visually distinguishing said particular image displayed on said screen when any portion of said particular image is included within boundaries of said particular touch zone; and generating a display of a second indicating image on said screen visually identifying said particular touch zone when no portion of any image displayed on said screen is included within boundaries of said particular touch zone.
