Abstract

TOUCH STRIP INPUT FOR DISPLAY TERMINAL
Abstract of the Disclosure The screen of a display terminal has touch strips extending adjacent horizontal and vertical edges. The touch strips have electrical outputs dependent on the position along the strips at which they are touched. Using microprocessor control the touch strips can be made to manipulate a displayed image and control the rate or level of other terminal functions. By selecting an appropriate programming mode the touch strips can be made to present a series of programmable or soft keys.
Also the touch strips can be used to provide a menu selection, scrolling and cursor generation and movement for word processing. The use of two touch strips requires less complex circuitry than a known transparent input overlay for the display screen. Moreover, it is a cleaner technique resulting in reduced image attenuation and distortion.

Claims (16)

THE EMBODIMENTS OF THE INVENTION IN WHICH AN EXCLUSIVE
PROPERTY OR PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS:-
1. A terminal comprising a rectangular display screen, display means for displaying an image on the screen, a position sensitive touch strip spaced from the screen, mounted along one side thereof and extending the length of the screen, voltage generating means for generating a voltage in response to the touch strip being touched, the voltage level corresponding to the position at which the strip is touched, a selector for selecting one of a plurality of possible display modes, an input interface unit having inputs from said voltage generating means and from said selector, a microprocessing unit having an input from the input interface unit and an output to an output interface unit, the output interface unit having an output controlling said display means, the microprocessing unit having stored therein a control program which determines the display mode in response to an input from the selector and determines image detail in response to an input from the voltage generating means.
2. A terminal as claimed in claim 1 wherein in response to a selectable output from the selector, the control program defines both a plurality of individually energizable discrete lengths within the touch strip, and a corresponding plurality of regions of the display screen.
3. A terminal as claimed in claim 2 wherein the control program functions to preclude input data originating when the touch strip is touched other than at positions within said discrete lengths.
4. A terminal as claimed in claim 1, the terminal particularly adapted for a display operating mode in which the display depends on a continuously variably operating parameter, the terminal further comprising control means for controlling the value of the variable operating parameter, and wherein in response to a selected output of the selector, the control program initiates an output to select said control means and in response to an output of the touch strip, the control program initiates an output to the control means to drive the value of the parameter to a value corresponding to the position at which the touch strip is touched.
5. A terminal as claimed in claim 1 particularly adapted for a scrolling display operating mode wherein, in response to a selected output of the selector, the control program prepares the microprocessing unit unit to receive scrolling data, the control program further responding to an input from the touch strip corresponding to unidirectional stroking thereof to drive the display means to scroll the displayed image.
6. A terminal as claimed in claim 1 in which said touch strip is mounted at a location spaced from said side of said screen.
7. A terminal as claimed in claim 1 in which a second touch strip extends along another side of the rectangular screen in a direction substantially perpendicular to the direction in which the first touch strip extends, the terminal including a further voltage generating means for generating a voltage in response to the second touch strip being touched, the second voltage level corresponding to the position at which the second strip is touched.
8. A terminal as claimed in claim 7 particularly adapted for a display operating mode using a cursor wherein in response to a selected output of the selector, the control program prepares the microprocessing unit to receive cursor positional data and instructs the display means to generate a cursor in the displayed image, the control program further responding to inputs from the touch strips to drive the display means to alter the cursor position on the screen in directions parallel to the strips.
9. A terminal as claimed in claim 2 in which the discrete lengths of the touch strip correspond in length and position to the plurality of regions in the screen adjacent to the touch strip designations and the screen regions.
10. A terminal as claimed in claim 9 in which the screen regions extend along a marginal portion of the screen immediately adjacent to the touch strip.
11, A terminal as claimed in claim 10 in which the display is of the raster scan type in which a frame consists of a plurality of horizontal scan lines, the touch strip being horizontal and the screen regions occupying a plurality of lines at the end of the raster scan.
12. A terminal as claimed in claim 10 in which the display is of the raster scan type having a plurality of horizontal scan lines, the touch strip extending vertically and the screen regions occupying vertically aligned parts at one end of the raster scan lines.
13. A terminal as claimed in claim 1 in which the screen is surrounded by a frame and the touch strip is mounted on the frame.
14. A terminal as claimed in claim 1 in which the touch strip is mounted by means of an adhesive.
15. A terminal as claimed in claim 1 in which the frame projects forwardly of the screen, the touch strip located on an edge of the frame immediately adjacent to the screen.
16. A terminal as claimed in claim 1 in which the strip is mounted on a control panel angled relative to the screen.
