Operation instruction system and computer readable storage medium to be used for the same
A display device system for driving a display having one of a plurality of predetermined sizes provides a scalable instruction picture to instruct an operator in operation of input devices. The system includes a device for accepting an operator input selecting a scaling factor to adjust the size of the instruction picture such that indicators in the instruction picture are arranged at spacings substantially equal to spacing of the input devices. In an embodiment, the size of the instruction picture is only adjusted in a width wise horizontal direction. Furthermore, scaling indicators corresponding to a plurality of predetermined display sizes are optionally provided to permit the user to select a scaling factor corresponding to the display.
1. A display device system for driving a display having one of a plurality of predetermined sizes to instruct an operator in operation of an input device having operation input portions arranged in a horizontal direction corresponding to a horizontal display direction and at predetermined input portions spacings, the display device system comprising:
a display device for displaying an operation instruction picture on the display showing:
an operation instruction area having operation instruction indicators which indicate to the operator operations of the operation input portions to be executed and which are arranged in the horizontal direction over a width of the operation instruction area in a one-to-one correspondence with the operation input portions of the input device; and
a plurality of scale indicators corresponding respectively to said plurality of predetermined sizes of the display device; and
a control device responsive to an operator input selecting one of said plurality of scale indicators, corresponding to the display, for adjusting only a width of the operation instruction area in the horizontal direction such that spacings of the operation instruction indicators on the display substantially equal the predetermined input portions spacings of the operation input portions and such that the width of the operation instruction area substantially equals a width range of the arrangement of the operation input portions.
2. The display device system of claim 1 wherein said plurality of scale indicators are arranged on the display to indicate varying widths of said operation instruction area.
3. The display device system of claim 2 wherein said control device accepts the operator input selecting widths of the operation instruction area which do not correspond to said plurality of scale indicators and provides a visual indication when a selected width corresponds to one of said plurality of scale indicators.
4. The display device system of claim 1 wherein said control device accepts the operator input selecting widths of the operation instruction area which do not correspond to said plurality of scale indicators and provides a visual indication when a selected width corresponds to one of said plurality of scale indicators.
5. A computer readable storage medium storing an executable program for driving a display having one of a plurality of predetermined sizes to instruct an operator in operation of an input device having operation input portions arranged in a horizontal direction corresponding to a horizontal display direction and at predetermined input portions spacings, the program comprising steps for:
displaying an operation instruction picture on the display showing:
an operation instruction area having operation instruction indicators which indicate to the operator operations of the operation input portions to be executed and which are arranged in the horizontal direction over a width of the operation instruction area in a one-to-one correspondence with the operation input portions of the input device; and
a plurality of scale indicators corresponding respectively to said plurality of predetermined sizes of the display device; and
adjusting only a width of the operation instruction area in the horizontal direction such that spacings of the operation instruction indicators on the display substantially equal the predetermined input portions spacings of the operation input portions and such that the width of the operation instruction area substantially equals a width range of the arrangement of the operation input portions in response to an operator input selecting one of said plurality of scale indicators, corresponding to the display.
6. The recording medium of claim 5 wherein said plurality of scale indicators are arranged on the display to indicate varying widths of said operation instruction area.
7. The recording medium of claim 6 wherein said step of adjusting only a width of the operation instruction area includes accepting operator input selecting widths of the operation instruction area which do not correspond to said plurality of scale indicators and provides a visual indication when a selected width corresponds to one of said plurality of scale indicators.
8. The recording medium of claim 5 wherein said step of adjusting only a width of the operation instruction area includes accepting operator input selecting widths of the operation instruction area which do not correspond to said plurality of scale indicators and provides a visual indication when a selected width corresponds to one of said plurality of scale indicators.
