Multi-function slide control
A system can include a processor; memory operatively coupled to the processor; a display operatively coupled to the processor; a touch sensitive surface that comprises a slider region; and assignment circuitry that assigns one of a plurality of assignable system functions to the slider region.
1. A system comprising:
a processor;
memory operatively coupled to the processor;
a display housing that comprises a display operatively coupled to the processor;
audio circuitry operatively coupled to the processor;
a keyboard housing that comprises a keyboard and a touch sensitive surface that comprises a menu region and a slider region, wherein the menu region comprises a display brightness item and an audio volume item; and
assignment circuitry that assigns one of a plurality of assignable system functions to the slider region responsive to selection of one of the items, wherein the plurality of assignable system functions comprise a display system brightness function for brightness of the display and an audio system volume function for volume of the audio circuitry.
2. The system of claim 1 , the keyboard housing comprising a row of keys and wherein the slider region is disposed substantially parallel to the row of keys.
3. The system of claim 2 wherein the row of keys comprises a mechanically depressible row of keys of a mechanical keyboard.
4. The system of claim 1 wherein each of the menu items is selectable via touch input to instruct the assignment circuitry to assign a respective one of the plurality of assignable functions to the slider region.
5. The system of claim 1 wherein the plurality of assignable system functions comprises at least one firmware level function and at least one operating system level function.
6. The system of claim 1 wherein the plurality of assignable system functions comprises a security code function.
7. The system of claim 1 wherein the touch sensitive surface comprises a multi-touch sensitive surface.
8. The system of claim 1 comprising scaling circuitry that scales touch input via the slider region to an output value.
9. The system of claim 8 wherein the scaling circuitry comprises a minimum output value parameter and a maximum output value parameter.
10. The system of claim 8 wherein the scaling circuitry comprises at least one scaling function.
11. The system of claim 1 wherein the slider region comprises a null point that defines two portions of the slider region.
12. The system of claim 1 wherein the slider region comprises electroluminescent material.
13. The system of claim 12 comprising illumination circuitry that activates the electroluminescent material responsive to touch input via the slider region.
14. The system of claim 13 wherein the illumination circuitry activates the electroluminescent material to illuminate at least one of a series of indicators.
15. The system of claim 1 comprising a microcontroller that is operatively coupled to the touch sensitive surface and to the processor.
16. The system of claim 1 wherein the touch sensitive surface comprises an interface that comprises a clock line and a data line.
