Abstract

A control panel for an electronic device includes a sensor array capable of sensing a location along the sensor array of a finger proximate to the sensor array. A channel on the control panel defines a guide path in register with at least a portion of the sensor array and is sized to receive a portion of a finger. The channel is operable to guide a finger of a user along the sensor array, and the sensed location of the finger along the sensor array can be used as an indication of an input selection by the user.

16. The control panel according to claim 1, further comprising indicators located adjacent the channel and operably coupled with the sensor array to communicate to the user the input selection corresponding to the sensed location of the finger along the sensor array.

17. The control panel according to claim 16 wherein the indicators comprise an illumination source.

18. The control panel according to claim 16 wherein the outer panel comprises a rib adjacent the channel, and the indicators are associated with the rib.

19. The control panel according to claim 18 wherein the rib is raised above the nominal surface.

20. The control panel according to claim 1, further comprising at least one switch coupled with the support panel and at least one depression formed in the outer panel and spaced from the channel in register with the at least one switch.

21. The control panel according to claim 20 wherein actuation of the at least one switch by a finger proximate to the at least one depression is used as an indication of one of a selection and deselection by the user of at least one option for the input selection.

22. The control panel according to claim 21, further comprising at least one indicator located adjacent the at least one depression and operably coupled with the at least one switch to communicate to the user the at least one selected or deselected option for the input selection.

23. The control panel according to claim 22 wherein the at least one indicator comprises an illumination source.

24. The control panel according to claim 23 wherein the at least one illumination source illuminates in response to the sensed location of the finger along the sensor array.

25. The control panel according to claim 1 wherein the electronic device is a household appliance comprising a controller for implementing a mode of operation of the appliance and operably coupled with the sensor array, wherein the sensor array is operable to communicate to the controller the mode of operation as indicated by the location of the finger along the sensor array.
