Abstract

An electronic device includes a housing that encloses a processor and a memory coupled to the processor. One or more tap sensors provide a tap signal in response to a user'"'"'s tap on an outside surface of the housing. A position detecting mechanism determines the position of a user'"'"'s tap on the outside surface of the housing based on the tap signal. In one embodiment, the position of the user'"'"'s tap is determined through triangulation using the tap signal from each of plural accelerometers mounted at different locations. A matching mechanism compares the determined position of the user'"'"'s tap and one or more virtual buttons configured on the outside surface of the housing. In accordance with the preferred embodiments, the size and location of one or more virtual buttons are dynamically configured by the user and/or by a software program loaded on the electronic device.

Claims

1. An electronic device, comprising:

a processor;

a memory coupled to the processor;

a housing having an outside surface, the housing at least partially enclosing the processor and the memory;

at least one tap sensor for providing a tap signal in response to a user'"'"'s tap on the outside surface of the housing;

a position detecting mechanism to determine the position of a user'"'"'s tap on the outside surface of the housing based on the tap signal;

a matching mechanism residing in the memory and executed by the processor to match the determined position of the user'"'"'s tap and one or more virtual buttons configured on the outside surface of the housing.

2. The electronic device as recited in claim 1, wherein the at least one tap sensor comprises a plurality of accelerometers mounted at different locations relative to the outside surface of the housing, and wherein the position detecting mechanism determines the position of the user'"'"'s tap through triangulation using the tap signal from each of the accelerometers.

3. The electronic device as recited in claim 1, wherein the position detecting mechanism resides in the memory and is executed by the processor.

4. The electronic device as recited in claim 1, wherein the outside surface of the housing includes a tap surface devoid of physical input buttons to provide an uninterrupted barrier between the outside of the housing and the inside of the housing at the tap surface.

5. The electronic device as recited in claim 1, further comprising a virtual button configuration mechanism residing in the memory and executed by the processor to dynamically configure one or more virtual buttons on the outside surface of the housing.

6. The electronic device as recited in claim 5, wherein the outside surface of the housing includes a hot key, and wherein the virtual button configuration mechanism defines the size of the one or more virtual buttons based on the length of time a user depresses the hot key.

7. The electronic device as recited in claim 5, wherein the outside surface of the housing includes a hot key, and wherein the virtual button configuration mechanism defines the location of the one or more virtual buttons based on where the outside surface of the housing is tapped after a user depresses the hot key.

8. The electronic device as recited in claim 5, wherein the virtual button configuration mechanism defines at least one of the size and the location of the one or more virtual buttons according to a software program residing in the memory and executed by the processor.

9. The electronic device as recited in claim 5, further comprising a display on the outside surface of the housing, and wherein the arrangement of the one or more virtual buttons is displayed on at least a portion of the display.

10. A method for entry of data or commands into an electronic device, comprising the steps of:

providing an electronic device with a housing having an outside surface, wherein the housing at least partially encloses a processor and a memory coupled to the processor, and wherein the housing has associated therewith at least one tap sensor that provides a tap signal in response to a user'"'"'s tap on the outside surface of the housing;

determining the position of a user'"'"'s tap on the outside surface of the housing based on the tap signal;

matching the determined position of the user'"'"'s tap and one or more virtual buttons configured on the outside surface of the housing.

11. The method as recited in claim 10, wherein the at least one tap sensor comprises a plurality of accelerometers mounted at different locations relative to the outside surface of the housing, and wherein the step of determining the position of the user'"'"'s tap includes the step of determining the position of the user'"'"'s tap through triangulation using the tap signal from each of the accelerometers.

12. The method as recited in claim 10, further comprising the step of dynamically configuring one or more virtual buttons on the outside surface of the housing, and wherein the matching step includes the step of comparing the determined position of the user'"'"'s tap and one or more portions of the outside surface of the housing defined in the configuring step as respectively constituting the one or more virtual buttons.

13. The method as recited in claim 12, wherein the outside surface of the housing includes a hot key, and wherein the configuring step includes the step of defining the size of the one or more virtual buttons based on the length of time a user depresses the hot key.

14. The method as recited in claim 12, wherein the outside surface of the housing includes a hot key, and wherein the configuring step includes the step of defining the location of the one or more virtual buttons based on where the outside surface of the housing is tapped after a user depresses the hot key.

15. The method as recited in claim 12, wherein the configuring step includes the step of defining at least one of the size and the location of the one or more virtual buttons according to a software program residing in the memory and executed by the processor.

16. The method as recited in claim 12, wherein the outside surface of the housing includes a display, and further comprising the step of displaying the arrangement of the one or more virtual buttons on at least a portion of the display.

17. A computer program product for entry of data or commands into an electronic device that includes a housing having an outside surface, wherein the housing at least partially encloses a processor and a memory coupled to the processor, wherein the housing has associated therewith at least one tap sensor that provides a tap signal in response to a user'"'"'s tap on the outside surface of the housing, the computer program product comprising a plurality of computer executable instructions provided on computer readable signal bearing media, the program performing the steps of:

determining the position of a user'"'"'s tap on the outside surface of the housing based on the tap signal;

matching the determined position of the user'"'"'s tap and one or more virtual buttons configured on the outside surface of the housing.

18. The computer program product as recited in claim 17, wherein the at least one tap sensor comprises a plurality of accelerometers mounted at different locations relative to the outside surface of the housing, and wherein the step of determining the position of the user'"'"'s tap includes the step of determining the position of the user'"'"'s tap through triangulation using the tap signal from each of the accelerometers.

19. The computer program product as recited in claim 17, wherein the program further performs the step of dynamically configuring one or more virtual buttons on the outside surface of the housing, and wherein the matching step includes the step of comparing the determined position of the user'"'"'s tap and one or more portions of the outside surface of the housing defined in the configuring step as respectively constituting the one or more virtual buttons.
