Abstract

A system includes at least three accelerometers disposed in different locations of an area with a surface to capture respective vibration data corresponding to a command tapped onto the surface by a user and a processing system to receive the vibration data from each accelerometer, identify the command and a location of the user from the vibration data, and generate a control signal based on the command and the location.

Claims

1. A system comprising:

at least three accelerometers disposed in different locations of an area to capture respective vibration data corresponding to a command tapped onto the surface by a user, the area including a surface; and

a processing system to receive the vibration data from each accelerometer, identify the command and a location of the user from the vibration data, and generate a control signal based on the command and the location.

2. The system of claim 1 wherein the processing system is to provide the control signal to a device in the area.

3. The system of claim 2 wherein the processing system is to select the device for receiving the control signal based on the location of the user.

4. The system of claim 2 wherein the processing system is to register the device and the command prior to receiving the vibration data.

5. The system of claim 2 wherein the processing system is to receive an acknowledge signal from the device in response to the control signal.

6. The system of claim 1 wherein the processing system is to identify the location of the user using triangulation.

7. The system of claim 1 wherein the accelerometers each include a proof mass with a first electrode array suspended above a second electrode array disposed on a wafer.

8. The system of claim 1 wherein the accelerometers each include three-phase sensing and actuation.

9. The system of claim 1 wherein the accelerometers each detect changes in capacitances between a first electrode arrays disposed on a proof mass and a second electrode array disposed on a wafer.

10. A method performed by a processing system, the method comprising:

receiving vibration data captured by at least three accelerometers disposed in different locations of an area in response to a user tapping a command on a surface in the area;

processing the vibration data with the processing system to identify the command and a user location;

generating a first control signal based on the command in response to the user location corresponding to a first predefined location in the area; and

generating a second control signal based on the command in response to the user location corresponding to a second predefined location in the area that differs from the first predefined location.

11. The method of claim 10 further comprising:

providing the first control signal to a first device in response to the user location corresponding to the first predefined location; and

providing the second control signal to a second device in response to the user location corresponding to the second predefined location.

12. The method of claim 10 wherein the first control signal causes a first function to be performed on a device, and wherein the second control signal causes a second function to be performed on the device.

13. The method of claim 10 further comprising:

identifying the user location by triangulating the vibration data.

14. A computer-readable storage medium storing instructions that, when executed by a processing system, perform a method comprising:

receiving first vibration data captured by at least three accelerometers disposed in different locations of an area in response to a user tapping a first command on a first surface in the area; and

generating a first control signal to cause a first function to be performed based on the first command and a first user location determined from the first vibration data.

15. The computer-readable storage medium of claim 14, the method further comprising:

receiving second vibration data captured by the at least three accelerometers while the user tapped a second command on a second surface in the area; and

generating a second control signal to cause a second function to be performed based on the second command and a second user location determined from the second vibration data, the second user location differing from the first user location.
