Abstract

A user interface device for use in controlling one or more external devices has at least a positional change operation mode and a keyboard operation mode. The user interface device has a main body portion, an orientation sensor, a surface sensor, a processor and a switch. The main body portion includes a top surface having at least one button that is active only in the positional change operation mode. The at least one button triggers an action in the one or more external devices when pressed. The bottom surface has a displacement sensor and a thumb keyboard. The displacement sensor detects positional change of the user interface device only during the positional change operation mode. The positional change is used for navigation on a display screen of the one or more external devices. The thumb keyboard has a plurality of keys that generate keyboard signals for sending to the one or more external devices only when the user interface device is in the keyboard operation mode. The plurality of keys allow for entry of at least alphabetic characters. The orientation sensor detects the orientation state of the user interface device. The surface sensor detects whether the bottom surface of the user interface device is touching an external surface. The processor includes processor logic that receives input signals from at least the orientation sensor and the surface sensor, and uses the input signals to determine whether to place the user interface device in either the positional change operation mode or the keyboard operation mode. The switch is configured to place the user interface device in either the positional change operation mode or the keyboard operation mode.

Claims

1. A user interface device for use in controlling at least one external device, the user interface device having at least (i) a positional change operation mode, and (ii) a keyboard operation mode, the user interface device comprising:

(a) a main body portion including;

(ii) a bottom surface including;

(A) a displacement sensor that detects positional change of the user interface device only during the positional change operation mode, the positional change being used for navigation on a display screen of the at least one external device, and

(B) a thumb keyboard having a plurality of keys that generate keyboard signals for sending to the at least one external device only when the user interface device is in the keyboard operation mode, the plurality of keys allowing for entry of at least alphabetic characters;

(b) an orientation sensor that detects the orientation state of the user interface device;

(c) a surface sensor that detects whether the bottom surface of the user interface device is touching an external surface;

(d) a processor including processor logic that receives input signals from at least the orientation sensor and the surface sensor, and uses the input signals to determine whether to place the user interface device in either the positional change operation mode or the keyboard operation mode; and

(e) a switch configured to place the user interface device in either the positional change operation mode or the keyboard operation mode.

2. The user interface device of claim 1 wherein the top surface includes two buttons.

3. The user interface device of claim 1 wherein the top surface includes a scroll wheel for use in scrolling a display associated with the at least one external device.

4. The user interface device of claim 1 wherein the displacement sensor is a scroll ball.

5. The user interface device of claim 1 wherein the displacement sensor is an optical sensor.

6. The user interface device of claim 1 wherein the displacement sensor detects positional change of the user interface device on a touched external surface.

7. The user interface device of claim 1 wherein the bottom surface is substantially planar.

8. The user interface device of claim 1 wherein the bottom surface includes a raised edge around at least a portion of its periphery, the thumb keyboard thereby being recessed so that when the device is moved along a touched external surface, the thumb keyboard is not in contact with the touched external surface.

9. The user interface device of claim 1 wherein the bottom surface includes a plurality of pads that extend from the bottom surface further than the keys of the thumb keyboard, the thumb keyboard thereby being recessed with respect to a plane formed by the plurality of pads so that when the device is moved along a touched external surface, the thumb keyboard is not in contact with the touched external surface, or is not in any significant contact with the touched external surface.

10. The user interface device of claim 1 wherein the thumb keyboard is a touchscreen that displays a virtual thumb keyboard.

11. The user interface device of claim 1 further comprising:

(f) gyroscopic or inertial sensors that detect positional change of the user interface device, the positional change being used for navigation on a display screen of the at least one external device when the user interface device is in the positional change operation mode and the bottom surface is not in contact with a touched external surface, the processor logic being further configured to control the switch to turn off the displacement sensor when the gyroscopic or inertial sensors are active.

12. The user interface device of claim 1 further comprising:

(f) a cell phone, wherein the keyboard signals are sent to the at least one external device via the cell phone.
