Abstract

A smart handheld device with a touch screen which can be used as a 2D or 3D mouse to control applications running on a host device. The smart device can include an optical sensor for, when a motion capture mode is activated, automatically detecting that it lies on a surface, measuring displacements of the device on the surface and emulating displacements of a cursor on the screen of the host device. The smart device can include a two axes gyroscope which can, when the motion capture mode is activated, measure yaw and pitch of the device in free space and convert changes in orientation measurements into displacements of a cursor on the screen of the host device. The touch screen is divided into zones and sub-zones to control various applications running on the device or on the host. The zones are configurable through a graphical user interface.

Claims

1. A handheld device comprising at least one motion sensor and a touch screen, said device being capable of communicating signals from said sensor to a host device comprising a motion signals processing capability, wherein said touch screen of said handheld device comprises at least two touch zones which are operative to control at least an application running on said host device with movements of said handheld device on a surface or in free space, at the option of the user.

2. The handheld device of claim 1, wherein the at least one motion sensor is a gyroscope comprising at least two axes.

3. The handheld device of claim 2, wherein pitch and yaw orientation or displacement signals from said gyroscope are sent to the host device to be converted to two axes displacements of a cursor on a screen within an application running on the host device.

4. The handheld device of claim 3, further comprising a two axes accelerometer providing input to the motion signals processing capability to correct at least partially the roll of the handheld device.

5. The handheld device of claim 1, further comprising an optical sensor configured to trigger its operation in a surface motion capture mode when it detects that said handheld device lays down on a surface.

6. The handheld device of claim 5, wherein two axes position or displacement signals from said optical sensor are sent to the host device to be converted to two axes displacements of a cursor on a screen within an application running on the host device.

7. The handheld device of claim 1, wherein one of said at least two touch zones comprises at least three touch sub-zones, a first one of which is fit for switching from a surface motion capture mode to and from a free space motion capture mode, a second one being fit for performing a scroll command within the host application, the third one being fit for performing a select command within the host application.

8. The handheld device of claim 7, wherein the scroll and select commands within the host applications are programmable by a graphical user interface.

9. The handheld device of claim 7, wherein one of the touch sub-zones is also fit for switching to and from a gesture recognition mode.

10. The handheld device of claim 7, further comprising a fourth touch sub-zone which is configured to input context dependent commands to the host application.

11. The handheld device of claim 10, wherein the relative positioning of the four touch sub-zones can be changed to be suitable for use by a right-handed or a left-handed user.

12. The handheld device of claim 1, wherein one of said at least two touch zones comprises at least two touch sub-zones which control operation of host applications which are dependent on the context of the handheld device.

13. The handheld device of claim 12, wherein the at least two touch sub-zones which control operation of host applications which are dependent on the context of the handheld device are programmable by a graphical user interface.

14. The handheld device of claim 1, wherein one of said at least two touch zones comprises at least two touch sub-zones which control operation of said handheld device applications.

15. The handheld device of claim 1, further comprising a phone transmitter and receiver configured to be deactivated when said handheld device is in surface or free space motion detection mode.

16. A method for controlling at least an application running on a host device from a handheld device, said handheld device comprising at least one motion sensor and a touch screen and being capable of communicating signals from said sensor to a host device comprising a motion signals processing capability, wherein said method for controlling comprises steps of using motion of said handheld device on a surface or in free space at the option of a user and steps of commanding functions of said applications by said user touching zones of said touch screen.
