Abstract

A method of controlling a screen pointer (cursor) is based on the general optical computer mouse by sensing the motion of an object (306/309) on the surface of an object motion detector unit (302/303/402/502). The method can be implemented as a handheld multimode pointing device (301/401) or integrated the implemented pointing device module (502-503) in other device (501). The implemented device (101/301/401) can use in desktop pointing, handheld pointing and handwriting operation modes.

Claims

1. A method based on the general desktop computer mouse can comprise a multimode pointing device with an object motion detector unit (without mechanical moving parts in the detector unit) comprising of two detector sets which are used in different operation mode separately, the device can manipulate in three modes as:

in desktop pointing mode putting the window surface of the active detector set on the desk surface the device can use as a general computer mouse,

in handheld pointing mode the user can hold the device in hand and use it as a pointing device by moving an object on the window surface or the detectable area of the active detector set,

in handwriting mode the device is used as handwriting input device, the user can write on the window surface or the detectable area of the active detector set with an object like a stylus or other tools,

then from the object motion detected by the detector unit the device can compute the object motion data and transmit the data to display device through air or cable interface, the display device can translate the object motion data to the actions in the display device.

2. The method according to claim 1, wherein the object motion detector unit described in claim 1 can be configured by replacing the two object motion detector sets with a single appropriate type of object motion detector set, in this configuration the implemented pointing device can manipulate in the three modes with the same ways mentioned in claim 1.

3. The method according to claim 1, wherein the object motion detector sets of the detector unit described in claim 1 can be implemented in a variety of types of detectors, such as optical detector, thermal detector, ultrasonic transceiver, touch sensor and so on, the two detector sets can be implemented with same type or different type of detectors, for example equipping an optical detector as one detector set that can use for the operation of desktop pointing mode and installing the other detector set with different type of detector (like thermal detector, touch sensor or ultrasonic transceiver) for the operation of handheld pointing mode;

the above mentioned detectors all can also use for the operation of handwriting mode.

4. The method according to claim 1, wherein one of the object motion detector sets of the detector unit described in claim 1 can be also implemented with other category of sensors that can sense the rapid movement of the implemented device itself. An example of this kind of sensor is the acceleration sensor, also know as the accelerometer. The user can hold the device implemented with acceleration sensor set and move the said device rapidly (like swinging the user'"'"'s arm), then the said device can detect its acceleration motion and can determine the device motion data and send the data to display device.

5. The method according to claim 1, wherein an element of the implemented pointing device is used for setting the operation mode mentioned in claim 1, the said element can comprise of different kind of parts and manipulate in different ways to set the operation modes of the said device, for example, a multi-position switch can set the operation mode manually, and an electronic gyro or a light sensor can set the operation mode automatically, the detail of the said element can refer to “

check operation mode”

step 201″ and

example 8.

6. The method according to claim 1, wherein the implemented multimode pointing device module can be integrated in a device that provides the pointing related functions, for example the said pointing device module can be integrated in keyboard, display device, computer tablet device, mobile phone, TV set, remote controller, watch type device, camera device, electronic game device, and so on.
