Abstract

A portable information device has an action recognizing function. An action detector precisely detects a single 3-dimensional movement of the device. A plurality of reference action patterns each linked to predetermined functions are registered in an action shortcut table. An action comparator compares the input action with the registered reference action patterns to activate a corresponding function.

Claims

1. A portable device having an action recognizing function, comprising:

an action detector for detecting a single 3-dimensional movement of the portable device;

a memory for storing a plurality of reference action patterns each representing a plurality of predetermined single 3-dimensional movements of the portable device; and

an action recognizer for recognizing an input single 3-dimensional movement of the portable device as one of the plurality of reference action patterns,

a reference action pattern manager for managing the plurality of reference action patterns stored in the memory such that the plurality of reference action patterns are registered, maintained or updated based on an input single 3-dimensional movement of the portable device; and

an action comparator for comparing the input single 3-dimensional movement of the portable device with the plurality of reference action patterns to determine a reference action pattern that substantially matches the input single 3-dimensional movement of the portable device,

wherein each of the plurality of reference action patterns stored in the memory comprises a plurality of sets of sampled data, each of which contains an angle acceleration vector, a roll angle, a pitch angle, and a bearing of the portable device.

2. The portable device according to claim 1, wherein each of the sets of sampled data includes error parameters representing individual characteristics of actions.

3. A portable device having an action recognizing function, comprising:

an action detector for detecting a single 3-dimensional movement of the portable device;

a memory for storing a plurality of reference action patterns each representing a plurality of predetermined single 3-dimensional movements of the portable device; and

an action recognizer for recognizing an input single 3-dimensional movement of the portable device as one of the plurality of reference action patterns,

wherein the action detector comprises;

a tilt detector for detecting a tilt of the portable device;

an acceleration detector for detecting an acceleration working on the portable device;

a magnetic compass detector for detecting a magnetic force working on the portable device; and

a state calculator for calculating the single 3-dimensional movement of the portable device based on the tilt, the acceleration and the magnetic force.

4. The portable device according to claim 3,

wherein the state calculator calculates a reference direction from the tilt, the acceleration and the magnetic force to determine the single 3-dimensional movement of the portable device at predetermined sampling intervals.

5. The portable device according to claim 4, wherein each sampled data contains an angle acceleration vector, a roll angle, a pitch angle, and a magnetic bearing of the portable device.

6. The portable device according to claim 5, wherein each of the angle acceleration vector, the roll angle, the pitch angle and the magnetic bearing is attached with an error parameter representing individual characteristics of action.

7. An action shortcut method in a portable device having a plurality of predetermined functions, comprising:
