Abstract
A motion-recognition portable terminal and a motion recognition method therefor are provided. In the portable terminal, a motion key starts to create a motion entry, upon activation. A motion detector measures an acceleration along each axis of the portable terminal, upon activation of the motion key. A controller determines whether the motion entry has been completed based on the variation of the each-axis acceleration.
Claims12
A portable terminal comprising:
- a motion key for starting to create a motion entry, upon activation;
- a motion detector for measuring an acceleration along each axis of the portable terminal, upon activation of the motion key;
- and
- a controller for determining whether the motion entry has been completed based on a variation of the acceleration along each axis,
- wherein the controller determines that the motion entry has been completed if a halt period lasts for a predetermined time after a motion period, the halt period being a time period in which the variation of the acceleration along each axis is less than a predetermined threshold, and the motion period being a time period in which the variation of the acceleration along each axis is greater than the threshold, and
- wherein the predetermined threshold is variably set by averaging variations of initial input accelerations created during a pressing the motion key.

A method of detecting motion entry completion in a portable terminal, comprising the steps of:
- activating a motion key;
- creating a motion entry upon activation of the motion key;
- measuring an acceleration along each axis of the portable terminal;
- and
- determining whether the motion entry has been completed based on a variation of the acceleration along each axis,
- wherein the motion entry is determined to be completed if a halt period lasts for a predetermined time after a motion period, the halt period being a time period in which the variation of the acceleration along each axis is less than a predetermined threshold, and the motion period being a time period in which the variation of the acceleration along each axis is greater than the threshold, and
- wherein the predetermined threshold is variably set by averaging variations of initial input accelerations created during a pressing the motion key.
