Portable terminal having motion-recognition capability and motion recognition method therefor
First Claim
Patent Images
1. 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, andwherein the predetermined threshold is variably set by averaging variations of initial input accelerations created during a pressing the motion key.

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.

7. 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. - View Dependent Claims (8, 9, 10, 11, 12)
