<p>The present invention removes the necessity of pressing the buttons to activate or deactivate the loudspeaker in the mobile phone for moving from 'handset mode' to 'hands free mode' and vice versa, during an ongoing call. The accelerometer in the mobile phone senses the angle at which the mobile phone is held, called the angle of orientation, on one or more axis; the computing system receives this information and processes this information and takes a decision whether to switch on the loudspeaker or to switch it off or to leave the situation unaltered. And then the computing system takes the action accordingly. Hence the user can activate or deactivate the mobile phone by rotating the mobile phone by some angles on a given axis. Similarly, the loudness of the speaker or the loudspeaker can also be controlled.</p> |
