Abstract
A method for inputting a character adapted for a handheld electronic device is provided. In the present method, a reference plane is determined first. Then, a tilting angle and a tilting direction of the handheld electronic device deviating from the reference plane are detected. Then, the tilting direction is indicated, and an input of a key of the keypad is received. Finally, a character corresponding to the key at the tilting direction is displayed on the handheld electronic device. Therefore, only two actions including tilting the handheld electronic device and pressing the key are required for the users to complete the input of a character. As such, the method is intuitive, convenient, and fast for inputting the character.

A method for inputting a character, adapted for a handheld electronic device having a keypad, the method comprising:
- determining a reference plane;
- detecting a tilting angle and a tilting direction of the handheld electronic device deviating from the reference plane, the step of detecting the tilting angle and the tilting direction comprises:
- determining whether the tilting angle is within a predetermined range of angle;
- if the tilting angle is within the predetermined range of angle, then identifying the tilting direction as the direction of the handheld electronic device deviating from the reference plane;
- and
- if the tilting angle is out of the predetermined range of angle, then identifying the handheld electronic device as not deviating from the reference plane;
- indicating the tilting direction;
- receiving an input from a key of the keypad;
- and
- displaying a character corresponding to the key tilting at the tilting direction.
A method for inputting a character, adapted for a handheld electronic device having a keypad, the method comprising:
- determining a reference plane;
- when a key of the keypad is pressed, detecting a tilting angle and a tilting direction of the handheld electronic device deviating from the reference plane;
- when the key is released, determining the tilting angle and the tilting direction of the handheld electronic device deviating from the reference plane, and the steps comprises:
- determining whether the tilting angle is within a predetermined range of angle;
- if the tilting angle is within the predetermined range of angle, then identifying the tilting direction as the direction of the handheld electronic device deviating from the reference plane;
- and
- if the tilting angle is out of the predetermined range of angle, then identifying the handheld electronic device as not deviating from the reference plane;
- and
- displaying a character corresponding to the key tilting at the tilting direction.
