HAND-HELD DEVICE WITH CHARACTER INPUT ROTARY WHEEL
First Claim
1. A hand-held device comprising:
- a rotary wheel having a plurality of positioning inputs;
a first switch;
a second switch;
an encoder responsive to operation on the rotary wheel and outputting positioning codes;
a memory storing a plurality of input modes, wherein each input mode includes a plurality of characters corresponding to the positioning codes; and
a controller configured for obtaining an input mode from the memory, and shifting a current input mode to the input mode obtained in responsive to an input from the first switch;
the controller inputs a character of the current input mode according to a positioning code that the encoder outputs in response to an input from the second switch.

Abstract
A hand-held device is provided. The hand-held device includes a rotary wheel, a first switch, a second switch, an encoder, a memory, and a controller. The rotary wheel has a plurality of positioning inputs. The encoder is responsive to operations on the rotary wheel and outputs positioning codes. The memory stores a plurality of input modes, wherein each input mode includes characters corresponding to positioning codes. The controller obtains an input mode from the memory, and shifts a current input mode to the input mode obtained in responsive to an input from the first switch. The controller inputs a character of the current input mode according to a positioning code that the encoder outputs in response to an input from the second switch. The above-mentioned rotary wheel can replace keyboard in the hand-held device.
