MOBILE TERMINAL
First Claim
1. A mobile terminal, comprising:
- a first manipulating unit adapted to receive first inputs comprising one of a plurality of movement directions with respect to a reference position, and adapted to activate one or more functions corresponding to each of the plurality of movement directions;
a second manipulating unit located near the first manipulating unit, the second manipulating unit being touch-sensitive; and
an erroneous input detecting unit adapted to detect touches made between the first and second manipulating units and to identify certain touch inputs made on the second manipulating unit as unintended inputs, by comparing signals generated when the second manipulating unit is touched and signals generated by touches made adjacent to the second manipulating unit.

Abstract
An input device for reducing an erroneous operation and a mobile terminal having the same are disclosed. The input device includes: a first manipulating unit that has a plurality of movement directions based on a reference position and performing an input operation corresponding to each movement direction; a second manipulating unit disposed around the first manipulating unit and inputting information in a touch (tactile) manner; and an erroneous input detecting unit, which is installed to allow detection of user touches between the first and second manipulating units, can distinguish user inputs that were not intended to be made on the second manipulating unit, by comparing the signals generated when the second manipulating unit is actually operated and the signals generated by erroneous touches made adjacent to the second manipulating unit.

6. A mobile terminal, comprising:
-
a wheel input unit adapted to detect forward and reverse wheel motions, and to activate one or more functions corresponding to the forward and reverse wheel motions; a touch sensitive input device disposed at a central portion of the wheel input unit; and a touch input discriminator adapted to detect a touch near the touch sensitive input device and to identify certain touch inputs near the touch sensitive input device to be erroneous touch inputs, by comparing a signal generated when the touch sensitive input device is touched and a signal generated when the touch input discriminator is touched. - View Dependent Claims (7, 8, 9, 10)

11. A mobile terminal, comprising:
-
a first touch-sensitive input device adapted to detect forward and reverse circular touches and to activate one or more functions corresponding to the forward and reverse touches; a second touch-sensitive input device disposed near the first touch-sensitive input device; a third touch-sensitive input device disposed in a central portion of the first touch-sensitive input device; and a touch detector adapted to detect touches between the first and second touch-sensitive input devices, and to identify certain touches made on the third touch-sensitive input device to be unintentional inputs when the second touch-sensitive input device is touched, and also identify other inputs to be additional unintentional inputs made on the second touch-sensitive input device when the third touch-sensitive input device is touched, by comparing signals generated when the second and third touch-sensitive input devices are touched to signals generated by touches to the touch detector. - View Dependent Claims (12, 13, 14, 15)

16. A method of controlling a mobile terminal, comprising:
-
receiving in the mobile terminal first inputs comprising one of a plurality of movement directions with respect to a reference position, and activating one or more functions corresponding to each of the plurality of movement directions; and detecting touches made between first and second manipulating units and identifying certain touch inputs made on the second manipulating unit as unintended inputs, by comparing signals generated when the second manipulating unit is touched and signals generated by touches made adjacent to the second manipulating unit.

17. A method of controlling a mobile terminal, comprising:
-
detecting forward and reverse wheel motions, and activating one or more functions corresponding to the forward and reverse wheel motions; and detecting a touch near a touch sensitive input device and identifying certain touch inputs near the touch sensitive input device to be erroneous touch inputs, by comparing a signal generated when the touch sensitive input device is touched and a signal generated when a touch input discriminator is touched.

18. A method of controlling a mobile terminal, comprising:
-
detecting forward and reverse circular touches and activating one or more functions corresponding to the forward and reverse touches; and detecting touches between first and second touch-sensitive input devices, and identifying certain touches made on a third touch-sensitive input device to be unintentional inputs when the second touch-sensitive input device is touched, and also identifying other inputs to be additional unintentional inputs made on the second touch-sensitive input device when the third touch-sensitive input device is touched, by comparing signals generated when the second and third touch-sensitive input devices are touched to signals generated by touches to a touch detector.
