APPARATUS AND METHOD FOR SENSING CONTINUAL TOUCH
First Claim
1. A touch sensing apparatus, being capable of recognizing continual touch, the device comprising:
- a first reference value, the first reference value being predetermined; and
a second reference value, being configured to be between a first touch value and the first reference value, the first touch value satisfying the first reference value and outputting a touch recognition signal,wherein the continual touch is recognized by having the touch recognition signal output again in case the second reference value is satisfied.

Abstract
A touch sensing apparatus and a method thereof that can recognize continual touch are disclosed. The touch sensing apparatus that is capable of recognizing continual touch, in accordance with an embodiment of the present invention can include: a first reference value, the first reference value being predetermined; and a second reference value, being configured to be between a first touch value and the first reference value, the first touch value satisfying the first reference value and outputting a touch recognition signal. The continual touch can be recognized by having the touch recognition signal output again in case the second reference value is satisfied. With the present invention, the key input can be still recognized even though the area or pressure of a finger is changed without removing the finger or the finger is momentarily removed and touched repeatedly.

8. A method of touch sensing, being capable of recognizing continual touch, the method comprising:
-
(a) comparing a value according to a change in touch with a predetermined first reference value; (b) outputting a touch recognition signal if the first reference value is satisfied as a result of the comparison in the step (a), and configuring a second reference value to be between a first touch value and the first reference value, the first touch value allowing the touch recognition signal to output; (c) comparing a value caused by a change in touch with the second reference value; and (d) outputting a touch recognition signal again if the second reference value is satisfied as a result of the comparison in the step (c). - View Dependent Claims (9, 10, 11, 12, 13)

14. A recorded medium tangibly embodying a program of instructions executable by a digital processing apparatus to execute a method of touch sensing that is capable of recognizing continual touch, the program being readable by the digital processing apparatus, the program executing:
-
(a) comparing a value according to a change in touch with a predetermined first reference value; (b) outputting a touch recognition signal if the first reference value is satisfied as a result of the comparison in the step (a), and configuring a second reference value to be between a first touch value and the first reference value, the first touch value allowing the touch recognition signal to output; (c) comparing a value caused by a change in touch with the second reference value; and (d) outputting a touch recognition signal again if the second reference value is satisfied as a result of the comparison in the step (c). - View Dependent Claims (15, 16, 17)
