First Claim
Patent Images
1. A touch input device performing a feedback according to a touch level, the touch input device comprising:
- a touch screen which displays a passcode input window;
a controller which generates a first control signal as to whether or not a touch on the passcode input window matches a predetermined passcode, and determines a touch level among a plurality of touch levels by using at least one of a pressure magnitude, area and time period of the touch; and
a memory which stores the predetermined passcode;
wherein the touch level is set to the predetermined passcode; and
wherein, before generating the first control signal, the controller generates a second control signal providing a feedback indicative of the determined touch level, and wherein the feedback for each of the plurality of touch levels cannot be intuitively correlated with the touch level.

Abstract
A touch input device performing a feedback according to a touch level may be provided that includes; a touch screen which displays a passcode input window; a controller which generates a first control signal as to whether or not a touch on the passcode input window matches a predetermined passcode, and determines a touch level among a plurality of touch levels by using at least one of a pressure magnitude, area and time period of the touch; and a memory which stores the predetermined passcode. The touch level is set to the predetermined passcode.

14. A feedback method according to a touch level in a touch input device, the feedback method comprising:
-
displaying a passcode input window on a touch screen; determining a touch level among a plurality of touch levels by using at least one of a pressure magnitude, area and time period of a touch on the passcode input window; generating a first control signal as to whether or not the touch matches a predetermined passcode to which a touch level has been set; and after the determination of the touch level and before the generation of the first control signal, generating a second control signal providing a feedback indicative of the touch level, and wherein the feedback for each of the plurality of touch levels cannot be intuitively correlated with the touch level. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)

23. A touch input device comprising:
-
a) a touch screen; b) a controller configured to; i) unlock the touch screen when a touch on the touch screen matches a predetermined passcode, the predetermined passcode comprising a touch level; ii) determine the touch level of the touch from among a plurality of touch levels, the touch level being based on a pressure magnitude, an area, or a time period of the touch; and iii) before unlocking the touch screen, generate a feedback indicative of the determined touch level of the touch, wherein the feedback cannot be intuitively correlated with the touch level; and c) a memory configured to store the predetermined passcode.
