Abstract

A method for identifying a single tap with a controller employing the method comprises following steps: (a) detecting the first hit-movement being conducted by the object touching the touch device; (b) starting a time-counting if a detected result of step (a) is “YES”; (c) detecting if the object leaves the touch device within the first reference time interval; (d) generating an operation signal to represent a start of the hit-movement at the time of the first reference time interval ending if a detected result of step (c) is “YES”; (e) detecting if the second hit-movement is conducted by the object touching the touch device within a second reference time interval after the first reference time interval; (f) maintaining the operation signal to represent the second hit-movement being conducted if a detected result of step (e) is “YES”; and (g) terminating said operation signal at the time of the second reference time interval ending to represent a cease of the second hit-movement if a detected result of said step (e) is “NO” for completing the single tap.

Claims

1. A method for identifying a single tap during an object contacting a touch device comprising following steps:

(a) detecting a first hit-movement being conducted by said object touching said touch device;

(b) starting a time-counting if a detected result of step (a) is “

YES”

;

(c) detecting if said object leaves said touch device within a first reference time interval;

(d) generating an operation signal to represent a start of said hit-movement at the time of said first reference time interval ending if a detected result of step (c) is “

YES”

;

(e) detecting if a second hit-movement is conducted by said object touching said touch device within a second reference time interval after said first reference time interval;

(f) maintaining said operation signal to represent said second hit-movement being conducted if a detected result of said step (e) is “

YES”

; and

(g) terminating said operation signal at the time of said second reference time interval ending to represent a cease of said second hit-movement if a detected result of said step (e) is “

NO”

for completing said single tap.

2. A controller, which is capable of identifying a movement of an object on a touch device, comprising:

a touch-detect unit detecting a first hit-movement of said object touching said touch device and generating a touch signal corresponding to said first hit-movement;

a timer unit to count a time duration from said object initially contacting said touch device till said object leaving said touch device; and

a gesture-operation unit determining if an operation signal is generated at the time of a first reference time interval ending to represent a start of said first hit-movement based on a detected result of said touch-detect unit showing said first hit-movement occurring within said first reference time interval, maintaining said operation signal in a second reference time interval based on another detected result of said object touching said touch device showing a second hit-movement occurring within said second reference time interval, and terminating said operation signal at the time of said second reference time interval ending if said second hit-movement does not occur within said second reference time interval.

3. A method for identifying double taps during an object contacting a touch device comprising following steps:

(a) detecting a first hit-movement of said object touching said touch device;

(b) starting a time-counting if a detected result of step (a) is “

YES”

;

(c) detecting if said object leaves said touch device within a first reference time interval;

(d) generating a first operation signal to represent a start of said first hit-movement at the time of said first reference time interval ending if a detected result of step (c) is “

YES”

;

(e) detecting if a second hit-movement of said object touching said touch device and then leaving said touch device within a second reference time interval after said first reference time interval;

(f) terminating said first operation signal to represent a cease of said first hit-movement during said second reference time interval if a detected result of said step (e) is “

YES”

; and

(g) generating a second operation signal and then terminating said second operation signal to represent said second hit-movement for completing said double taps.

4. A controller, which is capable of identifying a movement of an object on a touch device, comprising:

a touch-detect unit detecting a first hit-movement of said object touching said touch device and generating a touch signal corresponding to said first hit-movement;

a timer unit counting a time duration from an initiation of said hit-movement till a cease of said first hit-movement; and

a gesture-operation unit determining if a first operation signal is generated at the time of a first reference time interval ending to represent a start of said first hit-movement based on a detected result of said touch-detect unit showing said first hit-movement occurring within said first reference time interval, terminating said first operation signal at the time of a second reference time interval to represent said cease of said first hit-movement based on another detected result of said touch-detect unit showing a second hit-movement of said object touching said touch device and then leaving said touch device within said second reference time interval, and generating and terminating a second operation signal to represent a start and a cease of said second hit-movement for completing said double taps.

5. A method for identifying a drag during an object contacting a touch device comprising following steps:

(a) detecting if a first hit-movement being conducted by said object touching said touch device;

(b) starting a time-counting if a detected result of step (a) is “

YES”

;

(c) detecting if said object leaves said touch device within a first reference time interval;

(d) generating a first operation signal to represent a start of said first hit-movement at the time of said first reference time interval ending if a detected result of step (c) is “

YES”

;

(e) detecting if a second hit-movement being conducted by said object touching said touch device and then leaves said touch device within a second reference time interval after said first reference time interval; and

(f) generating a second operation signal continuously till a cease of said second hit-movement has been detected by said touch-detect device for completing said drag.

6. A controller, which is capable of identifying a movement of an object on a touch device, comprising:

a touch-detect unit detecting a first hit-movement of said object touching said touch device and generating a touch signal corresponding to said first hit-movement;

a timer unit counting a time duration from said object initially contacting said touch device till said object leaving said touch device; and

a gesture-operation unit determining if a first operation signal is generated at the time of a first reference time interval ending to represent a start of said first hit-movement based on a detected result of said touch-detect unit showing said first hit-movement occurring within said first reference time interval, determining a second hit-movement of said object occurring within a second reference time without leaving said touch device based on another detected result of said touch-detect device and continuously generating a second operation signal from said second reference time interval ending till a cease of said second hit-movement for completing said drag.
