METHOD AND APPARATUS FOR SELECTING AN OBJECT
A device and method for selecting objects on a touch-sensitive display are described. The device includes a touch-sensitive display for displaying at least one object, the touch-sensitive display responsive to a user input, a selection detection section operatively coupled to the touch-input display, the selection detection section configured to detect a back-and-forth movement of the user input when the input is in contact with the touch-sensitive display and to select an object on the touch-sensitive display for further operation when the back-and-forth motion is in proximity to the object.
1 . A display device comprising:
a touch-sensitive display for displaying at least one object, the touch-sensitive display responsive to a user input;
a selection detection section operatively coupled to the touch-input display, the selection detection section configured
(i) to detect a back-and-forth movement of the user input when the input is in contact with the touch-sensitive display; and
(ii) to select an object on the touch-sensitive display for further operation when the back-and-forth motion is detected in proximity to the at least one object.
2 . The display device of 1 , wherein the selection detection section is configured to select the object when a length of the back-and-forth motion is less than about 0.5 inches.
3 . The display device of 1 , wherein the selection detection section is configured to select the object when the back-and-forth movement is completed in less than about 300 milliseconds.
4 . The display device of 1 , wherein the further operation comprises a movement section configured to move the selected object to a user-defined position.
5 . The display device of claim 4 , wherein the movement section is configured to drag the selected object to the user-defined position.
6 . The display device of claim 4 , wherein the user-defined position is where the object is positioned when the drag is stopped with an end action.
7 . The display device of claim 4 , wherein the touch-sensitive display includes a grid of objects and the movement section is operable to move the selected object to a position on the grid of objects.
8 . The display device of claim 7 , wherein the movement section is configured to swap the position of the selected object with the position of one of the objects in the grid of objects.
9 . The display device of claim 7 , wherein the movement section is configured to shift the position of the objects in the grid of objects based upon the placement of selected object.
10 . The display device of claim 1 , wherein the further operation comprises an object utilities menu circuit.
11 . The display device of claim 10 , wherein the object utilities menu includes functionality related to cutting, pasting, copying and/or formatting the object.
12 . The display device of claim 1 , wherein the selection detection section is further configured to detect the direction of the back-and-forth motion and the further operation is based at least in part on the detected direction.
13 . The display device of claim 12 , wherein the further operation comprises a movement section and an object utilities menu circuit, and wherein the movement section is initiated when selection detection section selects the object after detecting a left-right-left motion and the utilities menu circuitry is initiated when selection detection section selects the object after detecting a right-left-right motion.
14 . The display device of claim 12 , wherein the further operation simulates functionality related to a left mouse click if the back-and-forth movement is detected to be a left-right-left movement and functionality related to a right mouse click if the back-and-forth movement is detected to be a right-left-right movement.
15 . The display device of 1 , wherein the user input is a stylus or a portion of the user's body in contact with the touch-sensitive display.
16 . A method of selecting an object on a touch-sensitive display including at least one object and being responsive to a user input, the method comprising:
detecting movement of a user input that is indicative of a user's desire to select an object, wherein the movement of the user input comprises touching the display with a back-and-forth motion in proximity to an object on the display; and
selecting the object for further operation based on the detection of the back-and-forth movement of the user input.
17 . The method of claim 16 , the detecting further comprising measuring the length of the back-and-forth motion of the user input and selecting the object if the distance is less than a predetermined length and measuring a duration of time for the back-and-forth movement and selecting the object if the time is less than a predetermined amount of time.
18 . The method of claim 17 , comprising selecting the object if the predetermined length is less than about 0.5 inches and the predetermined amount of time is less than about 400 milliseconds.
19 . The method of claim 16 , wherein the further operation comprises:
(i) moving the selected object on the touch-sensitive display, and/or
(ii) opening an object utilities menu.
20 . A program stored on a machine readable medium which, when executed by a machine, provides for selecting an object on a touch-sensitive display of a device by:
detecting a back-and-forth movement of a user input in contact with the touch-sensitive display;
selecting an object for further operation when the back-and-forth movement is detected in proximity to the object on the touch-sensitive display.
