Touch screen drag and drop input technique
First Claim
1. A method of dragging and dropping an item displayed on a touch screen, the method comprising:
- detecting a first location of an object touching a display of the item on the touch screen;
detecting that a pressure between the object and the touch screen at the first location is greater than a first predetermined pressure for a first predetermined period of time;
detecting a decrease in the pressure between the object and the touch screen at the first location of a predetermined amount from the first predetermined pressure to a reduced pressure;
detecting movement of the object across the touch screen at the reduced pressure from the first location to a second location;
detecting that the pressure between the object and the touch screen at the second location is greater than a second predetermined pressure for a time duration greater than a second predetermined period of time; and
moving the display of the item from the first location on the touch screen to the second location on the touch screen.

Abstract
A method of and apparatus for dragging and dropping items displayed on a touch screen. In one embodiment, the item on the touch screen is touched with a pressure greater than a first predetermined pressure for a first predetermined period of time. The pressure on the item is then reduced, and the item is dragged with the reduced pressure to a second location at which the touch screen is touched with a pressure greater than a second predetermined pressure for a time duration greater than a second predetermined time period. In another embodiment, the item on the touch screen is touched with a pressure greater than a predetermined pressure for a first predetermined period of time, and then the touch screen is touched at a second location with a pressure greater than the predetermined pressure for a second predetermined period of time, less than the first predetermined period of time.

6. An apparatus for dragging and dropping an item displayed on a touch screen, the apparatus comprising:
-
a location detector for detecting a location of an object touching the touch screen;
a pressure detector for detecting a pressure between the object and the touch screen; and
a time duration measuring unit for measuring a time duration of the detection of the pressure between the object and the touch screen being greater than a first predetermined pressure or greater than a second predetermined pressure; and
wherein in response to the location detector detecting a first location on the touch screen when the pressure between the object and the touch screen at the first location exceeds a first predetermined pressure for a time duration greater than a first predetermined time, detecting movement of the object across the touch screen at a reduced pressure less than the first predetermined pressure by a predetermined amount, and detecting a second location on the touch screen when the pressure between the object and the touch screen at the second location exceeds a second predetermined pressure for a time duration greater than a second predetermined time period, an item displayed at the first location on the touch screen is dragged and dropped on the second location on the touch screen. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)

14. A method of dragging and dropping an item displayed on a touch screen, the method comprising:
-
detecting a first location of an object touching a display of the item on the touch screen;
detecting that a pressure between the object and the touch screen at the first location is greater than a predetermined pressure for a time duration greater than a first predetermined period of time;
detecting that a pressure between the object and the touch screen at a second location on the touch screen is greater than the predetermined pressure for a time duration greater than a second predetermined time period, the second predetermined time period being smaller than the first predetermined time period; and
moving the display of the item from the first location on the touch screen to the second location on the touch screen. - View Dependent Claims (15, 16, 17)

18. An apparatus for dragging and dropping an item displayed on a touch screen, the apparatus comprising:
-
a location detector for detecting a location of an object on the touch screen;
a pressure detector for detecting a pressure between the object and the touch screen; and
a time duration measuring unit for measuring a time duration of the detection of the pressure between the object and the touch screen being greater than a predetermined pressure;
wherein in response to the location detector detecting a first location on the touch when the pressure detector detects that the pressure between the object and the first location is greater than a predetermined pressure for a time duration greater than a first predetermined time period and detecting a second location on the touch screen when the pressure detector detects that the pressure between the object and the second location is greater than the predetermined pressure for a time duration greater than a second predetermined time period, the second predetermined time period being smaller than the first predetermined time period, an item disposed at the detected first location on the touch screen is dragged and dropped at the detected second location on the touch screen. - View Dependent Claims (19, 20, 21, 22, 23, 24)
