Graphical user interface for devices having small tactile displays
First Claim
1. Apparatus having a touch sensitive display and circuitry responsive to the display to move a cursor according to movement of a finger thereon and effect input operations according to the position of a cursor in relation to a displayed image, the position of the cursor on the displayed image being displaced by a short distance from the point of contact of the finger with the display so that the position of the cursor when an input operation is effected is visible to the user, wherein the input operations comprise at least a first finger tap serving to define the position of the cursor and a second finger tap serving to confirm the position of the cursor as the point of effect desired by the user.

Abstract
Apparatus, such as personal digital assistants, mobile phones or mobile computers, is described having a touch sensitive display and circuitry responsive to the display to move a cursor according to movement of a finger thereon and effect input operations according to the position of a cursor in relation to a displayed image, the position of the cursor on the displayed image being displaced by a short distance from the point of contact of the finger with the display so that the position of the cursor when an input operation is effected is visible to the user. The input operations comprise at least a first finger tap serving to define the position of the cursor and a second finger tap serving to confirm the position of the cursor as the point of effect desired by the user.

10. A method for operating a touch sensitive display including circuitry responsive to the display to move a cursor according to movement of a finger thereon and effect input operations according to the position of a cursor in relation to a displayed image, the method comprising:
-
displaying a cursor at a position displaced by a short distance from the point of contact of the finger with the display so that the position of the cursor when an input operation is effected is visible to the user;
responding to a first finger tap by defining the position of the cursor; and
responding to a second finger tap to confirm the position of the cursor as the point of effect desired by the user.

- 11. A computer program for controlling apparatus having a touch sensitive display, the program comprising program elements for responding to signals from the display to move a cursor in a displayed image according to movement of a finger thereon and program elements for effecting input operations according to the position of a cursor in relation to the displayed image, the position of the cursor on the displayed image being displaced by a short distance from the point of contact of the finger with the display so that the position of the cursor when an input operation is effected is visible to the user, wherein the input operations comprise at least a first finger tap serving to define the position of the cursor and a second finger tap serving to confirm the position of the cursor as the point of effect desired by the user.

12. Apparatus having a touch sensitive display and circuitry responsive to the display to move a cursor according to movement of a finger thereon and effect input operations according to the position of a cursor in relation to a displayed image, the position of the cursor on the displayed image being displaced by a short distance from the point of contact of the finger with the display so that the position of the cursor when an input operation is effected is visible to the user, wherein the input operations comprise at least a first finger tap serving to define the position of the cursor and a second finger tap serving to confirm the position of the cursor as the point of effect desired by the user, wherein the input operations are associated with display elements that are smaller than a human finger. and are effected if the second finger tap is effected less than a predetermined time after the first finger tap and if the first finger tap is effected less than a predetermined distance from the contact point that determined the cursor position.
