23. A method for controlling a generated pointer, comprising:
-
providing a pad occupying a region, a raised border at a perimeter of the region and a detecting device configured to detect a physical contact at any position on the border wherein contact with the border generates a signal indicating a contact position on the border; interpreting contact at a location on a border as a command to move a generated pointer in a respective direction; and moving the generated pointer in the respective dimension while the contact persists. - View Dependent Claims (24, 25)

26. A computer readable medium for controlling a generated pointer comprising a computer readable program, wherein the computer readable program when executed on a computer causes the computer to perform the steps of:
-
in a pointer device having a pad occupying a region, a raised border at a perimeter of the region and a detecting device configured to detect a physical contact at any position on the border wherein contact with the border generates a signal indicating a contact position on the border, interpreting contact at a location on a border as a command to move a generated pointer in a respective direction; and moving the generated pointer in the respective dimension while the contact persists.
