Abstract
A method for changing a transparency level of a virtual keypad on a display, comprising the steps of: activating a pointing device on the display; and dragging the pointing device along the display for a predetermined distance; whereby said dragging step causes the transparency level of the virtual keypad on the display to change. The keypad can be arranged to include a stacked intuitive layout for keys, where the left side of a qwerty keyboard is placed over the right side of a qwerty keyboard to created a stacked virtual keyboard.

11. A device with a variable transparency virtual keypad overlay, said device comprising:
-
a display; a pointing device for input on said display; and a processor configured to; register when a pointing device is activated and determine that said pointing device has been dragged for a predetermined distance greater than a minimum threshold, a cause the transparency level of the virtual keypad on the display to change by a predetermined amount in response to dragging said pointing device for said distance. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A method of creating pulsation in a virtual keyboard comprising the steps of:
-
setting a maximum transparency level, a minimum transparency level, and a delta transparency level; while the virtual keyboard is visible, checking whether the current keyboard transparency level is greater than the maximum transparency level or less than the minimum transparency level, and if yes, changing the sign of the delta transparency level; adding the delta transparency level to the current keyboard transparency level to form a new current keyboard transparency level; displaying the virtual keyboard at the new current keyboard transparency level; waiting for a predetermined time period; and looping back to the checking step. - View Dependent Claims (21)
