PRE-TOUCH POINTER FOR CONTROL AND DATA ENTRY IN TOUCH-SCREEN DEVICES

摘要

A “Pre-Touch” pointer method and apparatus for facilitating data entry and control of touch-screen devices. As a user hovers finger(s) above a touch-screen device (before making contact), plurality of sensors detect the finger and based on the physical location of the finger, create a pointer that is offset from the location of finger (to prevent obstruction). Said pointer helps a user target the precisely desired target location by reducing its size as finger(s) approaches the screen. When contact is made by finger(s), the location of said offset pointer remains the same, but it could become invisible—to help prevent obstruction. Its properties can also change to help better visualize or interact with touch-screen devices.;12

1. A Pre-Touch pointer method for facilitating data entry via a touch-screen device comprising steps of:
a. detecting a finger hovering above of the touch-screen device within a predefined space; b. identifying the location on the touch-screen right below the finger as a touching location; c. monitoring movement of said finger above of the touch-screen device; d. creating a computer generated offset pointer on the touch-screen device; e. offsetting the location of said pointer from said touching location; f. reducing the size of said offset pointer on the touch-screen device as said finger gets closer to said touch-screen device; and g. moving said offset pointer along with the movement of said finger on the touch-screen device, whereby said offset pointer being in a shifted location with respect to the location of said finger on the touch-screen.
