The touch and hover patent involves devices that can recognize something like a finger or stylus hovering above a display panel without actually touching the screen. The name of the patent is “Touch and hover signal drift compensation” and it describes a system in which a touchscreen display can accurately determine both hover and touch events.
According to the patent, “Some touch sensitive devices can also recognize a hover event, i.e., an object near but not touching the touch sensor panel, and the position of the hover event at the panel. The touch sensitive device can then process the hover event in a manner similar to that for a touch event, where the computing system can interpret the hover event in according with the display appearing at the time of the hover event, and thereafter can perform one or more actions based on the hover event.”
Brian Michael King, Omar Leung, Paul G. Puskarich, Jeffrey Traer Bernstein, Andrea Mucignat, Avi E. Cieplinski, Muhammad U. Choudry, Praveen R. Subramani, Marc J. Piche, David T. Amm and Duncan Robert Kerr were named in the patent as inventors.
