US Patent 8212790 Pressure sensitive controls

The use of pressure-sensitive controls is disclosed in which controls respond differently to different pressure applied by a stylus on a digitizer. Users interacting with displayed controls may modify the speed, increment, or other property of the control by pressing harder or softer. Devices that allow for the input of location and pressure information may use embodiments of the invention, including computers with pressure sensitive mice or digitizer tablets, PDAs, or tablet computers. Controls that may use pressure to augment their behavior include scrollbars, spinner controls, resize handles, buttons, drop down menus and so forth.
