An Apple patent detailing pressure-sensitive touchscreens was published today by the United States Patent and Trademark Office, reports AppleInsider. Entitled "Gesture and touch input detection through force sensing," the application describes a system in which a traditional touchscreen is complemented by multiple force-sensors in order to better log unique gestures and more complex input.
The touch screen is configured to detect a touch signal corresponding to a user finger approaching or contacting the touch screen. The at least three pressure sensors are configured to detect a pressure signal corresponding to an object proving pressure on a surface. In response to the pressure signal the processor determines a centroid location relative to the surface and the touch signal is processed by the processor by analyzing the centroid location.
Furthermore, the patent notes that the force sensors can be positioned outside of an active touch region, which could allow for users to interact with user interface elements such as menu options that extend well beyond the immediate area of a touchscreen. This would allow a device the option to render more elements onscreen while retaining key touch elements needed offscreen, offering a secondary mode of input.
Currently, it is unknown whether Apple plans to create such a touchscreen for its products or not, but the company has shown an interest in pressure sensitive technology before. An Apple patent detailing the integration of a pressure sensitive button in a touchscreen was published last November, and a patent that described pressure-sensitive device casings was awarded to Apple in March 2013.
The patent application, which was originally filed on January 30, 2012 and published today, also lists Nima Parivar and Wayne C. Westerman as its inventors.
