Elements presented as fingers approach screen

Apple has been awarded a patent, No. 7,653,883, relating to a proximity-based touch interface for various devices. The patent claims cover methods for sensing an object, such as a finger, as it approaches a touchscreen or other components of an electronic device. The proximity data is then used to perform actions in the device, such as presenting user-interface elements.

A variety of companies already utilize proximity sensors in mobile devices such as smartphones. The iPhone uses proximity information to disable the touchscreen while the handset is used for a voice call, helping to prevent accidental input.

The latest patent describes proximity detection systems that can determine the distance between a finger and a display, along with its x and y coordinates above the interface. The system could also interact with additional sensors to detect the level of force when the finger touches the screen.

Although the patent claims describe a wide range of potential applications for the proximity-based technology, the drawings show several embodiments ranging in size from an iPod display to a tablet-size touchscreen. In an iPod, the system could be used to present a virtual scrollwheel on the interface as the user brings a finger close to the list of songs. The user can then control the on-screen scrollwheel to navigate through the interface.

Descriptions for the tablet-size device also show a virtual scrollwheel that is presented above the music management interface. While navigating with the scrollwheel, users could also bring their other hand over the interface to bring up the controls for volume and playback.

Aside from the media player, the drawings also show a window configuration similar to Mac OS X. On a tablet, users could bring their finger above the corner of a window to expand the small buttons that control minimizing, enlarging, and closing functions.

Despite the approval of the patent application, it remains unclear if or when Apple will integrate the technology into upcoming devices.
