Surprised!Apple has new technology, the use of LED lighting control iPhone from a distance
The United States patent and trademark office (office) on February 3, awarded the apple company (hereinafter referred to as the "apple"), a new patent, the technology allows apple users "distance" manipulation of the screen.
The patent technology called "close and multi-touch sensor detection and demodulation", patent number 9250734, through close sensor with traditional perception multi-touch screen coordinates, to manipulate user area expanded to the screen, so as to detect non-contact gestures.
To some extent, the patent technology with the apple on the iPhone 6 s introduced in 3 d Touch Touch pressure technology after some similar, but in the opposite direction.3 d measure users Touch down Touch, and the new 3 d suspended gestures patent measuring user action over the screen.
For a long time, the industry has been in the non-contact interaction, such as by cameras and other specific optical system for long-distance gesture.While apple the new patent technology is a kind of more suitable for the iPhone, MacBook solution and other portable devices.
Apple, very specifically, it is recommended to use infraredLEDAnd photoelectric diode, as iPhone used to detect the user's head of infrared sensing module from close range.Produced by the LED light on the user's fingers, return is captured by the photodiode.Through the deployment of multiple sensors, the system can detect suspended in the fingers, palms, and other objects above the screen.
Tech blog AppleInsider thinks, in the short term, apple is not the technology can be applied to the iPhone, and other equipment.Because the current 3 d Touch technology also only be applied to apple's own applications, many third-party application developers has yet to make full use of the 3 d Touch technology specialty, at this time to launch another developer will only make the new control technology even more confused.
An application for a patent for the technology is apple submitted in March 2015, the inventor for Steven hult spirit (Steven p. Hotelling) and Christopher carat (Christoph h. Krah).
