However, these two patents are different from the hovering of the distance sensor in amber update, and the hovering interactive patent will be applied to touch screens.
The first is the application in text input. The patent of hovering interaction allows users to pause large specific letters and words during text input, which is more convenient for input, and can quickly move the cursor through hovering gestures. At the same time, this interactive mode can also be used in web browsing, and hovering with your finger can enlarge the display content of some web pages. On the other hand, applications operate devices mainly by hovering touch. When the user hovers over the icon, he can click it.
At the same time, it is also noted that Nokia's patent application seems to have been completed long ago, and the patent application uses the old Windows logo device framework. It can be seen that Nokia has completed the patent application in the era of Windows Phone 7, but unfortunately the application of this patent has not been seen on the current equipment.
At present, the devices that can use hover touch mainly include Samsung S4 and several Sony devices. In Meego era, N9 can also realize this function through software (with front camera), but this technology is still in the stage of gimmick.
Floating touch is mainly realized by running self-capacitance and mutual capacitance on capacitive touch screen at the same time. Mutual capacitance is used for normal touch sensing, including multi-touch. And the self-capacitance is used to detect the finger hovering above. Because the floating touch technology relies on self-capacitance, it is impossible to realize floating multi-touch, that is, when floating, the screen does not support multi-touch, and the screen can only realize multi-touch when touching.
However, it is still uncertain when Nokia will bring this technology to Lumia. Maybe it needs to be modified on the system side after it is merged into Microsoft.
