Recently, the contents of the U.S. Trademarks and Patent Office again showed that Apple is indeed interested in the frame touch operation mode.
The document shows that Apple will use the same gripping operation in the frame touch operation. The gripping pressure channel through the border is not used to distinguish different operation modes. It is similar to the Edge Sense design proposed by HTC. As Apple already applied for this in 2013, Technical patents, therefore formally not plagiarism HTC.
According to the related patent technology description numbered 20180164166, Apple plans to apply the 3D Touch multi-gravity channel press function to the fuselage frame, and can correspond to different operating functions for different pressing positions, and can also be applied to metal or plastic housings.
If Apple adopts this technology patent design in the next new machine, it may enable the iPhone to have more meta-modes of operation, and at the same time, it can further simplify the edge buttons, so that the waterproof effect of the mobile phone will be greatly improved.
