According to foreign media reports, Apple this week adopted a new patent, the patent shows Apple is developing a support ForceTouch Mac keyboard touch technology.

The patent by the US Patent and Trademark Office approach, patent No. No.9178509, the patent entitled “ultra-low key way Keyboard”, the patent Apple in September 2012 filed the first patent inventors Jeffrey T.Bernstein. The keyboard principle described in this patent is similar to Apple’s prior Force Touch touch technology, but a lot of large size. Under each physical button is equipped a pressure sensor, a pressure sensor is located beneath the key cap, the actuator can generate tactile feedback.

Apple patent describes an integrated similar Force Touch touch technology, without the use of any full-size QWERTY keyboard key axis. This patented keyboard After removing the mechanical key axis, can reduce the height of the keyboard a few millimeters, the future wants to help Apple build size thinner MacBook products.

The best hardware input conditions include a resistive sensor, strain gauge and capacitive sensors, and also includes other components can detect the user presses the button, the intensity, and sends a signal to the computer’s processor. At the same time, the sensor can detect a slight change in the distance, and set the system to provide a high platform to get different input levels.

The other key component is the actuator, can achieve transmission piezoelectric material, when the bottom of the piezoelectric material to obtain mechanical power can be turned into a mechanical strain from the application field. The use of these unique electrical characteristics, ForceTouch meet similar needs.

In the process of entering, by pressing the keyboard’s different specific signal intensity through output, including embedded pressure sensor. In determining the user presses the intensity, the keyboard controller will receive the signal and further processing. Then the keyboard will simulate a user clicks through different intensity of different mechanical keyboard feel, and cooperate with the transmission system.

For the detection of different size pressing efforts, coupled with the Apple keyboard, and supporting software to make a key corresponding to a variety of operations. For example, applying the key “A” force the size of the first one, will enter the “A”, the second the size of the force would trigger a system command or other functions. This process is similar to the 3D Touch technology on the iPhone 6s, allowing the user to achieve the Preview, Quick Start and other functions through different intensity.

It is unclear whether Apple will launch today, based on the patented Force Touch keyboard, but do not find evidence of Apple in the development of related hardware and software.
