According tomedia reports, Motorola Mobile filed a patent with the USPTO (U.S. Patent and Trademark Office) and WIPO (World Intellectual Property Office) in May 2018. The patent will allow the folding device side with a variety of touch sensors. The patent, called “Accumulated Sensors for Collapsible Devices,” was approved on November 21, local time.
It’s not hard to see from the patent images, it’s similar to the Motorola RAZR. The phone has the ability to fold horizontally, and when folded you can get a second smaller display.
According to the patent document description, the four sensors on each side of the device — two below the folding line. These touch sensors are used as virtual buttons that can be used either when folding a smartphone or when the device is expanded.
In addition, these sensors can recognize a variety of gestures including sliding motion. According to the file, the touch sensor can perform a total of 20 different functions and 20 different gestures.
When the device folds up, the sensor above the line is located right next to the sensor below the line, at which point the two touch sensors can be combined to achieve other functions. To do this, the device will have a so-called “cumulative sensor mode”.
Earlier this year, the company also filed a patent for the operation of its collapsible smartphone, which involves gesture movement of the display itself.
Motorola also sees motorola’s desire to provide an in-display fingerprint sensor for the collapsible smartphone. The current RAZR has a physical fingerprint scanner installed.
