A new patent from Huawei has revealed yet another smartphone that sports a rollable display. However, the aspect that sets it apart from the ones we have covered previously is the support for gesture controls.

According to a LetsGoDigital report, the Chinese tech giant filed a patent with the World Intellectual Property Organization (WIPO) for a new method for a ‘controllable foldable display with haptic and sound effect.’ While we had reported on a recent patent that described a rollable display that wrapped around what appeared to be a futuristic Mate series device, this patent talks about a system that describes how this rollable screen can be rolled in and out.

The patent outlines a method that allows users to operate this rolling out or extending panel mechanism, through the use of touch movements (or hand gestures on the screen), which Huawei has subbed as “freehand gesture control.” To control the extendable display, a virtual slider will be displayed on the screen that lets users begin the rollout process. This system will also be paired with a haptic feedback system and a sound effect as well. Furthermore, the rollable smartphone’s support for freehand gesture control will be powered by a camera and/or a motion sensor.

HuaweiThrough this, the user can simply swipe right above the display to have it roll out and extend while swiping left would have the screen retract back to its original position. But this is just scratching the surface, as Huawei intends to allow users to even control the speed at which the display rolls out. So to achieve varying speeds as per user requirements, the brand plans on use a system that involves an ‘X’ number of the users’ fingers in the air. In simpler terms, the sensor recognizes two, three, four, or even five fingers and adjusts its speed accordingly.
