PrimeSense has been granted a patent by US Department of Patent & Trademarks. The patent description suggests that it can be used to control Mac by hand gestures. The patent has been granted and that means, the company can now implement it in the devices. However, we do not have much clarity over how long it might take for Apple to actually launch the new products with this technology.
PrimeSense has been a notable name in the sensor technology. This is the same company behind developing Kinect Sensor for XBox. Apple had acquired it in 2013. Earlier reports have indicated about PrimeSense involvement in developing Face ID, the revolutionary feature recently launched with Apple’s special 10th-anniversary product, iPhone X.
According to the data, we have until now, the new patent technology makes use of a TrueDepth camera in Mac and will allow detecting gestures within a range of 5 feet from the device.
The text, issued with the patent grant, throws some light over the use of gestures to control the mac
A method, including receiving, by a computer executing a non-tactile three dimensional (3D) user interface, a set of multiple 3D coordinates representing a gesture by a hand positioned within a field of view of a sensing device coupled to the computer, the gesture including a first motion in a first direction along a selected axis in space, followed by a second motion in a second direction, opposite to the first direction, along the selected axis. Upon detecting completion of the gesture, the non-tactile 3D user interface is transitioned from a first state to a second state.
Apple has been betting aggressively on implementing gestures and Face ID like features in its future devices. A number of reports have suggested Apple filing a patent to obtain a Face ID like patent for Mac. Also, a recent report suggested that Apple was working to launch a future generation of HomPod with Face ID unlock feature.
