The U.S. Patent and Trademark Office published an Apple patent for a method of generating and manipulating a 3-D object on a computing device, with the process controlled by special gestures made above a touchscreen’s surface.
Apple’s patent titled “Working with 3-D objects” is all about manipulating and generating 3-D objects using 3-D gesture inputs enabled by graphical interface.
It also describes about detecting the locations of finger with a combination of capacitive touch sensors and proximity sensors embedded in the display. By measuring the capacitance of a nearby finger,the capacitive sensors themselves can act as proximity sensors.
Apple’s 3-D object creation and manipulation patent was first filed for in 2012 and credits Nicholas V. King and Todd Benjamin as its inventors.
