Rather, TV, computer or other device observes the user and the user's environment, and makes sense of what they see. With the ease that an officer can direct traffic in a busy intersection with a few natural gestures, we will be able to convey our intention to our units, Spare predicted.
The real impact of 3D interfaces such as Gesture-controlled TVs are that they will make a wide range of complex services readily available and accessible through a very natural user experience. The key, enabling natural interface technology, is a mass-market, 3D vision. Only when appliances can easily recognize, in real-time, fine-grained features of a scene, in any light conditions and against any background, can subtleties like hand gestures ̵
Apple has also filed various patents involving 3D interfaces, such as patent number 20140055483 for a "computer user interface and method." According to patent info and graphics, it will involve a Mac screen with sensors built into all sides of the screen frame. The sensors recognized hand movements. The gestures can be used to scroll, select, zoom and more.
The sensors would also adjust the screen brightness and change the screen interface depending on how close you are to your Mac. For example, the size and / or content of the information displayed by the computer may be altered or controlled.
