In Cupertino, the engineers of the Apple company are constantly working on the development of new technologies and today I have for you one that has a purpose to improve the quality of the screens implemented in iDevices. Apple aims to develop a new screen model that optimizes its quality depending on the environment and the user's position. The new screen designed by Apple uses sensors from iDevices to perceive the ambient light and the positioning of the user in order to change its brightness or to generate dynamic shadows on the content, all with the idea of improving the quality of images offered to users.
Apple's invention is about the use of various position sensors, eg, a compass, a Micro-Electro-Mechanical Systems (MEMS) accelerometer, a GPS module, and a MEMS gyrometer, to infer a 3D frame of reference (which may be a non -inertial frame of reference) for a personal electronic device, eg, a hand-held device such as a mobile phone. Use of these position sensors could provide a true Frenet frame for the device, ie, X- and Y- vectors for the display, and also a Z-vector that points perpendicularly to the display. In fact, with various inertial clues from an accelerometer, gyrometer, and other instruments that report their states in real time, it is possible to track the Frenet frame of the device in real time, thus providing a continuous 3D frame of reference for the hand - handheld device.
Dynamic shadows could be displayed either to put the content in perspective or to highlight only the content that the user is looking at, so we are talking about the implementation of sensors capable of calculating the position of the eyes and the content that the user is focusing on. The technology of the Apple company can be used both in iPhones and in iPad tablets or even laptops, but it seems to be taken out of a science fiction film and is still far from being implemented in a device, although at CES we saw a Windows 8 controlled using only your eyes.
Once the continuous frame of reference of the device is known, the techniques that will be disclosed here could then either infer the position of the user's eyes, or calculate the position of the user's eyes directly by using a front-facing camera. With the position of the user's eyes and a continuous 3D frame-of-reference for the display, more realistic virtual 3D depictions of the objects on the device's display may be created and interacted with.
