Apple Reveals Future of Display Tech With Interactive 3-D Image Patent
A recently published Apple (NASDAQ:AAPL) patent outlined an interactive 3-D display technology that could one day be used in the Cupertino-based company’s devices, reports Apple Insider. In a patent titled “Interactive Three-Dimensional Display System,” Apple described a technology that would allow users to control and manipulate a three-dimensional image that has been projected in mid-air above a display structure.
In the patent background information, Apple noted that unlike most other conventional of 3-D display systems, its system does not require “special viewing equipment such as glasses, goggles, helmets, or other viewing aids in order to view the 3D image.” Apple pointed out that this viewing equipment tends to be “cumbersome and undesirable.” While autostereoscopic display technologies can produce 3-D images that don’t require special viewing equipment, these systems have other disadvantages. For example, parallax display systems only produce a 3-D image when viewed from a particular location and volumetric display systems have a tendency to produce distorted images that can strain users’ eyes.
On the other hand, Apple’s proposed 3-D display system would produce clear 3-D images that could be seen from various locations. Users would also be able to interact with the projected image through the use of “a visible light laser, an ultraviolet (UV) laser, an X-ray laser, or other suitable type of laser.” When the laser strikes an external object such as the user’s finger or hand, the system determines the location and movement of the object using light-based sensors. However, Apple also noted that the 3-D display system does not have to include the interactive feature.
