Apple Patent Describes Laser Projected iPad Keyboard
Posted on February 2, 2013 by eli courey
An interesting patent application from Apple was recently published by the U.S. Patent and Trademark Office. The patent describes a laser projected keyboard for portable devices.
From Patently Apple:
The system may be used in combination with a projected control panel 115 (such as a keyboard, audio/video controls, and so on). The control panel 115 may be a light pattern projected from a light source onto a surface (e.g., table or desk), the control panel 115 may include different light shapes, colors, or the like for representing different inputs.
The system may determine the selection of a particular button or input of the control panel by determining the depth of a user’s finger, a stylus, or other input mechanism. The depth of the object may then be compared to a distance of each key or button of the control panel 115. Additionally, the system may provide for an enhanced projected control panel 115, which may allow for mobile electronic devices to decrease in size as a keyboard, or other input mechanism may be able to be projected larger than the mobile electronic device.
You may have already seen the concept video below, which demonstrates something similar to what Apple describes in the patent.
