Researchers from the University of Carnegie Mellon (USA) presented the first of its kind "smart" watches, which turn the user's hand into a touch screen.
This is reported by The Verge.
In the prototype LumiWatch prototype developed by the scientists there is no customary screen: instead of it on the side of the gadget is installed a small projector, as well as infrared sensors.
The clock projects the interactive surface onto the person's hand, allowing him to control the virtual display. Combining the readings of the sensors, the device can accurately determine the position of the finger on the hand.
In the video, demonstrating the work of the clock, you can see how the user drags his finger on the left hand to unlock the device, and then displays the time and available applications.
The clock can project an image of 40 square centimeters. As noted by the developers, this is almost five times the interface of ordinary "smart" hours.

The new device consists of a motherboard, a battery, a projector, a depth sensor and a metal case. The projector uses the radiation of three lasers (red, blue and green).
LumiWatch also has a finger tracking feature.
In addition, the watch is equipped with a central quad-core Qualcomm processor, 768 megabytes of RAM, 4 GB of flash memory, and a 740 mAh lithium-ion battery. The device is running Android 5.1.
As the researchers note, with constant projection, the clock worked on one charge for more than an hour.
At the same time, developers recognize the presence of problems: in particular, projecting an interactive surface onto the hand is a difficult task, since the hand is not flat. Because of this, the operation of such a "display" may cause interruptions.
The developers believe that in the case of the sale of the clock would cost about 600 dollars.
