The CenWatch might be useful if you're sick of operating your devices with a dull old remote. Using basic hand movements in midair, this smartwatch can identify the bottom of your hand and provide you with a variety of commands.

The CenWatch is being produced by the same-named Hong Kong firm and is presently being offered on Kickstarter. Indeed, there is a 368 x 448 AMOLED screen on the gadget that shows the date, time, and battery level, reports NewAtlas.

What sets it apart is the device’s LiDAR (light detection and ranging) scanner.

This device, which is worn on the underside of the wrist, employs near-infrared lasers to measure the three-dimensional spatial position of each of the five fingers (in relation to the wrist) as they are moved to execute various preset movements. It is said to be accurate to within 1 mm of resolution.

Additionally, there is an IMU (inertial measuring unit) that measures the wrist's three-dimensional spatial location in relation to the body.

Simply bring your arm out in front of your body at a 90-degree angle, as though you were checking the time, to activate the CenWatch. The LiDAR and IMU data are then processed in real time by an inbuilt HelioG99 8-core CPU, which determines which orders the user is issuing.

These commands are sent by Bluetooth up to 196 feet (60 meters) to a partnered Android, iOS, Windows, Mac, or Linux device. Other devices such as smart TVs can also be controlled via IFTTT (If This Then That) technology.

According to the designers, the CenWatch is particularly tailored to use with AR or VR glasses, as it allows users to perform actions in 3D worlds via 3D gestures. In addition, the technology may eventually enable considerably slimmer and more energy-efficient glasses by relocating the control circuitry from the glasses to the watch.

All of the standard interface operations, including tapping, clicking, swiping, scrolling, and even typing on a virtual keyboard, are available to users. However, you may also use hand movements in midair to write or draw on the projected display while creating PowerPoint-style presentations.

The device weighs 92 grams (3.25 ounces), and the 1,700-mAh lithium-ion battery is said to last up to 10 hours on a single charge.
A pledge of US$299 will buy you a CenWatch, assuming it goes into production. $499 is the anticipated retail price.
