This wearable device lets you control objects by simply looking at them

Designed with astronauts in mind, the Eye of Horus is an open-source platform that lets wearers interact with any device by just looking at it. 

In recent months, we’ve seen quite a few 3D printing advancements stem from the aerospace industry, most notably Made In Space’s efforts to bring additive manufacturing into orbit as well as Rocket Lab’s battery-powered rocket engine destined for blast off. Now, a new project — which was created as part the 2015 International Space Apps Challenge — has employed 3D printers to help NASA engineers and astronauts safely complete tasks at hand.


While in space, engineers and astronauts are often forced to abruptly stop an activity to operate computers or some other tools, which could result in a loss of time that could ultimately jeopardize a mission. In an effort to solve this conundrum, a team from the Spain-based Makeroni incubator has set out to create a game-changing wearable that would enable these researchers to inteact with objects by simply looking at them. And adding to the impressiveness of the project, it was built in just two days.

Eye of Horus is a 3D-printed, open-source platform that allows a user to control devices via sight. The gadget in focus is identified using light beacons (similar to LiFi technology), which emit various frequency pulses for each device (whether that’s a PC, camera, TV or microwave). A frontal camera detects this light, differentiates and wirelessly communicates with the objects as the wearer glances at them.


As you can imagine, not only would this provide tremendous assistance to those in zero-G, but could be applied in a number of real world settings — particularly assisting those with mobility problems, drivers on the road who otherwise would have to take their hand of the wheel to interact with a device and gamers looking for an eye-controlled mouse.

Aside from its printed circuit board and software components, the Eye of Horus was created entirely by using 3D printing. Inside a custom enclosure lie a serial bluetooth 4.0 BLE Module, a relay control module, an infrared LED and n an Arduino Pro Mini (ATmega328). Meanwhile, the software is divided in two blocks: a server program (VoCore) running in the Eye of Horus and client in a laptop computer.

So what does the future hold for this incredible device? Its creators have their sights set on continuing the development of their eye-tracking devices and perhaps even a Kickstarter launch in the coming months. In the meantime, you can read up on their entire project here.
