Developed by an Israeli startup of the same name, Bzigo incorporates an infrared LED, an HD wide-angle infrared camera, and a microprocessor. Utilizing computer vision algorithms running on the latter, it's reportedly able to differentiate between mosquitos and other pixel-sized airborne objects (such as dust particles) based on their movement patterns. It even works in the dark.
Once Bzigo detects that a mosquito is in the room, it notifies the user via an app on their smartphone. To help them see where the insect is, the device laser-projects a box around it, whenever it stops moving. It's then up to the user to do the actually swatting, although a future version of the product may be able to "autonomously eliminate" mosquitoes after they've been detected.
