With glass an increasingly popular material for architecture, companies are experimenting with ways to balance its ability to let light in with the need for a little privacy. Glass that tints itself on demand has cropped up in sunglasses and cars, and is beginning to creep into buildings with electrochromic windows. Now, Kinestral has unveiled a new system of smart-tinting glass called Halio, which can be adjusted manually or set up to switch automatically.
Kinestral claims that in its clear state, Halio is indistinguishable from ordinary glass, but when the sun is glaring on the TV or you need to change clothes, it can be tinted to just the right shade of gray. The tint can be manually controlled through a wall-mounted panel, a mobile app, or voice commands, or set to automatically adjust itself in response to triggers like the weather, time of day, or the sun’s position.
