Artist Eric Siu has created a wearable camera that blinds a user until they're touched by someone else. Touchy has two giant shutters that remain closed without human contact; once the helmet's sensors detect touch, the shutters spring open, Siu's eyes are illuminated, and the blindness is temporarily lifted until the connection is broken. If someone maintains contact for ten seconds, a photo is taken by the camera mounted on the front of Touchy, which is then displayed on a screen round the back. Words don't really do the project justice, but luckily Siu has directed a short film of Touchy in action.

With Touchy, Siu wants to highlight social anxiety, which he believes is caused by the increased reliance on communication mediums like Facebook and Twitter. He says that the helmet emulates the isolating experience of over-reliance on social networks, and turns the wearer into a social device. If you want to know more about the motivations behind the project, along with some photos of device prototypes and internals, you can read a full interview with Siu over on The Creators Project.
