The Glyph is a mobile head-mounted display that doubles as a pair of headphones. It reflects 720p video directly to your retinas. It uses an HDMI input and lasts up to 3h per charge. Note that the Kickstarter reward is a beta unit.
Instead of slapping an add-on camera onto headgear, the iON is an 8mp/1080p HD camera built into a slick pair of impact and fog-resistant goggles. Its controls work through thick gloves too.
