Mind-Reading Remote, Other CES Gizmos You Missed

This year's Consumer Electronics Show had the predictable high-tech TVs and other conventional items—but the 3,100 exhibitors also showed off some rather bizarre devices. A few highlights:

• Solowheel. An electric unicycle with no seat and footboards that allow riders to stand and lean in the direction they want to go. The 26-pound, $1,800 machine goes 10mph on its battery-powered motor, and has a 15- to 20-mile range.

• Haier Brain Wave. A mind-reading contraption that can control your TV...sort of. Users put the device on their heads, where it measures brain waves in order to move an onscreen character up or down. That's all it can do so far, but eventually it may be able to change channels. It's not selling outside China.
• Eye Asteroids. A video game whose joystick is your eye. Users stand before a screen showing asteroids; any asteroid a user gazes at gets shot with a laser. Swedish maker Tobii is selling it for $15,000, and hopes to integrate the technology into computers to replace the mouse.
