U-Force

The U-Force is a game controller made by Broderbund for the Nintendo Entertainment System. Two IR panels are used to detect hand movement.

A print advertisement from about 1989 says:

Introducing U-FORCE, the revolutionary controller for your Nintendo Entertainment System. So hot, no one can touch it. Now you can feel the power without touching a thing. It's U-FORCE from Broderbund - the first and only video game controller that, without touching anything, electronically senses your every move, and reacts. There's nothing to hold, nothing to jump on, nothing to wear, U-FORCE creates a power field that responds to your every command--making you the controller. It's the most amazing accessory in video game history - and it will change the way you play video games forever. It's the challenge of the future. U-FORCE. Now nothing comes between you and the game.

Reception

IGN editor Craig Harris said the U-Force is the eighth worst video game controller. MSN editor Duncan Jefferies said it is the second worst peripheral, saying "Second only to the Sega Activator in terms of all-out crappiness, the U-Force also used infrared sensors to create a truly nightmarish controller...'Don’t Touch' said the adverts for the device, in a rare example of an advertising campaign that got it spot on."
