Star Wars Lightsaber Battle Force (Plug and Play TV games)

To make the game work, you connect a 4-inch round "training droid" to your television's audio/video input plugs and then position the droid on top of your TV. The training droid contains the games and has an "electronic eye," which, through the use of infrared technology, detects the movements of a handheld lightsaber provided with the game. As kids slice the lightsaber through the air, their movements appear as blue streaks across the TV screen. The game runs off batteries that are housed in the training droid.
