At the China Hi-Tech Fair, the hybrid motion gaming controller "i-dong" (AKA knock-off), developed by Taishan Online Technology Co Ltd, showcased its use on a PC and as an STB (set-top box) for playing games.
The i-dong consists of a sensor unit to be used with a display and a dedicated controller to be held by the user. The sensor unit is connected to a PC or an STB via USB and powered via it. Price US $220.
While presenting at the 2009 Korea Serious Games Festival I saw a ton of game controllers/remote controllers.
