interaction design i think is very interesting market and i think has only just begone to be tapped into with wii and xboxs kinect there still so much that is yet to be improved on so far i think the wii could bring a hole new level to gaming in general at the moment its only real used for family entertainment and younger genretion wii sport games a such but i think the capabilities could be used for alot more not just serious gaming for example use for the army simulators it essence like an arcade game when you hold the gun as the controller but the environment of the game projected around you training soilders pilots for real time warfare but i think one of the biggest obsticules would be movement in the game the game would you have to be in an empty room to move around without hitting anything you wouldn't even have to have a controller already kinect 2 has been developed to take in alot more depth an individual fingers movement so the flick of your finger could fire a weopon it wont be long before its even more in depth. the wii and kinect have opened up a massive market for improvement and space to reinvent gaming. so far the consoles can sense where your are and allow you thinks run jump do activates as an avatar i think it will be really interesting when you as player can feel the game for example a console where you put a helmet on an gloves and run and jump an get shot at feel vibrations or pressure on your gloves as you play. 3d technology has been rising as well and has become alot more exsesable at the cinemar 3d games, seeing a film around you and popping out at you i don't think it will be long before both are merged together 3d goggles with interactive movements. i think the rise of the wii has brought a big new market for games i think the only downfall to interactive games is that when alot of people play video games they lie to sit at home and chill out and play them not run around in your living room like a gym alot prefer sitting on a sofa twiddling there thumbs me included an getting emersed in the story line but with the market it brings alot more active to people to buying games which is proaply a good think for people in general and the gaming industry on a hole .
