In short this task should be based more around use of physical interaction with the non-physical game. With games now choosing to use less of a control pad or in some cases no control pad at all, its hard to see where the future of games are going to.
But I will also talk about user interfaces here and there along the way, keep your panties on.
Lets start at the beginning. The joystick allowed 8 drirections of movment, with 1 to 3 comand buttons, the simple logic of this was often explained on the conroler and had a direct and rather obvious reaction in the game. A similar trend continued through out the 80s and early 90. This was until the analog joystick appeared on the nintendo’s N64. This appeared due to the use of 3d technology in games, now with consoles becoming more powerful it enabled the controller to move through 3 dimentional space, instead of the predeceasing 2D space. However this was more obviouse with the Sony PlayStation analog controller , the Sony playstation took full advantage of its analog controller, as you could use the left analog to move that character, and the right to rotate the camera. This has been a primary function of modern controlers. The 2d style of controlers effected the user interface of games
However in the past 5 or so years, time has a way of slipping by un-notice, motion sensors has became the fad amongst game developers. Nintendo and Sony use similar motion capture technology, not to mention dule-stick like controlers, which bare close resemblance to each other. The xbox connect had decided to go one step further and remove the controller all together, and instead using the motion capture to almost have the player in the game, being more physical. And motion capture and user interfaces will probably bring us closer to that, matrix style computers, moving each window out of the way with your hands, crazy to think about, but if there is the will, there is the way.
And if you notice, this new age of 3d and glimmer glammer has risen to new crazy, sleek user interfaces?
Remember Nintendo’s Virtual boy? The first real taste of 3D, even thought it was terrible and failed as a product. A decade later, Nintendo has came back into 3d with the Nintendo 3DS, a hand held 3D console that requires no additional equipment, only a slider is needed to cause the 3D effect. Its pretty interesting to think about, the change between the 2d into the relms of 3D. Yeah, Im dont know anymore.
