I've already been thinking about this in my first conceptual speculation of the Revolution's controller. I was, and still sorta am, under this notion that Nintendo's next system will have multiple controllers/control interfaces. I had the idea of two "main" controllers...a conventional controller for ports, BC & traditional games and another for Nintendo's "revolutionary" controls. I couldn't really "sell" the idea at GAF so I made this
"Nintendo Speculation Page" on my site. Now I have a newer concept now. Basically instead of two "main" controllers I decided to meld the idea's together as best as I could in this doodle. Formerly called The "GameWand" now I call this controller interface concept The "GameGrip"...
My "GameGrip" Conceptual Features:
--Both GameGrip's Feature:
-Analog Sticks with digital clicks
-Analog Triggers with digital clicks
-Toggle Wheels with digital clicks
-Full Gyro Motion Control
-On/Off Switches
-WaveBird Wireless
-Rumble
-Zapper Light Sensor Lightguns
-Rechargable Lithium Ion Batteries
-Base Button (at the butt of the grips)
--Left GameGrip Features:
-Touch Screen
-On-Screen Button
-Built-In Mic
-Headset Plug
--Right GameGrip Features:
-4 Color-Coded Face Button
-Sensory "Feel" Button
-Start & Select Buttons
-Retractable Stylus Tip (to use with touch screen on left grip)
This control scheme allows for conventional gaming (there's plenty of buttons/functions to map out button layouts from ports from other systems) as well as the new types of gaming (built-in mic, headset jack, touch screen, lightgun, gyro motion control, etc.) and my big idea (what I think the "revolutionary" feature is): the sensory "Feel" button! With this set-up you could be playing a "normal" game and then all the sudden switch to motion control (wether it be tilting, aiming, swinging, steering, piloting, etc.) and/or switch to using the touch screen ALL on the fly 'cos you don't have to switch controllers as all these methods of control are already in your hands. There could even be lot's of games that could use just one "GameGrip" too. Another feature I've added is a base button at the butt of each grip...you could hold this base button down on a table and with the gyro motion control use it as an old fasioned joystick...or in a shooting game where you're using the lightgun sensors you can smack the base button as if you were reloading a handgun...or push the base button down firmly next to you and use the gyration control as if you were really shifting gears in a racing game. Another feature I thought of is a center peice that not only can be used for corded play and recharge the batteries, but also holds the two seperate GameGrip's together (at adjustable angles too) for that "normal" controller feel as I know some people wouldn't like the idea of holding two seperate units for some games. I think I made the controller very ergonomic for switching between playing method's and for using the full range of gyro motion control as well (imagine holding these as if you were putting up your dukes in a boxing game and, since they're wireless, actually shadow-boxing against opponant's in the game).
But my crowning feature is the sensory "Feel" button. It came to me after thinking about a recent rumor wich said something about: "touching is good, but FEELING is better"! To me, when you use the Nintendo DS's touch screen you're touching the game, but to FEEL something I believe that means the game is touching you back! I'm not suggesting that the controller will change shape and grab you, but giving the player a new sensation thru a button would still be really cool. How? They have electronic brail machines that can help blind people read regular script. But instead of this sensory "Feel" button being used to give players brail, it could give symbols, textures...game makers could even animate the button to give you sensations of water or sand or something moving. You could use this in a game for solving puzzles, searching for clues, telling where you're at or where to go, hell anything you can imagine. I gave alot of examples in the past on GAF when I had the notion for this sensory "Feel" button, but for now I think you get the idea. To note, as far as I know those electronic brail machines use tiny rubber fibers that change length to give the feeling of brail so...I made it to where you could remove the "skin" of this sensory button and clean it just in case. I think there's LOT'S of evidence to support this idea of a feeling button and even a more recent rumor (Nintendo 21's "rubable sensory" control) supports this idea as well.
