Aside from how Wii figures out where you are in space, how does it figure out what direction you are facing?
How many times have we used a GC controller in say Mario Kart; we look at the screen but hold our controller casually in our laps - it could be pointing at the screen but it could also be pointing at the floor - or the wall. Now imagine Mario Kart on Wii (assume it uses controls similar to Excite Truck) We tilt right to turn right and tilt left to turn left. But what if we are sitting to the side of the screen and tilting right means that we tilt away from or towards the screen? This might not have a huge effect on Mario Kart because it could rely on the gyroscopes alone, but what about a game like tennis where the position of the wiimote in space becomes an integral part of the controls? Can Wii tell that I am trying to use my forehand even if I am swinging at an angle that is not perpendicular to the sensor bar. And if it does interpret that has a forehand, then how do I control the direction of my shots?
I ask this long question because all of the pictures on Nintendo's website show single players right infront of the screen, or groups of players bunched up together(so that they are right in front of the screen) What if I want to spread out with my friends because we dont wanna run into eachother or catch a wiimote to the jaw after an intense backhand or homerun cut? Is this possible? Or will there be serious calibration errors?
