What is missing from motion-controlled shooting games

When I got my Wii way back when it first came out in November of 2006 I was really excited for the new gameplay possibilities it would provide. In particular, I believed that shooters would finally be playable on consoles. No offense to anyone that exclusively plays shooters on consoles, but a mouse just provides much better accuracy and control than a thumb-stick ever will be able to. With the Wii remote, you can just point at the screen and pull a trigger to fire, much like gun-wielding arcade games.

In order to try out the motion-controlled shooting experience, I got a game called Elebits. The aiming at the screen works well, and the player quickly becomes accustomed to pointing to get the cursor to move. The one big downfall of this targeting scheme comes when the player needs to change the direction of the camera. The only way to move the camera is to move the pointer to the edge of the screen and wait there until the camera has moved far enough and then return the pointer to the center of the screen. This method of controlling the camera is just as bad as using a joystick, and in fact a little bit worse. For instance, if you move the cursor just a little bit past the edge of the screen and leave the screen entirely, the sensor no longer knows which direction to turn, so it either turns the wrong way or doesn't turn at all. Maybe that's why all the shooting games in arcades are rail shooter (a game where the camera control is scripted, and the action is always where the camera is looking). Unless something is done to improve the current state of motion-controls for consoles (and most arcade games), rail shooters are the best kind of motion-controlled shooters we will have.

The way I would implement a motion-controlled shooter to make the controls non-frustrating and intuitive would require hardware that is more expensive and perhaps less practical to have in one's living room. Most importantly, the player would need to have a surround display system. I mean that a set of displays, or one large, curved display, would need to be placed around the player to allow for a 360 degree view at all times. The player could then point the wand/gun/whatever in any direction and use a joystick to move relative to that pointing direction. The result would be an intuitive, accurate, and easy to control shooter with motion controls. The only downside is that the display technology is much more expensive than people are willing to pay. One might also want more displays to look up and down in addition to the horizontal directions.
