With all the studies on therapeutic uses for Nintendo's Wiimote, a deaf school's innovative use of PlayStation Portables and the potential for Microsoft's Project Natal to make games accessible to players with disabilities thanks to its ability to recognize objects, voices, gestures and facial expressions, it's easy to think that motion-sensing technology is an unequivocal boon to players with disabilities everywhere. But is it? It's certainly easier for some people with disabilities to move an arm than to push a small button (or six). But what about those players with disabilities who are attracted to video games partly because pushing buttons allows them to do things they cannot otherwise do? Will the move toward motion control realism bar some players from their hobby?
Jennifer Allan writes in Motion Control and Disability that her mother was in a car accident 25 years ago and, as a result, has a lot of trouble swinging her arms quickly. Her mother is an avid gamer, but with the advent of the Wiimote, she's having a lot more difficulty playing games than she used to:
"She was watching me once play The Legend of Zelda: Ocarina of Time on the N64, and liked the look of it, so I thought I’d purchase Twilight Princess for the Wii. She loved [it], but there was just one big problem: the combat. She was great at everything else, loving the puzzle-solving elements and the exploration, but every time she got into a fight with more than one enemy, she needed me to do it for her to allow her to continue. This became very frustrating for both of us, and was certainly very demoralizing for her because she had to admit defeat, something that no disabled person ever wants to do."
When it comes to my own disabilities, Nintendo's Wiimote does some things well and others, not so much. My left side is 40 percent weaker than my right, partly because my brain isn't fully aware of where my left body parts actually are. Since those internal hardware drivers haven't been loaded (so to speak), I use external feedback to remind myself that I have a left side. Since my left hand is weak, it doesn't have as much motor control, but it can grip things—which means I like the way the Wii's nunchuck attachment fills the whole inside of my hand.
But I also have trouble learning how to do movements of various kinds. This was mostly a problem in gym class, but it comes into play using the Wiimote as well. In particular, fending off Drackies in Dragon Quest: Swords is...awkward. Fighting enemies is accomplished by swinging the Wiimote like a sword, and I haven't mastered the art of slashing vertically just yet. It helps to remember that with the Wiimote more movement is not necessarily better; little flicks of my wrist are better understood than grand sweeps of my arm.
Nintendo's Demo Play feature could help some players with disabilities over motion-sensing hurdles. Also, some Wii games have multiple control schemes, but as Jennifer points out, expecting all developers to design control schemes for the Wiimote, the GameCube controller and the Classic controller is problematic: "[T]hat will increase development times and costs to the point where it’s just not practical." Perhaps some sort of development library would help here—something that streamlines or even semi-automates control-mapping. How—or if—such a thing would work, I have no idea.
As motion control becomes an increasingly integral part of video games, I hope developers will find more and better ways to use it. I also hope they know when not to use it, or keep alternatives in mind. It would be a shame to close the medium for some players while opening it up for others.
