A group of researchers at Waterloo Labs in Texas have devised a eye-popping way to play videogames. Special sensors attached to their faces allowed the researchers to direct the movements of an on-screen character by shifting their eyeballs — urging Mario from the much-beloved 1980s videogame Super Mario Bros., for example, to race off to the right simply by looking in that direction. As demonstrated in the clip below, a glance upward makes Mario jump. "What's next," asks Philip Wong at CNet Asia. Twitching your toes to play racing games? "I'll settle for keyboard and mouse," thanks. Even if hardcore gamers see no value in this, says Luke Plunkett at Kotaku, it could be a real breakthrough for disabled players with limited "hand or finger control."
