A quick glance can say a lot, but sometimes its meaning can get lost in translation. For example, there's not a lot of difference between a dirty look and a, uh, dirty
look, but Yoichi Yamazaki and cohorts at the Tokyo Institute of Technology hope to quantify that (and many more) by creating a so-called Eye Robot. It's a pair of disembodied eyeballs that create expressions in concert with pink eyelids; a user views each expression and then indicates how it makes him or her feel. At this point it seems like something of a scatter-shot affair, throwing out expressions at random and seeing which elicit a reaction, but hopefully in the near future Yamazaki's metrics will help make the vacant gaze
of other bots a little less disconcerting.
