I'm a physician, and this kind of stuff is medical shovelware. It will be sold to some poor hospital administrator somewhere who is not medically trained but who thinks that this sounds like a right easy solution to the problem of those non-English-speaking people who keep bumping up the delay times in the ER (a real problem in parts of the country that are just now seeing significant Hispanic influx, like much of the South and Midwest). Meanwhile, the doctors and nurses at the front line will find it ill-suited to what they actually need to accomplish. Flash cards work pretty well for most communication to rule out immediately life-threatening illnesses. After that, you really need a highly qualified translator. Maybe in five years, or a decade, machines will be at that point (although they'll be Google Translate's server farms, not some hand-held piece of junk), but they're not there yet, and it's wasteful and stupid to pretend that they are.
