We've certainly seen some clever methods
from one's mobile, but Vodafone's latest idea is quite the stroke of genius. Showcased at CeBIT, the Otello search engine simply uses images as input; in other words, handset owners just snap a picture of anything -- a landmark, DVD case, unidentified flying object, etc. -- and Otello then "returns information relevant to the picture to the mobile phone." Reportedly, Vodafone is expected to conduct a trial with German paper Bild in which readers can "find out more about specially-marked articles by photographing them with their mobile's camera and sending the image to [the aforementioned paper]." Unfortunately, the carrier is being tight-lipped with its plans for Otello beyond the trial, but if this stuff functions as advertised, we can't see it remaining a secret for long.
