Two University of Washington undergraduates have won a $10,000 Lemelson-MIT Student Prize for gloves that can translate sign language into text or speech. The Lemelson-MIT Student Prize is a nationwide search for the most inventive undergraduate and graduate students. This year, UW sophomores Navid Azodi and Thomas Pryor - who are studying business administration and aeronautics and astronautics engineering, respectively - won the "Use It" undergraduate category that recognizes technology-based inventions to improve consumer devices. Their invention, "SignAloud," is a pair of gloves that can recognize hand gestures that correspond to words and phrases in American Sign Language. Each glove contains sensors that record hand position and movement and send data wirelessly via Bluetooth to a central computer. The computer looks at the gesture data through various sequential statistical regressions, similar to a neural network. If the data match a gesture, then the associated word or phrase is spoken through a speaker.

A few weeks ago, after I said goodbye to a friend who was moving across the country, I texted her an emoji of a crying face. She replied with an image of chick with its arms outstretched. This exchange might have been heartfelt. It could have been ironic.

Use of emoticons varies by geography, age, gender, and social class-just like dialects or regional accents. Friend groups fall into the habit of using certain emoticons, just as they develop their own slang. Emoji have undoubtedly changed the way we text, Gchat, and tweet-but are they changing language itself? While emoji are more popular than ever, the idea behind them is actually quite old. "There's an old utopian ideal that we could create a kind of a universal pictorial language," says linguist Ben Zimmer. Emoji could even mark a return (regression?) to a more pictographic script. However, Ben Zimmer suggests that emoji help convey tone and emotion and enrich written language.

This article discusses both emoji use, and emoji effects in language and expression. The vast majority of web users use or have used emojis, and the emojis that we use can yield information about us such as our general age and interests. Furthermore, emojis may be a form of language simplification and a return to pictogram communications.
