Yahoo and Total Immersion teamed to provide an interactive  Kiosk at the "Yahoo Fancouver" exhibit. 

It takes a three-panelled screen with sections for news, weather and medal counts.  Through facial tracking, the AR software will place various hats or accessories like sunglasses and umbrellas for the weather section; press hats for the news section.
