I'M USING WIKITUDE World Browser to see virtual billboards, geotagged images and the locations of people on Twitter while looking through my phone perched on my car's dashboard. Wikitude puts Augmented Reality (AR) into my car. It overlays digital directions and aggregated location data on live video shot through my car's windows. It works best when pointed ahead but there's no reason a passenger wouldn't get accurate info by turning the cameraphone sideways and reading the AR world from there. I haven't tried driving by looking through the 4.3" viewfinder on the X10. I may wait until I can buy Wikitude Drive next month. It sells for $9 in the Android Market.
