at augmented world expo 2013, optinvent demonstrated a prototype of their ora see-through mobile ar display platform. the demonstrator included a monocular see-through display with the patented "flip-vu" feature allowing two positions for the virtual image. the display can be positioned directly in the wearer's field of vision or below it. one position is the "ar mode" whereby the image is directly superimposed on the wearers central field of vision; then by flipping the display down (mechanically), the wearer can have a "dashboard mode" whereby the virtual display is below the wearer's field of vision. this gives the possibility of having both true ar and a "glance at" capability in one device. a developer's version of the device running android 4.1 jelly bean called the ora-s including an sdk was said to be released soon and will include bluetooth and wi-fi connectivity, a nine-axis orientation sensor, a camera, a microphone, loudspeaker, and battery in the form of photochromic sunglasses.
