Glassless Augmented Display for Public Signage

International audienceThis project realizes spatial augmented realityin public. We developed Glassless Augmented Display(GAD) which can show multiple different images todifferent direction simultaneously. Spatial augmentedreality allows audiences to watch their preferred imagesand audios on public signage. It is a highly applicabletechnology configured by a consumer-based 4Kliquid crystal display, superdirective speakers, a lenticularlens, and a multi-view image synthesizer implementedin a Unity application. We also proposed anapplication for GAD, which is called Simultaneous SpatialShared Display (SSSD), which is implemented onGlassless Augmented Diaplay. SSSD enabled (1) simulmultiplexcontent display, (2) perspective correction, (3)without glasses and any sensing system, (4) directionalaudio for each content, and (5) attachable to conventional2D display. These are used to display various contents,such as sports games and concerts, according tothe movement of the audience
