User Interfaces for Spatial Augmented Reality

This talk explores the current research in Spatial Augmented Reality (SAR). Instead of the users wearing or carrying the display such as for head mounted displays or handheld devices; SAR makes use of digital projectors to display perspectively correct graphical information onto physical objects. The key difference in SAR is that the display is separated from the users of the system. Because the displays are not associated with each user, SAR scales naturally up to groups of users, thus allowing for colloca
