Abstract

Augmenting the physical world using projection technologies or head-worn displays becomes increasingly popular in research and commercial applications. However, a common problem is interference between the physical surface’s texture and the projection. In this paper, we present FreeTop, a combined approach to finding areas suitable for projection, which considers multiple aspects influencing projection quality, like visual texture and physical surface structure. FreeTop can be used in stationary and mobile settings for locating free areas in arbitrary physical settings suitable for projective augmentation and touch interaction.
