With the miniaturization of projection technology, the integration of tiny projection units into mobile devices is no longer fiction; therefore, such integrated projectors in mobile devices could make mobile projection ubiquitous. These phones will have the ability to project large-scale information onto any surfaces in the real world, and by doing so, the interaction space of the mobile device can be considerably expanded. In addition, physical objects in the environment can be augmented with…

A semi-automatic realtime calibration technique for a handheld projector
TLDR
A semi-automatic realtime calibration technique for a handheld projector that always keeps a shape of a projected screen rectangular on a specified projection surface, while a user continuously changes his standing position or the pose of the projector.
Impact of item density on magic lens interactions
TLDR
It is found that visual context is most effective for sparse item distributions and the performance benefit decreases with increasing density, and subjective feedback indicates that participants generally prefer visual context over the lack of external visual context.
