IEEE, and Steven Feiner, Member, IEEE

Display Technology

Projection-Based Displays

Display graphical information directly on real objects or

even daily surfaces in everyday life.

Interaction Techniques

Tangible AR

Futher blend the real and virtual world by giving the

physical feel to digital information

Interaction Techniques

Collaborative AR interface

Use a set of multiple displays to support sharing and

interaction between people
