3. 2005/05/25Virtual Reality Report3 Immersion-Physical ► Is it important? ► How can we accomplish it?

4. 2005/05/25Virtual Reality Report4 Immersion-Mental ► Key role in the experience ’ s fulfillment ► A mark of how successful the communication of a virtual world is. ► What is its advantage?

5. 2005/05/25Virtual Reality Report5 The Role of Realism in Immersion  Two schools of thought -First: [Astheimer et al.1994] -Second: [Slater and Usoh 1994] (Researchs that Psychologists already have done [Rothbaum et al.1996] )  Stereoscopic display
