Effect of an external viewpoint on therapist performance in virtual reality exposure therapy
Martijn J. Schuemie · 2002
In Virtual Reality Exposure Therapy, therapist are usually only supplied with the same viewpoint of the Virtual Enviroment (VE) as the patient. This paper investigates the effect of an external viewpoint on the performance of therapists in a VE. Results show that even though this second viewpoint increases the precision with which the therapist can align real and virtual objects, subjects navigate through the VE in a less efficient manner.
