What is Cybertherapy?
CyberTherapy –Also known as E-Therapy or Virtual Reality treatment
The use of computers as tools to enable and/or enhance the provision of therapeutic services.
As a therapeutic tool, the computer serves two functions :
communication device –“… accesses new ways of interacting at a distance…”
simulation device -“… creates virtual realities”
Abraham Wolf (2003)

And Virtual reality …. ?
“Reality is merely an illusion ... It is just a very persistent one”

Rationale:
To be useful adjuncts or alternatives in the treatment of phobias, VR must invoke emotional reactions that are comparable to in vivoreactions (or at least positioned between those for imagined and real situations). Wiederhold, Mendoza, Nakatani, Bullinger, & Wiederhold, 2005 IN Wiederhold (2005)Study of blood sampling and injection phobiasnon-phobic participants had physiological and emotional responsesduring exposure to VR hospital clinic images that were comparable to those in real environments

Pros and Cons
Using Virtual Reality for Therapy
not a substitute - supportive method for clinical psychology can increase treatment efficiency (shorter duration) easy distribution and delivery of standardised programmes enabling for some clients permits experiences that may be otherwise unattainable increasingly economical (some initial outlay) research is easily and exactly replicable can provide a controlled, safe environment reduces travel demands on clients/therapists can be made more collaborative ....

Goal: VR based system for the treatment of various disorders
Affordable setup (low-cost components) with sufficient quality
Use of existing technologies and combine them (here VR approach with computer-mediated communication)
Joint work of Psychology and Information Science Phases / Options:
1. collaborative setting therapist + client as a first working prototype
2. group work (1 therapist – many clients), extendable to even more therapists or other experts
3. distant therapy (e.g. rural areas)4. Different Technologies (projection, head-mounted

Conclusion and Discussion
proliferation of assistive technology is inevitable clinical applications are feasible and a current
reality interdisciplinary contributions (eg. Psychology,
Information and Computer Science, Design) collaboration is possible within NZ and
internationally and there are opportunities for international linkages
network of VR researchers/practitioners in NZ is desirable
exploring future opportunities need to develop ethical and safety principles in
parallel with development of technology
