These pilot data provide initial support for the use of acute dosing of DCS as an adjunct to exposure-based psychotherapy to accelerate the associative learning processes that contribute to correcting psychopathology.
Real-time, continuous level of detail rendering of height fields

- Computer ScienceSIGGRAPH
- 1 August 1996
An algorithm for real-time level of detail reduction and display of high-complexity polygonal surface data that has been implemented for approximating and rendering digital terrain models and other height fields, and consistently performs at interactive frame rates with high image quality.
An evaluation of techniques for grabbing and manipulating remote objects in immersive virtual environments
This work presents implementations and discussion of six techniques which allow manipulation of remote objects which provide distinct advantages in terms of ease of use and efficiency because they consider the tasks of grabbing and manipulation separately.
Travel in immersive virtual environments: an evaluation of viewpoint motion control techniques

- 1 March 1997
Results indicate that "pointing" techniques are advantageous relative to "gaze-directed" steering techniques for a relative motion task, and that motion techniques which instantly teleport users to new locations are correlated with increased user disorientation.
Evaluation of the CyberGlove as a whole-hand input device
An experimental study is conducted that investigated the level of sensitivity of the sensors, their performance in recognizing angles, and factors that affected accuracy of recognition of flexion measurements of the CyberGlove model CG1801 whole-hand input device.
Testbed Evaluation of Virtual Environment Interaction Techniques
- D. Bowman, Donald B. Johnson, L. Hodges
- Computer SciencePresence: Teleoperators & Virtual Environments
- 20 December 1999
This paper presents a systematic approach, testbed evaluation, for the assessment of interaction techniques for VEs, and presents two testbed experiments, covering techniques for the common VE tasks of travel and object selection/manipulation.
A pilot and feasibility study of virtual reality as a distraction for children with cancer.

- 1 October 2004
It is suggested that virtual reality may be a useful tool for distraction during painful medical procedures, but further studies are needed to test potential efficacy and feasibility during other, more distressing medical procedures with larger sample sizes.

The results of an open clinical trial using VRE to treat Vietnam combat veterans who have DSM-IV PTSD hold promise for treating PTSD in Vietnam veterans.
Formalizing the Design, Evaluation, and Application of Interaction Techniques for Immersive Virtual Environments
This paper proposes the systematic study of the design, evaluation, and application of VE interaction techniques, based on a formal task analysis and categorization of techniques, using multiple performance measures.

- 1 April 1995
Treatment with virtual reality graded exposure was successful in reducing fear of heights, and the treatment group was significantly improved after 8 weeks, but the comparison group was unchanged.
