Virtual reality exposure therapy (VRET) is one of the few interventions supported by randomized controlled trials for the treatment of combat-related posttraumatic stress disorder (PTSD) in active duty service members. A comparative effectiveness study was conducted to determine if virtual reality technology itself improved outcomes, or if similar results could be achieved with a control exposu...

Simulation and visualization of rover behavior are critical capabilities for scientists and rover operators to construct, test, and validate plans for commanding a remote rover. The VIPER system links these capabilities, using a high-fidelity virtual-reality (VR) environment, a kinematically accurate simulator, and a flexible plan executive to allow users to simulate and visualize possible exec...

Recent research suggests Virtual Reality Exposure Therapy (VRET) for the treatment of fear of flying as an important reliable technique for this phobia. This paper focuses on the role of the therapist during an exposure session. Six therapists were observed in 14 sessions with 11 different patients. Results show that in 93% of the observed sessions, therapists started with a similar flight patt...

More than two thirds of the individuals who have strokes are over the age of 65. Therefore, as the global population continues to age, the risk of stroke is expected to increase substantially. Virtual reality (VR) is an emerging therapy that holds promise for the rehabilitation of patients with chronic stroke conditions. VR is an interactive, computer-based simulation of real life tasks, occurr...

Signal transduction therapy for cancer targets specific molecular elements that are essential for survival of the tumor. Gleevec has a profound effect on early phase chronic myeloid leukemia because it inhibits the major driving factor of the tumor, BCR-ABL. Almost all other cancers depend on several factors, and blocking a single signal transduction factor is largely ineffective. Effective sig...
