Brown University researchers found that subjects who had access to optic flow adapted faster and made it to virtual targets more easily than those without. The study suggests that optic flow plays a crucial role in navigating through environments.
Researchers used virtual reality to manipulate bodily self-consciousness, demonstrating that spatial unity and bodily self-awareness depend on brain mechanisms. The study indicates that humans' sense of the embodied self relies on brain activity at the temporo-parietal junction.
Researchers used VR goggles to induce out-of-body-like experiences in healthy people, suggesting a disconnect between brain circuits that process sensory information may be responsible. The findings help solve the question of how we perceive our own bodies and may have implications for training people to perform delicate tasks remotely.
C6 is a 10-foot by 10-foot virtual reality cube that immerses users in computer-generated 3-D images and eight channels of audio. The upgraded room now projects more than twice the resolution produced by any other VR room, with 100 million pixels.
A modified home video game system has been developed to aid stroke patients in performing hand exercises, utilizing virtual reality and traditional therapy techniques. The system, costing less than $600, promotes engaging patients and provides immediate feedback on performance.
Researchers found that goalkeepers are unable to accurately predict the trajectory of a spinning football, relying on the ball's current heading direction. The study suggests that inherent limitations in the human visual system hinder this ability.
A Case School of Engineering professor is using virtual reality to train brain and heart surgeons, reducing learning time and allowing independent practice. He aims to expand minimally invasive techniques to complex surgeries, virtually eliminating the need for heart/lung machines.
Researchers developed a virtual reality system using 3D echocardiography to analyze heart defects. Ten heart specialists successfully diagnosed healthy and unhealthy hearts within minutes, showcasing the technology's potential for better understanding cardiac anatomy.
The Marine Corps has created a dedicated virtual-reality training system for its assault amphibian vehicles, allowing for increased training capabilities due to range and ammunition supply constraints. The Virtual Environment Assault Amphibian Vehicle (VEAAV) training system was developed by a Navy-Marine Corps team in just six months.
Researchers are investigating virtual reality therapy as a potential treatment for acute post traumatic stress disorder (PTSD) in active-duty military members. The therapy aims to provide innovative tools and techniques for early intervention and treatment of PTSD symptoms, including those related to combat.
A virtual reality game has been found to significantly reduce pain responses in children with severe burns, with all but one child showing a decrease of at least 2 points on the Faces Scale. The game was more effective than analgesics alone in reducing pain and anxiety.
Researchers found that virtual reality significantly reduces pain-related brain activity, with drops of up to 97%. The study used specialized magnetic resonance imaging to track brain activity and showed a significant change in conscious perception of pain when virtual reality was used.
The Virtual Haptic Back system uses a sophisticated haptic interface to simulate the sensation of touching a human back. Medical students can practice palpation skills on simulated backs, improving their ability to diagnose dysfunctions and address two major challenges in osteopathic doctor training.
Researchers found that simulated games in virtual reality boosted children's belief in their abilities, regardless of their physical limitations. The therapy also gave them a chance to succeed in types of play they might have difficulty accessing otherwise.
The Keck Center for Active Visualization in Earth Sciences will enable geologists to build and test large-scale models of the Earth's interior. The facility will allow researchers to interact with their data in a more realistic way, using virtual reality tools developed by UC Davis researchers.
