When you see the Computer Assisted Rehabilitation Environment system (CAREN) in action, the room-sized simulator resembles a giant video game, complete with avatars. Scenes projected on its 180-degree screen range from walking through a forest to driving past cityscapes to riding on a wave-tossed boat.
The three-dimensional virtual reality system engages and entertains – but its purpose is serious.
The system’s immersive environment and interactive gaming elements safely challenge people to learn new strategies for coping with changes in their balance, coordination or mobility caused by disability, traumatic injury or aging. The advanced technology also gives researchers the scientific tools they need to advance the diagnosis and treatment of musculoskeletal and neurological disorders.
