Low-cost, room-size, and highly immersive virtual reality system for virtual and mixed reality applications

Providing realistic stimuli has traditionally posed a challenge for virtual reality researchers. Most efforts have been done with visual information. Different technical solutions, such as head mounted displays and cave systems, have been presented through the years improving the state-of-the-art instrumentation. In recent years, an increasing interest in virtual reality for rehabilitation has given rise to low-cost devices with impressive performance. We created a room-size immersive setting with low-cost technology that can be used to simulate large virtual worlds and explored by walking in the physical world.
