Forestlight: A Virtual Reality Respiratory Biofeedback System Using Interactive Lighting for Pressure Relief

Abstract

Light is a common environmental medium that is used to evoke mood and provide an immersive experience. In this paper, we present the design and implementation of Forestlight, a virtual reality (VR) biofeedback System that helps users take deep breath for pressure relief through interactive lighting. We envisioned the breath-based interactive lighting in a virtual forest environment might be effective in stress reduction. With Forestlight, we also wanted to explore the opportunities for the application of virtual reality technology in respiratory biofeedback system. Based on the current stage of the prototype design, we conducted a user study to examine the effectiveness of stress reduction. This study suggests that the biofeedback-driven interactive lighting in VR system can perform as persuasive technology in the domain of health self-management. The interactive lighting that combines decorative and informative aspects in VR system can be pleasant and helpful to the user.
