Relaxation Training with Biofeedback in Virtual Reality: Discussion of Wearability

Abstract

This paper describes a mobile learning app aimed to be used for relaxation training, primarily for adolescents suffering from tension-type headaches. Combining expertise from neuromedicine, psychology, and technology-enhanced learning, we have developed a concept and a working prototype for low-cost biofeedback training applications. The system uses virtual reality technology for delivering visual experience on both low-cost and advanced virtual reality glasses. A wirelessly connected wristband is used to measure user’s pulse and adjust the training scenario and the virtual environment based on the heart rate data. The app simulates an immersive environment of a tropical beach with several interactive visual and audio elements. The main goal of the simulation is to make the weather as calm as possible by reducing own heart rate. The progression through the scenario is guided by a therapist’s voice with some degree of self-exploration. Repeating the exercise would make the user able to go through the scenario without using the app, learn how to relax, and ultimately combat tension-type headache. The prototype is currently being evaluated in a feasibility study with a small group of participants that answer a questionnaire and interview questions after trying the app. The first evaluation results are presented in the paper. The results are discussed with a focus on wearability – suitable for wearing – of virtual reality glasses and of the wristband.
