Abstract:As an extension to the existing VIREP project, a new virtual relaxation environment has been designed for the use in CBP treatment that makes use of VR. This environment makes use of the Zephyr BioHarness 3 to gather data from the user to display biofeedback (of the heart rate and respiratory rate) in the environment in an immersive way. Two initial prototypes were created and then tested for their intuitivity and provided level of relaxation with ten participants. The results showed that heart rate was easy to interpret, but the respiratory rate was not responsive enough to be completely intuitive. Feedback from the evaluation of the prototypes was taken into consideration, and a final prototype was created. However, due to not having implemented a script that captures the data from the sensor in real-time to be fed to the application, manual input is at this point needed for the final prototype to properly and automatically show biofeedback. The final prototype could be improved by implementing such a script and testing the result with end users to properly judge the efficiency of the designed environment.
