Smell Revived is a virtual-reality-based training system that helps people regain their sense of smell after recovering from COVID-19. This project aims to help patients with smell dysfunction, such as parosmia and anosmia, recover through smell training. By using virtual reality, it provides multisensorial stimulation, which helps patients retrain their brain and nose to recognize smells. Bringing virtual reality to smell therapy makes the therapy experience more fun, engaging, and effective. Users visit virtual environments to interact with realistic objects while the wearable device releases the corresponding scents.
