Overview

• Researchers have created odor generators that can be worn on the body to recreate smells in virtual reality.
• The wearables use heated, scented wax to generate localized smells that correspond with the virtual environment.
• The researchers were able to produce 30 different scents to stimulate the user's sense of smell in VR.
• The technology could enhance immersion in VR for gaming, entertainment, education, and therapeutic applications.
• Though promising, the interfaces need further testing and improvement to address safety, efficacy and realism.
