Using an olfactory display, a device to present odors controlled by a computer, enables a virtual reality experience with added olfactory information called ''olfactory VR''. Our research aims to apply olfactory VR to cognitive enhancement, and we have developed an olfactory VR game to improve cognitive function. This is currently being tested by elderly people and focuses on sensory memory of odors. Players are required to memorize odors without linguistic information and select the odor memorized from a choice of three odors encountered in the game. Odors in our virtual world are also represented visually in the game landscape thorough the head-mounted display with the odors generated by the connected olfactory display as the player interacts with the game.Attribution 4.0 International LicenseCCS Concepts: Human-centered computing → Interaction design; Applied computing → Life and medical sciencesHuman centered computing → Interaction designApplied computing → Life and medical sciences10.2312/egve.202414042 pages
