    Demo of the Extended Wearable Olfactory Display for Multisensory VR Experience
    (The Eurographics Association, 2024) Zou, Zhe; Prasetyawan, Dani; Wu, Hsueh-Han; Cheng, Kelvin; Lee, Sungho; Nakamoto, Takamichi; Tanabe, Takeshi; Yem, Vibol
    We present a prototype of an eight-channel wearable olfactory display, capable of delivering a diverse range of olfactory stimuli using eight liquid odorants - a configuration that, to the best of our knowledge, is unprecedented. The system is designed to be compatible with various head-mounted displays (HMDs), allowing the integration of olfactory stimuli with visual and auditory inputs for a more immersive user experience. To assess the system's performance, we developed a corresponding virtual reality (VR) application. This system holds significant potential for advancing human-computer interaction by enhancing sensory experiences and offering a more immersive, multisensory interface.

    Demonstration of an Olfactory VR Game to Improve Cognitive Function
    (The Eurographics Association, 2024) Sunami, Ryota; Nakamoto, Takamichi; Cohen, Nathan; Kobayashi, Takefumi; Yamamoto, Kohsuke; Tanabe, Takeshi; Yem, Vibol
    Olfaction has a deep connection with cognitive function and it is expected to be applied in cognitive rehabilitation. 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.

    Extension of Wearable Olfactory Display for Multisensory VR Experience
    (The Eurographics Association, 2024) Zou, Zhe; Prasetyawan, Dani; Wu, Hsueh Han; Cheng, Kelvin; Nakamoto, Takamichi; Hasegawa, Shoichi; Sakata, Nobuchika; Sundstedt, Veronica
    An olfactory display is a device that allows users to experience a range of olfactory stimuli. Despite its potential to enhance user experience, challenges remain, including limited odor variety, unwanted odor persistence, constraints on continuous operation, and a restricted range of scent generation. We propose a novel wearable olfactory display that incorporates up to eight odor components to expand the variety of generated scents. Additionally, the device integrates an airflow control system, deodorant filtering, and optimized electrical and mechanical structures. This design aims to provide a more immersive user experience in virtual reality (VR) environments by significantly improving the generation of olfactory stimuli.

    Investigating the Effects of Olfactory VR Content on Cognitive Function in Elderly People
    (The Eurographics Association, 2024) Sunami, Ryota; Nakamoto, Takamichi; Cohen, Nathan; Kobayashi, Takefumi; Yamamoto, Kohsuke; Tanabe, Takeshi; Yem, Vibol
    Smell is a fundamental human sense, and its use is expected to enhance cognitive functions. In addition, virtual reality technology allows humans to experience virtual worlds and is expected to be applied to rehabilitation in spaces where movement might be limited, such as elderly care facilities and hospitals. We are conducting research on the use of olfactory VR game content to enhance cognitive function in elderly people and undertaking a study of the effects. Early indications suggest that while there may be some ceiling effects, improved scores for attention and mind rotation tasks are detected, indicating that olfactory VR content has the potential to enhance cognitive function in elderly people. Based on these results we can determine the appropriate contents of the cognitive test to evaluate the olfactory game.
