Garden-GaTE (Garden-Game Therapy Experience) is a proof-of-concept multisensory rehabilitative VR game. It offers a gardening scene, including its olfactory and audio-visual stimulations, enabling older people to immerse themselves and navigate within a virtual environment (VE). This game examines the multisensory approaches used in cognitive impairment, VR-based interactions, and VR elements that aid with therapeutic values.
