Rewind is an interactive app designed to support elderly individuals with dementia through meaningful recollection and social engagement. By combining familiar gestures with multi-sensory stimulation, Rewind helps evoke personal memories in a natural and enjoyable way. Using motion-tracking technology, the app guides users to perform intuitive actions, which are mirrored as immersive audio-visual feedback on a paired device. These sensory interactions not only spark cherished memories but also foster deeper connections with caregivers and loved ones, making every moment more meaningful.
