In modern life, emotions are often like a tangled mess, difficult to unravel. "Finger Clue," whose name signifies the act of "combing through emotions," is a stress-relief product dedicated to the tactile experience. Upholding the principles of ESG circular design, we breathe new life into discarded elements and recycled materials such as wood chips through 3D printing and mechanical design. Designed specifically for heavy tech (3C) users experiencing chronic tension, seniors in need of sensory stimulation, and individuals seeking stress relief, "Finger Clue" provides unique tactile feedback. As the user's fingertips glide across the relief surface and interact with the internal mechanisms, it not only eases stiffness in the hands but also, through a pure sensory experience, gradually untangles and settles inner anxiety, transforming intangible stress into tangible tranquility.
