What it does
Harmony Beat is a three-user interactive fitness device designed for self-care rural elders, aiming to relieve hand muscle atrophy through rhythmic training and reduce social isolation.
Your inspiration
Inspired by the structure and collaborative nature of drum kits, the design transforms rhythmic drumming into elderly rehabilitation.
How it works
Harmony Beat operates as an interactive rhythmic exercise device designed for three elderly users. Each participant is positioned around a circular drum-like structure, where modular drum pads are arranged. These pads respond to touch with synchronized LED light rings and sound effects, guiding users to follow rhythmic patterns. The system provides preset rhythm tasks with adjustable difficulty, encouraging users to strike specific pads in time. The visual cues not only help maintain engagement but also stimulate hand-eye coordination and upper limb movement. As users collaborate to complete rhythm sequences, the system offers real-time feedback and celebratory responses, enhancing motivation and enjoyment. The design transforms passive muscle training into a socially engaging, game-like experience that supports both physical and emotional well-being.
Design process
During the initial research phase, I focused on the physical condition and daily routines of self-care elderly individuals in rural areas and identified hand muscle atrophy as a major concern affecting their quality of life. Based on interviews and case studies, I defined three core design goals: simple motion guidance, social interaction, and motivational engagement. Inspired by the form and structure of modern drum kits, I proposed a circular three-user interaction system and refined the layout through sketching and concept modeling. In the mid-stage, I used foam prototypes to test the scale and tactile feedback of the drum pads. Later, I integrated LED light rings and rhythmic sound feedback to enhance visual cues and interactive clarity. The final product—Harmony Beat—combines rhythmic training, social cooperation, and muscle rehabilitation, addressing both the physical and emotional needs of elderly users in rural communities.
How it is different
Harmony Beat stands out from conventional elderly fitness devices by combining upper-limb muscle training, multi-user collaboration, and sensory feedback in one cohesive design. While most rehabilitation products focus solely on functional exercise—often repetitive and solitary—Harmony Beat transforms physical training into a playful group experience inspired by percussion instruments. Through guided rhythm tasks, LED light cues, and responsive sound effects, it engages users in an enjoyable and motivating way. Unlike typical one-on-one devices, it encourages three seniors to interact face-to-face, fostering emotional connection and mutual support. This “cooperative rehabilitation” model brings both social warmth and physical benefits—something especially valuable in rural contexts where emotional companionship and healthcare resources are limited.
Future plans
Future development will focus on data tracking and adaptable modes to expand use in rural communities and enhance rehabilitation outcomes.
