footprint tracking mat 3d model

"A modern, bright, and spacious living room in a smart home, designed for elder care rehabilitation. In the center, a muted blue步态训练毯 (gait training mat) with clearly marked, high-contrast yellow footprints and guiding lines is laid out. Facing the mat is a large, wall-mounted smart TV displaying an interactive UI. The UI is in a dark mode with a vibrant, glowing green silhouette of a person (the 'virtual shadow') walking gracefully across it. An elderly person (around 70-80 years old, wearing comfortable home clothes and the smart waist belt) is actively following the virtual shadow's movements on the mat. Their posture is being subtly corrected as they step on the illuminated footprints. On the TV screen, the UI also features elements of a balancing game: perhaps a subtle "wobbling" effect on a virtual character or small "gold coins" for the elderly person to virtually "collect" by maintaining balance. The overall atmosphere is positive, encouraging, and technologically advanced, yet warm and inviting.
