This study is an investigative study, taking the elderly in Beijing community as an example, and taking photos of different areas in the home environment of the elderly who agree to participate in the study (a total of seven aspects, including pathways/entrance to home, hallways, stairs/steps, living room, kitchen, restroom, bedroom). Subsequently, the multi-modal large model GPT-4o and a professional occupational therapist will use the "Home Environment Assessment" scale to evaluate the home environment shown in the photos and give corresponding suggestions for modification. A professional occupational therapist (non-evaluator) will analyze and compare the evaluation results and guidance recommendations of GPT-4o and the evaluator, and compare whether there are any significant differences between the two analysis results.
