Based on the premise of the global aging background and the deficiency of the aging smart products in optimizing and designing experience for the elderly group, this study proposes a user experience design and product design paradigm based on VIGT, which is committed to establishing a good experience interaction and hands-on experience with the elderly group. To provide an efficient, customizable and highly identifiable complementary intervention for the elderly population and extend the use time. In the validation and experiment part, the effects of improved user experience design and product design based on VIGT model were evaluated through subjective interview questionnaires and communication experiments. The results show that the user experience design and product design based on VIGT lead to increased patient satisfaction, effective use efficiency, and stronger emotional connection. In addition, user experience design and product design interventions based on visual effects led to greater patient concentration and reduced negative emotions.
