Abstract

The home-use phototherapy beauty device has a high market penetration rate, but its single interaction mode and lack of personalization limit the further enhancement of user experience. To address these issues, this research, based on multimodal interaction design theory, proposes an innovative design solution for phototherapy beauty devices as smart wearable products. Firstly, user requirement elements were analyzed and ranked for their weight using Python web scraping technology, the KJ method (Affinity Diagram), and the AHP (Analytic Hierarchy Process), thereby determining the key design requirements for the phototherapy beauty device. Secondly, the multimodal interaction information architecture of the device was reconstructed, and the key user needs were translated into corresponding functional design directions for design reasoning, resulting in a new product functional framework. On this basis, specific design proposals, such as integrating a directional audio player, optimizing the interaction interface, adding a detachable eye protection lens, and adopting a rotating folding structure, were suggested. These aim to enhance the product's fun, usability, and safety, thereby optimizing the user experience and providing theoretical and practical guidance for the innovative design of phototherapy beauty devices and similar smart wearable products.
