Product Appearance Design of In Vitro Diagnostic Card Using Colloidal Gold Method Based on Kansei Engineering

In vitro diagnostic (IVD) tests using immune colloidal gold technique are widely used in home disease prevention and disease diagnosis and have great potential for development. However, as a medical product, the existing design of the test card tends to focus on the satisfaction of the product's function rather than the user's emotions, so it is necessary to design the appearance of products from an emotional perspective and bring care to users. This study takes IVD cards using colloidal gold method as the design object, combines with Kansei Engineering (KE) as the theoretical guidance, quantifies the product characteristics by using Quantification Theory Type 1 (QT1), and constructs the correlation model with high confidence between Kansei words and design elements through multiple linear regression analysis. Finally, the test card design strategy is proposed according to the data, which can help relevant enterprises determine the direction of product form development.
