This paper aims to effectively enhance traffic command hand signal recognition in bad weather, accurately convey command information and reduce the rate of traffic accidents.Firstly, it analyzes the current situation and shortcomings of traffic command products. By constructing a traffic police and driver traffic context relationship model, it gives insight into key design issues and optimization of traffic command glove function design. Secondly, explore the way of interaction between intelligent fabric and human body. Design dynamic digital symbols based on luminous fabric to enhance the gesture visibility of traffic gloves, improve the glove interaction effect, and strengthen the efficiency of information interaction between traffic police-driver. Finally, we design the corresponding scheme according to the above analysis. The traffic glove based on controllable luminous fabric can effectively enhance the gesture visibility. In this way, the efficiency of traffic police is improved. The construction of interaction relationship model helps to quickly find the problems of product usage and obtain the corresponding design objectives. The proposed product design based on light-emitting fabric provides new ideas for future traffic command product design. It also provides a helpful idea for related research and design practice.
