Digital interface is the main platform of Human-Computer Interaction(HCI).Scientific and reasonable interface design can promote efficient and harmonious HCI.The evaluation of the effectiveness of digital interface HCI can effectively save time resources and development costs,and lay a solid foundation for the design of the interface.Using eye tracking technology to evaluate the effectiveness can objectively reflect the users visual psychology and cognitive thinking process.Based on the evaluation mechanism of this technology in human-computer interface interaction,this paper summarizes the current research status,and points out that its future application and development trend will focus on algorithm optimization,model calculation,multiple fusion and insensible interaction.
