Research On Users' Cognitive Behavior And Physiological Characteristics In Visual Information Interface

As a new type of human-computer interaction interface,visual information interface plays a very important role in the process of information transmission.In order to improve the efficiency of information transmission and ensure the completion of the task,research on human in this process is very essential.Therefore,bring a simple interface to the actual task,From the perspective of user cognitive behavior,and take records of the user's physiological characteristics in the task as the secondary verification.Due to the features of light and low cost,small general purpose aircraft is playing an important role in a variety of fields and promoting the development of the diversity of the industry.However,the pilot's power qualification and aircraft itself lead to more accidents.This project is aimed at improving the professionalism and safety of small.aircraft,takes Cessna C172 as the study sample.It summarizes the key missions in the flight manual:climbing,descending and turning.Then it also makes a deep classification by cognitive complexity based on SRK model and task patterns based on Petri net.Eventually,a more detailed classification of the mission is obtained.After these,a series of experiments are done to evaluat the operational performance of pilots in different environment.It find out that when a person completes a certain task consecutively for a certain period of time,his cognitive efficiency is not immutable because of the consumption of cognitive resource which is related to cognitive complexity and task patterns.These results can be references for the design of flight Mission and flight interface.
