Research And Practice Of Visual Attention Oriented Micro Lecture Video Design

In the era of "Internet +",the mode of information dissemination is constantly updated,and the limits of space and time are gradually broken.The sudden COVID-19 viruses has led all universities have to suspend their returning to school,micro-class video provides a helping force for the solution of the teaching problem in colleges and universities teaching during the epidemic by virtue of its short time,novel performance,outstanding core,convenient and fast and other advantages.Because of not being constrained by space and time,the number of users and videos of micro-class video is increasing,the designed quality of micro-class video directly affects the effect and efficiency of users’ access to video information,how to improve the quality of the design has become an important issue.This paper begins with attention,explores the users’ demand elements of micro-class video design,extracts and analyzes the effect of each element on the user’s visual attention,it also builds micro-class video design principles,implements detailed design schemes and practice case design,so as to explore the micro-class video design at different cutting angles through the viability of eye movement experiments verify case theory.Firstly,this paper studies and combs the status at home and abroad of micro-class video theory,clears the concept of micro-class video,it classifies the type of video in the micro-class according to the design of micro-class video,and takes the comprehensive editing class as the research object.It also makes an overview and analysis on users’ viewing needs and visual experience needs,produces and uses questionnaires for demand research,and extracts the elements of color、graphics、text、composition and character design in micro-class video design;Besides,it introduces attention concepts into micro-class video design and analyzes the visual effect of each design feature attribute on the attention four dimensions,and then summarizes the three design principles of micro-class video,that is simplicity、prominence、guidance、clears variable factors and scope of each design element under three principles,it determines the design objectives according to the principle of video design in micro-class,and makes a design plan;What’s more,it conducts design practices according to the "Cultural Creative Products" micro-class video,refines and implements the use of design elements under the visual influence of attention dimension,by following three design principles,so as to enhance the user’s ability to focus on the four dimensions and enhance the visual experience;Finally,this paper makes design validation by using eye movement experiment gaze time,gaze points,gaze hot spots,gaze sequence indicators,so as to explore the applicability of attention theory to the guidance of video design in micro-classes.This paper takes micro-class video as a product,explores users’ needs in depth,extracts and analyzes them as design elements,guiding by attention theory,it builds a micro-class video design inquiry for visual attention,summarizes the design principles,the design process,and carry out case practice design and experimental verification,so as to provide a new pointcut and thinking mode for the design of this type of product,promote the design development of micro-class video and improve the design quality.
