Online Collaborative Interaction Design For Middle-aged And Elderly Internet Celebrities In Short Videos

Short video carriers have the advantages of low reading threshold and high-density information.According to the data insights released by QuestMobile in May 2020,middle-aged and elderly people have become the largest incremental mobile netizens.Compared with 2019,the use of short videos by middle-aged and elderly people has increased by 25%.Short videos are rapidly infiltrating into the middle-aged and elderly groups.More and more middle-aged and elderly people are learning about national events,chasing hot spots,and even learning knowledge on Douyin.Short video scenes are quickly activated among the middle-aged and elderly groups.Especially under the influence of the epidemic in recent years,middle-aged and elderly people have more leisure time due to home isolation,and they have a deeper sense of dependence on digitalization,further developing the content consumption habit of short videos.Short video applications in the current market provide new tools for middle-aged and elderly people to acquire knowledge,socialize entertainment,and show themselves,strengthen the link between the middle-aged and the elderly and society,and enhance the social use and social participation of middle-aged and elderly people after they withdraw from the labor market..Although the application of short videos among middleaged and elderly groups has grown significantly,there are still many middle-aged and elderly people who have difficulties in the use of digital products and network security awareness.Although the current short video has been upgraded to be"appropriate for aging",there are few short video applications independently developed and designed for the middle-aged and elderly groups.Therefore,the current short-video industry still has the following blank markets.2.There is no interface and functional design that is cognitively friendly to middle-aged and elderly people;3.There is no caring design based on the selfworth of middle-aged and elderly people;4.There is no support for middle-aged and elderly people.Short video content for the elderly-only knowledge community.Therefore,the purpose of this study is to take the middle-aged and elderly groups as the starting point for the design of short video applications,and to improve the mobile short video application experience of middle-aged and elderly users in terms of interface,function,and form.This research is divided into four stages:(1)Desktop research stage:The relevant characteristics of middle-aged and elderly people,the advantages and disadvantages of short video platforms,and t he online collaboration mechanism are fully studied in literature,which has laid a solid theoretical foundation for subsequent research.;(2)Market research:understand the problems existing in the use of short video platforms by middleaged and elderly people in the current market through relevant data,and fully tap the blank market in the mobile short video field for middle-aged and elderly groups;(3)User research stage:This stage is mainly through Questionnaire research,interviews and observation methods are used to deeply explore the needs of middle-aged and elderly users for smartphone functional operation and mobile short video content;(4)Design experiment stage:According to the needs learned from previous literature review,market research,and user research Function transformation is carried out at points,and the core functions are retained through the Kano model,and the design strategy and design scheme are carried out based on this,and finally the effect evaluation is carried out through the satisfaction measurement,which provides data support for the iterative optimization of the design.This paper fully discusses the needs,cognition,and behavior of the middle-aged and elderly groups,and plays a certain inspirational role in the design of the APP for the care of the middle-aged and elderly groups.This design is actually a multifunctional aggregation platform tool.Design,content construction and user services are carried out in "aging-friendly" design innovation,and its value is reflected in the use of this APP by middle-aged and elderly people to achieve the purpose of "useful","easy to use" and "useful".The final output results have been tested by the satisfaction test.The evaluation results are good,the satisfaction is high,and the implementability is strong.It is an innovative short video application design,which has practical guiding value for similar designs.
