Behavior Analysis of User Interaction on Online Short Video Platform

BackgroundWith the rapid development of smart phones, the platform for people to obtain information and resources has shifted from traditional media carriers to smart phones and smart devices. Short video applications are favored by all users and capital, and the number of users, industry scale and social influence are increasing. Under the background of covid-19, the application of short format video has received unprecedented attention and influence. At present, short videos have gone beyond “watching” and added links with user experience, user psychology, consumer behavior and other factors. This paper attempts to analyze the development status of China's short video industry from the perspective of user experience and user psychology, and study the types of short video under different operating conditions, the differences of user experience and user psychology, and the changes of interactive thinking., Especially in the aspect of emotional behavior, it puts forward effective design strategies for the application industry.Research Objects and MethodsThis study compares and analyzes the visual interface, gesture operation and interaction mode of typical short video applications (taking Tiktok, Kwai and wechat account as examples) from three aspects: interface visual perception, interactive behavior perception and psychological experience. Through the comparative study of three short video application products, this paper analyzes the similarities and differences, advantages and disadvantages of Tiktok, fast and wechat channel functions, and summarizes the user experience and interaction design strategies of these short video applications. The questionnaire data collected 234 short video users through the online questionnaire in January 2022. The content is the questionnaire survey of “current situation of short video application”, which mainly analyzes the zero order correlation and covariance analysis between psychological duration. Personal users accept short format video and user experience problems. The use of emotional micro behavior in various countries and regions was investigated by questionnaire. The gross John Emotion Regulation Questionnaire (ERQ), a measurement tool of this study, has 10 items, which are divided into two factors: cognitive reappraisal and expression inhibition. Each item is scored with 7 points (1 = very non-conforming; 2 = relatively non-conforming; 3 = slightly non-conforming; 4 = uncertain; 5 = slightly conforming; 6 = relatively conforming; 7 = very conforming). The higher the score, the higher the tendency.ResultsThrough the comparative study of three short video application products and user questionnaire survey results, it is concluded that there are differences in user experience attention, short video duration and psychological demand motivation among different ages. Compared with ordinary users, older users have a shorter time span to buy videos. They found that they spend more time on live video formats than ordinary users.ConclusionShort video application should fully integrate user experience, user psychology and interaction mode, with the goal of improving interaction experience, interface diversification and personalized design. Meet the needs of different groups of users, optimize the user experience, tap the potential needs of users, increase user stickiness, and enhance the value and competitiveness of short video applications.AcknowledgementsFunded by College of Chinese & ASEAN Arts, Chengdu University, the major scientific research achievements.

To reveal the associative mechanism between college students' short-video use and learning burnout in the digital era, this study, based on the Social Comparison Theory, the Two-dimensional Model of Envy, and the Three-dimensional Model of Learning Burnout, employed thematic analysis to conduct semi-structured interviews with 6 full-time college students. The focus was on the interactive relationship among short-video usage behaviors, the triggering process of social comparison, and the experience of learning burnout. The findings show: (1) College students' short-video use is characterized by "duration differentiation (high duration: 5-8 hours/day vs. medium-low duration: 2-4 hours/day), concentrated timing (mainly before sleep), fragmented contexts, and inefficient management". (2) Short videos primarily trigger upward social comparison in dimensions of academic achievement, material conditions, and physical appearance. Emotional responses are dominated by benign envy, and the intensity and persistence of online comparison are significantly weaker than offline comparison. (3) Short videos have a "double-edged sword" effect on learning burnout-planned intermittent use in the short term can supplement psychological resources to alleviate burnout, while unmanaged excessive use in the long term consumes attentional resources to exacerbate burnout. This study provides qualitative evidence for understanding the relationship between college students' digital media use and learning psychology, and offers practical references for universities to carry out media literacy education and learning burnout intervention.

Short videos have become increasingly popular in recent years, leading to the rise of many short video platforms with large user bases, such as leading platforms like TikTok. The user groups on these platforms are vast. With the rise of short-video platforms, TikTok, as one of the leading players, has become a highly influential social media platform worldwide. With the development of short videos, personalized recommendations are also playing an increasingly important role in short videos and are constantly evolving. This report examines the definition, classification, and evolution of personalized recommendation systems, along with their applications and the development trends and suggested countermeasures in short video platforms, with the objective of analyzing the current status and emerging trends of personalized recommendations in this domain. Research has found that personalized recommendations are of great help to the development of short videos. Enterprises need to keep up with the times and constantly update their personalized recommendation systems to enhance user experience and retain more users. Meanwhile, users also need to improve their ability to distinguish during the process of using short videos. In addition, the government should supervise enterprises to ensure the healthy application and development of personalized recommendations in short videos. It provides valuable reference information for content creators, short video platforms, and end users.

Vascular cognitive impairment (VCI) severely affects patients’ quality of life and imposes a substantial burden on families and society. Health education on VCI is an effective approach for preventing and slowing disease progression. Currently, short videos and WeChat official account articles demonstrate significant potential in disseminating health information. However, no evaluation of the quality and content of VCI-related information on these platforms currently exists. Therefore, we conducted a cross-sectional assessment of VCI-related information quality on the Chinese platforms TikTok, Bilibili, and WeChat official accounts. A total of 72 Chinese short videos from short video platforms (TikTok and Bilibili) and 61 articles from WeChat official accounts were screened for inclusion. The quality and reliability of the videos and articles were evaluated using the Global Quality Scale (GQS), Journal of the American Medical Association (JAMA) benchmark criteria, and Discern Instrument for Systematically Critical Evaluation of Reliable Nealth Information. Content completeness was assessed on the basis of established VCI guidelines. Comparative analyses were conducted on information from various platforms and publishers. The scores of WeChat official account articles were significantly greater than those of short videos across all the metrics: Discern Instrument for Systematically Critical Evaluation of Reliable Nealth Information score (48.57 ± 7.33 vs 39.10 ± 6.35, P < .001), GQS score (median 4.00 [IQR 3.00–4.00] vs 3.00 [2.00–3.00], P < .001), JAMA score (median 1.00 [1.00–2.00] vs 1.00 [1.00–1.00], P < .001), and total content score (6.52 ± 1.79 vs 4.38 ± 1.91, P < .001). Short videos on TikTok had higher total content scores than those on Bilibili did (4.94 ± 1.98 vs 3.69 ± 1.59, t = 2.90; P = .004). Videos and articles published by doctors, medical institutions, and healthcare vertical media achieved significantly higher total content and JAMA and GQS scores than those published by general individuals did. The overall quality of VCI-related short videos and articles was moderate. Compared with short videos, WeChat official account articles demonstrated higher quality and superior content completeness. Short videos on TikTok outperformed those on Bilibili in content scoring. Information from doctors, medical institutions, and healthcare vertical media publishers was of higher quality than that from ordinary individual publishers.

The theme of this paper is to study the impact of short video platforms on users’ behaviors, and film interpretation is chosen as an example. As a new medium of information dissemination, short video platforms have developed at a very fast speed in recent years. While it has brought a lot of benefits to the public, it has also brought bad far-reaching effects on the people. The main feature of short video platforms is their short video production time and simple process; Second, the speed and scope of information dissemination of short video platforms is extremely fast, small to different cities, and large to different countries. Among them, the TikTok platform is the most typical example. TikTok short videos are not only spread in China but also respected by other countries abroad. The short video propagated in the short video platform can transmit a large amount of information at home and abroad in only ten seconds of video. This research helps short video platforms to improve and increase consumer satisfaction. It can also play a role in promoting things and raising awareness among the users.

Purpose The advent of social commerce has precipitated a paradigm shift in consumers' acquisition of product information. This shift has particularly impacted short-video platforms, which have become one of the most convenient and important sources for consumers to encounter promotional videos. Information encounter (IE) is an important trigger for short video users' unanticipated consumption behavior. This study aims to explore the formation mechanism and influence factors of consumer information encountering behavior (CIEB) in short video platforms. Design/methodology/approach Twenty-three short video users were selected as participants using semi-structured interviews, and the interview data were analyzed by three-level coding with the help of grounded theory, identifying a total of 55 concepts, 22 subcategories and 8 main categories. Findings Combined with the Attention-Interest-Desire-Action (AIDA) model and the IE episodes provided by Erdelez, this study finally constructs a process model of users' CIEB in short video platforms, including four stages: information attention, interest attraction, desire activation and action implementation. In addition, the influencing factors of users' CIEB in short video platforms can be categorized into four aspects: first is the individual factors including consumption level, consumer decision-making patterns, information literacy and user real-time status; second is the information-related factors including information credibility and information quality, among which information credibility is particularly critical in CIEB in short video platforms, and information credibility includes uploader, store and brand credibility; third is the platform-related factors mainly include algorithmic recommendations and quality of platform services, and finally the environmental factors include previous activities. Originality/value The findings of the study not only deepen users' recognition of their consumption process but also provide a theoretical basis and practical implications for short video commerce to further optimize and enhance the consumption experience.

In recent years, the short video has gradually become a way for people to obtain information, entertain themselves, and spread their opinions. The number of users of short video platforms such as Tik Tok and Kuaishou shows an increasing trend. With the proposal of a rural revitalization strategy, the spread of agricultural science popularization knowledge also occupies a place in short video platforms such as Tik Tok, which plays an extremely important role in solving the agricultural knowledge problems for the public. Based on the three-dimensional classification of short videos of agricultural science popularization, this paper analyzes the narrative strategies of short videos of agricultural science popularization on the short video platform Tik Tok from three angles: narrative theme, narrative structure, and narrative discourse. This study also summarizes the creation rules of this kind of short video in combination with the team’s own experience of creation, so as to promote the wide spread of agricultural science popularization knowledge and make more knowledge about agriculture, the countryside, and farmers enter the lives of ordinary people

The purpose of the article discusses the consumption behaviour, influencing factors and personal factors of short video users through literature review, expert interviews and research results. Among the consumption behaviour, it studies herd mentality, blind mentality, impulsive mentality and experiential consumption. Among the influencing factors, it studies advertisements, live commerce, community effects and consumption reasons. At the same time, it also studies the influence of personal factors on short video users' consumption behaviour. Whether short video users consume in short video platform and how much does a person cost has a significant positive correlation with advertisements, live commerce, the community effects and consumption reasons; Incomes in personal factors have a positive significant influence on monthly cost; The consumption reasons in short video platforms, consuming in short video platform (TikTok), consuming in short video platform (Kwai) and advertisements on consumption behaviour significantly affect whether short video users consume. The consumption reasons and the geographic location significantly affect the monthly cost of short video users.

The global prevalence of Chronic Kidney Disease (CKD) ranges from 9.1% to 13.4%, with China having the largest number of CKD and advanced CKD patients in Asia. Most patients choose hemodialysis (HD) due to its high safety. Still, long-term treatment may cause complications such as restless legs syndrome and skin itching, which seriously affect patients' quality of life. Recently, the Internet has gradually become the main medical and health information source. As one of the largest short-video platforms in China, TikTok is an important source for spreading health information. However, the reliability of content about hemodialysis on short-video platforms varies and lacks professional evaluation. This study aims to evaluate the content, reliability, and quality of short videos related to hemodialysis on TikTok. In May 2025, a new TikTok account was created, and the keyword "hemodialysis" was used for searching. The first 100 videos were evaluated using three scales: GQS, JAMA, and the Modified DISCERN. Relevant information from the videos was extracted and analyzed. Overall, the quality of short videos about hemodialysis on TikTok was not satisfactory. Most videos had GQS scores of 2-3, JAMA scores of 2, and Modified DISCERN scores of 2. Videos posted by health professionals had higher quality and reliability than those by non-health professionals (P < 0.05). Videos with diverse presentation forms had significantly higher GQS, JAMA, and Modified DISCERN scores than monotonous presentation forms (P < 0.05). Some variables, such as likes and duration, comments, and scale scores, showed no correlation, while the rest were positively correlated (P < 0.05). This study shows that the overall quality and reliability of short videos related to hemodialysis on TikTok are low, but videos posted by medical professionals and those with diverse presentation forms are of better quality. It is recommended that when users search for relevant health information on short-video platforms, they should prioritize watching videos released by qualified healthcare professionals with verified identity badges.

This study examines user behavior evolution in the 5G short video ecosystem using a V‑SIbR dynamic model based on evolutionary game theory. It integrates system dynamics to nonlinearly couple network parameters like latency and bandwidth with behavioral variables such as interaction frequency and strategy selection. Experiments show that user interaction grows exponentially when end‑to‑end delay is below 20 ms, with a strategy switching rate 2.3 times that of linear models. The paper proposes a collaborative optimization mechanism for network slicing and behavioral strategies, achieving Pareto optimality in bandwidth allocation and user QoE through a multi‑agent game architecture. Compared with static models, this dynamic framework increases peak user interaction capacity by 43.2% and accelerates equilibrium convergence by 37.5% under high concurrency. It validates cross‑layer synergy and advances information ecosystem research from static analysis to dynamic evolutionary modeling, supporting intelligent decision‑making for 5G short video systems.

With the booming development of short video platforms, the interaction between new media and rural image provides a new perspective for the implementation of rural revitalization strategies. Based on the media context theory, this paper adopts the content analysis method to disassemble and analyze the content of the "Three Rural Issues" short videos and their comment areas on the TikTok platform. It is found that the short video platform effectively conveys farmers' life, rural environment, and agricultural activities with the help of media technology, which to a certain extent shapes the public's positive impression of the countryside. Meanwhile, in the rural media context constructed by short videos, the public's social interaction behavior has also changed, endowing the rural image with new contemporary meanings.

In recent years, with the popularity of short video platforms, more and more peo-ple tend to use short videos to share their lives. In the catering industry, many phenomenal pop videos created by many catering brands are continuously shared on the short video platform, which has brought about a doubling of brand reve-nue. In order to specifically explore the relationship between short videos and ca-tering marketing, in this paper, we first design a questionnaire and collected hun-dreds of samples. Then, based on the samples, we analyze the users’ preferences for catering brands and related short video attributes. We also analyze the correla-tion between user attributes, sharing behavior, and customer engagement. Finally, we establish a discriminant model, a machine learning method, to predict users’ sharing and visiting behaviors according to their attributes. The experimental re-sults show the effectiveness of our method.

For many computer graphics tasks such as segmentation, tracking or retargeting, algorithms are designed to allow user interaction. For real-world applications, tools which give users some form of control are often preferred over fully automatic ones. In 3D reconstruction, however, algorithms are typically non-interactive and errors are corrected after reconstruction in generic 3D modeling software. In this contribution, we discuss fundamental algorithmic considerations regarding interactivity in 3D reconstruction and we outline an optimization-based reconstruction framework which allows the incorporation of interactive tools as energy terms.

With the rapid development of short video platforms, they are gradually changing the way information is disseminated and public opinion is guided. To explore the role of short videos in guiding public opinion, this study mainly analyzes data from third-party data platforms and short video media accounts to reveal the mechanism of short videos on the evolution of public opinion. A detailed statistical analysis of the content of relevant videos on the short video platform was conducted, including the number of video views, the number of comments, and their changing trends; An in-depth analysis was conducted on the videos and comments released by self-media and mainstream media. Through content analysis, the study evaluated the communication characteristics of these media in guiding public opinion, including the selective dissemination of information, emotional tendencies, and the shaping of public cognition. The research results show that short video platforms play a significant role in guiding public opinion, and their dissemination characteristics and content selection have a profound impact on the formation and development of public opinion. In particular, self-media and mainstream media play a key role in guiding public opinion. They play a leading role in shaping public opinion through different communication strategies and content presentation.
