This paper presents a subjective quality assessment of swipe delay patterns in short video streaming, revealing that user QoE is affected by delay duration, frequency, and temporal position within a session. They found that delays of 8+ seconds cause dissatisfaction and that late-session delays are more detrimental than early ones. Based on these findings, they propose a new QoE model that predicts user experience from swipe delay characteristics, outperforming existing models.
Turns out, users care more about late-session swipe delays than early ones when binging short videos.
Short video streaming platforms have gained immense popularity in recent years, transforming the way users consume video content. A critical aspect of user interaction with these platforms is the swipe gesture, which allows users to navigate through videos seamlessly. However, the delay between a user's swipe action and the subsequent video playback can significantly impact the overall user experience. This paper presents the first systematic study investigating the effects of swipe delay on user Quality of Experience (QoE) in short video streaming. In particular, we conduct a subjective quality assessment containing 132 swipe delay patterns. The obtained results show that user experience is affected not only by the swipe delay duration, but also by the number of delays and their temporal positions. A single delay of eight seconds or longer is likely to lead to user dissatisfaction. Moreover, early-session delays are less harmful to user QoE than late-session delays. Based on the findings, we propose a novel QoE model that accurately predicts user experience based on swipe delay characteristics. The proposed model demonstrates high correlation with subjective ratings, outperforming existing models in short video streaming.
