Usability Study on the User Interface Design of Streaming Service Applications

Abstract: Streaming service applications allow users to watch programs across devices anytime and anywhere, and their share is increasing. In order to understand the usability of existing streaming service applications, this study selected three representative streaming service Applications in the market, namely IQIYI, Netflix, and Disney+. Download the paid version of the streaming service applications for the Android platform. Six operation tasks are designed according to users' common functions, namely, selecting the film, playing the fast-forward function, adding the film to the playlist, finding the recorded history, confirming the user’s account, and downloading the film. The experimental equipment was Xiaomi Tablet Pad5, the operating environment was a general university classroom, the participants were invited by convenience sampling. A total of 31 participants (M=19.7; SD=2.54), 16 males and 15 females, were enrolled in the university departments of Chinese Culture University and National Taipei University of Education. The experiment was conducted by filling out basic information, System Usability Scale (SUS), and subjective scale after tasks. The experimental results were divided into qualitative and quantitative parts, and the quantitative part was checked by one-way ANOVA. All the generated results are summarized as follows: (1) The search window is based on the user's needs, so do not set the keywords of the advertisement and do not push the advertisement window during the operation process to avoid affecting the user's experience. (2) Video download button can be set under the video preview window, and the width of the button can be set to the same width as the preview window for the convenience of the participant. (3) The interface can be customized to add or remove items and categories that users like. (4) For unknown functions and buttons, simple icons or explanations can be provided to facilitate participants to fully utilize the available functions on the interface. (5) Future work can increase the number of participants or conduct A/B tests on the uncorrected version of the interface after the correction to verify the effect of the correction.
