How to Optimize Online Lecture Video Speeding for Learning in Less Time?
2018.04 | ChineseCHI 2018
Online video-based learning is popular among the global student community. We investigate ways of leveraging Artificial Intelligence (AI) to reduce the video watching time without losing comprehension of the video content. Using an in-house designed video player prototype, we conducted an observation study to understand user behavior in adjusting the video playback rate. We present preliminary results from this study and discuss implications of our observations in designing potential AI-based solutions to semi-automatically adjust the video playing speed to reduce the watching time without affecting the users’ comprehension.
