Assessment of end-user response to sports highlights extraction for personal video recorders

摘要

We tested our previously reported sports highlights playback for personal video recorders with a carefully chosen set of sports aficionados. Each subject spent about an hour with the content, going through the same basic steps of introduction, trying out the system, and follow up questionnaire. The main conclusion was that the users unanimously liked the functionality very much even when it made mistakes. Furthermore, the users felt that if the user interface were made much more responsive so as to quickly compensate for false alarms and misses, the functionality would be vastly enhanced. The ability to choose summaries of any desired length turned out to be the main attraction.
