VisPod: A Visual Audio Player for Content Exploration

Current audio player interfaces generally provide brief information such as title and duration time and support basic control functions including play, pause, rewind, and forward. These features alone are not sufficient for certain user tasks, such as quickly finding a previously-visited location or browsing the main topics covered before listening. We present VisPod, a novel visual audio player interface to visually display main topics and keywords extracted from the uploaded transcript. VisPod supports overviewing the audio content in advance, navigating through topics, and browsing the content of each topic. An informal user study suggests that its features were perceived to be useful.
