Today's interfaces for time-scaled audio replay have limitations especially regarding highly interactive tasks such as skimming and searching, which require quick temporary speed changes. Motivated by this shortcoming, we introduce a new interaction technique for speech skimming based on the so called rubberband metaphor. We propose an "elastic" audio slider which is especially useful for temporary manipulation of replay speed and which integrates seamlessly into standard interface designs. The feasibility of this concept is proven by an initial user study.

Time-compressed audio replay is a very useful feature for skimming speech data. However, common user interfaces for this task usually lack the flexibility and interactivity known from interfaces for visual data browsing. In this paper, we introduce a new interface design which enhances and complements existing approaches for speech skimming. By combining time-compressed audio replay with the concept of elastic interfaces, we make speech skimming more similar to navigation in visual documents and thus, particular useful for highly interactive tasks such as review or search for information.

Being able to visually scan a document that contains a recorded lecture is essential for the usability of such files. In addition, flexible and easy interaction and navigation functionality should be provided to the students in order to improve the overall learning experience. In this paper we discuss the issues involved in these tasks and present a new interaction design that highly improves usability. First, we describe common approaches for browsing, navigating, and reviewing recorded lectures. Then we introduce a new interface design which supports higher interactivity and solves some of the most common problems with regular approaches for these tasks.

A new approach for interactive video browsing is de-scribed. The novelty of the proposed approach is the flexi-ble concept of interactive navigation summaries. Similar to time sliders, commonly used with standard soft video play-ers, navigation summaries allow random access to a video. In addition, they also provide abstract visualizations of the content at a user-defined level of detail and, thus, quickly communicate content characteristics to the user. Naviga-tion summaries can provide visual information about both low-level features but even high-level features. The concept fully integrates the user, who knows best which navigation summary at which level of detail could be most beneficial for his/her current video browsing task, and provide him/her a flexible set of navigation means. A first user study has shown that our approach can significantly outperform stan-dard soft video players- the state-of-the art ”poor man’s” video browsing tool. 1.

Automatic recording and capturing of live lectures and presentations has been explored and evaluated by various research projects since the mid 90s and has meanwhile been adapted by a number of commercial systems. Here, we discuss and summarize "Authoring on the Fly" (AOF) which is a special incarnation of this idea. The purpose of this paper is to give an overview of the AOF approach, the experience we have obtained and the requirements we have identified during its development over the last few years as well as to report on current and future research issues involved.

this paper is to introduce a new interface and interaction design for interactive audio skimming which is particularly useful for searching and navigating speech documents. The approach builds on our previous work which is summarized in Section 2 together with a general discussion of audio skimming. Section 3 describes how this approach can be extended to improve speech skimming, in particular when trying to move backwards in order to re-listen to some previously heard parts of a file. Section 4 reviews related works and puts them in relationship to our approach. Section 5 concludes the paper with a short summary and an outlook on future work

In this position paper, I argue that mobile video has the potential to become the next killer application. However, in order to achieve this it is not enough to just transfer the traditional video and TV experience to handheld devices. Instead, adaptations on the contents should be done and sophisticated tools for replay and interaction have to be offered. I start with an informal introduction using examples which illustrate the potential of mobile video and limitations of current approaches. Then, I present three examples of what has to change in order to make mobile video successful: First, offer different content, second, adapt the way in which the content is presented and third, provide better interfaces and browsing functionality. Finally, I present some examples of our own research which addresses the latter issue, i.e. improving the usability of mobile video by providing an advanced interface design and a better interaction experience.
Audio-Visual Data Skimming for E-Learning Applications

Using multimedia documents for learning puts specific demands on the user interface. Users want to be able to quickly skim audio-visual data in order to locate relevant information, skip parts of minor interest, reset replay to interesting positions, etc. In this paper we propose a new interface design which extends common media player interfaces by offering a new way for interactive, synchronised audiovisual data browsing. This approach allows users to skim multimedia documents at arbitrary speed and granularity levels with immediate visual and acoustic feedback.

ecent studies confirm that mobile video Ruse on handheld devices is quite different from watching TV in your living room. 1 For instance, assume you are standing at the bus stop, waiting for the 10-minute bus ride that will take you home from work. While waiting, you want to quickly view the latest evening news show, which you downloaded to your mobile device just before you left your office. Once you’re on the bus, you want to quickly go to the one news report that seems the most interesting to you, because you don’t have enough time to watch the whole news show. Shortly before you arrive, you want to take a quick look at the weather forecast. Because
