Gesture interaction with rich TV content in the social setting

The appearance of new immersive TV content has increased the interactive possibilities presented to the viewers. Increased interactivity is seen as a valuable feature in viewing richer television content, but new functionalities are limited by what can be done naturally and intuitively using available devices like remote controls. Therefore, new interaction techniques, such as visual gestures control systems, have appeared aiming to enhance the viewers’ viewing experience. In this work we begin uncovering the potential and challenges of gesture interaction with ultra high definition video for people watching TV together. As a first step we have done a study with a group of people interacting with such content using a gesture-based system in the home environment.Peer ReviewedPostprint (published version

Towards Effective Industrial Robot Fleet Visualization for Remote Service Applications

In recent years, advances in sensors, Internet and communication technologies opened many promising opportunities for remote services of industrial robots. With remote service applications, potential problems in robot systems can be detected before they happen, and prevented pro-actively avoiding costly production shut-downs. However, to be able to effectively perform remote service operations, remote support engineers need to analyse vast amounts of information. For a remote support engineer to be able to manage such amount of data, effective data visualization is crucial. Based on field studies and collected needs of support engineers working with industrial robots, we have designed and developed a prototype, i.e. one possible solution of an effective industrial fleet visualization, applied on the overheated robots use case. The initial validation of the prototype showed the benefits of such visual data presentation, as well as future directions

Frame Rate Exclusive Sync Management of Live Video Streams in Collaborative Mobile Production Environment

We discuss synchronization problem in an emerging type of multimedia applications, called live mobile collaborative video production systems. The mobile character of the production system allows a director to be present at the site where he/she can see the event directly as well as through the mixer display. In such a situation production of a consistent broadcast is sensitive to delay and asynchrony of video streams in the mixer console. In this paper, we propose an algorithm for this situation called "frame rate exclusive sync manager", which draws on existing reactive source control synchronization techniques. It relies solely on frame-rate control and maintains synchronization between live video streams while ensuring minimal delay by dynamically adapting the frame-rate of the camera feeds based on synchronization offset and network bandwidth health. The algorithm is evaluated by simulation which indicates algorithm's capability of achieving increased synchronization among live streams
