If everyone says time is relative, why is it still so rigidly defined? There have been many attempts to address the issue of coordinating schedules, but each of these attempts runs into an issue of rigidity: in order to negotiate an event, a specific time must be designated in advance. This model is inherently poor at accommodating life's unpredictability. Kairoscope looks at time from a human perspective, focusing on time as made up of a series of events, rather than simply a series of events in time. By removing our reliance on a fixed time system, events are coordinated socially and on the fly, without worrying about precision. This paper explores the creation of Kairoscope, rooted in ideas of time perception and aiming to reduce time-related stress, optimize time usage, and increase social interaction. The result is a socially-coordinated, constantly adapting, and highly malleable guide through time.

Video content has become available on an increasingly diverse set of devices and from an ever growing number of sources, creating a vast amount of choice for viewers. At the same time, the varying methods of viewing, interacting with, and sharing content have diverged. This paper introduces neXtream, a new approach to delivering video by integrating multiple devices, content sources, and social networks. This concept is developed following research in social television and converged applications, providing both personalization features and social interaction. NeXtream delivers video by dynamically generating streams of video customized to a viewer, while facilitating a common dialog between users around the content, creating both a user- and community-centric viewing experience. NeXtream integrates smartphones, PCs, and TVs to deliver video content to viewers. The paper presents the system concept, theory, and architecture, and describes the developed prototype.
