Many information structures are represented as two-dimensional networks (connected graphs) of links and nodes. Because these network tend to be large and quite complex, people often perfer to view part or all of the network at varying levels of detail. <italic>Hierarchical clustering</italic> provides a framework for viewing the network at different levels(More)
Navigating and viewing large information spaces, such as hierarchically-organized networks from complex realtime systems, suffer the problems of viewing a large space on a small screen. Distorted-view approaches, such as fisheye techniques, have great potential to reduce these problems by representing detail within its larger context but introduce new(More)
In this paper we describe an empirical investigation of the utility of several perceptual properties of motion in information-dense displays applied to notification. Notification relates to awareness and concerns how dynamic information is communicated from the system to the user. The results show that icons with simple motions, termed moticons, are(More)
Notification systems attempt to deliver current, important information to the computer screen in an efficient and effective manner. All notification systems require that the user attends to them to at least some degree if they are to succeed. Examples of notification systems include instant messaging systems, system and user status updates, email alerts and(More)
A home-based intelligent energy conservation system needs to know what appliances (or loads) are being used in the home and when they are being used in order to provide intelligent feedback or to make intelligent decisions. This analysis task is known as load disaggregation or non-intrusive load monitoring (NILM). The datasets used for NILM research(More)

1. ABSTRACT Visualizing information in user interfaces to complex, largescale systems is difficult due to an enormous amount of dynamic data distributed across multiple displays. While graphical representation techniques can reduce some of the cognitive overhead associated with comprehension, current interfaces suffer from the over-use of such(More)
Data surrounds each and every one of us in our daily lives, ranging from exercise logs, to archives of our interactions with others on social media, to online resources pertaining to our hobbies. There is enormous potential for us to use these data to understand ourselves better and make positive changes in our lives. Visualization (Vis) and visual(More)
Many information systems are represented as twodimensional networks of links and nodes. Because these networks tend to be large and quite complex, people often prefer to view part or all of the network at varying levels of detail. Hierarchical clustering provides a framework for viewing the network at different levels of detail by superimposing a hierarchy(More)
