In this paper, we discuss our adaptation of a single-display, single-user commercial application for use in a multi-device, multi-user environment. We wrap Google Earth, a popular geospatial application, in a manner that allows for synchronized coordinated views among multiple instances running on different machines in the same co-located environment. The(More)
In this paper we propose a new model for a class of rapid serial visual presentation (RSVP) interfaces [16] in the context of consumer video devices. The basic spatial layout "explodes" a sequence of image frames into a 3D trail in order to provide more context for a spatial/temporal presentation. As the user plays forward or back, the trail advances or(More)
Multi-touch tabletops have been the focus of significant recent study but, to date, few devices have moved from prototype to installed use. In this paper, we present observation and analysis of a subject who has used a direct-touch tabletop as his primary computing environment for the past 13 months, driving all manner of applications in a standard MS(More)
We introduce the concept of identity-differentiating widgets (iDwidgets), widgets parameterized by the identity of their user. Although multiuser applications have become more common, most support only traditional " single-user " widgets. By adding user-identity information we allow interactions with today's widgets to be dynamically customized on a(More)
Games and other forms of tabletop electronic entertainment are a natural application of the new multiuser multi-touch tabletop technology DiamondTouch [3]. Electronic versions of familiar tabletop games such as ping-pong or air hockey require simultaneous touch events that can be uniquely associated with different users. Multi-touch two-handed gestures(More)
We propose a method for power theft detection based on predictive models for technical losses in electrical distribution networks estimated entirely from data collected by smart meters in smart grids. Although the data sampling rate of smart meters is not sufficiently high to detect power theft with complete certainty, detection is still possible in a(More)
We introduce the concept of a temporal Magic Lens, a novel interaction technique that supports querying and browsing for video data. Video data is available from an increasingly number of sources, and yet analyzing and processing it is still often a manual, tedious task. A Temporal Magic Lens is an interactive tool that combines spatial and temporal(More)
