    How will we interact with our computational environments in the next 10 years? If the past is to be any indication of the future, our hands will remain restricted to a keyboard and our eyes will remain focused on a desktop display. It is true that progress in mobile computing, computer networks, and miniaturization allows users to access information through a number of less restrictive devices (e.... View full abstract»

    Motion capture has important applications in different areas such as biomechanics, computer animation, and human-computer interaction. Current motion capture methods use passive markers that are attached to different body parts of the subject and are therefore intrusive in nature. In applications such as pathological human movement analysis, these markers may introduce an unknown artifact in the m... View full abstract»

    Many novel multimedia, home entertainment, visual surveillance and health applications use multiple audio-visual sensors and actuators. In this paper we present a novel approach for position and pose calibration of visual sensors and actuators, i.e. cameras and displays, in a distributed network of general purpose computing devices. It complements our work on position calibration of audio sensors ... View full abstract»

    This paper presents a self-reconfigurable camera array system that captures and renders 3D virtual scenes interactively. It is composed of an array of 48 cameras mounted on mobile platforms. We propose an efficient algorithm that is capable of rendering high-quality novel views from the captured images. The algorithm reconstructs a view-dependent multiresolution 2D mesh model of the scene geometry... View full abstract»

    A first step towards an understanding of the semantic content in a video is the reliable detection and recognition of actions performed by objects in the environment. This is a difficult problem due to the enormous variability in an action's appearance when seen from different viewpoints and/or at different times. In this paper we present a novel approach to representing actions that models action... View full abstract»

    This paper presents a model-based 3D object tracking system that uses an improved Extended Kalman filter (EKF) with graphics rendering as the measurement function. During tracking, features are automatically selected from the input images. For each camera, an estimated observation and multiple perturbed observations are rendered for the object. Corresponding features are extracted from the sample ... View full abstract»

    Many human activities follow a loosely defined script in which individuals assume roles. Encoding such scripts in a formal representation makes it possible to build systems that observe and understand human activity. In this paper, we first present a conceptual framework in which scripts for human activity are described as scenarios composed of actors and objects within a network of situations. We...

    A whiteboard provides a large shared space for the participants to focus their attention and express their ideas, and is therefore a great collaboration tool for information workers. However, it has several limitations; notably, the contents on the whiteboard are hard to archive or share with people who are not present in the discussions. This paper presents our work in developing tools to facilit... View full abstract»

    One of the persistent challenges in computer vision has been tracking objects under varying lighting conditions. In this paper we present a method for estimation of 3D motion of a rigid object from a monocular video sequence under arbitrary changes in the illumination conditions under which the video was captured. This is achieved by alternately estimating motion and illumination parameters using ... View full abstract»

    Radio frequency tags allow objects to become self-describing, communicating their identity to a close at hand RF reader. Our goal is to build a radio frequency identity and geometry (RFIG) transponder that can also communicate geometry, inter-tag location history or contextsensitive user annotation.

    Traditional desktop computing paradigms provide a poor interface for interacting with intelligent physical spaces. Although handheld devices are an important platform for interface agents, their displays are inadequate for many pervasive computing tasks and need to be supplemented by larger high-resolution displays. We propose the notion of augmenting indoor intelligent environments with ambient p... View full abstract»
