Experiences Using Large Scale Video Walls for Distance Education
No full textWe describe our experiences building and using the Rutgers Videowall, a low-cost telepresence system that has been used teaching 15 courses and colloquia. By relaxing typical spatial telepresence features, such as background continuity, we greatly reduced costs and gained flexibility in the rooms it could be deployed in. The lower costs and room flexibility enabled academic departments to use the wall, in contrast to traditional telepresence systems which remained inaccessible. We found that the Videowall’s spatial distortions did not have a significant impact on useability, as our initial survey results show that students had an overall positive experience.Technical report DCS-tr-72

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Pervasive Computing for the 99%
No full textA key limiting factor for the pervasive community has been the difficulty developing and deploying general purpose systems. Such systems should make application development easy, support a wide range of devices and sensors, and allow users to share these resources. Designing a multi-user middleware system that allows novice users to add arbitrary hardware and software raises several challenges, such as resolution between conflicting and stale data, managing data dependencies as software and hardware is changed, and tradeoffs between complexity and expressiveness in the API of such a system. We will discuss the feature set that could solve these problem, and test these features through a software implementation. We then evaluate the system after a year long deployment supporting smart office applications.Technical report DCS-TR-69
A Geometric Approach to Device-Free Motion Localization Using Signal Strength
No full textIn this work we describe and evaluate an approach to accurately infer the position in a building where human motion occurs. Our approach does not require the humans to wear any type of device. Such passive mobility localization is applicable in a wide variety of application domains, including those in security, human workflows, and systems management. We position human motion using the change in standard deviation of the received signal strength between stationary transmitters and receivers at known locations. Using a modest transmission rate of once per second, we localize the motion at 2-5 second timescales using a lines-intersecting-tiles method where each line is a straight path between a transmitter and receiver. Our algorithm returns a set of rectangular tiles where the motion has occurred. We experimentally validate our scheme in two different building environments, one containing a cluttered space and a second with a more open arrangement. We show good results for basic mobility detection, with a low number of false positives and negatives. We show that we can localize human motion with a median error of less than 20 ft. We can achieve these results with a modest density of inexpensive active RFID tags, one per 500 ft.2. We also explored how our results degrade with reduced density of transmitters and receivers, and show our mobility detection rates remain good although the geometric precision of the results degrades in line with the density of transmitters.Technical report DCS-TR-67

GRAIL: A General Purpose Real Time Localization System: Version 1.0
No full textThis paper describes a general purpose Real Time Location System (RTLS), GRAIL, version 1.0. GRAIL provides real-time, adaptable, indoor localization for wireless devices. Because GRAIL’s focus is to localize as diverse a set of devices as possible, it utilizes a centralized, anchor based approach. GRAIL defines an abstract data model for various system components to support different physical modalities and various localization algorithms. We show through real deployments that GRAIL functions over a variety of physical modalities, networks, and algorithms. Further, we found that a centralized solution has critical advantages over distributed implementations for handling privacy concerns. A contribution of this system is its universal approach: it can integrate different hardware and software capabilities within a single localization framework. The deployment of such a system in academic and research environments allows researchers to explore issues beyond algorithms and investigate effects in real deployments.
