SAGE2: A New Approach for Data Intensive Collaboration Using Scalable Resolution Shared Displays
Proceedings of the 10th IEEE International Conference on Collaborative Computing: Networking, Applications and Worksharing, 2014
Current web-based collaboration systems, such as Google Hangouts, WebEx, and Skype, primarily enable single users to work with remote collaborators through video conferencing and desktop mirroring. The original SAGE software, developed in 2004 and adopted at over one hundred international sites, was designed to enable groups to work in front of large shared displays in order to solve problems that required juxtaposing large volumes of information in ultra highresolution. We have developed SAGE2, as a complete redesign and implementation of SAGE, using cloud-based and web browser technologies in order to enhance data intensive colocated and remote collaboration. This paper provides an overview of SAGE2's infrastructure, the technical design challenges, and the afforded benefits to data intensive collaboration. Lastly, we provide insight on how future collaborative applications can be developed to support large displays and demonstrate the power and flexibility that SAGE2 offers in collaborative scenarios through a series of use cases.

This paper describes the Liveboard, a large interactive display system. With nearly one million pixels and an accurate, multi-state, cordless pen, the Liveboard provides a basis for research on user interfaces for group meetings, presentations and remote collaboration. We describe the underlying hardware and software of the Liveboard, along with several software applications that have been developed. In describing the system, we point out the design rationale that was used to make various choices. We present the results of an informal survey of Liveboard users, and describe some of the improvements that have been made in response to user feedback. We conclude with several general observations about the use of large public interactive displays.
The EMSL TeleViewer: a collaborative shared computer display
Proceedings of WET ICE '96. IEEE 5th Workshop on Enabling Technologies; Infrastucture for Collaborative Enterprises, 1996
Today's desktop conferencing and groupware software often assume a serial work model in which information (pictures, documents, presentations) are prepared by one person and then disseminated to others for comments, revision, or review. However, many types of collaborative work are much more parallel, with two or more people viewing, modifying, and adding information simultaneously. Effectively supporting parallel collaborative work electronically is still a challenge because of the current serial work paradigm found in most software. One promising and, broadly applicable capability is a collaborative shared computer display (CSCD). A CSCD allows several people to simultaneously view, and possibly annotate or manipulate, a live computer display sent from a remote machine to their local computers. We have been building a prototype CSCD, the Environmental Molecular Sciences Laboratory Televiewer, which supports cross-platform display sharing between MacOS, Windows, and UNIX operating systems. The current EMSL Televiewer prototype supports display sharing of application windows, screen regions, and desktops. We are adding enhancements to the EMSL Televiewer that will provide collaborative annotations over the display, shared mouse cursorslpointer, high performance data compression, and session recording capabilities. When completed, the EMSL Televiewer will provide researchers, their collaborators, and the scientific community with a powerful tool that can by itself open up many new avenues for collaboration and will fit well with other tools to provide a comprehensive collaborative environment.
Tandem Browsing Toolkit: Distributed Multi-Display Interfaces with Web Technologies
We present the Tandem Browsing toolkit that allows developers to build multi-display and multi-user applications for pervasive displays with web technologies. Existing tools for this purpose either focus on user needs, rather than developer needs, or do not rely on open web standards. Our proxy-based toolkit allows developers to conceptualize, design and implement interfaces that orchestrate multiple devices in navigating through online content, without any modifications to user devices. We first describe the design and implementation of our toolkit, followed by a qualitative validation with web developers. Then we illustrate the functionality of the toolkit with three prototypes. We conclude with a discussion on the toolkit's characteristics and capabilities.

Large interactive displays for supporting workgroup collaboration comprise a growing area of ubiquitous computing research and many such systems have been designed and deployed in laboratory studies and research settings. Such displays face difficulties in real-world deployments, as they are often supplemental technologies as opposed to primary tools for work activities. In this work, we investigate the integration and uptake of the NASA MERBoards, shared interactive displays that were deployed to support science tasks in the Mars Exploration Rover (MER) missions. We examine the hurdles to adoption imposed specifically by the real-world circumstances of the deployment that were external to the design of the system, and explain how these concerns apply to the general deployment of shared ubicomp technologies in the real world.
Red: a framework for prototyping multi-display applications using web technologies
We present the Really Easy Displays framework (RED), a web-based platform to facilitate spontaneous interaction between devices and applications. RED provides a single abstraction for content and interaction between display types, data streams and interaction modalities, and allows developers to create multi-display applications by enabling the sharing of web document object models (DOMs) across displays. We present lessons learned from using RED in our own research, hands-on workshops with developers and interviews with long-term developers over the course of a year. We provide initial evidence that the use of web-technologies in a framework like RED can mitigate some barriers encountered in by multi-display interaction scenarios, and we propose future work to improve RED.
Enabling multi-user interaction in large high-resolution distributed environments
Future Generation Computer Systems, 2011
As the amount and the resolution of collected scientific data increase, scientists are realizing the potential benefits that large high-resolution displays can have in assimilating this incoming data. Often this data has to be processed on powerful remote computing and storage resources, converted to high-resolution digital media and yet visualized on a local tiled-display. This is the basic premise behind the OptIPuter model. While the streaming middleware to enable this kind of work exists and the optical networking infrastructure is becoming more widely available, enabling multi-user interaction in such environments is still a challenge. In this paper, we present an interaction system we developed to support collaborative work on large high-resolution displays using multiple interaction devices and scalable, distributed user interface widgets. This system allows multiple users to simultaneously interact with local or remote data, media and applications, through a variety of physical interaction devices on large high-resolution displays. Finally, we present our experiences with using the system over the past two years. Most importantly, having an actual working system based on the OptIPuter model allows us to focus our research efforts to better understand how to make such high-resolution environments more user-friendly and usable in true real-world collaborative scenarios as opposed to constrained laboratory settings.► Fundamental design aspects of collaborative large high-resolution displays. ► A fully functional interaction system based on the OptIPuter model. ► Experiences towards improvement of general usability of such environments.
Beyond the laboratory: supporting authentic collaboration with multiple displays
2008
Figure 1: An example multiple display environment. It is increasingly common to find Multiple Display Environments (MDEs) in a variety of settings, including the workplace, the classroom, and perhaps soon, the home. While some technical challenges exist even in single-user MDEs, collaborative use of MDEs offers a rich set of opportunities for research and development. In this workshop, we will bring together experts in designing, developing, building and evaluating MDEs to improve our collective understanding of design guidelines, relevant realworld activities, evaluation methods and metrics, and opportunities for remote as well as collocated collaboration. We intend to create not only a broader understanding of this growing field, but also to foster a community of researchers interested in bringing these environments from the laboratory to the real world.
