Web search is often viewed as a solitary task; however, there are many situations in which groups of people gather around a single computer to jointly search for information online. We present the findings of interviews with teachers, librarians, and developing world researchers that provide details about users ’ collaborative search habits in sharedcomputer settings, revealing several limitations of this practice. We then introduce CoSearch, a system we developed to improve the experience of co-located collaborative Web search by leveraging readily available devices such as mobile phones and extra mice. Finally, we present an evaluation comparing CoSearch to status quo collaboration approaches, and show that CoSearch enabled distributed control and division of labor, thus reducing the frustrations associated with shared-computer searches, while still preserving the positive aspects of communication and collaboration associated with joint computer use.

Groups of users often have shared information needs – for example, business colleagues need to conduct research relating to joint projects and students must work together on group homework assignments. In this paper, we introduce WeSearch, a collaborative Web search system designed to leverage the benefits of tabletop displays for face-to-face collaboration and organization tasks. We describe the design of WeSearch and explain the interactions it affords. We then describe an evaluation in which eleven groups used WeSearch to conduct real collaborative search tasks. Based on our study’s findings, we analyze the effectiveness of the features introduced by WeSearch. Author Keywords Interactive tables, surface computing, tabletop computing,

This paper introduces a novel and creative approach for coupling multimedia art with a non-conventional distributed humancomputer interface for multi-user interactive entertainment. The proposed MobiLenin system allows a group of people to interact simultaneously with a multi-track music video shown on a large public display using their personal mobile phones, effectively empowering the group with the joint authorship of the video. The system is realized with a client-server architecture which includes server-driven real-time control of the client UI to guarantee ease of use and a lottery mechanism as an incentive for interaction. Our analysis of the findings of an empirical user evaluation conducted in a true environment of use shows that the MobiLenin system is successful, addressing many of the challenges identified in the literature. The proposed system offers a new form of interactive entertainment for pubs and other public places, and the underlying architecture provides a framework for realizing similar installations with different types of multimedia content.

This paper presents a novel middleware for developing flex-ible interactive multi-surface applications. Using a scenario-based approach, we identify the requirements for this type of applications. We then introduce Substance, a data-oriented framework that decouples functionality from data, and Shared Substance, a middleware implemented in Sub-stance that provides powerful sharing abstractions. We de-scribe our implementation of two applications with Shared Substance and discuss the insights gained from these ex-periments. Our finding is that the combination of a data-oriented programming model with middleware support for sharing data and functionality provides a flexible, robust so-lution with low viscosity at both design-time and run-time.

Falling hardware prices and ever more displays being connected to the Internet will lead to large public display networks, potentially forming a novel communication medium. We envision that such networks are not restricted to display owners and advertisers anymore, but allow also passersby (e.g., customers) to exchange content, similar to traditional public notice areas, such as bulletin boards. In this context it is crucial to understand emerging practices and provide easy and straight forward interaction techniques to be used for creating and exchanging content. In this paper, we present Digifieds, a digital public notice area we built to investigate and compare possible interaction techniques. Based on a lab study we show that using direct touch at the display as well as using the mobile phone as a complementing interaction technology are most suitable. Direct touch at the display closely resembles the interaction known from classic bulletin boards and provides the highest usability. Mobile phones preserve the users ’ privacy as they exchange (sensitive) data with the display and at the same time allow content to be created on-thego or to be retrieved.

(e) Six projectors create a large, high-resolution image. (d) (e) Co-located collaborative Web browsing is a relatively common task and yet is poorly supported by conventional tools. Prior research in this area has focused on adapting conventional browsing interfaces to add collaboration support. We propose an alternative approach, drawing on ideas from tabletop interfaces. We present WebSurface, a novel tabletop interface for collaborative Web browsing. WebSurface explores two design challenges of this approach: providing sufficient resolution for legible text; and navigating through information. We report our early experiences with an exploratory user study, in which pairs of collaborators gathered information using WebSurface. The findings suggest that a tabletop approach for collaborative Web browsing can help address limitations of conventional tools, and presents beneficial affordances for information layout.

We report the design, implementation and evaluation of Wordster, a word finding game played with public displays and mobile phones. The study shows how collaborative gaming in the single player mode enhances social interaction via co-location and spectator view. The usability and playability of the mobile multiplayer mode targeted for competitive gaming between players and realized by coupling a public display and a personal mobile phone into a distributed interface were found good in a controlled user evaluation. However, the adoption of the mobile multiplayer mode in an uncontrolled evaluation “in the wild ” was poor, challenging the findings of the controlled user evaluation.

Abstract. The eCampus project at Lancaster University is an inter-disciplinary project aiming to deploy a wide range of situated displays across the University campus in order to create a large per-vasive communications infrastructure. At present, we are conducting a series of parallel research activities in order to investigate how the pervasive communications infrastructure can support the daily needs of staff, students and visitors to the University. This paper introduces one of our current research investigations into how one is able to mediate spontaneous interaction with the pervasive display infrastructure through camera equipped mobile phones (i.e. smart devices). 1

This paper presents a novel interaction metaphor for Multiple Display Environments (MDEs) called lightweight personal bindings. This approach enables users to easily bind edges from one display to another and move seamlessly between displays. The goal of this work is to support collocated collaboration in a dynamic multi-display environment while accommodating users’ personal preferences. With lightweight personal Copyright is held by the author/owner(s). CHI 2006, April 22–27, 2006, Montréal, Québec, Canada.

This approach also helps manage changes in the environment as devices enter, move, or leave.
