Designing to Support Workspace Awareness in Remote Collaboration using 2D Interactive Surfaces

Increasing distributions of the global workforce are leading to collaborative workamong remote coworkers. The emergence of such remote collaborations is essentiallysupported by technology advancements of screen-based devices ranging from tabletor laptop to large displays. However, these devices, especially personal and mobilecomputers, still suffer from certain limitations caused by their form factors, that hinder supporting workspace awareness through non-verbal communication suchas bodily gestures or gaze. This thesis thus aims to design novel interfaces andinteraction techniques to improve remote coworkers’ workspace awareness throughsuch non-verbal cues using 2D interactive surfaces.The thesis starts off by exploring how visual cues support workspace awareness infacilitated brainstorming of hybrid teams of co-located and remote coworkers. Basedon insights from this exploration, the thesis introduces three interfaces for mobiledevices that help users maintain and convey their workspace awareness with their coworkers. The first interface is a virtual environment that allows a remote person to effectively maintain his/her awareness of his/her co-located collaborators’ activities while interacting with the shared workspace. To help a person better express his/her hand gestures in remote collaboration using a mobile device, the second interfacepresents a lightweight add-on for capturing hand images on and above the device’sscreen; and overlaying them on collaborators’ device to improve their workspace awareness. The third interface strategically leverages the entire screen space of aconventional laptop to better convey a remote person’s gaze to his/her co-locatedcollaborators. Building on the top of these three interfaces, the thesis envisions an interface that supports a person using a mobile device to effectively collaborate with remote coworkers working with a large display.Together, these interfaces demonstrate the possibilities to innovate on commodity devices to offer richer non-verbal communication and better support workspace awareness in remote collaboration

Investigating the Impact of Co-located and Distributed Collaboration Using Multi-touch Tables

With the intention to study the role of new interfaces in multi-user applications, multi-touch tabletops are investigated to examine if they effectively aid their users in working together synchronously. Multi-player games are selected as a case of collaborative work. Early studies of distributed multi-touch tabletops did not cover the HCI related aspects associated with multi-player games, especially in distributed configuration. The performance, collaboration, and usability aspects of HCI are studied in this research. A simple multi-player maze game has been designed and implemented over two connected and physically separated multi-touch tabletops. The aim of this work is to investigate the effects of distribution on players performance, collaboration, and usability of multi-player games over multi-touch tabletops, compared to playing in a co-located condition. Groups of participants have been randomly selected and assigned to play the game in pairs under two conditions: co-located where two players are playing the game on the same table, and distributed where they are playing the game but on separate tables. The collected data is statistically analysed to test for differences between the two conditions, as well as the differences of the strength of the correlation between the underlying factors. The results indicate that, in general, the differences are not significant for such type of applications if a simple and efficient communication mechanism is provided for the players in the distributed condition. Players expressed almost the same level of usability engagement and enjoyment for the two conditions. This may have a strong impact on the HCI aspects when designing such type of applications on the future

A conversation centric approach to understanding and supporting the coordination of social group-activities

Despite the widespread and large variety of communication tools available to us such as, text messaging, Skype, email, twitter, Facebook, instant messaging, GroupMe, WhatsApp, Snapchat, etc., many people still routinely find coordinating activities with our friends to be a very frustrating experience. Everyone, has at least once, encountered the difficulties involved with deciding what to do as a group. Some friends may be busy, others may have already seen the movie that the others want to see, and some do not like Mexican food. It is a challenge everyone has faced and continue to face. This is a result of system designers and researchers primarily focusing on understanding and supporting workplace coordination. This workplace bias has led to an assumption that the same technologies employed to facilitate workplace coordination can easily transfer to social coordination. This has created a divergence between how people actually communicate and coordinate for social reasons versus how the systems and technologies developed to support such coordination and communication are designed. As a result, researchers and designers are faced with dearth of knowledge about how to design and research systems that support people engaging in coordination and communication for more social reasons. This dissertation moves beyond previous work, both academic and commercial, which has either focused on providing structured and process oriented communication and coordination support or on the creation of yet another text chat. This research focuses on a narrower aspect of social communication and coordination, specifically, the problem of social group-activity coordination. Generally, this is the stuff people do to coordinate going out to dinner or the movies with a group of friends. This area has been under researched and as personal experience informs, poorly supported. This dissertation contains four main contributions. First, a diary study of 37 young adults aged 18 to 28 investigated the current social group-activity coordination practices resulting in an expansion of the knowledge about how social groups coordinate social group-activities and what technologies people use and why. Second, via iterative design and testing following a research through design methodology the design space for social group-activity coordination is explored over multiple design iterations. This results in the design and instantiation of a social group-activity coordination support tool improving understanding of the design requirements of tools that support social group-activity coordination. Third, a quantitative survey which confirmed many of the findings discovered during the dairy study. Fourth, the tool is evaluated in a laboratory study with 84 participants during 21 sessions. This study finds that using the conversation centric design perspective presented in this dissertation it is possible to reduce information overload and support consensus building. Also, the features provided are overwhelmingly desired with 91.4% of the participants desiring the ability and interface to make suggestions about important activity details (vs open chat) and two-thirds of the participants reporting they would prefer to use this tool over text messaging. The combination of all these different investigations into social group-activity coordination extends the knowledge about how to improve the support of social group-activity coordination and move beyond the process and systems oriented perspectives and towards conversation centric designs

Online Deliberation: Design, Research, and Practice

Can new technology enhance purpose-driven, democratic dialogue in groups, governments, and societies? Online Deliberation: Design, Research, and Practice is the first book that attempts to sample the full range of work on online deliberation, forging new connections between academic research, technology designers, and practitioners. Since some of the most exciting innovations have occurred outside of traditional institutions, and those involved have often worked in relative isolation from each other, work in this growing field has often failed to reflect the full set of perspectives on online deliberation. This volume is aimed at those working at the crossroads of information/communication technology and social science, and documents early findings in, and perspectives on, this new field by many of its pioneers.

Building and Maintaining Trust in Virtual Teams as a Competitive Strategy

Many virtual team leaders lack strategies to build and maintain trust among virtual team members, which affects performance and productivity. The purpose of this exploratory single case study was to provide organizational leaders with information about the strategies that virtual team leaders use to build and maintain trust among virtual team members to enhance job performance. Cognition-based and affect-based theories of interpersonal relationships were used as a conceptual framework. In-depth, semistructured electronic interviews were conducted with 10 virtual team leaders of a multinational global organization specializing in management consulting and technology services that has headquarters in Dublin, Ireland. Interview data and documents from virtual team memos and progress reports were content analyzed with NVivo software, and member checking was used to validate transcribed data. Two major thematic categories emerged from data analysis (a) the need for effective organizational and leadership skills and (b) strategies for building and maintaining trust among virtual team members. Recommendations include reevaluating the hiring processes of virtual team leaders and members, providing adequate cross-cultural training to virtual team leaders and members, creating effective strategies for interpersonal relationships, and investing in communication technologies that foster face-to-face collaboration. Building and maintaining trust among virtual team members helps increase team performance and productivity. Implications for social change include promoting social stability, reducing projects\u27 failure, and improving the bottom line
