The Influence of Interactivity on E-service Offerings: An Empirical Examination of Benefits and Risks BIBAKFull-Text 1-25
  Mauricio Featherman; Ryan T. Wright; Jason Bennett Thatcher; J. Christopher Zimmer; Richard Pak
News reports of Internet-based security breaches, identity theft, fraud, and other dangers may increase the perceived risk and decrease the perceived benefits of using electronic services (or e-services). We examine whether interactivity serves as a means to diminish the perceived risks and increase the perceived benefits of using e-services. To examine interactivity's influence on consumers' perceptions, we conducted a laboratory experiment using a simulated web-based, online payment system. When compared to a non-interactive preview of an online payment system, we found that consumers who used an interactive e-service simulation reported higher perceived involvement and authenticity as well as higher intangibility and risks of e-services. Further, we found that interactivity moderated relationships such that consumers were more likely to report higher intentions to use e-services. The paper concludes with implications for research and practice.

Designing Emergency Response Dispatch Systems for Better Dispatcher Performance BIBAKFull-Text 26-55
  Anna L. McNab; Traci J. Hess; Joseph S. Valacich
Emergency response systems are a relatively new and important area of research in the information systems community. While there is a growing body of literature in this research stream, human-computer interaction (HCI) issues concerning the design of emergency response system interfaces have received limited attention. Emergency responders often work in time pressured situations and depend on fast access to key information. One of the problems studied in HCI research is the design of interfaces to improve user information selection and processing performance. Based on cue-summation theory and research findings on parallel processing, associative processing, and hemispheric differences in information processing, this study proposes that information selection of target information in an emergency response dispatch application can be improved by using supplementary cues. Color-coding and sorting are proposed as relevant cues that can improve processing performance by providing prioritization heuristics. An experimental emergency response dispatch application is developed, and user performance is tested under conditions of varying complexity and time pressure. The results suggest that supplementary cues significantly improve performance, with better results often obtained when both cues are used. Additionally, the use of these cues becomes more beneficial as time pressure and task complexity increase.

Introduction to the AIS THCI Special Issue on Design Research in Human-Computer Interaction BIBAFull-Text 56-61
  Alan Hevner; Ping Zhang
Design Research (DR) creates, builds, and evaluates innovative artifacts such as constructs, models, methods, and instantiations as well as operational information systems. It also investigates approaches, methods, behaviors, and processes related to design. Although the design research paradigm as an engineering approach in Information Systems (IS) research has been actively discussed in recent years (Hevner et al., 2004), comparatively little design related research has made its way into the IS community by means of widely recognized and outstanding publications. Human-Computer Interaction (HCI) Research is concerned with the ways humans interact with information, technologies, and tasks; especially in business, managerial, organizational, and cultural contexts (Zhang et al., 2002). Despite the realization that it is important for HCI research to focus on all issues that occur along the lifecycles of any information and communication technology (ICT) artifacts, IS scholars have traditionally put less effort into the design and development stage and more effort into the use and impact stage (Zhang and Li, 2005; Zhang et al., 2009).
Design Principles for Special Purpose, Embodied, Conversational Intelligence with Environmental Sensors (SPECIES) Agents BIBAKFull-Text 62-81
  Douglas C. Derrick; Jeffrey L. Jenkins; Jay F., Jr. Nunamaker
As information systems increase their ability to gather and analyze data from the natural environment and as computational power increases, the next generation of human-computer interfaces will be able to facilitate more lifelike and natural interactions with humans. This can be accomplished by using sensors to non-invasively gather information from the user, using artificial intelligence to interpret this information to perceive users' emotional and cognitive states, and using customized interfaces and responses based on embodied-conversational-agent (avatar) technology to respond to the user. We refer to this novel and unique class of intelligent agents as Special Purpose Embodied Conversational Intelligence with Environmental Sensors (SPECIES) agents. In this paper, we build on interpersonal communication theory to specify four essential design principles of all SPECIES agents. We also share findings of initial research that demonstrates how SPECIES agents can be deployed to augment human tasks. Results of this paper organize future research efforts in collectively studying and creating more robust, influential, and intelligent SPECIES agents.

A Multidimensional Perceptual Map Approach to Project Prioritization and Selection BIBAKFull-Text 82-103
  Guangzhi Zheng; Vijay K. Vaishnavi
When prioritizing projects, managers usually have to evaluate multiple attributes (dimensions) of project data. However, these dimensions are usually condensed into one or two indicators in many existing analysis processes. For example, projects are commonly prioritized using a scoring approach: they are evaluated according to predefined categories, which are then aggregated into one or two priority numbers. We argue that aggregated scores may only offer a limited view of project importance. This often leads decision makers to ignore the possible differences masked by the aggregation. Following the design science research paradigm, this paper presents a visual exploration approach based on multi-dimensional perceptual maps. It incorporates human intuition in the process and maintains the multidimensionality of project data as a decision basis for project prioritization and selection. A prototype system based on the approach was developed and qualitatively evaluated by a group of project managers. A qualitative analysis of the data collected shows its utility and usability.

A Design Methodology and Implementation for Corporate Network Security Visualization: A Modular-Based Approach BIBAKFull-Text 104-132
  Andy Luse; Brian E. Mennecke; Janea Triplett; Nate Karstens; Doug Jacobson
Research surrounding visualization for computer and network security has produced differing accepted methods for adequately developing security visualization products. The current work proposes a design methodology that melds the research of the three competing frameworks for security visualization development. In addition, a product that incorporates the proposed design methodology is developed, used, and evaluated. Findings show that users of the system believe the system has increased their effectiveness at performing network security tasks and are likely to use such a system in the future.

Bringing Discourse Ethics to Value Sensitive Design: Pathways toward a Deliberative Future BIBAKFull-Text 133-155
  Fahri Yetim
Value Sensitive Design (VSD) is a comprehensive framework for advancing a value-centered research and design agenda. It provides methods for producing and evaluating a design outcome by taking human values into account. Drawing on discourse ethics, this paper first critically analyzes the status quo in VSD and identifies some gaps. These mainly concern the lack of explicit methods for supporting a deliberative and legitimate process of decision making with respect to many concerns, including the identification of stakeholders, the legitimation of common design communication, the justification of trade-offs and/or a common regulation in case of competing or incommensurable values, as well as the deliberativeness of other design decisions such as the selection of design goals and means. In addition, this paper suggests ways to move VSD toward the standards of discourse ethics by drawing on the knowledge base of critical research in the Information Systems field. In particular, the suggestions concern the inclusion of a practical method for boundary critique and different types of discourses and principles as well as discourse support methods and tools for structuring participation in a way that allows participants to deal with the plurality of values, norms, goals and means deliberatively. Finally, this paper revisits a VSD case and explores the applicability of the ideas suggested.

The Effect of Customer Service and Content Management on Online Retail Sales Performance: The Mediating Role of Customer Satisfaction BIBAKFull-Text 156-169
  Anteneh Ayanso; Kevin Lertwachara; Narongsak Thongpapanl
This paper analyzes the mediating role of customer satisfaction by studying the relationship between IT-enabled customer service and content management efforts and online sales performance. Using data on the top performing Web retailers in the U.S. based on their online annual sales, we show that the extent of retailers' efforts in online customer service and content management is positively linked to customer satisfaction, which in turn is positively related to the retailers' online sales performance. In addition to directly increasing the revenue, our results indicate that customer service and content management features can also indirectly improve the retailers' financial performance. Specifically, customer service management impacts the sales performance via the average ticket amount, while content management affects the sales via the repeat visit.

Social Networking Websites and Posting Personal Information: An Evaluation of Protection Motivation Theory BIBAKFull-Text 170-188
  Kent Marett; Anna L. McNab; Ranida B. Harris
The popularity of social networking websites among Internet users continues to grow, even though social networking remains a risk for users who do not participate with caution. Using protection motivation theory (PMT) as a theoretical lens to provide a research model, and by issuing a fear appeal to social network users about the potential threat to their privacy, this study identified perceptions and beliefs held by users that influence their behavioral responses to the imposed threats. A snowball sample survey measuring the variables conceptualized by PMT was completed by 522 social network users. A time-ordered hierarchical regression analysis of the responses showed that PMT provides explanations for both adaptive and maladaptive responses, particularly for the response of hopelessness. Implications and directions for future research in this area are offered.

Team Climate and Media Choice in Virtual Teams BIBAKFull-Text 189-213
  Kathrin Figl; Carol Saunders
As work teams become more distributed, effective computer-mediated communication is increasingly impacting their performance. This study investigates how team climate influences communication frequency among team members and their use of different communication media. Data were collected in two information systems courses offered at an Austrian university in which 50 student teams developed web-based applications and conducted usability tests. A team climate framework based on task and social orientation was used to assess the teams' performance and communication patterns. We found that both task and social dimensions of team climate were positively related to higher communication frequency as well as objective and subjective performance. Among other things, the results suggest that a task-oriented climate is especially linked to the use of e-mail, while social orientation is linked to the use of face-to-face meetings. We also found differences in communication patterns and performance across four different types of team climates (fully functioning, cozy, cold, and dysfunctional). The results underscore the importance of both task and social dimensions for a team to perform well. Our study contributes to both the academic literature that investigates factors affecting media choice and the practitioner literature that examines how to manage virtual teamwork effectively.

NFriendConnector: Design and Evaluation of An Application for Integrating Offline and Online Social Networking BIBAKFull-Text 214-235
  Felix Köbler; Suparna Goswami; Philip Koene; Jan Marco Leimeister; Helmut Krcmar
This paper describes the design and evaluation of NFriendConnector, a prototype application that allows for better integration between online and offline social networks. Online social networks are currently used to maintain and strengthen existing real-life social connections, rather than establishing ties that exist only online. However, users incur significant time and search related costs in replicating a naturally occurring social interaction using a social networking site (SNS). Therefore, there exists a gap between initiating social contact in real-life versus initiating social contact via an online social network. Using the design science paradigm, our research addresses this gap by introducing NFriendConnector. This application allows users to map their offline interactions, as and when they take place, onto their SNS presence, therefore making it possible to complement offline social interactions with SNS profile information. The prototype is implemented using Near Field Communication (NFC)-enabled mobile phones and Facebook. We evaluate the prototype in an experimental setting using expectation confirmation theory (ECT) as the theoretical framework. Findings show that NFriendConnector was able to satisfy users, therefore indicating a successful design exercise. We discuss the implications of this research in the context of current developments in online social networking.
