Additionally, many consumers suffer ever-increasing time limitations when browsing for a particular item on a website. Users can become frustrated and stressed when they are unable to find those items due to poor information scent, or semantic cues that are meant to lead to their goal. This paper presents and tests a theoretical model to predict how information scent can reduce the amount of stress that consumers experience when seeking information under time constraints. The study also demonstrates the relationships between information scent, time constraints, stress, performance and attitudes toward the website. Results indicate that while high information scent is an important design goal, scent can only be assessed by taking the user’s task into account

Nearly every download involves privacy messages that request permissions to access information such as contact, calendar, and location information. Recent cases have revealed that users are often surprised when they discover the permissions they have granted, which implies that not everyone reads them carefully. In this paper we propose a research agenda focusing on the decisions that users make about those permissions requests. Several theories provide promising antecedents to explain acceptance of privacy permissions. Nine propositions are presented, with three from each research bases from social, economic, and cognitive perspectives. The research agenda thus is a combination hybrid social/economic/cognitive approach. The agenda complements extant research that has focused on privacy c...

In considering non-transactional outcomes—specifically brand attitude formation and information dissemination—one finds that two literature streams emerge, although they present different recommendations. First, cognitive attitude formation research recommends designing interfaces to promote an efficient experience that takes less time and requires less movement among webpages. On the other hand, the mere exposure literature recommends that longer durations and more exposure to related ideas should improve non-transactional outcomes. To understand the relationship between these two perspectives, we tested related hypotheses in a within-subjects observational experiment with a follow-up survey 10 days later. Building on theory regarding task charact...

The current membership is 3965, which is over 50% saturation of the overall population of an estimated 7000 IS academics worldwide

Meanwhile, a parallel HCI community was formed in 2001 within the Association of Information Systems (AIS SIGHCI) community. While some researchers have already bridged these two HCI subdisciplines, the history and core values of these respective fields are quite different, offering new insights for how we can move forward together to sustain the future of HCI research. The main goal of this workshop is to begin building a bridge between these two communities to maximize the relevance, rigor, and generalizability of HCI research.

Our new context includes completely new ways of developing, acquiring, and using software, which in turn has drastically changed the notion of participation. Today's world faces a more mature and ambitious set of users' processes, needs, and expectations, which has engendered fascinating and exciting challenges to developers' ability to understand and cope with the new user-centered environment. The changes are numerous. Outsourcing or purchasing off-the-shelf software has isolated users from developers and has extended the context of user participation from development to systems implementation and configuration. New revolutionary challenges have also appeared with web-based, mobile and ubiquitous systems, introducing potentially very large and geographically-distributed user bases. In addition, many contemporary systems are designed for consumer-users, who use them both during the work day as well as at home and even in leisure activities. Selecting and contacting these users may be very challenging. The user population has also widened to include new groups of people with varying ages, education, and interests (Druin, 2002; Vodanovich et al., 2010) posing new challenges for participation. Furthermore, new development approaches such as open source and end-user software development require complete reconsideration of the concept of user participation (Barcellini et al., 2008; Syrjänen, 2007). Another recent trend has been to hire or rely on different kinds of intermediaries to 'represent the users' in system development (Cooper and Bowers, 1995), such as usability or user-centered/interaction/user experience design specialists, ethnographers or change agents (Iivari et al., 2009; Karasti, 2001; Markus and Mao, 2004). Their emergence in system development has raised new challenges as well, relating e.g. to legitimizing their work both from the viewpoint of the designers and the users (Iivari, 2006).

To foster the development of SIGs with the unique perspective only available from our discipline, AIS funded the first group of six SIG proposals. The funding is designed to provide seed money for the development of electronic resources such as web sites, listserves, and on-line discussion groups. In the long run, SIGs are expected to enhance their offerings with conference minitracks, newsletters, and directories. Some SIGs will offer workshops, calls for papers in special issues of journals, working papers, electronic bibliographies, tutorials, conferences, refereed journals, and pointers to research tools and industry contacts. The six proposals described in detail in this article include Agent-Based
