Showing papers in "Interacting with Computers in 2011"

TL;DR: A new pragmatic framework for socio-technical systems engineering (STSE) is proposed which builds on the (largely independent) research of groups investigating work design, information systems, computer-supported cooperative work, and cognitive systems engineering.

TL;DR: The study suggests that the proposed UX Curve method can be used as a straightforward tool for understanding the reasons why user experience improves or worsens in long-term product use and how these reasons relate to customer loyalty.

TL;DR: It is argued that a successor science for standpoint epistemology has already come into being within the field of HCI, though it is perhaps not recognized as such by its practitioners.

TL;DR: Female survivors living in a domestic violence shelter interviewed about their experiences with technology reported that they were harassed with mobile phones, experienced additional harassment (but also support) via social networking sites, and tried to resist using their knowledge of security and privacy.

TL;DR: This paper explores one route, drawing on Queer Theory to look at resistance to computer formalisation of identity through queering, to apply the oblique route to design of a range of technologies that help users define themselves.

TL;DR: The goal in doing so is to argue for the importance of a more direct treatment of gender in HCI and move towards a feminist theory for HCI.

TL;DR: A synthesis of practices of criticism derived from analytic philosophy of aesthetics and critical theory is offered, including the introduction of five core claims from this literature and the outline of four perspectives that constitute a big-picture view of interaction criticism.

TL;DR: This paper investigates real password use in the context of daily life with a high level set of password guidelines, along with suggestions for mechanisms to support creating, encoding, retrieving and executing multiple passwords.

TL;DR: This paper formulates a framework that encompasses validity, reliability, sensitivity, adequacy and complexity of metrics in the context of four scenarios where the metrics can be used, and demonstrates that it is feasible and shows the findings when it is applied to seven existing automatic accessibility metrics.

TL;DR: The results deepen current understanding of tools use in connecting older people with their social circles and the interaction issues most of them encounter when using ICT.

TL;DR: An end-to-end investigation into gender differences with spreadsheet software showed gender differences in feature usage, feature-related confidence, and tinkering (playful exploration) with features.

TL;DR: It is suggested that people attend to the justifiability of hedonic and pragmatic attributes rather than to their impact on experience, which has a number of implications, reaching from how to elicit requirements to general strategic considerations when designing (for) experiences.

TL;DR: It is shown that transitions between scanning and reading behavior in eye movement patterns and the amount of text processed may be an implicit indicator of the current task type facets.

TL;DR: It is found that the perceptions of three product attributes and technology acceptance variables (the beliefs of Perceived Ease of Use, Perceived Enjoyment and Perceived Usefulness, and Intention to Use) are separate underlying psychological dimensions.

TL;DR: A feminist reflexivity is brought to HCI, drawing on the work of Judith Butler and her concepts of peformativity, citationality, and interpellation, to show how SNS structures and policies help shape the subject and hide the contingency of subject categories.

TL;DR: It is suggested that rather than system response time being task- or expectation-focused, instead interactions with a computer fall into two categories: control tasks and conversational tasks.

TL;DR: The ViMos framework as discussed by the authors is an infrastructure to generate context-powered information visualization services dynamically, providing functionality to make decisions about what and how available information can be offered, as well as to offer personalized information to the user.

TL;DR: A surprisingly strong effect of positive expectations on subjective post-experiment ratings was revealed: the participants who had read the positive review gave the device significantly better post-Experiment ratings than did the negative-prime and no-prime groups.

TL;DR: This paper compares the effectiveness of two different Contextual Cues techniques, Wedge and Scaled Arrows, and investigates the scalability of the considered visualizations, finding that even a small increase in the number of off-screen objects negatively affected user performance in terms of accuracy.

TL;DR: The Game Discourse Analysis (GDA) which discerns between information flow and game discourse was found to have potential as a communication tool for multidisciplinary design teams and the impact of this GDA supported manipulation on engagement (curiosity) and learning was tested.

TL;DR: A standardised scale to measure usability in e-commerce websites using item response theory (IRT) is developed and opens a new field of research in the ergonomics of interfaces with respect to the development of scales using IRT.

TL;DR: A novel gaze-driven remote camera control with an implemented prototype is presented, which follows a simple and natural design principle: ''Whatever you look at on the screen, it moves to the centre!''.

TL;DR: If the identified critical roles of the drivers are not accounted for, a migration to a fully automated metro system can affect the quality of service and raise safety issues, according to the conclusion of this research.

TL;DR: This work proposes a generic and application-independent framework for activity recognition of users interacting with a computer interface that uses Layered Hidden Markov Models (LHMM) and is based on eye-gaze movements along with keyboard and mouse interactions.

TL;DR: The development of a new, web-based, graphical authentication mechanism called ImagePass introduces a novel feature based on one-time passwords that increases the security of the system without compromising its usability, and whether user training via mnemonic instructions improves the graphical password recognition rate.

TL;DR: It is concluded that the aggregated evaluation results for blind, low vision and motor impaired users can be used to approximate the Evaluation results for mobile web users.

TL;DR: In depth analysis showed close relationships between the different foci of interaction and the learning process: engaging with a tangential activity in a exploratory interaction engendered cognitive engagement with domain related concepts; while engaging with technology to understand the basics of the system's functioning could facilitate higher levels of conceptual abstraction.

TL;DR: The findings suggest that the use of an in-built tutorial reduces emotional and technological barriers to wiki editing and that controlled experiments can help in discovering how aspects of the system experience can be designed to affect usability and anxiety towards editing wikis.

TL;DR: A scientific technique called concept mapping is proposed to identify the external variables that should be kept in mind while designing an eLearning tool so that improvements can be programmed to increase its utility in the teaching activities prior to its use.

TL;DR: In this paper, the authors investigated how much the Internet was used to obtain information about everyday problems with a legal dimension, who used it, how it was used and how successful respondents were in searching for information online.
