This study uses minimally invasive technology to monitor the emotional response of a subject during stress inducing psychological tasks. The goal of these tasks is to investigate the possibility of measuring and subsequently categorising the subject’s level of stress using biosignal devices

This paper addresses the debate regarding the respective merits of high and low fidelity prototypes, in the domain of video prototyping

Museum and art-gallery curators have long had specialist collection management systems to facilitate access to works of art that were not available to the general public. The increasing availability of aesthetic images on the World Wide Web, however, especially through museum and gallery web pages, went hand in hand with an increasing sophistication of search paradigms. Retrieval methods have, in a literal and metaphorical sense, become multi-faceted. Art image retrieval can, depending on the retrieval task, draw to a greater or lesser extent on a rich body of expert knowledge from the domain of art history. We have conducted an exploratory study analysing the use of query terms for the same set of target images among a group of art specialists and laypersons

Exponential growth of user-generated content (UGC) on the Web demands an effective way for information consumers to acquire what they need. Specialized UGC search services outperform general-purpose search engines that usually have difficulties retrieving UGC or rank them low. However, with existing UGC search services, consumers may only be able to acquire information that is related to their needs rather than the exact information what they want. In this paper, we present a novel consumer-led interactive search approach that can help consumers acquire the information they exactly want through a consumer-led interactive search process where invited information providers jointly create such information on the fly.

Recent proof-of-concept research has appeared showing the applicability of Brain Computer Interface (BCI) technology in combination with the human visual system, to classify images. The basic premise here is that images that arouse a participant’s attention generate a detectable response in their brainwaves, measurable using an electroencephalograph (EEG). When a participant is given a target class of images to search for, each image belonging to that target class presented within a stream of images should elicit a distinctly detectable neural response. Previous work in this domain has primarily focused on validating the technique on proof of concept image sets that demonstrate desired properties and on examining the capabilities of the technique at various image presentation speeds. In this paper we expand on this by examining the capability of the technique when using a reduced number of channels in the EEG, and its impact on the detection accuracy.

This paper defines the field of Child Computer Interaction. Beginning with an historical look at this field, and identifying some of the key moments in its development, the work then brings together reflection from experience, and knowledge from literature, to describe and define Child Computer Interaction.

The paper proposes a software development methodology which also employs the participatory action research (PAR) method given that PAR has been successfully employed in projects in rural communities. Arguments for this approach are provided, discussed in the context of software development for rural communities.

This paper covers the findings of a qualitative study of facial animation, in which a cohort of student animators were tasked with producing spatiotemporally configured emotional expression animations.

People are prone to errors in many aspects of life, including when entering numbers. The effects of these errors can be disastrous, for example when an incorrect number is entered when programming a medical infusion pump or when entering financial information into a system. Designing better systems may help to prevent these errors however, in order to do this we need to understand far more about the types of errors being made, and their causes. Unfortunately, there are very few documented examples of number entry errors and thus many of the studies conducted so far rely upon modelled, not real world data. This paper reports a study that was designed to elicit number entry errors and the subsequent process of creating a taxonomy of errors from the information gathered.

In this paper we describe results from an exploratory study observing infusion pump use in practice. From 31 observations of pump programming we note 10 low-level disturbances, which we conceptualise in terms of unremarkable error.

We present the results of a group interview of choreographers aimed at understanding their conceptions of how movement can be used to in live performance

A usability evaluation has been conducted to gain in-depth understanding of the usefulness and usability of HandsOnVideo and the study yields positive results. In this paper, we describe the evaluation method, report the experimental results, discuss the findings and envision possible future improvements.

The present paper starts with a crucial discussion about the imbalance between technological and human concerns in the context of human-computer interaction, an imbalance that has arisen partly from the mechanistic aspect and its impact on interaction design

This paper describes a new way of understanding Social Presence in technologically mediated communication by relating it to a well-established psychological relationship construct: Closeness. We propose a model whereby an individual’s long-term feeling of Closeness to others is influenced by communication events that are invested with a sense of Social Presence, as a function of the background level of psychological Closeness.

We present here a proposed design framework for intimate communication devices. The intention is to highlight the decisions designers have to make when coming up with new communication systems and provide a more formalised system for considering the issues involved.

While much has been written about recent successful social networking sites, this paper takes a different approach and examines vfridge, a social networking application developed 10 years ago, well before the current explosion, which, despite a vision that now seems prescient, was unsuccessful.

This study contributes to the discussion on video telephony for inter-generational family communication. We present an evaluation of 11 alternative interaction options next to the standard options “accept” or “decline” for video telephony in 10 family scenarios with 20 grandchildren and 20 grandparents.

We present Social Comics, a casual video game that allows players to act in short comic strips that they create.

The latest in the most popular head-to-head fighting video series, Super Street Fighter IV by Capcom, now features spectating functionality. Coupled with audio chat, players can both watch and participate in matches with anyone in the world. We describe a video analysis of over 36 hours of gameplay in SSF4. Our results show that players can deftly structure audio when spectating to transform gameplay in SSF4.

Prototyping is a well-studied activity for interaction designers, but its role in computer game design is relatively unexplored. The aim of this study is to shed light on prototyping in game design. Interviews were conducted with 27 game designers. The empirical data was structured using qualitative content analysis and analysed using the design version of The Activity Checklist. The analysis indicated that six categories of the checklist were significant for the data obtained. These categories are presented in relation to the data. The roles of externalization and internalization are specifically highlighted.
