Task-based User-System Interaction
No full textIn current electronic environments, the ever- increasing amount of personal information, means that users focus more on managing their information rather than using it to accomplish their objectives. To overcome this problem, a user task-based interactive environment is needed to help users focus on tasks they wish to perform rather than spending more time on managing their personal information. In this paper, we present parts of our on-going work on task-based user-system interaction, which highlights the need for a shift from an information-centric to a task-centric environment. More precisely, we look into issues relating to modeling user tasks that arise when users interact with the environment to fulfill their goals through these sets of tasks
Podcasting in the classroom: involving students in creating podcasted lessons
No full textThis paper describes an academic experience of podcasting, which involved a group of students of a course on multimedia communication and human-computer interaction both as users of the university’s podcasting service, and as creators of podcasted lessons. The evaluation of the effect on student performance and data from student satisfaction surveys provide encouraging
results
Designing for Tasks in Ubiquitous Computing: Challenges and Considerations
No full textThe traditional desktop computing paradigm has had major successes. It also should be noted that we are in a day and age where many good computer and device users are increasingly finding themselves being required to perform their activities not in offices/desktops but in real-world settings. Ubiquitous computing can make possible in the real-world setting what would have otherwise been impossible through desktop computing. However, there is a world of difference between the real-world and the desktop settings. The move from the desktop to the real-world settings raises various issues when we consider the nature of tasks that the ubiquitous devices/applications would be expected to support and the real-world context in which they will be used. A careful study of the nature of tasks in ubiquitous computing can make some design requirements in the development of ubiquitous applications more evident. This chapter proposes ubiquitous application design and evaluation considerations emerging from a deeper understanding of the nature of tasks in ubiquitous computing.</jats:p
Doing the single person study in human computer interaction (HCI) / Fariza Hanis Abdul Razak and Alan Dix
Full text linkThis paper presents how a single person study can be done in the field of Human Computer Interaction (HCI). This single person study was explored using a participant observation method known as Friendship Observation that utilises more personal data gathering tools such as diary studies, text messages and personal emails. Since interpretation of the data was done based on the research-subject relationship, some ethical issues related to the reliability, and validity of the data were raised. Despite this criticism, this type of study can offer some potential benefits to HCI community such as a methodology for a user-centred design and designing affective interaction
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
