An important issue of the demographic change in the German population is the maintenance and promotion of the employability of aging workforces. However, there are hardly any suitable concepts or usable tools available to realize this goal. Possible approaches should push the individual strengths of the aging workers to the foreground and…

Purpose: The purpose of the paper is to describe the practical experience of managing e-books in an academic library. Design/methodology/approach: An overview of the three main e-book collections used (netLibrary, Taylor & Francis, and Ebook Library via Dawson) is provided, along with details such as the acquisition, cataloguing and…

Considers search histories and their role in human information seeking and identifies potential application areas for history information to enhance information-seeking user interfaces. Reports results related to supporting mental model development and task integration, based on a study of legal information seeking. (LRW)

The "Technology Outlook Australian Tertiary Education 2013-2018: An NMC Horizon Project Regional Analysis" reflects a collaborative research effort between the New Media Consortium (NMC) and Open Universities Australia to help inform Australian educational leaders about significant developments in technologies supporting teaching,…

A multipoint, multimedia conferencing system called FocusShare is described that uses IPv6/IPv4 multicasting for real-time collaboration, enabling video, audio, and group awareness information to be shared. Multiple telepointers provide group awareness information and make it easy to share attention and intention. In addition to pointing with the…

Purpose: Social navigation is an emerging trend for navigation in hypermedia. With social navigation, users can be guided through large volumes of learning content by cues which integrate the browsing history of past users. Earlier papers have shown that social navigation is suitable for navigation not only in classic hypermedia but also in…

Humans draw on their stereotypic beliefs to make assumptions about others. Even though prior research has shown that individuals respond socially to media, there is little evidence with regards to learners stereotyping and categorizing pedagogical agents. This study investigated whether learners stereotype a pedagogical agent as being…

Describes two database systems in a law enforcement agency: one is a legacy, text-based system with cumbersome navigation; the newer system is a graphical user interface with simplified navigation. Discusses results of two user studies that showed personnel preferred the older more familiar system and considers implications for system design and…

Describes seven design principles found in computer games that contribute to the creation of more usable applications. Provides examples from several games to illustrate these principles ("attract mode," clearly stated goals, brief instructions, transparency, performance coaching, "training wheels," and consistent feedback). Argues that games set…

Purpose: The purpose of this study was to determine if older adults are capable and willing to interact with a computerized exercise promotion interface and to determine to what extent they accept computer-generated exercise recommendations. Design and Methods: Time and requests for assistance were recorded while 34 college-educated volunteers,…

The Cognitive Tutor Authoring Tools (CTAT) support creation of a novel type of tutors called example-tracing tutors. Unlike other types of ITSs (e.g., model-tracing tutors, constraint-based tutors), example-tracing tutors evaluate student behavior by flexibly comparing it against generalized examples of problem-solving behavior. Example-tracing…

Analyzes interfaces supporting spoken, pen-based, and multimodal input for their effectiveness in interacting with interactive map systems. Results identified performance difficulties with speech-only map interactions that declined substantially when people could interact multimodally. Analyses also indicated that map displays can be structured to…

Of 45 adults over 50 who had computer experience, 44% reported difficulty reading screens, 53% were frustrated by complex software, and 27% had difficulty with the mouse. The physical characteristics of aging should be considered in designing special software features such as dynamic text resizing and menu buttons instead of pull-down menus. (SK)

Discusses visualization of legal information using a tool for temporal information called "LifeLines." Explores ways "LifeLines" could aid in viewing the links between original case and direct and indirect case histories. Uses the case of Apple Computer, Inc. versus Microsoft Corporation and Hewlett Packard Company to…

Intelligent Tutoring Systems (ITSs) that employ a model-tracing methodology have consistently shown their effectiveness. However, what evidently makes these tutors effective, the cognitive model embedded within them, has traditionally been difficult to create, requiring great expertise and time, both of which come at a cost. Furthermore, an…
