Open Learner Models (OLM) show the learner model to users to assist their self-regulated learning by, for example, helping prompt reflection, facilitating planning and supporting navigation. OLMs can show different levels of detail of the underlying ...

Empirical studies of adaptive annotation in the educational context have demonstrated that it can help students to acquire knowledge faster, improve learning outcomes, reduce navigational overhead, and encourage non-sequential navigation. Over the last ...

As a new paradigm of e-commerce, collaborative online shopping fulfills online consumers' needs to shop with close ones in a social and collaborative environment. While previous e-commerce research and practice mainly focus on consumers' individual ...

Tactile displays can be used without demanding the attention from the human visual system, which makes them attractive for use in wayfinding contexts, where visual attention should be directed at traffic and other information in the environment. To ...

Current in-car navigation systems provide only a limited level of adaption to the driver and driving conditions. The driver's actual information need while interacting with the navigation interface is not taken into account. This paper aims at ...

In context-aware ubiquitous learning environment, finding out an optimal learning path for each student in real time to maximize the learning performance is important. In addition, many studies also indicated and confirmed that personalization is ...

Navigating unfamiliar places is a common problem people face, and there is a wealth of commercial and research-based applications particularly for mobile devices that provide support in these settings. While many of these solutions work well on an ...

Web browsers provide only little support for users to revisit pages that they do not visit very often. We developed a browser toolbar that reminds users of visited pages related to the page that they currently viewing. The recommendation method combines ...

User interest in topics and resources is known to be recurrent and to follow specific patterns, depending on the type of topic or resource. Traditional methods for predicting reoccurring patterns are based on ranking and associative models. In this ...

A traditional library is a social place, however the social nature of the library is typically lost when the library goes digital. This paper argues social navigation, an important group of social information access techniques, could be used to ...

Adaptive link annotation is one of the most popular adaptive educational hypermedia techniques. It has been widely studied and demonstrated its ability to help students to acquire knowledge faster, improve learning outcomes, reduce navigation overhead, ...

Large displays are rapidly proliferating in public spaces, and could therefore be an attractive resource to support nomadic users in such contexts, e. g. by providing additional screen real estate or by augmenting services delivered through a mobile ...

This paper analyzes problems encountered by our team while creating an educational digital library of program examples. We present approaches to resolving these problems, and evaluations of the suggested approaches.

This paper outlines work in progress towards using information structure maps as a graphical means of informing the reader of his/her position in a hypertext array, and of the rhetorical intent of any given utterance. The graphical navigation aids ...

This paper reports on extensions to a decision-theoretic location-aware shopping guide and on the results of user studies that have accompanied its development. On the basis of the results of an earlier user study in a mock-up of a shopping mall, we ...

Trails are a well-established concept to assist users in navigating through information spaces. However, most existing trail-based systems focus only on the World Wide Web and not on the users' overall information space, including corporate intranet ...

Many websites offer their users a lot of freedom to navigate through a large hyperspace. Some sites offer navigation or orientation support in the form of (complete or partial) site maps or guided tours. Some sites also use adaptive hypermedia ...

We are exploring a class of decision-theoretic handheld systems that give a user personalized advice about how to explore an indoor area in search of products or information. An initial user test in a simple mockup of a shopping mall showed that even ...
