The continuous advancement of Natural User Interfaces is allowing the development of novel and creative ways to support collocated collaborative work in a wide range of areas, including teaching and learning. In terms of Learning Analytics (LA), the use of interactive surfaces and Tangible User Interfaces can offer unique opportunities for automati...
Conference Paper
Learning Analytics (LA) dashboards help raise student and teacher awareness regarding learner activities. In blog-supported and inquiry-based learning courses, LA data is not limited to student activities, but also contains an abundance of digital learner artefacts, such as blog posts, hypotheses, and mind-maps. Exploring peer activities and artefa...
Conference Paper
Large interactive displays and surfaces are useful modalities for visualizing big multi-dimensional data sets. They can offer simultaneous views on different facets of the data which lead to an efficient and effective environment for data exploration and analysis. While every data analyst and enthusiast can benefit from these advantages, large inte...
Conference Paper
Targeted advertising reaches users based on various traits, such as demographics or behaviour. However, users are often reluctant to accept ads. We hypothesise that users are more open to targeted advertising if they can inspect, control and thereby understand the process of ad selection. We conducted a between-subjects study (N=200) to investigate...
Conference Paper
The adequate emotional state of students has proved to be essential for favoring learning. This paper explores the possibility of obtaining students’ feedback about the emotions they feel in class in order to discover potential emotion patterns that might indicate learning fails. This paper presents a visual dashboard that allows students to track...

The collection and management of learning traces, metadata about actions that students perform while they learn, is a core topic in the domain of Learning Analytics. In this paper, we present a simple architecture for collecting and managing learning traces.We describe requirements, different components of the architecture, and our experiences with...
Article
Full-text available
Learning Analytics is about collecting traces that learners leave behind and using those traces to improve learning. Dashboard applications can visualize these traces to present learners and teachers with useful information. The work in this paper is based on traces from an inquiry-based learning (IBL) environment, where learners create hypotheses,...

Conference Paper
Full-text available
One of the challenges when designing an electronic health record is the generational difference between general practitioners (GPs), which is especially noticeable when working with mobile devices. We discuss a paradigm shift we discovered when a mobile health record was designed using a user-centered design approach with graduated GPs and evaluate...
Conference Paper
The use of computational tools in the humanities for science 2.0 practices is steadily increasing. This paper examines current research practices of a group of philosophers studying the history of philosophical concepts. We explain the methodology and workflow of these philosophers and provide an overview of tools they currently use in their resear...

Analyzing a conference, especially one as young and focused as LAK, provides the opportunity to observe the structure and contributions of the scientific community around it. This work will perform a Scientometric analysis, coupled with a more in-depth manual content analysis, to extract this insight from the proceedings and program of LAK 2013. Au...
Conference Paper
In this paper, we present the findings from a field study that quantifies the different engagement phases of an interactive public display: from noticing interactivity and the first reaction to it, to actually interacting with the screen and expressing interest in a campaign. For this purpose, we developed an interactive public display for a real-l...

Due to recent technical developments, urban systems generate large and complex data sets. While visualizations have been used to make these accessible, often they are tailored to one specific group of users, typically the public or expert users. We present Touching Transport, an application that allows a diverse group of users to visually explore p...
Conference Paper

This paper presents an exploratory study about two language learning MOOCs deployed in the UNED COMA platform. The study identifies three research questions: a) How does activity evolve in these MOOCs? b) Are all learning activities relevant?, and c) Does the use of the target language influence?. We conclude that the MOOC activity drops not only d...

Conference Paper
Reading scientific papers is a core research activity, and helps researchers to be aware of fundamental contributions and latest trends. However, the exponential growth of scientific literature increases the complexity of evaluating what is relevant to read and why. To research how this issue can be tackled, we designed, implemented, and evaluated...
Conference Paper
Full-text available
Involving all stakeholders in the design process is often seen as a necessity from both a pragmatic and a moral point of view [1]. This is always a challenging task for designers and stakeholders and therefore many participatory design methods have been developed to facilitate such a design process. The traditional participatory design methods, how...
