Title: Potential influences to collaboration

Abstract:The aim of this study is to investigate if a game could be used for examining influential factors to collaboration. For the assessment of children, existing methods were found to be flawed. A point and click collaborative game focused on children is developed having two controllers linked to each other in order to make collaboration the key for better performance in the game. To focus the participants on the game they were motivated for a competition with an incentive. The method is found to be capable of distinguishing collaborative groups from non-collaborative groups in terms of game performance. Three potential influential factors to collaboration have been examined: eye contact, distance between players and the presence of a dominant player. Twenty eight dyads, recruited at a primary school in the ages group ten to twelve years, have been tested for collaboration. The method itself was found to be promising however, with the given sample size none of the examined factors were found to be of significant influence. Possible explanations other than the amount of test subjects include, the length interval of the examined distances and the research time per dyad. Further research is required to find statistical evidence. The outcomes of this study can be valuable to behavioral psychologists for it provides a new method of testing influences to collaboration.

Title: The influence of technological interface metaphor entailments on application expectations

Abstract: In this study, we investigated whether the entailments that interface metaphors provide have an influence on the expectations users have about the applications’ functionality and if their subjective computer experience plays a role in these expectations. The findings from our survey do not support our hypothesis that using metaphors influences these expectations in a negative way.

Title: New Ways in Thinking about Nature Relatedness: Can Sonic Feedback from Human-Plant Interaction Increase Feelings of Connectedness to Plants?

Abstract: In an age of incredible human technological progress and urban growth, one must wonder – what implications does this have on our ecological identities. The field of ecopyschology has, for years now, investigated the existing levels of nature connectedness in humans. However, most studies are based on self-report, are placed outside any particular environmental context and lack ways of affecting such identities.
This study provides a specific context to investigating nature relatedness – the context of human-plant interaction, or horticulture, and further analyses whether sonic feedback from such interaction can affect subjects’ various feelings of connectedness to plants. The design, prototype and experiment were tested for three days in the Hortus Botanicus, Leiden with an overall sample group of 30 subjects.

Title: Faster performance means better understanding?
User’s Performance and Attitude versus Understanding of Data in Interactive Information Visualization

Abstract: Interactive information visualization (InfoVis) has become very popular and commonly seen in our everyday life. Studies on interaction in InfoVis have also been extended in many aspects: new interaction techniques, design principles and evaluation. However, very few researches mentioned people’s understanding of data in their interaction evaluation. This paper aims at confirming some typical evaluation measurements, namely task performance time and subjective attitude, and their relationship with the understanding of the visualized data.
We conducted an experiment involving two different interaction techniques (WIMP and non-WIMP) on a same InfoVis case with the same task. Through the experiment, people’s understanding of data, together with task performance time and subjective attitude were measured. The collected data showed a strong correlation in the WIMP interaction condition, where task performance time is positively correlated to the understanding of data. But since our results did not display any correlation between variables elsewhere, we suggest that it is better for future studies on interaction in InfoVis to include understanding of data as one of the evaluation measures.

Title: Telling a Story With a Graph-Based Interface: Case Study at Teyler’s Museum

Abstract:
In this study a combination of interactive storytelling of museum artifacts and a graph-based visual interface is investigated. A web application is created in which a user can navigate between 22 different stories which are linked on a subject basis.Therefore, the main research question focusses on the experience of a presentation of these linked stories in a GUI, for which specifically a graph is used. At the same time we try to understand how users explore these interlinked stories and how they react to their visual presentation. The particular behaviour of encountering a visual bottleneck or an obstacle in the graph is observed from our experimental data. Results of 39 participants show that based on selection procedures it is possible to distinguish groups of users which are interested in reading the stories and those who are less interested. Paths that users probe are described. In addition, there does seem to be a drop-off in readers after a visual bottleneck and multiple choice question(s) in the application. One of the near-end nodes has been visited surprisingly often, indicating that participants may go for a visual path towards the end instead of a practical path through the story-lines.

Title: Developing an Augmented Reality application to promote an extended concept of cognition in education

Abstract:
The ever decreasing size and price of computer parts seems to be leading to computing power becoming ubiquitous. Similar to technology such as pen and paper, computing power becomes intertwined with our problem solving processes in such ways that it becomes invisible. This development has, and will have, enormous influence on our cognitive profiles. The field of education however, has barely changed to cope with this change in cognitive profiles.  While developments in information technologies are changing how we learn in many ways, we believe it is essential to rethink what we should learn in this perspective of increasing availability and accessibility of computing power.
This research reviews an extended concept of cognition, in which technological elements can actually be part of the cognitive process. We suggest this view as a framework to discuss the goals of education and the technological aids that can be used to reach these goals. To raise this discussion, a mobile application is developed which shows the potential of Augmented Reality techniques to display context-sensitive information, which can be incorporated in the problem solving process.
