This article explored the perspectives of 25 patients regarding virtual reality (VR)-based rehabilitation following knee surgery and identified the important factors that allowed patients to immerse themselves in rehabilitation. Qualitative analysis of data collected via open-ended questionnaire and quantitative analysis of data from physical assessments and surveys were conducted. In the open-...

In this article we present a system that enhances content in platform game levels. This is achieved by adding particular gaming entities and adjusting their arrangement, causing consequent changes in the inherent difficulty and in path related aspects. This idea follows our prior work for the automatic creation of level environments. Starting with a primal level structure and a corresponding gr...

This paper reports on the computational analysis of thin slices of video fragments showing children that solve either easy or hard mathematical puzzles. The objective of the analysis is to determine if head movements reveal whether the children consider the puzzle to be easy or hard. Our analysis method combines a facial-expression extraction method with a nonparametric classifier. Training and...

This article presents an overview over our system for the creation of platform game levels. It consists of a framework with a generic and flexible approach that integrates most of the concepts that can be found in this type of games. In addition, some procedural techniques are employed allowing automatic level generation, dynamic difficulty adjustment, optional content creation and item gatheri...
