This paper describes experiments with a game device that was used for early detection of delays in motor skill development in primary school children. Children play a game by bi-manual manipulation of the device which continuously collects ac- celerometer data and game state data. Features of the data are used to discriminate between normal children and children with delays. This study focused on the feature selection. Three features were compared: mean squared jerk (time domain); power spectral entropy (fourier domain) and cosine similarity measure (quality of game play). The discriminatory power of the features was tested in an experiment where 28 children played games of different levels of difficulty. The results show that jerk and cosine similarity have reasonable discriminatory power to detect fine-grained motor skill development delays especially when taking the game level into account. Duration of a game level needs to be at least 30 seconds in order to achieve good classification results.
This paper introduces a creative approach aimed at empowering desk-bound occupational groups to address the issue of physical inactivity at workplaces. The approach involves a gamified toolkit called Workplace Vitality Mapping (WVM) (see Figure 1) designed to encourage self-reflection in sedentary contexts and foster the envision of physical vitality scenarios. This hybrid toolkit comprises two main components: A Card Game (on-site) for context reflection and a Co-design Canvas (Online) for co-designing vitality solutions. Through the card games, participants reflect on key sedentary contexts, contemplating their preferable physical vitality scenarios with relevant requirements. The co-design canvas facilitates the collaborative construction and discussion of vitality scenarios’ development. The perceptions and interactions of the proposed toolkit from the target group were studied and observed through a hybrid workshop, which demonstrated promising results in terms of promoting participants’ engagement experience in contextual reflections and deepening their systemic understanding to tackle the physical inactivity issue. As physical inactivity becomes an increasingly pressing concern, this approach offers a promising participatory way for gaining empathetic insights toward community-level solutions.
Playfulness intertwined with city-related themes, such as participatory planning and civic media are becoming more popular. In the last ten years, game designers have taken up the theme of play in relation to the urban environment. In this paper, we present a conceptual mapping of “urban play,” through the analysis of eight examples of urban games. Better conceptual tools are necessary to discuss and reflect on how games draw on, or deal with, urban issues. While urban games are diverse in medium, intent, and experience, across the spectrum analyzed in this paper, they hold the potential for various player experiences emerging through play that may be useful to designers. These are: a sense of agency and impact; feelings of relatedness and empathy; an awareness and understanding of complexity, perspective-taking and scenario-building, and either planning or taking action. The conceptual mapping offers scholars and practitioners a more nuanced vocabulary for designing games and playful interventions that might be used to tackle societal issues that either require or could benefit from genuine public involvement as engaged citizens.

Measuring and designing user experience in retail and gaming virtual reality using a CAVE set-up In this project we designed and measured user experiences in a CAVE virtual reality set-up. Virtually all studies have taken the form of experiment studies and have been conducted among consumers (in total more than 1500 consumers) who had to visit the virtual world with assignments based on which behaviour has been observed and after which a survey was conducted afterwards. The studies were carried out within the three lines of inquiry: a. Branded games / in-game advertising, revealing (positive) effects of in-game advertising on attention and attitude based on logos and faces incorporated into the games. Various applications (prototypes) have been developed that stimulate the shopping experience and the interaction between shop and consumer. (b) FMCG: studies answered the question which factors influence search and choice behaviour in the supermarket. On the basis of the studies, the clients have designed new packaging and adapted existing designs, deployed new shelf layouts, developed and implemented new Retail strategies, optimized instore communication and (e) the knowledge about consumer behaviour in the supermarket within the organization has been increased. (c) Location Based Advertising: recommendations have been made for the partners concerned and the field of work on (a) development of non-intrusive pervasive/ubiquitous advertising concepts (2nd screen, LBA, gaze-based advertising etc.), (b) development of virtual test environments and associated interaction methods and (c) exploration and review of theoretical models for persuasive communication and behavioural influence.
