New online stores and digital distribution methods have led to the development of alternative monetization models for video-games, such as free-to-play games with advertisements. Although there are many games using such models, until now the effect on the player experience from such interruptions has not been studied. In this controlled experiment, we requested that participants (N=236) play one of three different versions of a platformer game with: 1) no interruptions, 2) 30-second video advertisements, and 3) a multiple-choice questionnaire. We then evaluated the effects on the player experience. The study shows differences in their experiences, namely in: competence, immersion, annoyance, affects, and the reliability of the questionnaire answers. The contribution of this work is to identify which player experience variables are affected by interruptions, which can be valuable for selecting the business model and guiding the game design process.

Werkgevers in de Europese Unie gebruiken draagbare technologie, zoals smartphones, om er preventief voor te zorgen dat hun bedrijf geen besmettingshaard wordt. Door bron- en contactonderzoek en tracking van werknemers proberen zij dat te bereiken. Maar hoe zit dit in relatie tot de Europese AVG-regels? Stefania Marassi van de Haagse Hogeschool stelt dat er strikte voorwaarden moeten zijn om deze technologie te mogen gebruiken.

Research showed that more than 30% of patients with Posttraumatic Stress Disorder (PTSD) do not benefit from evidence- based treatments: Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) or Eye Movement Desensitization and Reprocessing (EMDR). These are patients with prolonged and multiple traumatization, with poor verbal memory, and patients with emotional over-modulation. Retelling traumatic experiences in detail is poorly tolerated by these patients and might be a reason for not starting or not completing the recommended treatments. Due to lack of evidence, no alternative treatments are recommended yet. Art therapy may offer an alternative and suitable treatment, because the nonverbal and experiential character of art therapy appears to be an appropriate approach to the often wordless and visual nature of traumatic memories. The objective of this pilot study was to test the acceptability, feasibility, and applicability of trauma-focused art therapy for adults with PTSD due to multiple and prolonged traumatization (patients with early childhood traumatization and refugees from different cultures). Another objective was to identify the preliminary effectiveness of art therapy. Results showed willingness to participate and adherence to treatment of patients. Therapists considered trauma-focused art therapy feasible and applicable and patients reported beneficial effects, such as more relaxation, externalization of memories and emotions into artwork, less intrusive thoughts of traumatic experiences and more confidence in the future. The preliminary findings on PTSD symptom severity showed a decrease of symptoms in some participants, and an increase of symptoms in other participants. Further research into the effectiveness of art therapy and PTSD is needed.
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.
