While feedback is frequently emphasized as a crucial principle of presentation courses in higher education, previous studies revealed that teachers outperform peers in terms of impact on students’ development of oral presentation competence. Further, presentation research showed that the lack of quality of peer feedback can be considered as an essential argumentation for the identified differences in effect. Follow-up field experiments demonstrated that Virtual Reality (VR) can be considered as a valuable alternative feedback source for developing public speaking skills, since this technology is able to simulate real-life presentation situations as well as to deliver feedback from the VR system to the individual learner. Recent technological developments allowed to convert quantitative information from VR systems into qualitative feedback messages that directly relate to the standards for high-quality feedback. If students are able to individually interpret the feedback messages without the intervention of a human feedback source, it could enrich the quality of feedback in peer and self-learning and further increase students’ oral presentation competence development. This chapter provides a synthesis of the literature in presentation research with the aim to construct a research agenda on computer-mediated feedback in VR for peer learning in this field. Further, two recent VR experiments in presentation research are discussed with the aim to effectively construct feedback messages in VR for improving peer learning.

Trying to control multiple computers in live performances is a challenging task. Often computers intercommunicate using fixed or manual parameters. However when projects expand across many devices this is hard to maintain. Especially in situations where the parameters tend to change. We propose a new protocol which facilitates flexibility and autonomous setups in an orchestrated environment.
This review of meta-analyses of outcome studies of adults receiving Computer-Based Health Education (CBHE) has two goals. The first is to provide an overview of the efficacy of CBHE interventions, and the second is to identify moderators of these effects. A systematic literature search resulted in 15 meta-analyses of 278 controlled outcome studies. The meta-analyses were analysed with regard to reported (overall) effect sizes, heterogeneity and interaction effects. The results indicate a positive relationship between CBHE interventions and improvements in health-related outcomes, with small overall effect sizes compared to non-computer-based interventions. The sustainability of the effects was observed for up to six months. Outcome moderators (31 variables) were studied in 12 meta-analyses and were clustered into three categories: intervention features (20 variables), participant characteristics (five variables) and study features (six variables). No relationship with effectiveness was found for four intervention features, theoretical background, use of internet and e-mail, intervention setting and self-monitoring; two participant features, age and gender; and one study feature, the type of analysis. Regarding the other 24 identified features, no consistent results were observed across meta-analyses. To enhance the effectiveness of CBHE interventions, moderators of effects should be studied as single constructs in high-quality study designs. http://www.journalofinterdisciplinarysciences.com/ https://www.linkedin.com/in/leontienvreeburg/
Many lithographically created optical components, such as photonic crystals, require the creation of periodically repeated structures [1]. The optical properties depend critically on the consistency of the shape and periodicity of the repeated structure. At the same time, the structure and its period may be similar to, or substantially below that of the optical diffraction limit, making inspection with optical microscopy difficult. Inspection tools must be able to scan an entire wafer (300 mm diameter), and identify wafers that fail to meet specifications rapidly. However, high resolution, and high throughput are often difficult to achieve simultaneously, and a compromise must be made. TeraNova is developing an optical inspection tool that can rapidly image features on wafers. Their product relies on (a) knowledge of what the features should be, and (b) a detailed and accurate model of light diffraction from the wafer surface. This combination allows deviations from features to be identified by modifying the model of the surface features until the calculated diffraction pattern matches the observed pattern. This form of microscopy—known as Fourier microscopy—has the potential to be very rapid and highly accurate. However, the solver, which calculates the wafer features from the diffraction pattern, must be very rapid and precise. To achieve this, a hardware solver will be implemented. The hardware solver must be combined with mechatronic tracking of the absolute wafer position, requiring the automatic identification of fiduciary markers. Finally, the problem of computer obsolescence in instrumentation (resulting in security weaknesses) will also be addressed by combining the digital hardware and software into a system-on-a-chip (SoC) to provide a powerful, yet secure operating environment for the microscope software.
Beweegrichtlijnen geven aan hoeveel beweging nodig is voor een goede gezondheid van jong tot oud. Voor een gezonde leefstijl van kinderen zijn bewegen, samen spelen, samen leren en samen werken van groot belang, maar dat geldt ook voor ouderen. Picoo brengt het belang van bewegen en samenzijn bij elkaar. Dat zorgt voor een goede ontwikkeling van het kind, het welzijn van ouderen en het verstevigen van het bewegen en samenzijn in de maatschappij. Project: Actief Plezier met Picoo: Jong en Oud in Beweging! Vraag: Draagt Picoo bij aan meer beweging en verbinding tussen kinderen en ouderen door samen te bewegen? Doel: Het inzetten van Picoo leidt tot meer samen beweging, waardoor welzijn van ouderen en ontwikkeling van het kind en meer beweging wordt vergroot. Methode: Mixed method observatieonderzoek /survey/kort gesprek Kinderen tot 18 jaar en senioren 65 plus met een zorgvraag T0: kinderen en ouderen krijgen uitleg over het gebruik van Picoo Interventie: Picoo is een controller en spelcomputer ineen, ontwikkeld om kinderen (maar ook volwassen) interactief buiten te laten spelen.6 Tijdens de actieve games heeft elke deelnemer een eigen controller. De controllers staan met elkaar in verbinding. T1 Tijdens het spel wordt d.m.v. een observatielijst gekeken hoe jong en oud reageren op het samen spelen met Picoo. T2 Na het spel geven kinderen en ouderen door middel van Visual Analogue Scale (smileys) wat hun ervaringen zijn. T3 Na het spel gaan kinderen en ouderen kort met elkaar in gesprek over hun ervaringen Uitvoering: Interdisciplinaire mix van studenten Verpleegkunde, Fysiotherapie, Mens en Techniek en Social Work Eindproduct: Nieuwe testcase en input voor doorontwikkeling Picoo richting verbinding jong en oud. Kennis over mogelijkheden/ervaringen over verbinding door beweging wordt gedissemineerd naar de praktijk en onderwijs. Resultaten worden gerapporteerd en gepubliceerd op relevante sites zoals bijvoorbeeld kenniscentrum sport en bewegen, zorginstellingen en scholen.
Creating and testing the first Brand Segmentation Model in Augmented Reality using Microsoft Hololens. Sanoma together with SAMR launched an online brand segmentation tool based on large scale research, The brand model uses several brand values divided over three axes. However they cannot be displayed clearly in a 2D model. The space of BSR Quality Planner can be seen as a 3-dimensional meaningful space that is defined by the terms used to typify the brands. The third axis concerns a behaviour-based dimension: from ‘quirky behaviour’ to ‘standardadjusted behaviour’ (respectful, tolerant, solidarity). ‘Virtual/augmented reality’ does make it possible to clearly display (and experience) 3D. The Academy for Digital Entertainment (ADE) of Breda University of Applied Sciences has created the BSR Quality Planner in Virtual Reality – as a hologram. It’s the world’s first segmentation model in AR. Breda University of Applied Sciences (professorship Digital Media Concepts) has deployed hologram technology in order to use and demonstrate the planning tool in 3D. The Microsoft HoloLens can be used to experience the model in 3D while the user still sees the actual surroundings (unlike VR, with AR the space in which the user is active remains visible). The HoloLens is wireless, so the user can easily walk around the hologram. The device is operated using finger gestures, eye movements or voice commands. On a computer screen, other people who are present can watch along with the user. Research showed the added value of the AR model.Partners:Sanoma MediaMarketResponse (SAMR)
