Augmented Reality biedt unieke mogelijkheden om mensen samen te laten werken met computers. Met behulp van sensoren en slimme algoritmes herkent de computer waar de gebruiker mee bezig is en kan precies de informatie tonen die op dat moment relevant is. Dit biedt interessante mogelijkheden voor ‘on-the-job assistance’. Met de juiste software kunnen mensen ingewikkelde problemen sneller oplossen. Een aantal voorbeelden:

Every year Robin teaches an Honours Class at Leiden University. The past years this course was Learning through Virtual Reality

In the fall of 2019 I will (almost certainly) start a new course ‘Augmented Reality & Human-Computer Collaboration‘, which has its focus on how AR will affect our society and influence the future of work.

This summary of Google’s I/O 2019 event shows some of the impressive products Google is working on: new Augmented Reality functionalities, a smarter Google Assistant and cheaper Google Pixel phones.

What is really interesting about this event is the shift in the mission of the company:

“We’re moving from a company that helps you find answers to a company that helps you get things done”

This statement by CEO Sundar Pichai illustrates the developments in digital technology and the role digital products will have in our daily lives. The focus in articles on Artificial Intelligence is often on completely autonomous computer systems. The focus in this event however, is mostly on how smarter algorithms allow for more sophisticated computer interfaces for users.

Today Marleen & Robin (that’s me) visited the kick-off of the PERL group at Leiden University. An interesting afternoon! As probably everybody who attended this event, we think it’s important for students to learn the digital skills they need to create new things. That’s why we organize courses for teachers and students in Processing and CoSpaces Edu an co-organize the CoSpaces Competition!

The day consisted of several talks focusing on research that helps to teach programming skills a little better. In this post I’ll share some insights.

Met het VR Learning Lab schreven we mee aan een projectvoorstel geïnitieerd door dr. Marie Postma en haar collega’s bij Tilburg University. Afgelopen week is aangekondigd dat een NRO Comenius Senior Fellow beurs is toegekend aan dit project! Zie hier het bericht dat geplaatst is op de website van Tilburg University.

Wearing a VR headset is often seen as a rather individual experience. And indeed, the immersiveness of the experience tends to seclude you from your environment and the people surrounding you. However, there are also different, exciting forms of collaboration in Virtual Reality. Some of these can be very interesting for collaborative learning, or for solving complex problems together. In this article we’ll discuss a few interesting projects, some of which are focused on local collaboration.

On October the 11th 2017, the new edition of the Honours Class Learning through Virtual Reality will start! The course is primarily meant for bachelor students who follow an honours track at Leiden University. However, the Honours Academy allows for a few master students each year, which can be specifically interesting for Media Technology students. Please notice however that honours classes are extracurricular and cannot be counted as an elective course. They will be mentioned on your diploma though.

Bachelor students from Leiden University can register for the course on this page, master students on this page. Are you a student from another university? Please contact us, perhaps we can arrange something.

Op 28 juni 2017 mocht Robin een pitch geven voor 700 bezoekers van de Onderzoeksconferentie, georganiseerd door Kennisnet en het NRO. Hierbij een foto van Twitter en de slides van de presentatie.

Op 7 juni organiseert LiketoShare het congres ‘Leren met VR’. Robin geeft die dag een lezing met de focus op experimenteren met Virtual Reality in het hoger onderwijs. Hoe kun je op een laagdrempelige manier experimenten starten? En hoe betrek je studenten in dit proces?

Het belooft een leerzame dag te worden, met veel interessante deelnemers!

Kennisnet organiseert op 28 juni 2017 de jaarlijkse Onderzoeksconferentie, waar Robin een pitch mag geven over zijn onderzoek naar Virtual Reality in het onderwijs.

Er staat ook al een kort artikel op de website. Kom je ook naar de onderzoeksconferentie?

In opdracht van het Nationaal Regieorgaan Onderwijsonderzoek hebben we een uitgebreid literatuuronderzoek uitgevoerd over Virtual Reality en Augmented Reality in het basisonderwijs. De vraagsteller, een bestuur van een grote scholengemeenschap formuleerde voor de NRO Kennisrotonde de volgende vraag:

Wat weten we over de inzet en effectiviteit van Augmented Reality en Virtual Reality in het basisonderwijs?

Het volledige onderzoek is hier te vinden, hieronder de samenvatting van het onderzoek, zoals ook gepubliceerd op de website van het NRO.

An English version of this report will come out in the near future.

Het is nog te vroeg om harde conclusies te trekken over de effectiviteit van VR of AR in het onderwijs. Veel van de onderzoekers zijn echter positief en zien veel mogelijkheden voor deze nieuwe leermiddelen. De grootste uitdaging ligt in de ontwikkeling van goede educatieve inhoud en inbedding in lesprogramma’s.

Er is goed onderzoek verricht naar de effectiviteit van VR als leermiddel, maar het gaat dan over ‘screen-based VR’, waarbij geen headset wordt gebruikt maar een scherm. In dit onderzoek beperken we ons tot Head Mounted Display (HMD) gebaseerde Virtual Reality, waarbij wel gebruik wordt gemaakt van een headset. Dat sluit volgens ons het beste aan bij het heersende beeld van deze techniek.

Psychology researchers often require participants to be in a certain emotional state. The Focus on Emotions group does research into effective anger management and needed a way to induce anger in children in a reliable and ethical manner. Motivated by the emotional effects Virtual Reality experiences, they asked Media Technology students to create a project.

Project Anger Induction is a Virtual Reality experience that aims to induce anger in children. The Gear VR / Google Cardboard app allows users to play an enjoyable game with Jasper, our digital avatar. While he might seem like a nice, cooperative boy at first, Jasper’s true nature – a rather annoying one – shows itself over time. Through the use of Jasper, we hope to see to what extent Virtual Reality can be used to create a sense of social anger.

This project was created by the Media Technology students Nesse van der Meer and Pieter Rohrbach in cooperation with Marieke Bos and Carolien Rieffe from the research group Focus on Emotions. Robin de Lange was the supervisor of the project.

Tonight SURF will officially release their ‘Trendrapport 2016’ at the preconference of the Onderwijsdagen. Robin was honored to be the author of the chapter on Virtual Reality, together with Lieke Rensink and Jan-Paul van Staalduinen. You can download the Dutch Trendrapport here, the English version will follow in the next few weeks.

Tomorrow, on the 8th of November, Robin will give a lecture on VR & education at the same Onderwijsdagen. On both days, the DinoZapp team will be present to show the Virtual Reality game they made in collaboration with Naturalis.

As part of the Virtual Reality for Science & Education course, the student team consisting of Gosse Mol, Roos Hoefnagel and Han Lie collaborated with Naturalis and created DinoZapp. This video shows a preview of the first prototype:

For my current research I broadly explore the potential of Virtual Reality for education. As a part of this I try to form some sort of theoretical framework to describe the unique characteristics of VR as a medium and how it can be used to explain complex concepts and teach different skills.

With some googling you can find quite a few articles (both academic, popular and in-between) that describe the various ways VR could be used in education. There are even a few listicles out there, to use the parlance of our times. Now, who can resist the simplicity of a 5 point overview of this new medium and its role in learning?

I do research on the potential of Virtual Reality for education. Now, people generally find VR very exciting and because of this I get a lot of enthusiastic reactions. People can imagine all sorts of useful applications for education. Students could learn about our solar system while experiencing a space flight, or walk through ancient Rome and learn about its history.

Of course, I also receive a lot of reactions that are more critical of VR as a learning tool. We are at a point in time where there’s hardly any decisive research about learning performances in Virtual Reality. We don’t even know yet whether people will buy VR headsets. Shouldn’t we wait for these kinds of things before we invest in hardware and educational VR content? VR has been a hype before, can the technology deliver the promises that are being made?

On the 10th of March 2016 we organized the Virtual Reality for Science & Education symposium at the Scheltema Complex in Leiden. I think we can safely state the event was a great success!

Over 125 people attended the event, causing a small shortage of chairs at the busiest time of the symposium. I have seen many familiar faces, but also met a lot of interesting new people. The list of attendees included researchers, professors, high school teachers, entrepreneurs, Virtual Reality developers, policy makers and artists. I think this mix of people led to very interesting discussions, thank you all very much for your input!

During the past year I have spoken with a lot of people about the use of Virtual Reality for learning, which is the topic of my research. Surprisingly many people are really excited about this. But why is this? Why are people enthusiastic about VR in education?

Updates about the program below!

During the last few years developments in Virtual Reality have gained a lot of momentum. Almost two decades after the inevitable downfall in the hype cycle, the Oculus Rift showed that a VR headset is within reach for the average consumer. This kickstarted many new initiatives, causing an entire VR ecosystem to emerge, with small start-ups and massive corporations creating new headsets, innovative input devices, spherical cameras and loads of immersive content.

These developments open many possibilities for research and education. Realistic simulations allow police officers to safely train dangerous situations. 3D visualizations can help the design process by allowing the user to walk around in buildings that have not been built yet. But we can also think of immersive data visualizations which can be navigated spatially. Psychology researchers can use VR to measure responses to realistic environments and scenarios. Lectures about ancient Rome could be given while walking past the Colosseum and virtual classrooms could make following a MOOC into a more intense and social experience.

Symposium
To explore the possibilities of this new medium, we organize the symposium ‘Virtual Reality for Science & Education‘ on the 10th of March 2016. The symposium will start at 13:30 at the Scheltema complex in Leiden. Around 17:30 we will end the day with some drinks and Virtual Reality demonstrations.

On this day, the students from the eponymous elective research course of the Media Technology MSc. program will present the VR prototypes they have created.

The plenary program will have speakers from different backgrounds: Virtual Reality developers, scientists who use VR in their research and educators who experiment with VR in the classroom.

On 12 January 2016 I gave a guest lecture at the Education & ICT course at Utrecht University. Great to give students their first VR experience and discuss the potential uses for the field of education.

Some pictures by Casper Hulshof:

In the spring of 2015 I taught the course Embodied Vision together with Dan North. The course was part of the Media Technology MSc. program.

In the lectures given by Dan the students learned about special effects and illusionism in cinema and how this is used in the service of narrative and spectacle. In the following workshops I gave we explored to what extent the visual effects used in film are usable for creating immersive experiences in Virtual Reality. The studens identified differences and similarities between film and contemporary Virtual Reality. For their final project for the course the students created cinematic VR projects which experimented with e.g. stop-motion, green screens, interactive gaze-controlled video and the dolly zoom effect.

Below you can find some of my slides for the course.

In May 2015 the Gratama Stichting and Leids Universiteitsfonds announced that my research project into the possibilities of Virtual Reality for the field of education will receive the Gratama research grant. Prof. dr. Jaap van den Herik helped me with the application procedure, the research will be part of my PhD work supervised by prof. dr. Bas Haring.

The research project includes an elective course where 30 students will explore the potential of Virtual Reality for science and education by creating experimental VR prototypes. More details about the course in the e-Studiegids.

My research project was mentioned in the Leiden University newsletter and Mare.

On March 24th 2015 I gave a talk at the Art of Neuroscience symposium in the beautiful Eye in Amsterdam. More information about this yearly event can be found here.

In my talk I presented the Virtual Reality visualization of live EEG data I created with my team mates Eva Delincakova and Bert Spaan at the Hack the Brain hackathon in May 2014. I discussed the potential of Virtual Reality for immersive data visualization and how this could be used in the field of education.

On the 19th of June 2014 at 10.00, I’ll teach a workshop for the Embodied Vision course of the Media Technology MSc. program. Below you can find a short description of the workshop and the assignment. After the workshop I’ll post a summary of what we’ve discussed.

Embodied Vision Workshop: Augmented and Virtual Reality with Unity3D

In this workshop we will go through the basics of working with Unity3D, discuss interesting projects made with the software and experiment with creating your own Augmented or Virtual Reality project. I will explain about the Vuforia library which can be used to create mobile AR apps and get you started to develop for Oculus Rift. For the workshop you will need Unity Pro which can be downloaded from unity3d.com. Please install the software beforehand. You can make use of the 30-day trial version.

On the 28th of August 2013 I defended my graduation project:

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.
