Dr. Tobias Langlotz is a Senior Lecturer at the University of Otago. Tobias was previously a senior researcher at the Institute for Computer Graphics and Vision (Graz University of Technology, Austria) where he also obtained his PhD.

Tobias' main research interests are in Human-Computer Interaction and Ubiquitous Computing. Recently, he has been working on mobile telepresence solutions allowing people to share their environment with remote users relying only on mobile and wearable devices. Tobias is also working on novel head-mounted display technology for Augmented Reality and is currently investigating Computational Glasses using head-mounted displays for managing visual impairments. Most of his works are at the intersection of HCI, Computer Graphics, Computer Vision and Mobile Computing. Previous to his work on mobile devices, he worked in the field of Spatial Augmented Reality and Holographic displays. His research methodology is both bottom-up (build and evaluating technology and interfaces) and top-down (application-driven). Over the years, Tobias was involved in various academic and industrial projects while engaging as an active member within the international research community.

Tobias won an "Early Career Award for Distinction in Research" from the University of Otago in 2017 and was a finalist for the supervisor of the year award in 2016.

He is a member of IEEE, ACM and serves as a reviewer and auditor for leading conferences, journals and institutions.

Research Assistants

Jonny is currently pursuing a PhD, focusing on Embodied Learning using Virtual environments, and the impact a user's sense of presence has on one's ability to learn in such environments. As such he is becoming an expert in learning in Virtual Environments while already being an expert in Unity and all kinds of VR hardware. Previously, his Master's work focused on a systematic inquiry into the problems associated with Head-mounted Display technologies with respect to the application of Mixed Reality. During his Honors, he implemented and evaluated an Augmented Reality implementation of a physical rehabilitation test. His interests are in politics, education, and the general well-being and progression of all. He also enjoys mountain biking, various sports, and musical art.


Matt is a PhD student supervised by Tobias and Holger working on Mixed-Reality Telepresence issues. Matt speaks fluently several programming languages and fought several brave (and successful) wars with Android, Unreal, Unity 3D and building his own head-mounted display prototype. Matt already worked with us on radiometric compensation for head-mounted displays during his Honours degree was researching an approach connecting distant people and places during his Masters. Matt is increasingly interested in photography, but spends most of his time outside of the university working as a freelancer.


Chris is currently a PhD student focusing on stroke rehabilitation using mixed reality with head mounted displays. Previously, his Master's work focused on developing a new interface to physically explore medical volume data using a mobile tablet computer. During his Honors, he worked on predicting American Football games using different prediction models and comparing it against previous models from literature. His interests include sports (American football and soccer), movies, finance and traveling.



Jacob is a PhD student supervised by Tobias and Holger. His research focuses on immersion and the feeling of presence in mobile telecommunications through the development of an immersive videoconferencing application. He is a master in finding undocumented Android "features" and we are sure that he can guess Android phones by looking at their camera image buffers. His interests include Software Design, Networking and Physics, and in his spare time he likes to play guitar and video games.



Stu is a PhD student working on Voxel-based Mixed Realities supervised by Holger and Tobias. Before coming to Otago, Stu was working on industrial computer-vision problems but luckily the the good surf around Dunedin (and of course his research topic) brought him to pur group to pursue a PhD.



Lewis is a PhD student co-supervised by Tobias. He is working on exploring Augmented Reality to extend the experience of live sport events with his other supervisors are Stefanie Zollmann and Steven Mills from Computer Science. Lewis worked before on the Augmented Reality Sandbox as a studentship project and on powerline detection using smartphones for his Master thesis. Lewis also worked as a demonstrator/tutor. His main interests are computer graphics/vision, and virtual/augmented reality. His spare time interests include skiing, guitar, and making video games.



Jonathan is a research assistant working with us on Computational Glasses and their applications to colour vision deficiency. He was already involved in several projects with the HCI lab as part of his course work or as a research assistant including volume visualisation techniques using tablet devices or situated analytics. If you have a car problems talk to him ... if you like cars or videos with cars... talk to him.




Rosa is a visitor from the University of California in Santa Cruz. Rosa's background is in Cognitive Science but she is very passionate in Human-Computer Interaction and works with us on eye-tracking for Augmented Reality and Computational Glasses.




Oliver is a research assistant and summer intern working with us. After doing a special topic paper with us, Oliver started to work with us on investigating deep learning for computational glasses and voxel-based realities. Apart from working with us, thinking about his own companies, and securing the stadium, Oliver is also doing a double major in Information and Computer Science.




Alex received a summer research scholarship working with us on virtual hand illusions in Virtual Reality using Unity 3D, Leap Motion sensors, and Oculus Rift. Apart from this, Alex is working on her Information Science and Computer Science degree.





Noel is a research assistant and summer intern working with us on mixed voxel realities which includes streaming and visualising volumetric data captured by several Kinect depth cameras which is supervised by Holger and Tobias. Noel also helped us in joint project with our colleagues in Psychology. He is becoming an expert in voxel-based realities and we are sure his dreams are made of Voxels.
