Background and interests

Dr Tobias Langlotz is a Full Professor at the University of Otago and co-leads the HCI group. Tobias' primary research interests are in Human-Computer Interaction, Wearable and Ubiquitous Computing, often evolving around using Augmented Reality and other techniques from Visual Computing. At the moment, Tobias is interested mainly in Computational Glasses and Vision Augmentations and their potential for compensating vision impairments or enhancing human perception. He is also working on nomadic, highly mobile and wearable telepresence solutions that allow people to share their environment with remote users. Here, he is particularly interested in new forms of tourism using virtual and augmented reality technologies.

Finally, Tobias is interested in challenges and technologies for continuous use of Augmented Reality technology (Pervasive Augmented Reality).

Previous to his current research work, he worked in the field of Mobile and Handheld Augmented Reality, Spatial Augmented Reality and Holographic displays. His research methodology is both bottom-up (build and evaluating technology and interfaces) and top-down (application-driven). Tobias is an active member of the international research community and, among other service roles, served as General chair for IEEEVR 2022 (Christchurch/Online) and IEEEVR 2023 (Shanghai).

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. Tobias is currently the Science Leader of an MBIE Endeavour Research program, but his research is also supported by two Marsden grants, a National Science Challenge SfTI seed grant, a Royal Society Catalyst seed grant, and he is a collaborator on an MBIE smart ideas grant. His work has further been supported by Snap Inc., Qualcomm, Lumus, Internet NZ, and Nokia.

He is deputy director of the ARIVE network (Australasian Researchers in Interactive Virtual Environments), is a member of IEEE , and ACM , and serves as a reviewer and auditor for the leading venues in HCI / AR / VR .
