Multimodal markers for technology-independent integration of augmented reality devices and surgical navigation systems

Augmented reality (AR) permits the visualization of pre-operative data in the surgical field of view of the surgeon. This requires the alignment of the AR device’s coordinate system with the used navigation/tracking system. We propose a multimodal marker approach to align an AR device with a tracking system: in our implementation, an...

HoloLearn: Using holograms to support naturalistic interaction in virtual classrooms

Traditional online communications tools used in education are limited in terms of fostering naturalistic or life-like interaction. Such limited interactions in classrooms can negatively impact learning. Holograms are promising tools that show potential to overcome such limitations by affording more life-like interactions in virtual classrooms...

Perspectives of patients and professionals on information and education after myocardial infarction with insight for mixed reality implementation: Cross-sectional interview study

Background: Patient education is crucial in the secondary prevention of cardiovascular disease. Novel technologies such as augmented reality or mixed reality expand the possibilities for providing visual support in this process. Mixed reality creates interactive digital three-dimensional (3D) projections overlaying virtual objects on the real...

Comparing Human Factors for Augmented Reality Supported Single-User and Collaborative Repair Operations of Industrial Robots

In order to support the decision-making process of industry on how to implement Augmented Reality (AR) in production, this article wants to provide guidance through a set of comparative user studies. The results are obtained from the feedback of 160 participants who performed the same repair task on a switch cabinet of an industrial robot....
