We introduce Camera Time Warp (CamWarp), a novel reprojection technique for video-see-through augmented reality, which reduces the registration error between captured real-world videos and rendered virtual images. Instead of rendering the image plane

Telepresence systems have the potential to overcome limits and distance constraints of the real-world by enabling people to remotely visit and interact with each other. However, current telepresence systems usually lack natural ways of supporting int

Interaction tasks in virtual reality (VR) such as three-dimensional (3D) selection or manipulation of objects often suffer from reduced performance due to missing or different feedback provided by VR systems than during corresponding realworld intera

We evaluate two methods of signalling abrupt direction changes of a robotic platform using a Mixed Reality avatar. The "Body" method uses gaze, gesture and torso direction to point to upcoming waypoints. The "Path" method visualises the change in dir

Stylo-Handifact is a novel spatial user interface consisting of a haptic device (i. e., Stylo) attached to the forearm and a visualization of a virtual hand (i. e., Handifact), which in combination provide visuo-haptic feedback for posture training a

We evaluate the ability of locally present participants to localize an avatar head’s gaze direction rapidly in hosted telepresence. We performed a controlled user study to test two potential solutions to indicate a remote user’s gaze. We analyze

We propose a metric for quick short-term comfort and discomfort evaluation of non-resting hand postures. The metric is further improved using data from user studies. Comparing subjective user ratings with the metric indicates the metric to be a fitti

Manipulation of 3D objects is important for collaboration and education, where a presenter might wish to manipulate a 3D object to present it to an audience. We present Mesh-Grab and Arcball-3D; two ray-based techniques for manipulating remote 3D obj
