VidSTR: Automatic Spatiotemporal Retargeting of Speech-Driven Video Compositions

Video editors often record multiple versions of a performance with minor differences. When they add graphics atop one video, they may wish to transfer those assets to another recording, but differences in performance, wordings, and timings can cause assets to no longer be aligned with the video content. Fixing this is…

A Scaffold-Based Tool for Product Design Variations in Virtual Reality

Product design is an iterative process involving several kinds of drawing techniques. Analytic drawing, which involves the use of guidelines or scaffolds to draw the object's shape curves, aids in achieving precision and accuracy. Freehand drawing allows designers to add details without guidance. The set of scaffold,…

ScaffoldSketch: Accurate Industrial Design Drawing in VR

We present an approach to in-air design drawing based on the two-stage approach common in 2D design drawing practice. The primary challenge to 3D drawing in air is the accuracy of users' strokes. Beautifying or auto-correcting an arbitrary drawing in 2D or 3D is challenging due to ambiguities stemming from many possib…

RealitySketch: Embedding Responsive Graphics and Visualizations in AR through Dynamic Sketching

We present RealitySketch, an augmented reality interface for sketching interactive graphics and visualizations. In recent years, an increasing number of AR sketching tools enable users to draw and embed sketches in the real world. However, with the current tools, sketched contents are inherently static, floating in mi…

TransceiVR: Bridging Asymmetrical Communication Between External and VR Users

Virtual Reality (VR) users often need to work with other users, who observe them outside of VR using an external display. Communication between them is difficult; the VR user cannot see the external user’s gestures, and the external user cannot see VR scene elements outside of the VR user’s view. We carried out format…

View-Dependent Effects for 360° Virtual Reality Video

“View-dependent effects” have parameters that change with the user’s view and are rendered dynamically at runtime. They can be used to simulate physical phenomena such as exposure adaptation, as well as for dramatic purposes such as vignettes. We present a technique for adding view-dependent effects to 360◦ video, by…

View-Dependent Video Textures for 360° Video

A major concern for filmmakers creating 360° video is ensuring that the viewer does not miss important narrative elements because they are looking in the wrong direction. This paper introduces gated clips which do not play past a gate time until a filmmaker-defined viewer gaze condition is met, such as looking at the…

TutoriVR: A Video-Based Tutorial System for Design Applications in Virtual Reality

Virtual Reality painting is a form of 3D-painting done in a Virtual Reality (VR) space. Being a relatively new kind of art form, there is a growing interest within the creative practices community to learn it. Currently, most users learn using community posted 2D-videos on the internet, which are a screencast recordin…

Depth Conflict Reduction for Stereo VR Video Interfaces

Applications for viewing and editing 360° video often render user interface (UI) elements on top of the video. For stereoscopic video, in which the perceived depth varies over the image, the perceived depth of the video can conflict with that of the UI elements, creating discomfort and making it hard to shift focus. T…

Immersive Trip Reports

Since the advent of consumer photography, tourists and hikers have made photo records of their trips to share later. Aside from being kept as memories, photo presentations such as slideshows are also shown to others who have not visited the location to try to convey the experience.However, a slideshow alone is limited…
