Closer Object Looks Smaller: Investigating the Duality of Size Perception in a Spherical Fish Tank VR Display

Fish Tank Virtual Reality (FTVR) displays provide compelling 3D experiences by rendering view-dependent imagery on a 2D screen. While users perceive a 3D object in space, they are actually looking at pixels on a 2D screen, thus, a perceptual duality exists between the object's pixels and the 3D percept potentially int…

Improving Early Navigation in Time-Lapse Video with Spread-Frame Loading

Time-lapse videos are often navigated by scrubbing with a slider. When networks are slow or images are large, however, even thumbnail versions load so slowly that scrubbing is limited to the start of the video. We developed a frame-loading technique called spread-loading that enables scrubbing regardless of delivery r…

FTVR in VR: Evaluation of 3D Perception With a Simulated Volumetric Fish-Tank Virtual Reality Display

Spherical fish tank virtual reality (FTVR) displays attempt to create a virtual "crystal ball" experience using head-tracked rendering. Almost all of these systems have omitted stereo cues, making them easy to build, but it is not clear how much this omission degrades the 3D experience. In this study, we evaluate perf…
