We describe the design, implementation, calibration and detailed visual error analysis of a 3D perspective-corrected spherical display that uses multiple projectors. The display system is calibrated via 3D reconstruction using a single inexpensive camera. We perform an error analysis of the system in terms of all error sources (calibration/tracking), and our results provide practical guidelines for building a spherical FTVR display that can be applied to other geometric displays.

We'll be presenting this at ACCV in Taipei in November.
2016/03/21 - Video Highlighting at GI 2016
Video is used extensively as an instructional aid within educational contexts such as blended (flipped) courses, self-learning with MOOCs and informal learning through online tutorials. We provided students with a number of video interface features to establish which they would find most useful for video courses. We designed an interface which uses textbook-style highlighting on a video filmstrip and transcript, which students found to be generally helpful for navigating educational video.

We'll be presenting this at Graphics Interface in Victoria in early June.
2014/12/08 - Spheree at VR 2014
We present Portable-Spheree, an interactive spherical rear-projected 3D-content-display that provides perspective-corrected views according to the user's head position, to provide parallax, shading and occlusion depth cues. Portable-Spheree is an evolution of the Spheree and it is developed in a smaller form factor, using more projectors and a dark-translucent screen with increased contrast. We present some preliminary results of this new configuration as well as applications with spatial interaction that might benefit from this new form factor.

We'll be presenting this at IEEE VR in Provence in March.
