“…Similarly to Free2C, Brar et al use image recognition to track users' heads to produce multiple steerable exit pupils for left and right eyes (Brar et al 2010a) (Brar et al 2010b). Here, they describe the design and construction of a stereoscopic display that doesnt require wearing special eye wear.…”

“…12 Project MUTED and HELIUM3D replace a conventional backlight with novel steering optics and a horizontally scanned light valve so that zones can be directed to appropriate viewers' eyes. 13 Liou et al use a synchro-signal LED scanning backlight to reduce crosstalk. 14 Stolle et al also introduce an electronically steerable backlight.…”

Dynamic mapping for multiview autostereoscopic displays

Multiview autostereoscopic displays have several image artifacts which prevent widespread adoption. Crosstalk between adjacent views is often severe, stereo inversion occurs at some head positions, and legacy 2-view content is difficult to display correctly. We introduce a method for driving multiview displays, dynamically assigning views to hardware display zones, based on potentially multiple observer's current head positions. Rather than using a static one-to-one mapping of views to zones, the mapping is updated in real time, with some views replicated on multiple zones, and some zones left blank. Quantitative and visual evaluation demonstrates that this method substantially reduces crosstalk.

“…However the desire to avoid worn hardware has motivated software solutions to viewer tracking, primarily through face detection [20]. A number of tracking displays such as those of the recent EU MUTED project [2], draw upon the Viola and Jones face detection algorithm [27]. The face is detected via a decision cascade of Haar wavelet basis functions that can rapidly reject poor candidate regions, and so is suitable for real-time tracking on resource constrained embedded hardware.…”

Three dimensional (3D) displays typically rely on stereo disparity, requiring specialized hardware to be worn or embedded in the display. We present a novel 3D graphics display system for volumetric scene visualization using only standard 2D display hardware and a pair of calibrated web cameras. Our computer vision-based system requires no worn or other special hardware. Rather than producing the depth illusion through disparity, we deliver a full volumetric 3D visualization -enabling users to interactively explore 3D scenes by varying their viewing position and angle according to the tracked 3D position of their face and eyes. We incorporate a novel wand-based calibration that allows the cameras to be placed at arbitrary positions and orientations relative to the display. The resulting system operates at real-time speeds (∼ 25 fps) with low latency (120 − 225 ms) delivering a compelling natural user interface and immersive experience for 3D viewing. In addition to objective evaluation of display stability and responsiveness, we report on user trials comparing users' timings on a spatial orientation task.
