“…Woodgate et al [38] and Dodgson [7] propose displays with three or four view-zones, each smaller than a fraction of the user's interpupillary distance (IPD). The positions of the user's eyes are detected and the contents (left eye or right eye views) are swapped to the appropriate view-zones for the user to perceive correct 3D imagery.…”

“…Most mobile 3D displays technologies are autostereoscopic (the user does not need any eyewear) and also are multiview displays (deliver several views to different view-zones). The most common approaches used to achieve these capabilities are parallax barriers [10], lenticular arrays [27] and directional backlighting [38].…”

We present Portallax, a clip-on technology to retrofit mobile devices with 3D display capabilities. Available technologies (e.g. Nintendo 3DS or LG Optimus) and clipon solutions (e.g. 3DeeSlide and Grilli3D) force users to have a fixed head and device positions. This is contradictory to the nature of a mobile scenario, and limits the usage of interaction techniques such as tilting the device to control a game. Portallax uses an actuated parallax barrier and face tracking to realign the barrier's position to the user's position. This allows us to provide stereo, motion parallax and perspective correction cues in 60 degrees in front of the device. Our optimized design of the barrier minimizes colour distortion, maximizes resolution and produces bigger view-zones, which support ~81% of adults' interpupillary distances and allow eye tracking implemented with the front camera. We present a reference implementation, evaluate its key features and provide example applications illustrating the potential of Portallax.

This chapter covers the state of the art in stereoscopic and autostereoscopic displays. The coverage is not exhaustive but is intended that in the relatively limited space available a reasonably comprehensive snapshot of the current state of the art can be provided. In order to give a background to this, a brief introduction to stereoscopic perception and a short history of stereoscopic displays is given. Holography is not covered in detail here as it is really a separate area of study and also is not likely to be the basis of a commercially viable display within the near future.Keywords Autostereoscopic display Á Binocular parallax Á Crosstalk Á Depth cue Á Disparity Á Geometrical distortion Á Glasses Á Head-tracked display Á Image artifact Á Integral imaging Á Light field display Á Monocular cue Á Multi-view display Stereoscopic display Á Stereoscopic perception Á Viewing zone Á Volumetric display Stereoscopic PerceptionThere are many factors involved in stereoscopic perception, and the relative importance of contributory perceptual factors in natural vision is not necessarily the same as for an artificial image. Consider a natural scene being observed; when one eye is covered the image appears to lose very little realism. However, images reproduced on a display appear to be considerably more realistic when stereo is applied to the image. This is particularly well demonstrated if an image is viewed

“…In the first 3D displays, manufactured by Sharp R&D, the userself calibrated their position to acquire the sweet spot via a 'viewer position indicator' (VPI) pattern [30] at the base of the display. More recently, viewer position is actively tracked (typically via the head) to direct the sweet spot toward the viewer by reconfiguring the LCD barrier in real-time [29].…”

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.
