When evaluating the surface appearance of real objects, observers engage in complex behaviors involving active manipulation and dynamic viewpoint changes that allow them to observe the changing patterns of surface reflections. We are developing a class of tangible display systems to provide these natural modes of interaction in computer-based studies of material perception. A first-generation t...

StereoGraphics Corporation has introduced a new flat-panel autostereoscopic display, the SynthaGram. It produces bright, clear, and satisfying three-dimensional images that may be viewed from a substantial angle of view by many observers. A progression of perspective views, like that used by the parallax panoramagram, is created either by computer or photographic means. Each view is sampled at ...

Using a novel enumeration task, we examined the encoding of spatial information during subitizing. Observers were shown masked presentations of randomly-placed discs on a screen and were required to mark the perceived locations of these discs on a subsequent blank screen. This provided a measure of recall for object locations and an indirect measure of display numerosity. Observers were tested ...

This paper describes 4-views display system that can be viewed from any direction (i.e., the display has four viewing zones so as to perceive a screen view of the display at all directions around a table). The authors have ever researched information display systems involving 3D imaging. However, a conventional monitor display is viewed from one direction, that is, the display has narrow viewin...

We present a spatial audio display technique that overcomes the presentation rate bottleneck of traditional monaural audio displays. Our compact speech display works by encoding message semantics into the acoustic spatialisation. In user testing, this display facilitated better recall of events than a conventional small screen visual display. Moreover, results showed that this mapping aided in ...

Method for image portion retrieval and display for the relatively large scale of imagery data onto comparatively small size of display is proposed. The method is suitable to the data compression methods based on block coding. Through experiments with satellite imagery data, it is found that the proposed method is useful for the display onto small sized screen such as mobile phone display and so...
