Background: The effective 3D manipulation, comprehension, and control of 3D objects on computers are well-established lasting problems, which include a display aspect, a control aspect, and a spatial coupling between control input and visual output aspect, which is a debatable issue. Most existing control interfaces are located in front of the display. This requires users to imagine that manipu...

In this paper, we present a stereoscopic kiosk for virtual museum, which combines techniques of stereoscopic displays, image-based rendering, virtual reality, and augmented reality. In our kiosk system, artifacts are presented as object movies, and can be integrated with both image-based panoramas and geometry-based scenes for constructing virtual museum. Two display devices are used in the kio...

The limited screen space in small technical devices imposes considerable usability challenges. On the one hand objects displayed on small screens should be big enough to be hit successfully, but also small enough to house several objects on the screen at the same time. However, findings up to now show that single pointing is more effective in a large display compared to a smaller display. In th...

A technique that relies on integer wavelets to deliver energy to pixels and display gray shades in rms responding matrix displays is proposed. A large number of gray shades can be displayed without flicker using simple addressing waveforms with a few voltage levels.

Stereoscopic depth discrimination was investigated in crossed and uncrossed directions using stimuli defined by binocular disparity differences embedded in dynamic random-dot stereograms. Across three experiments, fixation was directed to a point on the display screen (which placed crossed stimuli in front of and uncrossed stimuli behind, the background dots of the stereogram), to a point in fr...
