“…A pseudo 3D display was created with one of the projectors operating in the classic (2D) display mode. See Jorke et al [40] for more details about display modes. Because the participant's motor activity (namely the types of actions used for navigating the terrain) in interactive Experiment 2 was measured, we avoided using the typical control devices such as computer mouse which could enhance a stereotypical behaviour in participants.…”

This study explores the influence of stereoscopic (real) 3D and monoscopic (pseudo) 3D visualization on the human ability to reckon altitude information in noninteractive and interactive 3D geovisualizations. A two phased experiment was carried out to compare the performance of two groups of participants, one of them using the real 3D and the other one pseudo 3D visualization of geographical data. A homogeneous group of 61 psychology students, inexperienced in processing of geographical data, were tested with respect to their efficiency at identifying altitudes of the displayed landscape. The first phase of the experiment was designed as non-interactive, where static 3D visual displays were presented; the second phase was designed as interactive and the participants were allowed to explore the scene by adjusting the position of the virtual camera. The investigated variables included accuracy at altitude identification, time demands and the amount of the participant's motor activity performed during interaction with geovisualization. The interface was created using a Motion Capture system, Wii Remote Controller, widescreen projection and the passive Dolby 3D technology (for real 3D vision). The real 3D visual display was shown to significantly increase the accuracy of the landscape altitude identification in non-interactive tasks. As expected, in the interactive phase there were differences in accuracy flattened out between groups due to the possibility of interaction, with no other statistically significant differences in completion times or motor activity. The increased number of omitted objects in real 3D condition was further subjected to an exploratory analysis.

“…The existing technique employed by Dolby [21] uses two interference filters that transmit different spectral bands per each color primary (Fig. 10, left) [6]. These filters are applied to the viewer's glasses so that the transmission bands for the two eyes are mutually exclusive.…”

“…Another instantiation of temporal interlacing uses a time-varying color filter at the display to deliver the left-and right-eye images over time. The viewer wears passive glasses that transmit the appropriate wavelengths for the left and right eyes [5,6]. Yet another instantiation uses active glasses that alternate between transmitting and blocking the images delivered to an eye [1,5].…”

Stereoscopic 3D display with color interlacing improves perceived depth

Temporal interlacing is a method for presenting stereoscopic 3D content whereby the two eyes' views are presented at different times and optical filtering selectively delivers the appropriate view to each eye. This approach is prone to distortions in perceived depth because the visual system can interpret the temporal delay between binocular views as spatial disparity. We propose a novel color-interlacing display protocol that reverses the order of binocular presentation for the green primary but maintains the order for the red and blue primaries: During the first subframe, the left eye sees the green component of the left-eye view and the right eye sees the red and blue components of the right-eye view, and vice versa during the second sub-frame. The proposed method distributes the luminance of each eye's view more evenly over time. Because disparity estimation is based primarily on luminance information, a more even distribution of luminance over time should reduce depth distortion. We conducted a psychophysical experiment to test these expectations and indeed found that less depth distortion occurs with color interlacing than temporal interlacing.

Science Arts & Métiers (SAM)is an open access repository that collects the work of Arts et Métiers ParisTech researchers and makes it freely available over the web where possible. ABSTRACTSelection of moving targets is a common, yet complex task in human-computer interaction (HCI) and virtual reality (VR). Predicting user intention may be beneficial to address the challenges inherent in interaction techniques for moving-target selection. This article extends previous models by integrating relative head-target and hand-target features to predict intended moving targets. The features are calculated in a time window ending at roughly two-thirds of the total target selection time and evaluated using decision trees. With two targets, this model is able to predict user choice with up to ∼ 72% accuracy on general moving-target selection tasks and up to ∼ 78% by also including task-related target properties.
