Effects of Visual Displays on 3D Iteraction in Virtual Environments
… some of the effects of virtual environment displays, specifically the head-mounted display (HMD) and the Cave Automatic Virtual Environment (CAVE), on 3D interaction tasks involving selection and manipulation. The motivation for this thesis comes from the lack of previous work that has …

Efficacy of retinal disparity depth cues in three-dimensional visual displays
… interest in three-dimensional (3-D) stereoscopic displays has prompted the need to assess the efficacy of retinal disparity depth cues. Accordingly, this study analyzed performance on two 3-D tasks under three levels of signal-to-clutter ratio as participants viewed three display formats portrayed …

An Evaluation of Visual Displays in Basal Readers and Social Studies Textbooks
… are few investigations on the more abstract data displays, or visual displays. This study presents a quantitative and a qualitative evaluation of visual displays in elementary basal readers and social studies textbooks. The four research questions were: (1) How do visual displays that are found in …

Training procedural tasks through the manipulation of multimedia in dynamic visual displays with computer-based technologies
… between the head-mounted displays the second research question could not be addressed since comparisons between these displays were not feasible. This inability to make comparisons between subtypes resulted in second phase of experiments concentrating on the fourth research …

Analysis of Performance Resulting from the Design of Selected Hand-Held Input Control Devices and Visual Displays
… design considerations for pointing devices and visual displays that will support wearable computer users. Twenty soldiers participated in an experiment using target acquisition software with five pointing devices and two visual displays. The findings of the research strongly support the use of a …

Infant attention to rate of infant directed speech in the context of varying levels of visual stimulation
… previous studies have paired the speech with a visual display, it was thought that perhaps the characteristics of the visual display affected infant preferences for rate of speaking. The present investigation was an attempt to explore this possibility. In Experiment 1, 3- to 4-month old infants …

The Impact of Instrumentation Location and Reliability on the Performance of Operators Using an Ecological Interface for Process Control
… (EID) is a recent philosophy for designing visual displays for human-machine interfaces that advocates displaying the higher-order relations and properties of a work domain so that adaptive operator problem solving is better supported for both normal and abnormal system conditions. Moreover, …

Detection of statistical differences between visual textures as a function of mean dot density
… of locally defined element density in visual textural stimuli was investigated. Ten female Ss participated in the experimental study for a total of two half-hour sessions each. The stimuli consisted of six replications of 40 visual displays. Four mean density (M.d.) conditions were …

The social organisation and behaviour of the striped field-mouse Rhabdomys Pumilio (Sparrman 1784) : studies in captivity and in the field
… was found to have a well-developed repertoire of visual displays, to use ultrasonic calls in social interactions, and to be dependent, to a certain extent, on chemical communication. In Part II, an attempt was made to confirm these findings in the field. Home ranges on the Cape Flats were …

Conjugate Reinforcement: The Effects of Stimulus Clarity
… Each component was associated with self-selected visual displays that diminished in clarity at different rates when responding fell below a pre-determined response rate. Response rates were analyzed from two aspects of the conjugate preparation, positive (or the "run up to stimulus clarity") and …

Anticipation of Movement Outcome Through Perception of Movement Kinematics
The influence of three types of visual displays and the relative importance of different body segments for the anticipation of movement outcome was investigated. Twelve novice and 13 expert tennis players participated in three experiments. In Experiment 1, the players observed the movements of an …
