Improvement in instructional practices through dynamic means of delivery remains a central consideration to technology educators. To help accomplish this, one must constantly utilize contemporary and cutting-edge technological applications in attempts to provide a more beneficial learning experience for students. These technologies must…

Customer needs for high-quality goods and the risk of product-liability litigation against businesses have made companies look for a way to sustain quality assurance in their products and services. Lean manufacturing is the latest and most successful system being used by companies to turn their business around. Visual inspection plays an important…

An object that moves is spotted almost effortlessly; it "pops out." When the observer is stationary, a moving object is uniquely identified by retinal motion. This is not so when the observer is also moving; as the eye travels through space all scene objects change position relative to the eye producing a complicated field of retinal motion.…

During locomotion, retinal flow, gaze angle, and vestibular information can contribute to one's perception of self-motion. Their respective roles were investigated during active steering: Retinal flow and gaze angle were biased by altering the visual information during computer-simulated locomotion, and vestibular information was controlled…

Attention and working memory limitations set strict limits on visual representations, yet researchers have little appreciation of how these limits constrain the acquisition of information in ongoing visually guided behavior. Subjects performed a brick sorting task in a virtual environment. A change was made to 1 of the features of the brick being…

Explains the hierarchic structure of the mammalian visual system. Proposes a model in which feedback pathways serve to modify sensory stimuli in ways that enhance and complete sensory input patterns. Investigates the functioning of the system through computer simulations. (ML)

Reviews literature in the field of human-computer interaction (HCI) as it applies to educational environments. Topics include the origin of HCI; human factors; usability; computer interface design; goals, operations, methods, and selection (GOMS) models; command language versus direct manipulation; hypertext; visual perception; interface…

Virtual Reality (VR) is a new medium which allows total stimulation of one's senses through human/computer interfaces. VR has applications in training simulators, nano-science, medicine, entertainment, electronic technology, and manufacturing. This paper focuses on some current and potential problems of virtual reality and virtual environments…

Shows that graphs can reveal much about feedback systems that formula conceal, especially as microcomputers can provide complex graphs presented as animations and allow students to interact easily with them. Describes feedback systems, evolution of the system, and phase diagram. (YP)

Growing interest in adult literacy has encouraged research and innovative programming in the field. This paper examines several pieces of software created by the Institute for the Study of Adult Literacy at Pennsylvania State University and explains their underlying conceptual foundations and the integration of visual materials. The Penn State…
