To access interactive systems, blind and visually impaired users can leverage their auditory senses by using non-speech sounds. The current structure of non-speech sounds, however, is geared toward conveying user interface operations (e.g., opening a file) rather than large theme-based information (e.g., a history passage) and, thus, is ill-suited…

Research studies repeatedly emphasize the importance of vocabulary capabilities to a large variety of academic activities. This study compared a learning strategy that exclusively involved the visual review of vocabulary word-definition pairs to a strategy that, in addition, prompted participants to attempt free-recall retrieval of words to match…

Information Gathering is a knowledge construction process. Web learners make a plan for their Information Gathering task based on their prior knowledge. The plan is evolved with new information encountered and their mental model is constructed through continuously assimilating and accommodating new information gathered from different Web pages. In…

Introduction: The goal of this study is to expand our understanding of the relationships between selected tasks, cognitive abilities and search result interfaces. The underlying objective is to understand how to select search results presentation for tasks and user contexts Method: Twenty three participants conducted four search tasks of two types…

This experimental investigation replicates previous investigations of the effects of left margin screen background color hue to signal lesson sections on declarative knowledge and extends those investigations by adding a measure of structural knowledge. Participants (N = 80) were randomly assigned to receive 1 of 4 computer-based lesson treatments…

States that key aspects of "memoria," the ancient Art of Memory, especially its focus on vivid representational images set against distinct backgrounds, can be helpful in creating memorable, universal, and easily retrievable computer icons. (PA)

Argues that knowledge of cognition, memory, and graphic design can improve design outcomes for computer interfaces. Discusses cognitive processing for memory, terminology, proximity and shape, Gestalt principles in design, and usability. Lists recommendations for bringing a cognitive perspective to HTML projects and selected Web resources on…

Cognitive Structures and Linguistic Sequential Memory or Memory of Serial Order are not very well developed among illiterate people contrary to educated people. It affects the comprehension of abstract ideas and the usability of the system. Therefore the cognitive limitations of illiterate must be considered for instructional design and user…

This book examines human-computer interaction (HCI), with a focus on designing computer technology to be more usable by people. The book provides a multi-disciplinary approach to the subject through a synthesis of computer science, cognitive science, psychology, and sociology, and stresses a principled approach to interactive systems design that…
