Multimodal interfaces offer great potential to humanize interactions with computers by employing a multitude of perceptual channels. This paper reports on a novel multimodal interface using auditory, haptic and visual feedback in a direct manipulation task to establish new recommendations for multimodal feedback, in particular uni-, bi- and trimodal(More)
OBJECTIVES The primary objective was to determine if wireless remote monitoring with automatic clinician alerts reduces the time from a clinical event to a clinical decision in response to arrhythmias, cardiovascular (CV) disease progression, and device issues compared to patients receiving standard in-office care. A secondary objective was to compare the(More)
With over thirty million individuals with disabilities being reported in the United States, and with information systems permeating nearly every aspect of society, there is a growing urgency to ensure that everyone has equal access to technology. To render information technologies universally accessible, researchers must have at their disposal an accurate(More)
The objective of this study was to derive empirical knowledge of the visual search strategies of computer users who suffer from age-related macular degeneration (AMD). This was accomplished by recording eye movement during the use of feature-enhanced software. The results from this study show that there are differences between users who have AMD and users(More)
Through an investigation of how the performance of people who have normal visual capabilities is affected by unimodal, bimodal, and trimodal feedback, this research establishes a foundation for presenting effective feedback to enhance the performance of individuals who have visual impairments. Interfaces that employ multiple feedback modalities, such as(More)
BACKGROUND Indications for implantable cardioverter defibrillators (ICDs) and cardiac resynchronization therapy defibrillators have greatly expanded in the last 5 years, encompassing a wider variety of patients with a multitude of comorbidities. To meet the needs of these patients, the managing clinicians need to streamline their follow-up care. New(More)
Multimodal interfaces have the potential to enhance a user's overall performance, especially when one perceptual channel, such as vision, is compromised. This research investigated how unimodal, bimodal, and trimodal feedback affected the performance of fully sighted users. Limited research exists that investigates how fully sighted users react to(More)
BACKGROUND Eye tracking is an accurate and objective means of measuring an instrument scan pattern. The purpose of this study was to determine if prior aircraft experience, phase of flight, and autopilot mode modified the instrument scan pattern of F-117A pilots. METHODS There were 23 F-117A pilots, grouped by prior aircraft experience, who flew an(More)
