Opportunities and Limitations of Haptic Technologies for Non-visual Access to 2D and 3D Graphics
2014
Existing and emerging haptic technologies offer methods for non-visually rendering and interacting with 2D and 3D graphical information. These technologies include force feedback devices, touch surfaces with vibrotactile feedback, wearable vibrotactiles, and touch surfaces with electrostatic feedback. In this paper we will focus on approaches to non-visual access to 3D shapes. The interactive models focus on two approaches: simulation of 3D shape and perspective on a 2D touch surface; and interactive exploration of 3D shapes using physical motion in a virtual 3D space with either a force feedback controller or wearable haptics. The technologies will be reviewed along with suitability for th…
Community Resilience in Crises : Technology and Social Media Enablers
2014
Technology can contribute greatly to disaster resilience, especially by enhancing the interconnectedness between the authorities and the public and by facilitating the rapid exchange of information. This special issue of Human Technology: An Interdisciplinary Journal on Humans in ICT Environments is focused on technology and social media enablers of community resilience. Crises take on a variety of shapes and forms—natural or health disasters, terroristic and criminal acts, technology malfunctions, and large-scale accidents—at the local, regional, national, and global levels. Crisis management plans, created and implemented at the organizational level, typically involve public service and i…
Improving Participation, Accessibility and Compliance for Campus-Wide Mobile Emergency Alerting Systems
2009
University campus communities face a variety of hazards, from natural and technological disasters to terrorism and violence. In response to recent events, many campuses within the United States have begun to implement emergency notification systems utilizing email, text, and telephone-based messaging. These alerts are designed to reach members of the campus community, including faculty, staff, and students and most rely upon an opt-in model for participation. The present design of both the registration process and the notification messages raise several concerns as to the effectiveness of notification systems. This research presents findings from an examination of emergency notification sys…
