Interaction design of community-driven environmental projects (CDEPs): A case study from the Anacostia Watershed.

Water is becoming an increasingly precious resource across the world, but citizens can help ensure good-quality water by helping to manage their local watersheds. Local, place-based advocacy projects that are strongly grounded within their geographical area have the potential to inspire environmental change as citizens come together to collectively address environmental challenges in their own neighborhoods. However, less attention has been given to these small, intensely place-based local projects. Our research focuses on the interaction design of technology to support small, local, place-based "community-driven environmental projects" (CDEPs) for water management in the Anacostia River Watershed. Analysis of case study data collected over a 3-y period to identify the needs of CDEP members provides the basis for the interaction design of technology known as NatureNet to support CDEPs. From this research, six design insights for supporting CDEPs are suggested: (i) a shared common endeavor connected to the identity of the members, (ii) ways for newcomers and experienced participants to share a common space and function together effectively, (iii) support for different sources of knowledge, (iv) different modes of participation and ways for participants to express themselves, (v) different ways to express status through diverse opportunities, and (vi) support for porous and changing leadership roles. Taken together, the findings from our study suggest a preference for technology-lite, highly flexible software that supports the diverse needs of CDEP members.

Usability and accessibility in consumer health informatics current trends and future challenges.

It is a truism that, for innovative eHealth systems to have true value and impact, they must first and foremost be usable and accessible by clinicians, consumers, and other stakeholders. In this paper, current trends and future challenges in the usability and accessibility of consumer health informatics will be described. Consumer expectations of their healthcare providers and healthcare records in this new era of consumer-directed care will be explored, and innovative visualizations, assistive technologies, and other ways that healthcare information is currently being provided and/or shared will be described. Challenges for ensuring the usability of current and future systems will also be discussed. An innovative model for conducting systematic, timely, user-centered research on consumer-facing websites at the National Cancer Institute (NCI) and the ongoing efforts at the National Institute of Standards and Technology (NIST) to promote health information technology (HIT) usability standards and evaluation criteria will also be presented.

Community response grids: using information technology to help communities respond to bioterror emergencies.

Access to accurate and trusted information is vital in preparing for, responding to, and recovering from an emergency. To facilitate response in large-scale emergency situations, Community Response Grids (CRGs) integrate Internet and mobile technologies to enable residents to report information, professional emergency responders to disseminate instructions, and residents to assist one another. CRGs use technology to help residents and professional emergency responders to work together in community response to emergencies, including bioterrorism events. In a time of increased danger from bioterrorist threats, the application of advanced information and communication technologies to community response is vital in confronting such threats. This article describes CRGs, their underlying concepts, development efforts, their relevance to biosecurity and bioterrorism, and future research issues in the use of technology to facilitate community response.

Usability of health Web sites for older adults: a preliminary study.

Although an increasing number of Web sites are devoted to providing health information to older adults, many sites have usability problems unique to this population. The purpose of this study was to explore the usability of three health-promoting Web sites specifically designed for use by older adults. This descriptive study used two usability assessment methods: (1) a heuristic evaluation by four experts in Web usability and gerontology and (2) a usability test by 10 senior Web users with a mean age of 73.9. The design aspects identified as inappropriate for seniors by experts were as follows: small font size, too much information on one page, and a failure to provide instructions. The older adults in this sample preferred a simple design with clear instructions. During testing, these individuals expressed great interest in online health information. However, they needed instructions on how to search for credible health information online. Some usability-testing methods might need to be modified for older adults' specific needs.
