ItemUtility of a Mobile Route Planning App for People Aging with Disability(IARIA, 2018) Sanford, Jon ; Melgen, Sarah ; Guhathakurta, Subhrajit ; Zhang, Ge ; Georgia Institute of Technology. Center for Assistive Technology and Environmental Access (CATEA) ; Georgia Institute of Technology. Center for Graphic Information SystemsMobility is a key contributor to an individual’s community living and participation. As a result, outdoor environmental barriers, such as uneven sidewalks and no curb cuts, play a crucial role in the development of disability and loss of independence among individuals aging with mobility and vision limitations. To compensate, people with disabilities typically plan routes before going out. However, they often lack the appropriate street-level information about the environment to plan routes that meet their abilities and needs for safety and accessibility (e.g., the location of curb cuts and crosswalks). As a result, the real impediment to outdoor mobility is not the actual barriers, but the lack of information about those barriers for route planning. To provide the street-level information about barriers that would maximize the independent living and community participation of people with mobility disabilities, the project team developed a working prototype of the Application for Locational Intelligence and Geospatial Navigation (ALIGN) based on static graphical information systems (GIS) data (e.g., physical infrastructure, slope, crime rates and land uses). This study details the utility testing of the application with individuals aging with mobility and vision limitations by using direct observation, think-aloud and open-ended questionnaires. Findings indicate that participants found the application to be potentially useful, especially in unfamiliar locations. However, testing also indicated a number of refinements, including multimodal input and outputs that would enhance the utility of the initial prototype. Additional design criteria will inform the next prototype, including use of consistent audio/visual feedback, and simpler directions. These criteria will be applied to create a more usable application for the target population.

ItemConfronting An Uncertain Future: Planning in the Era of Climate Change and Other Global Crises(Georgia Institute of Technology, 2012-08-30) Guhathakurta, Subhrajit ; Georgia Institute of Technology. College of Architecture ; Georgia Institute of Technology. Center for Geographic Information Systems ; Georgia Institute of Technology. School of City and Regional PlanningWe are living in an age of uncertainty that is unique at several levels. The current economic downturn precipitated by the U.S. subprime mortgage debacle, the potential for catastrophic climate change, the two wars in Iraq and Afghanistan, and more generally the war on terror, profoundly affects our ability to plan for a secure future. These unfolding events point to an immensely complex world with multiple layers of uncertain drivers and unknown "tipping points" and “Black Swans”. Now, more than ever, the most significant issues impacting cities and regions are forces outside their borders. This presentation is about confronting these challenges and finding a pathway to articulate the uncertainties through a different form of planning. Along the way I will discuss the evolving concept of sustainability and an approach to planning with hierarchical scenarios. I will also illustrate our efforts to develop some novel modeling and visualization tools to monitor and communicate sustainability indicators.
