The Mwangaza Project: A Comprehensive Report on the Nationwide Baseline Survey of Technology Skills for Learners with Vision Impairment in Kenya

(Georgia Institute of Technology, 2016-12) Walker, Bruce N. ; Mbari-Kirika, Irene ; Miheso-O’Connor, Marguerite ; Georgia Institute of Technology. School of Psychology

This document presents the results of a major portion of the PEER-funded collaborative research project called the Mwangaza Project. The project is a shared effort between: the Sonification Lab at the Georgia Institute of Technology (“Georgia Tech”) in Atlanta, USA; inABLE, a non-profit organization based in Nairobi, Kenya, and Washington DC, USA; and Kenyatta University, in Nairobi. This research team has completed a two-phase project including (1) a nation-wide survey of the interests, needs, skills, and opinions of blind students and their teachers, with respect to information and communications technology (ICT, aka “technology”); and (2) initial development, deployment, and evaluation of some novel assistive technologies that represent potential new approaches to STEM education for students with vision loss. This report describes the baseline survey of students and teachers.
Map-based Priors for Localization

(Georgia Institute of Technology, 2004-09) Oh, Sang Min ; Tariq, Sarah ; Walker, Bruce N. ; Dellaert, Frank ; Georgia Institute of Technology. Center for Robotics and Intelligent Machines ; Georgia Institute of Technology. College of Computing

Localization from sensor measurements is a fundamental task for navigation. Particle filters are among the most promising candidates to provide a robust and realtime solution to the localization problem. They instantiate the localization problem as a Bayesian filtering problem and approximate the posterior density over location by a weighted sample set. In this paper, we introduce map-based priors for localization, using the semantic information available in maps to bias the motion model toward areas of higher probability. We show that such priors, under a particular assumption , can easily be incorporated in the particle filter by means of a pseudo likelihood. The resulting filter is more reliable and more accurate. We show experimental results on a GPS-based outdoor people tracker that illustrate the approach and highlight its potential.
Georgia Tech Psychology STING Telemetry Data Module For MiniSim

(Georgia Institute of Technology, 2015-08-27) Gable, Thomas M. ; Walker, Bruce N. ; Rajendra, Bhargav ; Georgia Institute of Technology. School of Psychology

As in-vehicle technologies become more integrated into the vehicle, researchers must have real-time vehicle data available to them to investigate new technologies. In driving simulation settings, it can often be difficult to get this information. In an effort to gather real-time data from the National Advanced Driving Simulator MiniSim we have developed the Simulator Telemetry INteGration (STING) module to pull any data the MiniSim would normally output to its data acquisition files, and make those data available for use within other programs. The module is fairly simple to integrate into a MiniSim as it is purely software based. This document was written as a guide for those who are interested in using the STING software, to inform them of what STING can do, inform users of how the system works, and then linking them to the software download. Please refer to the included software license. If you use the system for studies please simply cite this tech report.
The Use of Different Technologies During a Medical Interview: Effects on Perceived Quality of Care

(Georgia Institute of Technology, 2007-10) Caldwell, Britt ; DeBlasio, Julia M. ; Jacko, Julie A. ; Kintz, Erin ; Lyons, Kent ; Mauney, Lisa M. ; Starner, Thad ; Walker, Bruce N. ; Georgia Institute of Technology.

This two-phase study examines a physician’s use of one of five different types of technology to note a patient’s symptoms during the medical interview. In this between-subjects design, 342 undergraduates viewed one of several videos that demonstrated one condition of the doctor/patient interaction. After viewing the interaction, each participant completed a series of questionnaires that evaluated their general satisfaction with the quality of care demonstrated in the medical interview. A main effect of technology condition was present in both phases. Further, in Phase 2 we found that drawing the participant’s attention to the type of technology used has a divergent effect on their general satisfaction with the doctor/patient interaction depending on the technology condition. These findings have implications for healthcare providers such as how to address technology and which type of technology to use.
