The ALIGN (Application for Locational Intelligence and Geospatial Navigation (ALIGN) ATL app is a user-friendly, mobile device app for pedestrian route planning and navigation in Atlanta, Georgia. The app is designed with special features that aid older adults and people with mobility and/or visual limitations in avoiding outdoor environmental barriers, such as uneven sidewalks and missing curb cuts, by intelligently identifying routes that are tailored to the individual’s specific needs and abilities. Pick your starting point, destination, and most important parameters, and ALIGN will create a route that best suits the options you’ve selected. Parameters include audible crossing signals, street lights, low crime rates, sidewalks, and more. The app will notify you of conflicts both before you start your route and during the turn-by-turn navigation. ALIGN ATL available on the Apple App Store

Autobed – Web controlled electric hospital bed

PI Charlie Kemp

The Autobed module is an additional module for an Invacare fully electric hospital bed (Model 5410IVC) so that the bed can be controlled from a web-based interface. This module can be easily plugged between the hand control and the Invacare bed, without having to modify any existing hardware on the bed. The Autobed technology gives the control of an electric bed to the motor impaired bedridden person. This enables any motor impaired person who can operate a web browser to control their own electric bed at a very low cost. Invacare, Co. is currently working on commercializing Autobed.

Brain Food

PI Maribeth Gandy-Coleman

This is the code-base for the Brain Food prototype tablet-based cognitive intervention game. It is written in using the Unity3D game engine. It provides an example to the game developer community of how variable priority training (VPT) can be integrated into a “time management” style game.

Food for Thought Platform

PI Maribeth Gandy-Coleman

This is a platform for creating custom accessible instrumented “time management” games for serious games research/scientific experiments by non-technologists. It includes in-editor “wizards” that allow the user to create levels of a cognitive game within difficulty and multi-tasking requirements they define. It has a built-in logging system to collect detailed play data. It comes with hundreds of sample levels built by psychology researchers studying cognitive training. It is built around game themes, mechanics, and interfaces that were tuned for older adult players. This platform has been used in at least a dozen cognitive game and assessment studies over the period of six years

GaitRate iOS App 

Co-PIs Brian Jones & Ted Johnson

The GaitRate App is a handheld replacement for the traditional stopwatch method of gait speed measurement typically used in home visit assessments and research studies. The app returns a calculated gait speed measurement and survival estimates for older patients (65-95), based on published research. The iOS GaitRate App is now available on the Apple AppStore for use by healthcare providers: For more Information on the GaitRate iOS App:  

The GaitRate Wall-Mount System 

Co-PIs Brian Jones & Ted Johnson

The GaitRate Wall-Mount System (Patent: US11624755B2) was developed as a simple solution for clinical staff to measure short-distance gait speed, which can be used as a proxy for physical function and often serves as an indicator of fall risk and health related decline. The solution consists of a bi-directional system with a screen and control button on either end of a 6-meter course. Two sensor boxes are located on either end of the 4-meter timed zone to provide the speed measurement. The user instructs the subject to walk to the other control button at their normal walking speed, then presses the control button on one end and tells them to go. Sensors activate on the button press and trigger as the subject walks past. The system then ends the measurement and returns the results on both screens, allowing the user to write down the speed result in meters per second. For more information:  

Unity Vision Loss Tools 

PI Maribeth Gandy-Coleman

This is a drag-and-drop plugin for the Unity3D game engine that allows game developers to explore how their interface would appear to people with eight types of vision impairment.
