68499 news 1308846287 1475896177 CATEA (Georgia Tech's Center for Assistive Technology and Environmental Access), through its lab, the Work RERC, and the engineering team at Assistive Technology Partners, University of Colorado, Anschutz Medical Campus, has been exploring the use of task-prompting systems that could aid an individual with a disability to successfully perform assembly line work. A linear and a non-linear prompting system are being compared to determine if one is more effective than the other. In both systems, there is a sequence of tasks that need to be performed. In the linear prompting system, the individual must determine if the task has been performed and then hit a button to check it off the list and proceed to the next task. In the non-linear system, we have developed a tool that automatically determines if the task has been performed. The tool uses environmental sensors to know what steps have been completed. If the task has been completed, the next step is automatically presented. In addition to task advancement, the automated prompting systems can recognize basic error scenarios. The job that was chosen to test the prompting system involves packaging novelty Chocolate First Aid Kits. Our hypothesis is that the non-linear system will enable persons with cognitive disabilities to perform more effectively (fewer errors) and more efficiently (decreased time to complete a task).
