Usability Test and Workload Analysis

Project Objectives

  • Test the effectiveness of Collision Avoidance Technology (CAT) with respect to driver behavior and performance.
  • Conduct the sensitivity analysis of the CAT devices
  • Offer design solution for a CAT system based on driver’s perspective
  • Estimate potential benefits of implementing a CAT system for public transportation

Important Results

  • The overall effectiveness of a CAT system was about 75%, and the acceptance was about 69%.
  • Drivers’ reliability was subjected to change over a period of time.
  • Drivers adjusted their reliability of a CAT system based on the level of the false warning rate.
  • After drivers continuously experienced a high false warning rate, they considered warnings as a nuisance.

Improve Student Learning in Augmented Reality Environments

Project Objective

  • To explore how metacognitive monitoring feedback influences student performance in an augmented reality (AR) environment

Important Results

  • Metacognitive monitoring feedback improves student learning performance in augmented reality environments.
  • Metacognitive monitoring feedback helps learners have better calibration and more accurate responses in augmented reality environments.
  • Metacognitive monitoring feedback influences students reviewing feedback time in augmented reality environments
