Problem Statement

TSA officers use hardware and software that is not optimized for the change from 2D X-ray scanners to 3D CT scanners. This has led to errors in the screening process which can waste time, miss potential threats, and cause frustration. We set out to solve this problem by redesigning the GUI, developing user-focused training materials, and suggesting new hardware for manipulating the 3D images.

Process

Human Factors

• Focused on interface design, product development, and matching human psychology with computer input

  • Built and tested 3D manipulatives

  • Conducted usability testing across KPIs in learnability, memorability, efficiency, errors, and satisfaction

Cross Functional Teams

• Collaborated with cross-functional teams to develop a holistic and empirical understanding of our users

  • Worked with the data science team to analyze and predict user behavior based on a machine learning model

  • Used this behavioral analysis as input when reorganizing the GUI

Graphical User Interface

• Owned the end-to-end GUI design overhaul

  • Prototyped in Adobe XD

  • Worked within the confines of the defense industry

  • Tested with agents in the field and iterated
