Prototyping Lead | Fall 2019

About the Design

Inclusive self-checkout experience to reduce physical and mental toll on elderly users

Physically separated bagging area from checkout to space out distinct tasks and reduce stress

Added seating options at bagging to allow physical rest points

Need Identification

Completed ethnography and stakeholder interviews at local grocery store

Reaction time for arm movements increases with decreased knowledge of impending movements (Schneider and Sprague, 1995)

Increase in operational errors with pressure of others queuing behind elderly users (Asma)

60% of senior citizens indicate that lack of seating deters shopping (Center for Future Studies)


Developed low fidelity prototype to represent basic functionality

Conducted preliminary testing to identify necessary number of bagging aisles per checkout

Conducted user testing to validate lower stress versus standard self-checkout experiences
