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)
Prototyping
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
