Physical stores often layer promotions, signage, procedures, and tasks until both shoppers and employees operate in a state of quiet overload. BIEM turns overload signals into a measurable feature of the environment, highlighting where choice architectures, process steps, or concurrent demands exceed human bandwidth. By interpreting patterns in movement, hesitation, re-tracing, and task execution, BIEM links overload to specific locations, workflows, and communication touchpoints. Retailers gain a defensible basis for pruning complexity, restructuring tasks, and redesigning interfaces so that people can make faster, clearer decisions under real-world pressure.
