We report on the use case of an instrumented self-service lunch line of a research restaurant that gathers data about dining and diners, using scales, screens, and other collection instruments. The data collection is automated, but requires some participation or compliance from the diners. We developed and tested a non-intrusive LED cue system to guide diner behavior, evaluating its effectiveness through telemetry data, user observations and focus groups. Contrary to expectations, the system did not increase user compliance. To better understand user behavior, we applied context analysis, cognitive load, and affordance theories. The reflections of this research delivers a toolkit to support researchers in the human-computer interaction (HCI) field to analyze the factors for success/failure of guidance systems and/or guide the design of new such systems with high probability of success.
