Primary users can create a user experience (UX) for others—secondary users—when interacting with a system in public. Common ground occurs when people have certain knowledge in common and each knows that they have this shared understanding. This research investigates how designing for a secondary UX improves common ground during a patient-provider first encounter. During formative work, patients and providers participated in telephonic interviews and answered online questionnaires so that their respective information requirements for clinical encounters could be understood. The outcome of the formative work was a smartphone application prototype to be used as the treatment in an experimental study. In a mixed methods study, with a patient role-player using the prototype during a simulated clinical encounter with 12 providers, the impact of the prototype upon secondary user satisfaction and common ground was assessed. The main finding was that the prototype was capable of positively impacting secondary user satisfaction and facilitating common ground in certain instances. Combining the notions of human-computer interaction design, common ground, and smartphone technology improved the efficiency and effectiveness of providers during the simulated face-to-face first encounter with a patient. The investigation substantiated the notion that properly designed interactive systems have the potential to provide a satisfactory secondary UX and facilitate common ground.
