1. Account for prior mobile experience, but do not assume too much. Most study recruits will have experience with at least one mobile device. However, do not assume that people know the device make or model, industry lingo (e.g., “converged device”), or acronyms (e.g., “SMS”). Mobile-device interfaces vary greatly. Participants’ performance may suffer if a study requires a device that differs from the ones they own. Conversely, a participant may perform inordinately well if using a familiar device. Design both the recruiting screener and the study accordingly.
