People are recruited to participate in the test based on rigorous selection and screening criteria. They are invited to a central location, usually a Tangible facility, or are visited in their own home. Using their own device (phone, tablet or laptop – whatever they use for the subject in question) they are invited to conduct a series of exercises and missions whilst being observed and recorded by our researcher. Stimulus can be created and served to the respondent in a more natural and realistic way than pulling a concept board from a bag. Following the exercise, a short interview focuses on any observed issues and also delves deeper into understanding what has been noticed, emotional responses, and potential areas for improvement.
