The participants were shown the interface which visualised a daily review of activities of a previous user called John. Participants were then given a short questionnaire which could only be answered reviewing the interface. The questions were of the type “What was John doing when the robot reminded him to drink” or “What was John eating when the robot asked if he needed any assistance?” or “What colour is the cup John drinks with?”. The experimental session for each participant included an introduction, completion of consent and demographics questionnaires, the actual study with participants using the interface and final questionnaires. The sessions lasted about one hour per participant, including 15-30 minutes on the actual interaction.
