95	95	In our situation, we recruit 20 students in our class to simulate the research. Since they are not real PwD, we ask them to act as if they were in home settings and we observe their behavior and expression. These data will also be reviewed after the evaluation to obtain the data and feedback.

97	97	In order to collect qualitative data, we have prepared two questionnaires to give to the participants: the affect assessment questionnaire and the system assessment questionnaire.

99		-* affect assessment
100		-the affect assessment questionnaire has the purpose of tracking changes in the participant's affect state before and after interacting with Pepper. The questionnaire consists of a list of 10 statements each representing one emotion and participants will be asked to give a score of 1 through 5 to each statement depending on the intensity of the emotion as experienced during the questionnaire. The affect questionnaire will be given twice, once before the interaction with Pepper and once after.

102		-* system assessment
103		-for assessing the quality of Pepper's interaction we used the Subjective Assessment of Speech System Interfaces (SASSI) questionnaire. The SASSI questionnaire is wildly used in research to evaluate speech and conversational systems. The questionnaire contains 36 questions divided into six main factors: System Response Accuracy, Likeability, Cognitive Demand, Annoyance, Habitability, and Speed. The questions are short and unambiguous and the length of the questionnaires is not too long which could cause the participants to give fast and unreliable answers but it is also long enough so that a good amount of information is collected.
	103	+The affect assessment questionnaire asks the participant to describe his/her mood and feelings experienced during a task. The questionnaire is given two times: once before the experiments and once after. When compiling the questionnaire before the experiment the task that is taken as a reference is chosen by the participant based on his/her most common daily, challenging tasks. When doing the questionnaire after the interaction with Pepper the questions reference the task that has just been completed with Pepper. The purpose of this questionnaire is to compare the feelings experienced by the participant during a typical task with the feelings experienced during the task with Pepper. The questionnaire has 6 questions in total and they are s designed to answer research questions as listed below:

107	107	For this study, we simulate the real research by including 20 students in our class. To avoid too much gender imbalance, there will be at least five men and five women. All participants will be asked to pretend to be a demented person and to make the simulation as real as possible.
