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.

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.
	99	+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. All questionnaire questions are expressed in the form of statements and the participant can express one out of 6 levels of agreement/disagreement from strongly disagree to strongly agree with the only exception being the additional remarks field at the end of the system assessment questionnaire.

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 right after. The purpose of this questionnaire is to compare the feelings experienced by the participant before the interaction with Pepper and after to study how Pepper influences the participant's feelings. The questionnaire has 6 questions each designed to measure the level of a certain feeling experienced at the moment of filling the questionnaire. The 6 feelings we take into consideration and evaluated from the following statements:

	105	+1. I feel sad
	106	+1. I feel content
	107	+1. I feel calm
	108	+1. I feel tired
