4	4	For the prototype that we have designed now, these are some research questions that we want to address.
5	5
	6	+1. Are PwDs able to use our prototype smoothly?
6	6	1. Can medication/meal/activities reminders help PwDs to improve their lives?
7		-1. Are PwDs able to use our music software smoothly? How robot can support people with dementia in accessing, enjoying music with personal meaning?
8	8	1. Can activity breakdown help people better manage their lives? The effects of using such technology in a natural setting.
	9	+1. Does the robot have a positive effect on people’s emotional state?
	10	+1. How do participants respond to the music? How robot can support people with dementia in accessing, enjoying music with personal meaning?

16		-For this study, we intend to find 20 people. the participants will all be early-stage dementia patients and we will make sure to include at least 5 males and 5 females to avoid gender imbalance. the group will include at least 5 people that are 50 or younger and we expect most of the other participants to be between 75 and 90. The participants will all join the same 3-hour session and will be given 5 to 10 minutes to perform their tasks.

18	18	== Experimental design ==
	21	+Since our evaluating process is relatively short, we use within-subject, which means each participant goes through all conditions. In this way, our experiments tend to have more statistical power and less variability.

21	21	== Tasks ==
	24	+All participants will go through our designed testing process, which includes medication/meal/activity reminder, listening to the music, activity breakdown.
	25	+1. Medication/meal/activity reminder: The robot will remind the patient of daily activities, through which we can see the effectiveness according to their reactions.
	26	+1. Listen to music: PwDs will test some music functionalities in this part. PwDs can choose music by themselves by interacting with the robot or they can listen to random music which is picked according to their preferences.
	27	+1. Activity breakdown: In this part, the robot will break down some complex tasks into a list of simple tasks and PwDs can follow the steps to accomplish complex tasks.

23	23
24	24	== Measures ==
	31	+We are planning to measure our prototype both behaviorally and emotionally. Behavior data is the actions that PwDs take when interacting with the robot, which is the quantitative data. Emotional data is the change of expression and emotional state, which is the qualitative data.

27	27	== Procedure ==
	34	+All PwDs are going to complete the evaluation separately. We will simulate a home setting, which is the most common scenario for PwDs. At the start of the evaluation, all participants will be gathered in the same room, together with the researchers and relatives. We will explain the whole evaluation process, provide simple instructions, explain that participation in the evaluations is voluntary, and participants are free to stop the evaluation at any time. Then, we will explain how the gathered data will be analyzed and help us to improve our prototype.
