XWiki - Test

Our robot aims to help delay the stage of dementia or slow down the deterioration of memory. The best situation is that we can test the robot with real PwD and in a relatively long time period to see if this robot really works, which is impossible for our project. So our evaluation performs in a group control way. Participants are divided into two groups, group A with the intelligent one, and group B with the dummy one.

= Problem statement and research questions =

The main use cases that the evaluation focuses on are UC001: Daily todo list and UC005: Quiz. Based on the claims corresponding to those use cases, we derive the following research questions:

6

7

1. Are PwD willing to play the quiz?

8

1. Are PwD happy to listen to music?

9

1. Are PwD happy if they get the correct answer?

10

1. Does PwD enhance their memory of the association between music and activities?

= Method =

The control group evaluation is used. One group of participants interacts with a dummy robot and another group interacts with the intelligent robot. The only difference between these two groups is the independent variable - dummy or intelligent robot, which makes our result more reasonable.

Besides, Our group decided to use a mixed-method approach for the evaluation.

18

* Quantitative data will be derived during the experiment such as the number of mistakes the participant makes during the quiz.

19

* Qualitative data expected to be gathered through questionnaires, such as to what extent participants are satisfied with using the robot, is also adopted for evaluation.

By measuring these two types of data, we will manage to assess if our claims are achieved and the research questions are answered.

== Participants ==

We invited 19 participants. To validate our research question that the quiz will help people better memorize music-activity links, participants will be divided into two groups, Group A with the intelligent robot(9 participants) and Group B(10 participants) with the dummy robot.

== Experimental design ==

29

The experiment will be conducted to simulate the reinforcement learning process of musical memory related to daily activities and to investigate if the quiz is indeed able to help with the learning.

=== Evaluation Step ===

34

First, all participants would sign a consent form that informed them of the usage of the collected data and our goal of evaluations.

==== Step 1 ====

In our prototype, users can personalize the link between music and activities based on their existing intrinsic knowledge. But due to the limited time and requiring a comparable result between groups, in evaluation, we forced 6 pieces of music and activities. Participants listened to the music and were asked the remember the associated activities.

==== Step 2 ====

Participants in two groups would play with the robot for 3 minutes. Participants in group A would play with the intelligent robot and group B would play with the dummy robot.

==== Step 3 ====

In the end, the participants would take a quiz to see how much they remembered. They are also asked to fill in a questionnaire including the feeling of the robot and possible feedback.

1. How many questions did you answer correctly? (Points from 0-6)

51

1. You feel the robot can help you remember the task. (Agree, Neutral, Disagree)

52

1. You feel the robot is annoying. (Agree, Neutral, Disagree)
