Two quantitative measures were employed in the user evaluation. The first measure aimed to test attributes including accessibility, trustworthiness, and comprehensibility. The second measure used was the System Usability Scale (SUS), which is a widely-used scale for evaluating the usability of the software. |

-In addition to the quantitative measures, a structured interview with open-ended questions was conducted. The aim of this interview was to gain a deeper understanding of participants' experiences with the robot, including any concerns they may have regarding the potential use of the system and its functions in a real-life setting. |

By using both quantitative and qualitative measures, the user evaluation can provide a more comprehensive understanding of participants' experiences and perceptions of the system. This approach allows for a more nuanced analysis of the data and can provide valuable insights into the strengths and weaknesses of the system, as well as areas for improvement. |

+=== Limitations: === |
| 107 |
107 |
|
|
138 |
+We ran into some problems while creating the application and performing the experiment: |
|
139 |
+ |
|
140 |
+==== Implementation: ==== |
|
141 |
+ |
|
142 |
+* We could not adapt the robot to the PwD due to time constraints. This means that we did not take into account the severity of the PwD's visual, acoustic and kinesthetic limitations while setting up Pepper. |
|
143 |
+* We could not test the full capabilities of the robot due to privacy constraints. Since we fabricated the information about relatives to protect the privacy of participants, we were not able to perform the scenarios in a realistic manner. |
|
144 |
+* Since the version of the Google Chrome browser on the Pepper tablet was outdated, we were not able to load our Flutter application onto it and simulate actual scenarios. |
|
145 |
+* Participants where from a wide variety of different background and mother tongues, it was therefore not possible to adjust Pepper to the specific culture of the participant. |
|
146 |
+ |
|
147 |
+==== Evaluation: ==== |
|
148 |
+ |
|
149 |
+* It is important to note that the participants who took part in our experiment were not affected by dementia. |
|
150 |
+* The experiment was not conducted in a real-world setting. |
|
151 |
+* We were not able to test the improvement in memory recall since it involves sustained interactions with a particular user over time and our experiment involved brief, one-time interactions. |
|
152 |
+ |
|
153 |
+=== Future Improvements: === |
|
154 |
+ |
|
155 |
+* We can make our system more realistic/adapted to PwD by incorporating human-like responses, gestures and movements to Pepper. |
|
156 |
+* We can make our system fully gesture/voice controlled to enable the PwD to (% style="color:#000000; font-family:Arial; font-size:11pt; font-style:normal; font-variant:normal; font-weight:400; text-decoration:none; white-space:pre-wrap" %)use the system without assistance from a caregiver, increasing their autonomy. |
|
157 |
+* (% style="color:#000000; font-family:Arial; font-size:11pt; font-style:normal; font-variant:normal; font-weight:400; text-decoration:none; white-space:pre-wrap" %)We can incorporate privacy protocols like voice authentication and gaze detection to ensure that all personal information about the PwD, relatives and caregivers are kept safe and confidential. |

|
161 |
+After performing the experiment and running various statistical tests on the results obtained, we have made the following conclusions that hopefully answer some of our research questions: |
|
162 |
+ |
|
163 |
+1. We believe that an information support application **DOES IMPROVE** a PwD's well-being, since it can (% style="color:#000000; font-family:Arial; font-size:11pt; font-style:normal; font-variant:normal; font-weight:400; text-decoration:none; white-space:pre-wrap" %)provide them with access to important information and support, improving their overall quality of life. |
|
164 |
+1. We believe that a robot assistant **DOES IMPROVE** the experience of a PwD using it. The robot(% style="color:#000000; font-family:Arial; font-size:11pt; font-style:normal; font-variant:normal; font-weight:400; text-decoration:none; white-space:pre-wrap" %) can provide companionship and assistance, making them feel independent and less isolated. |

+(% style="color:#000000; font-family:Arial; font-size:11pt; font-style:normal; font-variant:normal; font-weight:400; text-decoration:none; white-space:pre-wrap" %)While our experiment had its limitations, we believe that it provides a foundation for future research in developing personalized memory robots for people with dementia. We also believe that our research is applicable to mobile agents which increases the accessibility of the solution. |
