+Prior to the experiment, participants were asked to simulate the experience of a person with dementia. Participants who wore glasses were asked to remove them, while those who did not were provided with short-sighted or far-sighted glasses to replicate the blurred vision and degraded perception that is common in PwDs. Additionally, their index and middle fingers were taped together to simulate the difficulty in controlling movements that many PwDs experience. |

+For this experiment, we used a between-subject design. The control group interacted solely with the stand-alone application, which represented the robot without voice functionality, and received guidance through a single task paper. In contrast, the experimental group engaged with the fully-functional robot, which provided audio instructions, guidance, and encouragement. |

-Two quantitative measures are used in the user evaluation: the first is to test different attributes including accessibility, trustworthiness, and comprehensibility; and the second is System Usability Scale (SUS). |
|
71 |
+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 software. |
| 91 |
91 |
|
| 92 |
|
-**Interpretation for user evaluation ** |
|
73 |
+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. |
| 93 |
93 |
|
| 94 |
|
-If a respondent had a minimum total score of 60% (15 out of 25 for the matrix question) or more, he or she was considered to be satisfied with the application. |
|
75 |
+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. |
| 95 |
95 |
|
| 96 |
|
-**Scoring SUS** |
| 97 |
|
- |
| 98 |
|
-* For odd items: subtract one from the user response. |
| 99 |
|
-* For even-numbered items: subtract the user responses from 5 |
| 100 |
|
-* This scales all values from 0 to 4 (with four being the most positive response). |
| 101 |
|
-* Add up the converted responses for each user and multiply that total by 2.5. This converts the range of possible values from 0 to 100 instead of from 0 to 40. |

| 103 |
|
-**Interpreting Scores for SUS [[*>>https://measuringu.com/sus/]]** |
| 104 |
|
- |
| 105 |
|
-Interpreting scoring can be complex. The participant’s scores for each question are converted to a new number, added together and then multiplied by 2.5 to convert the original scores of 0-40 to 0-100. Though the scores are 0-100, these are not percentages and should be considered only in terms of their percentile ranking. |
| 106 |
|
- |
| 107 |
|
-Based on research, a SUS score above a 68 would be considered above average and anything below 68 is below average, however, the best way to interpret your results involves “normalizing” the scores to produce a percentile ranking. |
