68 -Twenty University students participated in the controlled experiment (M= 45%, F=55%). After gaining consent through the consent form, all participants were briefed to act as if experiencing the interaction from the viewpoint of a PwD. From the sample, half were asked to interact with the NAO and half were only using a voice-based version of the encyclopedia prototype.

70 -The main finding of the experiment is on Relatedness as can be seen in Table 1: the increase of affect in both Arousal and Valence dimensions during the experiment with the test group was higher than the experiment with the control group. The control group mean values in arousal and valence show no significant change at all.

92 92  
93 -The ecological validity of the study is impacted by the fact that there were no PwD in our sample. The scope of the experiment was limited to TU Delft University students. That means that future research may benefit from a closer approach to an experiment which is closer to the experience of PwD. Moreover, the controlled experiment was restricted to a cohort of 20 participants, underscoring the potential for enhancing result validity through the utilization of a larger sample size

122 122  
123 -With regards to our final insights, there were some areas of improvement. For example, relating to the validity of the testing procedure, we had a relatively small sample size and none of the participants had dementia. This means that the target group for this NAO system was not tested. It was also only a specific group of people, namely students with the age range of 20-25. There was also a level of ambiguity in the point system of the evaluation and with regards to the LLM model focus, we found deviations from the GPT regarding the main objective. However, although these were a few of the limitations throughout the process, we were still able to evaluate the NAO system and could recognise that the NAO may positively affects participant’ s affective state.
