146	146	In terms of the research question, no significant differences were found between the two different motivational methods. This is however very likely influenced by the circumstances surrounding the design and the evaluation. The design is unfortunately rather limited and with limited capabilities, due to time constraints. Speech recognition didn't always work properly and was not as flexible as desired which made the interactions less realistic for the participant. Things such as elaborating, which would be something that would be a natural part of a leisurely conversation were made very difficult as the robot could not comprehend conversation to the fullest extent.  Since participants were also prompted to give shorter answers and try to keep to things like "yes" and "no" it greatly influenced how participants interacted with the robot.

148		-There were also other constraints to the interaction, which had to be given as instructions to the participant before testing. These things included at what distance to stay from the robot, when to join the robot's side when it's time for the walk, how long to wait to speak after a certain prompt, and when to repeat themselves. This further made it unnatural but was necessary for the system to perform properly. Ideally, an individual would be able to join the robot's side at any given moment and the robot's movement would not be impacted by the fact that the participant stands too close. Further, one component that has a very significant effect on the results was that it was not possible to test the design with PwD. This was attempted to be resolved by providing a persona description for participants to keep in mind during the testing, but it is difficult to simulate conditions of dementia. Only one participant ended up embodying this character to the fullest extent which was very valuable for the sake of the evaluation but was not enough to explore the concept entirely.

On one hand, it could be positive, since we have all researched dementia and have gained a lot of knowledge within this which could make us better at simulating appropriate behavior with the robot or testing the systems in a reasonable way. But since participants also have an idea of how the robot works prior to the evaluation, based on their own experiences of working with the robot, perhaps some mistakes or issues went undetected. For example, a completely inexperienced user could potentially show other faults in the design that appear only if the system is entirely foreign to the user, which is likely what it would be like with a PwD. Of course, knowing about dementia is not the same thing as actually suffering from the diagnosis, so many aspects have most likely gone undetected there for that reason also.
