72 +We asked participants about there sense of being in charge, happiness, safety and trust when walking with MiRo and with the caretaker. In the graphs below we show each sense compared between the two guiding agents.

74 +This comparison shows that when walking with a caretaker the participants felt mostly in charge, whereas when walking with MiRo the participants felt this less frequently.

76 +This comparison shows that both a caretaker or MiRo accompanied positive emotions.
77 +[[image:Safe_graph_comparison.jpg]]
78 +This comparison shows a significant difference between walking with a caretaker and MiRo. A caretaker made the participants feel safe most of the time or prevented any unsafe feelings. MiRo conveyed only minimal feelings of safety with participants answering 'at times' most frequently.

71 71  In addition to the questionnaire, we conducted a short interview with our participant who is hard-of-hearing. Their study was conducted without them wearing their hearing aids.
72 72  We asked them if they thought their experience would differ if they were wearing their hearing aids. Their answer was that the biggest thing was that in a real scenario, the wristband doesn't give you enough information about what to do. It only tells you that you are something wrong. They commented that if they were 83, they would not have enough direction from this, compared to someone who could hear sounds: MiRo could direct them back by barking at the user, for example. However, they mention that if you are severely hearing impaired, there is probably nothing you can do other than vibrating the wristband.
