25 -The main research question can be answered using a within-subject design in order to be able to measure the //increase// per subject. The learning effect will be mitigated, because the two juxtaposed settings are vastly different. So, there is no advantage for the participant to be subjected to two conditions serially. In addition to the questionnaire, notes will be taken during the experiment of the observations of the participant's interactions with WAF (Walking Assisting Friend).

108 108  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.
109 109  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.
