5	5	= Future Work =
	2	+The current robot called MiRo has some limitations that prevent it from truly accomplishing all objectives set for it. One of the limitations of the MiRo is that it is unable to walk on floors that are either uneven, carpeted or black. A new robot prototype should be able to walk up small steps to allow the person with dementia to also walk outside.

7		-= Snoezelen with MiRo =
8		-Snoezelen with the robot dog is unfortunately not possible with MiRo due to MiRo being limited in a couple of different areas. First of all, MiRo is very fragile. When one touches MiRos head, it moves a bit down each time. Secondly MiRos lights are just a few small LED lights. As Snoezelen would be done by elderly people who might have a visual impairment, it would be preferable to have bigger or more diffused lights so the PwD are able to see a change in colours. Finally, when people are petting the dog, it might be better if the robot dog would have some fur, it would feel more realistic.
9		-Future work would include incorporating Snoezelen. To incorporate Snoezelen, a new prototype of the robot should be created, once a new prototype has been created, an evaluation on how useful Snoezelen is with this new Prototype should be done as well.
	4	+The robotdog should be able to connect with the caretaker if something happens were additional assistance is necessary. Therefore, the dog should have some way of contacting the caretaker, either over data roaming or wifi. The robotdog should also have a GPS so the caretaker can locate the robotdog and, more importantly, the person with dementia if they are lost or refusing to follow the dog.

11		-== PwD who likes Snoezelen ==
	6	+When the person with dementia is on a walk, the dog should listen to a name that has been created by either the carehome or the individual person with dementia. When the dog can listen to a name, it can respond to its name like a real dog. The person with dementia could get a better bond with the robotdog if they were able to give it a name which it would respond to. Finally, if the dog listens to its name, it can stop walking and start paying attention the the user to see if it would need something from the dog.

	8	+Currently, the robot is unable to walk a path that is not entirely hardcoded. The robot should be able to follow a predefined path and should be able to differ from that path if an obstacle is detected.

15		-The sensory stimuli produced by the Miro can calm down the PwD when they are distraught. Snoezelen helps with the stimulation of one's mind and encourages PwD to pet the miro to observe a spectrum of LEDs and listen to calming and relaxing sounds.
	10	+Finally, the new version of the robot dog should allow for Snoezelen. The dog must not be too fragile so people can pet the head and body of the dog. Preferably, the skin of the dog should be soft or nice to the touch so petting it would be more preferable than petting a hard plastic dog like the MiRo.

	12	+== Snoezelen ==
	13	+Next to this, MiRo should not only be a guiding robot, it should also pose itself as a companion. For this, MiRo should allow for 'Snoezelen'. Clients should be able to pet MiRo on its head and body, and it should respond to that affection with happy noises and movements. This helps the client to create a bond with MiRo and it makes walks with MiRo more enjoyable. We did take Snoezelen as a secondary function into account for our [[Ontology>>https://xwiki.ewi.tudelft.nl/xwiki/wiki/sce2022group02/view/Main/Ontology/]], [[Use Cases>>https://xwiki.ewi.tudelft.nl/xwiki/wiki/sce2022group02/view/Use%20Cases/]] and [[Claims>>https://xwiki.ewi.tudelft.nl/xwiki/wiki/sce2022group02/view/Claims/]].

19		-If the PwD has any auditory or visual impairments, these could alter the experience and the effectiveness of Snoezelen with Miro. In addition, epillepsy, sensitive hearing or similar sensory disorders may cause the PwD to be overwhelmed. As such, the Miro should be able to adapt to each different PwD. Modifications include: changing the volume of sounds, removing (relatively) high-pitched noises and removing visual patterns that may induce epilleptic attacks.
	15	+However, as we were not able to test Snoezelen, our evaluation of this function is limited to a conceptual empirical setup which is described as follows. The research question (R4) would be phrased as: how do users react to Snoezelen with a moving robot? To answer this exploratory question empirically, we would embed a between-subject study design where participants would be divided into three groups: stationary, limited movement and free movement. Multiple sessions (e.g. more than three) would be preferable to mitigate the novelty effect of engaging with WAF (i.e. the MiRo) for the first time.

21		-== PwD who dislikes Snoezelen ==
	17	+In the first group, the MiRo would only make sounds and blink LEDs. In the second group, the MiRo would wag its tail and turn its head at times. In the last group, the MiRo would move in all directions, so roll forwards, backwards and side-to-side. Using the first group as a base condition, we could use metrics such as heart rate and the PwD's own experience to compare between each group and see if Snoezelen with a robot that expresses more degrees of moving freedom either overwhelms (e.g. too much stimuli caused by movement of MiRo) PwD or rather stimulates them (e.g. makes them more energetic). To allow the PwD to describe their own emotions perhaps more accurately, the AffectButton [[(Broekens & Brinkman, 2009)>>http://dx.doi.org/10.1109/acii.2009.5349347]] could be used to provide feedback.

23		-=== Positive effects ===
	19	+Ethically, we would have to accommodate PwDs who are hypersensitive to certain stimuli by making sure they only participate in the base control group (i.e. the first one) or to exclude them if they are known to suffer from epileptic seizures. Naturally, this study would take on the form of a field study rather than a lab one as the discomfort of PwD can be a major factor in the outcome of the results of such an experiment.

25		-Even if the PwD is disinterested initially, they may still have the innate desire to explore the association between touching the Miro and its response. If the PwD then decides that it is not their cup of tea, they were at least suggested a new activity that stimulated their mind. Else, they may become fond of Snoezelen in subsequent sessions.
26	26
27		-=== Negative effects ===
28		-
29		-Similar to the negative effects for PwD who are into Snoezelen, PwDs may get traumatized when the Miro expresses unexpected behavior or overstimulates them. These effects are augmented when PwD has no inclination for Snoezelen or similar activities at all.
30		-
31		-== Claim ==
32		-
33		-Whether the PwD likes/dislikes Snoezelen at first seems irrelevant for the outcome that PwD will become either more relaxed at best or not bothered at worst by the Miro at all. In order to justify this claim, the Miro must be programmed to accommodate for sensitivity of each PwD. As failing to do so, may cause long-term trauma or injury for PwD.
