Positive and Negative effects for each stakeholder:
For each of the stakeholders, there are several positive and negative effects we expect our system to have. On this page, they are listed for each stakeholder, with the distinction between positive and negative effects. Not all of these effects might be applicable to each use case, as the use cases take on different approaches and tackle different problems - with different solutions and outcomes of course.
Person with dementia:
The person with dementia is the central stakeholder in the developed system. The system has been designed mainly for their safety. The different actions the robot takes can have several effects on their emotional state, as well as their physical condition. The most important and frequently appearing ones are shown below:
| Claim | Positive/Negative | Description | Explanation |
| CL01 | + | The user is prevented from getting lost | If the interaction with our system is successful, it will prevent the the person with dementia from going out. If they are in the safe comfort of their care home, there is no way they wil get wrapped up in dangerous or stressful situations outdoors. This could prevent both physical and mental injuries, and can thus be considered a very positive effect. |
| CL02 | + | The user's mood is improved | As the system will be as friendly and helpful as possible, an annoyed user may be relieved after talking to it. The music used may also bring about positive emotions in the minds of the people interacting with it. |
| CL08 | + | The user is subtly brought back to reality | If the user is in a mentally disoriented state, the system will try to subtly remind the user of their current situation. This is done through hints at the caretaker, someone they know who is purely associated with the care home, but also through music and alternative activities. This may not have a large effect on all people, but should be enough to bring some of them back to reality. |
| CL09 | - | The user feels they are losing their freedom | In cases where the user is not brought back to reality, they might feel like they are being kept in against their will. This can make them discontent, and possibly even angry. |
| CL13 | - | The user gets annoyed by the robot | Despite the system being friendly, some people might be annoyed by its ways. For example, if someone who dislikes puzzles gets told to do a puzzle, they may be very reluctant. If they see the caretakers as somehow evil, they might even feel like they are being tattled on by something that is supposed to be their robot friend. This is not good for their attitude regarding the system. |
Caretaker:
The second important stakeholder of the system is the caretaker. By preventing people with dementia in the care home from going out, the system aims to give these people more time to take up the important tasks around the home without having to worry about people leaving. For these stakeholders, the most important effects are once again listed.
| Claim | Positive/Negative | Description | Explanation |
| CL11 | + | Caretakes have more time to tend to other matters | As previously described, the system is aimed at making sure people don't leave the building to make sure the caretaker does not have to. As the caretaker does not need to constantly supervise people at risk of doing so, they can complete other tasks in time that would normally be spend watching the people with dementia. The system also cuts down the time caretakers might normally need to spend to bring wandering people with dementia back to safety. + Less time is needed for convincing PwD to stay inside because the caretaker will only be notified in severe cases. |
for the family member:
+ No longer have to worry their loved one is lost.
+ Spend no more time searching for their loved ones.
From these aspects follow the claims:
+ CL01: The PwD does not leave the care home without the caretaker
+ CL02: PwD's mood is improved
+ CL03: The robot is able to understand and interact according to the PwD's intention
+ CL04: The music fits the intended situation or place
+ CL05: PwD leaves care home with a caretaker
+ CL06: The robot suggests activities to distract people from wandering/leaving the building
+ CL07: The robot is able to notice the PwD and get their attention
+ CL08: Bring PwD back to reality
- CL09: PwD feels he/she is losing their freedom
In order to make the user feel like they still have some freedom, they are not completely stopped from leaving the building. The user is allowed to go out, but with some supervision, to ensure that they are still safe. In addition, when Pepper tries to stop the PwD from leaving, it does not actively block the PwD's path, but rather tries to convince them to stay inside. The PwD still has the choice of not listening to Pepper and making an escape.
- CL10: The PwD feels dependent on others
The PwD can feel dependent since he/she is not allowed to go out for a walk by him-/herself. However, this is only to ensure their safety and the concern of their family and loved ones. However, to make them feel independent, we provide them with some tasks that can be done independently such as going to the living room, or solving a puzzle. These are activities that can be done on their own and thus make them feel somewhat independent.
+ CL11: Caretakes have more time to tend to other matters
+ CL12: Family members
