1 +# OB01: Prevent user from going out.
2 +In many cases, we do not want the person with dementia to go out at all: it is likely that they go out for the wrong reasons, and the chance that they get lost is high. Because of this, in many cases, the first objective the robot tries to complete is to prevent the user from leaving the building.

3 -In many cases, we do not want the person with dementia to go out at all: it is likely that they go out for the wrong reasons, and the chance that they get lost is high. Because of this, in many cases, the first objective the system tries to complete is to prevent the user from leaving the building.
4 +## OB01.1: Object to reason for going out.
5 +The user may want to go out because of a specific reason. If this is the case, the user can try to come up with an argument against that reason to try to convince the user to stay in. For example, if a user wants to go to work, the robot might argue that as it is weekend the office is closed. For a supermarket, on the other hand, the robot might say that either the groceries the user is looking for are already in the fridge, or someone else has already gone out to get the things they're looking for and will be back any minute. As this will likely remove the incentive the user has for going out, this might just be enough to have the user stay in.

For example, if a user wants to go to work, the system might argue that as it is weekend the office is closed.

This will likely remove the incentive the user has for going out, presumably making them decide they may just as well stay in.
7 +## OB01.2: Bring user back to reality.
8 +If a user is really confused about where they are, they might need a reminder to tell them they should not go out and instead stay in. Such a reminder could, for example, be provided in the form of a song associated with the current location. The user will recognise the song and be reminded of where they are, making them realise there's no need to go out.

8 -=== OB01.2: Bring user back to reality.===
9 -If a user is really confused about where they are, they might need to be reminded of their current situation. Once they realise who and where they are, they will probably realise by themselves that it is not a good idea to go outside and that they should instead stay in. A reminder could, for example, be provided in the form of a song associated with the care home, the name of a caretaker who is inherently bound to their memory of the place, or an image they often see around the care home. If this cue is correctly recognised by the user, they will likely become aware of their current state and as a result reconsider their plan to go out. If this plan was really only conceived because of their confused mental state, they will come to realise they should not go out.
10 +## OB01.3: Keep user occupied inside.
11 +A different reason for a user to go out might be plain boredom. If they have nothing else to do, they might want to go for a walk and enjoy the scenery. There is effectively nothing wrong with this, besides the fact that it is simply not convenient. In this case it would probably work if the robot would be able to entertain the user somehow. This could be in the form of a game, a cup of tea or anything else.

12 -A different reason for a user to go out might be plain boredom. If they have nothing else to do, they might think of a reason to leave the care center, for example to go to run some errands. There is effectively nothing wrong with this, besides the fact that it is simply not convenient. In this case it should work if the system finds an alternative way for the user to amuse themselves. The system will try to achieve this by suggesting one of several alternative activities to the user. As these activities are indoor activities, users agreeing to do the suggested activity will no longer want to go outside.
13 +# OB02: Alert caretakers of user that user has gone out.
14 +There might be cases where the user is determined to go out, and the robot does not have the proper skills to stop them from doing so. In such cases the robot might be somewhat powerless, but caretakers or family members of the user might not be. Because of this, a second objective of the system is to alert caretakers if the user cannot be prevented from going out. This way, caretakers can quickly respond to this action and prevent many of the negative consequences by quickly finding the user and bringing them back home.
13 13  
14 -=== OB01.4: Allow for quick intervention from the caretaker.===
15 -If the system tries to convince the user multiple times but the user does not budge, the caretaker should intervene. This caretaker can provide a more appropriate and personal response, or even deploy physical measures such as touch - something the system cannot do. However, if we want the caretaker to fulfill these fuctions, the caretaker needs to be aware that they are needed at the door. The system will allow for this by sending a notification to the caretaker, so that they can immediately go to the door and help the system keep the user safe.
16 +# OB03: Guide the user when going out.
17 +Some users might have legitimate reasons for going out, or cannot be convinced to stay inside, but do listen to what the robot has to say. In such cases, the robot will accompany the user on their stroll and make sure they find their way back home safely. This way, the user can be allowed to go out, without any of the negative effects.
16 16  
17 -= OB02: Allow user to take supervised walks.=
18 -There might be cases where the user does not fall in the above categories, and simply wants to take a walk. This is, of course, not something we want to fully prevent the user from doing. For this reason, the system will alert the caretaker of this situation when it occurs. The caretaker will then proceed to accompany the user on their stroll to make sure they are prevented from getting lost. This way of superwised walking will prevent wandering while still allowing the user to get some fresh air every once in a while.
19 +## OB03.1: Keep user alert.
20 +During their stroll, the user might be tempted to walk on autopilot. As this function might be impaired because of the dementia, this could have them end up in unexpected places. By using simple interactions and asking questions about the route they're taking, the robot will be able to make sure the user keeps following the intended route and thus keep them out of dangerous situations.
21 +
22 +## OB03.2: Guide user home when lost.
23 +Despite the robot keeping the user alert on the route, there might be situations where users completely forget where they are or how to get home. In order to deal with such cases, the robot is equipped with GPS. If the user and the robot find themselves in an unknown location, the robot will determine the fastest route back home and guide the user along this way.

1 -I think we can remove the OB03.1 and OB03.2. OB03 describes the situation well enough.

1 -Very good that you have concrete ideas about the functions of the robot. Try to formulate the objectives more in relation to the values of the stakeholders. E.g., "Provide a safe environment for the residents to walk around on their self (support autonomy)"; "Detect conditions of disorientation, when they appear, and mitigate the problems, preventing residents to go outside in such a condition". Alerting etc. are the robot functions that serve these such objectives.
