| 2 | = OB01: Prevent user from going out.= | ||
| 3 | |||
| 4 | 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. | ||
| 5 | |||
| 6 | == OB01.1: Object to reason for going out.== | ||
| 7 | The user may want to go out because of a specific reason. If this is the case, the robot 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. | ||
| 8 | |||
| 9 | == OB01.2: Bring user back to reality.== | ||
| 10 | 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 realize there's no need to go out. | ||
| 11 | |||
| 12 | == OB01.3: Keep user occupied inside.== | ||
| 13 | 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 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. | ||
| 14 | |||
| 15 | == OB01.4: Alert caretaker if user refuses to stay inside.== | ||
| 16 | If a the robot tries to convince the user multiple times and the user does not budge, then the robot should alert the caretaker. The caretaker will then take over the role of convincing the user to stay inside or distract them in some way. | ||
| 17 | |||
| 18 | = OB02: Alert caretakers of user that user has gone out.= | ||
| 19 | 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. | ||
| 20 | |||
| 21 | = OB03: Guide the user when going out.= | ||
| 22 | 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. The user may want to go out for a walk, and in that case, we do not want to take away their freedom. In such cases, the robot will alert the caretaker and the caretaker 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. | ||
| 23 | |||
| 24 | == OB03.1: Keep user alert.== | ||
| 25 | 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. | ||
| 26 | |||
| 27 | == OB03.2: Guide user home when lost.== | ||
| 28 | 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. |
