6	6	==== Guiding a patient along a path ====
7		-To function as a walk-guiding robot, WAF needs to be able to follow a predetermined path. To do so, WAF must be programmable with various walking routes. We assume that, in general, people with dementia are not able to choose and/or set up good/suitable walking routes by themselves, and therefore we think that placing this responsibility at the activity coordinator is the best option. The coordinators must be able to set up new walking routes through an online portal in which they can draw a route on a floor plan of their building or a map of the outside area. The coordinators must also be able to create profiles for each of their patients to specify a walking plan containing suitable routes. WAF must then be able to follow this route correctly, avoiding objects or people that might hinder WAF along its path.

9	9	==== Ensuring the patient stays on path ====
10		-During the walk, people with dementia might get distracted, strike a conversation with someone or take a break, causing them to stop following WAF. WAF must be able to notice this so that he does not leave the PwD behind. Then, WAF must be able to wait and regain the attention of the patient to continue their walk.

12	12	==== Altering caretaker ====
13	13	A situation might occur during the walk where WAF needs the help of a human, in this case, a caretaker. A patient may fall, causing them to need someone to help them stand up or to assist them when an injury occurs. Additionally, WAF might ultimately lose the patient, at which point he must be able to alert the caretaker, notifying them of their position such that the patient can be found again.

18	18	====Voice control and customisable names====
19	19	To allow for more sophisticated interaction between the patient and WAF, WAF should be able to listen and respond to voice commands like an actual dog. For example, voice commands could be used when the patient wants to take a break, instructing WAF to stop for a moment. Additionally, it could increase the bond between the patient and WAF if WAF was programmable with different names, allowing patients to give him a personalized name.

30		-The patient can start a walk by indicating to a caretaker that they wants to take a walk (for example in the form of a button). Once the patient presses the button, a caretaker will come to bring WAF. The caretaker will also give the proximity bracelet, see the next section for its description. WAF will then either automatically choose a suitable route or get instructed by the coordinator for a specific route.

32	32	Once the route has been started, WAF walks ahead to show the way. When approaching turns, WAF indicates which way to go by slightly moving towards the desired direction and moving his head to indicate the turn. When the patient does well (e.g. follows WAF consistently), WAF gives positive reinforcement in the form of excited sounds and a wagging tail.
