The Wristbands

It might be time to clarify how our wristbands work, since we have mostly focused on the screens up to this point. 

When designing the wristbands we had a few things in mind. 

1. What function do we want them to have in our system?
1. Give the system information about the position of the user.
2. Give the system information about the interaction of the user.
3. Give the user information about when he/she has new questions to answer.
4. Give the user feedback about points gathered that the screens can't provide.1
2. How are we going to incorporate this function into our bracelet?
1. Give the system information about the position of the user.
1. Using RFID technology, we can have passive RFID-circuits integrated in the wristbands that are activated when they come close to a reciever unit.
    
2. Give the system information about the interaction of the user.
1. This is solved using the same technology as mentioned above, RFID. When the RFID tag is active at a certain location for a longer period of time, we can be relatively certain that the user has been reading or in other ways interacting with that part of the museum.
3. Give the user information about when he/she has new questions to answer. 
1. This problem, however, can not be solved with the RFID-chip. Here we want to use lights to aware the user of the awaiting questions.
4. Give the user feedback about points gathered that the screens can't provide. 
1. We want to solve this problem using the same technology as mentioned in point 2.3.1 (above). Although we can't use the same colour of the light. We solved this by using the colour green for letting  the user know that points have been gathered and blue for awaiting questions. We picked the colour green because it has positive connotations (green-light traffic signal etc.). The reason for the colour blue was that we didn't want the user to feel stressed out about having to get to a question-screen in order to answer his/her questions. Since blue has proven to be a calming colour, we much rather wanted to use it instead of, let's say, red.
3. How can we make the bracelet as cheap, hygienic and simple as possible?
1. In order to make them cheap, we want to manufacture them out of paper. Here we drew a lot of inspiration from the temporary cards that SL use for travellers who only buy tickets that lasts for 24 hours. These are made of paper and also incorporates an RFID circuit for getting past the turnstile. 
2. This is also hygienic because visitors will get their personal bracelet which will not be reused by any other visitors.
3. Keeping it to only 2 lights and a circuit is the most simplistic design we could think of. 
4. In order to be enviromentally aware, we want to reuse the circuits and LED-lights from used bracelets. We therefore encourage the user to leave their bracelets for recycling. 

1. The things we had in mind here was mostly competative parts of the exhibition that is not incorporated with the screens and doesn't require you to remember facts. For an example, at the Museum of National History, at the exhibition about humans, there is a part about monkeys where it says: "A monkey can hang from a tree for X miniutes, how long can you hold on?". Here they have a "branch" sticking out of the wall with sensors built into it in order to record how long you can hold on. As it is today, your time is displayed on the wall for a few seconds and then disappears. With NILS, we want your score to be recorded and incorporated into our Knowledge Hunt. This particular part doesn't include interaction with a screen of any kind, but is a rather physical activity, which creates the need for different feedback.
