Assignments can be performed by accessing the website and existed in different types.
Wishes allow people to post a wish and assign a reward to it. Each player started a campaign with a total number of ‘wish credits’. By assigning a number of credits to the wish, this number is deducted from the player's total number of wish credits. The amount of wish credits assigned to the wish set the reward that could be gained by fulfilling it.
Questions are a type of assignment that allowed players to answer a specific question asked by the neighborhood coaches, either through a multiple-choice answer or through an open, full text answer.
Geo Challenges allow players to map points on a digital map of the area, as a response to a certain location-oriented question like ‘what is the dirtiest spot in your neighborhood?’. The number of spots a player can map can be set in the Geo Challenge’s settings. In addition, a peer-evaluation mechanism can be activated, requiring other players to validate the points that were added by their peers.
Open assignments offer an easy way to extend the system with generic assignment descriptions. Where user actions in the other assignment types result in the automatic increase of player scores, this is not the case for open assignments. These requir the community coach (the person who creates the assignments) to manually (using the server’s administrative back-end) add the correct number of points to the correct player when an open assignment is fulfilled. For example, during the Ghent trials, open assignments were performed through Facebook. We created a ZWERM Facebook page, which gave us extra viral exposure to draw players to the game and a familiar place for players to express themselves. Example assignments were the posting of photos on Facebook according to a certain assignment description, like “Post an original way to check-in at the Hollow tree on Facebook”. When players did this, the community coach would assign the correct number of points.
Events (e.g. handing in spent batteries, garage sales,...) can be organised and points could be obtained for participating in them. This is done through the combination of a tablet or smartphone with a bleutooth RFID reader. By scanning the participant's RFID card, the participant scores points.
