There are five segments of interaction; pick one and analyze it using the principles we have discussed in class, and as outlined in the papers read for this past week.
The world view shows the state at the beginning of the segment, or at some other point as noted. For complex situations I have given multiple world views, and labelled them according to which round of execution they represent.
On the world view, squares are barrels of toxic waste; red ones are ones that have at some point been seen by the users, though they might not have noted them. The tug is the circle; crane1 is the circle with a tail and the letter "D" in it, for 'dredge'; crane2 is the one with the "N" in it. When the circles are filled it indicates that their equipment is deployed; when the two crane circles are linked it indicates they have joined together to handle a large or extra-large waste.
The diamonds are small barges; if they are filled in it indicates one or more wastes are on the small barge. The large barge is similar, except that it is represented by a triangle.
Markers appear in yellow on the map; they are only visible to one user. If I felt the markers are important, I turned on the markers created by one user, indicated which user that was, and added the marker window.
In all cases I have also given you a snippet of chat.
In the chat transcript, there are periodic lines like:
: ---- starting round 15 ------------------------This indicates the point at which the users submitted their plan. Occasionally, there are multiple blank lines in the chat, such as:
crane2: crane2: crane2: crane2:This is due to a minor bug in the system (since fixed); these lines were visible to the user, but probably do not indicate anything -- perhaps unlike a chatroom, where people sometimes insert a number of blanks to get people's attention, or somesuch.
