For years guarding and investigating real environment has been a domain of human activity.
However, nowadays more and more often mobile robots are used to this aim.
In case of static environment, planning a minimal robot's tour to see all
what is needed to see is well known problem. The art gallery problem
and the watchman problem concern this case and they have already found numerical solutions
However, if the environment changes rapidly then a mobile robot is,
at least partly, driven by an operator. Human factor is then crucial
as far as quality of detecting changes is concerned.
The game is similar to a flight simulator. Virtual robot tours a designed scene
driven by the player (robot operator). The scene describes
The operator is equipped with a map of initial scene state.
All the objects are marked on the map and described.
The player does not know how often the changes occur although he knows
that the objects may change position or color, appear or disappear.
The player knows punishment function.
Before the game starts every player have to register entering a login and a password (picture below). When the player connects the game for the first time it is required to mark the box " Create new player".
If the logging is successful, the name of the next board will be presented to the player. The game starts after pressing the button "Start" (picture below).
When the game starts time begin to be counted. The player moving in the given path (red line on the picture below) has to find every change of the environment before a deadline. Time, position and frequency of changes are not known to the player.
The player can move pressing arrows shown on the picture above or arrows on a computer keyboard:
In order to take a picture the player should press "camera button" on the picture above or a space bar. When the player wants to report a change he should point at a position on a map (picture above) and press a left mouse button or press a button "Object changed" (picture above) or press a return key. Then the player should enter position and type of the change (picture below).
When a button "Show grading scale" is pressed current grading scale is shown (picture below). The grading scale may change during play.
Initial number of points: 100.
