  November 2
• Part II will be assigned then and will be due on
  December 10
• Note that the project demos will be on December 4

Project Description Part ITask 1

• Implement a simple application comprising two key
  modules
• A 2-D grid representing a physical area, with an
  object located somewhere within the grid
• A user-driven interface issuing commands for
  moving to a specific location within the 2-D grid

4
2-D Grid

• It should be at least a 10x10 grid
• Units of distance are unimportant
• This is a virtual environment
• There must be at least 3 obstacles within the
  grid
• The object moves only along the grid lines

7 8 9 10

User Commands

• A system user can issue the following commands
• placeObstacle (gridloc x, gridloc y)
• placeObject (gridloc x, gridloc y)
• moveObjectBy (int x, int y)
• moveObjectTo (gridloc x, gridloc y)
• Once a user issues a command to move the object,
  the objects movement must be animated on the
  grid
• The object must be displayed at each step
• If the user has requested the object to be placed
  in a location that is blocked by an obstacle, the
  object returns to its original location once it
  has hit the edge of the obstacle
• If the user has requested the object to be moved
  along a path blocked by the obstacle, the object
  must return to its original location and try
  alternative paths
• If the user issues a command to move the object
  outside the grids boundary, the object should
  attempt to move until it reaches the boundary, at
  which time a warning must be displayed to the
  user, and the object will remain at the final
  location reached

Task 2

• Functionally equivalent to Task 1
• The user command interface is enhanced to include
  a grid.
• The object is given instructions for moving by
  having the user click on the Move button and
  select a location on the grid.

Task 3

• The number of objects to move is increased to two
• Each object is given instructions for moving by
  having the user click on the appropriate Move
  button and select a location on the grid.
• Note The two modules GUIs must be synchronized
  at all times

Task 4

• Functionally equivalent to Task 3
• It involves distributing the two modules across
  twoPrism-MW Architecture objects
• It can still be done on the same network node,
  but in different processes

Task 5

• At least the User Command module (which may
  consist of multiple components) is moved to a PDA
• It interacts over the network with the node
  containing the 2-D grid and the two objects
• A wired link is acceptable initially, but
  eventually must be moved to a wireless link
