The death of three lines

This multiperson game assistant would display lines on the "ground" around enemy players. The lines would have different colors and correspond to possible positions the enemy player would likely occupy in the future.

It would be done thusly:

The computer would observe the enemy's activities over time and check for repeated movement styles. For example every time the player has shot ten rounds he ducks behind something. Almost every time there's a wall in front of her she throws a grenade. Almost every time he's running an there's a wall to his left he stops for half a second to assess.

The computer would build these observations into a prediction algorithm for that player and make guesses about what the player would do.

If the uncertainty is too high the lines would not be displayed. Color of the lines could indicate degree of certainty (e.g. "she has stopped at that corner the last ten times she approached it" would be a very high level of certainty.)

It would use any information about the person's level of experience to assume higher or lower chances of optimum actions (not making newbie and/or random choices)

Finally it would calculate the maximum distance possible for that character to travel in a given number of milliseconds and display it as a series of concentric irregular shapes.
