Dynamic Difficulty Balancing for Cautious Players and Risk Takers

Figure 5

Example of how the particle filter incorporates new evidence on each frame (Figure adapted from Hawkins et al. [29]). Note how the player tracks evidence adjusting their belief at each time step. The number of particles in the model relate to the player's ability to do this tracking. Players will make a choice about the target when evidence exceeds some decision threshold. The amount of evidence required is related to the players risk profile.
