  15. 15. Player Data Visualization • Mixed visualization of qualitative and quantitative player data overlaid on top of a level • The overall hue of the paths conveys areas with high (B and C) and low (A) player arousal Pejman Mirza-Babaei, Günter Wallner, Graham McAllister, and Lennart E. Nacke. 2014. Unified visualization of quantitative and qualitative playtesting data. In CHI '14 Extended Abstracts on Human Factors in Computing Systems (CHI EA '14).ACM, NewYork, NY, USA, 1363-1368.

  16. 16. DEVELOPER GUIDELINES 1. Use visual experience representations whenever possible. 2. Give players functionality to annotate their own experience, physiological or otherwise. 3. Set individual threshold markers when trying to track down emotional moments. 4. Tie player performance to spatial player information and virtual locations to improve design.
  17. 17. DEVELOPER GUIDELINES 5. When researching game flow, simplify the dimensions to facilitate experience coding. 6. Built tools that provide quick and actionable insights, do not overemphasize theory. 7. Allow user researchers to drill down deep into your data at points of particular interest. 8. Facilitate inter-developer collaboration, especially between games user research and game design.
