In the second week of my Basic Introduction to Game Design course, I talk about games as systems, their formal structure and the elements that make games into games.

Cheaper physiological sensors lead to an increased use in the game industry. This post explores past and present applications of biofeedback game interaction and psychophysiological evaluation in game user research.

Using biometrics for psychophysiological evaluation is becoming a popular approach in game user research. While results of this work can look stunning, experimental control is important if you want to interpret your data in a way that is robust.

A research study found that a logic problem-solving game is associated with positive feelings for the elderly but with negative feelings for the young. For all generations, brain-training was more exciting with video games than with pen-and-paper.

Hi Fabian, thanks for the ...

Hi Fabian, thanks for the feedback, very glad that you found this useful. You saw the exact purpose of this article: It is an introduction for people interested in game design that do not yet use designer lenses to view games as systems. It is the blogpost form of one ...

Dennis, this is a great ...

Dennis, this is a great question that we actually thought about close to the end of the development of Biometric Storyboards. Really, what is being generated by the user research and biometric data is a visualization of game structure, much like a plot graph of important game events. So, following ...

Sorry for the late reply, Scott. I think what you mention is quite interesting and would warrant more studies on what exactly is the motivator for playing brain-training games for young and old people. Fear of losing your mental edge certainly sounds reasonable for the elderly, but what about the ...
