Effective Feedback Procedures in Games for Health.

Feedback on game performance can be provided in many ways (e.g., cumulative points on game achievements, points on selected aspects of game play, biofeedback, brief statements offered during gameplay on choices made, verbal feedback at end of gameplay on overall performance, etc.). Feedback could be used motivationally to maintain player interest and involvement, informationally to guide the player in more effective choices, to build player confidence, and for a variety of other purposes. Although diverse feedback types and purposes are possible, some are more likely to be useful and effective. We have contacted several accomplished game designers and game researchers to obtain their insights into issues in feedback in Games for Health Journal.
