Summary

Method is used to evaluate children's experience in outdoor pervasive gaming.

Description

While playing the game, video is recorded. Afterwards the video is analyzed for physical activity, social interaction and focus (what are the children looking at). These objective results can be combined with subjective opinions of children gathered during interviews.

Strengths

Objective measure of how much social interaction takes place. Doesn't interfere during game play.

Weaknesses

Coding of videos is very time consuming.
