a persuasive data visualization that maps a player’s daily foot step count to the growth & activity of an animated virtual character, a fish in a fish tank. the "Fish’n’Steps" application links the size of a fish as the step count, while success in reaching a participant’s daily goal affects its facial expression (e.g. happy, angry or sad). baby fish appear once the upper appearance level is reached.
some fish tanks also include other players’ fish, to create an environment of both cooperation & competition. in a 14-week study with 19 participants, the game served as a catalyst for promoting exercise & for improving game players’ attitudes towards physical activity.
