EXERGAMES !

Most experiences are “gamifying”

Points, tokens, badges as feedback

EXERGAMES !

Wii-fit Usage over three months decreased for eight families

No significant health change

Owens, S. G., et al. 2011. Changes over three months…

EXERGAMES !

Exergames may be a gateway…

Either towards vigorous exercise or other games

PRIMING !

Priming is the visual, audio, or other sensory cues that provide a subtle shift in attitude, believes or behavior. Prior work has shown explicit intention has an impact on behavior and sustained engagement.

HYPOTHESES !

Exercise:

More intense; shorter ; decreased positive affect

Gaming: Less intense; longer; increased positive affect

Feedback

“TELL US ABOUT YOUR SESSION” !

“I played through many songs […] I really liked and had a lot of fun. I found myself becoming very competitive, more than I had imagined I would [because I do not play a lot of games]." <M, G×nH>

2014/4/29 @frankc 40

“TELL US ABOUT YOUR SESSION” !

“This could be one of the things I do to train. What you see a lot on dance teams is it’s difficult to learn new routines due to lack of feedback on what I’m actually doing…” <F, E×nH>

2014/4/29 @frankc 41

DUAL BENEFITS !

“I think this is a great game. I typically run and do strength training and burn about 360 calories at the gym per session. You could have used a different game… It’s still not as efficient as a workout at the gym.” <M, E×nH>

•  Eight in exercise priming; three in gaming priming

2014/4/29 @frankc 42

“GAMIFICATION” !HEALTH FEEDBACK IN EXERGAMES !

No participants mentioned health feedback as particularly insightful or motivating “I did not use the feedback […] I play sports. I don’t run or lift weights. Exercise is boring, rather than doing something monotonous I like to play games.” <F, E×H>

2014/4/29 @frankc 43

ADDED BENEFIT !WITH PRIOR EXPERIENCE!

Excellent as learning cues “This could be one of the things I do to train. What you see a lot on dance teams it’s difficult to learn new routines due to the lack of feedback on what I’m actually doing.” <F, E×nH>

2014/4/29 @frankc 44

RESULTS !

Exertion = 4.5 MET ~ MVPA We saw no significant effect on RPE, EE, or PA

2014/4/29 @frankc 45

LIMITATIONS !

Single session

70.4% of our participants reported regular activity ��48.4% for the rest of the US

HEALTHIFICATION!

Gamification is not enough without embedding this activity deeply in the activity. Cannot be “bolted on” Healthifying = Emphasizing dual benefits of the activity so it's more engaging to the individual

2014/4/29 @frankc 47

“HEALTHIFYING” EXERGAMES !

@frankc

Intentional priming emphasized the dual purpose of Dance Central Framed a strong game as exercise and increased duration of use by 25% Gamification might be too blunt of an instrument. Psychology offers a rich set of tools and principles that lead to long-term healthful impact.
