Transcript of Alien Health: An Embodied Exer-game with Nutrition
Genesis of an Active Nutrition Game:Alien Health
Mina C. JohnsonRadboud Universiteit and
Why?• Obesity epidemic is still ongoing
• Creating videogames to change behavior seems a timely way to meet children where they are (enough with the pamphlets...)
• In addition, when a game is co-designed for parents to play with - there is a chance for real change
• Alien Health is in demo area
First iteration Mixed Reality
12 IR motion capture cameras
Using handheld trackables to move virtual objects
SMALLab
Situated Multimedia Arts Learning Lab
Chemistry Titration – in a virtual flask
SMALLab at Arizona State University
Excellent embodied environment for multiple users
How does using the whole body (gesture) affect learning and retention?
Multiple studies have shown effects of better learning in
• Math• Geology• Physics

SMALLab Centripetal Force Study (under review)
Significant interaction between embodiment and time, generative test items

How to instruct in nutrition in an engaging manner using the whole body?

Alien Health: Mixed Reality PilotStudy with one class of 9 year-olds, one exposure to game
DV = paper/pencil nutrition knowledge test
Significant gain paired t-test, t(18) = 4.13, p <.001.
Next Iteration• Needed to move to more cost effective platform
• Really focus on message – What is the nutrient profile in common
foods? Make that info “pop”
• Give practice so food decisions become more automatized

Alien Health with Kinect Beta 1
Experimental Condition – Foundling Alien narrative and exercise
Control Condition - same forced choice content, performative aspects
Included level with nonfoods
For exercise condition, quality and duration of short exercises assessed via Kinect
Experimental: Physically performed exercises to help alien metabolize food
Control: Game-like tap moving dots and observe stick figure exercise
Again, we see group-wise retention effects with delay

Pretest Posttest 2 Week Followup
Johnson-Glenberg, Henry, & Savio-Ramos, 2014. Games for Health Journal. Open Access.
In education, we are in the business of retention
More knowledge retained at followup in condition with embodiment and more exercise
Being active during learning helps maintain knowledge in several content domains
Similar results seen in skill acquisition and memory consolidation literature (Stickgold & Walker, 2007)
What’s better than a make over?
A second make over!!
Increasing knowledge is well and fineBut what about behavioural change?
Next iteration = Kinect V2 in classrooms, Feb 2016
Translate to nederlands and adding typical foods like:krentenbol vs. volkoren broodje
More DV’s like real food choice - snack task
Four classes of 6th graders, class randomly assigned to Control = BAUAlien Health = Kinect V2
More platforms:Intel’s RealSense with embedded sensors
and Virtual Reality - now that it is “ready for its close up”
With RealSense able to pilot the “runner” spaceship by leaning
Note: Your ship must have enough fuel aka proper nutrition!
Intergenerational gameplay, etc.• Always thinking about designing socially and
getting players to discourse – we need to get the food purchasers in on the gameplay
• How to make attractive to parents, homework
• Enter own food items
• Get in grocery stores so kids can play while the parents shop...
Look forward to reporting back on progress next year.
Thank You!
