Physical activity among children declining
The study focused on more than 300 children and their parents enrolled in after-school programs with the YMCA of Metropolitan Atlanta. Half were assigned to the mixed reality kiosk while the rest used a computer program for setting exercise goals without social feedback.

The digital fitness program used a virtual dog designed by the research team to help children understand how to set physical activity goals and to encourage them to reach the goals they set. Fitbits tracked the activity of each child. If they reached their goal, they were able to play with the dog.
