Using our scenarios, we conducted 4 concept validation sessions. We compiled our results into groups based on related issues, as found in our sessions.

• Goal Setting and Measurement
• Privacy and Encouragement
• Family Status
• Reminders and Control
• Activity Suggestions
• Rewards

These results are detailed below. Regarding location and privacy, we found that the refrigerator door was appropriate for public displays of information, while locations such as the bedroom are appropriate for private and more detailed displays of individual information.

Main Design Takeaways

Goals and progress should only visible to adults.
Activity suggestions need to empower, while not intruding upon lives.
Facilitate communication of encouragement and loose activity plan.

Concept Validation Participants

Family with 5 kids: 4, 7, 11, 14, 17 years old
Family with 2 kids: 21, 25 years old
Family with 2 kids: 20 months, 5 years old
Family with 4 kids: 2 weeks, 6, 9, 12 years old

Concept Validation Results

Goal Setting and Measurement

• Parents individually want to set goals and keep track of their own progress
• Kids don't need explicit health goals and measurement of progress (they need play)
• Parents do have goals for their children, but they are not the children’s goals
• Long term trends are more informative than detailed daily statistics
  

Privacy and Encouragement

• Only show enough information to enable other (adult) family members to give encouragement
• Detailed health information needs to be individual
• What health information is shared depends on the kind of relationship between adults, and between parent to child
  

Family Status

• “If you don't know your kid's current status, what kind of parent are you?”
• A reflective status of long term health effects of their children is more beneficial for parents
• Children do not need to know the activity status of anyone in their family, especially not themselves
  

Reminders and Control

• Adults choose to have lazy days, and do not need to be reminded about their activity level then
• Do not impose activities upon household that the parents have not chosen
• It is the parent's role to remind kids to be active
  

Activity Suggestions

• Providing children suggestions is a good, as long as they are approved by the parents beforehand
• Suggested weather and time appropriate activities empowers parents and gives them choices
• Communication of loose activity plans helps family members plan for the day
• Getting kids involved in family activity decisions
• Maintain fairness in family activity choices

Rewards

• Communication of compliments from family members is good
• Compliments from the agent are potentially weird, and should be restricted to an objective display of progress towards a goal
