An Educational Game to Teach Children about Air Quality Using Augmented Reality and Tangible Interaction with Sensors

Area of Science:

• Environmental Health Science
• Human-Computer Interaction
• Educational Technology

Background:

• Air pollution poses significant risks to respiratory health and can cause premature death.
• Indoor air quality is a critical concern, especially for children whose developing organs are more vulnerable.
• Existing methods for educating children about air pollution lack engaging and interactive elements.

Purpose of the Study:

• To design, implement, and validate an augmented reality (AR) game for children to learn about indoor air quality.
• To raise children's awareness of air pollution through interactive and playful experiences.
• To make invisible air pollutants tangible and understandable for young learners.

Main Methods:

• Developed an AR game that visualizes real-time air pollutant data from physical sensor nodes.
• Incorporated causal learning by having children interact with real-life objects (e.g., candles) and the sensor.
• Evaluated the game's effectiveness and usability with 27 children (ages 7-11) using the Wizard of Oz method.

Main Results:

• The AR game significantly improved children's knowledge of indoor air pollution.
• Children perceived the game as easy to use and a valuable learning tool.
• Participants expressed a desire to continue using the game in various educational settings.

Conclusions:

• Augmented reality games can be effective tools for educating children about complex environmental health issues like air pollution.
• Tangible and interactive learning experiences enhance knowledge acquisition and engagement in young learners.
• The developed AR game demonstrates potential for broader application in environmental education.
