LEGS system in a zoo

In the LEGS system, GPS-equipped mobile phones are used to learn about animals and their bodies from the viewpoint of evolution in a zoo. This system identifies nearby animals, asks questions about the animals' bodies to enhance observation, provides navigations for the next observations, and summarizes several observed animals' parts from the viewpoint of evolution. 24 students (age: 14--15 years old) learnt about animals using the mobile phones in a zoo. We evaluated the system and found that it helped students explore, observe, and learn about animals' bodies independently in the zoo.
