Classroom Project

Junior Kindergarten (JK) students at Kennedy-Longfellow school solved the mystery of the missing gingerbread cookies with some help from an augmented reality iPad app called Layar. JK teacher Siobhan Patterson developed the interactive scavenger hunt, based on the Gingerbread Man book, which included gingerbread cookie paper cut outs placed with different staff throughout the school. Audio clues were prerecorded on the computer using Garageband and pitched up to mask the teacher’s voice, as well as sound more “gingerbready.” The recorded clues were cued by holding the iPad in front of each gingerbread cut out with the Layar app interface open. When the Layar app recognized the image, it triggered an overlay of an audio recording (it could be video, image — or whatever you want) and the students pressed the play button to hear the clue.

Once the group solved each of the clue “riddles” they were excitedly off to the next location! Ms. Patterson found that it helped to hold up the iPad as close as possible as well as make sure there was enough light for the Layar app to recognize the trigger images. Teachers at KLO are excited about the possibilities with Layar, especially experimenting with using it to support language acquisition.
