An existing travel application for Android devices has been adapted in order to incorporate educational elements with online interactive material. The case study concerned the ancient market of the island of Thassos. For this purpose, a website has been developed where users can upload their educational material about the various artifacts and monuments in the ancient market. When on site, visitors can use the Android application to scan the QR codes that accompany the artifacts, and view the corresponding uploaded material on their device. The application was developed in Eclipse using the Android SDK and the open source ZXing library.
