DEDOS-Editor is a tool designed to allow teachers to create educational activities in a simple and flexible manner, looking to leverage the design potential of the teaching community by empowering it to create, adapt and modify educational activities for traditional computers and novel multitouch displays, including collaborative tabletops. Once the educational project is created, students will solve the activities using DEDOS-Player. DEDOS-Player is in charge of adapting dynamically the activity layout to the number of the students using the device as well as of proving easy on-execution playing modes to adapt the single design to various educational scenarios.
