This interface consists of textile electronic modules attached to a sleeping bag and a set of picture cards that can be fixed with Velcro. As children choose the elements they need and fix the picture cards, they ear the story being created. The cards are attached with Velcro (loop side) sewed with conductive fabric.
In the current prototype four textile modules are fastened to the sleeping bag’s surface through metal buttons. Each module has Velcro (hook side) conductive contacts connected to the Lily Pad Arduino. As each card is fixed to the modules, it closes the circuit on the base. The combination of the open and closed contacts identifies the card. The current prototype uses four contacts per card allowing 2^4 = 16 different cards. Each card has an audio file with a narrated voice for the respective picture sewed on it. In the current version the interface is connected to a computer for composing and playing back the audio narrative.
This work is funded by FEDER funds through the Operational Competitiveness Factors Program - COMPETE and by National Funds through the FCT – Portuguese Foundation for the Science and the Technology within the Project: PTDC/CPE-CED/110417/ 2009, Hybrid Learning Materials Project, and the Doctoral Grant: SFRH/BD/62531/2009.
The underlying concept of this project is the creation of innovative pedagogic materials that promote experimental, participatory and active involvement from an early age by bringing together the tradition of games and playful activities with the new interactive technological solutions. Our approach is to develop and evaluate a toolbox of Tangible Interfaces using low cost materials, such as paper and cardboard embedded with sensors.
