SayBooks is mobile app lets you link physical objects to digital contents via visual digital annotation and recognition. Record your contents and drop the contents on physical objects. Other users can access to the contents via visual recognition from SayBooks. On Museums and art galleries, both curators and visitors can generate digital contents (currently audio only) on paintings. In real-time, the contents can be shared other users. The same contents linked to the exhibitions are also accessible from the printed art books sold in the museum shops. Museums can take advantage of SayBooks to boost revenue by packaging digital contents with printed materials.
