Abstract-In this paper we present an intuitive interaction technique for everyday objects. We propose a system that allows the user to interact with everyday objects, and use them to make smart scenarios. We enrich the objects with a portable projected interface that is supported by 3D accelerometer in order to build novel user object interaction scenarios. Moreover, we present double crossing as an interaction technique for manipulating finger interface. We conducted experiment to test the applicability of the proposed system with different applications. Our results showed that the proposed system has a lot of potentials to enrich different domains of applications like object data storage, education Montessori cubes and smart shopping goods.Index Terms-Object gestures, handheld projector, ubiquitous environments and portable interface interaction.
