　　Abstract：The paper introduces a new experience platform which is based on the combination of the augmented reality technology，strapdown inertial navigating system and force-feedback technology. It builds an operational augmented-reality environment. On the hardware aspect，the platform uses the Intel Menlow embedded platform as the central data handling units and fully exerts its powerful ability to handle multimedia data. The platform contains a Force-back exoskeleton attached with local peripheral circuits which can collect and process the comprehensive data of the tester's hand. On the software aspect，the platform based on the strapdown navigation algorithm and the three-dimensional registration algorithm can effectively realize the feature including virtual assembly, and experience games or movable desktop with feeling of grip.Compared with some existing similar system，this system has the advantages of low cost，good experience and low power consumption. These advantages will lay a foundation for future implementation of portable augmented-reality embedded product.
