　　摘要：本文介紹了一個結合增強現實、慣性導航和力反饋技術的體驗平臺。該平臺在功能上以實現人手的握力感為基礎，構建了一個可操作的增強現實環境。在硬件上，本平臺充分利用基于Intel(R) Atom(TM) 處理器的嵌入式平臺的多媒體處理能力，將其作為數據處理的核心單元，配合為此平臺專門研制的具備全方位數據采集功能的外骨骼式力反饋機構和局部外圍電路，保障了平臺穩定流暢的運行;在軟件上，以捷聯導航系統算法、基于視覺的三維空間注冊算法等為基礎，高效地實現了虛擬裝配、體感游戲和具有觸感桌面應用等功能。相比市面上現有的類似系統，具有成本低、用戶體驗性好、功耗低等優點，為將來實現消費級的可移動增強現實系統鋪墊了一定基礎。

　　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.
