  virtual reality (VR). Gesture-based approach, one of the most commonly us
 ed approaches, enables bare-hand, eyes-free, and direct retrieval by using
  assigned gestures. However, it is difficult to retrieve an object from pl
 enty of objects accurately by using gestures due to the one-to-one mapping
  metaphor, the limitation of finger poses, and memory burdens. Previous wo
 rk has focused on gesture design, ignoring the context. In fact, there is 
 a consensus that objects and contexts are related. This indicates the obje
 ct expected to be retrieved is related to the context including the scene 
 and the objects users interact with. Therefore, we proposed a commonsense 
 knowledge-driven joint reasoning approach for object retrieval, where the 
 human grasping gesture and the context are modeled by an And-Or graph (AOG
 ). This approach enables users to accurately retrieve objects from plenty 
 of candidate objects by using natural grasping gestures according to their
  experience of grasping physical objects. The experimental results show th
 at our proposed model improves retrieval accuracy. Finally, we propose an 
 object retrieval system based on the proposed approach and two user studie
 s demonstrate that the system enables efficient object retrieval in virtua
 l environments.\n\nRegistration Category: Full Access, Enhanced Access, Tr
