Abstract
Various studies on latency in remote mixed reality collaborations (remote MR collaboration) have been conducted, but studies related to interaction latency are scarce. Interaction latency in a remote MR collaboration occurs because action detection (such as contact or collision) between a human and a virtual object is required for finding the interaction performed. Therefore, in this paper, we propose a method based on interaction prediction to reduce the time for detecting the action between humans and virtual objects. The proposed method predicts an interaction based on consecutive joint angles. To examine the effectiveness of the proposed method, an experiment was conducted and the results were given. From the experimental results, it was confirmed that the proposed method could reduce the interaction latency compared to the one obtained by conventional methods.

Summary
Interaction latency in a remote MR collaboration occurs because action detection (such as contact or collision) between a human and a virtual object is required for finding the interaction performed. As latency affects the usability (e.g., interaction satisfaction) as well as the efficiency of remote MR collaborations, it is necessary to reduce it Due to this need, various studies have been conducted to improve the latency. Conventional studies have focused on reducing latency between the moment of performing the interaction and delivering the performed interaction information Action detection, such as contact between a human and an object, is required to find the performed interaction in a remote MR collaboration. Defining the time to check whether the interaction is performed according to the user’s intention in a remote MR collaboration as the interaction latency, conventional solutions have limitations because it is difficult to reduce latency
