Remote Joint Shopping System is a remote communication prototype for a joint shopping scenario in which the communication always involves the environment and objects. This system is to offer a sensation shared by the two geographically separated users that they are co-located together going for a shopping in the same world. Although it might require varieties of aspects to fully realize such sensation, in this prototype we intendto support users to accomplish a shopping task together with help of gestural interaction so as to make users feel a close connection and aware a certain extent of togetherness. In this paper, we introduce our user study and analysis of the Remote Joint Shopping System. The major purpose of this study is to investigate the human-to-human interaction between users and test whether this system could assist the remote collaboration.
