Self-Correcting Algorithm Based on Divided Process

In the gesture interaction, the operator can withdraw the operation which is the misoperation of the operator by self correction to realize the better interaction of human and computer. This paper presents a new self-correcting algorithm, firstly divide the process of gesture interaction into sub processes, and set up the scene information database and gesture state information database, secondly, the gesture state information and the scene information of the start time of the sub process are stored in the corresponding information base, and establish the gesture state information timing table and the scene information timing table, finally achieve the fallback operation by visiting the gesture state timing information table and the scene information timing table. The innovation of this paper is not only to create the scene information database and gesture state information database to avoid redundant information of the scene information and gesture state information, but also to divide the interaction process into sub-processes, which allows the operator rollback with the interval of the sub-process to ensure the integrity of the operation in self correction process. The experimental results show that, the algorithm described in this paper not only reduces the time cost of self correction, but also allows users to operate with more comfort and enjoyment.
