This paper starts from the reality of the interior design industry, combines the characteristics and system of VR technology to elaborate in detail, starts from the interior design process, takes several projects interior design as an example, compares the traditional interior scheme design method with the interior scheme design method under VR technology, and summarizes the innovation of the VR technology in the interior scheme to the art design. Compared with the typical scheduling algorithms FCFS and SJF, the A* algorithm proposed in this paper has better execution efficiency, with the average response time and waiting time in the interval of 0~0.3 and 0~0.6, respectively. The user interaction related indexes have high scores, all of them are not less than 6 points. Comparing with two traditional interior design methods, the interior program design method under VR technology improves the overall visual effect of the interior space, with the overall visual effect exceeding 80% in both cases. It can also change the thinking and approach of traditional design to create a different emotional design of interior space.
