摘要：Implicit interaction based on context information is widely used and studied in the virtual scene.In context based human computer interaction, the meaning of action A is well defined. Forinstance, the right wave is defined turning paper or PPT in context B, And it mean volume up incontext C. However, Select object in a virtual scene with multiple objects, context information isnot fit. In view of this situation, this paper proposes using the least squares fitting curve beam topredict the user's trajectory, so as to determine what object the user’s wants to operate .Andfitting the starting position of the straight line according to the change of the discrete table. Andusing the bounding box size control the Z variable to move in an appropriate location.Experimental results show that the proposed in this paper based on bounding box size to controlthe Z variables get a good effect; by fitting the trajectory of a human hand, to predict the objectthat the subjects would like to operate. The correct rate is 88.6%.
