Problems solved by technology
The movement and clicking of the mouse meet most of the needs of daily use of the computer. However, the mobile phone does not have such peripherals, and can only capture objects through the camera. It is relatively simple to realize the movement of the mouse, but in response to clicking the left button It is still difficult to input operations such as holding down the left button all the time

Embodiment Construction
[0021] The interaction method for responding to events based on feature image rotation in the present invention will be described in detail below in conjunction with the accompanying drawings.
[0022] Such as figure 1 As shown, the interaction method provided by the present invention to respond to events based on feature image rotation is based on such as figure 1 The compass pointer implementation shown, binds a compass pointer to the feature image, and the compass pointer includes a virtual point (ie figure 1 The ball in 2) and a virtual rod (ie figure 1 In the cylinder 1), the user rotates the object in reality, and the feature image of the object in virtual reality also rotates accordingly. The virtual point rotates with the feature image, and the rotation trajectory is as follows: figure 1 The dotted line in the middle shows a circle, the virtual rod does not rotate with the user's operation, but always faces the top of the screen, similar to a compass, the center of t...

The invention discloses an interaction method for event responding based on characteristic image rotation. The method comprises the steps that a virtual point and a virtual rod are bound for a characteristic image, wherein the virtual point is rotated synchronously with the characteristic image, the orientation of the virtual rod is kept unchanged and a rotation route of the virtual rod is intersected with a rotation route of the virtual point; and an event can be triggered when the characteristic image is rotated till the virtual point and the virtual rod are intersected or separated. The interaction method for the event responding based on the characteristic image rotation provided by the invention has the advantages that functions of a left button of a mouse are implemented by a compass pointer; and better interaction experience can be provided in comparison with a virtual button.
Description
technical field [0001] The invention relates to the field of virtual reality of computer science, in particular to an interaction method for responding to events based on feature image rotation. Background technique [0002] Virtual reality, referred to as VR (virtual reality), was proposed by Jaron Lanier, the founder of the American VPL company, in the early 1980s. After experiencing a complete failure in the 1990s, it once again appeared in the public eye. . Its specific connotation is: the comprehensive utilization of computer graphics system and various interface devices such as reality and control to provide immersive technology in an interactive three-dimensional environment generated on the computer. VR (Virtual Reality) technology can be widely used in many fields such as urban planning, interior design, industrial simulation, restoration of historical sites, bridge road design, real estate sales, tourism teaching, water conservancy and electricity, geological disa...
