Geography virtual emulated three-dimensional mouse pen in actual space

Abstract

The invention discloses a geography virtual emulated three-dimensional mouse pen in an actual space. The pen consists of a pen tip part, a pen holder part, a device part and a prism body, wherein the pen tip consists of an LED (light-emitting diode) lamp pen tip connected with a control key; the pen holder part is provided with a control unit, a power module and the control key; the power module is connected with the control unit; the device part close to the tail end is provided with an inclination sensor and a wireless receiving and transmitting device; and the prism body is arranged at the most tail end. A human-computer interaction method comprises the step that a user interacts with a geographical virtual system in the actual space through vision and a command button interacting passage, and the aim of human-computer interaction is fulfilled. The three-dimensional mouse pen is applied in the geographical virtual system in the actual space, so that the user can interact with the geographical virtual environment in a more actual, direct and effective way, the interaction and the immersion feeling are greatly enhanced, and the human-computer interaction way in which the geographical virtual environment scene can be more directly and generally operated in the actual space is provided to the user.

[0002] The research on 3D terrain modeling and its visualization is one of the most dynamic directions in the field of geoscience information technology. In recent years, the research on geographic virtual simulation technology has been extensive at home and abroad. Among them, the human-computer interaction function of the operating system is the most A very important part of the geographic virtual simulation system is also an important factor that determines the operability of the geographic virtual simulation system. Especially in recent years, the development of real space 3D visualization technology enables users to integrate into the geographic virtual simulation system personally. Increased user immersion; however, most of the existing 3D visualization systems mainly use traditional interactive methods such as keyboards, mice, and various pattern recognition devices, which are cumbersome and unintuitive to operate, and cannot realize geographic virtual simulation scenes in real space reproduction operations; for example, when the object being processed is a traditional two-dimensional model, the two-dimensional movement of the interactive device (mouse) cursor can be mapped to the two-dimensional model one by one, so that almost all required operations can be realized conveniently; however, When in the geographic virtual simulation system of real space, the object of concern during interaction becomes a three-dimensional geographic model, because the image point (x, y) on the computer screen is different from the three-dimensional coordinates (x, y, z) of the real space. Having a unique corresponding relationship greatly increases the difficulty of the interactive operation, and the traditional interactive method can no longer satisfy the reproduction operation of the geographic virtual simulation scene in the real space
