Embodiment 1

[0027] Before describing the specific embodiments of the present invention, several concepts are first introduced:

[0028] Flow calculus, a formal method proposed by Michael Thielscher in 1998 to describe the dynamically changing world and the action reasoning of intelligent agents: it is believed that any state change in the world can be regarded as the result of action. Flow calculus extends scenario calculus by introducing the concept of state. At the same time, it adopts the reasoning mechanism of Progression and uses the state update axiom to effectively solve the problem of representation and reasoning of frame problems.

[0029] Flow calculus has four basic concepts: flow (fluent), action (action), state (state), situation (situation), defined as type (sort). Flow (fluent) represents the atomic properties or states of objects in the physical world that change over time; state (state) represents a snapshot of the environment at a certain moment, which is synthesized by ...

Embodiment 2

[0108] Figure 4 A flow chart of a virtual human running method provided by the second embodiment of the present invention is shown, and the details are as follows.

[0109] Step S21, receiving a user instruction, analyzing the tasks contained therein according to the received user instruction, and obtaining a planning triplet corresponding to the task;

[0110] Preferably, the step S21 specifically includes:

[0111] receiving a user instruction, and decomposing the tasks contained in the received user instruction into at least one task sequence;

[0112] A planning triplet corresponding to the task sequence is determined, and the planning triplet is composed of a plan, a task, and a state corresponding to the task sequence.

[0113] Step S22, according to the planning triplet, determine the execution pair corresponding to the task, and execute the task according to the execution pair;

[0114] Preferably, the step S22 specifically includes:

Abstract

The invention is applicable to the field of virtual reality, and provides a virtual human and an operation method thereof. The virtual human comprises a planning unit, a behavior set, an executing unit, a state unit and a flow set, wherein the planning unit is used for resolving tasks contained in a user instruction according to the received user instruction; a planning triple corresponding to the task is obtained and is sent to the executing unit; the executing unit is connected with the behavior set and the state unit, is used for determining an executing two-tuples and executes the tasks; the behavior set is used for storing behaviors contained in the task; the flow set is used for storing flow contained by the virtual human; the state unit is used for providing the current state. The virtual human provided by the invention has the advantages that the current state of the located virtual environment can be actively sensed, so that the virtual human is like a real person in a real environment; the action to be implemented can be automatically decided according to the tasks to be executed.

Description

technical field [0001] The embodiments of the present invention belong to the field of virtual reality, and in particular relate to a virtual human and an operating method thereof. Background technique [0002] Virtual human can be divided into two types in terms of application functions, one is digital virtual human or data virtual human, which is mainly used for the research of human biological characteristics; the other is intelligent virtual human, which is mainly for the simulation and simulation of human intelligence. Simulation research is a major application branch of artificial intelligence, used for the design of virtual images or virtual characters, and has a wide range of applications in cultural and creative works, virtual exercises and computer simulation systems. [0003] Bowman et al. proposed the concept of semantic objects in IRVEs. Semantic objects refer to those objects or objects that users can perceive in the virtual scene that can respond and give feed...
