Description
Technical Field
The invention relates to the technical field of game interaction, in particular to a game interaction method aiming at a visual impairment crowd Wen Nong traveling virtual scene high-order demand.
Background
With the economic development and the steady growth of the living standard of people, the entertainment modes of masses are continuously changed, and the game interaction becomes a part of the entertainment life of masses. Most of the current entertainment life of games is developed for normal people with sound bodies, and games for visually impaired people hardly exist, particularly games meeting the requirements of improving the life quality of visually impaired people. According to the Marlo demand hierarchy theory, once a certain hierarchy of demands is satisfied, people seek the next hierarchy of demands. Visually impaired persons are also satisfied with just a hierarchy of physiological needs, as are higher-order needs, including social needs, self-esteem needs (e.g., sense of achievement, independence, reputation, esteem, etc.), and self-achievement needs. But currently, such infrastructure and access is often lacking or only partially available to visually impaired people in real life. For example, there is also a strong social demand for visually impaired people, but because of physical defects of the people themselves, the number of social circles that can be seen in the real world is often very limited, resulting in unsatisfied social demands. Also, in the case where the design requirement is hardly satisfied, the self-esteem requirement and the self-realization requirement are often difficult to obtain because of the difficulty in obtaining feedback ideas of others.
In the game of the virtual world, most of the current games are developed for the common crowd (namely, body is sound), so that the visually impaired crowd often hardly participates in the games, and the participation, enjoyment and enthusiasm of the visually impaired crowd are reduced. Like the game developed for the ordinary crowd here, because the vision-impaired person can not see, the interaction generated under a plurality of operations is inconvenient to carry out, and a plurality of target objects are often involved in the virtual scene of the jockey and the travel of the game, wherein the target objects comprise virtual objects and virtual roles, different virtual objects or virtual roles in different scenes need to play corresponding audio, the unreasonable binding of the audio and the target objects can bring about the need of the vision-impaired person to manually operate to play correct audio, and the interaction operation of the vision-impaired crowd is increased and inconvenience is brought. The above is only one situation of inconvenience brought to the visually impaired people in the existing games, and the current games are generally inconvenient for the visually impaired people to participate.

step 3: if the absolute value of the difference between the average curvature of the current real walking path and the average curvature of the virtual walking path is smaller than a preset threshold value, recommending a plurality of target objects in front of the virtual walking path in the current Wen Nong travel virtual scene according to the traveling direction so as to guide a user to search for the target objects;
Step 4: the game picture configuration file can be loaded with the audio configuration file, the triggering configuration file is used for loading the audio configuration file according to preset triggering conditions, at least one audio unit in the audio configuration file is triggered, dynamic loading of the audio configuration file can be achieved through adjusting the triggering conditions, and accordingly the aim object can be updated and played dynamically in the Wen Nong virtual scene.

Further, in step 1, the two interactive game versions are respectively an explored version and a relaxed version, the explored version aims at providing a user to explore different areas and different target objects in the initial Wen Nong travel virtual scene, the user is guided to find Wen Nong different areas and different target objects of the travel virtual scene through a task form, and to interact with the target objects,
The purpose of the relaxed version is to provide the user with a experience in the initial Wen Nong travel virtual scene, to directly and arbitrarily navigate the desired area and target object within the initial Wen Nong travel virtual scene through the tour path, and to interact directly with the target object,
each version of the Wen Nong travel virtual scene is appropriately added and/or deleted and/or hidden and/or modified to paths and/or regions and/or target objects based on the initial Wen Nong travel virtual scene.
Further, in step 2, only the curve segments of the real and virtual walk paths with the average curvature exceeding the preset threshold value count the curve segment sets with the same bending direction, and the curve segments with the average curvature not exceeding the preset threshold value prohibit the statistics to the curve segment sets with the same bending direction, so as to avoid that only the curve segments with small path direction change are regarded as the path direction change.
Further, calculating the average curvature of the curve segments in the curve segment set with the same bending direction comprises the following steps:
step S1: dividing the curve sections into k sub-curve sections according to the curve bending direction, marking the original curve sections before division as integral curve sections, wherein k is more than or equal to 2, and marking the sub-curve sections where at least one of the k sub-curve sections changes in the bending direction and the bending direction is suddenly changed as suddenly changed sub-curve sections;
Step S2: for the non-abrupt sub-curve segment, discretizing W discrete points of the non-abrupt sub-curve segment, and fitting a curve function expression of the current non-abrupt sub-curve segment according to the W discrete pointsThe curvature of each curve point in the W discrete points of the non-abrupt sub-curve segment is calculated according to the formula (2), and then the average value of the W discrete points is calculated as the average curvature q of the current non-abrupt sub-curve segment, wherein the formula (2) is as follows:

the curvature of each curve point in W discrete points on each non-abrupt sub-curve segment can be calculated according to the formula (2), so that the average value obtained by carrying out arithmetic average on the W discrete points is the average curvature of the corresponding non-abrupt sub-curve segment;
for non-abrupt sub-curve segments, the curve function expression is fittedThe gentle condition of the walking direction can be reflected better, and the curve function expression is directly used for ++>The average curvature of each point curvature is calculated to reflect the actual condition of a small section of gentle walk path, and for the abrupt sub-curve section, the average curvature c of the abrupt sub-curve section is calculated according to a formula (3):

Further, when the vision-impaired person is within a preset threshold value based on the difference between the average curvatures of the real and virtual walking paths and the number of the explored target objects exceeds the preset threshold value, game rewards are carried out to the vision-impaired person so as to encourage the vision-impaired person to explore more scenes and target objects in the Wen Nong travel virtual scenes, and when the game rewards obtained by the vision-impaired person exceed a certain preset number, a new virtual path and a new target object are unlocked so as to better encourage the vision-impaired user to explore,
The game rewards are one or more music pieces of background music corresponding to one or more target objects in front of the current path, and the background music can be successfully played after the obtained application pieces reach the number of one complete background music.
Further, classifying all target objects in the Wen Nong travel virtual scene, dividing the target objects into two major categories, namely virtual roles and virtual objects, carrying out hierarchical division on the virtual roles and the virtual objects layer by layer, wherein the lower hierarchy is finer and more specific in unit number, and the corresponding unit number is smaller.
Further, the triggering condition is that condition one and/or condition two are satisfied:
condition one: the average curvature of curve sections with abrupt changes in the bending direction in the current real walking path or the virtual walking path for the first time is more than or equal to a preset threshold value, and the average curvature of all curve sections with abrupt changes in the residual bending direction in the current real walking path or the virtual walking path is less than the preset threshold value;
condition II: in the switching of the current virtual travel path to the next virtual travel path, namely in the joint of the end point of the current virtual travel path and the start point of the next virtual travel path, judging that any classification target object under any level exists in the next virtual travel path is larger than the corresponding classification target object under the corresponding level of the current virtual travel path,
And when the first condition or the second condition is met, re-binding the target object on the current virtual walking path meeting the first condition or the second condition and the target object which can be reached by the virtual walking path according to the audio configuration information.
And when the first condition and the second condition are met, all target objects in the virtual scene or target objects on a plurality of virtual travel paths and the target objects which can be reached are rebinding Wen Nong according to the audio configuration information.
Further, when the vision-impaired person browses a new target object in the Wen Nong travel virtual scene, voice is adopted to leave and praise the target object, and the messages and praise are displayed in the Wen Nong travel virtual scene by default or are displayed under certain conditions, so that the follow-up browsing of the target object can praise the messages of the vision-impaired person and carry out new messages, communication with other vision-impaired persons can be conveniently carried out, and social demands among the vision-impaired persons are met.
The beneficial effects of the invention are as follows: the invention can well realize exploration in Wen Nong travel virtual scenes based on comparison of the travel of the user (namely, the visually impaired crowd) in reality and the travel of the user in Wen Nong travel virtual scenes, and meets the requirements of the user on different levels including achievement sense, self-confidence, social contact and the like in the exploration process, thereby improving the participation comfort and enjoyment of the visually impaired crowd. Meanwhile, in the Wen Nong travel virtual scene, batch audio binding to the target object can be performed through the audio configuration file, so that the binding operation amount is reduced, and the audio production efficiency of the Wen Nong travel virtual scene is improved.

Detailed Description
The invention will be further described with reference to the accompanying drawings and detailed description:
as shown in fig. 1-3, a method for interaction of a virtual scene high-order demand game for a group of viewers Wen Nong, comprising the steps of:
step 1: an initial Wen Nong travel virtual scene is generated in advance, a target object and a path are arranged in the initial Wen Nong travel virtual scene, the path extends to different areas of the initial Wen Nong travel virtual scene, the target object is arranged on the path and the area to which the path extends, and the target object comprises a virtual character and a virtual object.
Based on the history record of the user or the currently entered user information, at least more than two play interactive versions are provided, and a user selection version instruction is received to enter a Wen Nong travel virtual scene under the corresponding version. The two interactive game versions are respectively an exploration version and a relaxation version, and the purpose of the exploration version is to provide a user to explore different areas and different target objects in the initial Wen Nong travel virtual scene, guide the user to find Wen Nong the different areas and different target objects of the travel virtual scene through a task form and interact with the target objects. The purpose of the relaxed version is to provide a user experience within the initial Wen Nong travel virtual scene, to be able to directly and arbitrarily navigate the desired area and target object within the initial Wen Nong travel virtual scene via the tour path, and to be able to interact directly with the target object.
Wherein, the Wen Nong travel virtual scene refers to a virtual scene formed by a travel and/or a agriculture travel, the travel generally refers to the play of cultural attributes, and the agriculture travel generally refers to the play of agriculture attributes. For example, for game interactions under a cultural tour theme park, a real cultural tour theme park or a purely fictional cultural tour theme park is simulated in the virtual scenario. Virtual scenes of the agricultural travel are also similar and are not described in detail herein. Therefore, the Wen Nong travel virtual scene (or simply called the un-travel virtual scene) can be a pure travel virtual scene, or can be a pure agricultural travel virtual scene or a virtual scene combining together, and does not refer to two virtual scenes which need to be switched to play.
Each version of the Wen Nong travel virtual scene is appropriately added and/or deleted and/or hidden and/or modified to paths and/or regions and/or target objects based on the initial Wen Nong travel virtual scene. For example, the explorer version adds additional paths and regions on the basis of the initial Wen Nong travel virtual scene, and adds target objects on the newly added paths and regions so as to be able to explore more content, enhancing the user's exploration desire. The relaxed version may delete or hide the relevant path and region and the target object on the deleted or hidden path and region in the initial scene, deleting meaning that the target is not available at all in the relaxed version of the Wen Nong travel virtual scene and cannot be restored, hiding meaning that the target is only present in the Wen Nong travel virtual scene if certain conditions are met (e.g., exact clicks).
Wherein, the visually impaired user refers to a situation that vision is wrong so as to be completely or insufficiently experienced by a crowd with normal vision to play the game based on the terminal, but relevant operations on the game on the terminal can be realized through voice recognition and/or through manual or foot-operated pressing, clicking and other operations, for example, a virtual character can be selected by listening to the voice or touching and clicking the corresponding position to talk with the virtual character. Since the implementation of user operations by the terminal does not belong to the improvement point of the present application on the one hand, but on the other hand it can be implemented based on the prior art, it is not repeated here how such a terminal is assembled.
Step 2: after the user enters the corresponding play interaction version, based on the real position of the terminal used for running the initial Wen Nong travel virtual scene held by the user and the virtual position of the user in the Wen Nong travel virtual scene of the play interaction version, the real user position represents the position of the user in the real world, and the virtual position represents the position of the user in the Wen Nong travel virtual scene, so that the real travel path of the user in the synchronization process of the virtual scene of the venturi and the venturi serving as the game can be constructed based on the real position, and the virtual travel path of the user in the Wen Nong travel virtual scene is constructed based on the virtual position. The walk path is a set of path length and path direction from the initial position to the current position, the real walk path is a set of path length and path direction from the initial position to the current position in the real position, and the virtual walk path is a set of path length and path direction from the initial virtual position to the current virtual position in the initial Wen Nong travel virtual scene. The travel path may be updated in real-time based on the progress situation and a curve may be used to fit the representation of the travel path or a segment of the travel path. And whether the same travel path is the same or not can be distinguished through the identification, for example, a plurality of virtual travel paths exist in a Wen Nong travel virtual scene, two adjacent travel paths are communicated or not, the two adjacent travel paths are communicated, the two adjacent travel paths can directly reach another virtual travel path from the current virtual travel path, and the other virtual travel path cannot be reached.
Calculating the matching degree A of the real travel path and the virtual travel path according to the formula (1):
------①
in the method, in the process of the invention,representing the average curvature of the ith curve segment in the real walk path, representing the change degree of the direction of the user walking in reality, wherein the change degree of the direction is converted from the current direction to the other direction, the larger the average curvature is, the larger the change direction of the user is, and the longer the duration is, and the smaller the change direction of the user is (i.e. the difference from the original walking direction is not large) and the shorter the duration is. />Representing the average curvature of the ith curve segment in the virtual walk path, representing the degree of change of direction of the user walking in the Wen Nong travel virtual scene from the current direction to another direction, the larger the average curvature represents the larger the user changes direction and the longer the duration, and conversely, the smaller the user changes direction (i.e. does not differ much from the original walking direction) and the shorter the duration. The matching degree a represents the consistency of the real travel path and the virtual travel path, and the larger a represents the larger difference between the real travel path and the virtual travel path, otherwise, the more the real travel path and the virtual travel path are converged, namely, the paths of the real travel path and the virtual travel path are the same, and when a=0, the paths of the real travel path and the virtual travel path are the same.
In the step, the consistency of virtual walking under the operation in the virtual scene of actual walking and Wen Nong traveling of the visually impaired people can be shown by calculating A, so that the visually impaired people can be induced to arrive at the actual target position in the actual scene based on the virtual walking path in a certain actual scene, the rapid and efficient arrival of the target position under walking is realized, and the honour sense and achievement sense of the visually impaired people are provided from the angle of successfully arriving at the destination end.
Referring to fig. 2 and 3, fig. 2 is a schematic diagram of a real travel path having q curve segments in total, and fig. 3 is a schematic diagram of a virtual travel path having m curve segments in total, n being smaller than q and n being smaller than m. The ith curve segment refers to an ith curve segment in a curve segment set with the same bending direction in a real walking path and a virtual walking path in the advancing direction. For example, in fig. 2 and 3, it is assumed that the real travel path has 10 curve segments, i.e., q=10, and the virtual travel path has 8 curve segments, i.e., m=8. However, since the 1 st curve segment in the real walk path and the 1 st curve segment in the virtual walk path have different bending directions and are identical to the bending directions of the 2 nd curve segments in the virtual walk path, the 1 st curve segment in the real walk path and the 2 nd curve segment in the virtual walk path constitute the 1 st curve segment in the set of curve segments having identical bending directions, and based on this, the curve segments in the bending directions in the real walk path and the virtual walk path are sequentially compared in the advancing direction, and the obtained curve segment having identical bending directions in the i-th curve segment is sequentially compared as the i-th curve segment.
In an alternative embodiment, only the curve segments of the real walking path and the virtual walking path with the average curvature exceeding the preset threshold value may count the curve segment sets with the same bending direction, and the curve segments with the average curvature not exceeding the preset threshold value are not counted in the curve segment sets with the same bending direction, so as to avoid that only the curve segments with small changes of the path direction are regarded as changing the path direction, and the small changes of the path direction are caused by the careless or unexpected movement of the user in the step direction, so that the curve segments need to be excluded.
Calculating the average curvature of the curve segments in the curve segment set with the same bending direction comprises the following steps:
step S1: dividing the curve sections into k sub-curve sections according to the curve bending direction, recording the original curve sections before division as integral curve sections, wherein k is more than or equal to 2, and recording the sub-curve sections where at least one of the k sub-curve sections changes in bending direction, namely the bending direction changes suddenly, namely the sub-curve sections where the bending direction changes suddenly, as abrupt sub-curve sections. For example, in fig. 2, at least one sub-curve segment spans the vertex of the 3 rd curve segment, that is, at least one curve point is located on each of the left and right sides of the vertex of the 3 rd curve segment, or by determining that the tangential direction of the immediately preceding curve point and the tangential direction of the immediately following curve point of the current curve point are changed, the curve segment where the current curve point is located is the curve where the mutation occurs in the bending direction.
Step S2: for the non-abrupt sub-curve segment, discretizing W discrete points of the non-abrupt sub-curve segment, and fitting a curve function expression of the current non-abrupt sub-curve segment according to the W discrete pointsThe curvature of each curve point in the W discrete points of the non-abrupt sub-curve segment is calculated according to the formula (2), and then the average value of the W discrete points is calculated as the average curvature q of the current non-abrupt sub-curve segment, wherein the formula (2) is as follows:
------②
in the method, in the process of the invention,representation of the Curve function expression +.>Second derivative of>Representation of the Curve function expression +.>Is a first derivative of (a). The curvature of each of the W discrete points on each non-abrupt sub-curve segment can be calculated according to the formula (2), so that the W discrete points are arithmetically averaged to obtainThe average value of (a) is the average curvature of the corresponding non-abrupt sub-curve segment.
For non-abrupt sub-curve segments, meaning that the user's corresponding path of travel at the curve segment is relatively gentle, without large directional changes, small directional changes may be considered as no changes, e.g., less than a threshold, and thus by fitting to its curve function expressionThe gentle condition of the walking direction can be reflected better, and the curve function expression is directly used for ++ >The average curvature of each point curvature obtained through calculation can better reflect the actual condition of a small section of gentle walk path.
For the abrupt sub-curve segment, the average curvature c of the abrupt sub-curve segment is calculated according to formula (3):
------③
in the method, in the process of the invention,representing the angular change from the starting point to the ending point of the current abrupt sub-curve segment, i.e. the angle between the respective tangents of the starting point and the ending point, < >>The arc length of the current mutant-curve (i.e., the length of the current mutant-curve) is represented. For the ith mutant sub-curve segment, only the corresponding +.>And->And substituting the curve into the formula (3) to calculate the average curvature of each abrupt sub-curve segment.
Therefore, for the ith curve segment in the global curve segments, the ith curve segment is calculated according to the formula (2) if the ith curve segment is a non-abrupt sub-curve segment, and the ith curve segment is calculated according to the formula (3) if the ith curve segment is a non-abrupt sub-curve segment.
Step 3: if the absolute value of the difference between the average curvature of the current real walking path and the average curvature of the virtual walking path is smaller than a preset threshold value, recommending a plurality of target objects in front of the virtual walking path in the current Wen Nong travel virtual scene according to the traveling direction so as to guide the user to search the target objects. The target object can be a simulation of a real scenic spot or a marker in the scenic spot, or can be a region scene or an article which is purely virtually sketched. For example, a certain visually impaired person x walks around a park while holding a terminal, a current real walking path and a virtual walking path can be obtained in the hand-held terminal, if the current real walking path is relatively close to the virtual walking path, the difference of average curvatures of the current real walking path and the virtual walking path is small, and means that the walking direction of the path taken by the visually impaired person towards a certain target is correct or almost correct, a certain marker can be popped up in front of the virtual walking path, a virtual path from the current position to the marker is generated, the visually impaired person x can walk along the virtual path to reach the marker, so that the visually impaired person x can predict that the visually impaired person x hopes to reach the front of the marker in a large probability after the visually impaired person x walks a great majority of paths from the starting point to the marker, and can guide the visually impaired person x to walk through the generated virtual path in the rest path, so that the visually impaired person x can seek by himself and finish the marker by combining with the self-seeking and guiding the visually impaired person x to finish the marker, and seek by himself and seek by seeking the self-seeking the marker successfully.
Wherein, the average curvature of each curve segment under one integral curve segment is obtained, and the average curvature of the current integral curve segment can be calculated according to the formula (4) based on each abrupt sub-curve segment and the non-abrupt sub-curve segment：

The average curvatures of the real travel path and the virtual travel path can be calculated according to the formula (4), respectively, so that whether the two travel paths are relatively close can be compared. The average curvature is adopted to represent whether the travel of the visually impaired person in the two travel paths is consistent, on one hand, compared with the travel of normal persons, the special condition of the visually impaired person is considered, in the process that the real travel of the visually impaired person goes to the target, frequent direction changes are often caused, for example, the travel right in front is switched to the travel right in front of the target by 15 degrees, the change in the small direction is represented to be relatively gentle on the curve of the travel path, and the change is represented to be relatively large on the curve of the travel path only in the case of abrupt change, so that the special condition of the visually impaired person can be represented by the average curvature, and the real intention that the visually impaired person really hopes to go to the destination can be more accurately reflected.

Classifying all target objects in a Wen Nong travel virtual scene, firstly classifying the target objects into two major categories of virtual characters and virtual objects, and classifying the virtual characters into cartoon characters and non-cartoon characters or historical characters or non-historical characters according to the property categories of the characters. The historical characters can be the myth characters, the historic characters and the like. The virtual objects may be divided into mountains, animals, plants, etc., and mountains, hills, waterfalls, rivers, etc. Therefore, the virtual roles and the virtual objects can be divided into layers, the lower the layer is, the finer and more specific the number of units is, and the number of corresponding units is smaller. Therefore, a certain audio unit can be bound to a target object of a certain level in batches, batch binding is realized, the audio unit is matched with the target object, the binding operation amount of the audio unit and the target object is reduced, and the binding efficiency is improved. By hierarchically dividing the target object, different virtual roles and/or virtual objects in the target object can be bound in different hierarchies according to the requirement. For example, for binding audio units in the second level of the virtual object that are adapted to the mountain water, for a plant, the adapted audio units need to be played in the next level of the plant (i.e. the third level) according to the specific category of the plant (e.g. plum blossom). Thereby improving the audio binding efficiency and meeting the audio requirements required by binding different target objects. The target object category to be bound in the audio configuration information includes audio style identification, which is set in advance according to the style class of the audio, for example, a popular song is represented by a number 1, a natural mountain-water song is represented by a number 2, and the like.
