The Influence and Analysis of Multimedia Interaction on the Development of Dance

Since ancient times, dance has been widely loved by people. The history of dance has a long history, and people’s pursuit of dance has never stopped. However, with the development of modern technology, traditional dance has been unable to keep up with the pace of the times. Therefore, this article studies the influence of multimedia interaction on the development of dance. This article proposes that multimedia interaction has a great influence on the status quo of dance development. This article aims to study the role of multimedia interaction in dance development. In the eleven years since 2010, the technology of stage effects has developed rapidly. As you can imagine, not only the stage effects can bring a visual feast, but also the development space of dancers has been greatly improved. It can be seen that multimedia interaction is of great significance to the development of dance; with the rapid development of science and technology, multimedia technologies such as computer networks are widely used in all walks of life. The application in the field of dance art is gradually popularized, in which dance teaching and stage performance methods have undergone great changes with the in-depth popularization of multimedia. Therefore, this article must analyze the influence of multimedia interaction on the development of dance.


Introduction
With the development of science and technology, computer technology is used in all elds of people's life, especially the development of Internet technology, multimedia technology, and arti cial intelligence technology has brought a huge impact on human beings. Interactive multimedia is the addition of interactive functions to traditional media, presenting information through interactive behavior and with multiple senses. Audiences can not only see and hear but also touch, feel, smell, and interact with it. It brings people a new experience and is a new form of media, brings advanced scienti c and technological development achievements into the daily dance training environment, uses the rapid development of multimedia technology and communication technology to promote the development of modern dance, and gradually improves the single dance training method. e rapid development of science and technology provides a broader prospect for the development of dance art. Traditional dance art can no longer meet people's aesthetic needs, so new media dance art begins to appear. With the help of dance artists and new media dance groups around the world, various new technologies are introduced into dance performances, and people can discover the new artistic charm of dance. e innovations of this article are as follows: (1) it introduces the theoretical knowledge of multimedia interaction and dance development and uses human body recognition technology to analyze how multimedia interaction plays a role in dance development. (2) e human body recognition technology and support vector machine are expounded. rough experiments, it has been found that the multimedia interaction based on the human body recognition technology can bring bene cial e ects to the development of dance.

Related Work
With the progress of the times, people's pursuit of dance is not limited to traditional dance. e aim of Cha's research was to develop a model of dance emotional competency to improve the ability of dance organizations. To this end, he established the concept of emotional competence in dance, and considered building a model of emotional competence in dance. He divided dance emotional ability into five levels and divided the elements of dance emotional ability into two aspects: recognition and adjustment. Although his starting point is to improve the ability of dance organization, he did not mention how to improve the ability of dance organization nor did he specifically elaborate on the five levels [1].
e purpose of the Choi study was to develop a scale to measure competitive performance stress in college dance majors. To do this, he prepared open-ended questions and examined their validity at expert meetings, followed by an exploratory factor analysis.
Although he prepared openended questions, he did not specify what those questions were or how to check the validity of the method [2]. In order to improve the effect of dance teaching, Wang studied the teaching design and application of dance courses based on 3D holography technology and designed a dance teaching process based on 3D holography technology. He used 3D holographic technology to shoot dances, and based on completing the teaching design, he also carried out practical teaching. His research shows that 3D holography has great advantages in teaching more complex or important dance movements. Although he mentioned that 3D holographic technology will have great significance for dance, he did not explain the advantages of 3D holographic technology in detail [3]. Wang found that immunity is closely related to health. When the body's immunity is strong, the body will be very healthy; otherwise, various diseases will appear. Sports dance takes body movement dance as the necessary content and takes two people or group exercise as the main form of exercise. His research shows that long-term adherence to physical dance can significantly increase serum immunoglobulin levels. However, he has no specific experiments to prove his conclusion is correct [4]. Wu found that computer-aided translation (CAT) based on multimedia interaction is an effective method for translating massive multimedia applications, and it is an essential English learning tool for college students majoring in multimedia technology. English teachers need to improve students' English translation ability through reasonable curriculum settings and guide students to use CAT technology correctly. Although he mentioned that CAT technology can effectively translate English and improve students' English ability, he has no actual case to illustrate the feasibility of this technology [5]. Lam MC found that visual feedback of gesturebased interaction techniques can affect performance, making actions less precise. He studied two new interaction techniques in virtual environments, including visual feedback for grasping. Although he mentioned two new interactive technologies, he did not explain the concept of these two new interactive technologies [6]. Kiourexidou found that the Internet and network technologies have fundamentally changed the way users interact with museum exhibits and that websites and their related services play an important role in that interaction. e purpose of his research was to conduct a heuristic evaluation of usability experts at 47 medical and anatomical museum websites to identify the main characteristics and problems of effective museum website design. However, he has no actual data to illustrate the role of the Internet [7]. Yu found that vocational colleges have sent a large number of graduates majoring in finance and economics to society, but there are very few well-trained talents who can work independently. Aiming at the problems of single multimedia teaching form and unsatisfactory teaching effect in higher vocational finance and economics majors, he proposed an interactive multimedia teaching. is teaching mode can stimulate the interaction between teachers and students and make multimedia teaching more vivid and practical so as to achieve the purpose of improving the effect of multimedia teaching. Although he found that interactive multimedia teaching can improve the quality of teaching, he did not have specific experimental subjects to prove his point [8].

Action Recognition Technology Based on
Multimedia Interaction e inheritance and development of dance as an art form need to use the human body as a carrier and through related movements, music, space, and choreography are combined with each other. Traditional dance has been extended in sacrificial rituals, religious beliefs, etc., to achieve further inheritance and development. After human society entered the twentieth century, science and technology have developed rapidly, and the form of dance art was not only limited to the past form [9]. e combination of multimedia interaction and dance is shown in Figure 1.
As shown in Figure 1, when dance art and media are combined with each other, it also makes the way of dance communication more diverse. Under the influence of the media, dance art can have a more varied and novel stage, breaking the limitations brought by time, space, stage, etc. [10]. In addition, dance art under the influence of media communication will be applied to a large number of virtual technologies, and the form of existence will also present a sense of beauty.
With the rapid development of computer technology, the interaction between people and computers has become a necessary part of all aspects of people's lives. erefore, many researchers have focused on the areas of humancomputer interaction, such as gaze tracking and gesture recognition [11].
In order to effectively obtain features, one must perform specific processing on the obtained target video to deal with redundant information originally mixed in the video; one of the most obvious redundant information in the video is the background [12].

Human Target Recognition Method.
e human object recognition method based on depth image has become a research hotspot in the field of multimedia interaction [13]. e existing human body target recognition based on depth images needs to perform human body detection first and then recognize human body parts on this basis [14].

Background Difference Method.
e background difference method is a general method for motion segmentation of still scenes. It performs the difference operation between the currently acquired image frame and the background image, obtains the grayscale image of the target moving area, and performs thresholding on the grayscale image to extract the moving area. In the background difference method, each frame of the extracted video has a background corresponding to the frame, and the background of the current frame is calculated by the following formula: Among them, f bg (a, b) in formula (1) represents the background of the current frame, and k1(i) represents the weight of the background of the current frame and the background of the previous i frame in this background.

Interframe Phase Difference Method.
e interframe difference method is a method to obtain the outline of a moving object by performing a difference operation on two consecutive frames of a video image sequence. When there is abnormal target movement in the monitoring scene, there will be obvious differences between two adjacent frames of images. Compared with the static background difference method, the interframe difference method has high adaptability to the rapidly changing video, and the foreground image obtained from the current frame picture is shown in the following formula: Among them, f f (a, b) is the foreground image obtained from the current frame image, and f t (a, b) is the original image of the current frame. e optical flow method uses the changes of pixels in the image sequence in the time domain and the correlation between adjacent frames to find the corresponding relationship between the previous frame and the current frame, thereby a method to calculate the motion information of objects between adjacent frames. Moving objects within an image can be inferred from the intensity of light, which is also optical flow. With some information about the light intensity gradient, the pixel at each point in the image is considered to be static [15,16].
Compared with the first two methods, since the optical flow method shows motion information in the image, a certain degree of motion information can be obtained even if the background is unknown [17].

Mixed Gaussian Model Method.
e Gaussian mixture model uses the Gaussian probability density function to quantify things accurately [18]. It is a model that decomposes things into several models based on the Gaussian probability density function. In the assumption of the Gaussian model, it considers that each pixel in a frame image is independent and completely unrelated to other pixels, such as the following formula: where η(a t , μ i,t , τ i,t ) is the ith Gaussian distribution, and μ i,t is the mean of the ith Gaussian distribution. After obtaining the foreground image of the current frame, it is necessary to perform the corresponding binarization operation on the foreground image [19]. Because only converted into the corresponding binarized image, some more obvious features will be found; the binarization process is shown in Figure 2.
As shown in Figure 2, binarization converts grayscale images into binary images. e pixel grayscale greater than a certain critical grayscale value is set as the grayscale maximum value, and the pixel grayscale less than this value is set as the grayscale minimum value, thereby realizing binarization. e angle, length, and other information will not be affected by some unnecessary factors; the formula for binarization is as follows: Among them, R(a, b) represents the processed binarized image and T represents the threshold of binarization.
Due to the great difference in time and space of human posture, the definition of human posture is different, and it is generally divided into two categories: static recognition and dynamic recognition [20]. Static recognition refers to the figure formed by a series of fixed points in space when the human posture remains stationary. Dynamic recognition refers to the action of the human body, which is a series of motion trajectories generated by the human body moving in the space model with time changes [21]. e basic classification of human action recognition is shown in Figure 3: As shown in Figure 3, the application of human motion recognition is mainly used in public places, hospitals, security, and other aspects. e applications of gesture recognition are mostly used in smart home control, perception applications, education and learning, and the expression of people who are not limited by ability. e human body is actually a very complex combination of multisensor data acquisition and information fusion. It can obtain the results wanted to analyze by quickly calculating the data collected by external acquisition systems such as eyes, nose, and hands in various complex and changeable external environments through the brain [22]. e performance of the human body is unmatched by any precision instrument, so it is very complicated to analyze the human body, and a human body model must be established reasonably, as shown in Figure 4.
As shown in Figure 4, when building the model, the human body is divided into several rigid bodies, and the rigid bodies are connected by hinges. e design of the rigid body model has a very large degree of freedom, which can be set according to own needs [23]. Figure 5 is a multirigid body model. e human body is divided into fifteen rigid bodies, and the rigid bodies are connected by hinges. By measuring a certain rigid body, the motion information of the corresponding limb can be obtained [24]. is algorithm performs well in the recognition of singleaction sequences.

Dynamic
DTW distance weakens the strict time requirement of Euclidean distance to a certain extent but maintains the phase similarity, which allows the sequence to be elastically transformed and shifted for identification. It is relatively accurate to use it for classification, as shown in Figure 5.
As shown in Figure 5, it allows the sequence to be elastically transformed and shifted for identification, and it is relatively accurate for classification. in most disciplines, time series is a common representation of data. For time series processing, a common task is to compare the similarity of two sequences. In the time series, the lengths of the two time series that need to compare the similarity may not be equal, and in the field of speech recognition, different people speak at different rates.

Construction of Human Gesture Recognition Algorithm
Based on Support Vector Machine. As a supervised machine learning method, Support Vector Machine (SVM) has been widely used in many pattern recognition scenarios. It includes the last layer of training classification applied to the deep learning network after the automatic feature extraction is completed. It is a very mature learning classification algorithm in the method of supervised classification learning for data points. Its main purpose is to find a segmentation hyperplane on the hyperplane and complete the hyperplane segmentation of two types of samples. e expression formula of the hyperplane is as follows: SVM is a classifier based on the maximum separation hyperplane, which can ensure that the classification results have high reliability. And it has good adaptability to unknown samples.
When the classification problem is nonlinear, it needs to be mapped to make it linearly separable after mapping. e process is shown in Figure 6.
As shown in Figure 6, SVM is a classifier based on the maximum separation hyperplane, which can ensure that the classification results have high reliability. Moreover, it has good adaptability to unknown samples. Nonlinear classification of support vector machines: in addition to linear classification, SVMs can also efficiently perform nonlinear classification using the so-called kernel trick, which implicitly maps its input into a high-dimensional feature space. e Gaussian function has five important properties that make it particularly useful in early image processing. ese properties show that the Gaussian smoothing filter is a very effective low-pass filter in both the spatial domain and the frequency domain and has been effectively used by engineers in practical image processing, In summary, it can be found that in addition to the linear kernel function, the other two types of kernel functions have kernel function parameters that can be adjusted. In addition, since SVM is a classification method for minimizing structural risk, there is a penalty factor that can be adjusted for each type of SVM to control the influence of singular points on hyperplane classification.

3.4.
e Influence of Multimedia Interaction on Dance Development. "Interactivity" is an important feature of new media dance art, part of which is produced through the interactive fusion of new media technology and dance art; these works are also called "multimedia dance." Without physical dance, imagery is meaningless, and without video imagery, the structure of dance cannot be established. e two are indispensable, and the relationship between them is complementary. e interactivity of new media dance is shown in Figure 7.
As shown in Figure 7, the fusion between media communication and dance art is of epoch-making significance. e emergence of media, such as television and the Internet, has Injected vitality into the development of dance and has also broken the limitations brought by traditional stage sets. With the help of advanced media technology, choreographers can imagine and design dances that cannot be performed on the traditional stage with more confidence. On the whole, the emergence of media and the nature of its dissemination have brought many benefits to the development of dance art.   Journal of Electrical and Computer Engineering Both digital technology and artistic practice have made certain progress in today's society, and the two have merged with each other in the process of continuous development. Purely from the perspective of artistic development, the influence of digital technology on dance art has gradually deepened, and the traditional dance form has undergone qualitative changes.

Disadvantages of Traditional Dance and Benefits of Multimedia
Dance. e emergence of multimedia and network communication media cannot be replaced by traditional media because they have their own significant advantages. For example, images, video, and audio can be integrated together, and at the same time, it has strong interaction and inheritance, which will also make the effect of cultural communication better.
In the process of dance art dissemination, the full use of multimedia technology can make the atmosphere on the stage better and bring another impact to the audience, which cannot be achieved by traditional media.
is article investigates 5 dance artists, and their own situations are shown in Table 1.
As shown in Table 1, 4 of the 5 dance artists are female and one is male. It shows that most of the women who learn dance are in the age range of 28-40 years old, and the age range in dance of the five dance artists is between 5 years and 22 years.
is article summarizes and analyzes the benefits of learning dance according to 5 experts, as shown in Table 2.
As shown in Table 2, five experts believe that the benefits of learning dance are: it can improve flexibility, stretch various parts of the body, enhance flexibility and coordination, and increase muscle strength and improve body shape. Among them, 5 experts gave the score range of improving physical flexibility in the range of 7.4 points to 7.9 points. e score range for enhancing flexibility and coordination of the body is 7.3-8.3 points, and the long-term insistence on dancing can increase lung capacity, enhance physical resistance, and reduce the risk of chronic diseases in the score of 8.2-9.1 points.
is article analyzes the problems existing in the development of traditional dance and the characteristics of new media dance, as shown in Figure 8.
As shown in Figure 8, the problems existing in the development of traditional dance are as follows: the technical means are not advanced enough, and the sense of innovation is not strong enough. At the same time, economic factors are also an important factor restricting the development of dance. Among them, the score of technical means is between 3.2 and 4.6, the score of innovation consciousness is between 2.8 and 4.9, and the score of economic factor is between 4.3 and 5.2, all of which are very low.
New media dance is a real-time, interactive, and experiential art. is article compares the development trends of traditional dance and dance based on media interaction from 2015 to 2020, as shown in Tables 3 and 4.
As shown in Tables 3 and 4, the development trend of traditional dance from 2015 to 2020 is generally declining. In the development trend of traditional dance, the popularity of traditional dance has dropped from 53% in 2015 to 30% in 2020, and among the proportion of people who learn traditional dance, the proportion of people who learn traditional dance has dropped from 61% in 2015 down to 19% in 2020. e percentage of growth showed a negative trend. e popularity and percentage of dance trends based on media interaction in 2015 are not as high as those of traditional dance. But since 2016, the development trend of dance based on media interaction has surpassed the development of traditional dance.

e Development of New Media Dance.
e development of new media dance is constrained by science and technology. Under the premise of technological development, the impact of new media on dance development from 2010 to 2021 is reflected in the following aspects-especially the stage effect and development space, as shown in Figure 9.
As shown in Figure 9, the features of human-computer interaction features are more obvious. e development of real-time human-computer interaction and real-time processing technology is gradually improving, and new media dance is gradually becoming the main form of modern dance.
e stage effect is more three-dimensional and delicate. Now mature display technology is being developed, and electronic screens are also appearing. With the advancement of holographic projection technology, the virtual image effect of sci-fi movies is gradually being realized on the stage. e development space is large. With the development of choreography software and network technology, the popularization of new media dance art is an inevitable trend. With the help of specific platforms, amateurs can also create virtual dance works and publish them on the Internet.

Breaking the Limitations of the Traditional Stage.
With the help of the media, dance will not only be limited to dance halls and performances on the stage but will break the limitations of traditional stage. After the broadcast and    Journal of Electrical and Computer Engineering dissemination of the media, the dissemination and coverage of dance will be more extensive, which can be enjoyed by hundreds of millions of audiences at the same time.

Realizing the Integration of Technology and Dance.
At present, the inherent form of dance is gradually broken. Under the influence of media communication, dancers not only have the single attribute of performance onstage but also need to learn how to integrate with some media technologies. For example, in "Shadow Dance," an organic combination of dancing, sound, and light effects is required.
