## 1. Introduction

With the continuous development of contemporary society, Internet technology is becoming increasingly mature, and this technology has deeply penetrated into people’s lives. Nowadays, as the lifestyle, health needs, and medical concepts of modern people continue to change, people from all walks of life are paying increasing attention to medical problems [1, 2]. Along with the development of science and technology, a series of new medical concepts and service choices have gradually emerged. In China, the problem of aging population is becoming increasingly serious, which has aroused the government’s great attention. Data show that the total population of China in 2012 exceeded 1.35 billion, and the elderly over 65 years old accounted for about 10% of the total population. At the same time, the proportion of China’s elderly population in the total population will continue to rise and will reach a high proportion of 20% in 2040. With the gradual growth of the elderly population, people’s demand for medical services is also gradually increasing. Considering the unique physical conditions of the elderly, their requirements for chronic disease diagnosis and treatment, health monitoring, and other medical services are relatively high [3]. Of course, young and middle-aged people need to bear large work pressure and pension pressure, lack of physical exercise, and irregular life, so their health is relatively poor; there are many health risks. Against this background, there has been a growing focus on how to effectively monitor and manage personal health over the long term. Studies have shown that if effective health management can be implemented, the prevention rate of diabetes, coronary heart disease, hypertension, and other diseases will be greatly improved, and at the same time, some potential chronic diseases can be detected and treated as early as possible.In the traditional medical monitoring systems, people have a strong dependence on medical equipment. Most of these devices are relatively heavy and expensive, and the operation requirements are relatively complex, so they are not suitable for daily occasions [4, 5]. In recent years, the emergence of some family medical equipment has successfully filled the shortage of traditional medical monitoring means. People can easily buy family medical equipment represented by pedometers, sports bracelets, blood glucose meters, blood pressure meters, etc. [6]. These devices are small and easy to use, which can meet people’s basic needs. Objectively speaking, the emergence of the above technologies is inseparable from the rapid development of contemporary wireless sensing technology and the Internet of Things technology [6, 7], and this trend will continue to have a greater impact and change on people’s lives. However, from the perspective of convenience, people need a more intelligent and convenient service platforms to monitor and guarantee their medical monitoring, so intelligent medical treatment arises at the historic moment.Smart healthcare mainly includes the following three contents: first, relying on advanced sensing technology, network communication technology, medical chip technology, and computer technology, we should actively explore and apply mobile medical devices to improve the portability and practicability of such devices. Second, Mobile Health refers to providing advanced, convenient, and humanized medical services and medical information to mobile users on the carrier of mobile networks [4]. Third, the construction of a public platform for medical information sharing, which has regional characteristics, can facilitate the communication between patients and medical workers. Under the smart medical mode, the medical sensor has the characteristics of energy saving and miniaturization. It mainly relies on the mobile platform, overcomes the limitation of medical and health services in time and place, effectively improves the feeling and experience of modern people’s medical and health services, and comprehensively improves the health level of mobile users [8,9]. This can help patients to improve their health monitoring efficiency and can reduce the potential death rate for the elderly. In this sense, APP health service platform is crucial for the people to manage their own health conditions and take measures to reduce the health risks.With the continuous development of the society, people attach increasing importance to health problems. In this context, people from all walks of life have high expectations for the perception of health status and monitoring services, and the birth of all kinds of family-oriented and portable health monitoring APPs has met people’s rigid needs. The powerful Internet of Things function is relied to realize the rapid transmission to the data center; on this basis, the processed and analysed information is fully fed back to the medical staff or the user, so that the medical staff and the user can quickly understand the health status and develop targeted solutions. Accordingly, based on the user needs, it is crucial to design a smart medical APP platform to serve smart healthcare.


## 2. Literature Review

The market for medical devices is expanding rapidly at the same time as the demand for human health is rising. In today’s society, people are under increasing pressure and they have to go back and forth between family and work, so that they have little opportunity and time to do physical exercise. In this context, the disadvantages of the traditional medical model have gradually emerged, and the new medical model mainly based on self-management has gradually stepped onto the stage of history. At the same time, some portable, wearable, personal, home, and easy-to-operate medical monitoring devices are also gradually available. In addition, there are also implanted medical monitoring devices on the market. The emergence of the above equipment effectively makes up for the shortage of traditional large medical equipment and effectively meets the needs of health management of all kinds of people [9]. According to the current research results, compared with China, foreign research in this field started earlier and has acquired mature experience. Next, the research progress at home and abroad is summarized.


### 2.1. Wearable Health Monitoring and Health Nursing

Wearable health monitoring devices and monitoring systems have the following characteristics, light weight, removable, easy to carry, small size, intelligent display, wireless transmission, abnormal alarm, support for a long time, etc., and effectively apply the modern technology represented by sensor technology, wireless communication technology, chip technology, etc. In terms of the present stage, the scientific research personnel of wearable devices, as well as commercial companies, are given the focus on research and development work, also appearing on the market series of home health care equipment, such as household, particle size glucose meter, blood pressure, heart rate, and so on, devices have wireless data transmission function, based on the intelligent terminal, can realize the data real-time transmission and feedback [10]. Wearable devices not only meet the needs of users for medical and health monitoring, but also can not affect their daily life [11], so they are mostly in the form of chest bands, rings, clothing, watches, and so on.


### 2.2. Mobile Healthcare

Martínezpérez et al., after checking 247 papers and more than 3673 mobile medical applications, found that mobile medical application have a wide distribution in diabetes and depression, mostly used for condition monitoring, assist and inform three scenarios, medical assistance and monitoring program use frequency is the highest, information and education aspects of the application use frequency is low [1]. Through literature analysis, Mohammadzadeh and Safdari found that the monitoring and diagnosis system based on mobile health can reduce the medical cost and improve the efficiency in chronic disease management, but at the same time, it faces the risk of information leakage [2]. Sezgin’s study found that mobile anxiety, perceived service availability, and individual creativity were the main influence factors to influence behavior intention, lack of knowledge, and lack of input is considered health application USES the main obstacle [3]. Ahmedani et al. evaluated whether existing diabetes self-management apps followed the guidelines based on the degree of seven self-management behaviors recommended by the American Association of Diabetes Educators and found that most diabetes apps did not meet the evidence-based recommendations [4]. The above studies show that there are still big problems in the software quality of mobile medical applications, and there is a large room for improvement in the future.


### 2.3. Mobile User Health Service Platform

With the progress of society, portable smart devices have become widespread, mainly smart phones and tablet computers [10]. Therefore, it is most convenient to reflect the way that users receive platform services through mobile intelligent devices. Mobile user health service system mainly takes mobile phones and tablets as the carrier and can be divided into the following two types: WAP and APP [11].(2) Health Services. Mobile user health service platform is a service platform for public health. The main problem to be solved is mobile users’ health-related needs. Therefore, the platform not only has the common service content equivalent to other common platforms, but also can customize specific health services.(3) Open and Extensible. The mobile user health service platform interprets the information of the medical information era, which involves diversified elements, such as cloud computing, medicine, nutrition, kinematics, Internet of Things, communication technology, etc., and the integration of technical support in these fields constitutes the service features of the platform. The service experience that the platform can offer is also increasing, so the platform chooses an open management idea to accommodate more diversified health equipment support and health service project participation [12].


### 2.4. Platform Services

To hold intelligent mobile devices provide all kinds of health services is the aim of the mobile customer service platform, the main tasks of the platform are the customer’s personal health records, data analysis, discussion and evaluation of similar data analysis, and professional platform of health advisory services, with the corresponding health institutions of information transfer, hospital outpatient appointment, and all aspects of service, special treatment for special disadvantaged group, control, etc. [13]. From the different types of services provided, to ensure customer health information induction as a basis, specific content form, and the health services by means of induction to a wearable health system for quality of service, the system is closely related to daily life closely, and in preventing disease and customer safety and health regulation has played a very positive role.

## 3. Design of the App Health Service Platform

### 3.1. Smart Healthcare Service System

#### 3.1.1. Demand Analysis

In the development of medical information, health has gradually become one of the topics and enables it to more comprehensively cover the benefits. The reasons why m-health can become an important way of medical information are mainly reflected in three aspects:(1) Eliminate the Imbalance Generated by Information on Health Services. Due to different physical conditions, people over the age of 45 have a higher demand for health information than people under the age group. However, due to the rapid progress of science and technology, they cannot quickly adapt to new products, such as basic computer operations and Internet search information. Therefore, their use of health service information is at a lower level than that of people under the age of 45. As a result, the reception of health service information is unbalanced, so that many health service resources relying on complex networks cannot be effectively obtained, such as registration and expert prediagnosis, which only know the way of face-to-face appointment [13, 14]. With mobile Internet devices, it is less difficult for them to understand online health service information, which makes it convenient, fast, and accurate for people who need this service to increase the usage rate of smart phones, thus reducing the acquisition of knowledge.(2) Health Management with Prevention as the Focus. The survey found that the young people represented by the group only after they suffer from the disease to learn about relevant knowledge or go to the hospital. The prevention of disease and the management of physical health are neglected in daily life. Preemptive health behavior should be promoted as the key content, which also indicates that the medical model is changing from tradition to modernization [14]. Mobile devices are convenient and close to carrying items, can obtain a functional tool, and, therefore, it can realize the medical health services and people’s life is closely linked within easy reach with the app mobile user health service platform to reduce the distance of people’s life and affect its life, let people spontaneously get into the habit of health management [15]. With the deepening of the relevant content of the APP platform, it is also a good tool to promote the further development of the medical model and prevent health problems in advance.(3) Develop Personalized Service Requirements. “Personalization” is also a part of the traditional medical model that needs to be improved. Mobile devices are in contact with people. Therefore, the APP user health service platform can reflect personalized customization and special management to the maximum extent and tailor targeted services based on the different needs and actual situations of different users and their own needs [16].


#### 3.1.2. System Structure

As shown in Figure1, the main structure of the APP health service system is divided into three parts, including the application layer, the network layer, and the perception layer, respectively. Each layer is set up with relevant functional specifications and completes the tasks of this function:(1) Perception Layer. It contains units for centralized information collection and processing, such as portable devices and wearable devices, etc. The main features of the device are small size, energy saving and low power consumption, security, stability, wireless communication connection, and so on. The chip used for medical detection in the medical field is the device, and the environmental monitoring and sensing device can independently complete the acquisition of signals; in addition, it can also rely on the user’s manual operation to record and share the related information content [15]. The actual function of this layer is to collect and process the acquired information data. In general, it can also perform the functions of brief data analysis and continuous display of information.(2) Network Layer. The most critical aspect of APP health service system is the wireless connection mode, which can also obtain the wireless reception of a variety of information. In the portable system, relevant information can be transmitted through Bluetooth wireless connection. In the family and the closed environment at home, ZigfBee and WiFi wireless connection methods of subdevices can be selected. Different technologies are connected to each other, help each other, and improve each other [16]. LAN and personal terminal of operation and family health networks can use a variety of monitoring equipment to get relevant information, and then use the Internet and mobile communication network and the health management platform of cloud interconnected and transport information, the value of the layer is mainly is the hardware device associated with the user, data transfer, storage, and realize the value of information sharing [17].(3) Application Layer. This layer can transmit effective health information and allocate health service items suitable for various intelligences of users. The value of the application layer is reflected in the display of APP health platform and different types of health programs, so that users can get very rich health terminal service [14]. The specific content of this layer is the platform module of APP health services and different types of health-related applications involved in the platform [18]. For example, individuals, family and other user terminals can choose different types of health management application modules, medical professional institutions set up online consulting platform services.Figure 1
Structure of the smart healthcare service system.


### 3.2. Health Information Perception Terminal Design

#### 3.2.1. Demand Analysis and Design Requirements

Health information perception terminal is an integral part of APP user’s health information perception system. Its main value is to complete information perception, preprocessing and transmission, etc. This paper makes the following reflections on the design of the health information awareness APP terminal: the actual requirements of wearables, functional requirements, and the relevant requirements of interaction mode:(1) Wearable Demand Analysis. Wearable products in the use of daily life have a long history, many mobile phones, Apple laptops, digital cameras, and so on; all have very many functions, but such products while carrying are more convenient and simple, but is still need a finger to complete the relevant experience, but does not implement relaxing her hands [15]. Wearable intelligent products are intelligent technological products that are easy to carry and can be worn. The main value of these products is information processing. The wearer can control them and conduct intimate interaction with the device at the same time [19]. Wearable intelligent devices are mainly required for terminals, which do not require manual operation and can maintain the continuity and accuracy of information acquisition in daily life and work.(2) Functional Requirement Analysis. The app information perception terminal contains the content of the diversified single, not only rely on, any terminal need to control the corresponding information-awareness project, it could be only a terminal pressure data analysis and processing task, let the result conform to the actual demand, but also can reduce the consumption of the device’s volume and cost [20]. The first function of the sensing terminal to be utilized is to perceive and preliminarily sort out information. In addition, the communication and data transmission functions are used to complete and control the information transmission of the terminal. App service platforms all have the main function of information perception and transmission. When a person carries multiple health information sensing terminals, each terminal can transmit relevant health information, which will be a great waste of resources [21]. Therefore, the point of view of this paper mainly states that the user management terminal is the best design by using the function of data display; that is, it is placed in the application components of health services to reflect its value.(3) Demand Analysis of Interaction Mode. First of all, the composition of the APP health information perception system is explained. The actual function of the user control terminal is to complete the relevant functions of user interaction. Health information-awareness terminals cannot perform the related work of face-to-face and user interaction [6]. Second, the perception between the terminal and control terminal information flows and exchange, has always been one of the critical processes for the sense terminals will distinguish the pulse/heart rate and dynamic data information transmitted to the next round of terminal control system, the two parts together, that are perceived port terminal and management control information sharing between each other must conform to the wearable and two necessary conditions for data transmission function, so wireless communication way as implementation plan is determined [16].


#### 3.2.2. Module Structure Design

The health information perception system of wearable mobile users needs to establish functional blocks to further complete various necessary function classifications [22]. The module structure of information perception terminal is shown in Figure 2. The sensor module is responsible for the centralized acquisition of all information, and the exchange of information needs to be realized by the wireless communication module. At the same time, the responsibility of the controller module is to analyse and process the information in advance and make each module can exchange information [17]. The required power supply is mainly responsible for the power module:(1) Requirements for Sensor Modules. The design principle of sensor and the way of acquisition are the interference factors of hardware size, cost, and operation form. Taking the pulse/heart rate sensing terminal as an example, indispensable pulse/heart rate data acquisition and analysis of the actual information can explain this function. Wearability or portability requires that the sensor meet the actual requirements in terms of size, quality level, and the way information is collected [15, 16].(2) Controller Module Requirements. Another name of the microcontroller is the controller. The standard of the hardware and operation function of the microcontroller is the clock frequency, which reflects the actual calculation rate of the microcontroller [23]. There is also the maximum capacity of storage on ports (output and input) etc. For the heart rate sensor terminal is not set to advantageous computing speed, ordinary SCM can be controlled by the sensor and meet the basic conditions required for communication [17–19].(3) Communication Module Requirements. About creating awareness of health information terminal must meet the basic design requirements, and easy to carry, the wearable perception between terminal and control terminal information transfer to each other in no wiring communication mode, the wearable perception system of mutual distance scope and management control system port to form the reality of the transmission range not far from 2 meters, so it is necessary to all business accounting cost, power consumption, and practical vision to choose a way to meet the short distance wireless communication [19].(4). As long as the concept of portable power module is involved, both portable and wearable devices need to be equipped with a mobile charging power supply. When the information sensing terminal can play its normal characteristics, the current, voltage, and current of the single-chip microcomputer and sensor must be in the acceptable range before it can be used as the basic module of charging power supply [24].Figure 2
Information-awareness terminal module structure.


#### 3.2.3. Platform Usage Objectives

After designing the app, this platform will include the following features and functions:(1)
There is a high success rate of user operation. The success rate of users with different experience levels at different product levels is 100%, which indicates that the platform has a low threshold for use, low learning requirements for users, and users can easily operate the products.(2)
The user’s operation time is relatively short. In general, users can operate for a short time on the platform, and the operation speed is fast. Most tasks can be completed in less than 1 minute. This is mainly because the platform has a high level of usability and users can operate and use it quickly and conveniently [20].(3)
Users with different experience levels have no significant difference in operation time when operating the same product [21]. This shows that the platform is designed to meet user needs and operating habits, and both novice and experienced users can quickly get started.(4)
Subjective user reviews tend to favor this platform. Users are more likely to use the platform for most features. This is mainly because the operation process of the platform is convenient, the information integration degree is high, and the operation is more intelligent [25]. This further illustrates the level of usability and better user experience of such platforms.In all, after connecting demand analysis, module structure design, and platform usage objectives continuously, we can elaborate the mechanism of health information perception terminal design clearly. Generally speaking, after explaining the demand analysis, we will know how to design the module structure and then we will know the objectives for the platform usage. This can help the users to understand how to use and manage the health monitoring data.


#### 3.2.4. Case Study of the Music APP Health Service Platform

Music therapy mobile APP service platform can organically combine music therapy with online services and provide related users with various services such as music appreciation, social interaction, and news transmission through different sections of content, so that patients can break through the limitations of region and time to receive online music therapy. The homepage of the APP can adopt diversified graphic patterns and bright colors, so that users can feel the warm scene presented by the APP in the first time. At the same time, different functional modules are displayed in columns to echo the different needs of users, so that users can intuitively understand the characteristics of different service contents of the APP. The target audience of the platform is office workers, students, pregnant women, and other people with mental illness due to sensory disorders. High learning and working status, prenatal anxiety, and inhibition will respond to the people to bring huge psychological burden, and music therapy can also be applied to mental illness, hearing impairment, the language barrier, mental retardation, and juvenile crime in the areas of treatment and rehabilitation. Mental nursing, special education schools, prisons, and other institutions can also benefit from music therapy platform. Figure3 shows the structure of this platform.Figure 3

Preemptive health behavior should be promoted as the key content, which also indicates that the medical model is changing from tradition to modernization [14]. Mobile devices are convenient and close to carrying items, can obtain a functional tool, and, therefore, it can realize the medical health services and people’s life is closely linked within easy reach with the app mobile user health service platform to reduce the distance of people’s life and affect its life, let people spontaneously get into the habit of health management [15]. With the deepening of the relevant content of the APP platform, it is also a good tool to promote the further development of the medical model and prevent health problems in advance.(3) Develop Personalized Service Requirements. “Personalization” is also a part of the traditional medical model that needs to be improved. Mobile devices are in contact with people. Therefore, the APP user health service platform can reflect personalized customization and special management to the maximum extent and tailor targeted services based on the different needs and actual situations of different users and their own needs [16].


## 3.1.2. System Structure

As shown in Figure1, the main structure of the APP health service system is divided into three parts, including the application layer, the network layer, and the perception layer, respectively. Each layer is set up with relevant functional specifications and completes the tasks of this function:(1) Perception Layer. It contains units for centralized information collection and processing, such as portable devices and wearable devices, etc. The main features of the device are small size, energy saving and low power consumption, security, stability, wireless communication connection, and so on. The chip used for medical detection in the medical field is the device, and the environmental monitoring and sensing device can independently complete the acquisition of signals; in addition, it can also rely on the user’s manual operation to record and share the related information content [15]. The actual function of this layer is to collect and process the acquired information data. In general, it can also perform the functions of brief data analysis and continuous display of information.(2) Network Layer. The most critical aspect of APP health service system is the wireless connection mode, which can also obtain the wireless reception of a variety of information. In the portable system, relevant information can be transmitted through Bluetooth wireless connection. In the family and the closed environment at home, ZigfBee and WiFi wireless connection methods of subdevices can be selected. Different technologies are connected to each other, help each other, and improve each other [16]. LAN and personal terminal of operation and family health networks can use a variety of monitoring equipment to get relevant information, and then use the Internet and mobile communication network and the health management platform of cloud interconnected and transport information, the value of the layer is mainly is the hardware device associated with the user, data transfer, storage, and realize the value of information sharing [17].(3) Application Layer. This layer can transmit effective health information and allocate health service items suitable for various intelligences of users. The value of the application layer is reflected in the display of APP health platform and different types of health programs, so that users can get very rich health terminal service [14]. The specific content of this layer is the platform module of APP health services and different types of health-related applications involved in the platform [18]. For example, individuals, family and other user terminals can choose different types of health management application modules, medical professional institutions set up online consulting platform services.Figure 1

## 3.2. Health Information Perception Terminal Design

### 3.2.1. Demand Analysis and Design Requirements

Health information perception terminal is an integral part of APP user’s health information perception system. Its main value is to complete information perception, preprocessing and transmission, etc. This paper makes the following reflections on the design of the health information awareness APP terminal: the actual requirements of wearables, functional requirements, and the relevant requirements of interaction mode:(1) Wearable Demand Analysis. Wearable products in the use of daily life have a long history, many mobile phones, Apple laptops, digital cameras, and so on; all have very many functions, but such products while carrying are more convenient and simple, but is still need a finger to complete the relevant experience, but does not implement relaxing her hands [15]. Wearable intelligent products are intelligent technological products that are easy to carry and can be worn. The main value of these products is information processing. The wearer can control them and conduct intimate interaction with the device at the same time [19]. Wearable intelligent devices are mainly required for terminals, which do not require manual operation and can maintain the continuity and accuracy of information acquisition in daily life and work.(2) Functional Requirement Analysis. The app information perception terminal contains the content of the diversified single, not only rely on, any terminal need to control the corresponding information-awareness project, it could be only a terminal pressure data analysis and processing task, let the result conform to the actual demand, but also can reduce the consumption of the device’s volume and cost [20]. The first function of the sensing terminal to be utilized is to perceive and preliminarily sort out information. In addition, the communication and data transmission functions are used to complete and control the information transmission of the terminal. App service platforms all have the main function of information perception and transmission. When a person carries multiple health information sensing terminals, each terminal can transmit relevant health information, which will be a great waste of resources [21]. Therefore, the point of view of this paper mainly states that the user management terminal is the best design by using the function of data display; that is, it is placed in the application components of health services to reflect its value.(3) Demand Analysis of Interaction Mode. First of all, the composition of the APP health information perception system is explained. The actual function of the user control terminal is to complete the relevant functions of user interaction. Health information-awareness terminals cannot perform the related work of face-to-face and user interaction [6]. Second, the perception between the terminal and control terminal information flows and exchange, has always been one of the critical processes for the sense terminals will distinguish the pulse/heart rate and dynamic data information transmitted to the next round of terminal control system, the two parts together, that are perceived port terminal and management control information sharing between each other must conform to the wearable and two necessary conditions for data transmission function, so wireless communication way as implementation plan is determined [16].


### 3.2.2. Module Structure Design

The health information perception system of wearable mobile users needs to establish functional blocks to further complete various necessary function classifications [22]. The module structure of information perception terminal is shown in Figure 2. The sensor module is responsible for the centralized acquisition of all information, and the exchange of information needs to be realized by the wireless communication module. At the same time, the responsibility of the controller module is to analyse and process the information in advance and make each module can exchange information [17]. The required power supply is mainly responsible for the power module:(1) Requirements for Sensor Modules. The design principle of sensor and the way of acquisition are the interference factors of hardware size, cost, and operation form. Taking the pulse/heart rate sensing terminal as an example, indispensable pulse/heart rate data acquisition and analysis of the actual information can explain this function. Wearability or portability requires that the sensor meet the actual requirements in terms of size, quality level, and the way information is collected [15, 16].(2) Controller Module Requirements. Another name of the microcontroller is the controller. The standard of the hardware and operation function of the microcontroller is the clock frequency, which reflects the actual calculation rate of the microcontroller [23]. There is also the maximum capacity of storage on ports (output and input) etc. For the heart rate sensor terminal is not set to advantageous computing speed, ordinary SCM can be controlled by the sensor and meet the basic conditions required for communication [17–19].(3) Communication Module Requirements. About creating awareness of health information terminal must meet the basic design requirements, and easy to carry, the wearable perception between terminal and control terminal information transfer to each other in no wiring communication mode, the wearable perception system of mutual distance scope and management control system port to form the reality of the transmission range not far from 2 meters, so it is necessary to all business accounting cost, power consumption, and practical vision to choose a way to meet the short distance wireless communication [19].(4). As long as the concept of portable power module is involved, both portable and wearable devices need to be equipped with a mobile charging power supply. When the information sensing terminal can play its normal characteristics, the current, voltage, and current of the single-chip microcomputer and sensor must be in the acceptable range before it can be used as the basic module of charging power supply [24].Figure 2

### 3.2.3. Platform Usage Objectives

After designing the app, this platform will include the following features and functions:(1)
There is a high success rate of user operation. The success rate of users with different experience levels at different product levels is 100%, which indicates that the platform has a low threshold for use, low learning requirements for users, and users can easily operate the products.(2)
The user’s operation time is relatively short. In general, users can operate for a short time on the platform, and the operation speed is fast. Most tasks can be completed in less than 1 minute. This is mainly because the platform has a high level of usability and users can operate and use it quickly and conveniently [20].(3)
Users with different experience levels have no significant difference in operation time when operating the same product [21]. This shows that the platform is designed to meet user needs and operating habits, and both novice and experienced users can quickly get started.(4)
Subjective user reviews tend to favor this platform. Users are more likely to use the platform for most features. This is mainly because the operation process of the platform is convenient, the information integration degree is high, and the operation is more intelligent [25]. This further illustrates the level of usability and better user experience of such platforms.In all, after connecting demand analysis, module structure design, and platform usage objectives continuously, we can elaborate the mechanism of health information perception terminal design clearly. Generally speaking, after explaining the demand analysis, we will know how to design the module structure and then we will know the objectives for the platform usage. This can help the users to understand how to use and manage the health monitoring data.


### 3.2.4. Case Study of the Music APP Health Service Platform

The homepage of the APP can adopt diversified graphic patterns and bright colors, so that users can feel the warm scene presented by the APP in the first time. At the same time, different functional modules are displayed in columns to echo the different needs of users, so that users can intuitively understand the characteristics of different service contents of the APP. The target audience of the platform is office workers, students, pregnant women, and other people with mental illness due to sensory disorders. High learning and working status, prenatal anxiety, and inhibition will respond to the people to bring huge psychological burden, and music therapy can also be applied to mental illness, hearing impairment, the language barrier, mental retardation, and juvenile crime in the areas of treatment and rehabilitation. Mental nursing, special education schools, prisons, and other institutions can also benefit from music therapy platform. Figure3 shows the structure of this platform.Figure 3

## 4. Conclusions and Implications

Given the diversity of current intelligent medical service platforms and the existing defects, this study, based on APP health monitoring service platform, in the health service system, designed an efficient platform for smart healthcare with make up for the inadequacy of the wearable health care services from the aspects of system structure and information perception terminal design. This study has important significance for the development of smart healthcare and has strong practical significance in monitoring health, disease early warning, and treatment.With the development of mobile technology, the deepening of intelligent technology, the use of big data, and the construction of smart cities, the future app health monitoring service platform will become more intelligent and convenient. With the development of Internet technology and the advancement of medical information, mobile health will develop comprehensively and deeply [26]. Mobile medical services will develop from a platform that mainly provides registration and consultation services to a comprehensive platform that provides full medical links and full coverage of medical demands. Mobile health care will run through online and offline, covering the pain points of users’ medical scenes, forming a closed loop of online operations and offline medical treatment, and serving patients more comprehensively and efficiently [27].With the continuous development of artificial intelligence technology and sensing technology, intelligent technology will be deeply applied in intelligent medical treatment. Integrating users’ vital signs, exercise data, health records, and electronic medical record data, we can make accurate health status judgments, medical diagnosis, and recommendations from hospital doctors for users’ medical health. The application of intelligent technology will greatly improve the availability level of mobile health, expand the application scenarios of mobile health, and provide users with more intelligent and intelligent services. In addition, medical information construction continues to advance, big data technology in-depth development and application, medical big data will continue to achieve interconnection. With the interconnection of hospital data and the sharing of users’ electronic medical records and health records, the application of medical big data is becoming increasingly extensive. The interconnection of medical big data can effectively solve a series of problems of patients seeking medical treatment and checking in different places and promote the promotion of paperless medical treatment [28]. In the future, the smart medical systems will be integrated with smart city to form a closed loop of service. Some cities have begun to build urban brains to interconnect the traffic data and population data of the city and connect them to smart medical treatment in the future, so that smart cities can better reflect the medical needs of users intelligently and serve users more efficiently and intelligently.Besides, the scene demand of medical service has gradually become prominent, and doctors have begun to seek the improvement of work efficiency and business ability in mobile medical APP, which indicates that APP health service platform will have a great development opportunity in the future. The development process of mobile medical APP health service platform is a process of continuous refinement and deepening from surface to point, from top to bottom. At present, APP like this is mainly aimed at chronic diseases and medical consultation. It is impossible to realize online diagnosis and treatment of emergency cases and severe cases with current technology, but only online monitoring. The more valuable place is that it can play a role in the prediagnosis care of emergency and the guidance and advice of chronic diseases.
