Research Proposal: Designing a Context-aware Application for Assessment and Visualization of Indoor Environment Quality Background:We usually using environment comfort to evaluate the quality of indoor environment, which is a concept used to measure people's satisfaction with the indoor environment under a certain mental state. whether at work or at home, only good indoor environmental quality can meet our basic needs.However, poor indoor environmental quality will cause discomfort to our body and even more serious diseases.Therefore,It is very important to design a context-aware application that uses basic temperature and humidity sensors to assess indoor environmental quality. After acquiring the collected scene information through Context-aware Application, it can process the information intelligently and provide services for users autonomously. Design:For the overall design problem, the solution is mainly contains two parts.First, the indoor data can be monitored in real time through sensors. For example, the temperature sensor detects and records the indoor temperature change data, and the humidity sensor detects and records the indoor humidity change data.Second, the data recorded by the sensor is transmitted to the mobile terminal device, and the real-time display shows that the data can be seen by the user. If the collected data does not meet the standards of a healthy indoor environment, the mobile terminal can remind the user, and at the same time it can automatically adjust to the normal standard.Moreover, the user can also control the indoor temperature and humidity through the mobile terminal to achieve a good indoor environment standard. Implementation plan: we need some sensors, such as temperature sensor, humidity sensor, etc., to express the temperature and humidity in the form of signals through physical characteristics, such as voltage, current, etc., and then convert the signals into data and transmit them to the mobile end.Analyze and save the data in the mobile terminal, and use computer graphics and image processing technology to convert the data into graphics or images displayed on the screen.The analyzed data will be judged by the algorithm on the mobile terminal whether the current data meets the normal standard. If not, the mobile terminal will generate abnormal information to the user, and the terminal equipment (air conditioner, humidity controller, etc.) will be controlled by the program for adjustment to achieve normal indoor environment quality.Not only that, the user can also control the mobile terminal at any time, and then the mobile terminal can control the terminal device to achieve the desired indoor state.When obtaining the data of the temperature sensor through the mobile end, it needs to see whether the wired mode or the wireless mode is needed. The wired mode can be used through the USB interface. When the temperature data is detected by the single-chip microcomputer, it can be directly uploaded to the mobile end through the UART interface or the USB interface.The Bluetooth module can be added in the wireless way. After the data is collected by the single chip microcomputer, the data is transmitted to the Bluetooth module through the UART interface. Then the mobile end connects to a host module of Bluetooth, and the data sent by Bluetooth can be received. The main problem of this design: how to realize the mobile terminal to respond to the user's situation information and adapt to the dynamic change of the situation by establishing an adaptive adjustment mechanism of context-awareness service.The solution is build an intelligent environment for users and the realization process mainly includes three processes: the perception of situational information, the processing of situational information and the use of situational information.The perception of situational information mainly refers to capturing situational information through user interface input or various built-in sensors.The pr
