We propose a method for real estate information exploration in VR. It is difficult to find a real estate property that matches the user's preferences from many properties. Each real estate property has multiple attributes such as rent, layout, nearest station, and so on. In web services for real estate information exploration, search results are usually displayed in a list similar to a standard Web search. Listed search results are not suitable for an overview of the information. We have developed an interface for information search that enables the user to overview real estate information in VR with an unlimited display area. In the proposed system, the user can select a target attribute or narrow down the results by attribute values. Real estate information is displayed as a panel in which information on several real estate properties is gathered. When the user physically gets closer to the panel, more detailed information is presented on the panel. In other words, level of detail (LoD) control by physical distance is implemented. Thus, the proposed system can intuitively and seamlessly switch between an overview of overall information and a presentation of detailed information. Users evaluated the LoD controls to be easy to operate.

This paper presents an innovative design and implementation of a wireless sensor module using low-power Internet of Things (IoT) technologies for applications in geotechnical engineering and structural diagnostics, with a main focus on monitoring rock formations below the water surface in areas without access to electrical power. Designed for continuous monitoring of linear displacements and other critical parameters in structural engineering, geotechnical engineering and engineering diagnostics, this sensor module is particularly useful in remote locations. Utilizing wireless data transmission and advanced IoT technologies such as LoRa, IQRF and NB-IoT, this system allows for flexible coverage options and efficient remote management. The system allows users to remotely change measurement parameters, the period of messaging and set thresholds for alarm activation. The study highlights the importance of innovative IoT solutions to improve accuracy and efficiency in monitoring geotechnical and civil engineering structures, especially in challenging sub-surface environments, opening new opportunities for predictive maintenance and risk management in these specific applications.

With the development of low-cost microcontrollers, sensors and wireless communications, intelligent environment monitoring based on the Internet of Things (IoT) has become possible. In this paper, an indoor environment monitoring system constructed by sensor network is realized. The system consists of distributed sensing nodes, which contain temperature and humidity, human infrared, voice recognition and camera sensors, etc. The nodes are connected to STM32 microcontrollers and WIFI modules and are scheduled in real time using free real time operating system(FreeRTOS). The visual and time series sensing data are transmitted to the server via WIFI in real time, and the user can monitor the system remotely by using the PYQT interface program on the PC. The system can also control home appliances by voice. The data interaction uses self-built WIFI module in AP mode for SOCKET communication. Through rigorous testing, the system demonstrates the capability of data communication, low-latency video streaming, and bidirectional control. The sensor network and real-time OS based architecture utilizes parallel execution to balance different temporal tasks and realize an agile cyber-physical system. This paper provides a reference for the underlying software infrastructure of intelligent buildings, embodying the integrated application of real-time scheduling, sensor networks and human-computer interaction.

Nowadays, ensuring optimal battery performance is indispensable, especially in autonomous navigation scenarios. Our research aims at revolutionizing battery monitoring through a cost-effective, highly reliable system applying Kalman observer and ATMega08 microcontroller technologies. We initiate with methodical sensor identification experiments to evaluate precision and linearity, followed by behavior modeling. Implementing a Kalman filter-based observer on the microcontroller enables precise state of charge (SOC) monitoring by effectively correcting errors and filtering noise. Our system's adaptability is demonstrated through successful validation across various battery types, including lithium-ion and lead-acid, with a focus on parameters like voltage, current, power, and SOC. By introducing an interruptions during discharge, the proposed system accurately tracks voltage fluctuations, like a 1-volt change from 10.3 V to 9.3 V, providing reliable SOC indications, crucial for optimal energy management in autonomous navigation. Furthermore, we enhance data acquisition quality through a user interface LabVIEW, continuously integrating with our monitoring system for optimal energy management insights during navigation.

Ensuring a good and healthy workplace environment for employees is of paramount importance, considering the significant amount of time spent at work. Achieving effective monitoring and control of the work environment necessitates the utilization of a microcontroller-based board equipped with an array of sensors and actuators. These sensors are strategically positioned within the cabin where an employee typically works, constantly monitoring various environmental variables. The collected data is aggregated and processed within an ESP32 microcontroller, utilizing predetermined custom threshold values. Based on the processed data, informed decisions are generated, triggering specific signals to the respective actuators. These actuators play a crucial role in adjusting environmental variables within the cabin, striving to create a comfortable and pleasant ambiance for the employee. The results obtained from the sensors and the subsequent actions of the actuators are not only communicated but also stored in both local and cloud-based memory systems. This is facilitated through the application of the secure message telemetry transport (smqtt) protocol, enabling seamless data transmission and storage. In the development of this intelligent workspace, careful attention has been given to ensure an effective system that strikes a balance between efficacy, reasonable cost, and a user-friendly interface. The design process incorporates a simple user interface design application, focusing on ease of use and accessibility. Furthermore, a comprehensive discussion concerning the trade-off between essential factors and cost has taken place, aiming to achieve the best possible outcome. In summary, this research advocates for the creation of an ergonomic and health-conscious work environment through the integration of advanced monitoring and controlsystems within office cabins. The proposed system, utilizing cutting-edge technology, aims to enhance employee well-being, productivity,
