Internet of Things (IoT)
The Internet of Things (IoT) is transforming the way we collect and utilize data in real-world applications. While large-scale industrial IoT systems are widely studied, small-scale, cost-effective deployments remain an underexplored area, particularly in environments where users may have limited technical expertise. My research focuses on developing low-cost, practical IoT solutions that can be easily deployed and used by non-specialist users—especially in smart agriculture and human-centered interface design for aged users.
IoT for Smart Agriculture: Enabling Small-Scale Deployments
Advancements in AI and IoT have led to the development of Smart Agriculture Systems (SAS), improving efficiency in disease detection, irrigation management, and farm monitoring. However, many existing solutions rely on high-end proprietary technology, requiring substantial financial investment and technical expertise to operate. This makes them inaccessible to smallholder farmers—particularly in regions like Japan, where a large portion of the farming population is aging and operates on a non-commercial basis.
To address this, I have developed and deployed low-cost IoT sensor nodes capable of monitoring ambient and soil conditions. These sensors, designed for affordability and reliability, provide real-time feedback on critical parameters such as soil moisture, temperature, and nutrient levels, allowing farmers to make informed decisions about irrigation and crop management. The system also includes a pump control module, which automates irrigation based on sensor readings—reducing manual labor and improving water efficiency.
By focusing on small-scale deployment strategies, my research provides practical and scalable solutions that align with the needs of smallholder farmers, ensuring ease of adoption without reliance on costly infrastructure.
Smart UI Design for Aged Users in IoT Systems
Many IoT systems are designed with technically skilled users in mind, making them difficult to navigate for aged users or individuals unfamiliar with digital interfaces. A key part of my research is developing intuitive, user-friendly interfaces that allow older adults to interact with IoT devices effortlessly.
For instance, in my agricultural IoT deployments, I designed simple, visual-based dashboards that provide clear and concise real-time information, reducing cognitive load for users. The system automatically delivers daily notifications and recommendations based on sensor data, ensuring that farmers receive actionable insights without needing to interpret complex graphs or data streams.
Key principles of my smart UI design for IoT systems include:
Minimalist, text-free interfaces – prioritizing icons and color-coded signals to simplify decision-making. Automated system recommendations – reducing user input requirements while maintaining control. Hands-free and remote control options – enabling easy interaction for users with limited mobility. Low-power, always-on displays – providing continuous feedback without requiring frequent user engagement. By prioritizing human-centered design, my research ensures that IoT solutions are not just technically advanced but also accessible and usable by the people who need them most.
Challenges and Lessons Learned from Real-World Deployments
Deploying IoT systems in small-scale, real-world environments presents unique challenges, including:
Reliability in outdoor conditions – ensuring sensors function effectively despite harsh weather. Low-power operation – designing hardware that remains efficient in remote areas with limited energy sources. Scalability without complexity – developing systems that can expand in functionality without overwhelming users. Bridging the gap between research and usability – ensuring that experimental IoT innovations translate into practical tools. By openly sharing both successes and failures, my goal is to accelerate knowledge transfer in the research community and support the wider adoption of accessible, low-cost IoT solutions.
Collaboration and Future Directions
As IoT technology continues to evolve, I am particularly interested in exploring its intersection with AI, edge computing, and adaptive user interfaces. I welcome collaborations with researchers, students, and industry professionals working on IoT-driven solutions for smart agriculture, human-centered design, and small-scale deployments.
