1. Lens-Array-Based Variable Moiré Technology for Position, Orientation, and Displacement Measurement

We have developed two types of variable moiré patterns (LEAG and LAMS) generated by combining a microlens array with a fine periodic pattern. Using these technologies, we have developed a high-accuracy marker that enables six-degree-of-freedom (6-DoF) position and orientation measurement with a monocular camera, as well as a displacement sensor that visualizes and measures micron-scale translational and rotational displacements. Through a startup company founded in 2018, we are advancing applications of these technologies in robot control, space development, and various measurement systems. We are also working toward the practical implementation of the displacement sensor for multi-point, long-term monitoring of infrastructure using drones.

2. Implementation Research on Assistive Products and Care Technologies for Human and Societal Augmentation

The implementation of new technologies in the welfare and long-term care fields is challenging because it is influenced by a complex interplay of diverse factors. We support developers in designing evaluation plans to build evidence, and conduct analyses to develop implementation strategies for introducing new technologies. We also provide decision-making support and measure implementation outcomes.

3. International Standardization of Safety for Interconnected Systems in Smart Homes

Safety integration by functional safety and review by AAL viewpoints

Since 2016, we have been proposing guidelines for the safety of various sensors, IoT devices,  smart home appliances and home equipment when they are connected and integrated via home networks as an international standard to the IEC SyC AAL (Active Assisted Living) committee. The acceptable level of risk for in-home integration systems varies depending on the resident’s condition and circumstances (such as age and the presence or absence of disabilities). We are submitting an international proposal—based on consensus among multiple relevant domestic industry organizations—regarding lifestyle support provided by these integrated systems and the approach to determining their acceptable risks.

4. High-Accuracy Visual Marker + XX

We are developing a wide range of applications using high-accuracy fiducial markers. By obtaining highly accurate position and attitude information with a single camera, robot control as well as human movement and motion can be easily and accurately captured as data.

• ＜Use of a High-Accuracy Marker＞
• Proposed Method: Coarse movements are performed manually, while high-accuracy positioning is automated using the marker, achieving both efficiency and accuracy.
• Only Manual Control: Achieving the same level of accuracy (millimeter-level accuracy) using only manual control is too time-consuming.

5. Research on Knitted Sensors for the Realization of “Wear Devices”

We are conducting research toward the realization of “Wear Devices,” in which clothing itself functions as a device. Ideally, a “Wear Device” should have both “sensing” and “intervention” functions. As a first step, we are conducting research on “Knitted Sensor Wear,” clothing that incorporates sensing functionality.

6. Human Motion Analysis and Device Evaluation and Design Using Sensor Wear and Digital Human Models

The condition of blood flow in the extremities, such as the hands and feet, can be measured using light without causing pain. I conduct research on optical measurement technologies and have developed methods for easily assessing impaired blood flow in the extremities and for measuring the contact between a fingertip and an object. I also apply these sensor technologies to the research and development of wearable sensors that can efficiently measure multiple types of physiological information, such as pulse rate and oxygen saturation.

We conduct research on wearable sensing technologies that can measure human movement and physiological states simply by wearing clothing. We are developing technologies to capture shoulder girdle motion using flexible printed circuits integrated with multiple strain sensors, as well as biosignal sensing using soft fabric electrodes. We aim to achieve long-term, unobtrusive human monitoring with high wearability and comfort.

9. Bare finger tactile sensing by using excitation from fingernail

Tactile sensor

We are working on a tactile sensor that estimates finger contact information without covering the finger pad. Since vibrations applied to the finger through the nail change depending on how the finger contacts an object, machine learning can be used to estimate the contact information from these changes. We aim to realize a technology that captures the tactile information involved in delicate fingertip tasks and enables sharing it between remote locations.
