This paper presents a new method of human motion recognition based on MEMS inertial sensors data. A micro inertial measurement unit (muIMU) that is 56 mm*23 mm*15 mm in size was built. This unit consists of three dimensional MEMS accelerometers, gyroscopes, a bluetooth module and a MCU (micro controller unit), which can record and transfer inertial data to a computer through serial port wirelessly...
This paper introduces a mobile human airbag system designed for fall protection for the elderly. A Micro Inertial Measurement Unit ( muIMU) of 56 mm times 23 mm times 15 mm in size is built. This unit consists of three dimensional MEMS accelerometers, gyroscopes, a Bluetooth module and a Micro Controller Unit (MCU). It records human motion information, and, through the analysis of falls using a high-speed...
This paper describes a novel approach for human motion recognition via motion feature vectors collected from a micro Inertial Measurement Unit (μlMU), which measures angular rates and accelerations of the three different directions in the workspace based on MEMS sensors. The recognizer is composed of three parts. The first part is a preprocessor, in which Vector Quantization is used to reduce dimensions...
This paper describes the development of a human airbag system which is designed to reduce the impact force from slippage falling-down. A micro inertial measurement unit (muIMU) which is based on MEMS accelerometers and gyro sensors is developed as the motion sensing part of the system. A weightless recognition algorithm is used for real-time falling determination. With the algorithm, the microcontroller...
