The stress and poor sleep quality of a person may be used as two of several components for predicting the onset of mental health problems, in particular depression. Ergonomie smart sensors that can determine the heart rate variations related to stress and the variability of sleep may provide unique insights to the coping behavior of stressed people. Rather… (More)
We present an educational and research kit to support hands-on teaching and experience of real-time activity or gesture recognition from on-body sensors. The kit is comprised of: wireless wearable sensor nodes for motion and ECG sensing; software infrastructure for synchronized data acquisition from multiple sensors, data visualization, signal alignment,… (More)
Faced with the challenge of making running speed robots, improved light weight actuation is a primary concern. Pneumatic Air Muscle (PAM) has not been advanced significantly since their conception and some new features are needed to meet compact bi-pedal robots. Driven by air pressure, all PAMs require air control valves that ideally are light weight, low… (More)
In this paper, we consider how low cost wearable sensors may be used to enhance mobile interactions with learning and games multimedia. Unlike camera and single accelerometer based systems, the sensors developed provide measurements for all of the user's limb movements and this data can then be used to recognize what the user is doing anytime anywhere. The… (More)
This paper reports ongoing work in which low cost sensors are combined with high level gesture recognition for automatic training and analysis of Tai Chi. Various feature extraction methods are developed for the sensors and Hidden Markov Modeling is used to classify Tai Chi movements.
The augmentation of human power and endurance by way of a power assisted exoskeleton could revolutionize rehabilitation, industry and the battlefield. The use of servo motors placed near limb joints results in a rotary motion of the human limb which adapts well to attaching the exoskeleton to the limb and to integrate limb movement. Air muscles or… (More)
Increasingly embedded devices are turning to two technologies to achieve high performance and enable efficient programmability as well as product usability. The first is multi-core processing on FPGA devices in which the multi-core architecture allows software to map application-level parallelism to inherent parallel fabric to offer better performance, the… (More)
