Elderly population in America is expected to increase significantly in the future. With the increase in age, there is a need for comprehensive health care for elderly people and technology can be used to provide them the required care. Continuous monitoring of elderly activities can help them to live independently and provide help during emergency situations. We have developed a low cost walking activity detection system using copper coated plastic sheets, which act as sensors to sense a person's movements. The data from these sensors is generated from a complex electronics system. We receive and store this data on a plug computer known as Sheevaplug, a low cost linux based computer that acts as a server to forward the sensor data. This data is received using Internet on a graphic application which shows the walking activity of a person. Real time notifications are sent to a pager and a cellphone using Internet based free messaging service during the walking activity. We have tested the whole system in the Columbia health care center and the results show our system is unobtrusive, cost effective, and provides a noninvasive way to monitor the location of elderly. Future research in the reducing the size of sensors, making changes to the sensor data will improve the results of the system.

Our laboratory has implemented a personnel detection system, Smart Carpet, which can detect the walking activities. The existing system uses a SheevaPlug computer to collect and store data which cannot be easily accessed remotely. To make the system user-friendly, we have replaced the data processing parts by using a low-cost computer called Raspberry Pi and the cloud technologies from Godaddy and Google Cloud. Using Raspberry Pi, we meet the requirement of cost efficiency. Using the cloud technologies, we have sufficient computing resources to process the data. The Raspberry Pi and the server communicate over the Internet using Client-Server Model. The system can run by itself 24/7 without interruption. Additionally, we installed a small LCD display on the Raspberry Pi, where the current system status is easily readable. The email and SMS message notifications can be sent to users from the server when certain conditions occur. The data is stored on the server, so a user can access the most current data as well as the historical data from any point. The nearly infinite capacity of the cloud server allows us to make substantial computation and to store them for as long as needed.

This book discusses recent advances in wearable technologies and personal monitoring devices, covering topics such as skin contact-based wearables (electrodes), non-contact wearables, the Internet of things (IoT), and signal processing for wearable devices. Although it chiefly focuses on wearable devices and provides comprehensive descriptions of all the core principles of personal monitoring devices, the book also features a section on devices that are embedded in smart appliances/furniture, e.g. chairs, which, despite their limitations, have taken the concept of unobtrusiveness to the next level. Wearable and personal devices are the key to precision medicine, and the medical community is finally exploring the opportunities offered by long-term monitoring of physiological parameters that are collected during day-to-day life without the bias imposed by the clinical environment. Such data offers a prime view of individuals’ physical condition, as well as the efficacy of therapy and occurrence of events. Offering an in-depth analysis of the latest advances in smart and pervasive wearable devices, particularly those that are unobtrusive and invisible, and addressing topics not covered elsewhere, the book will appeal to medical practitioners and engineers alike.

Falls are a major healthcare problem for the elderly. To help reduce the bad consequences of a fall in the elderly, our laboratory has developed a personnel detection system to monitor walking activities on the floor by detecting the presence of individuals. Then we can process this data to detect falls. This system consists of the sensor installed the carpet and the electronic board. To improve the overall performance of the system, we wanted to modify the electronic board so that we can reduce the 60 Hz noise picked up from the sensor, enhance the sensor data resolution and increase the reliability of the system. We designed and manufactured new boards by replacing the amplifier with a differential amplifier to reduce the noise. We also added an analog to digital converter to increase the data resolution, and finally, using the wired communication protocol I2C instead of the wireless communication system using Zigbee, to improve the system reliability. Lastly, we tested and showed that the differential amplifier can significantly reduce the 60 Hz noise picked up from the sensor. Also, we achieved a higher sensor data resolution from using the analog to digital converter to convert the analog sensor data to digital representation so that our system has a better sensor data resolution to determine the activation of the sensor. Eventually, the I2C successfully replaced the previous wireless system and gives a higher reliability.

Ubiquitous sensors, devices, networks and information are paving the way toward a smart world in which computational intelligence is distributed throughout the physical environment to provide reliable and relevant services to people. This ubiquitous intelligence will change the computing landscape because it will enable new breeds of applications and systems to be developed, and the realm of computing possibilities will be significantly extended. By enhancing everyday objects with intelligence, many tasks and processes could be simplified, the physical spaces where people interact, like workplaces and homes, could become more efficient, safer and more enjoyable. Ubiquitous computing, or pervasive computing, uses these many “smart things” or “u-things” to create smart environments, services and applications. A smart thing can be endowed with different levels of intelligence, and may be c- text-aware, active, interactive, reactive, proactive, assistive, adaptive, automated, sentient, perceptual, cognitive, autonomic and/or thinking. Research on ubiquitous intelligence is an emerging research field covering many disciplines. A series of grand challenges exists to move from the current level of computing services to the smart world of adaptive and intelligent services. Started in 2005, the series of UIC conferences has been held in Taipei, Nagasaki, Three Gorges (China), Hong Kong, Oslo and Brisbane. The proceedings contain the papers presented at the 7th International Conference on Ubiquitous Intelligence and Computing (UIC 2010), held in Xi’an, China, October 26–29, 2010. The conference was accompanied by six vibrant workshops on a variety of research challenges within the area of ubiquitous intelligence and computing.
