Abstract:

In  recent years, unhealthy lifestyle has been adopted by an increasing portion of  the human population, which has led to a steady rise of chronic diseases, such  as obesity, cardiovascular disease, cancer, lung disease, and diabetes. Although  the link between lifestyle and health has been well established, there is no  objective method or device to evaluate personal lifestyle. The subjective  self-reporting method in common use is unreliable and inaccurate. We have  developed a wearable computer called eButton, a personal hub collecting multiple  forms of data for assessment of health and wellness. The eButton has a small  size and a light weight, resembling a common circular chest button. The eButton  is a complex miniature computer with a powerful CPU and an array of sensors,  such as a pair of cameras, a light sensor, a motion sensor (accelerometer), an  orientation sensor (gyroscope), a barometer, and a global positioning system  (GPS) receiver. eButton is designed to document health-related events of the  wearer, such as diet, physical activity and lifestyle. This presentation will  give an overview on hardware design of the device and computational algorithms  for food identification, food segmentation, portion size measurement, calorie  expenditure estimation, and sedentary activity assessment in daily life. The  eButton has also been studied to evaluate children’s diet and wellness, monitor  the activity and safety of the elderly, and help the blind and visually impaired  people to find their ways in both indoor and outdoor  environments.
