Two major challenges in sensor-based measurement and assessment of healthy eating behavior are (a) choosing the behavioral indicators to be measured, and (b) interpreting the measured values. While much of the work towards solving these problems belongs in the domain of behavioral science, there are several areas where technology can help. This paper outlines an approach for representing and interpreting...
In spite of the many efforts to encourage healthier diets, obesity continues to be a serious public health concern in the United States and across the world. Most dietary approaches rely on detailed individual tracking of points or calories, which makes the necessary long-term compliance challenging and ineffective. It has recently been shown that simply monitoring and regulating the number of bites...
The human use of electronic displays (television or computers), also known as “screen time,” is currently a topic of great interest within behavior medicine and general clinical research. This behavior has been linked with a wide variety of pathologies, including obesity, circadian disruption, sleeping disorders, cardiometabolic disease, and socio-emotional behavior disorders in children. As an alternative...
Activity recognition is possible to be used to understand behavior of infants and effective for health and development of children. In our previous study, action of children were assumed as sleeping, sitting, hand motion, walking, running, and playing. Revise of action items were, however, required because it was difficult to calculate calorie consumption in the previous. In this study, 11 action...
This paper is motivated by the growing prevalence of obesity, a health problem affecting over 500 million people. Measurements of energy intake are commonly used for the study and treatment of obesity. However, the most widely used tools rely upon self-report and require a considerable manual effort, leading to underreporting of consumption, noncompliance, and discontinued use over the long term....
The use of accelerometers to approximate energy expenditure and serve as inputs for exergaming, have both increased in prevalence in response to the worldwide obesity epidemic. Exergames have a need to show energy expenditure values to validate their results, often using accelerometer approximations applied to general daily-living activities. This work presents a method for estimating the metabolic...
Today's healthcare delivery system faces numerous problems, such as grey-population and life-style diseases. One such life-style disease is obesity, which has seen a rapid increase over the past decade. It can now be regarded as a global epidemic that can further lead to chronic diseases, such as diabetes, stroke, high blood cholesterol, hypertension and cardiac failure. Nowadays, most people have...
Measuring energy expenditure has a significant role in health monitoring systems. It provides vital information about physical activities that are essential indicators of wellbeing, especially for children. Biofeedback systems are promising methods to monitor and measure daily energy expenditure. In this paper, we present a diet advisory system using biofeedback sensors to monitor children physical...
Human activity monitoring, through the use of body-wearable sensors, allows for many exciting possibilities, from gaming, to exercise, to preventative health care, where childhood obesity is a growing epidemic. The rapidly increasing nature of this trend requires serious thought at targeting its causes and finding solutions. One major influence is video gaming and the hours of sedentary behavior associated...
Obesity prevention requires individuals to have healthy eating and physical activity awareness in their daily lives. New technological products have been explored to help monitoring individual health behaviors. Smart phones are ubiq-uitous hand-held tools with rich embedded sensors and limited computing power. A smart phone is a prospective candidate to integrate physical exercise analysis and food...
Interest in studying human posture, movement, and physical activity is growing due in part to the increasing prevalence of obesity. Accelerometers are commonly used in motion analysis systems to enable researchers to conduct studies outside of the traditional laboratory environment; however the available systems tend to be bulky and unsuitable for long-term studies. Therefore, a need exists for a...
