Personal space sensor networks for active human computer interaction

肥胖症已经成为一种世界性流行病，缺乏运动每年导致大约200万人死亡。人们对许多工业化社会日益久坐的生活方式越来越感到担忧，因为它是疾病、残疾和死亡的主要潜在原因。II型糖尿病、心脏病和一些癌症的患病率急剧上升，抑郁、焦虑和精神疾病等问题也在增加。除了许多不利的健康后果外，肥胖也有相应的社会污名，只会加剧问题。这些健康后果不仅影响个人，还给卫生保健系统带来压力。有规律的体育锻炼对每个人的身心健康至关重要，无论他或她的体重如何。积极的生活方式可降低患病风险，使身体更强壮、更健康、更灵活。尽管有许多积极的身体和心理影响，许多人仍然没有达到推荐的适度体力活动水平。儿童和青少年尤其脆弱，他们花在视频游戏和其他久坐不动的娱乐上的时间比其他任何活动都多。这些活动往往会使人上瘾并自我强化，使人们很难过上更积极的生活方式，这一事实再加上经济、心理和社会挑战。 我们认为，从久坐不动的屏幕时间转变为更活跃的屏幕时间，将是解决加拿大数字媒体一代即将到来的迫在眉睫的健康问题的关键途径。个人空间传感器网络允许在活动环境中无处不在的计算机控制，这传统上取消了同时使用计算机的资格。交互式应用，特别是娱乐、医疗和健身应用，增加了用户对提供改进的物理沉浸到虚拟环境中的需求。因此，面对无处不在的计算，下一代游戏、交互应用和高级人机交互都需要个人空间传感器网络(PSSN)的研究和开发。

Obesity has become a worldwide epidemic, with physical inactivity contributing to approximately two million deaths a year. There are growing concerns over the increasingly sedentary lifestyle of many industrialized societies, as it is a major underlying cause of disease, disability, and death. There has been a dramatic rise in the prevalence of type II diabetes, heart disease, and some cancers, with problems like depression, anxiety and mental illness on the rise. In addition to the many adverse health consequences, obesity also has a corresponding social stigma that only exacerbates problems. These health consequences not only affect individuals, they also put pressure on health care systems. Regular physical activity is critical to everyone's physical and psychological health, regardless of his or her weight. An active lifestyle reduces risk of disease and makes the body stronger, fitter, and more flexible. Despite the many positive physical and psychological effects, many people still fail to meet recommended levels of moderate physical activity. Children and adolescents are particularly vulnerable, devoting more time to video games and other sedentary entertainment than any other activity. These activities are often addictive and self-reinforcing, making the desire to lead a more active lifestyle difficult, a fact compounded by economic, psychological, and social challenges. We believe that a change from sedentary screen time to a more active form of screen time will be a key way to address the imminent health concerns that are approaching Canada's digital media generation. A personal space sensor network allows for ubiquitous computer control in active environments that traditionally disqualify the simultaneous use of a computer. Interactive applications, especially entertainment, medical and fitness applications, have increased user demand for providing improved physical immersion into the virtual environment. As a result, research and development of personal space sensor networks (PSSN) is required for next generation games, interactive applications, and advanced human computer interaction in the face of ubiquitous computing.
