I-Corps: Ultra Violet Guardian: Real Time Estimation of Pedestrians Ultraviolet Exposure

研究人员试图通过紫外线暴露监测技术为全球行人提供实时紫外线（UV）监测，以保护用户免受阳光过度暴露并帮助预防皮肤癌。志愿者们使用手机设备和蓝牙紫外线传感器，在户外散步，通过定期将紫外线辐射样本上传到该技术的网络服务，为各自地区构建全球紫外线辐射地图做出贡献。综合紫外线读数的子集是匿名的，按地理位置分段，然后通过网页向公众提供基于位置的紫外线辐照度查询。有了智能手机和该技术的应用程序，即使没有佩戴紫外线传感器，普通顾客也可以跟踪累积的紫外线暴露情况，并在出门之前规划旅行路线，以最大限度地减少紫外线暴露。这项技术有可能对近期和长期的健康产生重大影响。近期：(1)通过参与式传感，实时构建全球行人紫外线辐照度地图；(2)在行人走出户外之前估计行人在路径上的紫外线暴露：个人紫外线监测设备可以防止过度暴露，但只能对行人的紫外线暴露进行增量或后处理。从长远来看，这项技术可以用来将行人的紫外线暴露模式与皮肤癌类型联系起来：今天，很少有数据表明紫外线暴露与任何类型皮肤癌的发病有关。如果五分之一的人预计在20-30年后患上皮肤癌，医生可能能够从这项技术的使用者那里获得紫外线暴露的数据，如果他们同意患上皮肤癌。

Researchers seek to provide real-time ultraviolet (UV) monitoring across the globe for pedestrians with an UV-exposure monitoring technology for the purpose of protecting users from sun over-exposure and aiding in skin cancer prevention. Using a cell phone device and a Bluetooth enabled UV sensor, volunteers walking outdoors contribute to constructing a global UV irradiance map in their respective areas, by periodically uploading UV irradiance samples to the technology's web service. Subsets of the aggregated UV readings are made anonymous, geographically segmented, then made available to the general public for location based UV irradiance queries via a webpage. With smart phone and the technology's App, the typical customer, even without wearing a UV sensor, can keep track of cumulative exposure and can plan travel paths that minimize UV exposure before stepping outdoors.This technology has the potential to have significant impacts on health and wellness both near and long-term. In the near term: (1) Build a global UV irradiance map in real-time at the pedestrian level through participatory sensing; (2) estimate the pedestrians' UV exposure traveling along a path before they step outdoors: A personal UV monitoring device can prevent over-exposure, however only performs incremental or post processing of the pedestrian's UV exposure. In the long-term: this technology could be used to correlate the pedestrian's UV exposure patterns with skin cancer types: Today, there is little data that correlates UV exposure to the onset of any type of Skin Cancer. If 1 in 5 people are projected to get skin cancer, 20-30 years from now Physicians may be able to obtain UV exposure data from users of this technology that contract skin cancer provided their consent.
