Abstract

BACKGROUND

Visualizing the ultraviolet (UV) dose on skin serve as an intuitive approach to ensure appropriate sunscreen usage and reduce the risk of erythema. UV dose is determined by a number of external factors, such as properties of sunscreens, weather, and type of outdoor activity. We propose a framework for visualizing UV doses that considers various external factors.

MATERIALS AND METHODS

First, the skin of a three-dimensional human model was represented using triangular meshes, and various static postures and dynamic motions were simulated to express outdoor activities. Then, we evaluated the persistency and insufficiency properties of sunscreen, which are time dependent and directly affect the effectiveness of the sunscreen skin protection factor (SPF) during UV exposure. Finally, to calculate the UV dose in real time, we tracked the trajectory of the sun and motion of the skin while considering the time-dependent properties of sunscreen.

RESULTS

An S/W system was implemented based on the proposed framework to visualize the distribution of UV doses through dynamic color changes in exposed skin areas. The color types include true colors, which represent the minimum erythema dose (MED), and pseudo colors representing states before 1 MED is reached. We devised various examples to discuss the usability of the proposed framework.

CONCLUSION

The system conveniently displays the MED according to an individual's skin phototype. When the properties of a wide range of commercial sunscreens are added to the system database, it is expected that the rate of appropriate sunscreen usage by customers will increase.

摘要

背景

在皮肤上直观地显示紫外线 (UV) 剂量,有助于确保适当使用防晒霜并降低红斑风险。UV 剂量取决于许多外部因素,例如防晒霜的特性、天气和户外活动类型。我们提出了一个考虑各种外部因素的 UV 剂量可视化框架。

材料与方法

首先,使用三角网格表示三维人体模型的皮肤,并模拟各种静态姿势和动态运动,以表达户外活动。然后,我们评估了防晒霜的持久性和不足性,这两个特性是时间相关的,直接影响防晒霜的皮肤保护因子 (SPF) 在 UV 暴露下的效果。最后,为了实时计算 UV 剂量,我们在考虑防晒霜时间相关特性的同时,跟踪太阳轨迹和皮肤运动。

结果

基于所提出的框架,实现了一个 S/W 系统,通过暴露皮肤区域的动态颜色变化来可视化 UV 剂量分布。颜色类型包括表示最小红斑剂量 (MED) 的真彩色和表示达到 1 MED 之前状态的伪彩色。我们设计了各种示例来讨论所提出框架的可用性。

结论

该系统方便地根据个人的皮肤光型显示 MED。当将各种商业防晒霜的特性添加到系统数据库中时,预计客户适当使用防晒霜的比例将会增加。
