Teaching dermatology to medical students entails a series of lectures, pictures, and hands-on skin examinations to convey a sense of skin features and textures, often by use of simulated skin models. However, such methods can often lack accurate visual and tactile texture representation of skin lesions. To facilitate learning, we have developed a smartphone-based skin simulation model, which provides a configurable visual and tactile sense of a lesion by using the ubiquitous availability of smartphone-based mobile platforms.
A polydimethylsiloxane (PDMS) overlay was used as a configurable translucent elastomer material to model the stiffness and texture of skin. A novel custom smartphone-based app was developed to capture images of various skin lesions, which were subsequently displayed on a tablet or second smartphone, over which the PDMS model skin elastomer was placed. Using the local Bluetooth connection between mobile devices, an iterative feedback algorithm corrected the visual distortion caused by the optical scattering of the translucent elastomer, enabling better virtual visualization of the lesion.
The developed smartphone-based app corrected the distortion of images projected through the simulated skin elastomer. Surface topography of the developed PDMS elastomer provided a more accurate representation of skin texture.
In this investigation, we developed a smartphone-based skin lesion visualization app with a simulated skin elastomer for training/education in not only dermatology but also all general medical specialties that examine the skin. This technique has the potential to advance the educational experience by giving students the ability to see, touch, and feel pragmatic skin textures and lesions.
向医学生传授皮肤病学需要进行一系列的讲座、图片和实际的皮肤检查，以传达皮肤特征和质地的感觉，通常使用模拟皮肤模型。然而，这些方法往往缺乏对皮肤病变的准确视觉和触觉纹理表现。为了便于学习，我们开发了一种基于智能手机的皮肤模拟模型，该模型通过利用基于智能手机的移动平台的普遍可用性，提供病变的可配置视觉和触觉感觉。
使用聚二甲基硅氧烷 (PDMS) 覆盖层作为可配置的半透明弹性体材料，以模拟皮肤的硬度和质地。开发了一种新颖的自定义基于智能手机的应用程序，用于捕获各种皮肤病变的图像，随后将这些图像显示在平板电脑或第二部智能手机上，然后将 PDMS 模型皮肤弹性体放在上面。使用移动设备之间的本地蓝牙连接，迭代反馈算法校正了半透明弹性体的光散射引起的图像失真，从而更好地实现了病变的虚拟可视化。
开发的基于智能手机的应用程序校正了通过模拟皮肤弹性体投射的图像的失真。开发的 PDMS 弹性体的表面形貌提供了更准确的皮肤纹理表示。
在这项研究中，我们开发了一种基于智能手机的皮肤病变可视化应用程序，带有模拟皮肤弹性体，不仅可用于皮肤病学培训/教育，也可用于检查皮肤的所有普通医学专业。这项技术有可能通过让学生能够看到、触摸和感受实际的皮肤纹理和病变来提高教育体验。
