Wearable device for disrupting unwelcome photography

This invention describes a wearable device designed to prevent unwanted photos from being taken of the wearer. It works by using a light source on the device to shine light towards a nearby camera, disrupting its ability to capture a clear image. While the abstract suggests using ambient light or a combination, the primary claim focuses specifically on light generated by the wearable device itself.

Why it matters: Miniaturized electronics, more efficient light sources, and advanced sensor technology have made such a device more practical and effective than in 2013. The increased ubiquity of high-quality smartphone cameras also makes the problem this invention solves more pressing.
