Lumisafe utilizes advanced Time-of-Flight (ToF) sensor technology as a core component of its privacy-friendly fall detection system. Understanding how this technology works is key to appreciating the unique benefits Lumisafe offers, particularly regarding user privacy.

Time-of-Flight sensors are a type of depth sensor. Unlike traditional cameras that capture visual images (like those from your phone or webcam), ToF sensors measure distance. They work by emitting a light signal, often infrared, and then measuring the time it takes for that light to bounce off objects in the environment and return to the sensor. By calculating this time difference, the sensor can determine the distance to each point in its field of view, creating a detailed depth map of the space.

For Lumisafe, this depth map is crucial. Instead of seeing recognizable images of people or objects, the system receives data representing shapes and distances. This data is then processed by Lumisafe's built-in machine-learning models. These models are trained to analyze the depth information to identify specific poses and movements associated with falls, all without ever needing to see what a person looks like.

The fundamental advantage of using Time-of-Flight technology in Lumisafe is its inherent privacy protection. Because ToF sensors capture only depth data and not standard visual (RGB) data, they cannot record identifiable images of individuals. This means that personal appearance, facial features, or any other visual details are simply not captured by the device. This is a critical feature, especially for deployment in sensitive areas like public restrooms, bathrooms, or healthcare facilities where privacy is paramount.

By relying solely on depth information, Lumisafe ensures that the fall detection process is completely anonymous from a visual perspective. The system focuses purely on the geometry and movement within the space, allowing it to accurately detect falls while safeguarding the privacy of everyone present. This commitment to privacy, enabled by Time-of-Flight sensor technology, is a cornerstone of the Lumisafe design, making it a respectful and effective solution for enhancing safety in various environments.
