Vehicle interior monitoring system for controlling device input
A recently granted patent (Publication Number: US11951833B1) describes an innovative apparatus designed for use in vehicles to enhance safety and prevent driver distraction. The apparatus includes an interface to receive pixel data of the vehicle's interior and a processor that processes this data as video frames. Through computer vision operations, the processor can detect objects, extract characteristics, associate movement of a body part with a specific person in the vehicle, and generate a control signal in response to the movement of that body part. Importantly, the device operates in a locked mode while the vehicle is in motion, preventing input, but the control signal enables input when the device is locked, ensuring that the driver remains focused on the road.
The patent details the intricate workings of the apparatus, including the application of feature detection windows, convolution operations, and feature extraction based on weight values. The processor can distinguish between different occupants in the vehicle, enabling it to disable the control signal if the driver is alone in the vehicle. By correlating input with the movement of a specific body part, the apparatus ensures that the driver's attention is not compromised. Additionally, the apparatus provides context to the device, enabling it to differentiate between inputs from different occupants and prevent driver distraction effectively. This technology aims to provide an advanced infotainment system permission control while driving through in-cabin monitoring, ultimately enhancing safety and reducing distractions on the road.
