Next, we looked at Vision-Based Systems. These use cameras to track hands, which is a major advantage because it is non-invasive. However, traditional approaches relied on skin color segmentation, which fails if the lighting changes or background skin tones match the user. Newer Deep Learning approaches using 3D CNNs are accurate but computationally heavy. Many also require specialized hardware like depth cameras (Kinect/RealSense), which limits portability.
