• Real-Time Hand Control for Interactive Presentation (2026) · doi

  Testing was conducted exclusively on static and dynamic hand gestures with only 20 gesture types from a controlled webcam setup; robustness evaluation is needed for real-time presentation scenarios with occlusions, fast hand movements, complex backgrounds, and varying distances from the camera.

  The paper does not specify which trained model (KNN, HMM, or Markov Model) achieved the 96.5% accuracy; ablation studies comparing these three classifiers on the same hand gesture recognition task with skin segmentation and edge detection preprocessing are missing.

  Existing methods for hand gesture recognition have limitations such as requiring a plain background with a good amount of light and stability.

  We can reduce the error of recognition of gestures more than once for the same task by adding delay to the gesture.
