        abstract = {Human–Computer Interaction (HCI) has evolved significantly with advancements in Artificial Intelligence (AI) and Computer Vision. Traditional input devices such as keyboards, mice, and touchscreens often limit interaction in smart environments, robotics, healthcare, and assistive technologies. This paper presents a Virtual Hand Gesture and Voice Command Control System that enables users to interact with computers and IoT devices using natural hand gestures and speech commands. The proposed system employs MediaPipe for real-time hand landmark detection, OpenCV for image processing, TensorFlow-based gesture classification, and speech recognition for voice-controlled operations. The multimodal approach enhances usability by combining gesture recognition with voice commands, thereby improving accuracy and accessibility. Experimental results demonstrate an average gesture recognition accuracy of 97.8% and voice recognition accuracy of 96.5% under normal environmental conditions. The proposed system provides an efficient, touchless, and intuitive interface suitable for smart homes, healthcare, industrial automation, and assistive technologies.},
