Virtual Keyboard Using Eye-Blinking

The advancement of assistive technologies has significantly transformed the landscape of human-computer interaction, particularly benefiting individuals with physical disabilities who face challenges in using conventional input devices. Among these innovative solutions, the virtual keyboard controlled by eye blinking has emerged as a crucial tool, providing a practical and efficient means of communication and control for individuals with severe motor impairments. Eye-blink-based virtual keyboards typically function through the detection of intentional eye blinks, which are distinguished from natural, involuntary blinks to reduce false inputs. Recent advancements have incorporated machine learning models, such as convolutional neural networks (CNNs), to enhance the accuracy of blink detection and adapt to individual blinking patterns.
