Advancements and Applications of Eye Blink Sensor Technology: A Comprehensive Survey
Kush Desai · 2024
This survey explores the multifaceted realm of eye blink sensor technology, emphasizing its broad applications and emerging trends. Eyeblink sensors, leveraging optical, electrodebased, and infrared methods, provide critical insights into human behavior and cognitive processes. This paper systematically examines various fields where these sensors are instrumental, including human-computer interaction, cognitive load assessment, fatigue detection, neuroscience, psychology, user experience, gaming, virtual reality, and healthcare. The review delves into both hardware (e.g., Doppler, EEG, EOG) and software techniques (e.g., CAMshift, Contour Extraction), addressing the challenges and limitations inherent in eye blink detection. Emerging trends such as AI integration, data fusion, and enhanced personalization are discussed alongside ethical and privacy considerations. This comprehensive overview underscores the transformative potential of eye blink sensors, paving the way for innovative applications that enhance human interaction, cognitive understanding, and overall well-being.
