New Wearable Device Offers Non-invasive Blink Measurement
Researchers are exploring a new way to measure blink characteristics using a wearable eye-tracking device called Neon, developed by Pupil Labs. This device uses infrared cameras to track eye and eyelid movements, capturing data at 200 frames per second.
Key Findings & Benefits:
* Natural Blinking Environment: Unlike traditional lab-based methods (which require chin rests and can feel artificial),the wearable device allows for more natural blink observation.
* Blink Metrics: The device and associated software can break down each blink into its closing and opening phases, providing a range of metrics (amplitude, completeness, velocity).
* Cognitive Load & Blinking: A study with 10 participants showed that blink rate and quality are affected by cognitive load. Participants blinked less frequently and with shorter, less complete blinks while playing a demanding game (Tetris) compared to watching a relaxing documentary.
* Potential Applications: The technology has potential for both research and clinical use, including:
* Dry Eye Disease: Identifying blink-based biomarkers for dry eye.
* Systemic & Neurological Conditions: Potentially detecting indicators of other health issues.
* Future of Health tracking: The article suggests a future where spectacles (like phones) become a source of health data.
In essence, this new device offers a promising, less intrusive method for studying blinking, which could lead to better understanding and diagnosis of various health conditions.
