Detection method
The camera estimates visible eye openness and, by platform, head-position signals. Processing occurs locally and no camera frames are recorded.
What it may miss
Microsleeps can occur with eyes appearing open. Poor lighting, sunglasses, camera movement, face angle, and hardware differences can reduce reliability.
Phone safety
Mount and configure the device before moving. Never hold, adjust, or interact with the phone while driving, and obey local distracted-driving laws.
Use the right hierarchy
Sleep, breaks, alternate transport, and approved vehicle or workplace systems come first. EyeJolt is an optional extra layer, not a control that makes fatigue acceptable.
