![]() ![]() When the eyes are half-closed or completely closed for a certain number of seconds, it’s a clear indicator of drowsiness. Generally, the movement and position (open/closed) of eyelids denote the state of drowsiness. The main indicator of drowsiness is frequent yawning, which the app should detect and track. Test scenario 4: Driver behavior Test case 1: Frequent yawning The test scenario must compensate with higher precision in case the driver is using any sort of eyewear such as eyeglasses, sunglasses, spectacles or even contact lenses. Test Scenario 3: Eyewearĭrowsiness can be easily identified by analyzing the eyelid movements of the driver or by detecting whether the eyes are open or closed. To recognize them exactly, they must be captured in all possible directions. The position and angle of the driver’s head, along with the face and eye movements, are essential to detecting drowsiness. ![]() Test Scenario 2: Position of the driver’s head and face With poor illumination, it is best to use infrared-enabled cameras for capturing data from the driver’s face and eyes. Poor illumination is an issue at night and in night-like conditions such as driving through a tunnel or a long, unlighted underpass, where daylight cannot penetrate. In conditions of poor illumination, the task of accurately detecting the driver’s facial expression is of even greater importance than in Test case 1. From the lights (whether normal, high beam or fog lights) of oncoming vehicles.Test scenario 1: Illumination conditions Test case 1: With ambient lightįirst, the driver’s face and eyes must be detected accurately in all conditions in which they are illuminated by ambient light, including: If the ML model detects drowsiness, the application alerts the driver.įollowing are the test scenarios. The objective is to test a computer vision-based application that identifies drowsiness by monitoring changes in driver’s face. Test scenarios and test cases for an ML model and app to detect drowsinessĭrowsiness and its effects on driving form the context for this series of test scenarios and test cases. ![]()
