Face registration
When you register your face in the Configuration wizard, or log in to Windows by face, make sure your face is in the camera frame and there no other faces in the camera's focus. Avoid turning your head at more than a 30-degree angle.
Camera
Different cameras have different optical distortions that may influence face authentication. Therefore, we recommend that you use the same camera for face login that you used to register your face. If you plugged in a new camera, select it in the Settings, delete your current registration data, and register the face again.
Lighting
For better recognition, we recommend homogenous soft lightning. Try to avoid extremely bright light (for example, light from the window, or bright lamp), light falling at an angle (for example, light from the table lamp that stands on one side) and poor lightning conditions.
Face expression
When you register your face, or log in, keep a calm expression on the face. Emotional face expressions (such as laughter, closed eyes, or hair covering your face) can make it can make it difficult, and sometimes impossible, for Luxand Blink! to recognize your face.
If you wear glasses, be aware that recognition can also be hindered by the light reflected from the glasses. Therefore, we recommend that you take off your glasses when you register your face or log in.
Finally, changes in appearance can influence recognition. If you think your look has changed significantly, you should register your face again
