Electronic device with fatigue detection function

An electronic device with a fatigue detection function, comprising:

• a keyboard comprising at least one key;
• a key detection circuit detecting a pressing state of the key to generate a first detection signal;
• a first processing circuit converting the first detection signal to a first processing signal;
• a control circuit determining whether a specific event occurs according to the first processing signal, wherein in response to the specific event occurring, the control circuit sends a reminder signal;
• a display screen displaying a reminder image according to the reminder signal;
• an image detection circuit detecting a face of a user to generate a second detection signal;
• a second processing circuit processing the second detection signal through a first algorithm to generate a second processing signal;
• and
• a distance detection circuit detecting whether an object is close to the display screen to generate a third detection signal,
• wherein:
• the first algorithm is applied to analyze changes in the user's eyes, the user's mouth, or both,
• the second processing circuit processes the third detection signal through a second algorithm to generate a third processing signal;
• the control circuit determines whether the specific event occurs according to the first, second, and third processing signals.
