- 1. A wearable apparatus for monitoring fatigue and notifying a user, the wearable apparatus comprising:
a motion sensor configured to monitor motion of the user; a notification generator configured to issue a stimulus and to generate a warning to the user in response to receipt of a signal; a processor coupled to the motion sensor and the notification generator, the processor configured to:
obtain a base responsiveness profile of the user for a prescribed motion;
generate a current responsiveness profile of the user for the prescribed motion from the monitored motion of the user in response to the stimulus, wherein the monitored motion includes the prescribed motion;
determine whether the user response to the stimulus exceeds a predetermined threshold of the base responsiveness profile by comparing the current responsiveness profile to the base responsiveness profile; and
send the signal to the notification generator when the user response exceeds the predetermined threshold of the base responsiveness profile; and
a support configured to support the motion sensor, notification generator, and processor on the user.
- 27. A method of monitoring alertness of a user and notifying the user, comprising:
obtaining, with a wearable apparatus configured to measure parameters of a prescribed motion, a base responsiveness profile of the user based on the parameters of the prescribed motion; issuing, with a notification generator, a stimulus to the user to perform the prescribed motion; monitoring, with the wearable apparatus, a response of the user to the stimulus; generating a current responsiveness profile from the user response to the stimulus; determining whether the user response to the stimulus exceeds a predetermined threshold of the base responsiveness profile by comparing the current responsiveness profile to the base responsiveness profile; and generating an alarm to alert the user, with the notification generator, when the response exceeds the predetermined threshold.
