Abstract: Disclosed is a system for identifying a deceleration in a brain activity of a user and reminding the user to take a break to recover from the deceleration of the brain activity. The system includes a smart desk including a sensor unit and a brain activity identification unit. The brain activity identification unit receives (i) user data (such as sleep data, wake up time, and age) from a user device on a particular day, and (ii) sensor data (for example, log-in time, and how long the user is performing the event) for the particular day from the sensor unit. The brain activity identification unit identifies the deceleration in the brain activity of the user based on the user data and the sensor data. The brain activity identification unit is further configured to remind the user to take the break to recover from the deceleration of the brain activity.
