A method for operating a cognitive monitor includes measuring a cognitive tone of a user, determining a categorization of the cognitive tone of the user, selecting an effector using the categorization of the cognitive tone of the user, wherein the effector is selected to achieve a predicted future cognitive tone in the user, and applying the at least one effector using a feedback mechanism of the cognitive monitor
Please help me write a proper abstract based on the patent claims. CLAIM: 1. A method for operating a cognitive monitor, comprising: measuring, using at least one sensor of the cognitive monitor, a cognitive tone of a user; determining, using at least one processor of the cognitive monitor, a categorization of the cognitive tone of the user; selecting an effector, using the at least one processor of the cognitive monitor, using the categorization of the cognitive tone of the user, wherein the effector is selected to achieve a predicted future cognitive tone in the user; and applying the at least one effector using a feedback mechanism of the cognitive monitor. 2. The method of claim 1, wherein measuring comprises accessing communications data of the user. 3. The method of claim 1, wherein measuring comprises determining a current location of the cognitive monitor. 4. The method of claim 1, wherein measuring comprises taking a physical measurement of the user using a sensor. 5. The method of claim 1, wherein determining the categorization comprises: mining data for the current cognitive tone of the user and state information about the user over a time period; and evaluating the current cognitive tone of the user over the time period to determine the categorization. 6. The method of claim 5, wherein applying the at least one effector comprises issuing an alert. 7. The method of claim 7, wherein the alert comprises adjusting a light output of the cognitive monitor. 8. The method of claim 7, wherein the alert comprises adjusting a tactile output of the cognitive monitor. 9. The method of claim 7, wherein the alert comprises outputting an audible alert from the cognitive monitor. 10. The method of claim 3, further comprising: tracking a location of the user; and adjusting the location of the cognitive monitor using the location of the user. 11. The method of claim 1, further comprising analyzing, using at least one processor of the cognitive monitor, the cognitive tone of the user to predict a plurality of different future cognitive tones of the user corresponding to different effectors. 12. The method of claim 1, wherein the predicted future cognitive tone of the user is predicted using electronic calendar data of the user. 13. The method of claim 1, wherein measuring comprises determining an ambient environment. 14. The method of claim 1, further comprising receiving input on an interface of the cognitive monitor about a current cognitive tone of the user.
