The system gathers a set of biometric data for a first driver of a vehicle. The system classifies the set of biometric data as belonging in one of a plurality of biometric conditions. The plurality of biometric conditions include at least one normal biometric condition representative of a normal, attentive condition and a first abnormal biometric condition representative of an inattentive condition. The system determines a personal threshold between the normal biometric condition and the first abnormal biometric condition for the first driver for a first biometric parameter. In a driving phase, the system monitors biometric data of the first driver to determine whether the first driver has passed from the normal biometric condition to the first abnormal biometric condition according to the personal threshold. If the first driver has passed to the first abnormal biometric condition, the system presents a dialog personalized for the first user designed to return the first driver to the normal biometric condition.
Please help me write a proper abstract based on the patent claims. CLAIM: 1.

Apparatus, comprising: a processor; computer memory holding computer program instructions executed by the processor for personalized driving safety, the computer program instructions comprising: program code, operative to gather a set of biometric data for a first driver of a vehicle; program code, operative to classify the set of biometric data as belonging in one of a plurality of biometric conditions, the plurality of biometric conditions including at least one normal biometric condition representative of a normal, attentive condition and a first abnormal biometric condition representative of an inattentive condition; program code, operative to determine a personal threshold between the normal biometric condition and the first abnormal biometric condition for the first driver for a first biometric parameter; program code, operative to monitor biometric data of the first driver to determine whether the first driver has passed from the normal biometric condition to the first abnormal biometric condition according to the personal threshold; and program code responsive to a determination that the first driver has passed to the first abnormal biometric condition, operative to present a dialog personalized for the first user designed to return the first driver to the normal biometric condition. 10. The apparatus as recited in claim 9, further comprising program code, operative to dynamically update the personal threshold according to an external factor, wherein an external factor is external to the driver and the vehicle. 11. The apparatus as recited in claim 9, further comprising program code, operative to dynamically update the personal threshold according to a recent activity, the recent activity performed prior to a driving phase. 12. The apparatus as recited in claim 9, wherein the first abnormal biometric condition is a member of a plurality of inattentive conditions and the method further comprises selecting the dialog personalized for the first driver for the first abnormal biometric condition from a set of dialogs, each dialog of the set of dialogs designed for the first driver to return the first driver to the normal biometric condition from a respective one of the plurality of inattentive conditions. 13. The apparatus as recited in claim 12, further comprising program code, operative to select the dialog personalized for the first user for the first abnormal condition from a set of dialogs is according to a history of the first driver wherein the dialog personalized for the first user for the first abnormal condition was successful in returning the first driver to the normal biometric condition. 14. The apparatus as recited in claim 11, further comprising: program code, operative to prompt the first driver to confirm the first abnormal biometric condition; and program code, operative to classify a subset of the biometric data to the first abnormal biometric condition according to the first driver response in the dialog stage. 15. A computer program product in a non-transitory computer readable medium for use in a data processing system, the computer program product holding computer program instructions executed by the data processing system for personalized driving safety, the computer program instructions comprising: program code, operative to gather a set of biometric data for a first driver of a vehicle; program code, operative to classify the set of biometric data as belonging in one of a plurality of biometric conditions, the plurality of biometric conditions including at least one normal biometric condition representative of a normal, attentive condition and a first abnormal biometric condition representative of an inattentive condition; program code, operative to determine a personal threshold between the normal biometric condition and the first abnormal biometric condition for the first driver for a first biometric parameter; program code, operative to monitor biometric data of the first driver to determine whether the first driver has passed from the normal biometric condition to the first abnormal biometric condition according to the personal threshold; and program code responsive to a determination that the first driver has passed to the first abnormal biometric condition, operative to present a dialog personalized for the first user designed to return the first driver to the normal biometric condition. 16.
