1. A system for controlling a computer, comprising:

  • a processor that runs user-centric applications;

    one or more biometric input devices that are operatively coupled to the processor, the one or more biometric input devices providing information relating to physiological traits of a user of the computer, the physiological traits of the user being correlated to user satisfaction;

    wherein the processor uses the information relating to the physiological traits of the user to provide a physiological traits-based power-management system, wherein the physiological traits-based power-management system is user-aware due to the information received from the one or more biometric input devices; and

    wherein the physiological traits-based power-management system optimizes a power consumption of the processor via a dynamic voltage and frequency scaling scheme based on the determined correlation between the user satisfaction and changes in the physiological traits of the user to reduce the power consumption of the processor to a minimum level at which the user is still satisfied, wherein if the power consumption was reduced below the minimum level the user would become dissatisfied.
