System and method for leveraging human physiological traits to control microprocessor frequency
First Claim
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.

Abstract
A system and method for leveraging physiological traits to control microprocessor frequency are disclosed. In some embodiments, the system and method may optimize, for example, a particular processor-based architecture based on, for example, end user satisfaction. In some embodiments, the system and method may determine, for example, whether their users are satisfied to provide higher efficiency, improved reliability, reduced power consumption, increased security, and a better user experience. The system and method may use, for example, biometric input devices to provide information about a user'"'"'s physiological traits to a computer system. Biometric input devices may include, for example, one or more of the following: an eye tracker, a galvanic skin response sensor, and/or a force sensor.

15. A method for managing power consumption of a processor, comprising:
-
receiving dynamic physiological trait user information, generated by biometric input devices, the dynamic physiological trait user information being correlated to user satisfaction; adjusting power consumption of the processor based on the received dynamic physiological trait user information; measuring impact of computer performance on the dynamic physiological trait user information measured by biometric input devices after the power consumption of the processor is adjusted; and in response to measuring the impact of the computer performance, reducing the power consumption of the processor via a dynamic voltage and frequency scaling scheme to a minimum level at which the user is satisfied based on the determined correlation between the user satisfaction and changes in the physiological trait user information, wherein if the power consumption was reduced below the minimum level the user would become dissatisfied. - View Dependent Claims (16, 17, 18, 19, 20)
