System and Method for Leveraging Human Physiological Traits to Control Microprocessor Frequency
First Claim
1. A system for controlling a computer, comprising:
- a central processor that runs user-centric applications;
one or more biometric input devices that are operatively coupled to the central processor, the one or more biometric input devices providing information relating to physiological traits of a user of the computer,wherein the central 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, andwherein the physiological traits-based power-management system drives the dynamic voltage and frequency scaling scheme based on user satisfaction levels that strongly correlate with changes in physiological traits of the user.

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.
