Understanding the Impact of Laptop Power Saving Options on User Satisfaction Using Physiological Sensors

Several techniques are available to save power consumption in laptop computers. However, their effect on user satisfaction has not been well studied. The authors analyze how user satisfaction is affected by these techniques and show that, within a fixed power budget, some techniques cause more dissatisfaction than others. Second, they study the use of physiological sensors and show that the sensor readings are stable across times when no technique is applied, whereas they show statistically significant changes when power-saving techniques are employed. Finally, they demonstrate a prediction mechanism using these sensors that predicts user satisfaction with over 80% accuracy.
