Jae Min Kim, Minyong Kim, Joonho Kong, Hyung Beom Jang, and Sung Woo Chung, "Display Power Management That Detects User Intent", IEEE Computer Magazine, vol. 44, no. 10, pp. 60-66, October 2011.
In a proposed display power-management scheme, the laptop detects when the user is not looking at the screen, boosting low-power operation to 50 percent and increasing energy savings by up to 13 percent. With the growth of ubiquitous computing has come an increased reliance on laptops over desktops, and display power management (DPM) that prolongs battery life continues to be a critical issue in maintaining that trend.
