* Energy-Efficient Graphical User Interface Design http://www.ruf.rice.edu/~mobile/publications/eegui_accepted.pdf
From the abstract --
"We demonstrate that energy-efficient GUI (E2GUI) design techniques can improve the average system energy of three benchmarks (text-viewer, personnel viewer, and calculator) by 26.9%, 45.2% and 16.4%, respectively. Average performance is simultaneously improved by 23.7%, 34.6% and 19.3%, respectively." Some general points -- * "proper selection of content placement can improve GUI interaction speed" * "GUIs with better color schemes and contrast ratios are easier to read" * "a GUI should present as few choices as possible" * "a GUI should utilize as much screen area as possible for widgets to be hit. Widgets that are supposed to be hit sequentially should be placed near each other." The examples that the authors give and test have a few new ideas and the rest feel like common sense. One new idea for reading text was neglecting scroll bars and instead using invisible half-screen buttons for page up and page down. The top half of the screen was a page up button, and the bottom half was a page down button. The power-saving color schemes were awful. It looks like the iPhone doesn't care to sip from its battery.
