How does Chameleon Work

Chameleon consists of four modules that interact with a browser engine, as illustrated in the Figure below.

(1) A model construction module generates a power model, , of the OLED display of the mobile system, using the smart battery interface.

(2) A contribution collection module gathers a color contribution vector,  for each web site from the Layout Calculation and Painting stages of the browser engine in an event-driven manner.

(3) An offline mapping optimization module computes the color map based on  and . Note that Chameleon computes the color maps for all possible user options so that the user can immediately see the impact of a change in user options.

(4) An execution module applies the color map  to transform colors in a web page.
