A method from Microsoft Asia and Tsinghua University demonstrates that a good way to adapt web pages on small
screens is to collapse irrelevant content [9]. They categorize column menus, archive material, and advertising as irrelevant, and thus candidates for being collapsed. Collapsing content causes all remaining content to expand in size, revealing more detail, which increases the user’s chance of identifying relevant content. Thus method has been tested on a PDA, which is provided with four commands for collapsing content areas at different granularities along with an option to switch to a full-size view.
