Newsbubble is a tool that allows users to define their own sphere of attention to news and information by setting various filters and parameters. Through the use of sliders and lists, users can pull certain types of information closer to them, such as popular topics from trusted sources, while repelling unwanted content. The interface visually arranges news streams outside the user's bubble based on their settings, and items that meet the parameters will pop into the bubble to be viewed. This gives users more control over their personal news consumption compared to passively accepting what others select.
