Abstract
Ambient displays and electronic whiteboards are commonly used to present information during meeting or other appropriate settings. Many times graphical objects are displayed on ambient displays where users of the ambient display will create annotations to the graphical object to provide further comments, meaning, and/or context. Annotations on the ambient display may be recorded for later review. An effective way to present recorded annotations is through a hierarchical system that provides context to the annotations. Annotations may be defined as sets of annotations based upon a logical grouping (e.g. spatial density, temporal density, etc.). These sets can be displayed to users as annotation branches. One method for displaying annotations branches is with a timeline. Depending on where along the timeline a user is, different annotations and/or annotation branches are displayed in relation to one another (e.g. annotation branches that derive from another annotation branch are displayed in a hierarchical manner).
