Action: JR to define "obscure" to allow transparent backgrounds but also raising the possibility of separation where screen real estate is available Obscure: When the onscreen rendering of a visual element prevents another visual element from being visually perceived. Note: While the use of transparent backgrounds for the overlaying visual element (e.g., video captions) is an acceptable technique for reducing obscuration, if space is available it is more effective to avoid overlapping visual elements that are both of interest to the user. ED.: Since we now allow transparency in the SC, we can remove this Note from 1.1.4: "Note: Depending on the screen area available, the display of the primary time-based media may need to be reduced in size to meet this requirement." ------- Sample of usage: - Don't obscure primary media: The user can specify that displaying time-based media alternatives doesn't obscure the primary time-based media; and - Don't obscure controls: The user can specify that the displaying time-based media alternatives doesn't obscure recognized controls for the primary time-based media; and (MR) JAN RICHARDS PROJECT MANAGER INCLUSIVE DESIGN RESEARCH CENTRE (IDRC) OCAD UNIVERSITY T 416 977 6000 x3957 F 416 977 9844 E jrichards@ocadu.ca
