Interactive Television

Interactive television (iTV) refers to television systems that allow viewers to interact with content beyond simply watching, through features such as voting on polls, accessing supplemental information, navigating menus, and using applications displayed on the TV screen. iTV interfaces are typically controlled via remote controls rather than mice or keyboards, creating unique accessibility challenges including limited input precision, viewing distance considerations, and the need for simplified navigation. Designing accessible iTV is particularly important for older adults who may be comfortable with TV as a medium but unfamiliar with computer-style interfaces.
