User Interface Agent

A software component that observes user behaviour and the state of an application, then unobtrusively offers help — suggestions, shortcuts, summaries, or warnings — to reduce workload or prevent errors. In accessibility research, interface agents have been used to monitor a blind user's cursor position in a screen reader, surface skipped content, annotate web pages with extra metadata, or provide context-aware guidance during navigation. Agents can draw on page analysis, machine learning, or human-authored metadata. The design challenge is to stay helpful without being intrusive, which is especially important when the user is already managing a serial audio channel.
