Intelligent Assistance is the assistant-facing application of spatial intelligence: an agent must perceive a user’s lived environment, remember its changing state, ground natural instructions in that state, and act in ways that are useful, legible, and safe. Unlike a task-specific robot in a factory, vehicle, or clinic, a personal assistant operates in homes, offices, streets, and wearable or XR interfaces where the scene is private, cluttered, and shaped by individual routines. This chapter therefore treats assistance as a persistent human-centered loop over spatial memory, language grounding, action, and feedback. The same spatial model supports tidying and search, close collaboration, and accessibility support for vulnerable users, but each setting changes how much the assistant must model the person as well as the place.
