We analyzed autonomous conversational spoken interaction as a modality for assistive systems in initial groups of older adults and people with cognitive impairments; we had previously explored this in a WOz setup. Solving a simple task in the domain of week planning, subjects readily interacted with the system. Performance was generally good, but dependent on successful adherence to a specific terse conversational style. Enforcing these patterns in a socially acceptable way during conversation is the next goal for the system.
