Long-term care helps the elderly perform key day-to-day tasks such as eating, personal care and medication. Today, such care is overwhelmingly manual. However, the cost of manual care is unsustainable in the face of demographic trends. Without dramatic breakthroughs in the cost of care, over half of all elders are expected to be without adequate care within a generation.   This talk describes a series of studies performed at Intel (in collaboration with several major partner organizations including the University of Washington) over the past six years towards understanding how technology may substantially reduce the manual burden of care.
