The 2015 Robotic convention gave plenty of options. Robots or humanoid will become household aids. If you could decide which would be the most useful in your home? The ranks of older and frail adults are growing rapidly in the developed world, raising alarms about how society is going to help them take care of themselves in their own homes. Even though fully functioning robot caregivers may be a long way off, roboticists and physicians predict that a new wave of advances in computerized, robotic and Internet-connected technologies will be available in coming years to help older adults stay at home longer. Loneliness is at epidemic levels among elders in the U.S. today,” said Juliet Holt Klinger, senior director of dementia care and programs at Brookdale Senior Living, one of the nation’s largest providers of assisted living and home care. Brookdale is using a variety of Internet-connected services to help aging clients stay more closely connected with family and friends. Ms. Holt Klinger said there was growing evidence that staying connected, even electronically, offsets the cognitive decline associated with aging. “We have story after story of reconnection with families through Skype,” she added. For all the promising ideas, however, skeptics also note that many ideas are “technologies looking for a solution” that inevitably fail the test of practicality.
