Many types of technology support caregiving: (1) Assistive devices include medicine dispensers, feeding and bathing machines, clothing with polypropylene fibers that stimulate muscles, intelligent ambulatory walkers for those with both vision and mobility impairment, medication reminders, and safety alarms; (2) Telecare devices ranging from ordinary telephones to picture phones. Electronic stethoscopes, glucometers, respirometers, pulse oximeters, and vital sign sensors are among the available telemonitoring devices; (3) Computer-based services include read-only Internet information, software for cognitive improvement exercises, caregiving decision-making support driven by artificial intelligence, and Web-camera conferences that connect family members in different locations; (4) "Smart" homes with sensors identify patterns in daily activities, provide caregiving prompts to administer medications, and send an alert to a monitoring party if a problem such as wandering is detected; (5) Robotic assistants follow older adults to guide them to specific locations in the home and connect electronically to health care professionals, improve orientation by playing recordings of the date and time and of daily activities, and offer social and mental stimulation; and (6) Caregivers with no technologic experience can use such devices and services. Public demand is high for telemonitoring systems, which are sold by unlicensed and unregulated private manufacturers. This article discusses some of these types of technology and briefly describes several Web-based support programs for caregivers.
