Fiona’s frail 88-year-old father lives alone in a small apartment. He is making a cup of tea and his kitchen knows it. Tiny sensors monitor his every move and track each tea-making step. If he pauses for too long, a nearby computer reminds him about what to do next. Later that day, Fiona accesses a secure website and scans a checklist, which was created from the computer in her father’s apartment. She finds that her father took his medicine on schedule, ate normally, and continued to manage his daily activities on his own. This puts Fiona’s mind at ease.
