Monitoring Mom

Eric Dishman is making a cup of tea-and his kitchen knows it. At Intel's Proactive Health Research lab in Hillsboro, OR, tiny sensors monitor the researcher's every move. Radio frequency identification tags and magnetic sensors discreetly affixed to mugs, a tea jar, and a kettle, plus switches that tell when cabinet doors are open or closed, track each tea-making step. A nearby computer makes sense of these signals; if Dishman pauses for too long, video clips on a television prompt him with what to do next. It's all part of a growing effort at Intel and other labs around the country to develop ways to help the elderly, and others who need assistance with everyday activities.
