  The elderly in the future will use smart house technology, sensors, and
robots to stay at home longer. Privacy at home for these elderly is important.
In this exploratory paper, we examine different understandings of privacy and
use Palen and Dourish's framework to look at the negotiation of privacy along
boundaries between a human at home, the robot, and its sensors. We select three
dilemmas: turning sensors on and off, the robot seeing through walls, and
machine learning. We discuss these dilemmas and also discuss ways the robot can
help make the elderly more aware of privacy issues and to build trust.
