The maker of the Roomba robotic vacuum, iRobot -- which we have talked about several times in the past -- has found itself embroiled in a privacy row after its chief executive suggested it may begin selling floor plans of customers' homes, derived from the movement data of their autonomous servants. From a report: While it may seem like the information that a Roomba could gather is minimal, there's a lot to be gleaned from the maps it's constantly updating. It knows the floor plan of your home, the basic shape of everything on your floor, what areas require the most maintenance, and how often you require cleaning cycles, along with many other data points. [...] If a company like Amazon, for example, wanted to improve its Echo smart speaker, the Roomba's mapping info could certainly help out. Spatial mapping could improve audio performance by taking advantage of the room's acoustics. Do you have a large room that's practically empty? Targeted furniture ads might be quite effective. The laser and camera sensors would paint a nice portrait for lighting needs that would factor into smart lights that adjust in real time. Smart AC units could better control airflow. And additional sensors added in the future would gather even more data from this live-in double agent.
