User feedback on physical marker interfaces for protecting visual privacy from mobile robots

We present a study that examines the efficiency and usability of three different interfaces for specifying which objects should be kept private (i.e., not visible) in an office environment. Our study context is a robot “janitor” system that has the ability to blur out specified objects from its video feed. One interface is a traditional point-and-click GUI on a computer monitor, while the other two operate in the real, physical space: users either place markers on the objects to indicate privacy or use a wand tool to point at them. This late-breaking report presents qualitative feedback from users for improving the interfaces.
