A design trend for modern computing is to create calm technology for machines to assist people without explicit interaction. Similar concepts can also benefit Human-Robot Interaction (HRI). Instead of explicitly interacting with robots to complete tasks (robot-centric design approach), users can interact with tasks directly (task-centric design approach), and robots only perform these tasks in the background. We implemented a paper-tag based interface to support task-centric HRI in a sensor augmented home environment. Tasks (house work) are assigned using paper tags placed on corresponding real world objects and environment. Robots avoid disturbance to the host and work while hosts are away. Our initial user studies show that paper-tag based task-centric HRI are particularly simple to use.
