An augmented reality system for teaching sequential tasks to a household robot

Abstract

Abstract—We present a method of instructing a sequential task to a household robot using a hand-held augmented reality device. The user decomposes a high-level goal such as “prepare a drink ” into steps such as delivering a mug under a kettle and pouring hot water into the mug. The user takes a photograph of each step using the device and annotates it with necessary information via touch operation. The resulting sequence of annotated photographs serves as a reference for review and reuse at a later time. We created a working prototype system with various types of robots and appliances. I.
