Exploration of alternative interaction techniques for robotic systems

A robotic system can be considered a computer with the capacity to interact with the real world using sensors and actuators. This article reports on the authors' experiences in developing novel user interfaces for robotic systems, especially in the home environment. High-level control methods that use gestural or speech commands are overly ambiguous or excessively detailed for daily use. The proposed approach is to apply techniques developed in the human-computer interaction field, such as augmented reality and tangible user interfaces, to human-robot interaction. The authors introduce prototype systems such as home appliance control methods using augmented reality, a paper-based method for instructing mobile robots, and various I/O devices to enhance physical interaction with robotic systems. They then discuss lessons learned and directions for future research based on their experiences building these prototype robotic systems and interfaces.
