    Style by Demonstration: Using Broomsticks and Tangibles to Show Robots How to Follow People

    The style in which a robot moves, including its gait or locomotion style, can project strong messages, for example, it can be easy to distinguish a happy dog from an aggressive dog simply by how it is moving, and one can often tell if a colleague is stressed simply by the way they are walking. Defining the real-time interactive, stylistic aspects of robotic movements via programming can be difficult and time consuming. Instead, we propose to enable people to use their existing teaching skills to directly demonstrate to robots the desired style of robot movements; in this paper we present an initial style-bydemonstration (SBD) proof-of-concept that focuses on teaching a robot specific, interactive locomotion styles. We present a novel broomstick-robot interface for directly demonstrating locomotion style to a robot, and a design critique by experienced programmers that compares the designing of interactive, stylistic robotic locomotion by our Style-By-Demonstration (SBD) approach with traditional programming methods.

    Style-by-Demonstration: Using Broomsticks and Tangibles to Show Robots How to Follow People

    Robots are poised to enter our everyday environments such as our homes and offices. These contexts present unique human demands, including questions of the style and personality of the robot's actions. Style-oriented characteristics are difficult to define programmatically, and as such, are often out of reach from the designers involved in creating robotic technologies. This problem is particularly prominent for a robot’s interactive behaviors, those that must react accordingly to dynamic environments and actions of people. In this paper, we present the concept of programming robotic style by demonstration through the use of broomsticks and tangibles, such that non-technical designers can directly create the style of actions using their existing skill sets. We developed a working system as a proof-of-concept, and present two novel interfaces for directly demonstrating the style of motions to robots. Our current focus is on the style of a robot following a person, but we envision that simple physical interfaces like ours can be used by non-technical people to design the style of a wide range of robotic behaviors.
