　View Summary

We propose an alternative approach to find each robotic agent's unique interaction strategies, called Immersing Discovery Method. In this approach, the human manipulator behaves as if she/he becomes the robot and finds efficient interaction strategies based on each robot's shape and modalities. We implement the system including a reconfigurable body robot, an easier manipulation system, and a recording system to evaluate the validity of our method. We evaluate a block-assembling task by the system by turning on and off the modality of the robot's head. Subsequently, the robot's motion during player's motion significantly increases whereas the ratio of confirmatory behavior significantly decreases in the head-fixed design. This result suggests that the robot leads the users and the user follows the robot in head-fixed condition not as in a normal turn-taking interaction style of the head-free condition.

　View Summary

This paper proposes a Blended Reality Agent called "BReA" that can exist in both the real and virtual world and has communicative advantages that is more than simply the sum of those of a robotic agent and an on-screen agent. BReA can seamlessly transfer between the real world and virtual world and users can communicate with BReA without interruption during the transference. We conducted a field test and showed that users can recognize when it points from the virtual world to a real world object after it moves from the real world to virtual world. This result supports a hypothesis that communicating with BReA helps users recognize the link between real world and virtual world objects and virtual world information.

Joint Work, Accepted

　View Summary

FlashTouch is a new technology that enables data communication between touchscreen-based mobile devices and digital peripheral devices. Touchscreen can be used as communication media using visible light and capacitive touch. In this paper, we designed a stylus prototype to describe the concept of FlashTouch. With this prototype, users can easily transfer data from one mobile device to another. It eliminates the complexity associated with data sharing among mobile users, which is currently achieved by online data sharing services or wireless connections for data sharing that need a pairing operation to establish connections between devices. Therefore, it can prove to be of particular significance to people who are not adept at current software services and hardware functions. Finally, we demonstrate the valuable applications in online settlements via mobile device, and data communication for mobile robots. Copyright © 2013 ACM.

　View Summary

The Turing test is an imitation game for determining the intelligence of an agent. In spite of its simplified setting, the use of natural language between two agents in the test is still too high a hurdle for achieving fruitful results in the field of artificial intelligence. In this paper, the authors propose a variation of the Turing test with a restricted communication method. This modified test uses behaviors generated by two-axis actuators for communication instead of the natural language dialogue used in the normal Turing test. This reduction of scope reveals what kinds of features are essential for an imitation game, and broaden the application brought by Turing test. When we learn what sorts of communication become possible with restricted actuation, we can apply this knowledge to any kind of robot or device in the real world. First, we tried to determine what elements are critical for communication between a user and a robot through a preliminary experiment involving human-human communication. A human manipulator received a video image as input and controlled a "robot box" with two actuators in a way that would lead a user to put other objects into the box. The results indicated what kinds of behavior are required to show the intention of the manipulator to the user. Second, we analyzed the result of the preliminary experiment, organized a behavioral model from the result, and programmed the robot box to run the model. The behavior of the robot was programmed according to the user's head and hand locations as identified by a motion captures system. The robot automatically interact with a human without human manipulation with this program. Third, we conducted a behavioral Turing test in a communication task whereby the human collected items according to the instructions of the robot box. In this test, two actuators on the box is controlled both by human manipulator and our program. The answers of users suggests that the users could not identify which is controlled by a human manipulator or the program. This result indicates that the Turing test succeed in a restricted behavioral level. © 2012 IEEE.

Where do you want to use a robotic arm? and what do you want from the robot?

　View Summary

What will users want from robotic arms when they become part for their daily lives? We conducted an online survey to collect ideas from people about the places in which they would want to use a robotic arm and tasks that they would want the robot arm to perform. 96 people anonymously volunteered to participate in this study. More than 240 sets of place and task were identified in the results of two versions of the web-based questionnaires. The results suggest that the household, workplace, and working surface are, respectively, the three most-mentioned places for robotic arm usage in daily life, that participants who were from different countries but were familiar with information technology did not show significant differences in their answers, and that females showed more interest in household and self-care tasks. Our findings can be used as a guideline for future research and development that focuses on daily life tasks for robotic arms. © 2012 IEEE.

TEROOS: a wearable avatar to enhance joint activities.

　View Summary

This paper proposes a wearable avatar named TEROOS, which is mounted on a person's shoulder. TEROOS allows the users who wear it and control it to share a vision remotely. Moreover, the avatar has an anthropomorphic face that enables the user who controls it to communicate with people co-located with the user who wears it. We have a field test by using TEROOS and observed that the wearable avatar innovatively assisted the users to communicate during their joint activities such as route navigating and buying goods at a shop. The user controlling TEROOS could give the user wearing it appropriate route instructions on the basis of the situation around TEROOS. In addition, both users could easily identify objects that they discussed. Moreover, shop staff members communicated with the user controlling TEROOS and behaved as they normally would when the user asked questions about the goods. Copyright 2012 ACM.

We propose an alternative approach to find each robot's unique communication strategies. In this approach, the human manipulator behaves as if she/he becomes the robot and finds the optimal communication strategies using attachable and detachable robot's shapes and modalities. We implement the system including a reconfigurable body robot, an easier manipulation system, and a recording system to evaluate the validity of our method. We evaluate a block-assembling task by the system by turning on and off the modality of the robot's head. Subsequently, the robot's motion during player's motion significantly increases whereas the ratio of confirmatory behavior significantly decreases in the head-fixed design. In this case, the robot leads the users and the user follows the robot as in the turn-taking communication style of the Head-free condition. © Springer-Verlag Berlin Heidelberg 2013.

Pygmy: a ring-shaped robotic device that promotes the presence of an agent on human hand.

　View Summary

The human hand is an appropriate part to attach an agent robot. Pygmy is an anthropomorphic device that produces a presence on a human hand by magnifying the fingerexpressions. This device is in trial to develop an interaction model of an agent on the hand. It is based on the concept of hand anthropomorphism and uses finger movements to create the anthropomorphic effect. Wearing the device is similar to having eyes and a mouth on the hand
the wearer's hand spontaneously expresses the agent's presence with the emotions conveyed by the eyes and mouth. Interactive manipulation by controllers and sensors make the hand look animated. We observed that the character animated with the device provided user collaboration and interaction as though there were a living thing on the user's hand. Further, the users play with the device by representing characters animated with Pygmy as their doubles. Copyright 2012 ACM.
