In this paper, the service robot named “BlackBot” as receptionist robot is descried, that is a small three-wheeled mobile platform with a differential drive, which was controlled by a mini PC. The BalckBot could sense its surroundings with the aid of various electronic sensors while mechanical actuators were used to move it around. Robot's behavior was determined by the program, which was loaded to...
Communication atmosphere in Human-Robot Interaction (HRI) is estimated by integrating emotional states of humans and robots based on the concept of Fuzzy Atmosfield (FA), where human emotion is estimated from bimodal communication cues (i.e., speech and facial expression) and robot emotion is generated by emotional expression synthesis. Fuzzy Analytical Hierarchy Process (FAHP) is used for dynamic...
The authors are developing a talking robot which is a mechanical vocalization system modeling the human articulatory system. The talking robot is constructed with mechanical parts that are made by referring to human vocal organs biologically and functionally. In this study, a newly redesign artificial vocal cord is developed for the purpose of extending the speaking capability of the talking robot...
The ability of robotic rehabilitation devices to support paralysed end-users is ultimately limited by the degree to which human-machine-interaction is designed to be effective and efficient in translating user intention into robotic action. Specifically, we evaluate the novel possibility of binocular eye-tracking technology to detect voluntary winks from involuntary blink commands, to establish winks...
The majority of children with autism face difficulties in social interaction and communication skills. Consequently, in this paper we present a pilot study in which we explored the usability of SpheroTM as a rehabilitation tool for developing social and communication skills. We designed an interactive scenario where children with autism should verbally control the robot and utter voice commands. Our...
Smart homes are an application domain that is inherently connected to explicit and implicit user interaction. Following a user-centred design approach, we have to look at the user's needs and preferences when designing systems and components for smart homes. In this paper, we provide an overview on what users in Germany want and wish from technology in their homes, based on former studies. We focus...
With the widespread use of robots and integration of robots into the daily human life, the communication abilities of the robots are highlighted in order to ensure smooth interaction. Domestic robots with conversation capabilities are getting an increasing demand due to the fact that modern lifestyles are driving elderly community into isolation. One of the requirements of a conversation system is...
Fetching items is an important problem for a social robot. It requires a robot to interpret a person's language and gesture and use these noisy observations to infer what item to deliver. If the robot could ask questions, it would help the robot be faster and more accurate in its task. Existing approaches either do not ask questions, or rely on fixed question-asking policies. To address this problem,...
Speech synthesis systems are systems that provide great convenience to people on user-computer interaction. These systems can read written text as well as they can process human speech artificially. In this study instead of a monotone robotic speech synthesis, the idea is that it is better suited to human nature to have different types of texts sound differently in their own categories. For this process...
Human-robot teams can incorporate advanced technology such as distributed mobile sensor networks, integrated communications, visualization technology, and other means to acquire and assess information. These factors can greatly affect mission effectiveness, safety, and survivability, by providing critical information and suggesting courses of action. However, information overload can result. Tactical...
With the development of smart home technology, the living conditions of people have been improved greatly. However, the aged and the disabled people cannot operate the devices in the home flexibly, so we designed a smart home environment which is controlled by voice. The system can identify the speech signal even if someone else is speaking. At the same time, the system can change the state of lamp...
Real-time detection of a speaker and speaker's location is a challenging task, which is usually addressed by processing acoustic/visual information. However, it is a well-known fact that when a person speaks, the lip and head movements can also be used to detect the speaker and location. This paper proposes a speaker detection system using visual prosody information (e.g. head and lip movements) in...
A few years ago, the home robot has an important role for the human life. Human needs to operate the robot of the work instead for the humans, and some robots can talk with humans speech, such as English language or Japanese language. On the other hand, but Thai language is different from other languages because it is the tonal language, which one word can be pronounced five tones. The most Thai speech...
Laughing response plays an important role in supporting human interaction and communication, and enhances empathy by sharing laughter each other. Therefore, in order to develop communication systems which enhance empathy, it is desired to design the media representation using the pupil response which is related to affective response such as pleasure-unpleasure. In this paper, we aim to enhance empathy...
This paper addresses the problem of sound-source localization (SSL) with a robot head, which remains a challenge in real-world environments. In particular we are interested in locating speech sources, as they are of high interest for human-robot interaction. The microphone-pair response corresponding to the direct-path sound propagation is a function of the source direction. In practice, this response...
We address the problem of ego-noise reduction, i.e., suppressing the noise a robot causes by its own motions. Such noise degrades the recorded microphone signal massively such that the robot's auditory capabilities suffer. To suppress it, it is intuitive to use also motor data, since it provides additional information about the robot's joints and thereby the noise sources. We propose to fuse motor...
In this paper, we present the development of a graphical user interface for a commercially available humanoid robot to study its interaction with children. The interface has been designed to facilitate the overall operation of the robot, and ultimately improve the interaction with children. Four pilot cases are studied to investigate overall effectiveness of the developed robotic setup in interacting...
Currently, studies on learning relationship between objects focus on the text domain. There are a few researchers who focus on relationship learning between objects in other domains. In these researches, they have tried to represent the qualitative description of structure of objects, and the symbolic relationship between them. This output provides symbolic meaning to the inter-object relationships...
A gesture is not performed in only one action but a combination of continuous actions. It is very important to know the start and end of a gesture for accurate gesture recognition. In this paper, to extract a meaningful gesture portion in an online situation, we introduce a method that can distinguish the start and end of a gesture. Then, we describe the method of recognizing an extracted gesture.
In this paper we investigate an Adaptive Line Enhancer (ALE) for the cancellation of robot self-noise. In contrast to many other methods, it requires only a single microphone and can be combined with any other single- and multi-channel noise reduction method. The proposed ALE is implemented in the frequency domain (FDALE) and performs noise cancellation with respect to magnitude and phase. It therefore...
