We need to clarify features of human speech to make assistive robots more human adaptive. In this study, we focused on speech produced in human-human virtual collaborative conveyer task and transcribed all utterances spoken while completing the task. We computed morphemes (words or meaningful parts of words) by word class categories. The results were that the total number of morphemes spoken in each trial decreased over ten trials. We found that a strong negative correlation between the number of morphemes by type in each trial and the number of trials. Task general verbs remain while task specific verbs decreased. Among the task specific verbs, verbs with more wide meaning tend to remain. Results suggest that in accordance with acquiring skill for the task, the entire complexity of ontology decreases and becomes more efficient.

Technology and science have been developing rapidly, and robotic system for human support has been researched recently. Considering the effect of low birthrate and longevity, this system is thought to become important in the future. In this research, environmental embedded haptic system for human support is developed. Action recognition and support is realized by the concept based on the modal transformation, which is often used for haptic research. In order to realize this system, variable impedance control based on making a choice of environmental modes is proposed. This system enables action recognition and support for human motion. The validity of the proposed method is shown by the experimental results.

Recently, the field of real-world haptics which deals with force information has been widely researched. In order to acquire haptic information which is fed back to operator from a remote environment, a master-slave system is constructed and bilateral control is implemented to the system. Transmitting haptic information has many advantages for tele-operations, human support system and so on. In the tele-operation, operator mainly manipulates the instruments only based on visual information conventionally. Due to the lack of haptic information, there are some possibilities that the instruments and the environment are broken. So, by applying bilateral control to the tele-operation system, they can operate on the basis of not only visual information but also haptic information, and consequently it leads that the accuracy and safety in the manipulation dramatically become better. As one of the applications of bilateral control, macro-micro bilateral control has been proposed so far. This control method intends to transmit haptic information between the different scaled objects. Therefore, operators can feel the reaction force as if they are touching the real micro or macro environment. It is effective for the manipulation where they cannot operate directly. However, most conventional researches are focused on the constant scaling gain. Considering the actual manipulation, the scaling gain should be changed arbitrary by operators in real-time. To tackle this requirement, variable scaled bilateral control is proposed, and the control system is constructed based on the effect of the order of the disturbance observer, which is experimentally investigated in this paper. The validity of the proposed method is verified by experimental results.

This paper presents interaction between a user and a smart electric wheelchair. We propose a personal mobility tool (PMT) which integrates autonomous mobile robot navigation technology with intuitive and cognitive interaction between a user and a smart wheelchair. An intuitive and noncontinuous input method to enable a user to specify a direction in which he/she wants to go is proposed. Using an acceleration sensor and a pressure sensor, a user gives direction to the PMT. Then, the PMT determines a goal position in an environmental map based on the direction. Also, to help a user interpret robot behaviors, an output interface to realize informative communication between a user and the PMT is described. In this paper, we present an improved vibrotactile interface to provide environmental information from a smart wheelchair to the user. We conducted experiments to evaluate users' performance using the output vibrotactile interface. In the experiments, users tried to detect distance and angle toward obstacles based on vibration stimuli. Through the experiments, we could confirm that the improved vibrotactile interface could improve users' performance well.

For reducing the risk of pressure sore caused by long period sitting on a wheelchair, we develop a depressurization motion assistance system which is low cost and suitable for practical use. Our developing system consists of a seating cushion which the patient sits on and four air cells which can lift or incline the seating cushion. Each air cell is actuated by small air compressor, which can drive using batteries on the wheelchair respectively, and each compressor has a pressure sensor on its body. In this paper, our key ideas are two topics. One topic is mechanical design for practical use. We realize thin mechanism which enables easy implementation to the general wheelchair. For realizing this thinly design, we develop the tilt mechanism using elasticity of acrylic resin and the controller which uses only pressure sensors for estimating its lifting height and inclination. The other topic is assistance control scheme based on the patient's depressurization operation for increasing a rehabilitation performance. For realizing the proposed control scheme, we analyze the hip depressurization operation by the nursing specialists and use its results for estimating the patient's condition. Using our system, the patient can depressurize by his own will on the general wheelchair easily. The performance of our system is verified by experiments using our prototype.

In order to provide a portable Braille display for the blind and visually impaired, a novel compact device is developed by using shape memory alloy (SMA) wires. In details, according to the ability of transition between Martensite phase and the Austenite phase, SMA can expand and shrink depending on temperature. Using movement of SMA under different temperature, six compact SMA actuators which are settled in ring-like bandage and fixed on human fingers, are vibrated to stimulate human tactile sensation. Depending on optimal displacement, these actuators can present six-dot Braille and make the blind and visually impaired get information from the device. Experimental results are shown to verify the effectiveness of the developed portable Braille display.

This paper proposes synchronized robust control for an active gait trainer. We design an active gait trainer, which composes of linkage mechanism and motors, to produce preferred gait traces for people with walking disability. The goal of this work is to simultaneously control the motors to mimic normal gaits. By finding the transfer functions of the mechanism and motors, we design robust controllers to regulate the trainer in a synchronic way. The designed controllers are implemented on a cRIO™ system for experimental verification. From the results, the proposed synchronized robust control is deemed effective.

This research focuses on the electric wheelchair controlled by Human Body Motion Interface (HBMI). HBMI uses the body motion which is caused by the voluntary motion. From our previous research, it has been confirmed that HBMI, which uses the center of weight on the pressure sensor attached on the backrest has the ability of an interface. However the problem has also remained. The velocities of each wheel have determined based on the error between initial and current position of center of weight. The error increases in the proportion to the inclination of the body. In some cases, the error doesn't increase due to the contact condition between body and backrest, even if the user leans own body. In this case, therefore, the user cannot control the wheelchair arbitrarily in spite of leaning his/her body. This paper shows the improvement to control wheelchair regardless of the amplitude of the error.

In this paper, a cooperative system for target tracking for Omnidome is presented. Omnidome is a dual-camera sensor composed of an omnidirectional camera and a Pan-Tilt-Zoom (PTZ) unit. The tracking system is based on color histogram analysis, and is triggered by a motion detector; it has been designed in order to get the best performance when performing people tracking. The system is capable of extracting information from one video source, and exploit it in the analysis of the other. This capability turns out to be particularly useful when a target tracking is started in the image provided by the PTZ camera, exploiting the information already gathered by analyzing the omnidirectional image.

Objects of different sizes were lowered from a certain height by subjects manually. Then the same objects were lowered from the same height by the same subjects with a power assist system. We then analyzed subjects' heaviness perception, load forces and objects' motion features for the manually lowered objects and compared them to that for the power-assist-lowered objects. The distinctions in perceived heaviness, load forces and motion features were proposed to use to determine an appropriate human interactive control method for power assist systems for lowering heavy objects in various industries such as manufacturing and assembly, transport and logistics etc. that may enhance human operator's interactions with the power assist systems in terms of maneuverability, safety, stability, naturalness, situational awareness, motions, haptic and tactile feelings etc.
