This paper presents the development of Robot Technology Components (RTCs) using RT-Middleware (RTM) for designing assistive robotic arms and human-machine interfaces (HMIs) that can be used by the disabled. RTM is an open software platform for a component-oriented robot system. An RTC is the basic functional unit for constructing a robot system using RTM. The interface definition for the basic functionality...
The basis of the e-learning system used in most educational institutions is a character representation by a web browser. This has caused a decrease in usability. It's user interface is not easy for beginners. Therefore, the user comes to have to study the manner of operation of the system before original study. This paper proposes the GI (Gesture Interface) as an operation method for e-learning system...
To support disabled persons with less muscle strength like muscular dystrophy patients, a single switch and a scanning menu panel is introduced to input method for the manipulator control. The iArm manipulator and its simulator are connected to evaluate the input performance. The evaluation task is the handling of pegs on the pegboard with the manipulator. Muscle dystrophy patients tested our interface...
To support disabled people with less muscle strength like muscular dystrophy patients, we are developing simple robot arm systems. In this paper, we report the improvements of the inter-face part of the system. The user can change the buttons' position on the input panel only with the single switch. The user can let the buttons on the input panel scan with single click and can select a button with...
We are developing a manipulator system in order to support disabled people with less muscle strength such as muscular dystrophy patients. Such a manipulator should have an easy interface for the users to control it. In this paper, we report on the construction of the user interface of the system using RT-middleware. RT-middleware is an open software platform for robot systems. Therefore other interface...
Electroencephalograph (EEG) recordings during right and left hand motor imagery can be used to move a cursor to a target on a computer screen. Such an EEG-based brain-computer interface (BCI) can provide a new communication channel to replace an impaired motor function. It can be used by e.g., handicap users with amyotrophic lateral sclerosis (ALS). The conventional method purposes the recognition...
Conventional research on motion recognition using surface electromyogram (SEMG) is mainly focused on how to process with the signals for pattern recognition. However, it is of much consequence to the motion recognition that measurement channels position including useful information about SEMG pattern recognition is selected. In this paper, we present two topics for the hand motion recognition system...
In this paper, we describe the human-interface equipment using surface electromyogram (SEMG) based on optimal measurement channels for each subject. In case the SEMG is used as a control signal, individual differences of SEMG are important issue to obtain high accuracy recognition of motions. To solve this problem, we propose a channel selection method of the suitable measurement channels for the...
SEMG (surface EMG) has many benefits, for example measuring SEMG is easy and a characteristic pattern of SEMG is obtained for each different movement. Therefore, SEMG that is generated by body movement is able to use as a control signal for some electric powered equipments. Our objective is the perfect control of the computer by using SEMG that is generated from forearms. In this paper, we will talk...
