The objective of this study is to investigate the difference between the standard 'design guideline' in barrier free laws for the disabled and the disabled's real experience in public convenient facilities. It is mainly focused on accessibility by the disabled people who use an electric motion wheel chair, a wheel chair and crutches as well as a visual impaired person in the public resident centers. For this purpose, four resident centers in Busan have been selected as the objects of investigation. We observed and video recorded the disabled people with various handicaps to access and use facilities in four resident centers, and interviewed them afterwards. We found out problems from the perspective of the disabled and figured out the difference between barrier free laws and the disabled's real experience. The research result is as follows. First, it is important to make the arrangement of public convenient facilities according to the flow of the user's movements. Second, it is necessary to provide better conditions for the disabled to access the public toilet easily and conveniently. Third, it is essential for public convenient facilities to be more strictly controlled by regulations. Fourth, we need to make better standards that could reflect real experiences of various disabled users. Fifth, we need to keep providing the best follow-up service for the disabled in terms of using public convenient facilities safely. This study can contribute for designers to understand specific users through their experiences and suggest improvement ideas for better public convenient Facilities.

This study compares hand-based interfaces to improve a user's virtual reality (VR) presence by enhancing user immersion in VR interactions. To provide an immersive experience, in which users can more directly control the virtual environment and objects within that environment using their hands and, to simultaneously minimize the device burden on users using immersive VR systems, we designed two experimental interfaces (hand motion recognition sensor- and controller-based interactions). Hand motion recognition sensor-based interaction reflects accurate hand movements, direct gestures, and motion representations in the virtual environment, and it does not require using a device in addition to the VR head mounted display (HMD). Controller-based interaction designs a generalized interface that maps the gesture to the controller's key for easy access to the controller provided with the VR HMD. The comparative experiments in this study confirm the convenience and intuitiveness of VR interactions using the user's hand.

TheReviser is a digital document revision application on a projection display, which allows us to interact a digital document with the same gestures used for paper documents revision. To enable these interactions, TheReviser should detect foreground objects such as hands or pens on a projection display, and should spot and recognize gesture commands from continuous movements of a user. To detect foreground objects from a complex background in various lighting conditions, we perform geometry and color calibration between a captured image and a frame buffer image. TheReviser uses an HMM-based gesture recognition method Experimental results show that the proposed application recognizes user's gestures on average 93.22% in test gesture sequences.

To enhance the educational effect of Multi-Joint Robot have to easily develop motion through the control software. The traditional way of development technique for multi-joint robot is educated with very complicated implementation, but our motion creation tool can be possible to do the creative activity for controling robot movements with ease. This paper mentions to develop the motion creation tool for easily and quickly programming the motion control of multi-joint robot on the educational program. With this tool we easily and exactly provide the education of robot program. In this paper, our suggested tool could not only evade the traditional way of a complicated control program using programming languages but also control easier the robot than the GUI(Graphic User Interface) programming centered on the user's convenience. Additionally, the robot motion's implementation is possible applied with microprocessor experimental equipment educationally to practical use.

This paper presents the development of a robotic system for rehabilitation of the trunk's ability to maintain postural control under different balance conditions. The system, developed with extensive input from rehabilitation and biomedical engineering experts, consists of a seat mounted on a robotic mechanism capable of moving it with four degrees of freedom (3 rotational and 1 translational). The seat surface has built in instrumentation to gauge the movements of the user's center of pressure (COP) and it can be moved either to track the movements of the COP or according to operator given commands. The system allows two types of leg support. A ground mounted footrest allows participation of legs in postural control while a seat connected footrest constrains the leg movement and limits their involvement in postural control. The design evolution over several prototypes is presented and computer aided structural analysis is used to determine the feasibility of the designed components. The system is pilot tested by a stroke patient and is determined to have potential for use as a trunk rehabilitation tool. Future works involve more detailed studies to evaluate the effects of using this system and to determine its efficacy as a rehabilitation tool.

With the recent advance in the performance of mobile phones, many effective interfaces for them have been proposed. This paper implements a hand-gesture-and-vision-based interface on a mobile phone. This paper assumes natural interaction scenario when user holds a mobile phone in a hand and sees the other hand's palm through mobile phone's camera. Then, a virtual object is rendered on his/her palm and reacts to hand and finger movements. Since the implemented interface is based on hand familiar to humans and does not require any additional sensors or markers, user freely interacts with the virtual object anytime and anywhere without any training. The implemented interface worked at 5 fps on mobile phone (Galaxy S2 having a dual-core processor).

An example of functional army's training wear was developed with careful considerations given to the actual user. Three steps of a functional clothing design process were followed in the design procedure. First, information on the adequacy of the current army's training wear was collected by interviews with 192 persons. Second, the current design and construction of the training wear was altered to meet the user's need from the result of the interview. Third, the performance of the newly designed army's training wear was evaluated for their effectiveness in several aspects such as conditions of the microclimate within clothing, metabolic rate, garment pressure during arm movements and appearance during body motions.

We developed a communication device for person with serious disability to use slight movement. This device is developed mainly for patients suffering from ALS or a cerebral infarction. They often have communication difficulty because of deterioration of muscle functions. A feature of this device is that slight movements of user's finger, eyes or lips can be detected by using a vision sensor. Due to the features of the vision sensor, it is quite easy even for person with serious disability to use a communication device. By the field test it is confirmed that the vision sensors have superior performances as an input device for communication device. Experiments to use an EMG (electromyography) sensor and a rotary sensor are also tested to compare the performances.

The origin of Uchida is strictly avant-garde and carries a social dimension. The work is a challenge to consumption-oriented mass production, a revolt against intrusive one-way communication, and an aversion to oppressive politics. Such a spirit led to a rare communication design that was created in collabolation with the user and designer, both relating to each other's senses of touch and in the same familiar plane. He first began by focusing on the physical movements of objects in order to achieve maximum comfort and lightness. From the beginning, He avoided strong, sturdy solids, and favored the faint, transitory and vulnerable. He choose the pursue "furniture with delicate lines", "to create darkness by layering shadows", all of which are extremely unique and resulted in designs that have a profound presence. Uchida gives various meanings and functions to the grid. This activities and philosophy of Uchida Shigeru influenced on the interior design.the interior design.
