    The internet has been developing by leaps and bounds. And, the amount of information put on the internet has been increasing in great quantities. Therefore, the probability of information being concealed has been increasing. As a result, the following problems have arisen, i)It is difficult for users to retrieve necessary information. ii)Users must retrieve the necessary information by going through long lists of a huge amount of information. In this paper, a model which predicts the satisfaction index of users regarding information retrieval and contents listing methods was created on the basis of user's face sheets. This model was calculated based on the quantification method. As a result, information retrieval and contents listing methods suitable for users can be offered.

    The visually impaired encounters problems when reading a document through a speech synthesizer. One of these problems is that it takes long time to read a document from top to tail, and the other problem is that he can not understand the position where he read. This paper describes an improved speech representation techniques by using both one-dimensional sound source and skipping-over function. An experiment shows that the proposed method could reduce total speech output time by skipping over unimportant texts, and that soundsource-based position prediction techniques was effective for users.

    The Telecommunications Advancement Organization (TAO) of Japan has initiated a project in which electronically available text of TV news programs is summarized and synchronized with the speech and video automatically, then superimposed on the original programs for the benefit of the hearing impaired people in Japan. The project started in 1996 and will end in 2001. This report describes the recent results of our research for technology of producing closed captions for TV programs, especially production of various closed-captions for testing and preliminary assessment of caption display methods.

    In the near future, we will be able to use videophone with MPEG4 technology. Videophone is very useful to deaf people in telecommunication. But these parameters are not adapted to sign language conversation. In this paper, we investigated the relation between preference in videophone quality and MPEG4 parameters in telecommunication with sign language conversation.

  • Basic Considerations regarding Remote Sign Language Interpretation of Lectures

    Recently it has become possible for users in remote locations to communicate via sign language using video phones and videoconferencing systems. In the future, it appears likely that these technologies will make it possible to provide remote sign language interpretation services. In actually attempting sign language interpretation of a lecture from a remote location, however, critical problems must be taken in account, besides the issue of video quality, picture quality and refresh rate, that is currently being examined. With our actual classes we are conducting mock trials of remote-location sign language interpretation, and have studied the likelihood of such problems arising.

    This paper describes a communication method with vibration moters on a wrist for blind and deaf persons. First, we examine the relationship between the arrangement of six vibration moters and the vibration conditions. Next, we make clear vibration method (moter vibrating time, moter stopping time, etc.), that we can communicate the information by vibration moter satisfactory. From the result, we have found that the information is expressed by 10 kinds of figure, and the figure is representd by a row of vibration pulse. In addition, we make clear an interval of row of pulse and amount of figure communication. We confirm that we can communicate up to five figures by this method with the accuracy of 95%.

    Generally, blind people, in particular the congenitally blind, find it difficulty to understand their surroundings. To help them, the computer assisted instruction (CAI) system which gives the blind spatial awareness has already been developed. We have added a task to expand the range of spatial awareness covered by the system. In the task, a user walks around a room where objects are set, and understand the spatial arrangement of the objects. The user arranges blocks on a board to represent the memorized spatial arrangement. Then the system evaluates the block arrangement and outputs the result or correction by synthesized speech. We report the system detail, the task and the result of experiment for blindfolded sighted children by using the system.

    We have been studying on the Computerized Kohs Block Design TEST (CKBD-TEST) for the evaluation of mental capability of the severely physically disabled who don't have enough linguistic skill to write and speak. A developed CKBD-TEST in the first stage of our studies has 24 types of surfaces which are obtained by the rotation of a block. From the result of clinical testing, there are some differences in difficulties between CKBD-TEST and general KBD-TEST. In this paper, a newly developed CKBD-TEST with rotation function is described. The result of clinical testing of the new CKBD-TEST reveals that these difficulties might be caused by the difference of testing procedures between CKBD-TEST and general KBD-TEST.

    Row-column scanning, manipulated by one or two special switches, is used for the severely motor disabled. It is desired to reduce switch activations for input letters. In this paper, row-column scanning with an adaptive letter prediction mechanism is described, then it's performance is evaluated by simulation. It is shown that this method is far superior to that of simple row-column scanning, and equal to or slightly better than that of frequency ordered row-column scanning, Huffman coding, both are non-adaptive and using a priori information, and dynamic Huffman coding.

    A new input-output equipment to computer system was developed which gives an impetus to use of information-transmission equipment for physical disabled. From last year on, we experimented on the movements of key-input for disabled, and with evaluation of the time-parameter which controls key-input by statistical approach, we confirmed the validity to assign the unique value for each kind person of obstacle. And we considered the other elements which controls the key-input, and fixed on the the Decision-form.

    We have developed a new "Input Interface Switch" for Amyotrophic Lateral Sclerosis. We sent out questionnaires to nurses and attendants who look after "Ability Daily Living" at the specialized neurological hospital in Japan. The switch is based on the results of these questionnaries, and is made up of Fiberoptic Sensors, Amplifiers, and Controllers. It is designed to send out signals if it separates from the user's body.

    We have developed eye gaze communication system for the people with severe physical disabilities (e.g. progressive muscular dystrophy amyotrophic lateral sclerosis, etc.). With this system the operator doesn't have to wear sensors or devices to measure direction of eye sight. The eye gaze point is displayed on the communication screen and gazed character is emphasized as a feed back. Simple word processing soft wear is provided and the operator can pick up desired characters continuously by gazing at them one by one for a few seconds. Evaluating on this system, the operator can communication faster than scanning communication aids.
