A user survey on Braille transcription and audio recording services for the blind was conducted. The use rates of these two services were both more than 40%. The top two providers of these services were either of Braille transcription or audio recording circles and Braille libraries. Nearly half of the users were using these services at a frequency of once in a few months. The problems faced when using these services were long waiting times for the books to be translated. The difference between these two services were documents to be translated and the frequency: Braille transcription service was used mostly for work-related documents, product manuals, music materials, and technical books whereas audio recording service was used for novels, technical books, magazines, and non-fictions: A certain amount of people were using audio recoding service more frequently, once in a week to a few times a month, than Braille transcription service.

Disuencies in spontaneous speech is often regarded as speaker's speech error, and it is often explained by attributing it to the internal mechanism of the speaker. On the other hand, it can also be regarded that disuencies were created as a result of the interaction between the speaker and the hearer. From this point of view, an utterance generation system “Talking-Ally” has been constructed. In this study, the objective is to explore the factors that create disuencies by a constructive approach. In particular, it focuses on the conversation adjustment function related to maintaining the conversational situation when the hearer's eye-gaze deviates from the conversation. First, we constructed a model to adjust the utterance strategies while adapting it to the hearer, then conducted an interaction experiment by using this model. And we discussed how disuencies of utterances can work.

In an evacuation behavior analysis, records of behavior such as straying are dependent on participants' memory. Therefore, there is a loss of some of behavior records. In this research, we propose pair-testing method for supplementing records. A participant pair with an observer and records the behavior of participant. As a result of evacuation experiment, the behavior of participants was supplemented by the observer by 47.5%. It is expected that evacuation behavior will be verified from the relationship between these behavior data and context-dependent data.

Nowadays, Information and Communications Technology (ICT) makes rapid progress in our community life and healthcare support system. Our objective was to explore the effect of tele-rehabilitation on memory impairment after traumatic brain injury. Studies about tele-rehabilitation on memory in adults with traumatic brain injury were reviewed. Four database searches were conducted: MEDLINE, Cochrane Library, CINAHL, and PsycINFO. Of the 523 studies identified in the search, 8 studies (including 2 RCTs) met the inclusion criteria, which involved 207 participants. There were 12 kinds of remote intervention: television assisted controlled prompting, Google Calendar, spaced retrieval training as errorless learning, and so on. A common evaluation index; Community Integration Questionnaire (CIQ) was conducted in two studies. Results from several studies indicated that remote interventions on memory impairment improve the proportion of prospective intentions completed in the patients’ daily life. Further research and meta-analysis are needed based on RCTs.

Along with the increase of nuclear families and the aging society, the social isolation of elderly people is becoming a big issue. Social robots are being regarded as suitable interfaces to support these elderly people to communicate with others (e.g. family members). In robot-mediated communication, it can be expected that asynchronous messaging functions will cope with differences in life styles between different generations, and that message inputs can be facilitated by natural language dialogue functions. Eliciting self-disclosure from elderly people by utilizing such robots is important to draw out social support from other people. In this study, the following three research questions were examined with the aim of exploring requirements for robots to encourage elderly people'’s self-disclosure. First, using a self-disclosure scale, we examined topics that were encouraged to disclose from elderly speakers by an intermediary robot. Secondly, we investigated the difference between social attributes (robot-specific traits and characteristics) of two kinds of robots with different behaviors. Last, we investigated the relationship between the robot’'s social attributes and self-disclosure from these two independent data.

With the development of internet technology, people can share knowledge through Q&A websites anytime and anywhere. However, two types of barriers between the questioners and respondents make knowledge sharing difficult: 1) lack of trust for other users, 2) an arrogant or negative attitude exhibited by the questioners. We conducted an experiment to evaluate the effect of the virtual agent for lowing these barriers with two characteristics: 1) similar profile to users, good appearance and affable personality for users, 2) positive attitude and reaction. The results indicate that the virtual agent can improve the users’ motivation to answer questions.

Previous studies of the recognition process of self-attribution conducted that it is mainly caused by congruence between visual and proprioceptive information, and congruence between visual information and prediction from motor commands. However, they did not declare which congruence acts the primary role in the process during the voluntary movements. We conducted a user study that distinguishes proprioceptive information and prediction from motor commands by displaying modified images of the subjects’ hands in various rotation angles, that introduced the conflict between visual and proprioceptive information. The hand motion of the subjects was restricted so that they could predict the visual motion of the images of their hands by the motor command even while the images were rotated. The result indicates that the prediction of the motion plays a primary role in the recognition process of self-attribution, and this predictability depends on the motion pattern and the appearance of the hand images.

In this paper, we propose a support system for substrate manufacturing workers. This system provides operation instructions on and around a substrate with projection mapping. The purpose of this system is to enable workers to produce substrates faster and more precisely in a product line which many kinds of substrates are produced. The examples of projected instructions are kinds of parts, number of parts and positions to insert parts. The projected instructions from our system change with time. Workers are required to produce a substrate by following the changing instructions. This process is expected to provide easy and rhythmical instructions for achieving faster and more precise manufacturing. To evaluate our system, we have applied the system for six months under actual product circumstance in the factory. The results show that our system reduces 12% of production time without producing reject products. We believe that this is a valuable study case that shows the effects of superimposed information in an actual product line on a long term basis.

In UX designing, we sometimes propose a new concept product or service, focusing on user experience value. In this case, it is desirable to conduct concept evaluation at an early stage to confirm the direction of development. However, the method to reasonably conduct a concept test at a stage when the product or service is not concrete enough remains unclear. In this study, we analyzed the effect of results from the differences in the expressions of the following 3 concept sentences: (A) expression showing only the experience value; (B) expression with usage scene in addition to the experience value; and (C) expression with function in addition to the experience value. As a result, we found that A could reasonably evaluate “the degree of matching the needs” and “novelty”, and that C could reasonably evaluate “sympathy”. In this study, therefore, we suggest a two-stage concept test method in which we first present only the experience value to evaluate the degree of matching the needs and then present the usage scene to evaluate sympathy.
