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.

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.

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.

Recently wearable electroencephalography(EEG) device enables us to mea sure brain activities during moving. However, EEG data include noise caused by movement when participants move. Therefore, it is a significant problem to reduce the noise in order to measure brain activities during moving. In this paper, we focused on the workload estimation from auditory steady state response during walking. We compared the noise reduction performance of some kinds of blind source separation methods.

This study investigated how pedagogical conversational agents can facilitate learner-learner collaborative learning during a knowledge integration task. The study focused on how knowledge integration activity can be facilitated by using multiple Pedagogical Conversational Agents (PCAs). The current study investigated the effective design of the PCA using the modality such as using gaze gestures along with the verbal facilitation prompts. In a controlled experiment, dyads were accompanied by multiple PCAs programmed to facilitate explanation activities in a knowledge integrating task. Two eye-trackers were used to detect learning process of leaners who used different type of knowledge and perspective. The results show that learners who received facilitation from the PCAs about integrating different perspectives performed better on the task, and if they received gaze gestures, they tended to focus on the relationship of different knowledge as well. Additional results on eye-tracking analysis show that learners performed better when they focused at their partner ’s different knowledge after looking at the PCAs'’ gaze. These results provide new implications on designing learning support systems and shows how embodied information such as gaze gestures of PCAs may play an important role in collaborative learning.

Digital Fabrication has become familiar to ordinary people, but making data for digital tools such as a Laser cutter using CAD is difficult for beginners. We developed an easy to learn and accurate CAD interface for tablet “Drafter” based on stationary metaphor. We compared Drafter and present CADs by experiments consisting of both drawing part and questionnaire part. The drawing part showed that Drafter is easier to learn than present CADs, has the same accuracy as present CADs. The questionnaire part showed that Drafter has the same accuracy as present CADs, and is better at usability than present CADs.
