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.

Rumors can easily spread on the microblogging service Twitter in the form of retweets, which are tweets that a user has forwarded to his/her followers. This study investigated the social network characteristics of Twitter users who retweeted rumors concerning the Great East Japan Earthquake. We targeted not only the users who spread the rumor that was delivered to their timeline but also those who did not retweet the rumor. Moreover, we investigated each personal network of the user and his/her followings and followers on Twitter, including the set of connections between them. Consequently, we found that the users who spread the rumors are characterized by lower centrality (lower degree and betweenness) and lower reciprocity (fewer mutual follow relationships).

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.

With respect to collaborative physical tasks, gaze and gestures play significant roles when referring to physical objects. In video-mediated communication, however, such nonverbal cues become "ineffectual" when they are presented via a 2D monitor, making video-mediated collaborative physical tasks inefficient. This study focuses on gaze cues to support remote collaborative physical tasks using a mobile terminal and uses an eye-shaped display, "ThirdEye," a simple add-on display that represents a remote participant's gaze direction. ThirdEye is expected to be especially effective when used with mobile terminals. We investigated whether the ThirdEye’s gaze shift is effective in leading a local observer's attention toward objects in the local environment, even when ThirdEye is presented with the actual face image of a remote person. Experimental results show that ThirdEye can lead the local participant’s attention to intended objects faster than without ThirdEye.

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.

This paper proposes a new visualization method for fluctuating gazing points using future lines to assist in following subjects' gazing points. We have conducted experiments to evaluate the effectiveness of this method. From the results of the experiments, the time lag following gazing points was shortened by the method. In addition, surveys for the gazing points' followers were conducted, and results showed that future lines were considered to positively impact their tasks related to following gazing points. These results revealed that the proposed method of adding the future lines contributes to the improvement of gazing points' followability.

Touchscreens are common in personal devices as well as in public devices such as ATMs and vending machines, because they are customizable and require less mental and physical load. However, touchscreens are subject to human error and visual overload, because a touchscreen interface doesn’t have haptic clues. Furthermore, the elderly may tend to be more affected by these issues. We conducted the experiment by measuring finger movement and finger contact force while using a touchscreen, to ascertain suitable feedback from haptic clue for both the elderly(62-75 years old) and younger people(20-30years old) . The findings were as follows: The amount of finger movement and finger contact force of elderly participants were significantly more than that of the younger participants (p < 0.01). Increased finger movement was due to tremors and decreased dexterity caused by aging. Increased finger contact force was due to two reasons: first, a response to less haptic feedback than what elderly participants are accustomed to experience, such as in the operation of a mechanical button; second, an attempt to prevent an error in movement due to their tremor. In addition to the physiological measurements, interviews of the participants revealed that the reason for their differences in using ICT devices is not a lack of experience, but physiological issues, such as tremors, decreased sensation in aging. The study further confirmed that touchscreen designs should include larger buttons and text display and a haptic experience that is attuned to strong finger contact force to promote greater usability for elderly users.

Haptic feedback in current consumer game machines is limited to symmetric vibrations and impulses except for few types of controllers dedicated to certain types of games. Force display technology based on asymmetric vibration is of particular interest in enriching the feedback due to its capability of producing illusory sensations of directional forces by portable miniature vibrators. Here, we introduce a novel fishing game based on this technology. When participants approached virtual fishes displayed on a touchscreen with a contactor hung from a pinched vibrator, asymmetric vibrations were applied to the fingertips to give a sensation that the fish nibbled and pulled the string. Subjective reports collected at exhibitions confirmed that the vibration successfully induced pulling force sensations with minimum numbness. Experimental results further suggested that perceived strength of pulling force, roughness of vibration, reality as pulls of fishes, and impression of fish size can be modulated by systematically controlling the gain and frequency of the vibration, and that variations in the latter two are explained by the former two factors. Our study sheds light on the possibility of representing kinetic interactions with live creatures by portable miniature vibrators, and suggests its application to games with such interactions.

The 'body image' is a sense of ownership of our own body. Some report shows the body image is induced by the integration of cross-modal perception, such as, visual, tactile and proprioceptive perception. Other report indicates that synchronized cross-modal stimuli could induce the body image to visible object and subjects experienced that the visible object was recognizable as a part of their body. Accordingly, the development of new interface system for virtual reality is expected by using the body image. However, the body image is subjective experience and is hard to observe objectively. In this paper, we examine whether the measurement of brain activation using Near Infra-red Spectroscopy (NIRS) would able to observe the body image which is induced by cross-modal stimulation. In this experiment, the brain activation was measured around the temporal lobe to the occipital lobe, and asynchronously visual and proprioception stimuli have given to the subjects synchronously to change their body image. As a result, brain activities were observed around the Superior Temporal Sulcus (STS), the inferior parietal areas and the Extrastriate Body Area (EBA) which is reported that related to distinction of other body. Controversially, Subjects reported that they experienced the body image to the CG model displayed as visual stimuli. Our result shows there are some possibilities that the body image would be induced by some inconsistent cross-modal stimuli.

How do we interact with mechanical systems? Users command something, and the systems always accept and react it. In other words, it is a "Leader-follower" relationship. Thinking about a scene where you walk in a park with your friend, on the other hand, there are neither a definite leader nor a follower. They co-adjust the walking direction and the pace by considering each other from implicit body movements. We named the relationship that people co-adjust each other "Side-to-side relationship." In this research, we attempt to construct "Side-to-side relationship" between a human and a robot by utilizing a robot platform "Mako-no-te" that can walk hand in hand with its human partner. We conducted an experiment with three conditions; human leading condition, robot leading condition, and co-adjusting condition. As a result, the robot of the co-adjusting condition was evaluated more favorable, active, and lifelike than one of other conditions.

Flick text entry on smartphones is so popular that a majority of users prefer it to the more conventional QWERTY keyboard. Yet, the typing speed and accuracy of such text entry varies greatly depending on the individual. Focusing on eye-gaze behavior, we analyzed typing data of 33 individuals recorded with a touch logger and eye tracking data of 31 individuals recorded with a glass-type eye tracker to clarify what causes the individual variability. Correlation analysis revealed the following four findings. 1) The typing speed and the reciprocal of time interval from a release to the next landing showed a high correlation over 0.90. 2) The higher the gazing ratio at the keyboard was, the slower the typing speed and the higher the accuracy tended to be. 3) Some expert users achieved a fast typing speed and a high accuracy. 4) The majority of errors were landing errors to adjacent keys. On the basis of these findings, we propose a keyboard layout that considers eye gaze.
