The benefits of regular exercise affect a person’s gait, shoulder function as well as head and body strength. This paper presents a new study of gesture-based communication by using arm swing as a gestural input command applied to any digital device used by persons aged 21–50 years of age during their workday. In five difference occupations, i.e., student, lecturer, office workers, designer and industrial worker, with different routine tasks were studied. The sampling comprised 30 participants, 6 persons representing each occupation. Data were collected through focus groups. The objective of this study is to provide possibilities to integrate proper user experience of gesture-based communication toward an arm-swing input device onto participants’ routine activities. It is believed this research can have a significant impact on quality on human daily lives. A part of user experience methodology, like a field experiment, is applied to provoke participants to follow the correct sequence case by case. This paper adopts user experience measurement for this qualitative research approach. A proper user experience occurs when one understands how strength and weakness are affected by gestural input. An input gesture, feedback, system and output can then be mapped together into a complete scenario of a person’s daily life. Each participant is encouraged to raise various ideas on how he/she accesses technology rather than on how technologies allow them to access information. Based on the experimental results, this paper will then discuss the possible tasks performed in the five occupations in which an arm-swing input gesture is integrated. The influence of this integration into the participants’ daily activities presents confirmation of a preferable wearable input device for all focus groups. This wearable input device can then be integrated into activities without any interruption in a person’s main actions.</p></div>","PeriodicalId":100147,"journal":{"name":"Augmented Human Research","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s41133-019-0013-6","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50044069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both virtual bodies of self and target are generated using digital human modeling from statistical data, and the animation of self-body is motion-captured while the target body is moved using a weighted inverse kinematics approach with end effectors on the hands and feet.

We investigated how vibrotactile stimulation given to the forehead could be used to cue gaze direction. We built a vibrotactile headband with an array of six actuators that presented short, tap-like cues. In the first experiment, the participant was instructed to look at the point on a horizontal line that they thought the vibrotactile cue was pointing to. Analysis of the participant’s gaze points showed that for the majority there were statistically significant differences between cues from different actuators. This indicated that the six actuators could successfully direct the participant’s gaze to different areas of the visual field. In addition, vibrotactile cueing of gaze direction could be used for directing visual attention and providing navigation cues with wearable headbands. To strengthen our findings, we investigated how effective the vibrotactile stimulation would be to cue gaze direction in a visual search task. Participant’s were asked to find a deviant shape (a target) from a display full of simple shapes. The vibrotactile cueing implemented with the headband device was used to inform the participants of the approximate horizontal position of the target in three different experimental conditions. In the most informative condition, six actuators were used to inform the participant of the horizontal area where the target would be found, in the second condition two actuators were used to inform the participant of the target side on the display (left or right), and in the least informative condition no directional information was given. Analysis of the trial completion times showed that there were statistically significant differences between the least informative condition and the two other conditions. However, we did not find significant differences in trial completion times between the two conditions where information of the target location was given. This indicated that while the actuators could successfully direct the participant’s attention to different areas of the visual field to help in the search task, the simple approach of just adding actuators and dividing the visual field to more sub-areas did not improve the results. The findings of this study showed that while there is potential in using vibrotactile cueing of gaze direction, more research is needed to fully exploit it.</p></div>","PeriodicalId":100147,"journal":{"name":"Augmented Human Research","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s41133-017-0008-0","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50052168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular and in contrast to most other scientific disciplines, sports science research has been characterized by comparatively little effort investment in the development of phenomenological models. Practical applications of such models aimed at assisting trainees or sports professionals more generally remain nonexistent. The present paper aims at addressing this gap. We adopt a recently proposed mathematical model of neuromuscular engagement and adaptation, and develop around it an algorithmic framework which allows it to be employed in actual training program design and monitoring by resistance training practitioners (coaches or athletes). We first show how training performance characteristics can be extracted from video sequences, effortlessly and with minimal human input, using computer vision. The extracted characteristics are then used to fit the adopted model i.e. to estimate the values of its free parameters, from differential equations of motion in what is usually termed the inverse dynamics problem. A computer simulation of training bouts using the estimated (and hence athlete specific) model is used to predict the effected adaptation and with it the expected changes in future performance capabilities. Lastly we describe a proof-of-concept software tool we developed which allows the practitioner to manipulate training parameters and immediately see their effect on predicted adaptation (again, on an athlete specific basis). Thus, this work presents a holistic view of the monitoring–assessment–adjustment loop which lies at the centre of successful coaching. By bridging the gap between theoretical and applied aspects of sports science, the present contribution highlights the potential of mathematical and computational modelling in this field and serves to encourage further research focus in this direction.</p></div>","PeriodicalId":100147,"journal":{"name":"Augmented Human Research","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s41133-017-0007-1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50103270","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To overcome these problems, we attempted to introduce a new approach for measuring affective states, based on the combination of the day reconstruction method and the measurement of physiological stress levels by a wristband-type wearable device. As the indicator of physiological stress levels, we used heart rate variability calculated from the data recorded by the device. We examined the interpretability of the physiological stress level as a substitute for affective states by applying this combinational approach to an aging and depopulating village in Japan, because the well-being of the residents in such areas is a matter of public concern. As a result, we could depict the sources of affective well-being and the physiological stressors in the village. We also found a reasonable, but weak, correlation between the scores of affective states and the indicator of physiological stress levels.
