As the results show special haptic feedbacks like amplitude changes, rotary changes or blocks at the end of the torque function are recognized very well. The results also show that haptic feedbacks can be used in combination with visual displays to transmit information. The transmission of information through the haptic and visual perception channel is even better than the purely visual transmission. But this statement must be backed up by further studies in order to show that the haptic transmission of information to the user via a central control element leads to a reduction of operating time, visual distraction and cognitive stress in difficult tasks.All in all, this approach allows innovative interfaces so that the usability of products can be improved and the operational safety can be increased.","PeriodicalId":389707,"journal":{"name":"Advances in Ergonomics In Design, Usability and Special Populations: Part I","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133232045","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}

Yasukouchi","doi":"10.54941/ahfe100781","DOIUrl":"https://doi.org/10.54941/ahfe100781","url":null,"abstract":"In order to find a stimulus that improves tracking operation accuracy, low-amplitude oscillation was applied to two types of control device (a grip type and a steering wheel) in a tracking simulation. The tracking operation was as follows: The target cursor moves side to side at a fixed velocity. Subjects control the device with the aim of making the control cursor follow the target cursor. The velocity of the target cursor was set at either a low or a high velocity. The separation between the target cursor and the control cursor (the tracking error) was used to evaluate the task performance. Three oscillation stimuli were used: sin waves of 10, 20, and 40 Hz, each at three different amplitude levels. A no-stimulus experiment was used as a control. In the slow cursor, the tracking error was significantly reduced with the 20 Hz oscillation compared to the control (p\u0000 < 0.05). In the fast cursor, no stimulus improved the accuracy of the tracking operation. On the other hand, the tracking error was significantly increased with the 10 Hz oscillation in comparison to the control (p\u0000 < 0.01). These results suggest that an oscillation of 20 Hz could improve the accuracy of tracking in the slow target. The oscillation of 20 Hz could affect the protagonistic muscles of the operation, and could improve sensitivity of the muscle spindles by stochastic resonance phenomenon. As a result, the devices were operated more accurately and the tracking errors were decreased.\u0000","PeriodicalId":389707,"journal":{"name":"Advances in Ergonomics In Design, Usability and Special Populations: Part I","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133674735","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}

The project chosen to validate this research aims to optimize endoskeleton prosthesis for lower limb and therefore the quality of life for amputees. In the first methodological moment, i.e. analysis, several variables related to shortcomings of the current products and possible improvements were identified through interaction with users. With these data it is hoped to surpass the kind of devices limited to reproduce a walking cycle and obtain effective solutions both for the initial phase of rehabilitation as for the further active life of the patient.","PeriodicalId":389707,"journal":{"name":"Advances in Ergonomics In Design, Usability and Special Populations: Part I","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130988232","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}

For this important task of design, greater use must be made of information and computing tools so as to draw up more innovative designs. Adapting environments from the point of view of the dimensions, of computerization, of the physical space and of furniture in order make homes comfortable, safe and suitable for the elderly, as become of great importance today, because recent studies reveal that every year in our cities, the number of elderly people has been increasing. The object of this paper is to present a proposal for a dwelling with multiple functions, all of them concentrated on computer systems that meet the needs and assist this age group in coping with their limitations. Under the rules of Living with Gerontology arising from old age, adapting a new space for an accessible Loft is, according to the latest trends, a new concept of housing that aims to offer the elderly, an ever-growing and more active segment of society, a setting that is more appropriate and a safer life which has quality and dignity.","PeriodicalId":389707,"journal":{"name":"Advances in Ergonomics In Design, Usability and Special Populations: Part I","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133685066","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}
