Fast and accurate text entry is highly desired by elderly smartphone users. However, human factors heavily affect their experience of typing on a miniature surface. More and more applications require additional and precise typing while ambiguity arises when the 62-character alphanumeric scheme is mapped to a smartphone keyboard with fewer keys, leading to ambiguity. In this paper, we propose a novel text entry approach called PluralTap that breaks up a traditional smartphone keyboard layout and allows concurrent key tapping on different surfaces. By discretely displacing input elements PluralTap improves the speed and accuracy of text entry, enabling elderly users with more finger engagement and less finger movement. Results from our pilot study reveal that PluralTap is a more efficient approach for text entry than using existing key layouts.","PeriodicalId":140232,"journal":{"name":"Proceedings of the 10th International Conference on PErvasive Technologies Related to Assistive Environments","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129154554","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}

Innovations of new technologies, such as smartphones, offer a host of new functionalities to their users. If such mobile devices become capable of recognizing sign languages, this will open up the opportunity for offering significantly more user-friendly mobile apps to sign language users. However, in order to achieve satisfactory results, there are many challenges that must be considered and overcome, such as light conditions, background noise, processing, and energy limitations. This paper aims to cover the most recent techniques in mobile-based sign language recognition systems. We categorize existing solutions into sensors-based and vision-based, as these two categories offer distinct advantages and disadvantages. The primary focus of this literature review is on two main aspects of sign language recognition: feature detection and sign classification algorithms.","PeriodicalId":140232,"journal":{"name":"Proceedings of the 10th International Conference on PErvasive Technologies Related to Assistive Environments","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117341968","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}

This could be obtained considering either short-term or long-term changes. The aim of this study is to find long-term changes (behaviour evolution) in Activities of Daily Living (ADL) or Activities of Daily Working (ADW) of users in an Ambient Intelligence (AmI) environment. Analysis is based on introduction of a novel Human Behaviour Momentum Indicator (HBMI). Extensive experiments are conducted to investigate the effectiveness of the studied techniques on real-world datasets collected from home and office environments. To show the effectiveness of the proposed approach, results are compared with Relative Strength Index (RSI). The results show that trends in ADL or ADW can be detected and the direction of the activity's trend are predicted. In addition, the results show that our proposed technique gives a better response to changes in data more than the other technique.","PeriodicalId":140232,"journal":{"name":"Proceedings of the 10th International Conference on PErvasive Technologies Related to Assistive Environments","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114578292","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 effect, a separate model is learned to classify every sample in the test set, however, this is accomplished in an efficient manner which does not require accessing the training data repeatedly. Instead, a sparse structure is imposed on the input layer weights, which enables calculating the necessary statistics in the training phase. An application to predicting the progression of Huntington's disease from brain scans is presented. Experimental comparisons show promising results equivalent to the state of the art in machine learning with incomplete data.","PeriodicalId":140232,"journal":{"name":"Proceedings of the 10th International Conference on PErvasive Technologies Related to Assistive Environments","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123022652","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}

Dynamic Time Warping (DTW) is often used in sign language recognition to generate a frame alignment between two input signs that provides a measure of their similarity. Alignments provided by DTW may not be meaningful when the input contains periodic signs, especially when the number of periods differs between inputs. Additionally, the number of periods may change between individual signers and signs. Little work has been done to address the problem of recognizing periodic signs in the context of DTW. This work evaluates two DTW-based approaches. The first uses a newly defined periodic warping path. The second uses manual annotations to truncate periodic input to contain no more than two periods. These two methods are compared against a standard implementation of DTW. Recognition accuracy and quality of alignment are analyzed. The results motivate a need for further research in periodic sign language recognition.","PeriodicalId":140232,"journal":{"name":"Proceedings of the 10th International Conference on PErvasive Technologies Related to Assistive Environments","volume":"195 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123337271","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 this work we present a first approach which aim to integrate these elements into a Tangible User Interface (TUI) to support students with VI to learn basic Arithmetic. We have devised a first multimodal approach based on auditory feedback and tangible numbers to support an elementary school student to write, solve and present arithmetic operations. We describe our main observations, advantages and drawbacks found during an early stage experiment, we discuss the potential directions where Tangible User Interfaces can support teaching of mathematics for students with VI, and we establish concrete points for future work in this field.","PeriodicalId":140232,"journal":{"name":"Proceedings of the 10th International Conference on PErvasive Technologies Related to Assistive Environments","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134633964","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}

Since then, augmented reality (AR) applications are largely limited to prototypes. One reason might be the lack of user comprehension regarding user requirements. In order to develop a HMD-based training system for daily use, it is important to understand user demands. This paper aims at presenting a demand analysis for an industrial engine assembly line at the car manufacturer BMW Group. We describe the background of training within industries (TWI) and present extant AR-based training studies. We use the value proposition design method to analyze our customers and classify our requirements with a common quality management method, the Kano Model. We find four \"must-have\" requirements for a HMD-based training system, which are crucial for the development of a minimal viable solution. In order to familiarize assembly employees with augmented reality applications, we design a simple demonstration for the Microsoft HoloLens. Additionally, we present future research directions focusing on comprehensive user studies in real industrial environments.","PeriodicalId":140232,"journal":{"name":"Proceedings of the 10th International Conference on PErvasive Technologies Related to Assistive Environments","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133281937","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}

Within the research project ZentrAAL a comprehensive participatory approach is deployed, to achieve the goal of a user driven conceptualization, development, and evaluation process. Within this process, the modeling of the user interface and interaction, based on defined use cases is performed by means of various methods. The proposed concept contains an interaction schema that represents elements of the human -- system interface, e.g. navigation, dimensions of use cases, interaction and information elements as well as element labels depicted in one view per use case. The interaction schema acts as a communication tool during the user interaction conceptualization phase in AAL projects. First outcomes of the conceptualization of the use case focused interaction diagram are the improvement of interdisciplinary communication, easy derivation of interface prototypes, and additional point of view for stakeholders in a project.","PeriodicalId":140232,"journal":{"name":"Proceedings of the 10th International Conference on PErvasive Technologies Related to Assistive Environments","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132614875","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}
