These are used in combination with an RGB‐D sensor and a simplified SLAM algorithm to develop a framework for navigation assistance suitable for the blind and low‐vision users.Findings – It was found that signage detection cannot only help a blind user to find a location, but can also be used to give accurate orientation and location information to guide the user navigating a complex environment. The combination of visual nouns for orientation and RGB‐D sensing for traversable path finding can be one of the cost‐effective solutions for navigation assistance for blind and lo...","PeriodicalId":89962,"journal":{"name":"Journal of assistive technologies","volume":"7 1","pages":"118-130"},"PeriodicalIF":0.0,"publicationDate":"2013-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1108/17549451311328790","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"62161486","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 system works by adding touch sensors that trigger audio tags to tactile controls. The touch sensors trigger the audio tags before the control is activated. Design/methodology/approach – The paper describes how several devices were enhanced with the new technology, tested and evaluated. Initial informational interviewing with visually impaired people was followed by user studies with blindfolded but visually able people. A final evaluation of the system was conducted by a visually impaired group. Findings – This paper shows that the technology is of benefit to a visually impaired user when using a complex unfamiliar device. Originality/value – This novel application of touch sensors coupled with audio tags has the potential to benefit visually impaired people. This technology can easily be incorporated into commercial devices.

We have also surveyed some systems for use with dyslexic learners currently in use and have compared them on the basis of number of barriers, technological innovation, age group and fostering. Findings – Dyslexic learners are characterized by slow learning, poor handwriting, poor spelling skills and difficulties in planning, organizing, revising and editing texts; technology plays a major role in the educational environment; it has become crucial in impacting knowledge across the globe; and open research issues and challenges that have to be addressed in the design of the current dyslexic system have been presented in detail.

According to the two surveys on user needs and user experiences with existing VUI systems at the stage of the prototype design, the target platforms, and target applications are determined. Furthermore, a set of basic words is selected by the prospective users, which enables the system to be not only custom designed for dysarthric speakers but also individualized for each user.

Hypotheses examined whether the use of graphic symbols help 3. 5-5 year-old students to increase the number of questions and the number of words in the questions asked for a particular subject. Design/methodology/approach – Following an experimental design approach, an experimental (EG) and a control group (CG) of children, matched to age (4:2) and to their ability to make questions (pre-test), attended an instructional programme. The EG used Widgit Symbols and the CG the traditional methods used by educators to teach questioning. Data collection involved pre and post oral assessment tests, which measured the number of questions and the length of questions in role play activities. Findings – Findings of the study showed that symbols have positively affected children’s ability to make questions. The EG scored higher than the CG on variables examined, and the within groups improvement (pre to post test) was again higher for the EG. Research limitations/implications – The paper discusses some possibilities of a lengthier implementation of the use of symbols and their effect on language acquisition. Practical implications – The study raises some considerations about the development of new teaching methodologies with the use of symbols and Information Communication Technology to enhance language development and maximize learning for all learners.
