However, blind people face difficulties in accessing these text materials. Web browsers for the visually handicapped people in the past have been limited to converting documents to Braille or speech, or extracting text and filtering. However, the human aspects of web surfing for blind people have not been adequately addressed. This paper presents an architecture of an open source, light weight web browser that makes it easy for the visually handicapped people to surf the web. The proposed architecture allows a blind person to navigate any web content through simple speech commands and voice feedback to any keyboard operation. The browser will have an integrated text extraction engine that inspects the content of the page to construct a structured representation. The internal nodes of the structure represent various levels of abstraction of the content. This helps in easy and flexible navigation of the page so as to rapidly home into objects of interest. Finally, the browser is integrated to an automatic Text-To-Speech and Text-To-Braille transliteration engine that outputs the selected text in the form of speech and/or Braille.","PeriodicalId":262830,"journal":{"name":"2010 IEEE Students Technology Symposium (TechSym)","volume":" 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116552059","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}

ICT in present form has offered to interact with the computing system in users own language. But, there are several challenges to be addressed to achieve the full advantages of ICT. One of the biggest issue is standard text input mechanism. In practice, the text input mechanism is mainly realized through the virtual keyboard. A numbers of work have been proposed to design virtual keyboard with optimum layout. So that performance of text entry can be enhanced. Still there are demand of more improvement to make an efficient text entry mechanism. In this paper, a new concept of adaptation in virtual keyboard is proposed. Our objective is to develop a user friendly interface through adaptation of key size and centroid distance between keys. As a mean of adaptation, we provide several states (keyboard) on the basis of key size and center distance between keys. Upper and lower threshold values for a performance metric of a state are defined by evaluating the states using motor movement time and searching time. If one individual user performance is in between the range of upper and lower threshold values for the keyboard then no adaptation is required. Otherwise, the keyboard is adapted according an algorithm proposed in this paper. The proposed approach is experimented with real users and results substantiate the efficacy of the approach.","PeriodicalId":262830,"journal":{"name":"2010 IEEE Students Technology Symposium (TechSym)","volume":"332 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134463376","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}

Uthayakumar","doi":"10.1109/TECHSYM.2010.5469188","DOIUrl":"https://doi.org/10.1109/TECHSYM.2010.5469188","url":null,"abstract":"Fractal Analysis is the well developed theory in the Non-linear Analysis of Biomedical Signals such as Electroen-cephalogram (EEG). EEG Biomedical signal is essentially multi scale fractal i.e., Multifractal. Therefore, quantifying the chaotic nature and complexity of the EEG Signal requires estimation of the Generalized Fractal Dimensions spectrum where the complexity means higher variability in general fractal dimension spectrum.We organize a novel technique for estimating the steepness of EEG signals from Epileptic Patients. The proposed idea is developed from the theory of Rényi Fractal Dimensions or Generalized Fractal Dimensions (GFD), which is based on the concept of generalized Rényi Entropy of a given probability distribution. The range of GFD shows the chaotic nature (ir-regularity) and complexity of the Biomedical Time Series. We estimate the steepness of EEG Fractal Time Series using the Steepness measure, which is defined from the GFD. We compare these measures for the EEG signals taken at different states and observe that there are significant differences between the values of Steepness measure for the Epileptic EEGs and Healthy EEGs. Finally we conclude that Epileptic EEGs has less complexity (less unexpected values) than the Healthy EEGs. These are the system of Multifractal techniques, which are very efficient tool in the Non-linear Analysis of Biomedical Signals to analyze, detect or predict the state of illness of the Epileptic patients.","PeriodicalId":262830,"journal":{"name":"2010 IEEE Students Technology Symposium (TechSym)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121041136","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}
