To support the idea of universal services (one stop for all), the government has been planning to develop an e-Government system that will provide all major services and official information on the internet (web based system). Since the issues to provide accessibilities for person with disabilities (pwds) become a major concern for modern information society. Accessibility becomes an important feature for all government websites, especially for websites that service to pwds. The preliminary survey on the government websites in 2003 showed a remarkably low standard of web accessibilities. Only 3 out of 267 government websites passed the test of World Wide Web Consortium (W3C) guidelines on web accessibility. To support the promotion of web accessibility in Thailand, Assistive Technology Center (ASTEC) plays the important roles to provide necessary information and tools of web accessibility development for the government. This paper presents our works from the past to the current state of the project including: a development of the national guideline on web accessibility that is agreeable among web developers, a development of web accessibility evaluation tool, and a preparation of policy planning to promote web accessibility in Thailand.","PeriodicalId":241320,"journal":{"name":"International Convention on Rehabilitation Engineering & Assistive Technology","volume":"2014 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128111793","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}

Face moving can control mouse pointing position in any directions on a computer screen. Eyes blinking can click a mouse: left or right. However, if face moving is too fast, the tool may not detect the right direction. Another problem, un-intention of eye blinking may make a mouse click.","PeriodicalId":241320,"journal":{"name":"International Convention on Rehabilitation Engineering & Assistive Technology","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131463605","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}

Along with the hardware development of the PSU Braille computer, the group has also developed translation software with Thai and English processing capability. The work in this paper also includes the integration of all translation programs, i.e. English, Thai, Math, Chemistry to Braille and vice versa, using the Extensive Markup Language (XML) and Braille Computer Code. In addition, the XML technology has also been applied extensively for classifying and collecting documents in the system.","PeriodicalId":241320,"journal":{"name":"International Convention on Rehabilitation Engineering & Assistive Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129460385","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 order to assist the patient to return to his/her normal way of life as much as possible, a rehabilitation program is tailored for the patient. However, before any rehabilitation program could be given to the patient, assessment tests has to be carried out. Motor function assessments are basically assessment of human muscle strength. The objective of this project is to design and develop a quantifiable assessment device for stroke patients. For collection of data, the subject was asked to perform a muscle assessment which is a combination of isoinertial and isokinetic muscle assessment. The motion was then captured and analysed using a 2-Dimensional kinematic video analysis. The result of the assessment reveals that the fluidity of the motion is shown clearly. The data of two different set of performances could also be readily differentiated, albeit the progress of the patient may be just a little. This has shown that the assessment designed in this project for a stroke patient through kinematic analysis is able to assess the ability of the patient. However, this assessment has been carried out on one muscle group and no actual stroke patients are involved. The assessment could be conducted on stroke patients to ensure there is a direct correlation between assessment and clinical measures.","PeriodicalId":241320,"journal":{"name":"International Convention on Rehabilitation Engineering & Assistive Technology","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121492918","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 prevent foot slap after initial contact, the ankle joint needs to be actively controlled to minimize forefoot collision with the ground. During late stance, the ankle joint also needs to be controlled to provide toe clearance and to help push-off. 3D gait analyses were performed on a hemiplegic patient under three different gait conditions: gait without AFO(NAFO), gait with the conventional hinged AFO without controlling ankle joint (HAFO), and gait with the developed AFO(AAFO). Results showed that AAFO could prevent not only foot drop by the proper plantarflexion during loading response but also toe drag by sufficient amount of plantarflexion in pre-swing and reasonable dorsiflexion during swing phase, enhancing all temporal gait parameters. The present results indicated that the developed AAFO might have more clinical benefits to treat foot drop and toe drag in hemiplegic patients, comparing with conventional AFOs.","PeriodicalId":241320,"journal":{"name":"International Convention on Rehabilitation Engineering & Assistive Technology","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133049057","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 discrete drug head contains embedded electrodes which are energized using an inbuilt stimulator of the applicator.
