The input strategy is based on tiny intentional contractions of a single muscle of choice (requiring a minimum of physical contribution only) which are used as \"selection marker\" in the context of scanning. The first application turns the PC into a Universal Remote Control (URC), while the second one is a Text-To-Speech (TTS) module. A simple experiment requesting the speed of the scanning scheme shows that the theoretical concept really works and that it therefore has the potential of being of great help for its target population.","PeriodicalId":241320,"journal":{"name":"International Convention on Rehabilitation Engineering & Assistive Technology","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117234405","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}

If the elderly could get help immediately after the fall, the severity of the injury could be reduced. Also, it results in decreasing the rate of death and the medical cost. This paper presents a fall detection algorithm based on the threshold value of the maximum peak resultant acceleration to classify falls and Activity of Daily Live (ADL). Two types of the experiments were investigated. Type A) ten young subjects performed both falls and ADL. Type B) ten young subjects performed falls whereas ten elderly subjects performed ADL. In the experiment, tri-axial accelerometer was mounted on the trunk. There were four categories of falls: forward fall, backward fall, left and right side fall and six categories of ADL: sit-stand, stand-sit, sit-lie, lie-sit, bend down, and walking 2 m. For the threshold of the maximum peak resultant acceleration at 1.9g, falls could be distinguished from ADL with 100% sensitivity in both Type A and B while specificity for Type A and B were 96.11% and 98.33%, respectively. Results indicate that the trend in classification of fall from ADL in the elderly could gain the increase in error. Therefore, more sophisticated algorithms for the classification of fall from ADL in the elderly are needed to improve performance of detection.","PeriodicalId":241320,"journal":{"name":"International Convention on Rehabilitation Engineering & Assistive Technology","volume":"210 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115769690","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 in this work can find obstacles applying the depth discontinuities Pixel-to-Pixel (P2P) stereo algorithm which is one of the Intensity-based Stereo Matching (ISM) techniques in stereo vision that can find objects with featureless surface such as whiteboard, door, etc. However, the ISM technique is time consuming and not fast enough for real-time usage. Applying parallel computing using Message Passing Interface (MPI) helps reduce the computing time and enables realtime usage. In this work, we estimate the distance between objects and the visually impaired by applying the V-disparity. Our system can accurately detect objects within the range of 5 meters using 12-centimeter based-line low-cost webcams.","PeriodicalId":241320,"journal":{"name":"International Convention on Rehabilitation Engineering & Assistive Technology","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116606433","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 situation is even worse for those students with visual impairment who have integrated themselves into mainstream schools with their sighted peers.

With the aid of this software, Electronic Braille producers and consumers can access various types of electronic Braille file formats, view the content of the file, and handle various tasks of embossing.

Various types of APAMs are commercially available at a variety of prices and features. The performance of these APAMs is still questionable to the users. Pressure Relief Index (PRI) is a promising indicator that can be used to compare the performance of APAMs. This paper presents a simple procedure to evaluate the performance of APAMs based on the concept of PRI by using FSA pressure mapping system.

In emergency situations as well as ordinary ones deaf people need messages in JSL, because it is their own language. We have various restrictions in using information media such as voice, text, movies and others in emergency situations. In this paper, the indirect messaging method that uses JSL glosses in text form instead of the medium of movie that JSL essentially requires for transmission. From the results of experiments with deaf people and signed language interpreters, we can say JSL-gloss based messaging method is one of candidates for information transmission in certain situations with restrictions in resources.

To this end, the performance of three feature selection techniques are evaluated. The three techniques are Principle Component Analysis, Spatial Filters for Event Related Potentials and Recursive Channel Elimination. They are applied on the data set acquired through 4-class P300 experiments conducted on 5 subjects.
