Our approach is based on a set of common interaction characteristics permeating through several interaction design methodologies, such as User-Centred Design, Participatory Design, Meta-Design and Semiotic Engineering. We identified transparency and meta-communication as two characteristics of user interfaces that can be effective in enhancing Web services usability. We call the new design approach, based on the aforementioned characteristics, Transmeta Design. Finally, we present a case study that demonstrates the application of our approach.","PeriodicalId":262789,"journal":{"name":"Proceedings of the ITI 2013 35th International Conference on Information Technology Interfaces","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129542276","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}

ECG signals are first pre-processed to reduce the baseline drift, noise and other unwanted components that might be present in the signal. The autoregressive modelling of the signals is then applied to extract small set of signal features - coefficients of autoregressive (AR) signal model. Groups of extracted AR parameters for three different ECG types are well separated in feature space which provides for perfect signal classification and heart condition detection for every ECG signal from the test set. In order to assess the accuracy of developed technique for individual patient identification, feature sets are extended with additional parameter - power of AR modelling error. A new ECG based biometric system is proposed and initial patient recognition results presented in the conclusion of the paper.","PeriodicalId":262789,"journal":{"name":"Proceedings of the ITI 2013 35th International Conference on Information Technology Interfaces","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127840884","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 model uses cascading of three taggers with backoff. We use a dictionary of around 32000 words, together their correspondent POS tags and a set of regular expressions rules too. A lemmatize module is implemented in order to convert nouns and verbs to their lemma. The text is tagged initially with a unigram tagger based on the dictionary. This is used as a baseline tagger for a regular expressions tagger. A correction is made for not correct lemmatized words, creating a third lookup tagger. This tagger will be used with the first and second tagger as backoff.","PeriodicalId":262789,"journal":{"name":"Proceedings of the ITI 2013 35th International Conference on Information Technology Interfaces","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121285199","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 Connected Vitality Network puts older adults at the centre of attention to study their needs for designing suitable human computer interaction methods and implement a social (tele)-presence system, which enables closeness and promotes social inclusion.

When comparing relationships among homogeneous regions in one high dimensional domain with regions in another high dimensional domain, the number of possible comparisons may be extremely large and their set complexity unknown. We outline procedures for identifying possible relationships among regions in two different high-dimensional domains. If the data are dense enough, then statistical measures of association can be estimated. These procedures can identify and measure the probability of inter-domain associations of mixed complexity.","PeriodicalId":262789,"journal":{"name":"Proceedings of the ITI 2013 35th International Conference on Information Technology Interfaces","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124987648","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 possibility however is still not fully utilized due to a lack of methods for optimal configuration of software; the allocation of different software components to different computing unit types is crucial for getting the maximal utilization of the platform, but for more complex systems it is difficult to find ad-hoc a good enough or the best configuration.

First, the article reviews the statistical methods for variability assessments of probability distributions. Next, it sums up the entropy concept of uncertainty of systems of events in probability theory. The two concepts are brought closer together on the basis of common experience of predictability. The article also considers the concept of average number of equally probable events based on entropy. Then, it introduces the concept of equivalent number of outcomes based on variability of probability distributions.

The service uses a novel approach to speech synthesis generation, where XML markup is used to control both the speech synthesis and the sound design of a resulting podcast. A two-phase evaluation was carried out: 1) participants listening to the podcasts on desktop computers, 2) participants listening to the podcasts while walking. Our findings show that participants preferred shorter podcasts with sound effects and background music, and were affected by the surrounding environmental noise. However, audio advertising which is part of the service did not have a significant negative effect. Another finding was that the advantage of using multiple voices for content segmentation may have been undermined by difficulties in listener adaptation. The work is part of a new approach to speech synthesis provision, where its style of rendition forms a part of the application design and it is evaluated within an application context.","PeriodicalId":262789,"journal":{"name":"Proceedings of the ITI 2013 35th International Conference on Information Technology Interfaces","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127308283","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}
