Conventionally, the internal state is estimated based on linguistic information of the previous utterance, but this approach cannot applied to the user who did not make an input utterance in the first place. Thus, we are developing a method to estimate an internal state of a spoken dialogue system's user before his/her input utterance. In a previous report, we used three acoustic features and a visual feature based on manual labels. In this paper, we introduced new features for the estimation: length of filled pause and face orientation angles. Then, we examined effectiveness of the proposed features by experiments. As a result, we obtained a three-class discrimination accuracy of 85.6% in an open test, which was 1.5 point higher than the result obtained using the previous feature set.","PeriodicalId":222377,"journal":{"name":"2012 5th International Conference on Human System Interactions","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125942705","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 proposed scheme is a key-dependent, content based and non-deterministic neighborhood-dependent method so that it can resist the well-known attacks including the transplantation attack and vector quantization attack. The most remarkable feature of the proposed scheme is that only a small number of wavelet coefficients are watermarked but all are implicitly protected. So the embedding distortion is dramatically reduced without compromising the authentication resolution. In addition, analyses on both algorithm and security of the scheme are provided, and the simulation results are also presented to visually validate the proposed scheme.","PeriodicalId":222377,"journal":{"name":"2012 5th International Conference on Human System Interactions","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126979422","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}

Traditionally, research has focused on optimization towards a final solution but this paper focuses on minimizing disturbance impact due to changing conditions. A Multi-Agent System (MAS) is proposed in which users are represented as autonomous agents negotiating with one another to repair a timetable. From repeated negotiations, agents learn to develop a model of other agent's preferences. The MAS is simulated on a factorial experiment set up and varying the cooperation level, learning model and selection strategy. A provenance-centred approach is adopted to improve the human aspect of timetabling to allow users to derive the steps towards a solution and make changes to influence the solution.","PeriodicalId":222377,"journal":{"name":"2012 5th International Conference on Human System Interactions","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131043731","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}

For example in Indonesia, there are around 2, 785 senior high school students failed in the National Examination in 2010 because most of them choose unappropriate field of study which is not related to interest and talent. It is important to assist students to choose a potential area of study commensurate with their talents and interests and which covers all possible fields of study. To achieve that aim, standard to represents knowledge as a set of concepts is needed. This paper proposes an ontological framework to assist students to recognize the prospective fields of study related to their talent and interest. The framework is including two ontologies with different perspectives which will be linked using matching engine to get the possible field of study. Then, selection engine is to be used to get the final result of the appropriate field of study for student. This framework can be applied in educational field to improve student's capacity and to help them in maintain their future life.","PeriodicalId":222377,"journal":{"name":"2012 5th International Conference on Human System Interactions","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123764957","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}

Our developing system consists of a seating cushion which the patient sits on and four air cells which can lift or incline the seating cushion. Each air cell is actuated by small air compressor, which can drive using batteries on the wheelchair respectively, and each compressor has a pressure sensor on its body. In this paper, we develop the depressurization assistance control scheme based on the pressure distribution estimation. For realizing the pressure distribution estimation during the depressurization motion, we analyze the hip depressurization operation by the nursing specialists and from analytical results, our system uses the center of pressure as an index value. Using the estimated results, our system controls the inclination of its seating cushion for increasing the depressurization performance. With our proposed system, the patient can depressurize on his sacral part without special operation. The performance of our system is verified by experiments using our prototype.","PeriodicalId":222377,"journal":{"name":"2012 5th International Conference on Human System Interactions","volume":"199 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116163102","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}

It uses a computer generated video avatar, which articulates a sender's message that has been tagged using an XML markup language. With the advent of smart phones, a new less complex screen by screen interface was required due to their reduced screen size and power. A new Smiliemail client could also cater for the mobile paradigm of \"media-rich communication everywhere\". Interaction between users on Social Network Sites (SNS), such as Facebook often use emotional or affective communication. However, plain text messages, even if tempered with appropriate smilie icons, often cause misunderstanding, leading to flame wars or similar. Hence the Smiliemail affective avatars may provide an effective inter-user communication on SNSs. This case-study discusses the user interface evolution from the existing web-based Smiliemail interface, through to a smart phone interface, and finally to the SmilieFace Facebook application \"canvas\" interface.
