In particular, the task of computing disparity estimates is normally performed independently of ongoing egomotion and environmental recovery processes. Can information from these processes be exploited in the notoriously hard problem of disparity field estimation? Here we explore the use of feedback from the environmental model being constructed to the static stereopsis task. A prior estimate of the disparity field is used to seed the stereomatching process within a probabilistic framework. Experimental results on simulated and real data demonstrate the potential of the approach.","PeriodicalId":407345,"journal":{"name":"Joint International Conference on Human-Centered Computer Environments","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133986521","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}

Nowadays, many children use the game-based learning materials for leaning. However, the difficulty and frustration of the materials usually decrease learners' pleasure and interests. Learners' facial emotions intuitionally respond to their learning condition. Accordingly, the aim of the study is developing the affective interface of the game-based adaptive learning to enhance children's learning motivation. The various difficulty levels of a puzzle game and learning contents are designed to adapt in accordance to the learner's facial emotion which is recognized and classified by Ekam's FACS. Three groups of the elementary school students are recruited to separately participate in the evaluation experiments. One group is for the adaptive game, another for the adaptive learning content, and the other one is the control group for no adaptive learning. Afterword the subjects use the affective usability scale to evaluate the system. The results reveal the game-based learning system could enhance learners' learning motivation and satisfaction. Conclude that the affective interface developed by facial affective computing is proposed to apply on the adaptive learning.","PeriodicalId":407345,"journal":{"name":"Joint International Conference on Human-Centered Computer Environments","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132766705","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}

Although the underlying speech technology is mostly language-independent, differences between languages with respect to their structure and grammar have substantial effect on the recognition systems performance. The Russian language has a complicated word formation system, which is characterized by a high degree of inflection and unrigidness of the word order. This greatly reduces the predictive power of the conventional language models and consequently increases the error rate. Current statistical approach to speech recognition requires large amount of both speech and text data. There exist several Russian speech databases and their descriptions are given in this paper. In addition, we describe and compare several speech recognition systems developed in Russia as well as in some other countries. Finally we suggest some promising directions for further research in Russian speech technology.","PeriodicalId":407345,"journal":{"name":"Joint International Conference on Human-Centered Computer Environments","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115963317","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}

However, before surface computers become widely accepted, there are many questions with respect to sound production and reception for these devices that need to be explored. Here, we describe two experiments that examine sound localization on a horizontal (table-top computer) surface. In the first experiment we collect \"ground truth\" data regarding physical sound source localization by employing a computer controlled grid of 25 equally spaced loudspeakers. In the second experiment we investigate virtual sound source localization using bilinear interpolation amplitude panning method and a modified quadraphonic loudspeaker configuration whereby four loudspeakers are positioned at each corner of the surface in a manner such that they emanate sound in an \"upwards\" direction. Obtained results indicate that sound localization of virtual sound sources on a horizontal surface is prone to errors and this is confirmed with our physical sound source \"ground truth\" data.","PeriodicalId":407345,"journal":{"name":"Joint International Conference on Human-Centered Computer Environments","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128466529","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}

We describe a tangible multitouch planning system, enabling a single user to prepare and customize scene flow and settings. Users can view and interact with virtual objects by using a tangible user interface on a capacitive multitouch surface. In a 2D setting created TV scenes are simultaneously rendered as separate view using a production/target renderer in 3D. Thereby the user experiences a closer reproduction of a final production and set assets can be reused. Subsequently, a user can arrange scenes on a timeline while maintaining different versions/sequences. The system consists of a tablet and a workstation, which does all application processing and rendering. The tablet is just an interface connected via wireless LAN.","PeriodicalId":407345,"journal":{"name":"Joint International Conference on Human-Centered Computer Environments","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130409725","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}

Written kanji are essentially flat and thus resemble alphabet characters and numerals but in contrast to them many kanji and kanji components are derived from and thus directly associated with existing physical artifacts and notions. For novice kanji learners, however, it is usually very hard to analyze and map kanji and kanji components to existing artifacts. We attempt to facilitate this process by introducing various tangible kanji representations and bringing flat, written kanji back to the tangible 3D world where learners can get proper touch and feel of them. We report on the design and development of different spatial kanji models and construction sets for kanji learning experiments and research.","PeriodicalId":407345,"journal":{"name":"Joint International Conference on Human-Centered Computer Environments","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127986466","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}
