The special attention is paid to systems with motivation that can be treated as a characteristic representative of statistical social systems. The dynamics of such objects is governed by cooperative phenomena, which enables us to introduce the notion of characteristic element. Some examples of possible virtual experiments enabling us to investigate the basic properties of human perception, memory effects, learning and adaptation to environment changing in time are also discussed.","PeriodicalId":407345,"journal":{"name":"Joint International Conference on Human-Centered Computer Environments","volume":"4 37","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132747535","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}

Many virtual environment (ve) models are available in the Alice 3d environment. We created ve scenes using the Alice 3d ide (integrated development environment). We deploy a beat detector to detect the rhythm of a song, based on pd (Pure Data, a free dataflow programming environment similar to max/msp). It can extract the beat of a song in realtime. Using our Alice--Cve (Collaborative Virtual Environment) Bridge and Pd--Cve Bridge, we can create a communication link between the beat detector and Alice 3d environment. The cve is a Java client--server protocol in which clients connect to session server host via channels, and when clients need to communicate with each other they subscribe to the same channel. The Alice--Cve Bridge allows any device that can connect to the cve server to communicate with Alice without regard for architectural differences. When a song is played, its beat can be detected and data sent to animate objects and avatars. An avatar can dance (admittedly poorly) in the Alice 3d environment while receiving a realtime rhythm data stream from a cve session server. Stage color and other attributes a can also be rhythmically changed according to the beat using the same communication link.","PeriodicalId":407345,"journal":{"name":"Joint International Conference on Human-Centered Computer Environments","volume":"199 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":"132303559","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 have created a virtual concert application using Alice, a 3d rapid prototyping programming environment, in which instruments are arranged around a virtual conductor (in this case the user) located at their center. A user-conductor with a smartphone can use it as a simplified baton, pointing at a preferred instrument and tapping to select or start playing. When selected, an instrument is jiggled or its components dilated and contracted, and a spotlight appears until the instrument is muted, providing the conductor and audience with visual cues about the ensemble. One can also adjust volume/panning of a selected instrument by sliding corresponding controls on the smart-phone screen. Alice 3 (Beta) provides a rich api to control and display objects, but native audio capabilities are limited to playing an audio file and adjusting individual volume before playing. Using a plugin for NetBeans, Alice programs (scenarios) can be edited as Java code outside Alice. With the Java Sound api, which provides more complete control for controlling sampled audio and midi, we implement audio-related functions to the virtual concert. Smartphones have magnetometers that can be used to detect yaw, which data is acquired through a compatible programming language and library. Spatial information of smartphones can be accessed using the platform's api and transmitted to a collaborative virtual environment (cve) session server via Wi--Fi. A middleware program, the \"Alice--Cve Bridge,\" retrieves these events through the server and selects/plays/adjusts instruments in the Alice-rendered virtual environment. Such explorations suggest the power of emerging mobile devices as generalized remote controls for interactive multimedia and ubiquitous computing.","PeriodicalId":407345,"journal":{"name":"Joint International Conference on Human-Centered Computer Environments","volume":"215 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":"134304454","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}

What appears to be lacking is an empirical study of the connection between entropy and musical perception. This paper describes results of an experiment designed to determine the relevance of entropy to subjects' dissimilarity judgments on pairs of melodic sequences. The hypothesis was that dissimilarity judgments by subjects on pairs of unfamiliar tonal sequences drawn from a common pitch set are largely a function of average sequence entropy and average sequential interval size, when the sequences are uniform in all respects except for the ordering of pitches. Five stationary ergodic Markov-1 chains of increasing entropy were defined on a common pitch set. From each chain, two sequences of identical entropy were generated: the first sampled directly from the chain, and the second by applying to each sequence element of the first a random permutation of the pitch set. In this fashion, entropy and average interval size variables could be varied quasi-independently. Timbre, duration, and loudness were held constant. Subjects heard all possible unordered pairs of synthesizer-generated sequences through headphones, and indicated a subjective dissimilarity rating for each pair. Two forms of analysis yielded different results. Subject dissimilarity judgments between sequences were shown to be well correlated with a Euclidean distance function on average interval size and entropy. However, multidimensional scaling analysis revealed only average interval size to be a salient judgment factor, not entropy.","PeriodicalId":407345,"journal":{"name":"Joint International Conference on Human-Centered Computer Environments","volume":"51 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":"126315086","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}
