The visualization uses 3D glyphs such as wireframe and hole shapes, as well as convex and concave shapes. A semantic constraint, such as a type constraint in an assignment, is represented by an inclusive match between 3D glyphs. The use of wireframe and hole shapes enables representation of polymorphic constraints. An experimental evaluation showed that the 3D glyphs are easier to learn and are faster to answer than 2D glyphs and 1D symbol sequences.","PeriodicalId":241986,"journal":{"name":"2005 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC'05)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114161960","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}

Among those the meta-modeling approach used to define the Unified Modeling Language (UML), and the graph transformation approach are very popular. Especially the combination of both, using meta-modeling to define the syntax of a VL and graph transformation for specifying model transformations has been considered conceptually and explored in a number of applications. A formal integration of both approaches has just been started by integrating classical algebraic graph grammars with a node type inheritance concept. In this paper, the integration of inheritance is extending to attributed graph transformation. More precisely, we define attributed type graphs with inheritance leading to a formal integration of inheritance with typed attributed graph transformation.","PeriodicalId":241986,"journal":{"name":"2005 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC'05)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131034626","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}

Speech interfaces can help developers reduce their dependence on typing. However, existing programming by voice techniques make it awkward for programmers to enter and edit program text. To design a better alternative, we conducted a study to learn how software developers naturally verbalize programs. We found that spoken programs are different from written programs in ways similar to the differences between spoken and written English; spoken programs contain lexical, syntactic and semantic ambiguities that do not appear in written programs. Using the results from this study, we designed Spoken Java, a semantically identical variant of Java that is easier to say out loud. Using Spoken Java, software developers can speak more naturally by verbalizing their program code as if they were reading it out loud. Spoken Java is analyzed by extending a conventional Java programming language analysis engine written in our Harmonia program analysis framework to support the kinds of ambiguities that arise from speech.","PeriodicalId":241986,"journal":{"name":"2005 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC'05)","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129425912","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 domain is strongly devoted to the modeling of reactive behavior using StateChart variants. In this context, the direct execution of UML state machines is an interesting alternative to native code generation approaches since it significantly increases portability. However, fully featured UML 2.0 State Machines may contain a broad set of features with complex execution semantics that differ significantly from other StateChart variants. This makes their direct execution complex and inefficient. In this paper, we demonstrate how such state machines can be represented using a small subset of the UML state machine features that enables efficient execution. We describe the necessary model transformations in terms of graph transformations and discuss the underlying semantics and implications for execution.","PeriodicalId":241986,"journal":{"name":"2005 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC'05)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129002456","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 paper describes a set of tools, called Team Tracks, designed to ease program comprehension by showing the source code navigation patterns of fellow development team members. One technique shows a list of related items, given that the user is viewing a given method or class. Another technique shows the favorite classes, by showing a class hierarchy view that hides less frequently visited classes, methods, and members. Two user studies, a laboratory study and a field study, were run to evaluate the effectiveness of these techniques. The results of the two studies demonstrate that sharing navigation data can improve program comprehension and is subjectively preferred by users.","PeriodicalId":241986,"journal":{"name":"2005 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC'05)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130013904","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}
