However, programming is difficult to learn, even for adults. Children often lose interest in further exploration of programming through adult learning mechanisms. Environments that support a gradual transition from manual control of the physical artifact to complete programming substantially simplify the process of programming. The combination of LEGOsheets and the Programmable Brick is an educational environment that provides a gentle, enticing introduction to programming and the design of mechanical artifacts. This paper introduces LEGOsheets, a rule-based programming environment that allows children to simulate and manipulate the LEGO Programmable Brick.","PeriodicalId":438013,"journal":{"name":"Proceedings of Symposium on Visual Languages","volume":"170 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114465657","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 user interface allows the user to construct diagrams in the visual language from primitive tokens such as text, lines, rectangles or circles. These tokens are incrementally parsed into sub-diagrams. During parsing, automatic error correction removes geometric errors, providing feedback about what has been recognized. The user may add or delete tokens and may manipulate components of the diagram. During manipulation, the user interface takes account of the semantics of the diagram, preserving the geometric relationships dictated by the visual language. Our research has particular application to user interfaces for pen-based computers.","PeriodicalId":438013,"journal":{"name":"Proceedings of Symposium on Visual Languages","volume":"133 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116719344","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}

Like programming language systems, digital design systems must have expressive power sufficient for representing any circuit. Since specifying complex circuits requires repetitive and conditional structures analogous to iteration, recursion and conditionals in programs, languages for designing complex devices are usually based on textual programming languages, as with the hardware description language VHDL. The advent of full-featured visual programming languages, however, raises the possibility we consider here: that mechanisms used to visually express compact and powerful program structures could be generalised to digital circuit design.","PeriodicalId":438013,"journal":{"name":"Proceedings of Symposium on Visual Languages","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129172351","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}

Furthermore, their success will largely depend on the programming environment which is provided for them. Programming environment generators, generate programming environments for formally specified languages. We discuss specification of visual languages and the generation of visual environments. We focus on a picture definition language, VODL, which serves as the basis for defining the syntax of visual languages. We present the language definition and an example showing how VODL is used in defining language syntax and thereafter generating visual editors. Finally, we discuss how to extend this approach in creating a visual specification formalism and a supporting environment for specifying the syntax and semantics of visual languages.","PeriodicalId":438013,"journal":{"name":"Proceedings of Symposium on Visual Languages","volume":"308 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115550790","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 permits programmers to specify the behaviors of agents in the class of program objects in the Agentsheets system of Repenning. The resulting agents can be used in designing simulations for two-dimensional cellular worlds such as in automobile traffic flow situations, video games, and cellular automata studies. The programming facility, called \"Agent Builder\", is integrated into the Agentsheets system (providing a substitute for the non-visual AgenTalk editor) in such a way that agent programming becomes a process of arranging icons in a worksheet, using a special gallery of icons. Several applications of Agent Builder are presented, and its limitations and possible extensions are discussed.","PeriodicalId":438013,"journal":{"name":"Proceedings of Symposium on Visual Languages","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126340071","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 use of semantic constraints on diagram editors 在图编辑器上使用语义约束

Editors for diagramming notations such as state transition networks, Petri nets or the entity-relationship data model, are always confronted with a problem: how much guidance should be given to the user throughout the editing task? Not enough guidance allows the diagram to evolve to nonplausible configurations and may provoke the user to feel lost in the editing process. At the other extreme, if too much guidance is provided the user feels like being shepherded through the diagram drawing; this results in an obtrusive and unfriendly system. Current tools normally offer a trade-off solution based on the introduction of some semantic constraints in the diagram editor to forbid a number of operations. To assert the correctness of the diagram, the reset must explicitly request it to be checked. I believe this solution is not satisfactory. All the semantic constraints should be embedded in the editor in order to allow automatic diagram validation. The challenge is: how to do it without limiting the user's freedom during the editing task? I propose an approach that provides a solution to this problem.","PeriodicalId":438013,"journal":{"name":"Proceedings of Symposium on Visual Languages","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133665428","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}
