The VPF supports the development of programs written in a programming language called a form manipulation language. The language is a so-called iconic language and provides not only programming facilities but also form-oriented operations. VPF provides the following features: (1) hierarchical views that support views for various abstract levels of program specification and execution; (2) visualization of the program itself and its run-time behavior with graphical representation; and (3) modeless operations that enable a program to be developed under only one execution mode. These features give the programmers good comprehension of program development and enhance productivity and reliability of the application programs.<<ETX>>","PeriodicalId":326582,"journal":{"name":"[Proceedings] 1989 IEEE Workshop on Visual Languages","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116237003","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}

Nor does the user know clearly what should be retrieved. How to get at the data becomes a central problem for very large databases. The author suggests an approach based upon data visualization and visual reasoning. The idea is to transform the data objects and present sample data objects in a visual space. The user can then incrementally formulate the information retrieval request in the visual space. By combining data visualization, visual query, visual examples and visual clues, he hopes to come up with better ways for formulating and modifying a user's query. A prototype system using the Visual Language Compiler and the VisualNet is then described.<<ETX>>","PeriodicalId":326582,"journal":{"name":"[Proceedings] 1989 IEEE Workshop on Visual Languages","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122062228","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}

Thus considerable interest has arisen in algorithms for drawing directed graphs so that they are easy to understand and remember. The paper defines three aesthetic criteria for drawings of directed graphs, and discusses a general method for obtaining drawings according to these criteria. Several recent algorithms to draw directed graphs are instances of this general method. The aesthetic criteria can be viewed as goals of optimization problems. Each step of the general method aims to achieve one of the criteria by solving these optimization problems. The authors discuss the current state of knowledge of each of these problems.<<ETX>>","PeriodicalId":326582,"journal":{"name":"[Proceedings] 1989 IEEE Workshop on Visual Languages","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134415493","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}

Various methods of handling video data on the MediaBENCH are introduced and discussed to show how video data can be manipulated on visual database systems which deal with spatial and temporal factors. A visual interface using video icons is quite suitable to video editing, presentation support or other electronic video document systems.<<ETX>>","PeriodicalId":326582,"journal":{"name":"[Proceedings] 1989 IEEE Workshop on Visual Languages","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131813987","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}

A three-dimensional animation-oriented programming language called LIVE is presented. LIVE is an attempt to integrate the visual and textual programming paradigms. Visual objects are interactively manipulated by both a visual representation (pick-by-name interface) and a textual representation (pick-by-position interface). The system informs a user in a text form how his or her visual operation is interpreted. A selected interpretation unsuitable to the users can be interactively resolved using a pick-by-name interface. LIVE introduces a programming-by-multiple-examples paradigm based on a visual guard concept, which is analogous to the concept of logic programming languages. This paradigm enables one to make a visual program in a way which is simple and easy to understand.<<ETX>>","PeriodicalId":326582,"journal":{"name":"[Proceedings] 1989 IEEE Workshop on Visual Languages","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126735831","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}
