{"title":"Controlling user interaction","authors":"D. Kasik","doi":"10.1145/563274.563296","DOIUrl":"https://doi.org/10.1145/563274.563296","url":null,"abstract":"The user of an interactive application is in an anamolous position, especially if he is not one of the elite class known as \"computer bums\". This mythical user is at the end of a process totally controlled by a computer and a program. His communications with the program may suffer greatly because of this total dependence.Control of communication in the batch environment is much more a one-way street. Here the user supplies the program data, and the batch program informs him if something has gone wrong by evicting his run from the machine. The user then consults available documentation (if it exists) or a computer expert (if one exists) for help in solving the problem. The communication between program and user is not critical in this environment; the user is expected to know what to do before he starts the run and can seek assistance outside of the computer.The interactive environment, however, has the user totally at the mercy of the program for diagnostic and prompting information. Even sophisticated graphics-oriented applications, which provide large amounts of useful information through pictures, may not adequately control the user's interaction. The user needs direction imposed on him to successfully solve his problem. At the same time, the system must provide flexibility, i.e., he must not be constrained to a single path of action that may only suit the code's implementor. No user's manual can capture a flow of this nature because of the inherently static nature of words on paper. Furthermore, paging back and forth in a manual to decipher what is to be done next destroys the spontaneity implicit in a successful interactive system.The user must be the main concern of the interactive system for it to be successful. With this goal in mind, Battelle-Columbus has developed a structured approach to controlling user interaction. The approach benefits the implementor as well as the user. It places emphasis on design and checkout of interaction as the first, rather than the last, step in an interactive application.","PeriodicalId":160433,"journal":{"name":"Proceedings of the 3rd annual conference on Computer graphics and interactive techniques","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1976-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117272165","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}

TYPER uses the 20 lines of a CRT terminal screen to implement a window onto the writer's text that can be moved at will. All normal typewriter functions are available plus special functions for the easy insertion, deletion, and modification of text. A non-destructive cursor can be moved about the screen and acts as a pointer to the text. Any printable character typed is immediately placed in the text at the position indicated by the cursor and the change is reflected on the screen. Insertion and deletion of text is accomplished with simple keystrokes. After an insertion or deletion, any extra space between words and space at the end of short lines is filled by \"closing\" the text. Successive words are placed so that they are separated by one space and extra space at the end of a line is filled with words from the succeeding line.Response to TYPER has been excellent. Non-programmers and even those with no computer experience learn its use quickly and are loath to go back to typewriters after using it. In addition, programmers are using it to edit their program code.","PeriodicalId":160433,"journal":{"name":"Proceedings of the 3rd annual conference on Computer graphics and interactive techniques","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1976-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125986367","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}

Clark","doi":"10.1145/563274.563323","DOIUrl":"https://doi.org/10.1145/563274.563323","url":null,"abstract":"The research described in this paper addresses the problems associated with the design of systems for efficiently producing computer-generated pictures and picture sequences of very complex, three-dimensional environments. The thesis of the research is that the geometric structure inherent in the definition of the shapes of three-dimensional objects and environments must be used not just to define their relative motion and placement but also to assist in solving many other problems of systems for producing pictures by computer.The implications are that by using an extension of traditional structure information, or a geometric hierarchy, five significant improvements to current techniques are possible. First, the range of complexity of an environment is greatly increased while the visible complexity of any given scene is kept within a fixed upper limit. Second, a meaningful way is provided to vary the amount of detail presented in a scene both according to the screen area occupied by the objects in the scene and according to camera and object motions. Third, by using the geometric hierarchy, \"clipping\" becomes a very fast logarithmic search for the resolvable parts of the environment within the field-of-view. Fourth, by using this positional hierarchy in conjunction with a storage hierarchy of the sort used in virtual memory computing systems, frame-to-frame coherence and clipping define a graphical \"working set\", or fraction of the total structure that should be present in primary store for immediate access by the visible-surface algorithms. Finally, the proposed structural framework suggests a new recursive descent visible-surface algorithm in which the computation time grows almost linearly with a scene's visible complexity rather than as a worse than linear function of its object-space complexity.","PeriodicalId":160433,"journal":{"name":"Proceedings of the 3rd annual conference on Computer graphics and interactive techniques","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1976-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114228318","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}
