In this paper, I present an example Idea Garden feature hosted in the CoScripter environment, and the results from a qualitative evaluation of how the feature helped users overcome a barrier and learn the related programming knowledge as well as a problem-solving strategy. Then I outline the plan for a quantitative evaluation. Finally, I discuss the generalizability of the Idea Garden approach.","PeriodicalId":156972,"journal":{"name":"2012 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130293333","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}

Indeed, in a computing world that is growingly distributed, the process of elaborating spreadsheets is often performed in a collaborative way, by many actors. In a model-driven environment, this means that one model must have many instances, one for each of the actors involved. Later, instances may be evolved independently and synchronization techniques are needed to evolve the original model so that conformity is restored.","PeriodicalId":156972,"journal":{"name":"2012 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC)","volume":"123 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134520871","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 introduces a new software development approach where stories written in commonly understood structured natural language gain runtime semantics. Stories are precisely linked to domain concepts and actions, thus forming the application logic of the system. These constructs are written at a high level of abstraction, very close to detailed software requirements specifications. In fact, they are structured into familiar use case models that include special “invocation” relationships between use cases. At the same time, the paper proposes precise translational semantics for such defined stories. For each story element, equivalent Java code is derived. This semantics has been implemented within a tool containing a story editor and a code generator producing fully dynamic application logic code with Swing-based user interface. Ease of use of the new story language and usefulness of the generated Java code has been evaluated through student assignment projects.","PeriodicalId":156972,"journal":{"name":"2012 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133518846","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}

In a three condition controlled experiment, we examined how changing the presentation of the data elements referred to in a game's goals would influence the purposefulness of the goals and thereby affect players' motivation to achieve them. A total of 121 self-described programming novices were recruited online to play the game. We found that 1) those using vertebrate elements completed twice the number of levels compared to those using inanimate elements, 2) those using vertebrate and invertebrate elements spent significantly more time playing the game overall compared to those using inanimate elements, and 3) those using inanimate elements were more likely to quit the game, especially on difficult levels. These findings suggest that the presentation of game elements that influence the purposefulness of goals can play a significant role in keeping self-guided learners engaged in learning tasks.","PeriodicalId":156972,"journal":{"name":"2012 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126519485","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}

Yet, very little attention has been devoted to the choice of symbols used. This article contributes to the visual languages literature by providing an enriched understanding about how symbol choice affects the ease of memorizing and recalling visual diagrams. Specifically, the experiment reported here was designed to compare the effect of three different symbol sets of visual languages from the business process modeling domain on diagram recall. Quantitative analysis based on data collected from 37 business school students, revealed that symbol choice significantly influences memory of visual aspects of the diagrams as layout. However, the study did not find a significant effect of symbol choice on recognition accuracy of the semantic content of the diagrams. Overall, the findings underscore the relevance of symbol choice for visual language design.","PeriodicalId":156972,"journal":{"name":"2012 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131180716","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}

However, information flow in hospitals is still tied to traditional manual or digitised lengthy patient record files that are often not accessible while caregivers are attending to patients. Leveraging the proliferation of pervasive awareness technologies (sensors, actuators and mobile displays), recent studies have explored this information presentation aspect borrowing theories from context-aware computing, i.e., presenting subtle information contextually to support the activity at hand. However, the understanding of the information space (i.e., what information should be presented) is still fairly abstruse, which inhibits the deployment of such real-time activity support systems. To this end, this paper first presents situated glyphs, a graphical entity to encode situation specific information, and then presents our findings from an in-situ qualitative study addressing the information space tailored to such glyphs. Applying technology probes using situated glyphs and different glyph display form factors, the study aimed at uncovering the information space pertained to both primary and secondary medical care. Our analysis has resulted in a large set of information types as well as given us deeper insight on the principles for designing future situated glyphs. We report our findings in this paper that we expect would provide a solid foundation for designing future assistive systems to support patient care activities.","PeriodicalId":156972,"journal":{"name":"2012 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128616303","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 principles behind literate programming have been proposed as an approach to addressing this. To study the potential efficacy of these principles in the general end-user programming case, they were applied to spreadsheets, the most common end-user programming environment, to produce a literate spreadsheet design. The resulting artifact was then evaluated through a user study with a focus on the literate design's effect on user comprehension and modification performance in each of the data, formula and dependency layers of the spreadsheet model. Significant performance improvements were observed in the formula and dependency layers over the traditional spreadsheet design, suggesting that the literate form can help improve end-user problem-solving knowledge reuse.","PeriodicalId":156972,"journal":{"name":"2012 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC)","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124137485","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}
