Moreover, those hierarchy elements can carry additional information worth investigating for a software developer. Getting an overview of both the hierarchy and the attached static or dynamic data can become a tedious task if it is not supported by a visually scalable visualization technique. In this paper, we use a hierarchy visualization based on the visual metaphor of indentation to generate an overview of the software system hierarchy and easily attach additional attributes. The extra information is aligned with the hierarchy elements and, hence, supports visual comparisons of the attachments on different levels of hierarchical granularity. Through interaction, we provide additional views on the data, e.g., by filtering, hierarchy transformations, or details-on-demand. We illustrate the usefulness of our hierarchy visualization technique by means of an application example exploring data from the open-source software project jEdit. We investigated the readability of the hierarchy visualization with a user experiment, comparing indentation to node-link diagrams for varying sizes of a hierarchy.","PeriodicalId":253313,"journal":{"name":"2017 IEEE Working Conference on Software Visualization (VISSOFT)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116324482","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}

Paech","doi":"10.1109/VISSOFT.2017.18","DOIUrl":"https://doi.org/10.1109/VISSOFT.2017.18","url":null,"abstract":"Continuous software engineering (CSE) includes activities to continuously evolve software artifacts. Along with these activities, developers employ knowledge such as usage and decision knowledge. Usage knowledge helps developers to understand how users apply software, while decision knowledge comprises all decisions taken during CSE and their rationale. However, due to the frequency, extent, and complexity of knowledge in CSE environments, accessing and processing knowledge is challenging for developers. We propose a dashboard for developers that visualizes knowledge from various sources. This enables developers to follow, reflect, interact, and react on knowledge in CSE environments. We introduce springboards that serve as knowledge selectors while the selected extract of knowledge is visualized in widgets. Widgets allow developers to gain insight into knowledge. We suggest three widget classes: spot, compare, and range. We discuss dashboard extensions such as interaction triggers to add, modify, or combine knowledge. We plan to implement the dashboard and evaluate it with teams during software development projects in an industrial setting.","PeriodicalId":253313,"journal":{"name":"2017 IEEE Working Conference on Software Visualization (VISSOFT)","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133086360","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}

Diehl","doi":"10.1109/VISSOFT.2017.24","DOIUrl":"https://doi.org/10.1109/VISSOFT.2017.24","url":null,"abstract":"Sketching is an important activity for understanding, designing, and communicating different aspects of software systems such as their requirements or architecture. Often, sketches start on paper or whiteboards, are revised, and may evolve into a digital version. Users may then print a revised sketch, change it on paper, and digitize it again. Existing tools focus on a paperless workflow, i.e., archiving analog documents, or rely on special hardware–they do not focus on integrating digital versions into the analog-focused workflow that many users follow. In this paper, we present the conceptual design and a prototype of LivelySketches, a tool that supports the \"round-trip\" lifecycle of sketches from analog to digital and back. The proposed workflow includes capturing both analog and digital sketches as well as relevant context information. In addition, users can link sketches to other related sketches or documents. They may access the linked artifacts and captured information using digital as well as augmented analog versions of the sketches. We further present results from a formative user study with four students and outline possible directions for future work.","PeriodicalId":253313,"journal":{"name":"2017 IEEE Working Conference on Software Visualization (VISSOFT)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121995993","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}
