Chartjunk is a popular yet contentious topic. Previous studies have shown that extreme minimalism is not always best, and that visual embellishments can be useful depending on the context. While more knowledge is being developed regarding the effects of embellishments on users, less attention has been given to the perspectives of practitioners regarding how they design with embellishments. We conducted semi-structured interviews with 20 data visualization practitioners, investigating how they understand chartjunk and the factors that influence how and when they make use of embellishments. Our investigation uncovers a broad and pluralistic understanding of chartjunk among practitioners, and foregrounds a variety of personal and situated factors that influence the use of chartjunk beyond context. We highlight the personal nature of design practice, and discuss the need for more practice-led research to better understand the ways in which concepts like chartjunk are interpreted and used by practitioners.
Self-Photography better known as 'selfies' have become a trend due to incoming of Social Networking sites like Facebook, twitter, Instagram etc. Selfies are a cumbersome task to handle because of difficulty in setting the correct frame and triggering the capture. In our research work, we explored different actions and the tangible interactions to trigger the actions for capturing the photograph. We also explored different scenarios for taking selfies. We argue that the tangible interactions which we identified not only provided a better way for taking selfies but also provided playful actions for taking photographs.
Guidelines are commonly viewed as an important form of design knowledge that can support the principled application of research findings to visualization design. Researchers regularly propose design guidelines as outputs from studies with the aim of prescribing design activity. However, inquiry into the actual use of design guidelines by practitioners is often unaddressed or left for future work. We propose there is a need for visualization researchers to better understand the realities of design practice, especially its epistemological foundations, and how different forms of design knowledge are actually employed rather than how researchers imagine them to be employed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
