ABSTRACT
BACKGROUND: Recent advancements in machine learning (ML) bring great possibilities for the development of tools to assist with diagnostic tasks within histopathology. However, these approaches typically require a large amount of ground truth training data in the form of image annotations made by human experts. As such annotation work is a very time-consuming task, there is a great need for tools that can assist in this process, saving time while not sacrificing annotation quality. METHODS: In an iterative design process, we developed TissueWand - an interactive tool designed for efficient annotation of gigapixel-sized histopathological images, not being constrained to a predefined annotation task. RESULTS: Several findings regarding appropriate interaction concepts were made, where a key design component was semi-automation based on rapid interaction feedback in a local region. In a user study, the resulting tool was shown to cause substantial speed-up compared to manual work while maintaining quality. CONCLUSIONS: The TissueWand tool shows promise to replace manual methods for early stages of dataset curation where no task-specific ML model yet exists to aid the effort.
ABSTRACT
BACKGROUND: Our aim is to highlight the benefits and limitations of open and non-anonymized peer review. Our argument is based on the literature and on responses to a survey on the reviewing process of alt.chi, a more or less open review track within the so-called Computer Human Interaction (CHI) conference, the predominant conference in the field of human-computer interaction. This track currently is the only implementation of an open peer review process in the field of human-computer interaction while, with the recent increase in interest in open scientific practices, open review is now being considered and used in other fields. METHODS: We ran an online survey with 30 responses from alt.chi authors and reviewers, collecting quantitative data using multiple-choice questions and Likert scales. Qualitative data were collected using open questions. RESULTS: Our main quantitative result is that respondents are more positive to open and non-anonymous reviewing for alt.chi than for other parts of the CHI conference. The qualitative data specifically highlight the benefits of open and transparent academic discussions. The data and scripts are available on https://osf.io/vuw7h/, and the figures and follow-up work on http://tiny.cc/OpenReviews. CONCLUSION: While the benefits are quite clear and the system is generally well-liked by alt.chi participants, they remain reluctant to see it used in other venues. This concurs with a number of recent studies that suggest a divergence between support for a more open review process and its practical implementation.
ABSTRACT
Science communication is facing a paradigm shift, based on the convergence of exploratory and explanatory visualization. In this article, we coin the term exploranation to denote the way in which visualization methods from scientific exploration can be used to communicate results and how methods in explanatory visualization can enrich exploration.
ABSTRACT
BACKGROUND: The Internet's potential as health care tool should be explored. AIM: One objective was to determine the feasibility of constructing a digitally based tool through an iterative design process in cooperation with potential users. The tool's purpose is to alleviate hardships in daily life of relatives of persons with depression. An additional aim was to explore motivation and hindrances to using the tool as a basis for design decisions. METHOD: An iterative design approach, including data collection through focus groups and with paper and web-based prototypes, was used. RESULTS: Cooperation with potential users, using an iterative design process, was valuable in developing the digitally based tool. Motivations (i.e. to create understanding and rehabilitate oneself) and hindrances (i.e. lack of time or energy) to using the tool were illuminated. Design decisions were based on consideration towards participants' privacy concerns, needs of support and the depression's influence on the relatives' daily life. CONCLUSION: Prototypes and cooperation with potential users were essential and valuable for the iterative development of the website.
