Overview-detail interfaces (ODIs), which present an overview of multiple items alongside a detailed view of a selected item, are ubiquitously implemented in software interfaces. However, the current design and development pipeline lacks the infrastructure to easily support end-user customization, limiting its ability to support diverse information needs. This research envisions a development cycle for building malleable interfaces—one where designers, developers, and end-users alike can create, modify, and use the interfaceequally. To establish a foundation for this infrastructure, we in-troduce Meridian, a design framework for guiding and facilitatingthe creation of malleable ODIs. The framework consists of a high-level declarative specification language for ODIs as well as its tools, including a UI development package and a no-code web builder to facilitate the development and design of malleable ODIs. We demonstrate how Meridian supports designers, developers, and end-users alike in designing, implementing, and interacting with ODIs in novel ways using their respective familiar tools and platforms. Finally, we discuss technical tradeoffs, potential solutions, and opportunities for enabling interface malleability by default.

Abstract On 04 December 2021, a total solar eclipse occurred over west Antarctica. Nearly an hour beforehand, a geomagnetic substorm onset was observed in the northern hemisphere. Eclipses are suggested to influence magnetosphere‐ionosphere (MI) coupling dynamics by altering the conductivity structure of the ionosphere by reducing photoionization. This sudden and dramatic change in conductivity is not only likely to alter global MI coupling, but it may also introduce a variety of localized instabilities that appear in both hemispheres. Global navigation satellite system (GNSS) based observations of the total electron content (TEC) in the southern high latitude ionosphere during the December 2021 eclipse show signs of wave activity coincident with the eclipse peak totality. Ground magnetic observations in the same region show similar activity, and our analysis suggest that these observations are due to an “eclipse effect” rather than the prior substorm. We present the first multi‐point interhemispheric study of a total south polar eclipse with local TEC observational context in support of this conclusion.more » « less
