Opportunities of Touch-Enabled Spherical Displays to support Climate Conversations

We explore how touch-sensitive spherical displays can support climate conversations in museums and science centers. These displays enable intuitive and embodied interaction with complex climate data, and support collective exploration. However, current interaction capabilities of spherical displays are limited. Therefore, this exploratory study aims to identify potential opportunities to develop meaningful interactions and technical solutions. Through two workshops, key opportunities were identified to improve visitors’ understanding and navigation of climate data, along with recommendations for technical implementation. Our results provide guidelines and aspects to consider for future research and development in this area.

💡 Research Summary

The paper investigates how touch‑enabled spherical displays can be leveraged to foster climate‑related conversations in museums and science centers. Recognizing that climate data are massive, multidimensional, and often difficult for lay audiences to interpret, the authors argue that the immersive, globe‑shaped visualizations offered by spherical displays can improve spatial understanding and support collaborative learning. However, current commercial implementations rely mostly on pre‑programmed visualizations or indirect controls (e.g., external touch screens), providing little direct, multi‑user touch interaction. To address this gap, the authors conducted two exploratory workshops at the Visualization Center C in Norrköping, Sweden. Workshop 1 involved three computer‑science participants and focused on brainstorming interaction ideas using climate‑conversation cards and visualization cards. Workshop 2 involved four participants from communication, sustainability, education, and media‑technology backgrounds and refined the ideas generated in the first session. Two spherical displays were used: a 60 cm touch‑sensitive globe supporting slide‑to‑rotate and tap‑to‑select gestures, and a larger 120 cm globe controlled via an external fixed touch screen that offered layer selection, swipe‑based rotation, and animation playback controls. Data were collected through video recordings, photographs, and sticky‑note artifacts; the researchers performed iterative thematic coding to extract interaction opportunities, challenges, and design recommendations.

The analysis yielded two major clusters of opportunities: (1) Understanding the data and (2) Navigating the data. Under “Understanding,” participants repeatedly requested easy access to legends and textual descriptions, the ability to toggle information layers (e.g., country borders, socioeconomic data), mechanisms to relate visualizations to personal experiences, and links to external sources such as climate‑model reports. They also highlighted visual‑mapping issues, such as color perception varying with underlying terrain, suggesting the need for consistent color palettes and foreground‑background design rules. Under “Navigating,” participants emphasized the need for granular point‑level data (e.g., local CO₂ concentrations), precise timeline controls (play/pause, scrubbing bar, speed adjustment), and intuitive globe rotation that accommodates multiple users without causing visual conflicts. They noted that a single rotation affects all viewers, potentially disrupting collaboration, and proposed fixed‑view or token‑based rotation permissions. Comparative analysis across space, time, and data layers was identified as a critical yet under‑supported task; participants suggested split‑view or opacity‑adjustable layering to compare, for example, sea‑ice temperature with precipitation patterns.

Based on these findings, the authors propose concrete technical implementations: (a) a multi‑layer management UI driven by two‑finger pinch‑zoom, swipe gestures, and on‑screen toggles; (b) context‑sensitive pop‑up or audio legends that appear on touch; (c) “smart tooltip” overlays that display metadata (raw values, uncertainty ranges) when a user taps a specific region; (d) a dedicated timeline bar with scrubbing and speed controls; (e) a user‑token rotation protocol that grants rotation rights to one participant at a time while allowing others to view from a fixed perspective; and (f) split‑view or adjustable‑opacity layering to support side‑by‑side or overlaid comparisons. The paper argues that these interaction designs can transform spherical displays from passive visual media into active, collaborative conversation platforms, helping to break the “climate spiral of silence” by providing inclusive, value‑centered discussion spaces.

The authors conclude by emphasizing the need for longitudinal field studies to assess long‑term usability, cognitive load, and affective outcomes (e.g., reduced climate anxiety). Future work should explore integration with AR/VR overlays, richer multimodal feedback (haptic, auditory), and mechanisms for conveying data provenance and uncertainty to maintain trust. Overall, the study offers a roadmap for HCI researchers, museum curators, and climate communicators to design touch‑enabled spherical interfaces that meaningfully support public engagement with climate science.
