The work, published open access in the Journal of Ambient Intelligence and Humanized Computing, responds to a long-standing problem in environmental communication. Conventional charts are excellent for analysis, but research on psychological distance shows that large-scale, slow-moving phenomena such as climate change often fail to register as personally urgent when they are presented as abstract numbers. Eco-visualization, a practice first articulated in museum contexts and later explored in energy-feedback research, attempts to close that gap by blending data representation with aesthetic, narrative, and experiential elements. The catch has always been skill: designing these hybrid images demands both creative sensibility and technical competence in data processing, segmentation, and color mapping, a combination that excludes many talented designers.

The team’s answer is a structured, six-step Human-AI co-creative pipeline. The process begins with generative image creation: the user describes a dataset topic, and a text-to-image model proposes visually meaningful scenarios, such as a flooded coastal city for sea-level data or a bleached coral reef for ocean acidification. The user can accept a suggestion, request variations, or start over, iteratively steering the AI toward a contextually appropriate scene. Next comes dataset configuration, in which the user uploads structured quantitative data in CSV or TSV format; the system parses the file, displays columns as interactive chips, and pre-computes minimum and maximum values that will later define the color scale.

The third step is where the machine-learning engineering becomes visible. The system integrates Meta AI’s Segment Anything Model, or SAM, to automatically analyze the generated image and produce pixel-level masks for each identifiable object or region. Three Vision Transformer backbones of increasing size, ViT-B, ViT-L, and ViT-H, are available, but the interface deliberately hides that choice: ViT-B runs by default, and larger variants sit behind an optional advanced control. If the automatic masks miss something, a lasso tool lets users draw custom regions, and a mask editor supports merging segments through Boolean union operations, undoing recent changes, or resetting to the original output. The design philosophy is that users should evaluate the masks that matter to their visualization, not choose model architectures.

Color is treated with scientific seriousness. The system encourages palettes validated for perceptual uniformity and accessibility, such as the scientific color maps developed by geoscientist Fabio Crameri and colleagues, whose 2020 Nature Communications paper documented how arbitrary gradients can mislead viewers and distort quantitative interpretation. Users can also build custom palettes from start and end colors, and the AI suggests alternatives derived from the dominant colors of the generated image so the visualization blends naturally into its scene. During overlay generation, the chosen palette is mapped linearly onto the dataset’s value range, and the gradient is applied only inside the masked region using alpha blending, with independent hue, saturation, and lightness coefficients giving designers fine-grained control over how strongly data colors replace the original pixels. A separate edge-smoothing parameter softens boundaries between modified and untouched areas.

To understand whether this pipeline actually works for its intended audience, the researchers ran a remote user study with 13 participants, twelve of them from design backgrounds, chosen precisely because they combine visual expertise with limited experience in data-driven toolchains. Participants received no training, only a brief written introduction and a guided task: generate a mountain landscape, load monthly atmospheric CO2 data, merge masks if desired, colorize only the lake region with a scientific palette, and export the result. The evaluation combined the NASA Task Load Index for cognitive load, the short User Experience Questionnaire for pragmatic and hedonic quality, open-ended feedback, and a demographic section, all collected anonymously in compliance with GDPR.

The results were strikingly divided. Cognitive load, measured on a 0 to 100 scale, averaged 59 with a standard deviation of 16.1, squarely in the high range, and the spread suggests the mental burden varied considerably from person to person. Pragmatic quality, the UEQ-S dimension capturing usability and task effectiveness, scored a mean of minus 0.96, below the minus 0.8 threshold that marks a problematic rating. Items probing whether the system felt easy and clear scored poorly, and participants reported that the browser froze during segmentation, a consequence of running the model locally on CPU. One participant described the HSL adjustments as monotonous and struggled to grasp what the parameters actually changed, hinting that the interface failed to communicate the rationale behind its controls.

Yet hedonic quality told the opposite story, averaging 1.33, a clearly positive evaluation. Participants rated the system as highly inventive and on the leading edge, with scores of 6.23 and 5.69 respectively on those items, indicating that the core concept of embedding environmental data inside emotionally resonant imagery resonated strongly even as the interaction stumbled. The overall UEQ-S score of 0.18 landed in the neutral range, with the system’s conceptual appeal only partially compensating for its usability problems. The authors argue this gap exposes a fundamental tension in Human-AI co-creation: granting users expressive control increases creative freedom but inflates cognitive demand when the purpose of each parameter is not immediately obvious, pointing toward design strategies like progressive disclosure and contextual explanation.

The team is candid about the study’s limits. The sample was small, deliberately composed of designers, and constrained to a prescribed task with a shared dataset, so the findings speak to first-use learnability rather than open-ended creative practice. CPU-based segmentation introduced latency that degraded perceived responsiveness, and the AI’s role, while framed as collaborative, remains fundamentally reactive: it responds to prompts but does not learn from users across sessions or proactively shape the creative process, placing the current system closer to AI-assisted design than to fully bidirectional co-creation. Future work will move segmentation to GPU-accelerated or cloud inference, add contextual guidance for parameter controls, and run ecologically valid studies in which participants choose their own datasets, audiences, and visual narratives, ideally involving environmental scientists, educators, and communication professionals alongside designers.

Even with those caveats, the contribution is concrete and timely. At a moment when generative models are flooding the internet with images, this research asks a sharper question: can those models help make invisible environmental processes visible without sacrificing scientific integrity? By pairing perceptually reliable color science with iterative human steering, the pipeline sketches a workflow in which data and imagination reinforce rather than compete with each other. The mountain lake that darkens as carbon dioxide climbs is not a replacement for the chart behind it, but it is a complement that speaks to a different part of the mind, and the study’s mixed verdict, captivating concept, demanding interface, maps the road that co-creative tools must travel before that vision becomes routine practice in climate communication.
