Perceptual space and adjective rating of 2.5D tactile patterns.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The present study investigates the human haptic perception of 2.5D tactile patterns based on adjective ratings and how physical factors, such as the bump diameter of the pattern or material, affect their tactile perception. We designed fifty tactile patterns by varying the pattern's bump diameter, pattern uniformity, and material and evaluated the effect of the parameters on haptic perception by conducting a couple of human subject experiments. In Experiment 1, the perceived intensities of the tactile patterns were tested for a total of ten properties (adjective pairs). The experimental results indicate significant effects of the factors, the bump diameter, pattern type, and material on the perceived intensities of the 2.5D patterns. In Experiment 2, a cluster sorting of the tactile patterns was conducted, and a haptic perceptual space was constructed with an MDS (multi-dimensional scaling). The results indicate a grouping of the samples by bump diameter and an effect of sample pattern uniformity for larger 2.5D tactile patterns. Overall, the present study showed that bump diameter, pattern type, and material significantly affected the perception of 2.5D tactile patterns based on the adjective ratings, and the 2.5D patterns could be grouped by the pattern's bump diameter and uniformity.
