pressR parses, analyzes, and visualizes pressure distribution data from capacitive sensor systems. It ships with predefined layouts for in-shoe pressure measurement, saddle pressure mapping (equine and bicycle), seating assessment, and barefoot pedography, along with an interactive Shiny application for data exploration.

pr_calc_regional(trial)- Parsers for ASCII pressure data exports, generic CSV, force
sensor data, and region mask files (
.msa/.msr/.msp). - Predefined layouts for in-shoe insoles (99-sensor), barefoot pressure platforms, generic sensor mats (16x16 / 32x32), horse and bicycle saddles, wheelchair / car / office seating, and glove sensors.
- Per-frame and per-trial analysis: peak pressure, mean pressure, force, contact area, pressure-time integral, center of pressure, symmetry index, gait cycle detection, and COP rollover pattern.
- Application-specific analysis: saddle bridge and slip detection, wheelchair hotspot identification, plantar-pressure regional analysis.
- Published reference thresholds for saddle fit (von Peinen 2010, Moenkemoeller 2005, Werner 2002), diabetic foot risk, and wheelchair seating.
- Visualization: 2D and 3D heatmaps, dynamics plots, regional bar charts, composite report panels, and side-by-side trial comparison.
- Shiny app (
pr_run_app()) for interactive import, analysis, and export.

Where applicable, LLM tools were used for narrowly defined, non-authorial tasks: copyediting, prose refinement, Markdown/LaTeX formatting, boilerplate scaffolding (such as CI configurations and build scripts), and code refactoring. Tools included Chat AI, the KISSKI (GWDG) service, and self-hosted Mistral Small (24B, Apache-2.0) served through a local vLLM architecture on an Ubuntu Linux workstation with Intel processors and NVIDIA GPUs. The self-hosted model ran locally, with no data sent to third parties.
All scientific claims, methodological choices, analyses, interpretations and conclusions remain the authors' own. Where applicable, LLM-generated material must be reviewed and revised before inclusion, and references must be verified against their DOI, arXiv ID or ISBN.
Local software setup: vLLM with Python/PyTorch, plus R and RStudio.
