Lighthouse Stylus: Tracking Characterization Dataset

Raw SteamVR Tracking 2.0 measurement logs, per-capture summaries and analysis code for the accuracy characterization of the Lighthouse Stylus, a low-cost open-hardware 6-DoF spatial input device. A tracker-equipped stylus mounted on a single-axis CNC carriage was driven to commanded positions across four base station configurations (1, 2, 3 and 4 stations), two sessions each, plus a separate occlusion/recovery test. The dataset backs the Validation and characterization section of the associated HardwareX article and reproduces every reported figure (scale error, jitter, repeatability, session drift, occlusion recovery). The archive also includes the Autoprobe browser application used to capture the data, so the acquisition tooling travels with the measurements. See README.md for the full data dictionary, acquisition instructions and reproduction steps.
