Low-cost head-mounted camera system for medication-error detection.
Article in HardwareX, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
We present a low-cost, reproducible head-mounted wearable system for first-person video capture and real-time medication-workflow monitoring. The device combines a Raspberry Pi Zero W, Pi Camera Module v3, PiSugar 2 Pro battery board, active buzzer, tactile push button, and a modular 3-D-printed PLA enclosure with elastic head straps. Weighing approximately 145 g and costing about USD 100 for the core wearable components (USD 168.78 for the complete development and configuration bill of materials), the system is designed for offline operation, local storage, and low-power embedded processing. The enclosure was modeled in DesignSpark Mechanical and fabricated as modular panels with integrated mounting, ventilation, and access features. The software stack runs on Raspberry Pi OS Lite with Python/OpenCV scripts for autonomous capture, local event flagging, and audible feedback. Pilot deployment confirmed stable operation, up to 7 h of battery-powered use, and practical wearability in clinical settings. This work provides a reproducible open-hardware platform for wearable monitoring in low-resource operating room environments.
