AI-powered BlindSpot VisionGuide system on raspberry Pi for enhancing independence of visually impaired users.
Article in Scientific reports, 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
This work describes BlindSpot-VisionGuide, an integrated, AI-based assistive system that aims to empower visually impaired people towards independence through real-time audio interaction. The system incorporates three fundamental capabilities-face recognition, image captioning, and reading online newspapers-into a voice-based platform deployable in Raspberry Pi hardware. The face recognition capability recognizes known people using deep facial embeddings and returns instant voice feedback. The image captioning module uses a transformer-based BLIP model to produce natural language descriptions of scenes captured. The online newspaper module fetches structured news content through APIs and converts it into speech through a text-to-speech engine. The voice interface is centralized for all the modules, enabling users to interact with their surroundings without their hands. The system has been tested for recognition accuracy, response time, and memory consumption on a Raspberry Pi 5. Experiments indicate that the platform operates reliably in all modules, striking a balance between computation and user-friendliness. Optimized for offline use and low-power devices, BlindSpot illustrates the practical applicability of embedded AI towards the creation of inclusive, scalable assistive technology. The authors conclude by noting potential extensions, such as object detection, multi-language support, and caregiver incorporation, making BlindSpot a fundamental model for vision-based accessibility systems of the next generation.
