Product: Personal Shelf Inspector

Personal Shelf Inspector is an application that helps visually impaired people during their day-to-day shopping. The application is based on a similar neural network as our product Shelf Inspector for retail supermarket chains and retail producers.

Business case

Globally the number of visually impaired people of all age groups is estimated to be over 285 million, of whom 41.1 million are blind. (WHO, 2020)

We decided to build and provide several free tools that make shopping for visually impaired people more accessible. These tools can be implemented in any retail chain within the loyalty app or directly in-store.

Our solution

A visually impaired person only needs their smartphone to use our tools. Personal Shelf Inspector works as a web application that reads the price and product name from a price tag. The algorithm selects the price tag closest to the centre of the photo and sends it to the model, which reads the price and product name on the price tag. Then it returns this information back to the application, where it appears as text on the screen.

The voice-over built in the user's mobile phone reads this text aloud. Our app also helps to read the banknote values and read from a live video.
