mobile app converts spoken words into printed stickers with braille for the visually impaired

mobile app lets the visually impaired print labels

Concept Nemonic Dot comes in two: a printer and a mobile app that converts spoken and typed words into printed stickers and labels with Braille for the visually impaired. With this, users can create labels by typing or using voice input, and the app also provides contextual keyword suggestions, which helps reduce mistakes and improves clarity. Because the translation is handled automatically, users do not need to understand Braille rules or formatting.

Once the text is ready using the mobile app, the accompanying device produces Braille using a proprietary pressing mechanism, which creates raised dots that are 0.6 millimeters high, matching international Braille standards. The uniform height and spacing of the dots ensure that the Braille is comfortable and easy to read for the visually impaired users. The printer itself is designed to be used without sight, so its physical form uses tactile textures, allowing the visually impaired users to operate it independently after using the mobile app.

Compact printer uses pressing mechanism for the braille

Aside from the dedicated mobile app, the design of the printer is user-friendly for the visually impaired. In fact, the design team at Mangoslab says that loading cartridges, aligning materials, and activating printing can all be done through touch. The machine features an eyes-free design to support the full independence of the users and avoid the need for assistance. The device is also battery-powered and connects to a smartphone via Bluetooth, so it does not need a fixed workspace or wired setup. 

This makes it suitable for homes, pharmacies, schools, offices, and public buildings, and its compact size allows it to be carried and used in daily routines, such as labeling food, medicine, documents, or equipment. Once applied to the real-world scenarios, both the mobile app and the printer can help the visually impaired be more aware of the labels around them. They can print the expiration dates for their food, mark their household items, and even label their personal items. The team behind Nemonic Dot, the Mangoslab, introduced the compact device at CES 2026 in Las Vegas, and so far, there’s no news yet on the concept device’s potential availability.
