Development of an Accessible Laptop with a Braille Tactile Interface and Voice Command System for Users with Visual Impairments

Abstract

Visual impairment, ranging from partial limitations to total blindness, remains one of the most critical challenges to digital and social inclusion in Brazil and worldwide. Despite legal advances in the country, such as the Brazilian Inclusion Law, significant barriers still hinder access to digital technologies for visually impaired individuals. This paper presents the development of an accessible laptop featuring a tactile interface and voice commands, aiming to promote autonomy and digital inclusion for visually impaired users. The initiative was carried out through a partnership between two Brazilian companies and applied methodologies such as the decision funnel model, Design Thinking, and a structured product development flow. The project included the construction of a physical prototype with an ABS casing, Braille-labeled keyboard, proximity and location sensors, as well as software with voice command functionality and native OS integration. The proposed solution proved effective in overcoming technological challenges, contributing to a more inclusive digital environment in line with legal frameworks and current social demands.
