Research process

Problem statement

Traditional visual learning materials limit access for students with visual impairment. The thesis proposes a tactile-visual substitution system that translates patterns into touch-based experiences.

The system targets classroom use, where educators need consistent tactile output and straightforward teaching workflows.

Objectives

Design and build a tactile device capable of rendering patterns safely and consistently.

Enable educators to create, store, and playback learning content through a mobile workflow.

Validate usability and tactile perception with inclusive education partners.

Methodology and partnerships

The project follows a user-centered engineering approach with iterative prototyping and validation.

Collaboration with DECSEDIV informs safety decisions, content formats, and classroom readiness.

Theoretical framework

The research draws on sensory substitution theory, haptic perception, and tactile learning methodologies.

The design aligns with assistive-technology best practices for safety and accessibility.
