Overview

I collaborated with Sky Glass as part of a cross-functional project to develop Clear Subtitles, an accessibility-focused caption enhancement designed for viewers with dyslexia. The concept introduced improved readability through clearer typography, layout adjustments and personalisation options to support a more inclusive viewing experience. 

My contributions included user interviews, accessibility research, journey mapping and iterative usability testing with input from Sky’s innovation and accessibility teams.

The Problem

Sky Glass’s existing subtitle experience lacked accessibility features tailored for dyslexic users, limiting readability, personalisation and ease of use.

The Solution

Clear Subtitles is an accessibility-focused caption experience designed around the specific needs of dyslexic viewers. 

Key improvements included clearer text presentation, adjustable sizing and colour options, and a more intuitive controls layout to enhance readability and comprehension.
