Context

Many Deaf children are excluded from storytime because their hearing parents do not know sign language. StorySign was created to let Deaf children and hearing families read together despite that barrier.

Objectives

Use AI and augmented reality so an animated avatar can sign a storybook's text back to the reader, giving Deaf children and their hearing parents a shared reading experience.

Activities

The AI recognises text on a book page and an animated avatar named "Star" signs the story. Launched 4 December 2018 in 10 European markets and 10 sign languages (British, French, German, Italian, Spanish, Dutch, Portuguese, Irish, Belgian Flemish and Swiss-German Sign Language), the app was developed by Huawei with Aardman Animations, agency FCB Inferno, the European Union of the Deaf (EUD) and the British Deaf Association, with content licensed from Penguin Random House. It has since expanded to 15 sign languages including ASL, BSL and Auslan, and continued to receive updates as of 2024.

Results

Huawei self-reported (via Marketing Week) over 50,000 downloads, 128 million in-app film views and a £375,000 donation to deaf-literacy projects. StorySign won 4 Gold, 1 Silver and 2 Bronze Lions at Cannes Lions 2019, independently reported by ad trade press, and independent outlets (RI Global, Tech Xplore) corroborate its launch and mechanics.

Conclusions

These engagement figures are company-reported, not independently audited, and no independent academic evaluation of reading or comprehension outcomes was located. Content is also limited to a curated set of licensed titles rather than the full universe of children's books, and lead sponsor Huawei is a state-linked telecom firm - a relevant governance consideration when weighing the initiative's independence.

Implementation
Indicative cost
High (€500k–€5M) — No exact production budget given; a £375,000 donation to deaf-literacy projects plus a multi-partner production (major animation studio, ad agency, licensed publisher content, translation into 15 sign languages) implies a high-cost production for a free consumer app.
Time to results
Long (> 3 years) — Launched 4 December 2018, expanded from 10 to 15 sign languages, and continued to receive updates as of 2024 - roughly six years of continuous operation.
Staffing & skills
Huawei (corporate sponsor), Aardman Animations (production), FCB Inferno (agency), European Union of the Deaf (EUD) and British Deaf Association (content/community partners), Penguin Random House (content licensing)

Conditions for success

  • Multi-stakeholder collaboration between Deaf-community organisations, an animation studio, an ad agency and a publisher
  • Free consumer app removing cost as a barrier to access
  • Continued content updates and language expansion (10 to 15 sign languages) sustaining relevance

Common failure modes

  • Content limited to a curated set of licensed titles rather than the full range of children's books
  • Huawei, as lead corporate sponsor, is a state-linked telecom firm - a relevant governance consideration for the initiative's independence

Where it fits
