# Accessibility and hybrid interfaces

Natural language opens some doors and closes others.

On one hand it lowers barriers: for deaf people a conversational system opens access to otherwise frustrating services. For those with cognitive difficulties, a step-by-step conversational guide is more flexible than a rigid wizard; for those moving between languages and cultures, register alignment reduces misunderstandings; for those with dyslexia or dysorthography, speaking instead of writing changes the quality of access.

On the other it raises new ones. Prompt-based interfaces load the formulation of precise requests onto the user, and the articulation barrier hits precisely the categories chat promises to include: the study of about 80 deaf and hard-of-hearing people shows that, for those with sign language as their mother tongue, **formulating effective prompts in written English is the main difficulty of use** — "as a native ASL user it takes time to build the right prompt, because the channel is only text". Automatic adaptation does not compensate (see [The conversational interface](https://www.shaped-by-ai.com/en/impacts/what-is-happening/the-conversational-interface/): models only respond to explicit requests, which those with lower literacy struggle to produce). For blind and low-vision users conversational interfaces hardly replace screen readers and mature standards; the study by Adnin and Das on 19 blind users (ASSETS '24, Northeastern University) shows that inaccessibilities — unlabeled buttons, unannounced feedback — induce erroneous mental models of the system, which distort trust calibration.

The answer is not choosing between chat and GUI, but designing hybrid interfaces: conversational and graphic elements, guided paths and direct commands, textual, vocal, and visual inputs — each user chooses the mode suited to the context and the moment.

## Effects and role responsibilities

* **[UX Researcher](https://www.shaped-by-ai.com/en/impacts/roles/research-ia/)** — Intentionally broaden the perimeter of inclusive research: low AI literacy, articulation difficulties, high cognitive pressure, different cultural and linguistic backgrounds — from the start, not as a later integration. → Useful resources: ["We do use it, but not how hearing people think"](https://arxiv.org/html/2410.21358v3); ["I look at it as the king of knowledge" (ASSETS '24)](https://dl.acm.org/doi/fullHtml/10.1145/3663548.3675631)
* **[Product / UX Designer](https://www.shaped-by-ai.com/en/impacts/roles/product-design/)** — The hybrid is not adding a chat to the UI: it requires rethinking the interaction architecture — multiple coherent paths, smooth transitions between modes, no dead ends.
* **[Content Strategist](https://www.shaped-by-ai.com/en/impacts/roles/content-editorial/)** — Content to be queried via AI (dense, explicit structure) and content to be read (narrative): the coherence between the two must be designed without sacrificing either.
