Inclusive Technologies for Access & Social Participation

We design inclusive AI and immersive technologies that remove digital barriers, support accessibility compliance, and strengthen social participation.

Accessibility cases

We provide real-world cases that reflect everyday accessibility challenges and support the co-design of inclusive digital technologies.

AC1

Public health information

Improving access to public health and educational content for people with visual impairments, we develop AI-based tools for image description and text simplification to support inclusive publishing workflows.

AC2

Remote video-mediated language interpreting

Improving access to remote language interpreting for deaf and hard-of-hearing people, this work develops an AR-enabled service for real-time interpreting in critical situations.

Nederlands Gebarencentrum 
Berengroep
AC3

Mainstream educational resources

Focused on inclusive education, this work develops an adaptive AI companion to support comprehension and participation for children with developmental language disorders.

AC4

Adaptive therapies

Responding to the need for accessible therapies at home, this work develops embodied agents to support adaptive therapeutic practices for children with Autism Spectrum Disorder.

The Eindhoven University of Technology
AC5

Audio-visual heritage collections

Expanding access to audio-visual heritage for people with visual disabilities and deaf and hard-of-hearing people, this work develops AI-driven and object-based media techniques to enable adaptive, multimodal cultural experiences.

Translating inclusive research into digital systems

Across the Netherlands, one in four people lives with long-term visual, hearing, or cognitive impairments—barriers that too often lead to social inequality and exclusion. With the EU Accessibility Act (EAA) coming into effect in June 2025, all EU service providers will soon be required to make their products and services accessible. This landmark legislation has the potential to improve the lives of more than 135 million Europeans with disabilities. Yet many organizations remain unprepared, lacking the nuanced insights needed to design accessible, trustworthy, and socially accepted digital services.

TACIT aims to close this accessibility gap. We develop new AI and Immersive Media technologies using inclusive Human-Computer Interaction and design methodologies. Our mission is to improve the accessibility of public services, support EAA compliance, and accelerate innovation in assistive technologies.

TACIT brings together a rich, transdisciplinary consortium of intended users, researchers, knowledge organizations, and companies. Through five co-designed accessibility cases, we collaboratively explore and address the common barriers that hinder the adoption of inclusive technology.

Bringing people together around inclusive technology

TACIT is made possible by a network of partners & researchers.
