VISION by Metron Ariston™
About VISION
VISION by Metron Ariston™ is a pioneering Greek initiative that brings inclusion to the forefront of contemporary hospitality. It aims to make hospitality venues — from bars and restaurants to cafés and hotels — more accessible to people who are blind or visually impaired.
Developed by Metron Ariston – Making Responsibility a Trend, with the voluntary scientific contribution of advisors.
Placing Human-Centered Innovation first, VISION is based on hybrid (audiovisual) catalogues narrated by distinguished radio personalities and actors. It promotes autonomy and integration within the everyday culture of going out.
Now entering its Pilot Phase I across 12 top-tier venues in Greece, VISION combines human-centered design with a fully integrated feedback mechanism to support continuous improvement. More than a tool, it is a living system of inclusion.
Mission
Redefining Hospitality as a Cultural Right
VISION by Metron Ariston™ aspires to become an international benchmark — redefining hospitality as a shared cultural right: accessible, respectful, and deeply human.
Vision
Expanding Inclusivity Through Shared Feedback
In its next stage, VISION will broaden its scope to address additional forms of disability. Guided by shared feedback and suggestions from users, experts, and the community, each proposal will be carefully assessed, and if proven both feasible and beneficial, implemented.
This continuous evolution ensures that VISION remains not only innovative but also responsive — adapting to real human needs and shaping the future of inclusive hospitality.

Through Metron Ariston she initiated VISION by Metron Ariston™, an evolving initiative that promotes accessibility within bars and restaurants—beginning with inclusive catalogues and audio tools for visually impaired guests.

A passionate traveler who has visited more than sixty-four countries, she continues to explore how food and drink tell stories of people, place, and purpose.

“The natural human voice surrounds and embraces the person to whom it is addressed, with the warmth of prosody and human timbre.
Thus the distance of the artificial voice disappears, and what comes to the forefront is human speech addressed to another human being — another form of language, another form of warm communication.”
