MarkO is a system that allows visually impaired people to overcome architectural barriers
using audio/tactile outputs and shared geolocalized tracks.
From the interviews and the accessible questionnaires, it emerged that visually impaired people have many difficulties when orienting and moving in a city; the sophisticated existing systems to facilitate them are rejected because they are full of redundant feedback or, like the white cane, identify the disability.
Our aim was to design a cheap and discreet system that would not identify disability and would offer a choice of whether or not to access the available information.
The application has been designed to be accessible to blind or low vision people,
using canonical interactions typical of screen readers, which they already use.
In addition, the colors used have been chosen to facilitate reading by low vision people, and communicate
for example the selection, when to speak (light screen) or when to listen (dark screen).
The device has been designed as a shortcut to allow the visually impaired
to safely access informations, tracks and the digital assistant while they are moving.
