Looking at the benefits derived from the multiple ways that technology can connect people who are blind to the world, David likes to consider this connection in a holistic way. He prefers to view those connections within the inclusive mental model he calls a
Philosophy of Barriers.
This is considered within 4C thinking:
C1 Competencies (or skills)
one needs as a blind person,
you develop confidence because you develop skills,
with others, and
where you introduce skills blind people need to succeed in life.
All together these make positive change possible and technology’s role, incalculable. Technology forms a circle of support within those areas as it opens up the world to blind people. Technology’s role is a very powerful one to support the relationship with that world.
