is a person who never stops being passionately curious
and is interested in neuroscience, universal
design & inclusive public space research.
In 2010, WHO (World Health Organization) recorded
the number of visually impaired people around the world
reaches up to 285 million and set to triple by 2050.
No one can guarantee that we will not be part of that number at this time.
What are we going to prepare?

Background:
Pictogram
The forms are usually designed, read, and understood based on the representation of the form into a simplified symbol sign of the actual object.
Tactogram
Tactogram is designed based on the hierarchy of information needs by the visually impaired that are represented in geometry while they are in public spaces. The forms are read schematically through a shape discrimination technique and understood semantically.

Image: Tactogram Forms Example Use
The selection of geometric forms as a visual system is not only considered to get discriminated easily, but also it has a high precision value to be identified. Pragmatically, the system gets drawn by matching the hierarchy of information needs from the most important to the geometric shapes with the least angles.
The symbolized information gets suggested up to four kinds with its consideration is to optimize the performance of System Working Memory (SWM).
