ISO 9241-920:2009
Ergonomics of human-system interaction -- Part 920: Guidance on tactile and haptic interactions
Product Details
It does not provide recommendations specific to Braille, but can apply to interactions that make use of Braille.
The recommendations given in ISO 9241-920:2009 are applicable to at least the controls of a virtual workspace, but they can also be applied to an entire virtual environment — consistent, in as far as possible, with the simulation requirements.
NOTE It is recognized that some interactive scenarios might be constrained by the limitation that a real workspace is to be modelled in a virtual environment. Objects can be in suboptimal positions or conditions for haptic interaction by virtue of the situation being modelled.
