scope:

This part of ISO 9241 gives recommendations for tactile andhaptic hardware and software interactions. It provides guidance onthe design and evaluation of hardware, software, and combinationsof hardware and software interactions, including - the design/useof tactile/haptic inputs, outputs, and/or combinations of inputsand outputs, with general guidance on their design/use as well ason designing/using combinations of tactile and haptic interactionsfor use in combination with other modalities or as the exclusivemode of interaction, - the tactile/haptic encoding of information,including textual data, graphical data and controls, - the designof tactile/haptic objects, - the layout of tactile/haptic space,and - interaction techniques. It does not provide recommendationsspecific to Braille, but can apply to interactions that make use ofBraille. The recommendations given in this part of ISO 9241 areapplicable to at least the controls of a virtual workspace, butthey can also be applied to an entire virtual environment ?consistent, in as far as possible, with the simulationrequirements.
