The International Symbol of Access (ISA), used to denote a facility which has been designed with accessibility or people in wheelchairs in mind. Broadly depicted as a white graphic of a person sitting in a wheelchair facing rightward, overlaid on a blue square background. 

Originally designed in 1968 by Danish design student Susanne Koefoed. However, most platforms now use an Accessible Icon Project-style image for this emoji, displaying the person in the wheelchair in a more active position to emphasize independence and movement.
