Talking Though Her Nose

Ed Yong describes a device that allows severely paralyzed individuals to write via sniffing. The gadget's first user is referred to as "LI1":

LI1 is one of the quickest users and she only manages around three letters per minute, with one mistake with every six letters. That’s may seem frustrating but the freedom of expression more than makes up for it. As Plotkin and Sela write, “The speed of this self-expression is less important to individuals who, put bluntly, have no other options.” When LI1 and LI2 were asked to suggest improvement to the controller, neither mentioned speed.
