Her computer has benn adapted with a vocalizer and a refreshable Braille display. Through this tactile medium she can talk with people online. See them, darkly, through the glass. Hear their voices, like echoes of life that resonate through the world of the dead.
None of it is real, of course. But the feel of the words at her fingertips, the texture of the Braille isplay, as familiar to her as the lines and scars on her own palm, brings with it a comfort that cannot be denied. The touchpad lets her read web pages through a series of raised pins that translate the text into a form that she can understand. She prefers it to the vocalizer; the synthetic voice is unpleasant, while the Braille display is pretty - pretty as beads, or rice in a jar, or the sound of rain on the rooftops.
