Project: BrailleTouch: Automatic Error Correction for Text Entry on Touchscreen Tablets
(with Harish Kothandaraman, Sudarsanan Krishnan, Joe Lin, Vignesh Somasundaram)
Text entry on flat glass with no tactile landmarks is challenging, particularly when not looking at the
screen. In previous work on BrailleTouch, I observed that blind users' hands tend to drift over time
as they enter braille chords on a touchscreen, introducing typing errors. We designed and implemented
two strategies for automatic correction of these errors:
(1) an adaptive algorithm in which the soft buttons follow the user's hands through moving averages of
the previous touch locations; and (2) a predictive algorithm which interprets the user's intended
input word through the number of touches in each braille chord, the number of letters in the word, and
the hamming distance from words in a dictionary. We evaluated these algorithms against raw touch event logs
of the natural patterns of blind users typing braille on an Android touchscreen tablet. This work has applications for ubiquitous text entry
and other multi-touch interactions on any flat surface instrumented for touch input.
