wisePad services for vision-, hearing-, and speech-impaired users

Our vision for the wisePad system, named for the iconic three wise monkeys
that see no evil, hear no evil, speak no evil, is a full-service computing
platform designed to deliver personalized image-, audio-, and
text-transformation services to people with impaired vision, speech
captioning for people with hearing problems, and language-translation,
text-summarization, and pictographic-illustration services for people needing
help with both spoken and text-based language. 

wisePad services employ a generic head-mounted display content-transformation
device of the type described by Kanevsky and Sorenson. The device captures
image(s) on an output device (such as iPod screen, PC monitor, and projection
screen) and receives multimedia signals input from other channels. Related
wisePad services then use the service's content-transformer functions to
translate captured or received images and display them on the screen of the
device. 

wisePad transforms an image in several ways: For the vision-impaired user, it
magnifies parts of the original image to facilitate visual perception and
thus comprehension. For the hearing-impaired, it displays closed-captioned
video, pictures, and text in the lenses of the user's eyeglasses. And for
speech aid, it might transform text into simplified text in the same
language, speech into another language, speech into summary form, and/or
speech by adding pictographic icons intended to help in language
understanding in the same way pictures and icons help young children learn to
read.
