The problems with all of those sign language translation gloves that keep getting media hype. Excerpt:
[A]ll the sign-language translation gloves invented so far misconstrue the nature of ASL (and other sign languages) by focusing on what the hands do. Key parts of the grammar of ASL include “raised or lowered eyebrows, a shift in the orientation of the signer’s torso, or a movement of the mouth,” reads the letter. “Even perfectly functioning gloves would not have access to facial expressions.” ASL consists of thousands of signs presented in sophisticated ways that have, so far, confounded reliable machine recognition. One challenge for machines is the complexity of ASL and other sign languages. Signs don’t appear like clearly delineated beads on a string; they bleed into one another in a process that linguists call “coarticulation” (where, for instance, a hand shape in one sign anticipates the shape or location of the following sign; this happens in words in spoken languages, too, where sounds can take on characteristics of adjacent ones). Another problem is the lack of large data sets of people signing that can be used to train machine-learning algorithms.
And while signers do use the American Manual Alphabet, it plays a narrow role within ASL. Signers use it “to maintain a contrast of two types of vocabulary—the everyday, familiar, and intimate vocabulary of signs, and the distant, foreign, and scientific vocabulary of words of English origin,” wrote Carol Padden and Darline Clark Gunsauls, who heads Deaf studies at Ohlone College, in a paper on the subject.

Also, though the gloves are often presented as devices to improve accessibility for the Deaf, it’s the signers, not the hearing people, who must wear the gloves, carry the computers, or modify their rate of signing. “This is a manifestation of audist beliefs,” the UW letter states, “the idea that the Deaf person must expend the effort to accommodate to the standards of communication of the hearing person.”
That sentiment is widely echoed. “ASL gloves are mainly created/designed to serve hearing people,” said Rachel Kolb, a Rhodes Scholar and Ph.D. student at Emory University who has been deaf from birth. “The concept of the gloves is to render ASL intelligible to hearing people who don’t know how to sign, but this misses and utterly overlooks so many of the communication difficulties and frustrations that Deaf people can already face.”

That’s not to say that Deaf people don’t have futuristic fantasies that involve technology. For example, Kolb says a dominant fantasy among her friends is for glasses that would auto-caption everything that hearing people say. Several teams of researchers are working on algorithms to make signing videos on YouTube searchable. Even more thorough, higher-quality captioning and better interpreting services would improve the lives of many.
