Ryan Hait-Campbell says his San Francisco company's invention is really about jobs. Deaf people like himself, explains the MotionSavvy CEO, are too often shunted into positions that don't require talking to anyone--washing dishes, fishing or other solitary vocations that often have low wages, little opportunity for advancement and no need for an employer to hire an interpreter. One study found that only 58% of working-age Americans with a severe hearing impairment have a job at all. MotionSavvy's first product, though still in prototype stage, could revolutionize the prospects of millions who are deaf or hard of hearing. Called Uni, the device clasps around a PC tablet and uses MotionSavvy software to act as an interpreter between a signer (who can't speak) and speaker (who can't understand sign language) in very-close-to-real-time.
