Blind and deaf people will be able to more easily use smart phones, the Internet and other technologies that are staples of life and work under a bill signed into law on Friday.
Such a step has been a priority of advocates for the millions of people who cannot see or hear.
In the East Room of the White House, where he was flanked on stage by lawmakers and Stevie Wonder, President Barack Obama portrayed the occasion as another step in guaranteeing equal access, opportunity and respect for all Americans.
He recalled celebrating this year's 20th anniversary of the Americans with Disabilities Act, banning workplace discrimination against qualified people with disabilities and requiring improved access to public places and transportation.
"We've come a long way but even today, after all the progress that we've made, too many Americans with disabilities are still measured by what folks think they can't do, instead of what we know they can do," Obama said.
The new law "will make it easier for people who are deaf, blind or live with a visual impairment to do what many of us take for granted," he said, from navigating a TV or DVD menu to sending an e-mail on a smart phone.
"It sets new standards so that Americans with disabilities can take advantage of the technology our economy depends on, and that's especially important in today's economy when every worker needs the necessary skills to compete for the jobs of the future," Obama said.
In one corner of the East Room, sign language interpreters translated Obama's remarks as he spoke. Across the room, his words scrolled on a large video monitor with help from a stenographer who transcribed them.
Under the law, the quality of life will improve for 25 million people who are blind or have difficulty seeing, along with the estimated 36 million people who are deaf or hard of hearing, advocacy groups say.
Nondisabled people stand to benefit, too. They may find the devices and screens easier to use.
The law sets federal guidelines that require the telecommunications industry to:
_Make getting to the Internet easier by improving the user interfaces on smart phones.
_Provide audible descriptions of on-screen action to help the blind more fully enjoy television.
_Add captions to online TV programming to help the deaf.
_Make the equipment used for Internet telephone calls compatible with hearing aids.
_Add a button or other switch to television remote controls for simpler access to closed captioning on television.
Paul Schroeder, a vice president at the American Foundation for the Blind, said many blind or deaf people have had to spend hundreds of dollars on costly accessories or software to make their cell phones and other devices easier to use.
"We hope that companies will start working immediately on making solutions available and affordable for people with disabilities," he said.
Blind since childhood, Schroeder described the bill as "life changing."
"As a person who is blind, it will bring some of the new technologies that are changing the workplace, education and leisure into my hands," he said.
The bill is S. 3304
