Researchers at the US Caltech Institute have used augmented reality hardware and computer vision algorithms to create a new technique to guide those who have lost their vision.

The technique allows various objects found in a place to "talk" and inform the blind individual of their nature, reported the German news agency.

The new technology, dubbed CARA, utilizes different sounds to define each of the objects found in the room in order to avoid any confusion that may face the user. It also uses different sound levels to indicate the space between the user and the object. It defines the close objects with a loud sound, while it uses low sound for far objects.

CARA is worn as a portable headset, and translates the optical world into plain English audio.

The device could be used in banks, grocery stores, museums and other locations, to help blind people make their way through unfamiliar spaces.

The TechXplore website cited researcher Markus Meister, who said: "Imagine you are in a world where all the objects around you have voices and can speak to you. Wherever you point your gaze, the different objects you focus on are activated and speak their names to you.”

CARA is still in its early stages, but will benefit from the rapid development of algorithms for computer vision.

The researchers hope that places like banks, hotels and shopping malls will offer CARA devices for use by their blind customers.

Nvidia was on track to become the most valuable company in history on Thursday, with the chipmaker's market capitalization reaching $3.92 trillion as Wall Street doubled down on optimism about AI.

Shares of the leading designer of high-end AI chips were up 2.2% at $160.6 in morning trading, giving the company a higher market capitalization than Apple's record closing value of $3.915 trillion on December 26, 2024.

Nvidia's newest chips have made gains in training the largest artificial-intelligence models, fueling demand for products by the Santa Clara, California, tech company, Reuters reported.

Microsoft is currently the second-most valuable company on Wall Street, with a market capitalization of $3.7 trillion as its shares rose 1.4% on $498.

Apple rose 0.5%, giving it a stock market value of $3.19 trillion, in third place.

A race among Microsoft, Amazon.com, Meta Platforms , Alphabet and Tesla to build AI data centers and dominate the emerging technology has fueled insatiable demand for Nvidia's high-end processors.

The stock market value of Nvidia, whose core technology was developed to power video games, has nearly octupled over the past four years from $500 billion in 2021.

Nvidia is now worth more than the combined value of the Canadian and Mexican stock markets, according to LSEG data. The tech company also exceeds the total value of all publicly listed companies in the United Kingdom.

Nvidia recently traded at about 32 times analysts' expected earnings for the next 12 months, below its average of about 41 over the past five years, according to LSEG data. That relatively modest price-to-earnings valuation reflects steadily increasing earnings estimates that have outpaced Nvidia's sizable stock gains.

The company's stock has now rebounded more than 68% from its recent closing low on April 4, when Wall Street was reeling from President Donald Trump's global tariff announcements. US stocks, including Nvidia, have recovered on expectations that the White House will cement trade deals to soften Trump's tariffs.
