Visitors to the Hebridean Celtic Festival will be able to use an app to trigger online information from items such as signs and posters on the site.
Videos and band interviews will be among the online material available to view on phones and tablets.
HebCelt is is taking place in Stornoway on the Isle of Lewis from 19 to 22 July.
The Waterboys, Imelda May, Lucy Spraggan, Skerryvore, Peatbog Faeries and Dougie MacLean are among this year's acts.
HebCelt director Caroline Maclennan said: "We are offering the new augmented reality experience as an extra feature to add to the enjoyment of visiting the festival this year.
"But it will also mean people around the world can interact with the festival and capture a flavour of its atmosphere at any time.
"The message will be updated in the run up to HebCelt and during the event, allowing people to instantly access information and interviews, buy tickets and also get a taste of our unique festival wherever they are."

It made the allegations in a damning report compiled after interviews with more than 200 Rohingya refugees who fled from Myanmar to Bangladesh.
One mother recounted how her five-year-old daughter was murdered while trying to protect her from rape.
She said a man "took out a long knife and killed her by slitting her throat".
In another case, an eight-month-old baby was reportedly killed while five security officers gang-raped his mother.
An estimated 65,000 members of the Muslim minority community have fled to Bangladesh since violence broke out in Myanmar - also known as Burma - last October.
Nearly half of those interviewed by the UN said a family member had been killed. Of 101 women interviewed, 52 said they had been raped or experienced sexual violence from the security forces.
Many told investigators that members of the army or police had burned hundreds of Rohingya homes, schools, markets, shops, and mosques.
Numerous testimonies "confirmed that the army deliberately set fire to houses with families inside, and in other cases pushed Rohingyas into already burning houses", the report states.
Many victims said they were taunted as they were being beaten or raped, with the perpetrators telling them: "What can your Allah do for you? See what we can do?"
UN High Commissioner for Human Rights Zeid Raad Al Hussein said: "The cruelty to which these Rohingya children have been subjected is unbearable - what kind of hatred could make a man stab a baby crying out for his mother's milk?
"I call on the international community, with all its strength, to join me in urging the leadership in Myanmar to bring such military operations to an end."
The country's government and its de facto leader Aung San Suu Kyi have previously dismissed claims of rights abuses and insisted that the security forces follow the rule of law.
However, Ms Suu Kyi's spokesman told the BBC that the latest allegations were extremely serious. The spokesman said officials would look into them immediately.

Its mother was among the first group of 20 relocated to mid Wales from Scotland in 2015.
Pine martens were once common in Wales but were thought to be close to extinction by the 20th Century.
"Evidence of breeding in Wales is very exciting," said Hilary Macmillan from the Vincent Wildlife Trust, a mammal conservation charity.
"This is proving that they are breeding successfully in Wales."
The mother of the baby pine marten - also known as a kit - gave birth about a month ago, must have bred while in Wales to have become pregnant last year.
Others among the relocated group gave birth last year but they would have become pregnant after mating prior to their move south.
However, not everyone is please to see the animals return, with one landowner in Ceredigion dubbing the predator a "killing machine".
So far, 39 pine martens have been relocated to mid Wales in the last two years with a further 20 expected this autumn.
The kit was filmed by trust volunteer Huw Denman as it climbed a tree at its den site.
A Scottish music event is to offer festival-goers an augmented reality experience.
