The Scottish Government's tourism body has designed "a machine that tracks where you are and knows what you like" to encourage people to spend as much money as possible.
Visit Scotland's new tourism app will be supported by one of the biggest broadband projects in Europe to ensure the "machine" can also track people to remote areas.
Chairman Mike Cantley revealed the thinking behind the app at Holyrood's Education, Energy and Tourism Committee. He said: "Visitscotland.com is transforming into a digital media base that will travel with you, as long as it knows where you are.
"It needs connectivity to achieve that. The whole principle of visitscotland.com is that it will be a machine that tracks where you are, knows what you like and will be able to guide your journey and make sure, hopefully, that every visitor will spend as much as they possibly can and maximise spend as they go.
"So from that point of view it is pioneering. It does need good connectivity."
Highlands and Islands Enterprise is close to concluding a contract that involves laying 19 subsea cables to ensure connectivity extends to the Scottish islands.
Chief executive Alex Paterson said: "From our point of view, you cannot just have connectivity in Inverness, you have to have it in the islands as well. With over 1,200km of fibre optic cable to lay, it is the biggest and most complicated broadband project almost in Europe, and certainly in the UK."
But Highlands MSP Mike MacKenzie complained that the area does not have good 3G internet coverage, and is unlikely to see faster 4G coverage in the near future. He raised concerns that smartphone-reliant tourists will "fall off the map" if they venture to remote regions.
"It seems to me to be the 21st century equivalent of medieval maps that say 'here be dragons': basically 'don't go to the Highlands and Islands'," he said.
Mr Paterson replied: "People are coming to the Highlands and Islands. The population is growing, investors are coming here, so it's not quite the land of dragons. There's some good stuff there. But the point of connectivity isn't just so people can get on iPlayer. We're trying to grow our healthcare in the area, the business sector is growing, home working is growing, tourism is critically important, and they are all underpinned by good connectivity."
