History buffs can now crawl through the Marsiling Tunnels, used by the Japanese during World War II, all from the comfort of their computer screen.

The National Heritage Board (NHB) struck an agreement with Google Singapore which allowed the agency access to its Google Glass prototype - a lightweight eyewear computer which lets wearers film what they see.

NHB researcher John Kwok, 36, wore the glasses as he clambered through the entrance to the 70-year-old tunnels and filmed a six-minute video which was uploaded to the board's YouTube channel on Wednesday

It is the first in a series of nine NHB videos to be filmed using Google Glass technology.

NHB is the first public sector agency here to gain access to the prototype, which it can borrow from Google Singapore as and when it needs to.

The board's group director of policy Mr Alvin Tan said there are plans to film videos of the Tiong Bahru Air Raid Shelter and artefacts from the National Collection that are housed in the Heritage Conservation Centre in Jurong.

Mr Tan said: "NHB is excited by the possibilities of using Google's wearable technology to facilitate the documentation of Singapore's heritage, and to increase the accessibility of heritage resources by bringing the heritage experience to anyone who has Internet access."

Google Glass retailed for about S$1,900 when it went on sale for a day in the United States last month. It is yet to go on sale in Singapore.
