A museum in the Netherlands is trying to show visitors more of the objects it has and bring them more excitement.It is using an augmented reality（增强现实）device made by Microsoft to reach its goal.However,the use of this high-technology device started with a basic problem.

The Dutch National Museum of Antiquities does not have enough space to put all of its artifacts（人工制品）on display.So,the museum asked experts at Delft University of Science and Technology to find a way to let more visitors—especially young people—experience what the museum has to offer.

The experts used the Hololens（全息透镜）.It is a computer that shows visitors holograms,or virtual pictures that appear to have three dimensions.

Annelies Maltha,a researcher at the University,says that almost 80 percent of the artifacts at the museum are not shown to the public."So by using the Hololens,"she adds,"people can virtually visit the exhibit and see so much more."

The Dutch National Museum has artifacts like the Egyptian Temple of Teffeh.The structure was reconstructed inside the museum in 1971.It is not currently available to the public.

"The Hololens enables you to have augmented reality,instead of virtual reality,which means you can still see the temple,you can still feel the ancient vibe（氛围）around you,so to speak."The augmented reality technology gives visitors the ability to interact with their surroundings.

The researchers are using the Hololens to make three dimensional images of every room in the temple.Erik Hoglund,another researcher,explains that his team can create 3D models and add different images,movies,or animations.The effect is to make visitors feel like they are interacting with the temple.

The Hololens program is still being developed.But museum officials hope that,in the future,the Hololens will serve as a tour guide for exhibits that have been hidden from public view.
