Thanks for your answers:)

That's true. So yes, if you are interested in a CV based approach, then those capabilities are available.

It's easy enough to trigger a video player when a target is detected, but registering the video image to a target is more of a challenge.

Here is a description of some of the options - http://ar.qualcomm.at/node/2002156

You can also search the forum for 'video texture' to review the current discussions on this topic.

My goal is to make indoor "Layar" with high quality 3d models, video, audio and text data for each point of interest. So I want to know is there any way to show video data in vuforia unity extension application? I'll be glad for any help.

That's not true. Layar can also Vision based Augmented Reality (Layar Vision).

Layar and Wikitude are location based AR frameworks. They use latitude, longitude, and altitude data to position and scale elements on screen. Vuforia is a computer vision based AR SDK. It doesn't provide access to location data, or features for positioning elements based on their relative location. You'd need to develop these facilities yourself.

Have you been through the Unity virtual buttons sample yet?

I want to have for example one image target with image buttons. Each button bind to different type of informatio: 1st - 3d model, 2nd - text, 3rd - video etc.

So basically you want to have multiple data sets, each with a set of images that give different results with text/audio and video - right?

However, it seems you probably want to be able to download these datasets which is a bit more involved then including them statically within Unity.

Theoretically it should be possible - search the forums as others are trying this also.
