Example: A Matching TestExample: A Matching Test

We are currently working on a small We are currently working on a small example of a VR application developed example of a VR application developed using the InTml framework.using the InTml framework.

In this application, the user must match In this application, the user must match pairs of objects in a 3D environment. The pairs of objects in a 3D environment. The interaction techniques used must be interaction techniques used must be appropriate to the environment the user is appropriate to the environment the user is working within.working within.
