Manipulate object on a tablet

I’m a Unity & C# beginner.

I would like to develop the tablet application by Unity, which can freely show some polygon model such as a person.
You know it is possible to manipulate a GameObject freely like movement, rotation and zooming using Gizmo on the Scene View in Unity.
I would like to do it on a tablet.

Can you give me some scripts or advices about it?
Thank you for your consideration!

Search for “unity3d touch orbit” and you will probably find something.
