We present an idea that uses a tracked graphics tablet attached a virtual or physical object to grasp in VR for direct 3D sketching on virtual objects, giving users the feeling of holding a physical object and drawing on it. We developed a prototype system and evaluated the effect of different tablet manipulation modes on user performance and experience when drawing strokes on virtual objects in VR. Results suggested that having a physical handle or object to grasp enhanced the participants' sense of realism, compared to conditions where there was no tablet or a simple tablet interface.
