Remote selection

This method attacks the selection problem by means of direct selection. Remote object selection can be realized using ray [2,3], which is directed out of user's hand. Ray direction can be determined by user's finger, hand or head orientation. Selection is realized if ray intersects some object and the system receives command confirming object's selection. Again, this technique has disadvantage in the case when we want to select an object of very small size, that is very difficult to locate with ray. This disadvantage may be solved using so-called spotlight[*]. It employs a light cone allowing user to select very small objects aimed by directed and visible light cone.
