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
It employs a light cone allowing user
to select very small objects aimed by directed and visible light cone.
