Techniques are described that enable a virtual laser pointer with an adjustable conical laser. The adjustable conical laser includes a main ray, like a conventional virtual laser pointer, but also provides a conical laser that expands the user’s target area. When the user misses the intended target with the main ray, the VR system can use the cone to determine the likely target. If the cone intersects a single object, the VR system selects that object. If the cone does not intersect any objects, the VR system can expand the cone and determine if any objects intersect the expanded cone. If the cone intersects multiple objects, the VR system can determine the angles from the main ray to each intersection and select the object with the smallest angle. The angle of the conical laser can be manually adjusted to suit the user’s preferences and the particular VR experience.
