AI summary

A user control apparatus has a laser emitter that emits a laser beam in a real-world environment. Further, the user control apparatus has an optical element that receives the laser beam and generates a plurality of laser beams such that a starting point and a plurality of endpoints, each corresponding to one of the plurality of laser beams, form a laser frustum. In addition, the user control apparatus has an image capture device that captures an image of a shape of the laser frustum based on a reflection of the plurality of laser beams from an object in the real-world environment so that a spatial position of the object in the real-world environment is determined for an augmented reality or virtual reality user experience.
