An image of a scene may be observed, received, or captured. The image may then be scanned to determine one or more signals emitted or reflected by an indicator that belongs to an input object. Upon determining the one or more signals, the signals may be grouped together into a cluster that may be used to generate a first vector that may indicate the orientation of the input object in the captured scene. The first vector may then be tracked, a virtual object and/or an avatar associated with the first vector may be rendered, and/or controls to perform in an application executing on the computer environment may be determined based on the first vector.
