Abstract: A method, apparatus and computer program product are provided to facilitate interaction with a computing device, such as interaction with an object viewable via a display of a computing device. In the context of a method, an object viewable via a display is identified, such as by facial recognition. The method also includes determining that the object has become aligned with an operation indicator as a result of movement of the display relative to the object. In response to determining that the object is aligned with the operation indicator, the method also performs an operation associated with the operation indicator. In this regard, a method may perform the operation upon at least one aspect associated with the object. Corresponding apparatus and computer program products are also provided.
