Abstract
A technique includes sensing energy emitted from an object using an omnidirectional antenna of electronic device and sensing the energy using a unidirectional antenna of the electronic device. The technique includes, based at least in part on the sensing of energy using the omnidirectional antenna and the sensing of the energy using the unidirectional antenna, determining whether an image of the object is displayed in a camera viewfinder of the electronic device. The technique includes selectively causing the electronic device to generate an output based at least in part on the determination.
