1. A smart home system comprising:
a microphone configured to detect an audio signal;
a sensor configured sense a light signal;
one or more processors; and
one or more memory devices configured to store machine-readable instructions that, when executed by the one or more processors, cause the one or more processors to:
initiate a command based on an indication, from the microphone, of detection of a particular audio signal; and
detect refraction of the light signal via a transparent material and determine an orientation relative to a source of the light signal based on the refraction;
in response to receiving a second indication of the light signal from the sensor, inhibit an action based on the command by disrupting the light signal, ignoring the command, or both.
