Claim 0:
1. A computing device comprising:
a speaker;
at least one storage device;
instructions; and
at least one processor to execute the instructions to:
cause the speaker to produce a series of pulses, successive ones of the pulses spaced at first intervals during a first time period;
process noise information to determine whether an object is within an activation region associated with the computing device, the noise information output by a microphone, the noise information representative of at least some of the pulses and echoes of the at least some of the pulses reflected off surfaces in a vicinity of the computing device;
in response to detection of the object within the activation region during the first time period, cause the speaker to produce an additional series of pulses spaced at second intervals during a second time period after the first time period, the second intervals being shorter than the first intervals; and
verify the object is within the activation region based on additional noise information during the second time period.
