Abstract: An example implementation may involve driving an audio output module of a wearable device with a first audio signal and then receiving, via at least one microphone of wearable device, a second audio signal comprising first ambient noise. The device may determine that the first ambient noise is indicative of user speech and responsively duck the first audio signal. While the first audio signal is ducked, the device may detect, in a subsequent portion of the second audio signal, second ambient noise, and determine that the second ambient noise is indicative of ambient speech. Responsive to the determination that the second ambient noise is indicative of ambient speech, the device may continue the ducking of the first audio signal.

Abstract: Example embodiments include a lens having an IR-reflective coating that is selectively applied to form a variable infrared (IR) interaction pattern on the lens. The variable IR interaction pattern may vary in the manner it interacts with IR wavelengths, so as to provide a machine-readable code when the lens is illuminated by IR light. Accordingly, variable IR interaction patterns may be used to identify particular lenses. Accordingly, a glasses-style, modular, head-mountable device (HMD) may identify which of a number of different possible lenses are currently attached to the HIVID, and update certain processes according to the lens or lenses is or are attached. For example, an HIVID may calibrate an eye-tracking process according to the particular lens that is attached.
