MULTI-MODAL FAR FIELD USER INTERFACES AND VISION-ASSISTED AUDIO PROCESSING
Far field devices typically rely on audio only for enabling user interaction and involve only audio processing. Adding a vision-based modality can greatly improve the user interface of far field devices to make them more natural to the user. For instance, users can look at the device to interact with it rather than having to repeatedly utter a wakeword. Vision can also be used to assist audio processing, such as to improve the beamformer. For instance, vision can be used for direction of arrival estimation. Combining vision and audio can greatly enhance the user interface and performance of far field devices.

CIRCUITS AND TECHNIQUES FOR ENHANCED SPI DAISYCHAIN
The present subject matter facilitates chaining of multiple serial peripheral interface (SPI) compliant devices without requiring a bulky clock tree. Generally, in a serial clock distribution scheme as described herein, a fixed pulse based output cock (SCLK_OUT) is synchronized with the data output (SDO) from a respective device in the chain. The SCLK_OUT signal is connected to the SPI clock input (SCLK) of the following downstream device, and SDO is connected to the data input (SDI) of the respective downstream device. This allows the SCLK from the SPI master device to propagate through a theoretically unlimited count of devices in series. The master can resynchronize the MISO data from the SDO of the last part in the chain with the SCLK_OUT signal of the last device in the chain.
