Abstract: A method and apparatus for performing inbuilt calibration of camera system that performs three-dimensional measurements and depth reconstruction are described. In one embodiment, the method includes displaying, using a projector of a capture device, a fiducial projection pattern in response to calibration of the capture device. The method may also include capturing, with a camera of the capture, an image of the fiducial projection pattern. The method may also include determining calibration coefficient values indicative of relative physical relationships of one or more components of the depth camera system based on analysis of the captured image of the fiducial projection pattern.

Abstract: Methods and systems may provide for an expansion card including one or more peripheral ports, a connection edge having a first bus interface and a second bus interface, and an input output (IO) controller coupled to the first bus interface and at least one of the one or more peripheral ports. The expansion card can also include an embedded controller coupled to the IO controller and the second bus interface, wherein the embedded controller has logic to receive a general purpose input output (GPIO) signal from the IO controller. The logic may also notify an off-card host device of the GPIO signal via the second bus interface. In one example, the IO controller is a Thunderbolt controller, the first bus is a PCI-e bus, and the second bus is an SMBus.

Abstract: A mechanism is described for facilitating dynamic adjustment of audio input/output setting devices at conferencing computing devices according to one embodiment. A method of embodiments, as described herein, includes maintaining awareness of proximity between a plurality of computing devices participating in a conference, detecting audio disturbance relating to the plurality of computing devices, and calculating adjustments to settings of one or more audio input/output (I/O) devices coupled to one or more of the plurality of computing devices to eliminate the audio disturbance. The adjustments may be dynamically applied to the settings of the one or more audio I/O devices.

Abstract: Apparatus, computer-readable storage medium, and method associated with speech communication, including determining whether a user is speaking, are described. In embodiments, a computing device may include a camera, a microphone, and a speech sensing module. The speech sensing module may be configured to determine whether a user of the computing device is speaking. This determination may be based upon mouth movements of the user detected through images captured by the camera. As a result of the determination, the microphone may be muted or unmuted. Other embodiments may be described and/or claimed.
