Abstract: A motorized tilt and swivel device that includes a motorized component and an alignment component. The motorized component is configured to receive a command signal from a camera mobile device, and place, in response to the command signal, the camera mobile device in multiple positions for capturing images. The positions include multiple rotation angles with respect to a rotating axis and multiple tilting angles with respect to a tilting axis. The alignment component is configured to substantially align, prior to receiving the command signal and based on a alignment marker, the rotating axis with a camera lens of the camera mobile device, substantially align, prior to receiving the command signal and based on the alignment marker, the tilting axis with the camera lens, and constrain the camera mobile device such that the camera lens substantially overlaps an intersection of the rotating axis and the tilting axis in each position.

Abstract: A method for controlling a field-of-view (FOV) of a camera device. The method includes receiving, in response to the camera device capturing and broadcasting an image, a plurality of FOV selections from a plurality of viewer devices, where each of the plurality of FOV selections comprises a request to adjust the FOV of the camera device, selecting, based on a pre-determined criterion, an aggregate FOV selection from the plurality of FOV selections, and generating, in response to selecting the aggregate FOV selection, a control signal for adjusting the FOV of the camera device based on the aggregate FOV selection, where the camera device broadcasts, to the plurality of viewer devices, an adjusted image captured in response to adjusting the FOV of the camera device.

Abstract: A method for object tracking. The method includes capturing, using a camera device, a sequence of images of a scene, detecting, based on a pattern of local light change across the sequence of images, a light source in the scene, comparing, in response to detecting the light source, a location of the light source in at least one image of the sequence of images and a target position within the at least one image to generate a result, and generating, based on the result, a control signal for changing a field-of-view of the camera device such that the light source substantially aligns with the target position within the field-of-view.
