Abstract: In some examples, a computing device can include a processor resource and a non-transitory memory resource storing machine-readable instructions stored thereon that, when executed, cause the processor resource to: instruct an imaging device to capture an input image, determine image properties of the input image, activate a portion of a plurality of light sources based on a physical location of the plurality of light sources and the determined image properties of the input image, and instruct the imaging device to capture an output image when the portion of the plurality of light sources are activated.

Abstract: An example system may include a processor and a non-transitory machine-readable storage medium storing instructions executable by the processer to generate a real-time transcript of a live delivery of a presentation; provide a unique identification to an attendee within a physical proximity to the live delivery of the presentation; and provide, responsive to receiving the unique identification from a device associated with the attendee, the real-time transcript to the device associated with the attendee for display.
