Abstract: A display system may include a display, a first server transmitting first content to the display device, a second server receiving the first content from the first server, and a camera transmitting second content obtained by capturing images on the display, to the second server. The second server may be configured to determine whether a rate at which the first content coincides with the second content is greater than or equal to a specified value, by comparing the first content with the second content. The second server measures a first time period during which a region of the captured images corresponding to the first content coincides with the second content at a rate which is greater than or equal to the specified value. Advertising costs are calculated based on the measured first time period.

Abstract: A display system includes a display device including a plurality of displays to output first content received from a first server, a second server to receive the first content from the first server and to store a plurality of error patterns which is able to occur in the first content, and a photographing device to transmit second content obtained by photographing the display device to the second server. The second server displays whether a defect is present on the display device, by comparing the second content with the plurality of error patterns, when the second content is received from the photographing device.

Abstract: An integrated collaboration platform with various communication and collaboration tools includes an analytic engine to perform communication and mood analysis of conversations among other analyses. The platform enables a method for contextual communication, in an embodiment. The method for contextual communication involves receiving an indication of sending a message from a sender to a recipient, understanding the topic of the message, analyzing various parameters associated with the sender and the recipient, and suggesting a list of messages, information, alternate communication channels, desired moods for the receiver at the time of receiving the message, and timing of delivery of the message for a desired response from the recipient.
