Abstract: An approach is provided in which the approach establishes a geo-fence around a user in response to the user invoking a video conversation corresponding to a conversational context. The approach determines an action in response to detecting an entity crossing the geo-fence. The action is based on the entity and the conversational context of the video conversation. The approach invokes the action by transmitting a message to a device in proximity to the entity.

Abstract: Disclosed embodiments provide techniques for data communication to mobile electronic devices utilizing nodes equipped with directional transmitters. The mobile electronic devices are classified as registered or unregistered. A current location for each mobile electronic device in an area is determined. A registered mobile electronic device is identified from a group of mobile electronic devices. Based on the determined location, a distance to a registered mobile electronic device from a transmitter is determined. The transmitter is a directional transmitter, capable of transmitting along a sector. A sector corresponding to the registered mobile electronic device based on an angle range and distance from a transmitter to the registered mobile electronic device is determined.

Abstract: Embodiments of the invention provide a method, system and computer program product for viewport selection for hypervideo presentation. In a method for viewport selection for hypervideo presentation, a multiplicity of different hypervideos, for example 360° hypervideos, are played back to an end user and end user interactions by the end user with each of the different hypervideos are recorded. Then, an end user profile for the end user is computed from the recorded end user interactions so as to specify a particular viewport. Finally, in response to a directive by the end user to view a new hypervideo, the end user profile is retrieved and the particular viewport identified so that the new hypervideo is played back to the end user utilizing the particular viewport.

Abstract: A method for placing a linked hyper-video within a hyper-video. The method includes identifying one or more points of interest in the hyper-video, detecting one or more features of the hyper-video, extracting at least one of the one or more features, and displaying the linked hyper-video, within the hyper-video, based on the one or more identified points of interest and based on the extracted at least one of the one or more features. The method further includes extracting one or more features from the hyper-video that depict one or more viewing characteristics of a user. The method includes analyzing the one or more features from the hyper-video to identify a low-saliency area of the hyper-video, a low-frequency region within the low-saliency area, and a homogenous sub-region within the low-frequency region. The method further includes placing a linked hyper-video at the homogenous sub-region within the low-frequency region of the hyper video.
