Abstract: A projection controlling apparatus includes a determiner configured to determine whether a hand-held object that is an object held by a hand is present in a captured image represented by captured image data generated by capturing a projection region onto which a projector projects a projected image; and a projection controller configured to prohibit the projected image from being projected onto the hand-held object in the projection region in response to a determination by the determiner that the hand-held object is present in the captured image.

Abstract: An information processing apparatus includes: an acquirer configured to acquire (i) captured image information indicating an image captured by an image capture device, (ii) image capture position information indicating a position of the image capture device, and (iii) provisional position information indicating a position of a wearable device; an identifier configured to identify, based on the captured image information and the provisional position information, a person wearing the wearable device, from among persons indicated by one or more person images included in the captured image; a calculator configured to calculate self-position information indicating a position of the wearable device worn by the person identified by the identifier, using the image capture position information; and a transmitter configured to supply the self-position information to the wearable device. The image capture position information is higher in accuracy than the provisional position information.

Abstract: An information processing apparatus includes a first detector configured to detect an object based on captured image information generated by an image capturing apparatus; a second detector configured to, in response to the object being detected by the first detector, detect a user operation carried out with regard to the object, the user operation involving a change in a state of the object; and a display controller configured to, in response to the user operation being detected by the second detector, generate an image that is associated with the object and the user operation, to display the generated image on a display apparatus.

Abstract: A communication network system in which a CS (Circuit Switched) terminal is connected to an IMS (IP Multimedia Subsystem) via an RNC (radio network controller) and the Iu-UP (Iu-User Plane) is terminated by the RNC comprises: an IuUP negotiation result information acquiring device which requests the RNC to supply IuUP negotiation result information and receives the IuUP negotiation result information from the RNC; and an interworking device which receives the IuUP negotiation result information from the IuUP negotiation result information acquiring device and executes protocol conversion between an IuUP protocol and a protocol used in the IMS by use of the IuUP negotiation result information when a connection is made between the CS terminal and the IMS.

Abstract: To provide a media gateway device that can eliminate partition loss of internal resources of an MGW and effectively utilize the internal resources of the MGW. When starting or restarting service of an MGW, a call control management part of the MGW sends a service registration request signal to MGCs. The MGCs that receive the service registration request signal send back a service registration request response signal as a response. The call control management part registers an MGC from which a response was normally received as an object for implementation of call processing. Upon reception of a service registration request response signal from at least one MGC, the call control management part enters an in-service state. The call control management part periodically performs resending of service registration request signals only to MGCs from which a response can not be normally received.

Abstract: An interworking device includes an IuCS interface unit for an IuUP protocol signal, an Mb interface unit for an RFC3267 protocol signal, and protocol conversion means for performing protocol conversion between the IuUP protocol signal and the RFC3267 protocol signal. The protocol conversion means is connected to the IuCS interface unit and the Mb interface unit.
