Abstract: A control device (500) includes a selector (550) that selects one of a first vehicle and a second vehicle as a remaining vehicle that stores a first article and a second article and that remains at a receiving location where the first article and the second article are to be received, and selects another of the first vehicle and the second vehicle as a departing vehicle that departs from the receiving location, when the second vehicle storing the second article arrives at the receiving location while the first vehicle storing the first article stays at the receiving location. Additionally, the control device (500) includes a storage controller (560) that identifies the first article or the second article stored in the selected departing vehicle as a transfer article to be transferred from the departing vehicle to the remaining vehicle, and causes the identified transfer article to be stored in the remaining vehicle. Furthermore, the control device (500) includes a movement controller (540) that causes the departing vehicle to depart from the receiving location when the transfer article is stored in the remaining vehicle.

Abstract: Provided is a package reception management system including a delivery vehicle configured to move in an unmanned operation. The package reception management system is configured to: acquire a reception region in which a package transported by the delivery vehicle is to be passed to a user being a delivery destination; issue authentication information to be input to the delivery vehicle in the reception region by the user being the delivery destination; and to notify the user of the issued authentication information. In the issuing, the package reception management system sets information for restricting later issuing of the issued authentication information for the reception region, and restricts issuing of the same authentication information as at least one piece of authentication information restricted in the issuing for the reception region.

Abstract: A sensor unit (105) included in a display device (100) detects a shift in orientation of a display (104) included in the display device (100) in a real space. A display control device configured by a control unit (101) changes the sight line direction in a virtual space, which includes a plurality of still and moving objects, in accordance with the detected shift in orientation, and generates an image representing a view of the virtual space in the sight line direction. The generated image is displayed on the display (104). The display control device configured by the control unit (101) then specifies a focus object among the objects, transfers an observation site about the focus object in the direction opposite to the direction of change in the sight line direction, and then generates the image of the virtual space from the observation site in the sight line direction.

Abstract: Identification means of an information processing system identifies, based on an action history of each of a plurality of users, a plurality of data items having a degree of action equal to or more than a predetermined degree. First information acquisition means acquires, based on the action history of each user, first information indicating relevance between the respective data items identified by the identification means. Output means outputs, when details of each of the plurality of data items are input, second information indicating relevance between the respective data items based on a predetermined parameter. Setting means sets the parameter based on the details of each data item identified by the identification means and the first information.

Abstract: An airspace is appropriately allocated when the airspace is allocated to an unmanned aerial vehicle. Authority level acquisition means of an airspace management system acquires, for each unmanned aerial vehicle, an authority level of an operation of the unmanned aerial vehicle. Airspace level acquisition means acquires, for each airspace occupying a fixed range, an airspace level indicating an allowable range of the authority level in the airspace. Determination means determines whether or not the unmanned aerial vehicle can fly in a given airspace based on the authority level and the airspace level.

Abstract: Provided are a content sharing system, a content sharing method, and a program, which are capable of appropriately processing an operation of a user on shared content after scrolling by an operation of another user is performed. An estimated scroll amount identification module identifies an estimated scroll amount during a predetermined time period until a timing t3 based on a scroll amount of the shared content by the operation of another user performed before a timing t2. An actual scroll amount identification module identifies an actual scroll amount during the predetermined time period until the timing t3. An object corresponding position identification module identifies a second position, which is separated from a first position by a difference between the actual scroll amount and the estimated scroll amount. An object processing execution module executes processing on an object associated with the second position.

Abstract: A landing management device sets a partition, in a predetermined landing area, on the basis of information of an unmanned aerial vehicle that lands on a landing area, the partition being obtained by virtually partitioning a part of the landing area, and transmits landing control information to a control device, in order to make the unmanned aerial vehicle land on a partial area corresponding to the partition. The control device controls landing of the unmanned aerial vehicle on the basis of the landing control information received from the landing management device.

Abstract: An efficient encoding/decoding method for block compression for RRR, provides an area-saving method that operates at high speed even with a dense bit string. A block encoding device generates blocks having a first block length by dividing an input bit string into a plurality of blocks, determines a first weight of each block from the number of 1 values included in the bit string, divides each block into small blocks having a second block length, determines a first order of the blocks in a set in which predetermined bit strings having the first block length and the first weight are arranged in a predetermined order on the basis of the weight and value of each of the small blocks, and generates block encoding data by converting the bit string of each block into the values of the determined first weight and first order.
