Abstract: In the metaverse space display device, the first display means displays a two-dimensional metaverse space including a two-dimensional avatar and a two-dimensional virtual object. The second display means displays a three-dimensional metaverse space including a three-dimensional avatar and a three-dimensional virtual object. The reception means receives an operation from a user. The display control means performs switching to the display by the first display means or the display by the second display means based on a content of the operation.

Abstract: In the context prediction device, the state information acquisition means acquires state information regarding a plurality of avatars and a plurality of virtual objects. The motion information acquisition means acquires motion information regarding the plurality of avatars and the plurality of virtual objects by user operations. The behavior recognition means recognizes behaviors of the plurality of avatars based on the state information and the motion information. The prediction means predicts contexts regarding the behaviors of the plurality of avatars based on the state information, the motion information, and the behaviors of the plurality of avatars.

Abstract: A moving body includes an input/output part that receives an encryption key from a transmission apparatus and transmits the encryption key to a reception apparatus; a storage control part that controls storage of the encryption key in a storage part; and a movement control part that moves the moving body to the reception apparatus after receiving the encryption key from the transmission apparatus, wherein the storage control part stores the encryption key in the storage part upon receiving the encryption key from the transmission apparatus and erases the encryption key stored in the storage part in a case where an abnormality is detected.

Abstract: At least one processor included in an information processing apparatus carries out: an acquisition process for acquiring input information; a derivation process for deriving at least one selected from the group consisting of a first response time, which is required for a first language model to generate first response information, and a second response time, which is required for a second language model to generate second response information; and a determination process for determining response content with respect to the input information with reference to the at least one selected from the group consisting of the first response time and the second response time which has been derived in the derivation process.

Abstract: In a search system for searching a database based on a keyword input from a portable terminal while outputting a result of the search to the portable terminal to display, there are provided a search server that searches the database for information including the input keyword, a degree-of-popularity calculating apparatus which acquires number-of-member information from an i-Mode® server having the number-of-member information on the number of members for each menu in which various webpages are sorted for each category thereof, and calculates the degree of popularity of the menu based on the acquired number-of-member information, and information ranking means for ranking a plurality of pieces of information searched by the search server based on the degree of popularity of the menu to which the information belongs generated by the degree-of-popularity calculating apparatus.
