Abstract: An information processing apparatus comprises at least one processor that executes a program stored in a storage unit, the processor being configured to: acquire a plurality of registration information items relating to a word searched by a user; determine whether or not each of the registration items relating to the word satisfies a condition that is set in association with each of the registration information items, and derive the number of registration information items that satisfy the condition; and set a frequency of outputting a quiz relating to the word in a case where the quiz is repeatedly output to a value corresponding to the derived number.

Abstract: A central processing unit (CPU) of an information processing device acquires search history information on a word related to a question asked to a user and determines hint information related to the question to be presented to the user based on a discrimination result obtained by determining whether or not the acquired search history information satisfies a predetermined search history condition.

Abstract: An information processing apparatus includes at least one processor. The processor is configured to, based on question-giving history information on questions, identify, among users, a similar user who is similar to a target user among the users in proficiency tendency of the questions. The question-giving history information includes results of determination as to whether the users have correctly answered given questions that have been given to the users. The processor is further configured to derive a probability of the target user correctly answering a question as a deriving target question among the questions, based on a result of determination as to whether the similar user has correctly answered the deriving target question. The deriving target question is a question for which the probability is derived, and is a given question for the similar user. The processor is further configured to perform a specific process based on the derived probability.

Abstract: A remote-control apparatus includes a model information obtainer, a UI generator, and a UI transmitter. The model information obtainer obtains information indicating a model of a controlled apparatus to be remotely controlled. The UI generator generates information for displaying, on a communication terminal, a UI through which the model indicated in the information obtained by the model information obtainer is to be remotely controlled. The UI transmitter transmits the information generated by the UI generator to the communication terminal.

Abstract: According to one embodiment, a communication apparatus includes a Bluetooth (trademark) controller which is wirelessly connected to a mobile information terminal, and a CPU configured to acquire a radio-wave intensity of wireless connection to the wirelessly connected mobile information terminal, to selectively read an application program from a program memory, based on the acquired radio-wave intensity, and to execute the application program.

Abstract: A communication device includes a reception unit, a detection unit and a control unit. The reception unit receives broadcast information broadcasted through first communication of a first communication system. The detection unit detects a radio field intensity of the received broadcast information. The control unit controls second communication of a second communication system based on the detected radio field intensity, thereby activating or deactivating the second communication.

Abstract: An information output apparatus for displaying information such as advertisements increases viewers' attention. A plurality of advertisement videos (id=1, 2, . . . ) stored in an advertisement video storage area 22b are projected onto a display unit 12 from a projection device 13 and reproduced, according to the definition of advertisement video reproduction order stored in an advertisement video reproduction definition storage area 22c. Upon switching the reproduction of each advertisement video, from among a plurality of switching effect images EP . . . (ID=1, 2, . . . ) that are assigned ID numbers in descending order of noticeability against the surrounding environment, i.e. in descending order of the complementary color ratio, and stored in a switching effect image storage area 22e, an image ID associated with higher noticeability is set when the non-operation time (the time during which no person is detected around the apparatus body) from the advertisement video reproduction start is longer.

Abstract: A processor of an information transmission device generates pairing information being divided into multiple pieces according to a predetermined data structure and for starting bidirectional communication between a portable terminal and the information transmission device. The processor transmits generated pairing information being divided into multiple pieces. The processor receives a pairing request signal transmitted by the portable terminal that receives the pairing information. The processor performs a pairing operation with the portable terminal in response to the pairing request signal received.
