Abstract: A driving characteristic determination device includes a hardware processor connected to a memory. The processor detects driving information indicating at least one of driving behavior for a vehicle by a driver, biological information of the driver during driving, and behavior of the vehicle. The processor calculates, on the basis of the driving information, numerical values indicating whether a cognitive function of the driver is high or low. The processor analyzes the numerical values indicating whether the cognitive function is high or low. The numerical values are analyzed as cognitive function characteristics relative to one or more different brain functions. The processor outputs information about an analysis result obtained by the analysis of the numerical values.

Abstract: When it is appropriate to switch communication method, a portable terminal enables the notifying of a user of conditions. On the basis of visited network identification information acquired from a mobile communication system, the control section of the portable terminal displays a message on a display for alerting the user when there has been a switch in communication method from 3G to GSM. At this time, the change in visited country wherein the portable terminal is currently located is determined, and after displaying the message, the display of the message is suppressed until the visited country changes. That is, by only displaying the message when network switching occurs when changing the visited country and the visited network changes to a GSM network, alerts are prevented from being displayed more than necessary.

Abstract: There are provided a communication apparatus and a communication method that enable notification of caller information in an oversea call. A portable phone 100 that is an example communication apparatus has an operation section 16 for accepting an operation input; a storage section 13 for storing information showing a location of the portable phone 100; and a control section 17 for effecting control so as to make a voice phone call with an addition of a predetermined message in accordance with the information when the operation section 16 instructs voice phone call.

Abstract: It is an object to provide a portable terminal apparatus capable of improving a usability while maintaining a security, and a use restricting method thereof. A portable terminal apparatus 1 carries out a radio authentication together with a radio communicating unit 3. The portable terminal apparatus 1 gives a predetermined alarm to a user, thereby improving a usability when a distance from the radio communicating unit is set to be an alarm distance D2 to be a shorter distance before the distance from the radio communicating unit is set to be an authentication enable distance D1.

Abstract: To provide a mobile terminal capable of switching an unlocked IC card to a lock state with optimum timing for the IC card user while preventing an unlocked IC card from being skimmed. A mobile terminal 1 according to the invention includes a use limit instruction part 131 for switching an IC card 17 between a lock state to inhibit wireless communications with a card reader/writer 2 and an unlock state to permit wireless communications with a card reader/writer 2 and a voltage detector 18 for detecting the radio wave strength of a radio wave received from the card reader/writer 2 with the IC card 17 in the unlock state, wherein the use limit instruction part 131 switches the IC card 17 to the lock state when the radio wave strength detected by the voltage detector 18 has made a transition from above a threshold to below the threshold.

Abstract: An object of the present invention is to provide an information terminal by which a user can easily perform an operation for executing a function intended by the user. An information terminal having a key operation guidance function for assisting a user to perform an operation required for execution of a function set in a mobile phone terminal 100, including a key input portion 10 having a plurality of keys capable of emitting light independently of one another, and a key operation guidance control portion 81 having a function for specifying a key the user should operate for executing the function and a function for lighting the specified key.
