  Hereinafter, a mobile phone will be described as an example of the mobile terminal device. The present invention can be applied not only to a mobile phone but also to a portable PDA (Personal Data Assistance, Personal Digital Assistants), a game machine, and the like.

  As shown in FIG. 2, the mobile phone 11 of the present embodiment includes a CPU (Central Processing Unit) 12, a ROM (Read Only Memory) 14, a work memory 15, a voice discrimination memory 16, a microphone 17, and a voice control unit 18. A temperature sensor 20, a temperature sensor control unit 19, a display unit 22, a display control unit 21, and a transmission / reception unit 23. The unit 18 is connected to the temperature sensor control unit 19, the display control unit 21, and the transmission / reception unit 23.

  The ROM 14 stores various control programs executed by the CPU 12 and various data used in processing.

  For example, a RAM (Random Access Memory) is used as the work memory 15 and temporarily stores data necessary for the CPU 12 to execute processing according to the control program.

  The CPU 12 executes various processes in accordance with the control program stored in the ROM 14, thereby realizing a function as a well-known mobile phone 11 that enables transmission and reception of telephone calls, e-mails, and information using a communication network. In addition, the operation method of the present invention to be described later is realized.

  The voice control unit 18 performs a known voice recognition process on the voice input from the microphone 17 and discriminates the words input as the voice. The speech recognition processing is described in, for example, Japanese Patent Application Laid-Open No. 2002-165285, Japanese Patent Application Laid-Open No. 2003-195891, Japanese Patent Application Laid-Open No. 2007-171537, and the like.

  The voice discrimination memory 16 is a memory in which various words inputted by voice through the microphone 17 are recorded as a database. The CPU 12 collates the words discriminated by the voice control unit 18 with the words stored as a database in the voice discrimination memory 16, and when the words discriminated by the voice control unit 18 are registered in the database, the database Based on the above, the meaning of the words determined by the voice control unit 18 is determined. Such processing by the microphone 17, the voice control unit 18, and the CPU 12 realizes an operation unit for operating the mobile phone 11. For example, a non-volatile memory is used as the voice discrimination memory 16. The processing unit 1 shown in FIG. 1 is realized by the CPU 12, the ROM 14, the work memory 15, the voice discrimination memory 16, the microphone 17 and the voice control unit 18 shown in FIG.

  The temperature sensor 20 is a sensor for measuring the ambient temperature of the mobile phone 11. The temperature sensor control unit 19 converts the output value of the temperature sensor 20 into temperature information and transmits it to the CPU 12. The temperature detection unit 2 for detecting the ambient temperature of the mobile phone 11 shown in FIG. 1 is realized by the temperature sensor 20 and the temperature sensor control unit 19 shown in FIG.

  The display control unit 21 is a control circuit for causing the display unit 22 to display images, characters, and the like according to instructions from the CPU 12. The display unit 22 is a display device such as a liquid crystal panel or an organic EL (electrofluorescence) panel, and is disposed on the front surface of the mobile phone 11 main body (not shown), for example.

  The transmission / reception unit 23 is a circuit for transmitting and receiving voice and data to and from the radio base station by enabling radio communication with a radio base station (not shown). The transmission / reception unit 23 can be realized by a wireless communication unit provided in a known mobile phone.

  FIG. 3 is a flowchart showing an example of a method for operating the portable terminal device of the present invention.

  The processing of the mobile terminal device (mobile phone 11) of the present invention described below is realized by the CPU 12 shown in FIG. 2 executing processing according to a control program stored in the ROM 14.

  For example, when an incoming call or e-mail is received from the mobile phone 11 or when the user performs an operation such as opening or closing the lid of the mobile terminal device (step S61), the CPU 12 causes the temperature sensor control unit 19 to The measured value of the sensor 20 is acquired, and the measured value is converted into temperature information and transmitted (step S62). The opening / closing of the lid of the portable terminal device can be detected by providing the portable terminal device with a switch that is turned on / off by opening / closing the lid, for example.

  Next, the CPU 12 determines whether or not the temperature (ambient temperature) transmitted from the temperature sensor control unit 19 is equal to or lower than a preset threshold value (step S63).

  When the ambient temperature is higher than a preset threshold value, the CPU 12 maintains a state in which an input operation using a normal operation button is possible (hereinafter referred to as a normal input mode). In this case, the user starts a call or transmission / reception of an e-mail by a normal operation using the operation button (step S72).

  When the ambient temperature is equal to or lower than a preset threshold value, the CPU 12 turns on the microphone 17 by the voice control unit 18 (step S64), and allows a voice input operation (hereinafter referred to as voice input mode). (Step S65). Further, the display control unit 21 displays on the display unit 22 that voice input is possible and notifies the user (step S66).

  When the user speaks into the microphone 17, a well-known voice recognition process is executed by the voice control unit 18, and words based on the user's voice acquired through the microphone 17 are determined (step S 67). The words determined by the voice control unit 18 are notified to the CPU 12.

  The CPU 12 collates the words uttered by the user determined by the voice control unit 18 with the words stored in advance as a database in the voice determination memory 16 (step S68), and is determined by the voice control unit 18. It is determined whether or not the word matches the word stored in the database (step S69).

  When the words discriminated by the voice control unit 18 match the words stored in the database, the CPU 12 discriminates the contents of the matching words based on the database and executes the operation specified by the words ( Step S70). The operations to be executed include, for example, transition to a call state, reference of received email, creation of email, transmission of created email, and the like.

  On the other hand, when the words discriminated by the voice control unit 18 do not match the words stored in the database, the CPU 12 displays on the display unit 22 that the voice recognition has failed and notifies the user (step S71). ). Then, it returns to the process of step S66 and repeats the process of step S66-step S69.

  In the above description, an example is shown in which the ambient temperature of the mobile phone 11 is actually measured using the temperature sensor 20, but the ambient temperature can also be obtained using other means. For example, information on the current position of the mobile phone 11 may be acquired, and the voice input mode may be validated when the current position is in a cold region where the temperature is lower than a predetermined temperature. As a means for acquiring the current position, there is a GPS (Global Positioning System). In the case of the mobile phone 11, the position of the communicable radio base station may be used as the position information of the own device.

  If the mobile phone 11 includes an altitude sensor (such as an atmospheric pressure sensor) that measures the altitude, the altitude sensor measures the current altitude of the mobile phone 11 and an altitude (predetermined) that is equal to or higher than a preset threshold value. The voice input mode may be enabled at an altitude that is equal to or lower than the temperature of

  Further, when the mobile phone 11 has calendar information, the current season and date are determined from the calendar information. For example, the voice input mode is set in the season (winter) or date when the average temperature is equal to or lower than a predetermined temperature. It may be enabled.

  Means for acquiring the position information, altitude information, calendar information, and the like are also included in the temperature detection unit 2 included in the mobile terminal device of the present invention. The temperature detection unit 2 may be a combination of means for acquiring position information, altitude information, calendar information, and a temperature sensor.

  In the above description, an example is shown in which temperature measurement is started when an incoming call or e-mail is received from the mobile phone 11 or when the user performs an operation such as opening or closing the lid of the mobile terminal device. The portable terminal device of the invention can be set in the temperature measurement mode in advance using a predetermined operation button or the like. In that case, even if there is no incoming call or e-mail, if the ambient temperature is above the threshold, the normal input mode is switched to the voice input mode, and if the ambient temperature is higher than the threshold, voice input is performed. Switch from mode to normal input mode. For example, even if it is in a cold region, when the mobile terminal device is put in a pocket or the like, the ambient temperature becomes relatively high, so it is in the normal input mode. When it shifts and puts it in the pocket again, it switches to the normal input mode.

  In the above description, an example is shown in which the mobile phone 11 shifts to the voice input mode when the ambient temperature of the mobile phone 11 is equal to or lower than the threshold value, but the mobile phone 11 may be directly switched to a preset operation mode. For example, when the ambient temperature of the mobile phone 11 is below the threshold and the user shakes the main body of the mobile phone 11 and detects an acceleration that is greater than or equal to a predetermined threshold, an operation for shifting to a call state (off-hook) Can be considered. The acceleration can be detected by using a known acceleration sensor.

  Further, when the ambient temperature of the mobile phone 11 is equal to or lower than the threshold value, the call volume may be shifted to a hands-free call state by increasing the reception volume output from a speaker (not shown).

  Furthermore, the threshold value need not be one, and a plurality of threshold values may be set. For example, when the ambient temperature of the mobile phone 11 is equal to or lower than a first threshold value, the voice input mode is entered, and the ambient temperature of the mobile phone 11 is equal to or lower than a second threshold value lower than the first threshold value In some cases, the call volume may be shifted to a hands-free call state by increasing the volume of received sound output from a speaker (not shown).

  The threshold value need not be set on the low temperature side, and may be set on the high temperature side. For example, when the ambient temperature of the mobile phone 11 is equal to or higher than the threshold set on the high temperature side, it is considered that the screen is bright by being exposed to direct sunlight. What is necessary is just to make it easy to visually recognize.

  According to the present invention, when the ambient temperature of the mobile phone 11 is equal to or lower than a preset threshold value, or when the mobile phone 11 is considered to be in a low temperature environment from position information, altitude, calendar information, etc., the operation button The mobile phone 11 can be operated by voice input without pressing the button or the like. Accordingly, the portable terminal device can be easily operated even when wearing a cold protection device such as a glove or when the hand feeling is paralyzed due to cold. Therefore, a portable terminal device can be obtained in which the optimum operation means is selected according to the ambient temperature.
