4. An electronic device, comprising: a display unit that displays a character input screen; a sensor that detects motion; an input unit that inputs a character to be displayed on the character input screen; and a control unit that displays, on the display unit, conversion candidates or predictive candidates for the character that has been input from the input unit, wherein, when a name of an application is displayed as an input character string on the display unit, the control unit displays names of processing in the application as predictive candidates regarding the name of the application, and when a name of processing is selected, the control unit executes the processing corresponding to the name, wherein, if there are names of functions for setting states of the electronic device as the conversion candidates or the predictive candidates, the control unit displays the names of functions along with the names or a name of processing, and when any one of the names of functions is selected, the control unit executes setting of a state of the electronic device corresponding to the selected name, wherein the control unit accepts selection of any one of the names of the processing or the names of the functions according to type of the motion detected by the sensor, wherein the control unit alternately displays the names of the processing or the names of the functions in response to the sensor detecting predetermined motion in a state where the predictive candidates are displayed, and displays the predictive candidates in response to the sensor detecting predetermined motion in a state where the names of the processing or the names of the functions are displayed, the names of the processing and the names of the functions representing activity candidates, in response to selection of one of which the control unit executes processing corresponding to the selected activity candidate, the predictive candidates representing at least one character, in response to selection of which the control unit adds the at least one character to the character input screen.
4. An electronic device, comprising: a display unit that displays a character input screen; a sensor that detects motion; an input unit that inputs a character to be displayed on the character input screen; and a control unit that displays, on the display unit, conversion candidates or predictive candidates for the character that has been input from the input unit, wherein, when a name of an application is displayed as an input character string on the display unit, the control unit displays names of processing in the application as predictive candidates regarding the name of the application, and when a name of processing is selected, the control unit executes the processing corresponding to the name, wherein, if there are names of functions for setting states of the electronic device as the conversion candidates or the predictive candidates, the control unit displays the names of functions along with the names or a name of processing, and when any one of the names of functions is selected, the control unit executes setting of a state of the electronic device corresponding to the selected name, wherein the control unit accepts selection of any one of the names of the processing or the names of the functions according to type of the motion detected by the sensor, wherein the control unit alternately displays the names of the processing or the names of the functions in response to the sensor detecting predetermined motion in a state where the predictive candidates are displayed, and displays the predictive candidates in response to the sensor detecting predetermined motion in a state where the names of the processing or the names of the functions are displayed, the names of the processing and the names of the functions representing activity candidates, in response to selection of one of which the control unit executes processing corresponding to the selected activity candidate, the predictive candidates representing at least one character, in response to selection of which the control unit adds the at least one character to the character input screen. 5. The electronic device according to claim 4 , wherein, when the name of the processing is selected, the control unit executes processing corresponding to the name, or executes processing of displaying the name of the processing as a character string on the display unit.
