<Example of cursor movement operation in information terminal in this embodiment>
An example of cursor movement operation in the information terminal 1c in the present embodiment will be described with reference to FIG. Here, the cursor 300 is displayed on the Web screen displayed on the display screen 3c of the information terminal 1c, and an operation example for moving the cursor 300 will be introduced. The information terminal 1c includes a microphone 18L and a microphone 18R in the vicinity of opposite left and right sides of the lower part of the housing. The user moves the cursor 300 in the efgh direction by performing a tapping operation around the top, bottom, left, and right EFGHs in the information terminal 1c. The determination unit 102 of the information terminal 1c determines which part of the EFGH on the bezel 5 the user has tapped based on the volume difference between the left and right sounds detected by the microphone 18L and the microphone 18R. For example, when the determination unit 102 determines that the user has tapped the position F, the cursor 300 is moved in the arrow f direction. In this case, the determination unit 102 determines that the position of F has been tapped based on the volume difference due to the volume of the sound detected by the microphone 18R being large and the volume of the sound detected by the microphone 18L being small. For example, when the determination unit 102 determines that the user has tapped the position E, the cursor 300 is moved in the direction of the arrow e. In this case, the determination unit 102 determines that the position of E has been tapped based on the volume difference due to the volume of the sound detected by the microphone 18R being small and the volume of the sound detected by the microphone 18L being large. Further, for example, when the determination unit 102 determines that the user has tapped the position H, the cursor 300 is moved in the direction of the arrow h. In this case, although there is no volume difference between the sounds detected by the microphone 18R and the microphone 18L, the determination unit 102 determines that the position of H has been tapped because both the volumes are large. Further, for example, when the determination unit 102 determines that the user has tapped the position of G, the cursor 300 is moved in the arrow g direction. In this case, although there is no volume difference between the sounds detected by the microphone 18R and the microphone 18L, the determination unit 102 determines that the position of G has been tapped because both the volumes are small. Note that the cursor 300 can be moved stepwise in accordance with the number of detection sounds detected as a tapping sound, the generation interval, and the like.
