Received Signal Strength In
(dicator: RSSI) 40 is provided, and the electric field strength of the received signal is detected by the RSSI 40, sent to the main body control unit 13, subjected to A / D conversion, and used for control processing.

In this display input device, first, a transmission signal generated based on the operation of the operation unit 3 of the controller 1 is:
Not only is it received by the device main body 2, the waveform is shaped by the comparator 41 and given to the main body control unit 13,
The reception intensity of the transmission radio wave given from the controller 1 to the device main body 2 is detected by the RSSI 40 and the main body control unit 1
3 given. Thereby, information on a change in the distance between the controller 1 and the device main body 2 can be provided to the main body control unit 13.

The main body control section 13 changes the operation signal based on the operation on the operation section 3 given from the comparator 41 and the change in the detection signal of the signal strength detected by the RSSI 40 (that is, the distance between the controller 1 and the apparatus main body 2). ) Can be reflected in the execution of the game program.

As a result, the following display control is performed. 4A, 4B, and 4C show examples of display contents on the display screen 5. FIG.

As shown in FIG. 4A, the main body control unit 13
Based on the execution of the game program, the display size of the movement target A of the predetermined character can be changed and the display control for moving the movement target A can be performed.

In FIG. 4A, when the signal intensity detected by the RSSI 40 is low, the operation target A is displayed large, and when the signal intensity is high, the operation target A is displayed small. As a result, when the player holding the controller 1 approaches the device main body 2 and the display unit 4, the operation target A becomes smaller, and the operation target A is moved to the rear of the display screen 5 in accordance with the movement of the player. You can get the vision to move in the direction. In addition, the player operates the main body and the display unit 4.
When the user moves away from the screen, it is possible to obtain a visual sense that the operation target A moves toward the near side of the display screen 5.

Further, based on the signal strength detected by the RSSI 40, the size of the operation target A may be changed and its position may be moved as shown by (i).
That is, when the player holding the controller 1 approaches the device body 2, the operation target A becomes smaller and (i)
The display can be controlled so as to move diagonally upward as shown by.

In the display control shown in FIG. 4B, the operation target A moves in the direction shown in (i) or (ii) in accordance with a change in the distance between the player holding the controller 1 and the device main body 2. A display that moves in the indicated direction is performed. Alternatively, the moving speed in each direction may change according to a change in the distance between the controller 1 and the device main body 2.

In the display control shown in FIG. 4C, the position of the operation target A does not move or does not move much, and the display of the background B moves in the direction shown by (iii). For example, when the player holding the controller 1 approaches the device main body 2 and the display unit 4, the background B moves in the direction of the arrow (iii), and a display feel is obtained such that the operation target A moves in the depth direction of the screen. Can be.

4A, 4B, and 4C, when the player moves while holding the controller 1 and operates the operation unit 3, the operation target A itself moves or changes direction. And the like.

Here, for example, when the display control shown in FIG. 4A is performed, the player holding the controller 1 places the operation target A on the display screen 5 at a predetermined distance from the display unit 4. At that time, the player performs a setting operation using the operation unit 3, and the player approaches the display unit 4 by a predetermined distance, and at that time, the operation target A is reduced to a predetermined size. Display is performed, and a setting operation is performed using the operation unit 3 at that time.

After the setting, when the player moves between the set positions, display control is performed such that the size of the operation target A changes in proportion to the amount of movement from the set position.

Alternatively, when the game program is a shooting game, the accuracy of hitting the target may be changed according to a change in the distance between the controller 1 and the device main body 2. That is, when the player having the controller 1 is separated from the device main body 2, control can be performed such that accuracy of hitting the target is reduced.

In the display control device having the circuit block diagram shown in FIG. 3, a transmission signal (operation signal) corresponding to the operation of the operation section 3 is given from the controller 1 to the device main body 2, and the transmission signal (operation signal) is transmitted. ) Is detected. However, from controller 1,
A transmission signal (operation signal) according to the operation of the operation unit 3 and a continuous signal or an intermittent signal for distance measurement having a predetermined strength may be transmitted as different signals. In this case, both signals may be oscillated at the same time, or may be time-divisionally transmitted alternately.

In this case, the receiving unit recognizes the operation signal and the signal for distance measurement separately. According to this configuration, the signal for distance measurement can be made a weak signal to greatly change the intensity of the received signal due to a change in distance, and the operation signal can be reliably received at a predetermined intensity.

In order that the RSSI 40 can reliably detect the reception intensity of the operation signal itself or the reception intensity of the distance measurement signal, the receiving section of the controller includes a constant current and a constant current. It is preferable to provide a constant voltage circuit so that transmission with the same intensity can always be performed even when the battery is consumed.
