technical field

The invention relates to a hand-held controller, in particular to a method for determining a rotation action signal of the hand-held controller and an electronic device thereof.

Background technique

Due to the progress of science and technology, video game consoles have entered the families of modern people. Also due to the vigorous development of the video game industry, related game software and hardware manufacturers are committed to developing the latest game software and hardware, making the game screen more realistic and the operating device more sensitive.

Basically, a video game console uses a game console to execute game software and operate with an operating device. That is to say, the user controls the operating device and generates a specific action signal to the game console. And according to the specific action signal, the game console can control the picture of the game software in the display screen. Generally speaking, most of the operating devices are operated by the user's hands, so they can also be called handheld controllers.

Please refer to FIG. 1 , which shows an existing handheld controller and its game console. Generally speaking, the existing handheld controller 10 has a transmission line 12 connected to the game console 30 . The handheld controller 10 has a cross key 14 and a plurality of action keys 15 , 16 , 17 , 18 , 19 , 20 . The cross key 14 can be operated by the user to output forward, backward, left, and right direction signals, and the action keys 15-20 can be used by the user for specific actions, such as shooting actions, jumping actions, selection actions, input actions, etc. . The game host 30 also includes a processing unit 32 for receiving all signals output by the handheld controller 10 , and the processing unit 32 can judge the signals output by the handheld controller 10 to control the screen of the game software.

Please refer to FIG. 2, which shows another existing handheld controller and its game console. In order to facilitate the user's control, a hand-held controller 50 transmitted by Bluetooth has been released. The generated signal is transmitted to the game console by wireless transmission. Furthermore, the handheld controller 50 has a movable space 56 for placing a joystick 54 to replace the cross key to output direction signals, so that the joystick can generate more different direction signals. When the user controls the direction, he only needs to use his thumb to press the upper position of the joystick 54 to control the direction, and then the direction signal can be generated. Similarly, the game console 60 also includes a wireless signal receiving unit 62 and a processing unit 64, the wireless signal receiving unit 62 can receive all the signals output by the wireless signal transmitting unit 52 in the handheld controller 50 and transmit them to the processing unit 64, And the processing unit 64 can judge the signal output by the hand-held controller and control the screen of the game software to proceed.

However, although the handheld controller 50 can be applied to most game software. However, there are still a small number of game software that cannot operate with the signal of the handheld device 50, such as dancing game software. For this kind of game software, the manufacturer must design a stepping device to match with the dancing game software. That is to say, for game software with specific actions, manufacturers must design specific operating devices to match each other, but such operating devices are expensive and have low usage rates.

Detailed ways

For game software with specific actions, manufacturers must design specific operating devices to match each other. The present invention determines a specific action by analyzing the signal output by the hand-held controller and applies it to the game software.

Taking the handheld controller in Figure 2 as an example, the handheld controller cannot simulate the actions of the fishing game software. For example, the user can use the up and down motion of the arm to simulate the motion of swinging the fishing rod. However, the action of setting out and taking up the line in the fishing game software cannot be completed by the hand-held controller.

That is to say, when the handheld controller is swiped up and down, an inertial sensor in the handheld controller can sense the movement pattern of the operator and output a corresponding strength signal. However, since there is no rotating mechanism in the handheld controller, the handheld controller in FIG. 2 is not suitable for fishing game software. That is to say, the manufacturer must design a specific operating device to generate the wire-releasing and winding-up action signals.

According to an embodiment of the present invention, in order to be able to apply the handheld controller in FIG. 2 to fishing game software, the present invention uses a fast clockwise or counterclockwise direction to operate the joystick on the handheld controller, so that the game instrument ( or an electronic device) the processing unit in the host can continuously receive direction signals of a specific sequence, and determine that the user is performing a wire-releasing action or a wire-receiving action according to the direction signals of a specific sequence.

Please refer to FIG. 3 , which is a schematic view showing the action of the handheld controller and its game console during rotation. When the fishing game software is executed, the user can place a hand on the joystick 154 and operate the joystick 154 clockwise or counterclockwise. Since the joystick is operating in a specific order, the handheld controller 150 will continuously output direction signals in different directions to the wireless signal receiving unit 162 of the game console 160 and then transmit them to the processing unit 164 . The processing unit 164 can determine whether the user is performing a wire-releasing action or a wire-receiving action according to direction signals of different directions.

Generally speaking, the joystick 154 of the handheld controller 150 is a 2dimensional analog joystick, and the joystick can simultaneously output an X-axis value and a Y-axis value. A direction signal can be generated according to the X-axis value and the Y-axis value. For example, the X-axis value of this kind of joystick varies from -1V to +1V, and the Y-axis value varies from -1V to +1V.

When the X-axis value output by the joystick is +0.5V and the Y-axis value is +0.5V, the direction signal is the 45-degree direction of the first quadrant, as shown in FIG. 4A . Similarly, when the X-axis value output by the joystick is -0.5V and the Y-axis value is +0.5V, the direction signal is the 135-degree direction of the second quadrant, as shown in Figure 4B; when the X-axis value output by the joystick When the value is -0.5V and the Y-axis value is -0.5V, the direction signal is the 225-degree direction of the third quadrant, as shown in Figure 4C; and, when the X-axis value output by the joystick is +0.5V and the Y-axis When the value is -0.5V, the direction signal is the 315-degree direction of the fourth quadrant, as shown in Figure 4D. That is to say, the processing unit determines the direction signal according to the X-axis value and the Y-axis value.

Please refer to FIG. 5A , which shows the change of X-axis and Y-axis values generated by controlling the joystick in a clockwise direction. When the joystick is operated in a clockwise direction and starts from the direction of the positive X-axis, the value of the X-axis changes from +1V to 0V to -1V to 0V, showing a sinusoidal change; while the value of the Y-axis changes from 0V to -1V to 0V to +1V presents a sine wave change. It can be seen from FIG. 5A that the phase of the sine wave of the value on the Y axis is ahead of the sine wave of the value on the X axis by 90 degrees, which means clockwise operation. Therefore, the processing unit continuously receives the sampled values of the X-axis and the Y-axis, and determines that the angles of the different direction signals are continuously decreasing, so that it can be known that the user operates the joystick in a clockwise direction. The higher the frequency of the sine wave, the faster the user's rotation in the clockwise direction.

Please refer to FIG. 5B , which shows the change of X-axis and Y-axis values generated by controlling the joystick counterclockwise. When the joystick is operated in the counterclockwise direction and starts from the positive X-axis direction, the X-axis value changes from +1V to 0V to -1V to 0V, showing a sine wave change; and the Y-axis value changes from 0V to +1V to 0V to -1V presents a sinusoidal change. It can be seen from FIG. 5B that the phase of the sine wave of the value on the X axis is 90 degrees ahead of the sine wave of the value on the Y axis by 90 degrees, that is, the operation is in the counterclockwise direction. Therefore, the processing unit continuously receives the sampled values of the X-axis and the Y-axis, and determines that the angles of the different direction signals increase continuously, so that it can be known that the user operates the joystick counterclockwise. The higher the frequency of the sine wave, the faster the user's rotation in the counterclockwise direction.

Alternatively, as shown in FIGS. 6A and 6B , by continuously sampling the X-axis value and the Y-axis value, it can be analyzed that the user is performing a rotation action according to the sampled X-axis value and the sampled Y-axis value. For example, when the processing unit receives the sampled X-axis value of 1 and the sampled Y-axis value of 0 at time point 1; the sampled X-axis value of 0 and the sampled Y-axis value of -1 at time point 2; At point 3, the sampled X-axis value is -1 and the sampled Y-axis value is 0; at time point 4, the sampled X-axis value is 0 and the sampled Y-axis value is 1; after time point 5, the sampled X-axis value is the same as When the sampled Y-axis value continues to change periodically according to the above-mentioned value, it can be determined that the user operates the joystick clockwise. Similarly, when the processing unit receives the sampled X-axis value of 1 and the sampled Y-axis value of 0 at time point 1; the sampled X-axis value of 0 and the sampled Y-axis value of 1 at time point 2; The sampled X-axis value is -1 and the sampled Y-axis value is 0; the sampled X-axis value is 0 and the sampled Y-axis value is -1 at time point 4; and the sampled X-axis value is the same as the sampled value after time point 5 When the Y-axis value continues to change periodically according to the above-mentioned value, it can be determined that the user operates the joystick counterclockwise.

According to the embodiment of the present invention, the processing unit is used to analyze the change of the direction signal output by the joystick on the existing hand-held controller, that is, it can be judged whether the user is performing the rotation action and the direction of the rotation. Furthermore, since the joystick 154 is located in the handheld control 150 a movable space 156 .

As shown in FIG. 7 , according to an embodiment of the present invention, the side of the movable space 156 can be designed as a polygon (such as a regular octagon), so that the joystick 154 will bump into the side of the movable space 156 when it is rotated rapidly. Make a noise. The faster the rotation, the faster the sound. That is to say, the sound is similar to the sound when setting out or taking up the line during actual fishing, which makes the user feel more present when playing the fishing game software.

Of course, the present invention only uses the fishing game software as an example. Other game software, such as kite-flying game software, may use the present invention to analyze the change of the direction signal output by the joystick on the handheld controller. achieved.

In summary, although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention, and any person skilled in the art may make various modifications without departing from the spirit and scope of the present invention. and modification, so the protection scope of the present invention should be determined by the scope defined by the appended claims.
