detailed description

As shown in FIG. 1 to FIG. 3 , a handheld crystal interactive device 100 according to an embodiment of the present invention includes a controller 20 and a pressure-sensitive ball 40 connected to the controller 20 .

Further, the pressure-sensitive ball 40 in this embodiment includes: an air pressure cavity 42 and a placement cavity 44 which are arranged separately.

The air pressure cavity 42 in this embodiment is an elastic cavity that is deformed by force to change the pressure in the cavity. Preferably, the air pressure chamber in this embodiment is made of elastic rubber material.

Further, the air pressure chamber 42 of this embodiment is provided with an air pressure sensor 46 which detects the air pressure change of the air pressure chamber 42 to identify whether to hold the pressure-sensitive ball or the strength of the ball, and is connected in communication with the data processing unit.

The placement cavity 44 in this embodiment is a rigid cavity. The placement cavity 44 in this embodiment is provided with a micro-electromechanical system and a data processing unit that communicates with the micro-electromechanical system and transmits the received and processed data to the controller.

Further, the ball body of the pressure-sensitive ball 40 in this embodiment is further provided with a lock control switch 48 that is connected in communication with the controller 20 and locked by mapping to lock the position in the virtual crystal. The lock control switch 48 is in the long-closed state by default, and is in the long-open state after receiving the press for more than the set time to control the position in the crystal to be locked. If it is pressed again for more than the set time, it returns to the long-close state. If the set lock time is not reached, the control will perform a quick click command operation.

The micro-electromechanical system includes: a six-axis inertial sensor that detects the linear displacement and rotation angle of the pressure-sensitive ball. The six-axis inertial sensor of the micro-electromechanical system (MEMS) is mainly composed of three-axis acceleration sensors and three-axis gyroscopes. It can precisely respond to physical movements including linear displacement and angular rotation, and convert this response into electrical signals, which are amplified and processed by electronic circuits. When the user moves the pressure-sensitive ball, the sensor will feedback the movement direction, displacement and rotation angle to the controller in real time.

Further, the pressure-sensitive ball 40 of this embodiment is connected to the controller 20 through a fixing band 60 and a communication line is built in the fixing band for communication.

The controller 20 in this embodiment is provided with a first communication module that is communicatively connected to the pressure-sensitive ball 40 . Preferably, the first communication module in this embodiment adopts a USB module.

Further, the controller 20 of this embodiment further includes: a main control unit, a memory connected to the main control unit, a power supply module for supplying power, and a main control unit connected and controlled to communicate with an external device to upload data the second communication module. Preferably, the second communication module adopts a Bluetooth module to wirelessly communicate with the outside world or external devices. The power module can be implemented with batteries.

The controller 20 transmits the data signal of the pressure-sensitive ball 40 to the interactive software system through the Bluetooth module in real time. At the same time, the memory will store the data of the pressure-sensitive ball 40 for R&D and debugging.

The handheld crystal interaction device 100 according to an embodiment of the present invention includes: a first crystal interaction device and a second interaction device. It can be controlled by left and right hands respectively.

Each hand-held crystal interactive device is composed of a controller 20 and a pressure-sensitive ball 40 respectively. A fixing belt 60 is connected between the controller 20 and the pressure-sensitive ball 40 . In the fixing belt 60, there is a system for connecting the pressure-sensitive ball 40 and the controller 20 with a communication line based on the USB protocol. Right-handed devices are identical in appearance to left-handed devices. The first crystal interaction device and the second interaction device are only for the purpose of distinguishing and not limiting. The first crystal interaction device can be operated by either the left hand or the right hand. The second crystal interaction device can be operated by either the left hand or the right hand.

The pressure-sensitive ball 40 in this embodiment is made of elastic rubber material, and the inner cavity of the ball is divided into two parts, one is the air pressure cavity 42 and the other is the placement cavity 44 . The air pressure cavity 42 is a cavity filled with air. When the user holds the interactive ball with different strengths, the pressure in the air pressure cavity 42 will be changed. There is an air pressure sensor 46 on the inner wall of the air pressure chamber 42. When the pressure in the air pressure chamber 42 changes, the air pressure sensor 46 will acquire the data of the air pressure change in real time, so as to recognize whether the user is holding the pressure-sensitive ball 40, and sense whether the user is holding the ball. actual strength.

The placement cavity 44 is a rigid cavity that does not deform when the user grips the ball. The placement cavity 44 houses a microelectromechanical system and a data processing unit such as a data processing chip. The air pressure sensor 46 is also wired to the data processing unit. The data processing unit sends the data of each sensor to the controller 20 through the USB protocol.

The pressure-sensitive ball 40 has a built-in six-axis inertial sensor of a micro-electromechanical system (MEMS). The six-axis inertial sensor is mainly composed of three-axis acceleration sensors and three-axis gyroscopes. MEMS inertial sensors can precisely respond to physical movements, including linear displacement and angular rotation, and convert this response into electrical signals that are amplified and processed by electronic circuits. When the user moves the pressure-sensitive ball 40, the six-axis inertial sensor will feedback the moving direction, displacement and rotation angle to the controller 20 in real time.

The lock control switch 48 on the pressure-sensitive ball 40 supports three states: long-close, long-open, and hold. The lock control switch 48 is in the long-off state by default. The user presses the lock control switch 48 for more than a set time, such as more than 0.7 seconds, and releases it, so that the lock control switch 48 is in a long-open state. If it is pressed again for more than the set time, such as After 0.7 seconds and release, the lock control switch 48 returns to the long-off state. In any state, the user can keep the lock control switch 48 in the hold state by continuously pressing and holding it. If the lock control switch 48 is released at this time, the lock control switch 48 will return to the previous state. The lock control switch 48 also supports a quick click operation. Press the lock control switch 48 quickly and release it. If the duration of pressing the lock control switch 48 does not reach the set time, if the duration is less than 0.7 seconds, the state of the lock control switch 48 will not change. At the same time, a signal of a quick click operation is sent to the controller 20 .

Each pressure-sensitive sphere 40 can be mapped and locked to every atom in the crystal (only one of them can be mapped and locked at a time). It is also possible to map locked to the vertices of the unit cell. When the user wears the interactive ball with both hands, he can lock to two atoms or vertices by mapping, and then interact with the virtual crystal in real time by rotating and changing the position of the interactive ball.

When the user holds the pressure-sensitive ball 40, the air pressure in the ball will change, and the more force is applied, the greater the air pressure in the ball. The pressure sensitive ball 40 senses the degree of air pressure change by means of an internal air pressure sensor 46 .

The air pressure sensor 46 uses MEMS technology to process a vacuum chamber and a Wheatstone bridge on a single crystal silicon wafer. The output voltage across the arms of the Wheatstone bridge is proportional to the applied pressure, and has a volume after temperature compensation and calibration. Small, high precision, fast response, not affected by temperature changes. The output mode can be analog voltage output and digital signal output.

Before use, let the pressure-sensitive ball 40 stand still to calibrate the standard air pressure when the ball is not held. When the user grips the ball with different strengths, the air pressure sensor 46 converts the real-time air pressure into an electrical signal, and the system obtains the relative strength change of the ball by judging the change between the current air pressure and the standard air pressure.

Detecting whether the pressure-sensitive ball 40 is held and the strength of holding the ball are used to prevent misoperations when not in use. For example, when the pressure-sensitive ball 40 is turned on and placed on a table, the rolling of the ball may cause misoperation. After adding the ball grip and ball grip strength detection, a strength threshold can be set. When the detected strength (air pressure) is lower than this threshold, the movement or rotation of the pressure-sensitive ball 40 will not work. This avoids the problem of misoperation. Because different users have different grip strengths, users can adjust this threshold in the system to suit different usage situations.

A crystal interaction system according to an embodiment of the present invention includes:

Detection module: detects whether the first pressure-sensitive ball or the second pressure-sensitive ball is moving, detects the position of the first pressure-sensitive ball or the second pressure-sensitive ball, and performs mapping according to the position of the first pressure-sensitive ball or the second pressure-sensitive ball.

At this time, the current spatial position and posture of the pressure-sensitive ball 40 will be mapped to the vertices of the corresponding atoms or unit cells, and the user can directly change the position and posture of the vertices of the corresponding atoms or unit cells by moving or rotating the pressure-sensitive ball 40 . Since the atoms in the molecule are constrained by physical and chemical principles, the distance and angle between some atoms will remain unchanged, so when an atom is moved or rotated through the pressure-sensitive ball 40, other atoms in the molecule where this atom is located will follow the physical Move or rotate in accordance with the principles of chemistry.

If unlocking is desired, the user can release the lock control switch 48 and moving or rotating the interactive ball will have no effect on atoms or vertices within the crystal.

The switching between the locked state and the unlocked state is realized by the locking control switch 48 on the pressure sensitive ball 40 .
