Description

The utility model belongs to the computer technology and gaming industry and can be used for user interaction with computerized devices (computers, laptops, game consoles, smart TVs, etc.).

A well-known device for control using gestures (Patent of Ukraine 105864, IPC SObE 3/00, 5090 5/00, publ. 25.06.2014), which is a bracelet for wearing it on the wrist. The bracelet contains a housing in which a microcontroller is mounted for processing and receiving/transmitting information from sensors to a computerized device, a power source, an accelerometer, a gyroscope, and a magnetometer, which are connected to the microcontroller.

The disadvantage of the known device is its great technical complexity and inconvenience in use. Controlling a device located on the wrist is intuitively more difficult than a device fixed on the palm, where the movement of the hand fully corresponds to the movement of the controlled object. In addition, in comparison with the proposed useful model, the analogue is less compact, much simpler in terms of design and more convenient to use. In the known device, at least sets of sensors (18 sensors in total) are needed for implementation, each of which is connected to the microcontroller separately. You also need an indication unit in the form of a display (glasses), a powerful mini-computer for processing a large amount of data from sensors and for forming an image on the display, which complicates the design of the device too much, as it requires the use of a larger number of components.

The closest analogue of the useful model is the device for interaction with computer equipment "Gear Moyop" (AG: pOrz//ps.na/apisiev/or2o1-Ivear-toyop-irgamieepie-Kotrushetgot-matapot-gyKi/), in which to determine the movement two monochrome infrared cameras and three infrared emitters are used. The cameras "scan" the space above the surface of the table with a frequency of up to 300 frames per second and transmit the received data through a wired connection to a computer, where they are processed by installed software.

Management is carried out with the help of fingers.

The disadvantage of the closest analogue is its inconvenience in use due to rapid fatigue of the fingers (it is quite difficult to make micro-movements in the air with the fingers of an outstretched hand) and the low quality of the implementation of the transmission of gesture control signals from the user to the computer due to the inaccuracy of motion tracking in the Gear Moiop.

The basis of the useful model is the task of improving the device for interaction with a computerized device, in which due to the implementation of the device with a belt for attaching it to the hand of the user and the use of accelerometer, gyroscope and magnetometer sensors in the device, which are connected to a microcontroller, increases ease of use (the device is easy and quick to put on and take off), and the quality of interaction with computerized devices (PCs, laptops, game consoles, smart TVs, etc.).

The technical result, which is achieved when solving the task and using the proposed device, consists in increasing the convenience of its use and improving the quality of interaction with the controlled computerized device.

The task is solved by the fact that the proposed device for interaction with a computerized device, containing a case in which a microcontroller is mounted for processing information from sensors and receiving/transmitting information to a computerized device and a wireless and/or wired data receiving/transmitting module per computerized device, according to a useful model, includes at least one accelerometer sensor, at least one gyroscope sensor, and at least one magnetometer sensor, which are connected to the microcontroller by data buses, and a strap is attached to the housing for attaching the device to the hand user

According to the useful model, the fastening belt is made removable.

According to the utility model, the fastening belt is made of elastic material.

The implementation of the proposed device with the possibility of attaching to the hand of one of the user's hands (depends on the user's desire or capabilities) provides an increase in the convenience of his interaction with the computerized device by means of the movement of the palm, which is completely copied and reproduced by the objects of interaction on the computerized device.

The use of an accelerometer, gyroscope and magnetometer in the device allows the microcontroller, based on the data received from the mentioned sensors, to calculate the change in the position of the device body in space without mechanical attachment to any surface, without the use of mechanical parts, to increase the accuracy of its interaction with the controlled computerized device .

The fastening belt can be made removable and/or adjustable in length by making it from an elastic material, for example, a textile elastic for the convenience of its use by users with different physical parameters.

The advantage of the claimed device is also its small size (like an ordinary credit card).

The device is made with dimensions of approximately 5x8 cm, is compact, and therefore can be placed, for example, in a pocket without the risk of its damage.

The device can also combine sensors connected to a microcontroller into a separate chip, which simplifies the design of the device, as it requires the use of fewer components and connections.

The proposed useful model is explained by the following drawings.

In fig. 1 shows the front view of the device.

In fig. 2 shows the side view of the device.

In fig. C shows the rear view of the device.

In fig. 4 shows the device worn on the wrist.

In fig. 5 shows the device with an inclination relative to the X axis.

In fig. 6 shows the device with an inclination relative to the U axis.

In fig. 7 shows the device with its right turn.

The proposed useful model is made in the form of a card, contains a housing 1, to which a strap 2 of the device is attached to the hand of the user, a module for the wire reception/transmission of data to a computerized device (not shown), which is a wire 3.

The connection of the device with a computerized device can be implemented in a wireless way thanks to the use of a wireless data reception/transmission module, which can be, for example, a radio channel with a radio module or an infrared communication channel with at least one infrared sensor. To power the module of wireless reception/transmission of data in the body of the device, there is a place for an autonomous power element, which can be any known miniature power element, for example, a battery of the "tablet" type.

The module for wireless and/or wired reception/transmission of data can be equipped with an O5V port for connection with a computerized device. On the printed circuit board (no

zo is shown), which is mounted on the case or in the case 1, a gyroscope sensor, an accelerometer sensor and a magnetometer sensor are placed, which are one chip 4, and are connected by data buses to the microcontroller 5, which is necessary for processing information from the sensors and receiving/transmitting information to a computerized device.

At the same time, in the declared utility model, it is possible to use several accelerometer sensors, gyroscope sensors and magnetometer sensors, which, forming arrays of sensors, will increase the accuracy of the data transmitted to the microcontroller.

The fastening belt 2 for convenience can be made completely or partially with inserts, from an elastic material, for example, a textile elastic band.

Also, the belt can be removable and attached to the body 1, for example, with a textile fastener.

In addition, the combination of all components of the claimed device in a single housing makes it mobile, as it creates the possibility, if desired, to use it simultaneously or alternately with different control devices. The case can be made, for example, of textolite or other materials.

The proposed device is used as follows.

The user fastens the device on the hand (as shown in Fig. 4) using the strap 2 under the middle phalanx of the fingers. Next, the device is connected to a computerized device for interaction with the latter. Such a device can be, for example, a PC. As a rule, this operation takes place by adding the proposed device to the list connected to the computerized device using the capabilities of its operating system. At the same time, the connected device can be perceived by the computerized device in different ways, depending on its configuration, for example, as a joystick or any other device from a number of standard ones for the operating system, or as one that requires the installation of its own drivers. It is possible to connect the device to the computerized device both in a wired way using wire 3, and using known wireless connection methods. For this, the computerized device must be equipped with appropriate devices for wireless connection, for example, have a radio module or an infrared receiver for receiving and transmitting signals from a wireless data reception/transmission module (which can be, for example, a radio channel with a radio module or an infrared communication channel connection with at least one infrared sensor) to a computerized device. Further, the device can be used as intended as a standard control device for certain software, for example, in computer games, programs, etc.

The very process of interaction of the proposed device with a computerized device consists in the exchange of data packets via wired or wireless communication. During the operation of the device, the sensor data of chip 4 is processed (chip 4 uses sensors to measure the acceleration and angular velocity of rotation of the body 1 relative to three axes - X, M, 7 and records the absolute magnitude of the intensity of the Earth's geomagnetic field (along the X, Y, 7 axes) according to using the microcontroller 5 and sending them to the computerized device in the necessary normalized form, that is, for example, in the form of a control manipulator operation protocol instead of a standard one (computer mouse, joystick, etc.) or in another form necessary for the computerized device.

Chip 4 sensor data is processed as follows.

Microcontroller 5 periodically (x 100 times per second for the necessary positioning accuracy of the device) polls the sensors of chip 4, communication with which is carried out by implementing a digital protocol common to microcontroller 5 and chip 4, and after reading the readings of the sensors, it calculates the current inclination of the body 1 of the device relative to the horizon along the X, Y axes (angles a, B) and the angle of rotation (c) of the body relative to the Earth's magnetic field along axis 2 (compass).

Received, processed and normalized sensor indicators from the microcontroller 5 are sent through the data reception/transmission module to the computerized device, which processes the received data and implements the necessary actions depending on the settings of the declared device and the software executed on the computerized device: controls virtual objects (three-dimensional models) in space or performs any other actions provided by the software.

For example, this device can be used in computer ZO-games. With the help of the device, the user can control the game process more intuitively than when using traditional means of input, such as, for example, a computer mouse or a game joystick. For control, the user just needs to make a certain movement that will repeat the virtual controlled object.

As another example, you can consider the operation of the device as a manipulator for controlling an airplane in a computer flight simulator, where the game object is controlled by tilting/rotating the hand. Thus, when raising the palm with the device worn on the palm of the hand upwards, using the software based on the data received from the declared device, the nose of the controlled virtual model of the aircraft is raised upwards, when lowered - the nose of the aircraft will begin to descend. Likewise, the angular inclinations (turns) of the palm will correspond to the roll and turn of the controlled object. At the same time, there is no discreteness, that is, the stronger the deviation of the palm, the stronger the reaction. The main thing is that controlling the palm is much easier (on an intuitive level) than with a joystick, because the movement of the hand corresponds to the movement of the controlled object (aircraft).

The inclination of the body relative to the X axis (rotation around the Y axis, angle a) is similar to the deviation of a conventional joystick away from itself (on/-a) (Fig. 5).

The tilt of the body relative to the M axis (rotation around the X axis, angle B) is similar to the deviation of a conventional joystick to the right/left (w-B/-B) (Fig. 6).

When initializing the device (connecting it to a PC, software reinitialization), the initial value of the angle of rotation (s) (hereinafter - s) is fixed. The rotation of the housing 1 relative to axis 2 is similar to the rotation of the handle of a conventional three-axis game joystick.

The angle of rotation of the device (c") is calculated as the difference between the angles c and c, (a positive value of c" is a turn to the right, a negative value is to the left).

The corner of the "s"-o-s.

In fig. 7 shows turning the device 102 to the right.

The initial value of rotation of the housing 1 of the device is -302, the current angle of rotation is -409. M - direction to the north magnetic pole.

The number of axes of the claimed device can be increased from three to six. As additional axes, the values of the movement of the device along the X, Y, 7 axes relative to the initial position (or reinitialization point) of the device can be used.

The claimed device can be manufactured by methods known in the electronic industry using known means and can be used in computer technology, the game industry (control of the game process in computer games, simulators) for human interaction with computerized devices ( computers, laptops, game consoles, smart TVs, etc.).

This useful model provides increased accuracy of interaction with a controlled computerized device, and is more convenient to use compared to known analogues.
