( Configuration of add-on devices)

Hereinafter, the add-on device 200 providing the indirect haptic feedback of the present invention will be described. First, FIG. 1 illustrates a perspective view in which an add-on device 200 providing an indirect haptic feedback of the present invention is rigidly coupled to a notebook. As shown in FIG. 1, the USB connector 210 of the add-on device 200 is coupled to a USB port of a notebook, which is one of the host PCs 100 commonly used by a user. Therefore, the add-on device 200 and the host PC 100 are rigidly coupled, and the vibration of the haptic feedback module 230 occurs in the add-on device 200, so that the rigid-coupled host PC 100 also vibrates to the host PC. Indirect haptic feedback is provided to the user who uses 100.

The host PC 100 used in the present invention is provided with a plurality of groove-shaped connector connectors 120, preferably in a position close to the connector connector in the form of a notebook, netbook, smartphone, mobile phone, etc. corresponding to the small It is limited to that provided with an application means such as a keyboard, a keypad. Rigid coupling is typically provided with a connector 210 of the add-on device 200 in the shape of a protrusion, the connector connection portion 120 of the host PC 100 is provided in a groove shape is the connector 210 and the connector connection portion 120 It becomes possible by shape-fitting. The technical idea of the present invention is that the add-on device 200 and the host PC 100 are coupled to each other by fitting the connector 210 and the connector connection part 120 to each other, and thus the length and width of the connector 210 for rigid coupling. Changes in the length and width of the connector connection portion 120, etc. are all within the scope of the present invention within the scope that can be easily determined by those skilled in the art.
The rigid coupling of the specification of the present invention means that the vibration of the add-on device 200 by the haptic feedback module provided in the add-on device 200, which will be described later, is located in the vicinity of the connector connection portion 120 of the host PC 100. It means that the user in contact with the application means is coupled to the extent that vibration is felt. The proximate part represented in the specification means an area within a distance where the user can feel the indirect haptic feedback by the vibration of the add-on device 200.
Such rigid coupling is possible by tightly fitting the connector 210 of the add-on device 200 and the connector connection part 120 of the host PC 100. In addition, the indirect feedback system of the present invention may further include a separate coupling means for rigidly coupling the add-on device 200 and the host PC (100). For example, the coupling means may include an insertion member having a plurality of protrusions additionally formed at a portion where the connector 210 of the add-on device 200 is positioned to be coupled to each of a plurality of grooves separately provided in the host PC. It may be provided. Such coupling means may be provided by various means that can increase the coupling force between the add-on device 200 and the host PC within a range that can be clearly determined by those skilled in the art.

2 illustrates a block diagram of the add-on device 200 rigidly coupled to the host PC 100. As shown in FIG. 2, the host PC 100 includes a connector connection part 120. In addition, the add-on device 200 is provided with a connector 210 that is firmly coupled to and detachable from the connector connection unit 120. When the add-on device 200 is rigidly coupled to the host PC 100, the add-on device 200 includes electrical circuit means 220 for electrically connecting the host PC 100 and the add-on device 200.

The electric circuit unit 220 receives the input signal of the host PC 100 through the connector 210 when the add-on device 200 is coupled to the host PC 100, and receives the electrical signal of the input signal from the haptic feedback module 230. ). The haptic feedback module 230 receives the electrical signal to form tactile information. That is, three-dimensional movement is generated. Therefore, the add-on device 200 moves together with the vibration of the haptic feedback module 230, and the host PC 100 rigidly coupled with the add-on device 200 also vibrates to provide indirect haptic feedback to the host PC user. Will be provided. Vibrating the host PC 100 does not vibrate the entire small host PC 100, but generates a fine vibration in a position close to the portion where the add-on device 200 is coupled, so that the add-on device 200 This means that the haptic feedback can be delivered to the user who has touched the keyboard or the like provided at a position close to the coupled portion. The proximate portion refers to an area within a distance where the user can feel the indirect haptic feedback by the vibration of the add-on device 200.

Since the haptic feedback module 230 is a three-dimensional movement by receiving an electrical signal, the add-on device 200 may also be any type as long as it moves. However, the hip-hop feedback module 230 is an add-on device 200 is coupled to the host PC 100, the keyboard, touch pad, etc. are provided in a position close to the portion of the host PC 100 to which the add-on device 200 is coupled. You should be able to feel the haptic feedback to the contacted user. The proximate portion refers to an area within a distance where the user can feel the indirect haptic feedback by the vibration of the add-on device 200. A feature of the present invention is that the add-on device 200 and the host PC 100 are rigidly coupled to provide indirect haptic feedback to the host PC 100 user. The haptic feedback module 230 generally uses a vibration motor, a piezo actuator 250 or a solenoid actuator 240.

In addition, when indirect haptic feedback is provided to the host PC 100 by vibration of the haptic feedback module 230, the transmission distance of the tactile stimulus is in contact with the host PC 100 at the connector connection part 120 of the host PC 100. It will be the distance to the user's pointing object (eg finger). Therefore, the greater the transmission distance (that is, the farther the finger is in contact with the surface of the host PC 100 with the connector connector 120), the smaller the reaction time and the magnitude of the reaction. However, considering that the size of the conventional host PC 100 and the add-on device 200 is rigidly coupled to the host PC 100, such minute changes do not significantly affect the purpose of providing haptic feedback to the user. It can be ignored.

( Add-on  With device Haptic Feedback  system)

Hereinafter, the haptic feedback system including the add-on device 200 according to the present invention will be described. First, FIG. 3 shows a block diagram of a haptic feedback system in which the add-on device 200 is rigidly coupled to the host PC 100.

And they are electrically connected to each other. When the electrical connection occurs, the host PC 100 recognizes the add-on device 200 and starts the application program 110. The application program 110 outputs an input signal from the host PC 100, and the output input signal is transmitted to the add-on device 200.

The input signal is applied to the haptic feedback module 230 as an electrical signal by the electric circuit means 220. The electrical circuit unit 220 calculates an input signal from the microprocessor 221 as an electrical signal capable of reacting the haptic feedback module 230. The electrical signal is transmitted to the haptic feedback module 230 by the electronic driver 222. The haptic feedback module 230 connected to the electronic driver 222 may be provided in plurality. Each of the haptic feedback modules 230 that have received an electrical signal generates three-dimensional movement.

As described above, the haptic feedback module 230 is not limited in kind as long as it generates three-dimensional movement in response to an electrical signal. In general, a vibration motor, a piezo actuator 250 or a solenoid actuator 240 is used. In addition, the add-on device 200 may include a separate power supply means to receive power, but may be operated without a separate power supply means by being electrically connected to the host PC 100.

As shown in FIG. 4, the upper plate 241 to which the magnet 242 is attached and the lower plate 243 to which the coil 244 is attached are provided. When electricity is applied to the solenoid actuator 240, the magnetic force is generated to move up and down, causing the add-on device 200 to vibrate.

As the add-on device 200 vibrates, the rigid-coupled host PC 100 also vibrates. FIG. 5 is a graph measuring vibration magnitudes on the surface of the host PC 100 in the add-on device 200 using the haptic feedback module 230 including the solenoid actuator 240. As shown in Figure 5, it can be seen that the response period is less than 10msec. Slow response speed is an obstacle to the utilization of various application programs 110, but the present invention can be utilized in conjunction with various application programs 110 by having a fast response speed.

The add-on device 200 vibrates by the vibration of the piezo actuator 250, and indirect haptic feedback is provided to the host PC 100 rigidly coupled to the add-on device 200. FIG. 7 is a graph showing the magnitude of the surface of the host PC 100 vibrating by vibrating the haptic feedback module 230 constructed using the piezo actuator 250. As shown in Figure 6, having a response period of less than 10ms (msec) can be utilized in conjunction with various application programs (110).

It may be provided. Such coupling means may be provided by various means that can increase the coupling force between the add-on device 200 and the host PC within the range that can be obvious to those skilled in the art.

When the add-on device 200 is combined, the host PC 100 recognizes the application program 110 in the host PC 100 (S20). When the application 110 is started, an input signal according to the application 110 is generated as the user uses the host PC 100. Then, the input signal of the host PC 100 is transmitted to the add-on device 200 (S30). Since the host PC 100 and the add-on device 200 are electrically coupled, the add-on device 200 that receives the input signal transmits an electrical signal to the haptic feedback module 230 by the electric circuit 220. Will be (S40).

 The electrical circuit unit 220 is to electrically connect the haptic feedback module 230 and the connector 210 may vary according to the configuration of the specific haptic feedback module 230. As a specific example, the microprocessor 221 receives an input signal and transmits an electrical signal to the electronic driver 222, and the electronic driver 222 transmits an electrical signal to the haptic feedback module 230. The haptic feedback module 230 may be provided in plurality, and the electronic driver 222 transmits an electrical signal to each haptic feedback module 230.

The haptic feedback module 230 receives the electrical signal and vibrates to provide indirect haptic feedback to the host PC 100 rigidly coupled with the add-on device 200 (S50). The haptic feedback module 230 generates a three-dimensional movement by receiving an electrical signal and uses a vibration motor, a piezo actuator 250, a solenoid actuator 240, or the like. As described above, since the response period of the indirect haptic feedback provided by the host PC 100 is less than 10 ms, it may be used in conjunction with various application programs 110.

If the input signal continues to exist in the host PC 100, the user of the host PC 100 continues to receive haptic feedback in real time (S60). This haptic feedback continues until the add-on device 200 is separated from the host PC 100 (S70).
