First, FIG. 1 shows a state in which a human hand is holding the vibrator 10 vibrating at a specific frequency. Therefore, a person can feel the vibration by the vibration of the vibrator.

In FIG. 1, when the first vibrator 10-1 located on the left side and the second vibrator 10-2 on the right side are held, even though there is a difference in the frequencies oscillating with each other, the difference is only 5 to 10 Hz. If you do, the person will not feel the difference in frequency, that is, the person will feel the same sense, for example, the first vibrator 10-1 on the left vibrates at 250 Hz and the second on the right. If the vibrator 10-2 vibrates at 254 Hz, a person does not sense the difference between them.

FIG. 2A shows a time versus amplitude graph in the state of holding the first vibrator 10-1 vibrating at the first specific frequency f ₁ . 2B illustrates a time versus amplitude graph in a state in which the first vibrators 10-1 vibrating at the same first specific frequency f ₁ are in contact with each other. 2C illustrates a time versus amplitude graph in a state in which the first vibrator 10-1 and the second vibrator 10-2 vibrating at different specific frequencies are in contact with each other.

It can be recognized that the sense that is different from the sense that was provided in. This sense corresponds to the sense according to the beat phenomenon (50).

The present invention can provide a new haptic feedback by using a change in the sense when these two vibrators are in contact. The beat phenomenon 50 is generated when a vibrator having a small difference in frequency is in contact. For example, the displacement function of the vibrator oscillating at the first specific frequency f ₁ and the displacement function of the oscillator oscillating at the second specific frequency f ₂ different from the first specific frequency f ₁ are as follows. It is represented by Equation 1.

<Using the beat phenomenon Haptic Feedback  How to provide and how to provide services Example >

Hereinafter, a haptic feedback providing method using a beat phenomenon according to an embodiment of the present invention will be described. 7 is a flowchart illustrating a haptic feedback providing method using a beat phenomenon according to an embodiment of the present invention.

The haptic feedback providing method uses the haptic feedback providing apparatus described above. First, a first portable terminal 100-1 having a first haptic feedback module vibrating at a first specific frequency by an electrical signal according to an external pressure and vibrating at a second specific frequency by an electrical signal according to an external pressure The second mobile terminal 100-2 including the second haptic feedback module is brought into contact with each other (S10).

Then, in the contacted state, pressure is applied to the upper panel 121 of the first portable terminal 100-1 and the upper panel 121 of the second portable terminal 100-2 with a pointing object such as a finger 1. It is added (S20). When pressure is applied to the outside, the first portable terminal 100-1 and the second portable terminal 100-2 each generate an electrical signal according to the external pressure, and the first of the first portable terminal 100-1 is generated. The haptic feedback module vibrates, and the second haptic feedback module of the second mobile terminal 100-2 vibrates.

In addition, when the pressure is applied in the contacted state, the determination means determines whether the beat phenomenon 50 is generated (S30). As described above, when the first specific frequency f1 and the second specific frequency f2 have a predetermined frequency difference, each of the first portable terminal 100-1 and the second portable terminal 100-2 As the haptic feedback module 140 vibrates, the beat phenomenon 50 occurs. Accordingly, the third haptic feedback 40 according to the beat phenomenon 50 is provided to the contact finger 1 (S40). In addition, when the first specific frequency and the second specific frequency are the same, even if pressure is applied in a contact state, the beat phenomenon 50 does not occur, the frequency is the same, and the third haptic feedback 40 having a large amplitude is provided. do.

The haptic feedback providing method according to an embodiment of the present invention is to provide a haptic feedback according to the haptic feedback and other beat phenomenon 50 of each mobile terminal 100 in a state where no contact occurs.

In addition, in an embodiment of the present invention by applying the method of providing the haptic feedback using the above-described beat phenomenon 50 to determine whether a particular group, to provide a social network service or a region-based service between users belonging to a specific group There is this.

8 is a flowchart illustrating a method for providing a service between specific groups using the beat phenomenon 50 according to an embodiment of the present invention. First, a specific group is determined, and the mobile terminal 100 providing haptic feedback used by users belonging to the specific group is assigned to a specific frequency (S100). That is, the haptic feedback module 140 of the mobile terminal 100 used by users in a specific group all vibrate at the same specific frequency.

In addition, the portable terminal 100 used by the user belonging to a specific group is brought into contact with an arbitrary portable terminal (S200). The determination means determines whether the contact is made, and the user applies pressure to the mobile terminal 100 and the arbitrary mobile terminal 100 belonging to a specific group. When the pressure is applied, each of the haptic feedback module 140 of the mobile terminal 100 belonging to a specific group and the haptic feedback module 140 built in any mobile terminal 100 vibrate.

Then, the determining means determines whether the beat phenomenon (50) occurs (S300). As described above, as described above, if the beat phenomenon 50 occurs, the frequency of the arbitrary portable terminal 100 will correspond to a different frequency than the specific frequency assigned to a specific group, the beat phenomenon 50 occurs Instead, if only the amplitude is changed, the frequency of any mobile terminal 100 will be equal to a specific frequency. Therefore, if the beat phenomenon 50 does not occur, the determining means determines that the portable terminal 100 corresponds to a specific group (S400).

If it is determined that any mobile terminal 100 in contact is within a specific group, it provides various social network services or location-based services between the mobile terminals 100 in contact (S500). ).

Social network services are a one-man media, one-person community that allows individuals to share their information on a network and communicate with each other.Typical social network services include Cyworld, Twitter, Facebook, MySpace, LinkedIn, Vivo, H15, XING, etc. However, these examples are intended to present specific embodiments, and the scope of the present invention should not be construed as being limited to these specific embodiments.

In addition, the area-based service is to provide a variety of services to the user based on the location information. There are large cell system using mobile communication base station and GPS system using satellite navigation system. The cell system began to be developed and distributed around 2000, and it is difficult to find the exact position because the error range of the position can be up to several kilometers. On the other hand, because it uses a repeater, it is advantageous to be able to find a location in a building or underground.

The GPS method is a method in which a chip embedded in a mobile phone reads location information sent from a satellite and informs a base station. It is a service that appeared after the cellular method, and the error range of the location is only a few hundred meters so that the location can be known almost accurately. However, due to the characteristics of satellite signals, it is almost impossible to use in high-rise buildings or indoors where reflection and refraction are good. Information obtained through location-based services can be used to identify and track the location of people and vehicles, as well as to connect to rescue agencies by pressing the emergency button on the phone when in danger in remote areas such as mountains or deserts. Can be received.

In addition, the weather service in a certain place where a mobile phone user is located, a comprehensive alert notification service for subscribers in a certain area, a traffic information service for finding shortcuts, a life information service such as nearby department stores, medical institutions, theaters, restaurants, etc. Various services such as telematics service provided are possible.
