DETAILED DESCRIPTION
Example embodiments of the present application are further described in detail with reference to accompanying drawings and embodiments. The following embodiments are used to describe the present application, but are not intended to limit the scope of the present application.
A person skilled in the art understands that sequence numbers of the following steps do not mean execution sequences in embodiments of the present application. The execution sequences of the steps should be determined according to functions and internal logic of the steps, and should not be construed as any limitation on the embodiments of the present application.
In one or more of the embodiments of the present application, a wave signal is a signal transmitted in a form of a wave. An ultrasonic wave is an acoustic wave and with frequency higher than 20000 Hz, the ultrasonic wave has desirable directivity and a strong penetration capability, and therefore, relatively concentrated sound energy is easily obtained. The ultrasonic wave has a long transmission distance in water, and around 65% of constituents of a human body are water; therefore, ultrasonic wave information is desirably transmitted by using a human body as a transmission medium. Besides, frequency of the ultrasonic wave is beyond the human hearing range; therefore, a user cannot perceive the existence of an ultrasonic wave signal, and consequently the user is not affected by noise. In addition, an electromagnetic wave signal with frequency lower than 100 MHz is also desirably transmitted through a human body, and is desirably applicable to the embodiments of the present application.
FIG. 1 is a flowchart of an interaction method according to an embodiment of the present application, where the interaction method may be implemented in, for example, an interaction system. As shown in FIG. 1, the method comprises:
S120: In response to contact between a user body and an object, receive a wave signal that is sent by the object and is transmitted by using a medium comprising at least a part of the user body.
In the method according to this embodiment of the present application, in response to contact between a user body and an object, a wave signal that is sent by the object and is transmitted by using a medium comprising at least a part of the user body is received, which can provide data support for obtaining related information of the object. In this way, in a process of contact between the user body and an external object, information interaction with the contacted object is naturally and efficiently completed.
Specifically, the object may periodically send the wave signal, for example, a domestic daily utensil (for example, a cup or a door handle) of a user sends the wave signal each second; or the object may send the wave signal as triggered by the user, for example, in response to pressing, by the user, a key, a domestic daily utensil of the user starts to send the wave signal.
The contact is not limited to direct contact, and also comprises indirect contact (for example, holding a mouse while wearing a glove) and a case in which a distance between the user body and a corresponding object is less than a preset distance (for example, 0.1 mm).
The user body may comprise clothes that the user wears, an accessory that the user wears, or the like, such as a glove that the user wears. The object may comprise non-life entities such as a desk, a cup, and a mouse, and may also comprise life entities such as a human body, an animal, and a tree.
The at least a part of the user body may be positions such as the head, the hand, and the leg of the user, and the at least a part of the user body is related to a position in which the user body contacts the object, for example, when a finger of the user contacts the object, the at least a part of the user body usually comprises the hand of the user. In consideration of frequency at which different positions of a human body contact an external object, the at least a part of the user body is more possibly a hand of the user, for example, a palm of the user or a finger of the user. Therefore, the wave signal is received on a hand of the user, which complies with a life habit of the user to a greater extent, and is more natural and efficient.
Referring to FIG. 2, in an example embodiment of the present application, the method may further comprise:
S140: Identify the object according to a signal characteristic of the received wave signal.
The inventor finds in researches that affected by a material, a texture, a shape, a size, a type, a structure, and the like that are intrinsic to an object, signal characteristics of a wave signal received after the same wave signal penetrates through different objects are obviously different. Therefore, in an example embodiment, a signal source may be disposed in (or above) each object, the signal source is made to transmit the same initial wave signal, and then the object is identified according to a signal characteristic, corresponding to a known object, of a wave signal and the signal characteristic of the received wave signal. The identifying the object according to a signal characteristic, corresponding to a known object, of a wave signal and the signal characteristic of the received wave signal may comprise:
S141: Create a classifier according to the signal characteristic, corresponding to the known object, of the wave signal.
S142: Perform a classification calculation according to the classifier and the signal characteristic of the received wave signal, and identify the object according to a calculation result.
The signal characteristic, corresponding to the known object, of the wave signal may be pre-determined by means of an experiment and pre-stored. For example, a manufacturer or the user pre-holds different objects, and separately records corresponding signal characteristics of the wave signal, so as to obtain the signal characteristic, corresponding to the known object, of the wave signal, where the signal characteristic, corresponding to the known object, of the wave signal may be stored in a device storage or a network server, so that the signal characteristic, corresponding to the known object, of the wave signal is invoked in actual use of the method.
In another example embodiment, signal sources in different objects may also be made to correspondingly send different initial wave signals, signal characteristics, corresponding to known objects, of wave signals are pre-obtained, and then the objects can also be identified according to signal characteristics of received wave signals.
In addition, the inventor finds in researches that if an initial wave signal is sent at a fixed position of a relatively large object, contact between the user body and different positions of the object also cause different signal characteristics of received wave signals. In this case, a specific position in which the user body contacts the object can be identified according to pre-obtained signal characteristics, corresponding to different positions of the object, of wave signals and a signal characteristic of a received wave signal.
Therefore, in step S140, the identifying the object may be directly obtaining a name of the object, for example, telling the user that a cup is currently held; may also be obtaining, by means of identification, attribute information such as a material, a texture, a shape, a size, a structure, and the like of the object, where the user can determine what the object is according to the attribute information; or may further be identifying a position in which the user body contacts the object.
The signal characteristic of the wave signal may be related to at least one of an amplitude, a phase, and a frequency spectrum of the wave signal. Specifically, the signal characteristic of the wave signal may comprise at least one of a fingerprint, an average value, and a difference, wherein the fingerprint may be formed by at least one of the amplitude of the wave signal, the phase of the wave signal, and the frequency spectrum of the wave signal; the average value may be an average value of at least one of the amplitude of the wave signal, the phase of the wave signal, and the frequency spectrum of the wave signal; and the difference may be a difference of at least one of the amplitude of the wave signal, the phase of the wave signal, and the frequency spectrum of the wave signal.
Referring to FIG. 3, in an example embodiment of the present application, the method may further comprise:
S160: Execute a corresponding operation according to an identification result.
The executing a corresponding operation may comprise switching a mode, inputting content, matching a device, prompting a user, and the like.
For example, in the case in which the identification result indicates that a hand of the user touches a steering wheel, a smart phone of the user may be controlled to switch to a driving mode; in this case, if receiving information, the smart phone may directly broadcast information by using a speech to improve driving safety.
Or, for example, during a game of the user, corresponding control instructions may be input according to identified keys of different shapes or identified different positions of the same key that the user contacts.
Or, for example, when the identification result indicates that a hand of the user contacts a Bluetooth headset, a smart phone of the user can be controlled to automatically match and establish a connection with the Bluetooth headset.
Or, in the case in which it is inconvenient for the user to observe, the user can be prompted according to the identification result. For example, in the case in which a blind user contacts a cup, the blind user may be prompted that a cup is currently contacted, and the user may be further prompted whether the cup has water.
In addition, an embodiment of the present application further provides a computer readable medium, which comprises a computer readable instruction that performs the following operations when being executed: executing the operation of step S120 of the method in the example embodiment shown in FIG. 1.
In conclusion, in the method according to this embodiment of the present application, a contacted object can be identified according to a signal characteristic of a received wave signal, and a corresponding operation such as switching a mode, inputting content, matching a device, and prompting a user can be performed according to an identification result. In this way, information interaction between a user and the object or a corresponding device is naturally and efficiently completed.
FIG. 4 is a schematic structural diagram of modules of an interaction system according to an embodiment of the present application, where the interaction system may be a wearable device such as a wrist strap or a ring.
As shown in FIG. 4, the interaction system 400 comprises:
a receiving apparatus 410, configured to: in response to contact between a user body and an object, receive a wave signal that is sent by the object and is transmitted by using a medium comprising at least a part of the user body.
In the system according to this embodiment of the present application, in response to contact between a user body and an object, a wave signal that is sent by the object and is transmitted by using a medium comprising at least a part of the user body is received, which can provide data support for obtaining related information of the object. In this way, in a process of contact between the user body and an external object, information interaction with the contacted object is naturally and efficiently completed.
Specifically, the object may periodically send the wave signal, for example, send the wave signal each second, or send the wave signal as triggered by a user, for example, send the wave signal in response to pressing, by the user, a key.
The contact is not limited to direct contact, and also comprises indirect contact (for example, holding a mouse while wearing a glove) and a case in which a distance between the user body and a corresponding object is less than a preset distance (for example, 0.1 mm).
The user body may comprise clothes that the user wears, an accessory that the user wears, or the like, such as a glove that the user wears. The object may comprise non-life entities such as a desk, a cup, and a mouse, and may also comprise life entities such as a human body, an animal, and a tree.
The at least a part of the user body, that is, a position related to a position in which the interaction system is worn, may be positions such as the head, the hand, and the leg of the user. In consideration of frequency at which different positions of a human body contact an external object, an interaction process is more natural and efficient when the interaction system is worn on the hand of the user, for example, the interaction system is worn in a position such as a wrist of the user or a finger of the user. Besides, to improve determining accuracy of the interaction system, a material such as silica gel or another flexible material that facilitates wave signal transmission may be provided between the interaction system and the user body.
Referring to FIG. 5, in an example embodiment of the present application, the interaction system further comprises:
an identification apparatus 420, configured to identify the object according to a signal characteristic of the received wave signal.
The inventor finds in researches that affected by a material, a texture, a shape, a size, a type, a structure, and the like of an object, signal characteristics of the same wave signal received after the wave signal penetrates through different objects are obviously different. Therefore, in an example embodiment, a signal source may be disposed in (or above) each object, the signal source is made to transmit the same initial wave signal, and then the object is identified according to a signal characteristic, corresponding to a known object, of a wave signal and the signal characteristic of the received wave signal.
The signal characteristic, corresponding to the known object, of the wave signal may be pre-determined by means of an experiment and pre-stored. For example, a manufacturer or a user pre-holds different objects, and separately records corresponding signal characteristics of the wave signal, so as to obtain the signal characteristic, corresponding to the known object, of the wave signal, where the signal characteristic, corresponding to the known object, of the wave signal may be stored in a device storage or a network server, so that the correspondence is invoked in actual use of the method. Correspondingly, referring to FIG. 5, the interaction system 400 may further comprise:
a determining apparatus 430, configured to pre-determine the signal characteristic, corresponding to the known object, of the wave signal; and
a storage apparatus 440, configured to pre-store the signal characteristic, corresponding to the known object, of the wave signal.
In another example embodiment, signal sources in different objects may also be made to correspondingly send different initial wave signals, signal characteristics, corresponding to known objects, of wave signals are pre-obtained, and then the objects can also be identified according to signal characteristics of received wave signals.
In addition, the inventor finds in researches that if an initial wave signal is sent at a fixed position of a relatively large object, contact between the user body and different positions of the object also cause different signal characteristics of received wave signals. In this case, in another example embodiment, a specific position in which the user body contacts the object can further be identified according to pre-obtained signal characteristics, corresponding to different positions of the object, of wave signals and a signal characteristic of a received wave signal.
Therefore, the identifying, by the identification apparatus 420, the object may be directly obtaining a name of the object, for example, telling the user that a cup is currently held; may also be obtaining, by means of identification, attribute information such as a material, a texture, a shape, a size, a structure, and the like of the object, where the user can determine what the object is according to the attribute information; or may further be identifying a position in which the user body contacts the object.
The signal characteristic of the wave signal may be related to at least one of an amplitude, a phase, and a frequency spectrum of the wave signal. Specifically, the signal characteristic of the wave signal may comprise at least one of a fingerprint, an average value, and a difference, wherein the fingerprint may be formed by at least one of the amplitude, the phase, and the frequency spectrum of the wave signal; the average value may be an average value of at least one of the amplitude, the phase, and the frequency spectrum of the wave signal; and the difference may be a difference of at least one of the amplitude, the phase, and the frequency spectrum of the wave signal.
Referring to FIG. 6, in an example embodiment of the present application, the system 400 may further comprise:
an execution apparatus 450, configured to execute a corresponding operation according to an identification result.
The executing a corresponding operation may comprise switching a mode, inputting content, matching a device, prompting a user, and the like.
For example, in the case in which the identification result indicates that a hand of the user touches a steering wheel, the system 400 may control a smart phone of the user to switch to a driving mode; in this case, if receiving information, the smart phone may directly broadcast information by using a speech to improve driving safety.
Or, for example, during a game of the user, the system 400 may input corresponding control instructions according to identified keys of different shapes or identified different positions of the same key that the user contacts.
Or, for example, in the case in which the identification result indicates that a hand of the user contacts a Bluetooth headset, the system 400 may control a smart phone of the user to automatically match and establish a connection with the Bluetooth headset.
Or, in the case in which it is inconvenient for the user to observe, the system 400 may prompt the user according to the identification result. For example, in the case in which a blind user contacts a cup, the blind user may be prompted that a cup is currently contacted, and the user may be further prompted whether the cup has water.
FIG. 7 is a schematic diagram of an application scenario of an interaction system according to an embodiment of the present application. As shown in FIG. 7, a user 710 is a blind person, and wants to find a cup 730 on a table 720 to drink water. When a finger of the user 710 contacts the table 720, a wrist strap 740 worn on a wrist of the user 710 receives a wave signal sent by a first signal transmitter 751, further identifies that an object that the user currently contacts is the table 720, and prompts the user that the table 720 is currently contacted. Then, the user 710 continues to grope on the table 720; when a finger of the user 710 contacts the cup 730, the wrist strap 740 receives a wave signal sent by a second signal transmitter 752, further identifies that an object that the user currently contacts is the cup 730, and prompts the user that the cup 730 is currently contacted.
The first signal transmitter 751 and the second signal transmitter 752 may use a surface mounting structure to facilitate attachment to an object surface, and certainly the first signal transmitter 751 and the second signal transmitter 752 may also be respectively embedded in the table 720 and the cup 730. In addition, in the case in which the user 710 contacts the table 720, the wrist strap 740 may further identify and prompt the user 710 whether the table surface or a table leg is currently contacted; in the case in which the user 710 contacts the cup 730, the wrist strap 740 may further identify and prompt the user 710 whether the cup 730 has water, so that the user 710 conveniently drink.
In conclusion, in the system according to this embodiment of the present application, an object can be identified according to a signal characteristic of a received wave signal, and a corresponding operation such as switching a mode, inputting content, matching a device, and prompting a user can be performed according to an identification result. In this way, information interaction between a user and the object or a corresponding device is naturally and efficiently completed.
