DETAILED DESCRIPTION

A detailed description of the technical solutions of the embodiments of the present disclosure is provided below in view of the accompanying drawings. It should be understood that the embodiments described below are representative embodiments of the present disclosure rather than a complete disclosure of the every possible embodiment. The present disclosure can also include any other embodiments that can be derived from these disclosed embodiments by a person with ordinary skill in the art without any additional inventive work. It is to be understood that other embodiments can be used and structural changes can be made without departing from the scope of the embodiments of this disclosure.

This generally relates to a method for exchanging information between two devices. As referred hereinafter, a device can be any electronic device capable of connecting to a network for transmitting and receiving data. Such device can include, but are not limited to, PCs, Macs, desktop computers, laptop computers, tablet PCs, smartphones including iPhones, Android phones, Windows phones, and Blackberries, e-readers, in-car communication devices, televisions and other consumer electronic devices with sufficient network capabilities. Furthermore, a device can also be referred to as a terminal (i.e., “device” and “terminal” are interchangeable terminologies). For example, a mobile terminal can be any mobile device such as a mobile phone or a tablet PC. In some embodiments, the mobile terminal can include a camera, a flash, and the necessary program to process image data. The camera can optionally include an adjustable lens. The mobile terminal can also optionally include an accelerometer.

As referred hereinafter, a service device (or server) can also be any electronic device capable of communicating with one or more other devices. A service device (or server) can be a desktop computer, laptop computer, or another mobile terminal. A service device (or server) can, but is not required to, perform one or more functions including, but not limited to, providing a network service, hosting network-based applications, routing information among other devices, and providing access to a network for other devices. In short, a service device (or server) can simply be another device capable of communicating with another device over a network. As described in the embodiments below, the service device can be connected to a display device (or display). The display device can be a part of the service device (e.g., the display of a laptop PC) or connected to the service device using a cable or a wireless connection. For example, the display device can be a monitor connected to a desktop PC.

The mobile terminal and the service device can be preferably connected via a wireless networks. A communication link can be established between the mobile terminal and the service device using any suitable means. In one embodiment, a link can be established by, for example, the mobile terminal reading a code (QR code) including connection information displayed on the display connected to the service device and using the connection information to establish a communication link with the service device. The connection information can be, for example, an IP address, Wi-Fi ID, or other types of identification information and/or network protocol information that may be required to establish the communication link.

In operation, information displayed on the mobile terminal can be transmitted in a visual way to the display connected to the server using embodiments of the disclosure. For example, the user may have the login information for an application (e.g., a microblog or QQ by Tencent) displayed on his smartphone. If he would like to have the same information automatically displayed on his laptop computer, using the disclosed methods, he can simply move the smartphone to close proximity of the display of the laptop computer. The smartphone can detect a distance between itself and the display of the laptop computer to determine if it is close enough to the display. This detection can be based on, for example, the brightness of a picture taken by the camera on the smartphone as it moves closer to the display of the laptop. Because the display of the laptop can be reflective, as the smartphone moves closer to the display, a picture taken by the camera on the smartphone can have a brightness exceeding a particular threshold.

As described in detail below, various mechanisms can also be used to indicate when the camera can take the picture to be used to determine whether the smartphone is in close proximity of the display. For example, if the smartphone is equipped with an accelerometer, an acceleration-to-deceleration motion captured by the accelerometer can be used as an indication that the mobile phone has been moved closer to the display and trigger the camera to take a picture. Alternatively, if the camera on the smartphone is equipped with an adjustable lens, if the lens is adjusting continuously to focus on an object, it can indicate that the smartphone is being moved closer to the display and that a picture can be taken to be used to determine whether the smartphone is close enough to the display.

After the smartphone determines that it is in close proximity of the display of the laptop, it can inform the laptop in this regard and the laptop can notify both the display and the smartphone to prepare for a data transfer. When both devices are set for the transfer, an animation can be initiated on the smartphone that shows the information being transferred (e.g., the user login information) being moving off the screen of the smartphone. As the information disappears on the screen of the smartphone, the same information can gradually appear on the display of the laptop to create a visual effect that the information is being moved from the smartphone to the laptop screen. As such, the user is no longer required to re-type the information on the laptop or transmit the information using email, instant messaging, or other messaging applications. All he needs to do is to move the smartphone closer to the display of the laptop and the information can be automatically transferred. This method of exchanging information between two devices can be used to transfer any suitable type of information, such as a web link, an email address, etc. The type of information being transferred is not limited to text information, but can also include other types of data, such as image, audio, and video data. Various embodiments of the disclosure are described in detail below in view of the figures.

The embodiments of the disclosure provide information exchanging methods, devices, and systems to simplify the interactions between a mobile device and a service device, reducing manual participation by the user, and improving user experience. Exemplary embodiments are described in detail below.

Referring to FIG. 1, FIG. 1 is a flowchart illustrating the exemplary steps of an information exchanging method, according to a first embodiment of the disclosure. The first embodiment is described from the mobile terminal's perspective. As illustrated in FIG. 1, the information exchanging method can include the following exemplary steps.

101. The mobile terminal can establish a communication link with a service device connected to a display device.

In the embodiments of the disclosure, a mobile terminal can be a smartphone, PDA, or any other touch screen equipped mobile terminal. Alternatively, it can also be other touch screen equipped mobile internet devices (MIDs).

In this embodiment, the display device connected to the service device can be a stand-alone display. Alternatively, the service device can be a smart terminal equipped with a display, such as a tablet PC, laptop PC, smart recharging terminal, smart trading terminal, etc.

In this embodiment, the service device can be a server, host computer, or other terminals providing external service capabilities.

Optionally, the mobile terminal can establish a communication link with the service device connected to the display device using the following exemplary steps.

Step 1: the mobile terminal can read a 2-dimensional code displayed on a human-computer interface of the display device connected to the service device.

Step 2: the mobile terminal can decode the 2-dimensional code to obtain transfer protocol information.

The mobile terminal can obtain Hypertext Transfer Protocol (HTTP) information or other transfer protocol information capable of establishing a communication link, after decoding the 2-dimensional code.

Step 3: the mobile terminal can transmit a communication link request to the service device in accordance with the transfer protocol information.

Step 4: the service device can return a response to the communication link request to the mobile terminal to establish the communication link between the mobile terminal and the service device.

In this embodiment, the mobile terminal can read the 2-dimensional code displayed on the human-computer interface of the display device connected to the service device and decode the transfer protocol information in the 2-dimensional code to establish a communication link with the service device, thus effectively improving the efficiency of establishing a communication link.

If the hardware of the mobile terminal and the service device has the capability, the communication link can be completed using near field communication technology.

102. The mobile terminal can detect whether it is in close proximity of the display device. If yes, it can transmit a first command including information to the service device, to trigger the service device to transmit a second command including the information to the display device so that the display device can display the information.

In this embodiment, the information in the first command can be user identity information needed to log into an application program (e.g., a microblog, QQ). The user identity information can include a picture, user name, and/or user ID. Alternatively, the information in the first command can be the data to be exchanged with the service device after the user successfully logs into the particular application program (e.g., microblog, QQ). Alternatively, the information in the first command can be a Uniform/Universal Resource Locator (URL) for visiting a particular network resource.

In this embodiment, after reading the 2-dimensional code displayed on the human-computer interface of the display device connected to the service device and decoding the 2-dimenstional code, the mobile terminal can obtain display device information. The information can include, for example, an ID or serial number of the display device. As such, the communication link request transmitted from the mobile terminal to the service device based on the transfer protocol information can include the display device information so that the service device can recognize the corresponding display device and transmit a second command including the information from the first command to the display device so that the corresponding display device can display this information. This method can allow the service device to accurately locate the display device in close proximity of the mobile device even when the service device is connected to multiple display devices. Thus, the service device can transmit the second command including the information from the first command to the display device in close proximity of the mobile terminal.

Optionally, the mobile terminal detecting whether it is in close proximity of the display device in step 102 can include the following exemplary steps.

Step 1: the mobile terminal can turn on a flash and capture image data, and perform pixel optimization on the image data to obtain an image.

In this embodiment, when the camera lens of the mobile terminal captures a designated image or a designated area in a particular color displayed on the human-computer interface of the display device, the mobile terminal can turn on the flash immediately and capture image data.

Step 2: the mobile terminal can determine whether a brightness of the image exceeds a predetermined threshold. If yes, it can determine that the mobile terminal is in close proximity of the display device.

In this embodiment, if the mobile terminal is in close proximity of the display device, the mobile terminal can turn on the flash and capture the image data. The brightness of the image obtained from performing pixel optimization on the image data can be greatly enhanced because of the reflective effect of the display of the display device. Thus, as long as the predetermined threshold is reasonably set and the brightness of the image is determined to be above the threshold, it can be determined that the mobile terminal is in close proximity of the display device.

Optionally, the mobile terminal detecting whether it is in close proximity of the display device of step 102 can include the following exemplary steps.

Step 1: the mobile terminal can capture a first image data and perform pixel optimization on the first image data to obtain a first image.

In this embodiment, when capturing a target image displayed on the human-computer interface of the display device, the mobile terminal can turn off the flash and capture a first image data, which can be the target image data, and perform pixel optimization on the first image data to obtain a first image.

Step 2: the mobile terminal can compare the first image with a predetermined target image to determine if they are the same. If yes, it can turn on the flash and capture a second image data and performing pixel optimization on the second image data to obtain a second image.

In this embodiment, a target image can be pre-stored at the mobile terminal. The target image can be a designated area of a display of the display device. For example, the target image can be the area of the display of the display device that displays the information in the second command transmitted by the service device.

After determining that the first image and the target image are the same, the mobile terminal can determine that it is facing the designated area of the display of the display device at that moment.

Step 3: the mobile terminal can determine whether a difference between a brightness of the first image and a brightness of the second image is above a predetermined threshold. If yes, it can determine that the mobile terminal is in close proximity of the display device.

If the mobile terminal is facing the designated area of the display of the display device and in close proximity of the display device, the mobile terminal can turn on the flash and capture a second image data. In addition, the brightness of the second image obtained from performing pixel optimization on the second image data can be greatly enhanced because of the reflective effect of the display of the display device. Thus, as long as the predetermined threshold is reasonably set and the difference in the brightness of the second image and the brightness of the first image is above the threshold, it can be determined that the mobile terminal is in close proximity of the display device.

Optionally, before capturing the first image data and performing pixel optimization on the first image data to obtain a first image, the mobile terminal can also perform the following step.

The mobile terminal can use an accelerometer to detect whether the mobile terminal produces an acceleration-to-deceleration action. If so, the mobile terminal can perform the above-described capturing the first image data and performing pixel optimization on the first image data to obtain a first image.

When the mobile terminal uses the accelerometer to detect that it has produced an acceleration-to-deceleration action, it can mean that the mobile terminal is gradually moving closer to the display device. In other words, in this embodiment, the mobile terminal can first use the accelerometer to detect that the mobile terminal has produced an acceleration-to-deceleration action, and then be triggered to detect if it is in close proximity of the display device.

Optionally, before capturing a first image data and performing pixel optimization on the first image data to obtain a first image, the mobile terminal can perform the following step.

The mobile terminal can detect whether a camera lens set to a continuous-focusing mode is focusing continuously. If so, the mobile terminal can perform the above-described capturing the first image data and performing pixel optimization on the first image data to obtain a first image.

When the mobile terminal detects a camera lens of the mobile terminal being set to a continuous-focusing mode is focusing continuously, it can mean that the mobile terminal is gradually moving closer to the display device. In other words, in this embodiment, the mobile terminal can first detect that a camera lens of the mobile terminal being set to a continuous-focusing mode is focusing continuously, and then be triggered to detect if it is in close proximity of the display device.

Based on the above description, the method illustrated in FIG. 1 can simplify the interaction process between the mobile terminal and the service device, reduce manual participation by the user, and thus improving user experience. In addition, in this embodiment, the information transmitted by the mobile terminal can be displayed by the display device. This can, to certain extent, visually present the interactions between the mobile terminal and the server, making the interactions between the mobile terminal and the server more vivid.

Referring to FIG. 2, FIG. 2 is a flowchart illustrating the exemplary steps of an information exchanging method, according to a second embodiment of the disclosure. The second embodiment is described from the perspective of the service device. As illustrated in FIG. 2, the information exchange method can include the following steps.

201: a service device connected to a display device can establish a communication link with a mobile terminal.

Optionally, the service device connected to a display device can establish a communication link with the mobile terminal via the following exemplary steps.

Step 1: the service device can receive a communication link request transmitted by the mobile terminal.

The communication link request transmitted by the mobile terminal can be a 2-dimensional code displayed on the human-computer interface of the display device connected to the service device. After decoding the 2-dimensional code to obtain the transfer protocol information, the request can be transmitted to the service device in accordance with the transfer protocol information.

Step 2: the service device can return a response to the communication link request to the mobile terminal to establish the communication link between the mobile terminal and the service device.

202: the service device can receive a first command including information transmitted from the mobile terminal, the first command transmitted after the mobile terminal detects that it is in close proximity of the service device.

203: the service device can transmit a second command including the information to the display device for the display device to display the information.

Optionally, after the service device connected to the display device establishes a communication link with the mobile terminal, the following steps can be performed.

The service device can notify the display device to display guide information, which can guide the user to move the mobile terminal closer to an area of the display device for displaying information. For example, the guide information displayed on the display device can be, such as, “Please Move Mobile Phone Close to Here.” Using the human-computer interface of display device 1 to display the guide information “Please Move Mobile Phone Close to Here,” as illustrated in FIG. 3, as an example, the guide information “Please Move Mobile Phone Close to Here” can guide the user to put his mobile phone close to an area 2 for displaying user information (e.g., picture, username, and user ID) when logging into the use's QQ account. In this embodiment, the guide information displayed on the display device can enrich the visual interactive effects between the mobile terminal and the server device, thereby improving user experience.

Optionally, after the service device connected to the display device establishes a communication link with the mobile terminal and before the service device receives the first command including the information from the mobile terminal, the following exemplary steps can be performed.

Step 1: the service device can receive a notification transmitted by the mobile terminal. The notification can notify the service device that the mobile terminal has detected itself to be in close proximity of the display device.

Step 2: the service device can notify the display device that detection has completed and receive a notification from the display device regarding entering a set state.

Step 3: the service device can notify the mobile terminal to enter a set state.

In this embodiment, both the service device and the mobile terminal can enter into a set state, avoiding bringing any sudden changes to the operations of both devices.

Based on the above description, the method illustrated in FIG. 2 can simplify the interaction process between the mobile terminal and the server, reduce manual participation by the user, and thus improving user experience. In addition, in this embodiment, the information transmitted by the mobile terminal can be displayed by the display device. This can, to certain extent, visually present the interactions between the mobile terminal and the server, making the interactions between the mobile terminal and the server more vivid.

Referring to FIG. 4, FIG. 4 is a flowchart illustrating exemplary steps of an information exchanging method, according to a third embodiment of the disclosure.

403: the service device, after receiving the first command, can transmit a second command including the information to the display device.

404: the display device can display the information after receiving the second command.

Optionally, the mobile terminal detecting whether it is in close proximity of the display device in Step 402 can be implemented using the method illustrated in FIG. 5. The method can include the following exemplary steps.

501: the mobile terminal can detect, using an accelerometer, whether the mobile terminal produces an acceleration-to-deceleration action. If yes, step 503 can be performed. If no, continue to perform step 501.

502: the mobile terminal can determine whether a camera lens set to a continuous-focusing mode is focusing continuously. If yes, step 503 can be performed. If no, continue to perform step 502.

It should be noted that the mobile terminal can elect to perform one of the above-described steps 501 and 502. Alternatively, the mobile terminal can perform both steps 501 and 502 described above. In particular, when the mobile terminal performs both steps 501 and 502, the order in which the steps are performed is not restricted.

503: the mobile terminal can capture a first image data and perform pixel optimization on the first image data to obtain a first image.

504: the mobile terminal can compare the first image with a target image to determine if they are the same. If yes, step 505 can be performed. If no, the process can end.

505: the mobile terminal can turn on the flash and capture a second image data and perform pixel optimization on the second image data to obtain a second image.

506: the mobile terminal can determine whether a difference between a brightness of the first image and a brightness of the second image is above a predetermined threshold. If yes, perform step 507. If no, the process can end.

507: the mobile terminal can determine that the mobile terminal is in close proximity of the display device.

In the information exchanging method illustrated in FIG. 4, after the mobile terminal detects that it is in close proximity of the display device and before transmitting the first command including information to the service device, the following steps can be performed.

Step 1: the mobile terminal can notify the service device regarding having detected itself being in close proximity of the display device.

Step 2: the service device can notify the display device that the detection has been completed and receive a notification returned from the display device regarding the display device entering a set state.

Step 3: the service device can notify the mobile terminal to enter a set state.

In the information exchanging method illustrated in FIG. 4, after the mobile terminal and the service device connected to the display device establish a communication link, the following steps can be performed.

The service device can notify the display device guide information for guiding a user to move the mobile device close to an information-displaying area of the display device.

Based on the above description, the method illustrated in FIG. 4 can simplify the interaction process between the mobile terminal and the server, reduce manual participation by the user, and thus improving user experience. In addition, in this embodiment, the information transmitted by the mobile terminal can be displayed by the display device. This can, to certain extent, visually present the interactions between the mobile terminal and the server, making the interactions between the mobile terminal and the server more vivid.

Referring to FIG. 6, FIG. 6 is a flowchart illustrating the exemplary process of an information exchanging method, according to a fourth embodiment of the disclosure. The fourth embodiment is described from the perspective of a mobile terminal and a server (e.g., a service device) connected to a display device. As illustrated in FIG. 6, the information exchanging method can include the following steps.

601: the mobile terminal can detect if it is in close proximity of the display device.

Exemplary implementations of the mobile terminal detecting itself being in close proximity of the display device have been discussed in detail in the previous embodiments and is be repeated here.

For example, a mobile terminal being in close proximity of a display device is illustrated in FIGS. 7 and 8a. FIG. 7 provides a front view illustrating a mobile terminal 6 being in close proximity of a display device 1. FIG. 8a is a side view illustrating the mobile terminal 6 being in close proximity of the display device 1. As illustrate in FIG. 7, the human-computer interface of display device 1 can include guide information “Please Place Mobile Phone Close to Here.” This guide information, “Please Place Mobile Phone Close to Here,” can guide the user to move the mobile terminal closer to area 2 of the display device 1 for displaying user information (e.g., picture 4, username 3, and user ID 5) when the user logs into QQ.

602: the mobile terminal can notify the server regarding detecting itself being close to the display device.

603: the server can notify the display device that detection has completed.

604: the server can receive a notification returned from the display device notifying that the display device has entered a set state.

605: the server can notify the mobile terminal to enter a set state.

606: the mobile terminal can enter a set state and calculate a set time and network delay.

607: the mobile terminal can transmit a first command including information to the server.

The information included in the first command transmitted by the mobile terminal can include user information (e.g., picture 4, username 3, and user ID 5) for logging into QQ.

608: after receiving the first command including the information transmitted from the mobile terminal, the server can transmit a second command including the information to the display device, to have the display device display the information.

As illustrated in FIG. 8b, in this embodiment, the user can use a finger to touch the user information on a touch screen of the mobile terminal 6 when logging into QQ and gently slide upwards to trigger the mobile terminal to transmit a first command including user information (e.g., picture 4, username 3, and user ID 5) for logging into QQ to the server. The user can touch the user information (e.g., picture 4, username 3, and user ID 5) for logging into QQ on the touch screen of the mobile terminal and slide gently upward to produce the visual effect of the user information (e.g., picture 4, username 3, and user ID 5) for logging into QQ being moved out of the mobile terminal. At the same time, the display device can display the user information (e.g., picture 4, username 3, and user ID 5) for logging into QQ, and thus providing the user a visual effect of moving information from the mobile terminal into the display device. This can further improve the visual effects of the interaction.

In this embodiment, the first command can be a synchronous animation starting instruction or another newly-added command. The second command can be an animation starting command or another newly-added command.

As such, the method illustrated in FIG. 6 can simplify the interaction process between the mobile terminal and the server, reduce manual participation by the user, and thus improving user experience. In addition, in this embodiment, the information transmitted by the mobile terminal can be displayed by the display device. This can, to certain extent, visually present the interactions between the mobile terminal and the server, making the interactions between the mobile terminal and the server more vivid.
