TECHNICAL FIELD
[001] The present subject matter described herein, in general, relates to a method for
establishing wireless communication between two devices, and more particularly the method for establishing a stateless communication between the two devices.
BACKGROUND
[002] Traditionally, mobile devices include short-range radio interfaces that are
adapted to enable communication with communication devices using communication protocols. The examples of the mobile devices and the communication devices may comprise a multi-touch table, a kiosk, a mobile phone, a tablet or the like. For example, the commonly used communication protocol for short-range wireless communications may include Bluetooth® and Near Field Communication (NFC).
[003] In order to facilitate the communication, the communication protocols used
today requires explicit pairing between the mobile devices and the communication devices. The process of pairing involves the two devices to know each other by way of exchanging security credentials. Therefore, the existing methods require the pairing between two devices which once established can be used for multiple sessions and hence is not stateless in nature.
[004] In order to establish stateless communication, an accelerometer based peer
identification and data transfer methods is being used in the existing art. However, the existing accelerometer based peer identification methods requires a physical trigger and accelerometer data from the two communication devices in order to establish the stateless communication.

DETAILED DESCRIPTION
[0022] Systems and methods for establishing a communication between an electronic
device and a mobile device through a server are described. In one aspect, the communication may be established by at least one of Radio-frequency identification (RFID™), near field communication (NFC), Bluetooth™, Wi-Fi™ and a cellular data network. In one aspect, the electronic device may be at least one of a multi-touch table, a kiosk and an automatic teller machine (ATM). In one aspect, the mobile device may be at least one of a Smartphone, a personal digital assistant (PDA), a laptop and a palmtop. In one aspect, the communication between the electronic device and the mobile device may be a stateless communication and hence may not require explicit pairing between the electronic device and the mobile device.
[0023] In order to establish the communication between the electronic device and the
mobile device, a user of the mobile device may initiate an application installed on the mobile device. The application on initiation may enable the mobile device to communicate with the server. As soon as the user places the mobile device on a display unit of the electronic device, the mobile device may be adapted to stabilize accelerometer data associated with the mobile device. Upon placing the mobile device on the electronic device, the electronic device may detect an object placed on its display unit and further differentiates it from regular touch input. On detecting the object as the mobile device, the electronic device may be further adapted to display a color image on a display unit of the electronic device. In one aspect, the electronic device may display a sequence of colors at different time instants. The sequence of colors and the timestamp associated with each color of the sequence of colors may be transmitted to the server by the mobile device and the electronic device. In one aspect, the sequence of colors to be displayed on the display unit may be randomly chosen or may be preconfigured in the electronic device.
[0024] In one implementation, the mobile device may be detected by using at least
one of a blob detection mechanism and flash of the mobile device. Further on detecting the mobile device on the display unit, the electronic device may transmit a first trigger signal to the server. In one aspect, the first trigger signal may comprise an identification number of the electronic device, a time stamp of the first trigger signal and location information of the electronic device.

[0025] Based on the stabilization of the accelerometer data and the color image
displayed, the mobile device may be further adapted to capture RGB data associated to the color image displayed on the display unit. In one aspect, the RGB data may be captured by an image capturing unit such as camera embedded with the mobile device. Upon capturing the RGB data, the mobile device may further transmit a second trigger signal comprising the RGB data to the server. In one aspect, the second trigger signal may further comprise an identification number of the mobile device, a time stamp of the second trigger signal and location information of the mobile device.
[0026] After receiving the first trigger signal and the second trigger signal, the server
may match the first trigger signal with the second trigger signal in order to validate an intended communication between the electronic device and the mobile device. After matching the first trigger signal with the second trigger signal, the server may be further adapted to generate a first identification token for the electronic device and a second identification token for the mobile device. In order to facilitate the communication between the electronic device and the mobile device, the server may transmit the first identification token to the electronic device and the second identification token to the mobile device. In one aspect, the first identification token may comprise the identification number of the mobile device whereas the second identification token may comprise the identification number of the electronic device.
[0027] The electronic device and the mobile device may be then adapted to receive the
first identification token and the second identification token respectively from the server in order to establish the communication amongst them. Upon receiving the first identification token and the second identification token, the electronic device and the mobile device may establish the communication that may be used for one time data exchange. In one aspect, the stateless communication may be established as long as the mobile device is placed on the electronic device.
[0028] While aspects of described system and method for establishing the
communication between the electronic device and the mobile device through the server may be implemented in any number of different computing systems, environments, and/or configurations, the embodiments are described in the context of the following exemplary system.

device 104 (b) may be explained in detail in Figures 3, Figure 4 (a), Figure 4 (b) and Figure 4 (c) explained below.
[0051] Referring to Figure 3, a detailed working of components involved for
establishing the communication between the electronic device 104 (a) and the mobile device 104 (b) through the server 102 is illustrated, in accordance with an embodiment of the present subject matter. In one implementation, the communication may be a one-time stateless communication established by at least one of Radio-frequency identification (RFID™), near field communication (NFC), Bluetooth™, Wi-Fi™ and a cellular data network. In one aspect, the electronic device 104 (a) may be at least one of a multi-touch table, a kiosk and an automatic teller machine (ATM). In one aspect, the mobile device 104 (b) may be at least one of a Smartphone, a personal digital assistant (PDA), a laptop and a palmtop.
[0052] In an exemplary embodiment of the invention, a user of the mobile device 104
(b), may initiate an application installed on the mobile device 104 (b). As soon as the user places the mobile device 104 (b) on a display unit of the electronic device 104 (a), the stabilization module 412 may be configured to stabilize accelerometer data of the mobile device 104 (b). In one aspect, the communication may be initiated when the mobile device 104 (b) is placed on the electronic device 104 (a) causing the accelerometer data of the mobile device 104 (b) to become stable along at least one axis.
[0053] On the other hand, the detection module 312 may be configured to detect an
object placed on the display unit. The detection module 312 may further be configured to differentiate the object from regular touch input. In one aspect, the detection module 312 may detect the object as the mobile device 104 (b) by using at least one of a blob detection mechanism and flash of the mobile device 104 (b). In one aspect, the blob detection

mechanism may enable the electronic device 104 (a) to detect the mobile device 104 (b) that has been kept on the display unit as an object that is distinct than the normal touch input received on the electronic device 104 (a). The blob detection mechanism may further enable the electronic device 104 (a) to display a color image on the display unit of the electronic device 104 (a). In another aspect, when the electronic device 104 (a) is unable to detect the object as the mobile device 104 (b) and does not display the color image, the mobile device 104 (b) after a predefined time out may employ the flash to generate the blob on the display unit of the electronic device 104 (a). The blob will be detected by the electronic device 104 (a). Further a start time may be recorded when the flash is turned on and a stop time can be recorded when the flash is turned off. In one aspect, the start time and the stop time may be communicated to the server 102 for synchronization and detection of the peer device for communication.
[0054] Upon detecting the mobile device 104 (b), the display module 314 may be

The image generation module may further be configured to generate the color image. The color image may be associated to the mobile device 104 (b). In another aspect, the color image may be generated by the server 102. In order to generate the color image, the server 102 may have a preconfigured list of a RGB Hexadecimal (Hex) codes that are configured as a part of the server 102. In one aspect, the server 102 may also be adapted to randomly generate the RGB Hex Code. In one embodiment, the electronic device 104 (a) may display a sequence of colors at different time instants. The sequence of colors and the timestamp associated with each color of the sequence of colors may be transmitted to the server 102 by the mobile device 104 (b) and the electronic device 104 (a). In one aspect, the sequence of colors to be displayed on the display unit may be randomly chosen or may be preconfigured in the electronic device 104(a).
[0055] After displaying the color image, the transmitting module 316 may further
configured to transmit a first trigger signal to the server 102. In one aspect the first trigger signal may comprise color data associated to the color image, an identification number of the electronic device 104 (a), a time stamp of the second trigger signal and location information of the electronic device 104 (a). The color data associated to the color image may comprise a

representation of additive color mixing having a value associated to three different colors i.e. Red, Green and Blue.
[0056] Based on the stabilization of the accelerometer data and the color image
displayed on the electronic device 104 (a), the sensing module 414 may be configured to capture RGB data associated with the color image generated by the electronic device 104 (a). The RGB data may comprise the representation of additive color mixing having the value associated to three different colors i.e. Red, Green and Blue. In one aspect, the RGB data may be captured by an image capturing unit such as camera embedded with the mobile device 104 (b). After capturing the RGB data, the transmission module 416 may be configured to transmit a second trigger signal comprising the RGB data to the server 102. In one aspect, the second trigger signal may further comprise an identification number of the mobile device 104 (b), a time stamp of the second trigger signal and location information of the mobile device 104(b).
[0057] The first trigger signal and the second trigger signal may then be received by
