(canceled) ### Claim 19 A method for pairing two devices, one of which is a first device, the other is a second device, wherein the method is implemented at the first device, comprising: generating a tracing pattern to be displayed on either of one or both of the first and second devices, by taking into account the display characteristics of both first and second devices; generating a pair of indicators for alignment references to be displayed on each of the first and second devices, said indicators providing a relative position of both first and second devices as well as a direction for a swipe gesture; sending whole or a part of the tracing pattern for displaying the tracing pattern on the second device if any and the indicator to the second device; displaying the corresponding tracing pattern and the indicator on the first device; receiving information indicating the result of tracing on the second device; and accepting pairing the two devices according to the information. ### Claim 20 (depends on 19) The method according to claim 19, wherein tracing of the tracing pattern is started in front of the tracing pattern utilizing the pair of indicators so as to swipe the second device in the right position. ### Claim 21 (depends on 19) The method according to claim 19, wherein the accepting comprising: comparing the information with the tracing pattern; determining if the information satisfies a condition; if yes, accepting pairing the two devices. ### Claim 22 (depends on 19) The method of the claim 19, wherein the pairing is requested by the second device or by the first device itself, or triggered by a particular event. ### Claim 23 (depends on 19) The method of claim 19, wherein the condition is relating to time and trace, wherein the time for swiping is calculated on the basis of output and input points of swipe. ### Claim 24 (depends on 19) The method of claim 19, wherein the first device could be paired not only with one second device but also with a plurality of second devices simultaneously. ### Claim 25 A device for pairing two devices, one of which is a first device, the other is a second device, comprising a processor configured to implement: generating a tracing pattern to be displayed on either of one or both of the first and second devices, by taking into account the display characteristics of both first and second devices; generating a pair of indicators for alignment references to be displayed on each of the first and second devices, said indicators providing a relative position of both first and second devices as well as a direction for a swipe gesture; sending whole or a part of the tracing pattern for displaying the tracing pattern on the second device if any and the indicator to the second device; displaying the corresponding tracing pattern and the indicator on the first device; receiving information indicating the result of tracing on the second device; accepting pairing the two devices according to the information. ### Claim 26 (depends on 25) The device of the claim 25, wherein tracing of the tracing pattern is started in front of the tracing pattern utilizing the pair of indicators so as to swipe the second device in the right position. ### Claim 27 (depends on 25) The device of the claim 25, wherein the accepting comprising: comparing the information with the tracing pattern; determining if the information satisfies a condition; if yes, accepting pairing the two devices. ### Claim 28 (depends on 25) The device of claim 25, wherein the pairing is requested by the second device or by the first device itself, or triggered by a particular event. ### Claim 29 (depends on 25) The device of claim 25, wherein the condition is relating to time and trace, wherein the time for swiping is calculated on the basis of output and input points of swipe. ### Claim 30 (depends on 25) The device of claim 25, wherein the first device could be paired not only with one second device but also with a plurality of second devices simultaneously. ### Claim 31 A second device to be paired with a first device, comprising a processor configured to implement: receiving whole or a part of a tracing pattern taking into account the display characteristics of both first and second devices and an alignment reference from the first device if any providing a relative position of both first and second devices as well as a direction for a swipe gesture; displaying the received tracing pattern and the alignment reference on the second devices; detecting the tracing on the screen of the second device; sending information indicating the result of tracing on the second device to the first device; waiting until pairing is accepted by the first device according to the information. ### Claim 32 (depends on 31) The second device of claim 31 further including displaying one of a pair of indicator on the second devices for alignment references. ### Claim 33 (depends on 19) Computer program downloadable from a communication network, recorded on a non-transitory medium readable by computer, and executable by a processor, comprising program code instructions for implementing a method according to claim 19. ### Claim 34 (depends on 19) Non-transitory computer-readable medium comprising a computer program recorded thereon and capable of being run by a processor, including program code instructions for implementing a method according to claim 19.
