In general, those who are right in front of each other can share actual world events that are generated in the same working space. For example, when an audio or a light of a wave form pattern is generated, by recognizing such an actual world event, both communication apparatuses share the actual world event. Also, a shock wave generated when one communication apparatus is hit with the other is shared by both. One of the communication partners searches a network for a communication partner who is right in front with the actual world event as a clue. Thus, it is possible to perform data communications with a communication partner whose location in the actual world is clear, such as being right in front, but whose identification information in the communication medium is unknown.

The invention relates to a two-dimensional ocean current Lagrangian coherent structure analytical algorithm. The algorithm is based on a Cauchy-Green right strain tensor, wherein the tensor is obtained in a way that a gradient obtained after particles move for a period of time in a flow field is calculated. Particle movement uses a Runge-Kutta 4 order integration method, and cubic interpolation is adopted for the flow field. In order to improve calculation accuracy, four neighbor points are added on each grid point to calculate the gradient by using a finite difference. The Cauchy-Green right strain tensor is provided with two real eigenvalues, wherein the local maximum value of the large eigenvalue and the local minimum value of the small eigenvalue are seed points of an LCS (Lagrangian Coherent Structure), and the Runge-Kutta 4 order integration is carried out in a non-corresponding characteristic vector field forwards and backwards to obtain a Lagrangian coherent structure. During integration, the direction discontinuity of a character vector is considered. The direction is always kept consistent with the direction of a previous point, and inversion is carried out if the direction differs more than 90 degrees. After one LCS is generated, the LCS seed points in a certain width range of the LCS are set to be ineffective, and an interval between the LCSs is controlled. The Lagrangian coherent structure is an important flow field topological structure, can be effectively applied to the range of ocean current, season-year changes and main flow and branch flow analysis.
