The method for interchanging information according to claim 1, which is characterized in that charge is levied based on the amount of request information sent or the amount of information transmitted.ħ. The method for interchanging information according to claim 1, which is characterized in that said request has arbitrary position data and viewing direction data indicating an arbitrary direction as said arbitrary position and said information is contents information possessing said image with or without voice associated with said position data and said viewing direction data, with said image being so constructed as to be displayed in frame units, and the frequency at which the final stage processing is repeated is the frequency at which the image of said contents information is updated.Ħ. The method for interchanging information according to claim 3, which is characterized in that said position data is one which is selected from (1) positioning data which is generated intermittently by satellite or radio positioning or (2) position data obtained by interpolation of the amount of movement (which is calculated from the moving speed and moving time of the receiving side) and said positioning data obtained most recently, said position data being generated while said positioning data is not generated.ĥ. The method for interchanging information according to claim 1, which is characterized in that said request has arbitrary position data and said information is contents information possessing said image with or without voice associated with said information, with said image being so constructed as to be displayed in frame units, and the frequency at which the final stage processing step is repeated is the frequency at which the image of said contents information is updated.Ĥ.
The method for interchanging information according to claim 1, which characterized in that the frequency at which the final stage processing step can be repeatedly updated is confirmed by actual measurement by said receiving side.ģ. A method for interchanging information in which a receiving side, which receives information, sends to a sending side, which keeps said information, a request for transmission of said information through a communication system, said sending side, in response to said request, sends said receiving side said information through said communication system, and said receiving side receives said information which has been sent and displays said information in the form of an image with or without voice, on the assumption that generation of said request in said receiving side is a preliminary processing step and said displaying at said receiving side is a final processing step, there is at least one intermediate processing step in at least any of said receiving side, said sending side, and said communication system, between said preliminary processing step and said final processing step, the route along which an ensuing processing step is executed by using the result of a preceding processing step constitutes a loop, and the number of times for updating processing within a unit time is a frequency, wherein said method comprises: repeatedly updating said request and said loop, and keeping the frequency of at least one step before the preceding processing step from said final stage processing step lower than a permissible frequency for which said final stage processing step has been confirmed.Ģ. As a result, power consumption is reduced and communication load is mitigated.ġ. A standard frequency stfQ which does not exceed the thus determined frequency is set, the processes along the loop are performed at the standard frequency stfQ or a lower frequency. Since the achievable frequency of repetitive updating and performing the loop varies by the combination of receiving side CL 1, communication system NT, and sending side SV 1, the achievable maximum frequency mxfQ for each loop is determined from a given table or by actual measurement.
A loop that a receiving side CL 1 sends a request signal CL 1 a carrying position data pd to a sending side SV 1 through a communication system NT, the sending side SV 1 sends back contents information corresponding thereto as a sending signal SV 1 a, and the receiving side CL 1 displays the signal is repetitively updated and performed at a high frequency by repetitively updating and sending the position data pd at a high frequency. Disclosed is a method for interchanging contents information and a system for interchanging contents information.
