INFORMATION PROCESSOR, TERMINAL, METHOD FOR PROCESSING INFORMATION, METHOD FOR WARNING, AND WARNING SYSTEM

To provide an information processor, a terminal, a method for processing information, a method for warning, and a warning system which can issue a warning about a mobile body.SOLUTION: In a warning system 1, a server 20 includes: a processing unit for determining a prediction time when a positioning terminal 10 intrudes into a specific area on the basis of the position, speed, and the travelling direction of the positioning terminal 10, and the position of the specific area and determining whether or not to cause the positioning terminal 10 to issue a warning on the basis of the prediction time; and a communication unit for sending, to the positioning terminal 10, a signal for causing the positioning terminal 10 to issue the warning when it is determined that the terminal 10 is to issue the warning.SELECTED DRAWING: Figure 1 【課題】移動体について適切に警報を行う情報処理装置、端末、情報処理方法、警報方法及び警報システムを提供する。【解決手段】警報システム１において、サーバ２０は、測位端末１０の位置、速度及び進行方向と、特定のエリアの位置と、に基づいて、端末１０が特定のエリアに侵入する予測時間を決定し、予測時間に基づいて、警報を端末１０に発出させるか否かを決定する処理部と、警報を端末１０に発出させると決定された場合、警報を端末１０に発出させるための信号を、測位端末１０に送信する通信部と、を備える。【選択図】図１
