PROBLEM TO BE SOLVED: To provide a terminal device and an alarming method that can recognize that another ship is approaching without a dedicated device such as an AIS.SOLUTION: A terminal device includes: a self-position acquisition unit for acquiring its positional information; a display unit for displaying an image; a communication unit for communicating with an information distribution device; and an image display control unit that determines whether or not a ship has invaded an alarm notification zone based on the self-position on the basis of the position of the ship included in ship information obtained by the communication unit, obtains a relative direction and speed to itself using a travel direction and travel speed of the ship based on the ship information regarding the ship that has invaded the alarm notification zone, and then outputs display contents corresponding to a result of determination of whether to output an alarm according to a prescribed determination rule to the display unit.SELECTED DRAWING: Figure 1
【課題】AIS等の専用装置を備えることなく、他船舶が近づいていることを認識することが可能な端末装置、警報方法を提供する。【解決手段】自己の位置情報を取得する自己位置取得部と、画像を表示する表示部と、情報配信装置と通信をする通信部と、前記通信部が取得した船舶情報に含まれる前記船舶の位置に基づいて前記船舶が前記自己の位置を基準とした警報通知ゾーンに侵入したか否かが判定され、前記警報通知ゾーンに侵入した前記船舶について、前記船舶情報に基づく前記船舶の進行方向、移動速度を用いて自己との相対的な方向および速度を得た後、所定の判定ルールに従って警報を出力するか否かの判定が行なわれた結果に応じた表示内容を前記表示部に出力する画像表示制御部とを有する。【選択図】図1
