Summary:To enhance accuracy in detecting rotating and sweeping motions by a driver in a cabin.SOLUTION: A processor receives a dataset indicative of hand positions of a driver in a cabin (STEP 11). The processor identifies a centroid position of a hand movement trajectory (STEP 12). The processor computes a ratio of a longest distance and a shortest distance from the centroid position to the movement trajectory (STEP 13). When a value of the computed ratio is equal to or greater than a threshold, the processor determines that the driver has rotated his/her hand (STEP 15).SELECTED DRAWING: Figure 4 【課題】車室内の乗員による回転動作と払い動作の検出精度を高める。【解決手段】プロセッサは、車室内の乗員の手の位置を示すデータセットを受け付ける（ＳＴＥＰ１１）。プロセッサは、手の移動軌跡の重心位置を特定する（ＳＴＥＰ１２）。プロセッサは、重心位置から前記移動軌跡までの最短距離と最長距離の比を算出する（ＳＴＥＰ１３）。プロセッサは、算出された比の値が閾値以上である場合に、乗員が手で回転動作を行なったと判別する（ＳＴＥＰ１５）。【選択図】図４
