OPERATION DETECTION DEVICE

PROBLEM TO BE SOLVED: To provide an operation detection device which suppresses an erroneous execution unintended by an operator.SOLUTION: An operation detection device 1 includes: a detecting part 15 which detects trace operation on an operating face 100 with a finger; and a control part 17 which determines that operation on a different direction is invalid when a first condition that detected trace operation distance is longer than predetermined first distance and a second condition that a distance of operation, detected following the traced operation, in the direction different from a direction of the trace operation is shorter than a predetermined second distance are at least satisfied.SELECTED DRAWING: Figure 1 【課題】操作者が意図しない操作の実行を抑制する操作検出装置を提供する。【解決手段】操作検出装置１は、指によって操作面１００になされたなぞり操作を検出する検出部１５と、検出されたなぞり操作の距離が予め定められた第１の距離より長いとする第１の条件及びなぞり操作に続いて検出されたなぞり操作の方向と異なる方向の操作の距離が予め定められた第２の距離より短いとする第２の条件が少なくとも満たされた場合、異なる方向の操作を無効と判定する制御部１７と、を備えている。【選択図】図１
