Title:
押下操作検出装置および押下操作検出方法
Document Type and Number:
Japanese Patent JP7225034
Kind Code:
B2
Abstract:
A pressing operation detection device includes a pressing operation determination unit determining whether a pressing operation has been performed based on a touch on an operation unit and a pressing amount, an increase-and-decrease frequency detection unit detecting occurrence frequency of increase and decrease of a pressing amount every predetermined period of time, and a determination controller changing content of the determination process of the pressing operation determination unit based on the occurrence frequency detected while a touch on the operation unit is not detected. When a pressing amount is detected although the operation unit is not touched, assuming that increase and decrease of the pressing amount is caused by vibration, content of the determination process is changed such that influence of the vibration is reduced so that detection of a pressing operation which brings a feeling of strangeness to the user which is caused by the vibration may be avoided.
