Title: PRESSING OPERATION DETECTION DEVICE AND PRESSING OPERATION DETECTION METHOD
Abstract: [0001]    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.

Claims: number: 1
text: A pressing operation detection device including a touch detection unit configured for detecting a touch on an operation unit by a user and a pressing amount detection unit configured for detecting a pressing amount of pressing performed by the user on the operation unit, the pressing operation detection device further comprising:
number: 2
text: The pressing operation detection device according to Claim 1, wherein the determination controller is configured to determine whether the occurrence frequency of increase and decrease of a pressing amount detected by the increase-and-decrease frequency detection unit is larger than a frequency threshold value every predetermined period of time in a state in which the touch detection unit does not detect a touch on the operation unit, and to change the pressing amount threshold value used for the determination performed by the pressing operation determination unit in accordance with a result of the determination.
number: 3
text: The pressing operation detection device according to Claim 2, wherein the determination controller is configured to change the pressing amount threshold value set in the pressing operation determination unit to a value larger than a current value when the occurrence frequency of increase and decrease of a pressing amount detected by the increase-and-decrease frequency detection unit is larger than the frequency threshold value and to change the pressing amount threshold value set in the pressing operation determination unit to a value smaller than the current value when the occurrence frequency of increase and decrease of the pressing amount detected by the increase-and-decrease detection unit is not larger than the frequency threshold value.
number: 4
text: The pressing operation detection device according to Claim 2 or Claim 3, wherein the determination controller is configured to change content of the determination process performed by the pressing operation determination unit such that a determination as to whether a continuous time in which the pressing amount detected by the pressing amount detection unit reaches the pressing amount threshold value reaches a predetermined length is made instead of the determination as to whether the pressing amount detected by the pressing amount detection unit reaches the pressing amount threshold value, when the pressing amount threshold value set in the pressing operation determination unit is equal to or larger than a predetermined value.
number: 5
text: The pressing operation detection device according to Claim 2 or Claim 3, wherein the determination controller is configured to perform control such that the pressing operation determination unit does not perform the determination process when the pressing amount threshold value set in the pressing operation determination unit is equal to or larger than a predetermined value.
number: 6
text: The pressing operation detection device according to Claim 4, wherein the determination controller is configured to perform control such that the pressing operation determination unit does not perform the determination process when the pressing amount threshold value set in the pressing operation determination unit is equal to or larger than a second predetermined value which is larger than the predetermined value.
number: 7
text: A pressing operation detection method employed in a pressing operation detection device which detects a touch on an operation unit performed by a user and a pressing amount of pressing performed by the user on the operation unit, the pressing operation detection method comprising:
