Electronic device
View Patent ↗An electronic device 10 according to an embodiment includes: a display section 12 for displaying an operation area 40 ; a touch panel 11 disposed on a display surface side of the display section 12 ; a vibration section 13 for vibrating the touch panel 11 ; a vibration control section 33 for controlling a vibration pattern of the vibration section 13 ; and a detection section 20 for detecting whether an operation to the touch panel 11 has been made with a has been made with a finger of a user or a pen. The vibration control section 33 varies the vibration pattern of the vibration section 13 depending on whether a finger or a pen is detected by the detection section 20.
1. An electronic device comprising:
a panel touched by a user;
a vibration section configured to vibrate the panel;
a vibration control section configured to control a vibration of the vibration section; and
a detection section configured to detect between whether an operation to the panel has been made with a finger of a user or whether the operation to the panel has been made with an input means other than a finger, wherein
the vibration control section varies the vibration of the vibration section differently depending on whether the finger of the user or the input means other than the finger is detected by the detection section, and
the vibration section causes a greater vibration in the panel when the finger is detected than when the input means other than the finger is detected in order to compensate for differences in vibration propagation characteristics between the finger of the user and the input means other than the finger, so that the user feels approximately the same degree of a vibration regardless of whether the operation to the panel has been made with the finger of the user or the input means other than the finger.
2. The electronic device of claim 1 , wherein the detection section detects a pressure applied to the panel, and based on the detected pressure, detects whether the operation to the panel is made with the finger or the input means other than the finger.
3. The electronic device of claim 1 , wherein,
the panel is a panel of an electrostatic type; and
the detection section determines that the operation is made with the input means other than the finger if the value of a change in electrostatic capacitance caused by the operation to the panel is equal to or greater than a threshold value, and determines that the operation is made with the finger if the value of the change in electrostatic capacitance is less than the threshold value.
4. The electronic device of claim 1 , wherein,
the panel is a panel of an electrostatic type; and
the detection section detects an area of contact of a portion in which contact between the finger or the input means other than the finger and the panel has occurred, and based on the detected area of contact, detects whether the operation to the panel is made with the finger or the input means other than the finger.
5. The electronic device of claim 4 , wherein the detection section determines that the operation is made with the finger if the detected area of contact is equal to or greater than a threshold value, and determines that the operation is made with the input means other than the finger if the detected area of contact is less than the threshold value.
6. The electronic device of claim 1 , wherein,
the panel includes a panel of an electrostatic capacitance type and an electromagnetic-type detection substrate; and
the detection section detects the input means other than the finger based on a change in voltage of the electromagnetic-type detection substrate, and detects the finger based on a change in electrostatic capacitance of the panel of an electrostatic capacitance type.
