Remote operation device
A remote operation device includes a first operation acceptance portion having a rotary dial, a second operation acceptance portion provided along an outer periphery of the rotary dial and allowed to rotate separately from the rotary dial, and a control portion. When a relative position of a user's hand with respect to the first operation acceptance portion is at a covered position, the control portion switches the first operation acceptance portion and the second operation acceptance portion to a locked state and accepts an operation on the first operation acceptance portion. When the relative position of the user's hand with respect to the first operation acceptance portion is at an uncovered position, the control portion switches the first operation acceptance portion and the second operation acceptance portion to an unlocked state and accepts an operation on the second acceptance portion.
1. A remote operation device attached to an attached portion, which is a predetermined portion of a mobile body, and configured to operate a device installed to the mobile body by remote control, the remote operation device comprising:
a first operation acceptance portion provided as a mechanism to accept an operation from an outside and having a rotary disc supported in a displaceable and rotatable manner and a reactive force generation mechanism applying a force to the rotary disc in response to the operation from the outside;
a second operation acceptance portion provided as a mechanism to accept an operation from the outside and provided along an outer periphery of the rotary disc of the first operation acceptance portion and allowed to rotate separately from at least the rotary disc;
a position detection portion detecting a relative position of a user's hand with respect to the first operation acceptance portion;
and a control portion controlling the first operation acceptance portion to be a subject to accept an operation when the relative position detected by the position detection portion is at a covered position at which a percentage of the first operation acceptance portion covered by the user's hand is equal to or greater than a preliminarily determined percentage, and controlling the second operation acceptance portion to be a subject to accept an operation when the relative position is at an uncovered position at which the percentage of the first operation acceptance portion covered by the user's hand is less than the predetermined percentage.
2. The remote operation device according to claim 1 , further comprising:
a palm rest portion extending from the attached portion so as to cover the first operation acceptance portion and provided with a touch panel at a position corresponding to a top surface of the first operation acceptance portion,
wherein the position detection portion detects the relative position of the user's hand with respect to the first operation acceptance portion on the basis of a position and an area of the touch panel where the user's hand is in contact.
3. The remote operation device according to claim 1 , further comprising:
a drive switching portion that switches the second operation acceptance portion between a locked state in which the second operation acceptance portion is locked with the first operation acceptance portion so as to rotate integrally with the first operation acceptance portion and an unlocked state in which the second operation acceptance portion is released from the locked state so as to rotate separately from the first operation acceptance portion,
wherein the control portion controls the drive switching portion to switch the second operation acceptance portion to the locked state when the relative position detected by the position detection portion is at the covered position, and controls the drive switching portion to switch the second operation acceptance portion to the unlocked state when the relative position is at the uncovered position.
