A remote controller comprises a shifter lever structure, a controller, and a signal emission device. The shifter lever structure comprises a base, a press key movably connected to the base, a shifter lever arranged surrounding the press key and movably connected to the base, and a sensor coupled to the press key and the shifter lever and configured to obtain moving state information about the press key and the shifter lever. A movement mode of the shifter lever is different from a movement mode of the press key. The controller is electrically coupled to the sensor. The signal emission device is electrically coupled to the controller. The controller is configured to receive the moving state information from the sensor and emit a control signal corresponding to the moving state information via the signal emission device.

Provided is an electromagnetic induction potentiometer adaptive for full-stroke detection, including a movable element configured to obtain an input for position change, a permanent magnet attached to the movable element, a magnetic induction sensor configured to sense positions of the permanent magnet and generate an initial potential signal, and an full-stroke adaptive output adjusting unit configured to collect the initial potential signal and adaptively adjust the initial potential signal to an actual potential signal corresponding to a full stroke of position changing of the movable element.

An input/output operation device (165) includes: an operation part (850); a movable unit (180) including a loosely fitted space inside, a main body supporting the operation part (802) and including a first loosely fitted surface (820) exposed in the loosely fitted space, and at least one drive magnet (401, 402); a fixed unit including a second loosely fitted surface (821) in point- or line-contact with the first loosely fitted surface of the movable unit, a holder (811) supporting the movable unit for free rotation, a base (811) including a space for accommodating at least a part of the movable unit and supporting the holder, and at least one drive coil (301, 302); a drive part to rotate the movable unit with respect to the fixed unit; and a detector to detect a position of the operation part in the fixed unit. One of the first and second loosely fitted surfaces includes an inner peripheral surface formed into a recessed portion, and another one of the first and second loosely fitted surfaces includes at least one protruded spherical surface.

A one-handed joystick for excavators allows an operator to make all necessary motions with a single hand and arm for manipulating an excavator tool. The one-handed joystick includes a rotatable cylinder bar, a rotatable ring and an industrial joystick base. The rotatable cylinder bar is grasped with a hand. The industrial base is moved front to back, or right to left. The following are preferable hand/arm motions. A downward hand curl is associated with a bucket digging motion; an upward hand curl is associated with a bucket dump; a forearm forward push is associated with a boom/stick extension; a forearm reward pull is associated with a boom/stick retraction; a left-hand movement is associated with swinging the excavator left; a right-hand movement is associated with swinging the excavator right; a clockwise hand twist is associated with a stick/boom extension; and a counter clockwise hand twist is associated with a stick/boom retraction.

A remote controller includes a fixed body equipped with pivots in a first axis and pivots in a second axis, together with an operating lever. The remote controlling further includes a main frame configured to pivot about the axes to transmit pivoting movement of the lever to a pivoting sensor. The main frame is coupled by pivots to the lever. The lever has two pairs of arms to control the pivoting of the main frame and the pivoting of the auxiliary frame. The auxiliary frame is coupled to the lever by an intermediate frame. The intermediate frame is coupled to the auxiliary frame by a swivel. The frames are located under a plane of the axes and the lever is located above the plane of the axes.

A four-axis joystick provides the ability to control four parameters in a single input device. In one embodiment, the Z-direction of control is implemented by a telescoping joystick handle, with the X- and Y-directions of control being implemented by pivoting motions of the handle in directions radial to an axis of the joystick handle, and the theta-direction of control implemented by rotation of a portion of the handle about the handle axis. The four-axis joystick may be used as an input device for audio mixing applications with the X-, Y-, and Z-dimensions of control mapped to panning of an audio source in the left-right, forward-backward, and up-down directions respectively, and the theta-dimension mapped to volume control of low frequency effects.

The present disclosure relates to an input device, including: a base part, a support, a handle mounted to the support in a pivotably movable manner, a detector for detecting the position of the handle and at least one magnet pair of one first magnet associated with the handle means and a second magnet associated with the base part, wherein the first magnet and the second magnet, at least in one position of the handle, are disposed spaced apart over an air gap (d) and opposite to each other, in order to cause a haptic feedback and/or a returning action during the operation of the handle, wherein adapting means are provided for adapting the clear distance between the first magnet and the second magnet of the magnet pair by adapting the adapting means.

Provided is a control stick capable of measuring rotation angles thereof and automatically returning to an original point after the rotational movements. The control stick includes a rotating rod rotated in a yawing direction and a pitching direction, a first spring which returns the rotating rod to an original point when the rotating rod rotates in the yawing direction, a first rotation angle measurement portion which measures a rotation angle of the rotating rod in the yawing direction and transmits the measured rotation angle to a controller of the motion simulator, a second spring which returns the rotating rod to an original point when the rotating rod rotates in the pitching direction, and a second rotation angle measurement portion which measures a rotation angle of the rotating rod in the pitching direction and transmits the measured rotation angle to the controller of the motion simulator.

A technique for a stick device improves durability or other characteristics. A stick device includes a stick rotatable about a first axis (X-axis), rotatable about a second axis (Y-axis), and pushable in a direction of a third axis (Z-axis) in response to an operation of a user, and a sensor that contactlessly detects a distance of a push on the stick or a position of the stick in the direction of the third axis (Z-axis).
