The disclosure relates to a device for blocking display and/or operating contexts comprising at least one operating apparatus for detecting user interactions, and an evaluation apparatus, configured to determine a current involvement value at least on the basis of the detected user interactions. The evaluation apparatus is configured to compare the current involvement value with at least one interruption threshold value and to establish a blocking state if the current involvement value reaches the interruption threshold value. The evaluation apparatus blocks or at least restricts at least one operating context of the at least one operating apparatus. The current involvement value is increased for each detected haptic user interaction, insofar as the current involvement value has not reached or exceeded the at least one interruption threshold value and the evaluation apparatus is configured to lower, continuously or in increments of time, the current involvement value by a recovery value.

A lever switch includes: an operation lever including an operation portion to which an operation load is to be applied, and configured to swing around a rotation axis; a first drive lever driven by the operation lever and configured to swing around a first fulcrum to drive a first switch in response to the operation lever being operated around the rotation axis in a first direction; and a second drive lever driven by the operation lever and configured to swing around a second fulcrum to drive a second switch in response to the operation lever being operated in a second direction opposite to the first direction. When projected onto a plane orthogonal to the rotation axis, the first and second fulcrum are disposed on the same side with respect to a virtual straight line passing through the operation portion and the rotation axis, and separated from the virtual straight line.

The present invention provides a multi-function switch unit (10) comprising a plurality of switch units (300, 300a, 500)) disposed spaced apart from each other in a housing (100), wherein each of the plurality of switch units is at least partially disposed on a single substrate (200).

An image processing system and method is provided for controlling an amount of perceptual three-dimensional elements for a display. The method includes: receiving an input image; receiving user information concerning a user; adjusting an amount of perceptual three-dimensional elements within the input image to obtain an adjusted input image based on depth information of the input image and the user information; and displaying the input image as adjusted on a display. The user information may include user profile information and/or a predetermined perceptual 3D control input. The image processing system and method may be used to tune the amount of perceptual three-dimensional elements within the input image according to the user.
