Embodiment Construction

[0024] figure 1 A schematic diagram of an input panel device 1 in an inactive state according to an embodiment of the present invention is shown. Shown is an input panel device 1 having an input touch surface 3, a control unit 5, a sensor 7 for monitoring load, a touch substrate 11 for monitoring contact, a tactile feedback generating unit 9, and a device housing 13 . The tactile feedback generating unit 9 comprises a housing 9, a coil 93, a core 95 and an end stop 97 for the core. The touch panel device is fixedly positioned in the control panel of the vehicle. The core 95 is in the initial position P1 , resting on the supporting element, the end stop 97 . No current flows in the coil 93 . The core 95 is movable relative to the coil 93 along the long axis Z of the coil.

[0025] The tactile response generating unit 9 is rigidly attached to the touch input surface 3 . The connection 21 comprises a portion of the touch input surface 3 extending towards the tactile respons...

Abstract

The invention relates to a touch panel device (1) comprising a touch input surface (3), at least one sensor (7,11) that serves to monitor a contact and/or a load applied to the touch input surface (3), a tactile response generation unit (9) that is rigidly connected to the touch input surface (3), and a control unit (5) that serves to process a signal from the sensor (7,11) and control the tactileresponse generation unit (9) on the basis of the monitored contact and/or load, wherein the tactile response generation unit (9) comprises a housing (91 ), said housing comprising magnetically conducting material, an electrically conducting coil (93) arranged fixedly within the housing (91 ), and a core (95) comprising magnetically conducting material, wherein the core (95) is arranged within thecoil (93), such that the core (95) is movable along a long axis (Z) of the coil (93).

Description

technical field [0001] The present invention relates to a touch panel device comprising a touch input surface, at least one sensor for monitoring contact and / or load applied to the touch input surface, and means for providing a tactile response to a user of the touch panel device Haptic response generation unit. Background technique [0002] Touch panel devices are becoming more and more common, for example in the form of smartphones or control panels of household appliances or vehicles. Touchscreens are often used with haptic response systems. A common example of this technology is the vibration feedback provided when a button on a touchscreen is tapped. Haptics improve the user experience with touchscreens by providing simulated tactile feedback, and can be designed to react instantly, partially offsetting response delays on the screen. [0003] Patent publications EP2461233B1 and US9280205B2 respectively disclose a method and a device for providing a "click" sensation ...
