  • the input condition itself can be used in the Computer device or the input device 800 and / or the operating element 802 itself can be deposited and stored. In this way, a user receives a predeterminable and programmable haptic feedback via an input.
  • An input from the user is detected via a sensor device 5, which can detect both a pivoting movement 827 and a linear movement 826.
  • the sensor device 5 also detects the movement parameters, which here include the direction of rotation, the speed and the acceleration.

  • a haptic mode describes a possible embodiment of the method for controlling the input element 802 here.
  • the mouse wheel 804 works depending on the direction 813 as a function of the movement 809 in the movement area 812. If the input element 802 embodied here as a mouse wheel 803 is rotated to the left, the braking device 1 generates a rotation angle-dependent grid 810 with stop points 811, which the user here as perceives surmountable resistance when turning. If the mouse wheel 803 is moved to the right, there is freewheeling 829 in which the mouse wheel 803 can be freely rotated. This enables the user to receive direct feedback about his input.
  • FIG. 8 Another haptic mode of the method is shown in FIG. After a linear movement 826 of the mouse wheel 803 the mobility of the input element 802 is completely blocked by the agnetorheological braking device 1. This effectively prevents unwanted parallel incorrect entries by the user. The force in the attachment point 811 is so great that a user cannot overcome it.

  • the range of motion 812 of an input element 802 can be variable and in particular adjustable as a function of the haptic mode. In this way, it is advantageously possible to adapt the mobility and haptic feedback to the individual needs of a user or as a function of a use or a program.

  • the braking device is controlled with a current and / or voltage signal with a frequency 824 of 100 Hz.
  • the sign of the frequency signal varies.
  • a user receives haptic feedback in the form of vibration 825.
  • a portion of the positive and negative current flow is distributed asymmetrically 823. This leads to a change and at the same time to an advantageous perception of the vibration 825 by the user.
  • Due to the high frequency an audible tone 821 is also generated by the braking device 1.
  • This haptic mode is advantageously suitable for sending an acoustic warning signal 822 to the user.
  • the haptic mode shown here in FIG. 9 is based on a control of the braking device 1 with a random current signal 820. As a result, for example, the wear of a bearing or, for example, sand in a transmission can be shown for a user.
  • a possible user interface 830 is shown, by means of which the individual haptic modes can be changed, combined to form a profile 819.
  • the user interface 830 can have several setting levels 828.
  • a user can set the control of the braking device 1 as a function of the direction 813 and the speed 814 and acceleration 814.
  • the input conditions for skipping 815 and pressing and blocking 816 can also be set.
  • Profiles can be saved individually. It is also possible here to use preset profiles 818, for example from other users, in particular in a program-specific manner.

Abstract

Procédé de fonctionnement d'un appareil d'entrée (800) et appareil d'entrée. Un élément d'entrée (802) de l'appareil d'entrée (800) est actionné manuellement pour la réalisation d'une entrée. Une mobilité de l'élément d'entrée (802) peut être retardée, fixée, bloquée et libérée de manière ciblée au moyen d'un dispositif de freinage magnétorhéologique commandable (1). La mobilité de l'élément d'entrée (802) est adaptée de manière ciblée en fonction d'au moins une condition d'entrée enregistrée dans un dispositif informatique. La condition d'entrée peut notamment comporter un paramètre du mouvement de l'élément d'entrée qui comporte quant à lui au moins la direction, la vitesse et/ou l'accélération d'un mouvement (809).
