Definitions

  • the touchpad in particular is characterized by annoying impairments caused by the hand of the user, the capacitive effect of which is often noticeably superimposed on the finger and can thus lead to disruptive changes to the cursor control.
  • the invention has for its object to provide a technical teaching with which these problems can be avoided. This object is achieved by an input or control device for devices and by a method for generating control signals for devices according to one of the independent claims. Advantageous further developments of the present invention are to be protected by corresponding subclaims.
  • the invention is based on the principle of determining changes in position by comparing pictorial features or features derived therefrom. This principle enables a significantly higher resolving power to be achieved in the control.
  • the invention is explained below on the basis of preferred exemplary embodiments and with the aid of the figures.
  • FIG. 1 shows a device according to the invention with two image data shifted relative to one another, which are detected by the sensor elements of the device.
  • FIG. 2 shows in a schematic manner the basic structure of a device according to the invention and the functional connection of its components.
  • the device comprises means for detecting changes in position of a finger of a system user or of a pointing instrument guided by the latter.
  • these means in the present invention - as shown in FIG. 1 - comprise a flat arrangement (SA) of suitable sensors (SE), with the aid of which pictorial features of the surface of the finger or the pointing instrument are detected and one Data processing device (DVE) for determining changes in position by comparing these pictorial features or features derived therefrom at different times.
  • SA flat arrangement
  • SE suitable sensors
  • DVE Data processing device
  • Changes in position can best be represented for the purposes of information processing in connection with the present invention in the form of so-called motion vectors, which are also called displacement vectors.
  • motion vectors which are also called displacement vectors.
  • Such means will normally be simple digital circuits, which - possibly supplemented by analog circuits and by A / D or D / A converters - represent circuits for level adjustment or driver circuits in the simplest case, but also more complicated processing steps - e.g. a speed-dependent enlargement, etc. - with the help of processors.
  • a further embodiment of the invention is particularly suitable for controlling some more complex processes, such as the remote-controlled operation of manipulators, in which changes in the rotational position (DW) are also detected and used to generate input or control signals.
  • DW rotational position
  • a particularly advantageous implementation of the invention is possible with the aid of a fingerprint sensor. In many devices, this is often available anyway for the identification or authentication of the authorized user. A local resolution of 0.05 mm can easily be achieved.
  • the position data can be easily determined by simply correlating the two-dimensional image data of the fingerprint of the finder with a stored finger. Instead of the image itself, extracted image features (edges, corners, etc.) can also be used.

Abstract

Appareils dotés d'un capteur intégré d'empreintes digitales, dans lesquels ledit capteur peut être utilisé pour déterminer la position relative d'un doigt par comparaison des caractéristiques obtenues avec des caractéristiques d'une empreinte de référence. Cela est possible grâce à une résolution locale élevée. Les modifications de position peuvent être converties en signaux d'introduction de données ou de commande pour des appareils.
