  • Writing instruments typically ballpoint pens
  • the front housing portion which includes and holds the writing tip of the face consists of a translucent material.
  • a light source typically a light emitting diode mounted, which is powered by also arranged in the writing instrument batteries with power. The light source radiates through the translucent front part and thus illuminates the writing surface area around the writing tip.
  • Such pens look interesting and you can write well in otherwise dark places.
  • the illuminated area is too large and its contours too unclear.
  • WO 2003 096 321 A1 shows a writing instrument to be guided by hand on a writing surface, in which a light source is attached to the area around the writing tip as well as a small camera, which photographs the illuminated writing surface area in rapid succession.
  • An arithmetic unit mounted in the writing instrument concludes by image analysis on the movement of the writing instrument and thus on the driven lettering.
  • the relevant information is in the writing instrument stored and can be transferred to other data processing equipment.
  • An advantage of the method and the writing instrument is that with powerful software so that writing can be taken from almost any surface.
  • the disadvantages are the high costs and the bulky design of the writing instrument.
  • EP 1 416 740 A2 shows a related hand-held scanning device, which also has a conventional writing tip, wherein a portion of the writing surface which is spaced from the writing tip is illuminated with a laser beam deflected in an oscillating manner in its direction.
  • the images on the writing surface are scanned by a camera.
  • image processing By means of image processing, in turn, the movement of the writing tip can be inferred.

Except that the parts for the writing function and the laser pointer function are arranged in a common housing, these two functions have nothing to do with each other.
  • JP 2170193 A describes a method according to which an infrared light spot is generated on a projection surface by means of an infrared light source, the position of this light spot is detected by an infrared camera and the relevant point is controlled by a computer system via the one it controls Projector is indicated by a visible marker.

  • the lateral surface of the pin 1 is surrounded by a, the function of a housing engaging sleeve 4 and held.
  • the sleeve 4 has approximately the shape of a slender pipe section. At least at the writing tip of the pen, the sleeve 4 is open, so that the writing tip can be brought into contact with the writing surface.
  • a light-emitting diode 5 and a battery 6 which supplies them with electrical energy are attached.
  • An optical fiber 3 extends in the sleeve next to the pin 1 of the light emitting diode 5 to the writing tip 1.1 of the pin. From the light emitting diode 5 is coupled into one end of the optical fiber. At the other, write tip side end 3.1 of the optical fiber emerges light again.

  • the tracking of the light spot is particularly simple if the writing surface (2) is a detector film which is photosensitive, measures the position of the light spot and forwards the measurement result to a computer system in which the information can be stored and processed. Instead of one complete image in each case, only a small number of adjoining XY coordinate pairs, ideally only one XY coordinate pair each, are to be transmitted and processed as temporally successive measurement results.
  • the writing surface is also used as an optical reproduction device for a computer system, that is, either as a screen or as a projection screen illuminated by a projector, it can also be dispensed with that the writing instrument itself emits color substance. Instead, writing on the writing surface can simply be displayed as an image output from the computer system.
  • the writing surface is an organic semiconductor based optical position detector for an incident light spot.
  • a first, planar electrode is arranged on a substrate made of glass or a flexible organic material, which has a significantly high ohmic resistance within its circuit. This is followed by a layer of organic photoactive materials 1 within which a donor and an acceptor layer abut each other. This layer is again followed by a planar electrode, which, however, has a low ohmic resistance. At its edge, the photoactive materials with a plurality of point or line-like, spaced apart terminal electrodes are provided.
  • a current flows through the individual connection electrodes. From the size of the current in the individual terminal electrodes can be closed to their proximity to the point of impact of the light beam and thus the impact point of the light beam can be calculated by a kind of triangulation.
  • a first, poorly conductive planar electrode is applied to a substrate, then a photoactive organic semiconductor layer and then again a poorly conductive electrode.
  • the poorly conductive, planar electrodes arranged on both sides of the photoactive organic semiconductor layer can be electrically connected to an external circuit by means of two opposing connecting parts extending over a whole electrode side.
  • the connecting line between two connection parts of an electrode is normal to the connecting line between the two connection parts of the second electrode.
  • the optical position detector forming the writing surface is a planar optical waveguide in which photoluminescent particles are integrated and which has on one side a plurality of distributed, small-area photoelectric sensors which are able to extract light from the waveguide mode in the optical waveguide and to detect, so that in dependence on the intensity of the light coupled out at the respective location, an electrical signal is generated.
  • the photoluminescent particles for example, these are dye molecules or semiconductor nanoparticles
  • external light is converted into scattered light with a longer wavelength.
  • This light is largely coupled into the waveguide and spreads out (with reflection at the boundary layers). Since the light propagates in the waveguide and the light guide in the waveguide is subject to losses, the light intensity in the waveguide decreases with the distance from the emission source of the light, ie the point of impact of the outer light beam and thus the point at which the luminescence takes place also the electrical signal generated at the respective sensors.
  • a plurality of sensors are arranged at a distance from one another. From the ratio of the measured signal strengths at the individual sensors, the mathematical methods that can be automated by data technology are used to deduce the impact position of the light beam that causes the luminescence on the surface.
  • pin 1 and sleeve 4 are designed as in the example shown by the user detachable components, so this opens the possibility to work with different pins according to the invention.
  • the transmitted and to be detected light can be frequency-modulated and from the measurement result can be filtered after the respective modulation.
  • the disturbing effect of background light can be suppressed and you can " with very low luminous intensity of the LED find the Aus GmbH.
  • the color substance emitted by the writing instrument and the light to be detected should be adjusted to such an extent that the light is not absorbed too much by the coloring matter.
  • the light emission can be switched on or off either by pressing a button or pressing a switch and / or it can be turned on by a pressure sensor when placing the writing tip 1.1 on a writing surface and off by lifting the writing surface.
  • a conventional light-emitting diode or a laser diode can be used. From the laser diode is advantageous that the emitted light is within an extremely narrow spectral range, while having a very high intensity and is easy to focus. Using a conventional light-emitting diode has the advantages of lower costs and the possibility of lower energy consumption.
  • the light guiding device does not necessarily need to be an optical fiber 3. It is also possible to guide the light through a tube, which is provided at least at the corners, but better on the entire inner surface with reflectors for the light spectrum of interest.
