Definitions

  • the present invention relates to a device for identifying and marking locations in a surface.
  • the surface is preferably a projection surface for an image to be projected or an image sequence to be projected (e.g. a film screen).
  • the images or the image sequence can be recorded by means of a digital camera and fed into a computer for reproduction by means of a suitable projector, and can also be images or image sequences which are created directly in a computer (as a still image or as a moving image) and then onto the Area to be projected.
  • laser pens in which a viewer or a speaker directs a visible, continuous light beam onto the projection surface, which is visible there as a light spot.
  • the present invention is therefore based on the object of creating a possibility by which the viewers are able to mark points of the images in a controlled manner during the display of the images or image sequences, this marking or identification being intended to be accessible to an evaluation .
  • the invention teaches a device for identifying and marking locations in a surface, with a control unit, which is connected to a manually operable signal transmitter arrangement, and with a converter, which is a function of one output by the control unit Control signal generates a directed electromagnetic beam, the control unit being connected to a receiver in order to receive an externally generated release signal, and the control unit is set up to transmit the control signal for the
  • the manually operable signal transmitter arrangement is preferably a switch arrangement or a single or multi-axis arrangement
  • the control unit being set up to generate a switch or the joystick. Evaluate and take into account the switching, direction or path signal when generating the control signal for the converter. This enables the viewer to easily mark objects or areas in the images. These markings by means of the (light) rays can be detected by suitable sensors or scanners oriented to the (projection) surface and evaluated with appropriate hardware and / or software precautions and taken into account, for example, in the representation of subsequent images. If information about the actuation of the joystick is also impressed on the respective beam in addition to its identification by the control unit, this information can also be used, for example, to shift the marked objects in the respective direction or the like when displaying subsequent images. Perform operations with the respective object depicted on the projection surface.
  • the converter preferably has a laser diode or a for generating a directed electromagnetic beam
  • the receiver for the externally generated release signal has a direction-dependent reception sensitivity and is in a spatially defined relationship with the transducer for generating a directed electromagnetic beam in such a way that the emission of a directed electromagnetic beam is only possible then when the reception of a release signal coming from the direction of the surface he follows.
  • This configuration ensures that an uncontrolled actuation of the device in any direction is not possible. On the one hand, this ensures that a viewer does not direct rays to the rest of the audience. In addition, by not emitting the release signal, it can be prevented that, regardless of the direction of the beam desired by the respective viewer, no beams can be emitted at certain times.
  • control unit is connected to a display device which is set up to display an optical, acoustic or tactical signal which is recognizable to the user of the device.
  • the playback device can also emit several signals (e.g. optical and tactile). With this, the respective viewer can e.g. be signaled that his respective device has received an enable signal and that he can now make a mark on the projection surface.
  • an identification signal can be sent to the devices, which identification signal is received by the receiver and evaluated in the control unit of each device, i.e. is compared with the identifier of the respective device. If the comparison is positive, the control unit can also activate the display device accordingly, so that the respective viewer knows that "his" beam is detected and e.g. is taken into account in the manner described above.
  • control unit is connected to a sound recording device which is set up for this is to record sounds and send them to a receiver for transmission in the auditorium by means of a transmission device.
  • the viewer selected via the identification signal can thus speak to the rest of the audience. It is also possible to present the voice of the selected viewer (eg together with a previously recorded image of the viewer on the projection surface) to the rest of the audience.
  • control unit is set up to use the signal received by the receiver to transmit a signal transmitted into or with the release signal To determine the duration signal and to generate the drive signal for the converter as a function of the duration signal. This ensures that every viewer cannot direct (light) rays onto the screen for any length of time.
  • the transmitted time signal can either be the maximum
  • Time period for an uninterrupted (light) beam can be specified, and / or the time duration signal specifies how long the accumulated time period is, during which the viewer can direct any number of (light) beams onto the projection surface.
  • the control unit assigns e.g. a counter, which is set to a certain value by the time duration signal. The counter is decremented during the time in which the viewer actuates the signaling device to direct a (light) beam onto the projection surface. As soon as the counter has reached zero, the control unit blocks the generation of the control signal for the converter (regardless of whether the signaling device is actuated or not).
  • control unit can be set up to determine a number of light pulses transmitted in or with the release signal and control signals for to generate the converter depending on the number of light pulses.
  • control unit has a counter which is set to a specific value by the light pulse number signal. This counter is decremented each time the viewer actuates the signaling device to direct a (light) beam onto the projection surface. As soon as the counter has reached zero, the control unit blocks the generation of the control signal for the converter.
  • control unit can be set up to determine a group identification signal transmitted in or with the release signal and to generate control signals for the converter as a function of the group identification signal.
  • control unit has a storage element in which a predetermined group membership feature (a combination of numbers or bits) is stored. If a group identifier signal is transmitted in or with the release signal, the control unit compares the content of this memory element with the received group identifier signal. If the comparison is negative, the control unit blocks the generation of the control signal for the converter.
