Definitions
- the utility model relates to computer control systems (computer interfaces) through the impact on the image created on the screen by the projector, and can be used to ensure user interaction with the computer during presentations or educational events.
- presentation software products provide tools for interactively interacting with presentation content.
- the presentation often consists in demonstrating the operation of a program.
- the speaker can control applications on the computer. Including working with documents, making changes to the presented material, making notes and so on.
- the speaker spends additional time on his own movements, including the fact that he periodically approaches and bends to the computer.
- Known electron-optical manipulator including a radiation source in the form of a light pointer and a video camera connected to a computer and fixing the movement of the light spot on the screen onto which the image transmitted from the computer is projected (see patent US 51 15230, class G06F 3/00, publ. May 19, 1992).
- the disadvantages of the known device are the need to use specific equipment and the complexity of its installation, which is not allows you to provide high-quality presentation in those rooms where there is only a computer and a projector (or large monitor).
- the objective of the utility model is to eliminate these drawbacks.
- the technical result consists in simplifying the design of the device while maintaining its efficiency.
- the electron-optical manipulator which includes a radiation source in the form of a light pointer and a video camera connected to a computer and fixing the movement of the light spot on the screen onto which the image transmitted from the computer is projected;
- the radiation source is a laser or LED, the radiation of which lies in the infrared range of the spectrum, and an infrared filter is installed in front of the camera lens.
- Figure 1 shows the radiation source in the form of a light pointer
- figure 2 elements of equipment necessary for the presentation
- Fig. 3 is a signal exchange diagram.
- the principle of operation of the proposed device is based on the sensitivity of CCDs (charge-coupled devices) of most cameras, including cameras of mobile devices and webcams, to the light of that part of the light range that is invisible to the human eye.
- This application is about the infrared (IR) wavelength range.
- the light belonging to this region has a wavelength range from 740 to 2500 nm, but it is preferable to use the range of the light source and filter to 1000-1 100 nm, since most CCD matrices effective sensitivity decreases greatly with a further increase in wavelength.
- the choice of the specified range allows using the filter to highlight the position of the light point on the plane.
- the prevalence of laser and diode sources, the radiation of which lies in the HF range of the spectrum greatly simplifies the search for components for the proposed device.
- the electron-optical manipulator itself is a set of a light filter 1 and a light (laser or just LED) pointer 2 installed in front of the camera, both of which work in the short-wave region of the infrared (RH) range of the spectrum.
- a light filter 1 and a light (laser or just LED) pointer 2 installed in front of the camera, both of which work in the short-wave region of the infrared (RH) range of the spectrum.
- Light pointer 2 (Fig. 1) includes a housing 3 for a power source (battery, battery or a set thereof) and a light source 4 (RJ laser LED or conventional RJ LEDs). At least 3 on / off buttons of the RJ light source are located on the housing 3 (other control buttons may also be equipped).
- the cover of the battery pack 6 may be located on one side of the housing 3.
- the design of the cap 7, if provided, may vary depending on the type of light source 4.
- the place for presentation (figure 2), in addition to the standard computer 8, projector 9 and screen 10, is equipped with a camera 1 1.
- a light pointer 2 At the speaker in the hand is a light pointer 2, which is used by him for presentation and for commands to move the cursor.
- a light filter 1 In front of the camera 1 1 there is a light filter 1, which together with the camera 1 1 is a signal receiver from the light pointer 2 and a source of data about its movement for the computer).
- the signal receiver (camera 1 1) may be a camera embedded in a computer, a separate camera, or a camera of a mobile device.
- the speaker can give point commands to move the cursor or draw lines, draw, etc., touching or not touching the surface of the screen with the emulator, including pointer 2 at the right moments.
- the principle of operation of the proposed device is to put 2 marks on the screen 10 using the IR light pointer, select 1 light signals 2 using the IR filter 1, and then fix only the light pointer 2 signals. Next, these signals must be converted to the operating system commands of the cursor control computer.
- Computer 8 transmits a signal to projector 9.
- Projector 9 projects the image on screen 10.
- the image drawn on screen 10 with light pointer 2 enters camera 1 1.
- Camera 1 1 transfers the position of the light spot from pointer 2 to the computer in raw or processed mode (in form of coordinates X, Y) form.
- Processing an optical signal consists of the following steps: 1. [Preparatory] Calibration of the coordinates of the projection angles of the image relative to the angles of the visible part of the camera.
- the coordinate processing is performed using the computer driver.
- the computing power of modern mobile devices is sufficient not only to transfer the cursor position to the computer, but also to calibrate the visible part of the image and coordinate conversion in order to transmit the exact coordinates of the light spot relative to the corners of the image on the screen of the projector and computer.
- the proposed utility model allows you to easily and quickly adapt ordinary demonstration equipment for the tasks of a comprehensive interactive presentation, simply by installing a light filter in front of a standard video camera.
