Problems solved by technology

Therefore, there are cases where the viewer, who is the operator of the laser pointer, is pointing at the screen when they turn their gaze to the screen again after taking their eyes off the screen.
In particular, when using a self-illuminating liquid crystal display or the like, the spot of the laser light is buried in the screen, and it is not easy to find the spot immediately.

Embodiment Construction

[0049] One embodiment of the present invention will be described with reference to the drawings.

[0050]

[0051] The display system of this embodiment is assumed to be used in meetings, lectures, classrooms, etc., such as figure 1 As shown, it is configured to include: an information processing device 1 having a function of outputting a signal for causing a display device to display a screen 6 on which an image 7 for presentation is drawn; The receiver 3, which is connected to the information processing device 1, receives the information sent from the operating device 2 and provides it to the information processing device 1.

[0052] In the illustrated example, the display device is a projector 4 that projects a screen 6 onto a screen 5 (or a wall surface). However, the display device is not limited to the projector 4, and may be a liquid crystal display or other devices.

[0053] like figure 2 As shown, the information processing device 1 is like a general-purpose per...

Abstract

Provided is a suitable presentation system, wherein an inconvenient point of a laser pointer in that a luminescent point thereof is difficult to find is solved. In order to solve this problem, a system was configured combining: an information processing apparatus (1) that outputs a signal for displaying a screen (6) on a display, or for projecting the screen (6) with a projector (4); and an operating device (2) that can communicate with the information processing apparatus (1), and that is to be held and operated by an operator. The operating device (2) has mounted thereon a gyroscope sensor for detecting the moving direction of the operating device (2). The information processing apparatus (1) receives moving-direction information to be obtained from the operating device (2), determines a drawing point within the screen (6) at which a cursor (81) is to be displayed in accordance with the moving direction, draws the cursor (81) at that point, and also draws an indicating line (82) that links the cursor (81) and an outer rim section of the screen (6).

Description

technical field [0001] The present invention relates to a presentation system used when presenting to a plurality of audiences. Background technique [0002] It is not uncommon to use a laser pointer as a prop to indicate a desired position within a screen displayed on a large display or projected on a large screen via a projector. Recently, a laser pointer with a remote control function capable of communicating with a personal computer in charge of drawing a screen and instructing page-down of a presentation slide is also distributed on the market (for example, refer to the following patent documents). [0003] In terms of the characteristics of laser light, the light spot of the laser light emitted from the laser pointer and projected on the surface of the display or screen is very small. Therefore, there are cases in which the viewer may not know where the speaker, that is, the operator of the laser pointer, is pointing at on the screen when they turn their gaze to the s...
