Problems solved by technology

[0003] However, although the technology of the above-mentioned Patent Document 1 is a technology that uses the screen of the electronic blackboard as the projection object, it is also a technology that only specifies the position on the device operated by the pen, and cannot determine which one to use as the projection object and which one to use. The technology of projecting and displaying the display information of various contents
In addition, the technique of the above-mentioned Patent Document 2 is a technique for confirming changes in the position and shape of a display object and projecting and displaying it, but it is not capable of specifying which one is to be targeted and which content of display information is to be projected and displayed. technology
In addition, this situation is not limited to projector devices, and the same problem occurs even in other information output control devices

no. 2 approach

[0098] First, refer to Figure 9 to Figure 14 A second embodiment of the present invention will be described.

[0099] The second embodiment exemplifies the case where it is applied to a projector device with a camera as an information output control device that outputs display information, Figure 9 It is a figure which shows the usage example of this projector apparatus with a camera function.

[0100] The information output control device (projector device with camera) 10 includes a camera function, a communication function, and the like in addition to the projector function. The projector device 10 is used, for example, in a window business of a financial institution, etc., when a person in charge confronts a customer face-to-face while displaying a document on a desktop, or when a participant conducts a meeting while displaying a document on a desktop in a conference room Next, the entire tabletop is photographed or projected and displayed, and the projector device 10 i...

no. 3 approach

[0137] Below, refer to Figure 15 to Figure 20 A third embodiment of the present invention will be described.

[0138] Further, in the second embodiment described above, the projector device 10 is exemplified as the information output control device, the electronic paper 3 is exemplified as the output object, the projection-capable area 2 on the desktop is exemplified as the predetermined area, and the input information is exemplified. However, in the third embodiment, a notebook PC (personal computer) is exemplified as the information output control device, the electronic paper 3 of the projection target is exemplified as the output object, and the display on the desktop is exemplified as the predetermined area. Device, handwritten information is exemplified as input information. Here, parts that are basically the same or have the same names in the two embodiments are denoted by the same symbols, and the description thereof will be omitted. The following description will foc...

Abstract

The invention relates to an information display control device. An object is to appropriately control the output of display information based on to which display target the display information is directed and in which area the display target is present. An information output control device (1) includes a display information memory for storing display information in association with a display target such as electronic paper (3) which is present outside the device. When a display target present in a predetermined area such as a projectable area (2a) is recognized and identified, display information associated with the display target is read out and acquired from the display information memory, the position of the display target present in the predetermined area (2a) is acquired, and the acquired display information is outputted such that it is displayed in association with the display target present at the acquired position.

Description

technical field [0001] The present invention relates to an information output control device for outputting display information. Background technique [0002] Generally, as an information output control device that outputs display information, for example, a projector device that uses a light source, a transmissive liquid crystal panel, or the like to project and display an image on an external projection object (display object: screen) is used. When the projector device projects various data (images) on the display object (screen) for presentation, the presenter or the like will orally explain the supplementary explanations, precautions, etc. based on the data on the screen, and explain the content on the screen. Indicate the necessary location. In this case, a technique of projecting a pointing trajectory of a pen on an image under projection onto an image under projection has been conventionally known (refer to Patent Document 1: Japanese Patent Laid-Open No. 2003-78686)...
