Briefing system

The present invention provides a presentation system, and more particularly to a presentation system for controlling presentation content using infrared wireless.

Most of the speakers on the stage used computers to make presentations for the audience to watch. In the course of the speech, the speaker often uses the laser pointer to point to the projection screen of the presentation, in order to prompt the audience to present the briefing content corresponding to the speech. In addition, the speaker will also use a laser pointer with a page change function to report, in addition to launching the laser light to the current newsletter page, the above-mentioned laser pointer can also be used to make a page change action on the current briefing page, so that the speaker does not Need to operate the page change function of the computer.

However, in the process in which the speaker uses a laser pen to emit laser light, the viewer's eyes are often uncomfortable because the laser light strikes the viewer's eyes. In addition, when the speaker hopes that the audience can understand the key points of the content, the current practice is to increase the tone of the report when speaking to important briefings. If the audience in the audience temporarily leaves the office, it will be difficult to know the focus of the report from the content of the briefing afterwards. Another common practice is to mark the focus on the newsletter page before the presentation to present it at the presentation. However, this practice does not provide the speaker with a temporary mark to other new priorities.

Therefore, in the course of the speech, if the speaker can speak on the stage with a device that is not a laser pen, it will avoid the laser light from shining to the viewer's eyes. In addition, if the speaker's handheld device can instantly mark the focus, it will attract the audience's attention and provide the speaker with the mark at any time.

In addition, the same reference numerals may be used in the drawings to represent similar elements.

The briefing system provided by the embodiment of the present invention controls a position of a sensing surface of a control element that emits infrared rays to an infrared receiving unit to control a cursor displayed in a developing plane. In addition, the presenter can control the cursor to produce a special effect on the imaging plane by operating the control element. The briefing system provided by the embodiment of the present invention will be further described below.

First, please refer to FIG. 1, which shows a schematic diagram of a briefing system according to an embodiment of the present invention. As shown in FIG. 1, the presentation system 100 remotely controls a cursor P displayed in the development plane 140 through infrared technology. The presentation system 100 includes a control component 110, a detection component 120, and a computer host 130. The host computer 130 is coupled to the detecting component 120 via a first Bluetooth transmission TR1 and is coupled to the control component 110 via a second Bluetooth transmission TR2. The control component 110 is configured to emit an infrared ray to one of the sensing surfaces 122 of the detecting component 120. Detection element 120 The positional relationship between the infrared RED and the sensing surface 122 will be wirelessly transmitted to the host computer 130. The computer host 130 displays the cursor P associated with the positional relationship on the development plane 140 according to the positional relationship between the infrared RED and the sensing surface 122. In other embodiments, the presentation system 100 can further include a projector (not shown) electrically connected to the computer host 130, and projected to the display according to the cursor P transmitted by the host computer 130 associated with the positional relationship. Like plane 140.

Furthermore, please refer to FIG. 2 at the same time, which shows an internal architecture diagram of the briefing system according to an embodiment of the present invention. As shown in FIG. 2, the control component 110 has an infrared emitting unit 116, and emits an infrared RED to the sensing surface 122 of the detecting component 120 according to an opening and closing signal SC. In the present embodiment, the infrared emitting unit 116 is a detachable component and is disposed at a place where the control element 110 is placed. The infrared emitting unit 116 can also be embedded in the control element 110, which is not limited in the present invention.

The control component 110 of this embodiment is a smart phone, and the PAL is the earphone hole of the smart phone. When the speaker wants to use the infrared emitting unit 116, the speaker can screw the infrared emitting unit 116 into the earphone hole of the smart phone, so that the infrared emitting unit 116 is electrically connected to the smart phone. The opening and closing signal SC is controlled by a button BT1 on the smart phone. Therefore, when the presenter presses the button BT1, the infrared emitting unit 116 will receive the opening and closing signal SC and emit the infrared RED. The opening and closing signal SC can also be controlled by a control interface 112 on the smart phone to generate the opening and closing signal SC by pressing the control interface 112, which is not limited in the present invention. The mechanism for the speaker to control the infrared ray emitting unit 116 to emit the infrared RED may be configured according to the actual usage habit of the presenter, and is not intended to limit the present invention. For example, the speaker presses the first button BT1 to emit infrared RED, and presses the button BT1 again to turn off the infrared RED.

The detecting component 120 includes an infrared receiving unit 126 and a position estimating unit 128. The infrared receiving unit 126 is electrically connected to the position estimating unit 128 and has a sensing surface 122. The infrared emitting unit 116 emits infrared RED to the sensing surface. A sensing position POS of 122. Next, the position estimating unit 128 will determine that the infrared RED is located at the sensing position POS of the sensing surface 122. For example, the sensing surface 122 is a rectangular sensing surface of 10 cm*8 cm, and the infrared emitting unit 116 emits infrared RED to a position of 2 cm*5 cm in the sensing surface 122. Therefore, the position estimating unit 128 determines that the sensing position POS of the infrared RED in the sensing surface 122 is, for example, a coordinate (2, 5), and transmits a coordinate (2, 5) representing the sensing position POS to the host computer 130. . The sensing position can also be expressed in other ways, which is not limited by the present invention. In order for the position estimating unit 128 to determine a more accurate sensing position, the infrared receiving unit 126 of the detecting element 120 is fixedly disposed in a range in which the infrared RED emitted by the infrared emitting unit 116 can be received. Preferably, the infrared receiving unit 126 is fixedly disposed on the developing plane 140 so that the presenter can face the developing plane 140 to make a speech, and the position estimating unit 128 can determine a more accurate sensing position.

The host computer 130 includes a label conversion unit 136 and a processor 138. The coordinate conversion unit 136 has a screen coordinate system (not shown), and the screen coordinate system has a proportional relationship with the sensing surface 122. The coordinate conversion unit 136 wirelessly receives the sensing position POS through the first Bluetooth transmission TR1, and converts the sensing position POS into a cursor position POM conforming to one of the screen coordinate systems according to the proportional relationship. That is to say, the above proportional relationship between the cursor position POM and the sensing position POS is also the same.

For example, the proportional relationship between the sensing surface 122 and the screen coordinate system is twice. That is, if the coordinate conversion unit 136 receives the sensing position POS as a coordinate (2, 5), the coordinate conversion unit 136 converts the sensing position POS, that is, the coordinate (2, 5), according to a proportional relationship of 2 times. Corresponds to the cursor position POM of the screen coordinate system, ie coordinates (4, 10). Of course, the proportional relationship between the sensing surface 122 and the screen coordinate system can also be expressed in other ways, which is not limited by the present invention.

The processor 138 is electrically coupled to the coordinate conversion unit 136 and displays the cursor P at the cursor position POM of the development plane 140 in accordance with the screen coordinate system. Therefore, as shown in Figure 3A As shown, when the presenter holds the control element 110 to press the button BT1, the infrared emitting unit 116 disposed on the control element 110 will receive the opening and closing signal SC and emit infrared RED to the sensing position POS of the sensing surface 122. Then, the position estimating unit 128 of the detecting component 120 will wirelessly transmit the sensing position POS to the coordinate converting unit 136 of the computer host 130 through the first Bluetooth transmission TR1 after determining the sensing position POS. The processor 138 of the host computer 130 will display the cursor P at the cursor position POM of the development plane 140 according to the screen coordinate system. Accordingly, the presenter will be able to utilize the control element 110 that emits infrared RED to control the cursor P displayed in a development plane 140 to prompt the viewer to present the presentation content corresponding to the current presentation. In other embodiments, the presentation system 100 can further include a projector (not shown) electrically connected to the computer host 130, and project the cursor P to the imaging plane according to the cursor position POM transmitted by the processor 130. 140.

Referring back to FIG. 1 and FIG. 2, it is noted that the control component 110 further includes a data transfer unit 118. The data transmission unit 118 wirelessly transmits a function signal FUN to the processor 138 of the computer host 130 via the second Bluetooth transmission TR2. In this embodiment, the control component 110 is a smart phone, and the function signal FUN is controlled by a button BT2 on the smart phone. Therefore, when the presenter presses the button BT2, the processor 138 of the host computer 130 will receive the function signal FUN wirelessly transmitted by the data transfer unit 118. The function signal FUN can be controlled by the control interface 112 on the smart phone to generate the function signal FUN by pressing the control interface 112. The present invention does not limit this. The mechanism by which the speaker control data transmission unit 118 wirelessly transmits the function signal FUN can be configured according to the actual usage habit of the presenter, and is not intended to limit the present invention. For example, the speaker continuously presses the button BT2 to generate the function signal FUN, and the release button BT2 does not generate the function signal FUN.

Next, the processor 138 will control the cursor P to generate a special effect on the development plane 140 according to the function signal FUN. For example, the cursor P displayed on the development plane 140 is changed to another graphic, or is executed on the cursor P displayed on the development plane 140. Other special effects are not limited by the present invention.

It is to be noted that the special effect of the present embodiment is to display the movement trajectory of the cursor P on the development plane 140. The speaker presses the button BT2 to generate the function signal FUN, and the release button BT2 does not generate the function signal FUN for explanation. As shown in FIG. 3B, the infrared emitting unit 116 disposed on the control element 110 continuously emits infrared RED to the sensing surface 122. At this time, when the speaker holds the control element 110 and presses the button BT2, the data transmission unit 118 disposed on the control element 110 will receive the function signal FUN and wirelessly transmit it to the processor of the computer host 130 through the first Bluetooth transmission TR1. 138. Next, the processor 138 will control the cursor P to produce a special effect on the development plane 140. That is, the processor 138 will record the movement trajectory of the cursor position POM according to the function signal FUN, and display the movement trajectory MOV of the cursor P on the development plane 140. Therefore, when the presenter moves the control element 110 such that the infrared RED on the sensing surface 122 is moved from the sensing position POS1 to the sensing position POS2, the processor 130 will record the movement trajectory MOV of the cursor position POM.

When the speaker releases the button BT2, the data transfer unit 118 will not receive the function signal FUN. Next, the processor 138 will display the movement trajectory MOV of the cursor P on the development plane 140 and simultaneously display the cursor P. According to this, the speaker can mark the key points at any time by operating the control element 110, and can interact with the audience under the audience and attract the attention of the audience. In addition, the speaker can save the moving track MOV of the cursor P and the briefing content to a storage unit of the computer host 130 by pressing a certain control button of the control component 110 or a certain control key of the computer host 130 (not shown in the figure Medium), so that the movement track MOV of the cursor P (that is, the focus of the speaker at any time) can be retained in the briefing content.

In summary, the briefing system provided by the embodiment of the present invention controls a cursor displayed in a developing plane by using a control element that emits infrared rays. In addition, in the process of the speech, if the speaker wants to draw the attention of the audience, as long as the drawing is drawn through the handheld control element (such as a straight line or a circle), the imaging plane will simultaneously display the drawn graphic, and then Cause the audience to pay attention to the audience, and provide the speaker to mark at any time Focus.
