In terms of the touch interface, most of the current users use the contact or sensing behavior generated between the finger or the stylus and the touch input interface to perform a click action, so that the electronic device can utilize the coordinate change of the touch point. Or the number of touch points is increased or decreased to define a user's touch gesture, and then the corresponding operation function is performed according to the touch gesture. In an optical projection system, it is impractical for a user to input commands through a touch interface such as a touchpad or a touch panel. Therefore, if 1 吏, the person can directly operate on the screen of the projection system by projecting the light spot, which can not only subvert the traditional input mode of the keyboard, but also greatly improve the convenience of using the projection system. In the current design, the sensing range of the projection system will change after the projection system and the projection screen change. These four are determined by the projection pen in front of the projection screen. ^The system re-determines the correct sensing range. Also, after the distance between the system and the projection screen is changed, manual positioning must be performed using 1^400-1199 36757twf.doc/n 201227411. Because ^ 乂 ^.0,, .

The projector body has a projection == configured on the projector body. A plurality of positioning light sources are arranged in the = and positioned around the projection lion. The sputum sensing is determined: the projected light of the light source is projected on the position of the screen to determine a sensing range. λ The present invention further proposes an operation method of an interactive projection apparatus. The interactive device is also equipped with a projector, a sensor, a plurality of positioning light sources, and a projection lens. The sensor is disposed on the projection multi-machine body, and the clamping light source is disposed on the projector body and located around the projection lens. The operation method of the rotary projection device comprises: turning on the positioning light source to cause each 1-bit light source to emit - the projection light is projected on the screen; the sensor sensing the position of the projection light projected on the screen to determine a sensing range; and turning off the positioning light source ; and projected by the projection lens and interactively sensed by the sensor. Based on the above, the present invention directly sets the positioning light on the interactive projection device 201227411. A light source for w400-1199 36757twf.doc/n, so that the sense (4) can self-position the range to be sensed. As a result, after changing the projection environment, the user does not need to manually re-define the position of the sensing range. Therefore, the interactive projection device of the present invention has good practicability and convenience. The above described features and advantages of the present invention will become more apparent from the following detailed description of the embodiments. [Embodiment] - Fig. 1 is a front view of an interactive projection apparatus according to an embodiment of the present invention. Referring to Figure 1, the interactive projection apparatus 100 includes a projector body 110, a phase g (10), and a plurality of positioning wires (10). The projector body 110 has a projection lens 112. The sensor 12A is disposed on the projector body 110. A plurality of positioning wires 13G are disposed on the projector body (10) and are positioned around the projection lens 112. In order to clearly illustrate the spirit of the present invention, the present embodiment only simplifies the projector body 110. Specifically, the projector body 11G includes, in addition to the projection lens 1 =, a support frame 114 and a connection terminal (not shown), a projection light machine, a display panel, a heat sink, and the like. This embodiment does not particularly limit the constituent members of the projector body UG. Any implement that can be connected to a computer or a host to project an image can be used as the projector body 110 of the present embodiment. In general, projector body 110 provides the ability to project an image. However, with the introduction of various touch-sensitive products, the user's interaction requirements for human-machine interaction are increasing, so the simple projection function is no longer ------- U400-1199 36757twf.doc/n User needs. In the present embodiment, in addition to being able to project an image, the mutual subtraction projection device 100 can also display a (four) image in the face according to the user's motion. For example (4), the wire projection device brain can further include a projection pen (not shown). When the user causes the professional pen (not shown) to trace the line in the _ of the image, the sensing device α 120 丝 on the wire projection device 100 senses the trajectory of the line to the line Painted in the projection screen. In this way, the user can see the line in the multi-faceted projection screen projected by the interactive shirting device 100, and provide a more convenient operation mode for the user. In addition, the user can also use the projection pen (not shown) to click on the icon in the projection face to perform a specific function. Although the interactive projection apparatus 100 can provide a relatively convenient operation method, the interactive projection apparatus 100 must correctly determine the range to be sensed in order to correctly determine the information given by the user. 2 is a side view of an interactive projection apparatus according to an embodiment of the invention. Referring to Fig. 2, in the present embodiment, each of the positioning light sources 13A can project the projection light L before the interactive projection device 100 interacts with the user. At this time, the sensor 120 can sense the position P of the projection light L projected on a screen 1 to determine a sensing range SA. In other words, before interacting with the user, the sensor 12A on the interactive projection device 1 can first determine the sensing range SA based on the projected light L emitted by the positioning light source 130. As a result, the sensing range SA is not determined manually, and the practicality and ease of use of the interactive projection apparatus are greatly improved. The interactive projection device 100 includes a switching element 14A disposed on the projector body 110 and electrically connected to the positioning light source 13〇201227411 ^00-1199 36757twf.doc/n to control the positioning light source 13〇. Turn it on and off. When the user thinks that it is necessary to re-determine the sensing range SA, these clamping light sources 13 can be turned on by the switching element 140. Once the sensing range SA is determined, the positioning light source 13A can be turned off by the switch element 140, which can prevent the sensor 120 from confusing the projection light L of the positioning light source 13〇 with the projection pen (not shown). - the light. Of course, the positioning light source 13A may be a plurality of infrared light sources that are different from the visible light projected by the projection pen. At this time, if the sensor 12 can correctly distinguish visible light and infrared light, it is not easy to cause confusion between the light source L and the light of the projection pen (not shown). However, the light projected by the projection pen may not be visible light, and the embodiment is not limited thereto. Referring to FIG. 1 and FIG. 2 at the same time, in general, the sensing range SA is preferably the same as the projected image projected by the projection lens 112 and the mechanism between the positioned light source 130 and the projection lens 112. Optical negligence has a specific relationship. In the present embodiment, the number 1 of the positioning light sources 13A is, for example, four, which is enclosed in a rectangle to surround the projection lens. The projection light L of the four positioning light sources 投射3 投射 is projected on the screen 1 • • The (f) position f P is preferably the four corners of the projection pupil projected by the projection lens 112. That is to say, the projected light L should be emitted along the edge of the projected picture. Therefore, in the present embodiment, the projection light L of each of the positioning light sources 130 exhibits an emission angle equal to that of the projection ray μ of the projection multi-lens η2. Further, a straight line connecting the adjacent two positioning light sources 13 = = the edge of the projection lens 112. With such a design, regardless of the distance between the projection and the screen 10, the positions p of the four positioning light sources 130 that are projected on the screen 1 can be placed in the projection mirror ^400-1199. 36757twf.doc/n 201227411 The four corners of the facet projected by the head 112 correctly define the sensing range SA. Of course, the present embodiment does not limit the position p at which the projection light L of the four positioning light sources 130 is projected on the screen 位 in the four corners of the screen projected by the projection lens 112. The method of operation of the interactive projection apparatus 100 includes the following steps. First, the positioning light source 130 is turned on to cause the respective positioning light sources 13 to emit projection light [projected on the screen 10. Next, the sensor B is sensed by the sensor 12 to project a position P of the screen 10 to determine the sensing range SA. Then, the positioning light source 130 is turned off, projected by the projection lens 112, and interactively sensed by the sensor 12A. In the present embodiment, the determination of the sensing range SA has been completed before the interactive projection apparatus 1 performs the interactive sensing. Therefore, the interactive projection device 100 can perform interactive sensing in the correct sensing range SA. In addition, when the interactive projection device 100 performs interactive sensing, the positioning light source 130 can be selectively turned off to achieve energy saving and power saving effects. Even the sensor 120 may be prevented from being misdetected. FIG. 3 is a schematic diagram of an interactive projection apparatus according to another embodiment of the present invention. Referring to FIG. 3, the interactive projection apparatus 2 includes a projector body 110, a sensor 120, a plurality of positioning light sources 13A, a switching element 14A, and a projection pen 210. The projector body 110 has a projection lens 112. The sensor 120 is disposed on the projector body 11A. A plurality of positioning light sources 13A are disposed on the projector body 110 and positioned around the projection lens. The switching element 140 is disposed on the projection pen 210, and the switching element 14 is electrically connected to the positioning light source 130 to control the opening and closing of the positioning light source 13A. Specifically, the interaction projection apparatus 200 is substantially the same as the interaction of the foregoing embodiment 201227411 ^400-1199 36757twf.doc/n type projection apparatus 100. The difference between the two is mainly as follows: • The setting position of the off element 140. Therefore, in addition to the ability to project images and interact with the user, the interactive projection device 200 can determine the sensing range for interactive sensing. In this way, the user does not need to stand in front of the projection screen 10 before each interaction in order to make the movable projection device 200 determine the correct sensing range, thereby improving the convenience of the interactive projection=200 setting. . In summary, the present invention additionally provides a light source for positioning on the projector body, and the projection light of the positioning light source is projected along the projector body, and the edge of the shadow image is emitted. Therefore, the interactive projection device can correctly determine the sensing range by sensing the position at which the positioning light source is projected on the screen. For this reason, the user needs to manually use the sense of mosquito to help improve the practicality of the interactive projection device. The present invention has been disclosed in the above embodiments, but it is not intended to limit the invention to those of ordinary skill in the art, and may be modified and retouched without departing from the spirit and scope of the invention. The protection of the present invention is determined by the patent application.
