Abstract
The invention discloses a teaching instrument based on laser scanning. The teaching instrument comprises a multimedia projector, wherein a plurality of laser emitters are evenly arranged on the periphery of a curtain of the multimedia projector, and one laser receiver is arranged corresponding to one laser emitter; the laser emitters emit ultra-thin laser beams which irradiate the corresponding laser receivers from the place, close to the curtain, in front of the curtain; the multimedia projector is in a standby state; all the laser receivers can receive laser signals and present a high level externally. High-frequency scanning is performed on the laser receivers through a detection device; the specific position where a multimedia projector pointer is located or the specific position where a finger of a person before the multimedia projector is located and motion information thereof are obtained; then, corresponding commands are executed according to the display content of the position where the pointer or the finger is located; the curtain of the projector can be converted into a touchable control form, which is beneficial to user control, and user-friendly performance is better achieved.
Description
Technical field
The present invention relates to a kind of teaching appliance based on laser scanning.
Background technology
Multimedia technology is current areas of information technology technology with fastest developing speed, most active, it is the focus of electronic technology development of new generation and competition, multimedia technology melt computing machine, sound, text, image, animation, video and the several functions such as communicate by letter in one, by day by day universal High speed Information Network.Current multimedia teaching instrument mainly comprises fixed and movable, and it is large that fixed multimedia teaching instrument takies fixed venue, connects up loaded down with trivial details, and quantities is large, and the construction period is long.Movable its installation does not need fixed venue, but needs the power lead of various device and the signal wire of various device.No matter be fixed or movable, when having finger or teacher's pointer near screen, with regard to having corresponding laser signal, be blocked, thereby cause corresponding laser pickoff not receive light signal, the laser pickoff that does not receive light signal will externally present low level, reduced the control effect of user of service to projector, be inconvenient to operate.
Summary of the invention
In view of above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of teaching appliance based on laser scanning, the curtain of projector can be become to tangible control form, user is controlled more convenient.
For solving the problems of the technologies described above, the present invention program comprises:
A kind of teaching appliance based on laser scanning, it comprises multimedia projector, wherein, the curtain periphery of described multimedia projector has been evenly arranged a plurality of generating lasers, and each generating laser correspondence is furnished with a laser pickoff, and generating laser sends superfine laser beam, the place of pressing close to curtain from curtain the place ahead is radiated at corresponding laser pickoff, described multimedia projector is in holding state, and each laser pickoff can receive laser signal, externally presents high level.
Described teaching appliance, wherein, described multimedia projector also comprises a pick-up unit, the high-frequency scanning that described pick-up unit carries out laser pickoff, will obtain particular location and the movable information thereof of the front personnel's finger of described multimedia projector teacher's pointer or described multimedia projector, described pick-up unit sends to particular location and movable information thereof the control center of described multimedia projector after treatment, and the control center of described multimedia projector will and carry out corresponding order according to teacher's pointer or finger indication position display content.
A kind of teaching appliance based on laser scanning provided by the invention, the high-frequency scanning of laser pickoff being carried out by pick-up unit, obtain particular location and the movable information thereof of the front personnel's finger of multimedia projector teacher's pointer or multimedia projector, again according to teacher's pointer or finger indication position display content the corresponding order of execution, the curtain of projector can be become to tangible control form, user is controlled more convenient, more humane.
Accompanying drawing explanation
Fig. 1 is the structural representation of curtain in the present invention.
Embodiment
The invention provides a kind of teaching appliance based on laser scanning, for making object of the present invention, technical scheme and effect clearer, clear and definite, below the present invention is described in more detail.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
The invention provides a kind of teaching appliance based on laser scanning, as shown in Figure 1, it comprises multimedia projector 5, curtain 1 periphery of described multimedia projector 5 has been evenly arranged a plurality of generating lasers 2, each generating laser 2 correspondence is furnished with a laser pickoff 3, generating laser 2 sends superfine laser beam, the place of pressing close to curtain from curtain the place ahead is radiated at corresponding laser pickoff 3, described multimedia projector 5 is in holding state, each laser pickoff can receive laser signal, externally presents high level; On described curtain 1, be plugged with scanning code translator 4.
One, machine more, described multimedia projector also comprises a pick-up unit, the high-frequency scanning that described pick-up unit carries out laser pickoff 3, will obtain particular location and the movable information thereof of the front personnel's finger of described multimedia projector 5 teacher's pointers or described multimedia projector 5, described pick-up unit sends to particular location and movable information thereof the control center 6 of described multimedia projector 5 after treatment, the control center 6 of described multimedia projector 5 will and carry out corresponding order according to teacher's pointer or finger indication position display content, described control center 6 is generally desktop computer, the equipment such as notebook computer.
Based on laser scanning inspection shelter position and movable information and be used for controlling the instrument of other equipment, can be applied to a plurality of fields, as by the inductor of this equipment I on metope, can collect the movable information of finger on metope, and this information is used for controlling household electrical appliances.Such as drawing a circle with hand on the wall, this equipment will be carried out " turning on light " action.
Certainly; more than explanation is only preferred embodiment of the present invention; the present invention is not limited to enumerate above-described embodiment; should be noted that; any those of ordinary skill in the art are under the instruction of this instructions; that makes is allly equal to alternative, obvious form of distortion, within all dropping on the essential scope of this instructions, ought to be subject to protection of the present invention.
