Background technology
Along with multimedia development, all widespread use multimedia technologies in teaching or various academic forum, as PPT, FLASH etc., application of multimedia technology can increase the vividness of lecture contents.In academic activities, when expert, scholar explain, be also widely used multimedia.
In multimedia teaching, main infrared remote control laser pen, wireless and bluetooth mouse, the e-Pointer etc. of using are controlled and are inputted at present.
Infrared remote control laser pen is a electronic product that is applicable to carry out on computing machine and multimedia projector e-file demonstration, use in developed countries such as America and Europes is very general, it only has outside laser indication function at conventional laser teacher's pointer, increased the function of remote control file page turning, only need press simply the upper and lower page-turning button of laser pen, just can the upper and lower page turning of wireless mode remote control computer, making demonstrator can not touch computing machine just can be to the free page turning of electronic document and arbitrarily demonstration.But its service range is limited, and can not add picture and text, annotation etc., and laser there is very major injury to eyes.
Wireless and bluetooth mouse also plays a role in teaching, but its service range is short, and will be placed on the enterprising line operate of plane.Teachers, in the process of teaching demonstration, often need to be sitting in computing machine side, while operate computing machine, explain, and the multimedia presentation equipment of originally providing convenience, has but been fettered the abundant body language of teachers.
In the presentation process of PPT, FLASH etc., also often use e-Pointer, although it can add the operations such as annotation, picture and text in presentation process, it uses inconvenient, operating distance is very short, and must operate with mouse or keyboard.
These several devices and mode of operation are all encountered such embarrassment in teaching or various academic forum, as change the content of projector slide and carry out the operations such as upper and lower page turning, when suitable interpolation annotation and picture and text, explanation person has to get back to computing machine side and completes by mouse or keyboard, this brings great inconvenience to explanation person, also the thinking and the explanation effect that affect explanation person, this seems and especially highlights while giving lessons to student for teacher.Thorough liberation is out when teaching demonstration how to allow user, real realize " where walk; where say; where say, where point to ", user can arbitrarily be walked about when teaching, demonstration, bring into play to greatest extent the advantage of body language, make teaching, speech more lively, more perfect, become to be badly in need of a great problem that solves.
Summary of the invention
Object of the present invention is exactly for above-mentioned deficiency, provide a kind of three dimensions to write telechiric device, it can make user leave computing machine to carry out three dimensions and write, remote control, when teaching demonstration, can arbitrarily walk about, with being intended to spatial operation, add picture and text, annotation etc., bring into play to greatest extent the advantage of body language, allow teaching, give a lecture more lively, more perfect, thorough liberation is out when teaching demonstration to make user, be not subject to space constraint, can realize lantern slide content changing compared with far range control multimedia computer, write, draw, the operations such as upper and lower page turning, and easy and simple to handle, volume is little, low in energy consumption, low cost of manufacture, carry with easy to use, practicality is very strong.
For achieving the above object, technical scheme of the present invention is, this three dimensions is write telechiric device, comprise mobile terminal, fixed terminal, PC, described mobile terminal comprises data acquisition unit, transmitting terminal data processing unit, wireless transmitting unit, described data acquisition unit has acceleration transducer, gyroscope, button, described acceleration transducer, gyroscope, button is connected with transmitting terminal data processing unit respectively, this transmitting terminal data processing unit is connected with wireless transmitting unit, described fixed terminal comprises receiving end data processing unit, accept the radio receiving unit of wireless transmitting unit information, this radio receiving unit is connected with receiving end data processing unit, this receiving end data processing unit is connected with PC.
The acceleration transducer of described data acquisition unit, gyroscope, button, and transmitting terminal data processing unit, wireless transmitting unit to be integrated in described mobile terminal inner.
It is inner that described radio receiving unit, receiving end data processing unit are integrated in described fixed terminal.
The data that the button of mobile terminal of the present invention, acceleration transducer and gyroscope gather, send to fixed terminal by wireless transmitting unit; Fixed terminal receives the data from mobile terminal, utilize the accekeration of the spatial triaxial of microprocessor degree of will speed up sensor collection to be converted to the track of three axles, become angular velocity to be transmitted to PC the data-switching of gyroscope collection, by PC, draw and operate, thus the function of implementation space handwriting input.
The present invention adopts 3-axis acceleration sensor and gyroscope to detect operational motion, by the acceleration detecting and angle-data by integral operation, the parameters such as perception angle, speed, displacement.
The present invention is integrated in mobile terminal, and the action that sense operation person's hand or other organ move realizes input, drawing and the control on PC according to the data of sensor collection.
The present invention is based on 3-axis acceleration sensor and gyroscope input equipment, can depart from two dimensional surface, at three dimensions control PC, draw, write etc.; In addition due to 3-axis acceleration sensor and gyroscope volume small, can be mass, precision is higher, can design based on it the input equipment of various shapes and function.
The present invention is not subject to space constraint, can compared with far range, control the operations such as multimedia computer is realized lantern slide content changing, writes, drawn, upper and lower page turning, and easy and simple to handle, and volume is little, and cost is low, low in energy consumption, and practicality is very strong.
The present invention has inherited all advantages of existing product, can realize and leave computing machine in functions such as space drawing, annotations, and in order to facilitate data to transmit and to realize wider range of application, the present invention adopts wireless communications mode, and operating distance is over 100 meters.
The present invention can be widely used in classroom instruction and academic report, can make user leave computing machine carries out three dimensions and writes, remote control, when teaching demonstration, can arbitrarily walk about, with being intended to spatial operation, add picture and text, annotation etc., bring into play to greatest extent the advantage of body language, allow teaching, give a lecture more lively, more perfect, thorough liberation is out when teaching demonstration to make user, be not subject to space constraint, can realize lantern slide content changing compared with far range control multimedia computer, write, draw, the operations such as upper and lower page turning, and easy and simple to handle, volume is little, low in energy consumption, low cost of manufacture, carry with easy to use, practicality is very strong.
