Description
Affiliated technical field
The utility model relates to a kind of institution of higher education computer teaching device, relates in particular to the mutual telechiric device in a kind of computer teaching classroom.
Background technology
Along with popularizing and development of computing machine, people are also increasingly high to the requirement of education.The multimedia presentation technology has been come in the classroom and the academic report Room of universities, improves the quality of teaching and has great significance improving audio visual effect.It is to replace traditional blackboard with screen; Under software environments such as PowerPoint, import computing machine to the content that will lecture, pass through projector projects again to screen, the content that teacher's hand takes the religion bar to point in the screen is explained; When one or a screen content are said and be over; Get in the next one a perhaps screen, two kinds of ways are arranged, by first teacher goes to computing machine from the left side of screen or the right; Dub a key (normally space bar) that hits on the lower keyboard or click left mouse button with light finger, next content just appears in the screen.The shortcoming of this method is: in teaching process, the teacher must ceaselessly run between projection curtain wall and computing machine back and forth, both consumes one's strength, and influences teaching efficiency again, and computing machine is other teaches if the teacher only is sitting in, and its effect is inevitable undesirable; Also influenced teaching process simultaneously, extremely inconvenient.It two is to accomplish through the card time, be exactly the teacher when multimedia courseware is made, set the demonstration time of explanation content, this time equals teacher's the instruction time just, when this teachings finishes, it will automatically show in the next one perhaps next screen.Instruction person must explain by the word speed that pre-sets, content, otherwise lecture and displaying contents inconsistent, and this inconsistency often occurs, and influenced the concordance of content.The general solution of people is to use the keyboard and the mouse of infrared and radio remote control now; But its command range also has only several meters far away, and volume is big simultaneously, is inconvenient to be with the destage face to use; And infrared and radio keyboard and mouse also have the restriction of transmission of angle, and on the classroom, using has inconvenience.
Summary of the invention
The purpose of the utility model provides the mutual telechiric device in a kind of computer teaching classroom, it can handled easily with carry, assist the teacher to accomplish the Play Control of PPT, accomplish teaching task better.
In order to solve the problems of the technologies described above, the utility model is realized through following technical scheme:
The mutual telechiric device in computer teaching classroom; Comprise wireless control module and the wireless communication module that is connected with computing machine; The wireless communication module that is connected with computing machine is connected with USB interface of computer; It is characterized in that: described wireless control module is box-like, and its end face is provided with trace ball, is provided with elastic bands in the bottom surface.
Further, described wireless control module is provided with the laser nib, and a switch is electrically connected with described laser nib.
Further, a side of described wireless control module is provided with the operating key corresponding to three buttons of mouse.Realize the mouse corresponding operating through described three operating keys.
The use of the utility model is following:
Wireless communication module is inserted the computing machine USB interface of playing PPT; Utilize elastic bands that wireless control module is fixed on the palm, open switch, can make laser pen and use; Available thumb manipulation trace ball control cursor moves, and its effect is equivalent at the desktop rolling mouse; When needs operations PPT, can be with other fingers by described operating key, its effect is equivalent at the desktop button of clicking the mouse.
The beneficial effect of the utility model is:
Compact conformation, the ergonomic requirement can be fixed on the palm through elastic bands, and is simple to operate, realizes mouse function fully, also is provided with laser pen, and one-object-many-purposes assists the teacher to accomplish the classroom instruction task better.
