Abstract
The invention is applied to a PPT projection apparatus especially designed for teachers. The apparatus is mainly composed of a loop (1), a red-light emitting device (2), and a Bluetooth connecting device (3) connected with a projection computer, and is characterized in that a ring is provided with the loop (1) which can be conveniently worn, the loop (1) is integrated with a pressure sensor, the projection of PPT is controlled through controlling the pressure sensor on the loop (1), and at the same time, the ring cooperates with the Bluetooth connecting device (3) connected with the projection computer for use. Two parts are combined together for aiding the teachers in projecting the PPT. According to the invention, various operation gestures during the projection of the PPT and corresponding methods are integrated into the ring which can be conveniently worn, a series of PPT operation in classes of the teachers, such as writing characters on the PPT, red-light projection, PPT switching and the like can be completed simply through corresponding finger control, such that classroom operation of the teachers is facilitated. The PPT operation comprises PPT switching operation, PPT writing character operation and PPT red-light projection operation.
Description
Technical field
The present invention relates to a kind of projection equipment, specifically relates to a kind of PPT projecting device aiming at teacher's design.
Background technology
PPT(power point) be one of maximum software in teaching, due to the operability of this software and illustrative stronger, be requisite application software in school classroom.But need to utilize mouse to operate in teacher's process at school, the demonstration of control PPT, due to the restriction of mouse, so just limit the action of teacher, make it only teach near lectern, can not go in the middle of student and carry out classroom interaction with it.The support of Bluetooth technology, carries out the exchange of wireless messages between the peripheral hardware be connected with computer by ring.Ruddiness radiation technique, adopt quantum well LD to make light source, export the visible red laser of human eye, its penetration power is strong, and on-line stage is applied to student classroom guided teaching already.Sensor technology, this device is integrated with pressure transducer, pulling by human muscle, as hand muscle by pressure-controlled, thus send corresponding order, carry out PPT projection operation.
There are some multi-functional telepilots on the market at present, the such as patent No. is 200720119493.6 disclose a kind of Multi-functional multi-media remote controller, but the many uses of control panel button of this part patent are more loaded down with trivial details, and human-computer interaction interface is stiff, are not very vivid; The patent No. be 200920043086.0 patent discloses a kind of PPT Pen for turning page, this part patent is only provided with a Telescopic pointer on a remote control, distinguishes not quite with traditional controller.
In a word, the PPT Pen for turning page sold in the market, circuit structure is complicated, and volume is comparatively large, and carry inconvenience, some buttons are many, and use more loaded down with trivial details, human-computer interaction interface is stiff, are not very vivid.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, provide one more easily, Wearable, aim at the PPT projecting device of teacher's design.
In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions:
Apparatus of the present invention mainly comprise two compositions: primarily of lasso 1, red light emitting device 2, form with the Bluetooth connection device 3 that is connected of projection computer, it is characterized in that: this ring has a lasso conveniently worn 1, lasso 1 is integrated with pressure transducer, controls to show PPT by the pressure transducer controlled on lasso 1.The Bluetooth connection device 3 that ring is connected with projection computer simultaneously supports the use.Two parts combine, and assisted teacher carries out PPT projection.
The various operating gesture of projection PPT and correlation method are integrated on a ring being convenient to wear by the present invention, by a series of PPT operations on teacher classroom, as write hornbook book, ruddiness projection, PPT switching etc. on PPT, only need by pointing control accordingly, can complete, be convenient to the classroom operation of teacher.
(1) PPT blocked operation: operator only by flexing one's fingers, need touch the pressure transducer 1 be installed on ring, by the Signal transmissions of sensor, by Signal transmissions on the computer being connected with message exchange 3, thus carries out PPT switching.
(2) PPT writing words operation: operator waits operation to switch ring by flexing one's fingers and manipulates the using forestland of PPT, ring is switched to " PPT write mode ", simultaneously, the red light emitting device 2 of ring sends a branch of ruddiness location, operator only need by controlling the position of ring on projecting apparatus screen, by the paddling of finger on the projecting apparatus screen of correspondence, complete character calligraph.
(3) PPT ruddiness projection operation: operator by the long pressure transducer by controlling ring, thus touches " the ruddiness projection mode " of ring.Now, ring sends ruddiness, carries out mark operation to the content on PPT.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention provides one more easily, the PPT projecting device of Wearable for teacher.Comparatively comfortable teaching equipment is provided when making teacher at school.
Accompanying drawing explanation
Fig. 1 is a kind of PPT projecting device structural drawing aiming at teacher's design
Fig. 2 is that the PPT projecting device of a kind of teacher of aiming at design is connected composition.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail:
Apparatus of the present invention mainly comprise two compositions: primarily of lasso 1, red light emitting device 2, form with the Bluetooth connection device 3 that is connected of projection computer, it is characterized in that: this ring has a lasso conveniently worn 1, lasso 1 is integrated with pressure transducer, controls to show PPT by the pressure transducer controlled on lasso 1.The Bluetooth connection device 3 that ring is connected with projection computer simultaneously supports the use.Two parts combine, and assisted teacher carries out PPT projection.
The various operating gesture of projection PPT and correlation method are integrated on a ring being convenient to wear by the present invention, by a series of PPT operations on teacher classroom, as write hornbook book, ruddiness projection, PPT switching etc. on PPT, only need by pointing control accordingly, can complete, be convenient to the classroom operation of teacher.
(1) PPT blocked operation: operator only by flexing one's fingers, need touch the pressure transducer 1 be installed on ring, by the Signal transmissions of sensor, by Signal transmissions on the computer being connected with message exchange 3, thus carries out PPT switching.
(2) PPT writing words operation: operator waits operation to switch ring by flexing one's fingers and manipulates the using forestland of PPT, ring is switched to " PPT write mode ", simultaneously, the red light emitting device 2 of ring sends a branch of ruddiness location, operator only need by controlling the position of ring on projecting apparatus screen, by the paddling of finger on the projecting apparatus screen of correspondence, complete character calligraph.
(3) PPT ruddiness projection operation: operator by the long pressure transducer by controlling ring, thus touches " the ruddiness projection mode " of ring.Now, ring sends ruddiness, carries out mark operation to the content on PPT.
The undeclared part related in the present invention is same as the prior art or adopt prior art to be realized.
