A gesture instruction set is preset, the tracks of the finger actions of a speaker are compared with gesture figures in the instruction set, if the tracks of the finger actions of the speaker are matched with the gesture figures in the instruction set, the fact that the speaker gives out corresponding instructions is confirmed, and the instructions are responded to control the display frames of the display big wall. When specific implementation is carried out, the speaker only needs to wear a collection device with the size of a fingernail on a finger and does not need to get close to the display big wall and hold any equipment, the two hands and the body of the speaker can be released, and the speaker can through himself into a lecture.

Description

Show gesture opertaing device and the method for big-wall
Technical field
The present invention relates to combination display technique field, particularly relate to a kind of gesture opertaing device and method that shows big-wall.
Background technology
In the time that people use splicing big-wall or large-sized electronic whiteboard to carry out PPT demonstration, speaker need to do some shirtsleeve operations, as the page turning of PPT, and the focusing of courseware, the switching of file, the convergent-divergent of image, even shows the operations such as wall signal switching.
Conventionally, people assist complete operation with equipment such as desktop computer, notebook, dull and stereotyped electroplax, mobile phone, laser pen, writing pencil, motion captures.But these equipment operatings have certain limitation, as desktop computer and notebook, speaker need to stand in or the equipment side of being sitting in operates; As panel computer and mobile phone, speaker must one hand or both hands handheld device operate; As laser pen, speaker must handheld device operate; As writing pencil, speaker must write on electronic whiteboard.In the time that electronic whiteboard is also high than speaker, speaker cannot simply complete and the operation such as write; As motion capture equipment, speaker will put your hands up and start and operation, and controllable precision is poor, and inconvenient operation with infrared the same, and can not have other thing to stop between equipment.
It seems generally, above-mentioned these operating equipments have limited speaker's both hands or health, have weakened speaker's body language.When operation, speaker's use equipment that distracts attention, makes speech repeatedly occur of short duration interruption.
Summary of the invention
Based on above-mentioned situation, the present invention proposes a kind of gesture opertaing device and method that shows big-wall, to show the display effect of big-wall according to speaker's gesture control.For this reason, the scheme of employing is as follows.
Show a gesture opertaing device for big-wall,
Comprise the finger Wearable device being fixed on speaker's finger and be positioned at the computer end on computer;

Described finger Wearable device as shown in Figure 2, is fixed on speaker and points, and its profile can be the form of fingerstall, can be also the form of finger ring, and its volume can be accomplished thumbnail, thereby is unlikely to speaker to cause burden.Its inside comprises 3-axis acceleration sensor, three axle geomagnetic sensors and wireless transmission end, can also comprise a small-sized button cell or lithium battery.Described computer end comprises wireless interface receiving end and data processing unit, wireless interface receiving end adopts as the receiving end of current wireless mouse, carry out data transmission by bluetooth or 2.4GHz wireless technology, transmission range can reach 8-20 rice, and data processing unit is built in computer.
Described 3-axis acceleration sensor is for gathering the acceleration of speaker's finger movement, described three axle geomagnetic sensors are for gathering the dimensional orientation of finger, described acceleration and dimensional orientation are sent to described wireless interface receiving end by described wireless transmission end, described wireless interface receiving end is forwarded to described data processing unit, described data processing unit simulates the track of speaker's finger movement according to described acceleration and dimensional orientation, by the track simulating and the concentrated graphic correlation of predetermined instruction, determine the figure of coupling, the instruction control corresponding according to coupling figure shows big-wall.
Introduce the workflow of this equipment below.
Step 1: speaker is the corresponding relation of gesture and instruction in learning gesture instruction set in advance, represents to click PPT as finger draws a semicircle, draws a circle, represents to double-click PPT etc.
Step 2: speaker brings the finger Wearable device of this equipment, and flicking switch, opens this equipment.
Step 3: speaker according to demand, with finger than marking a figure;
Step 4: both started to gather speaker's finger movement after the start of finger Wearable device, and action data is radioed to computer end, until receive shutdown command.
Step 5: computer end is received after data, data are carried out to analytical calculation, simulate the movement locus of finger, by track and the concentrated graphic correlation of gesture instruction, find coupling figure, determine corresponding instruction according to coupling figure, the instruction that this instruction is sent as speaker, and then respond this instruction.
