Description
Technical field
The present invention relates to a kind of interactive electric whiteboard, specifically relates to a kind of interactive electric whiteboard based on body sense technology.
Background technology
Present Informalized teaching has penetrated in the middle of daily teaching gradually, and electronic whiteboard will be widely used in basic education field.Interactive electric whiteboard is by electronic induction blank, induction pen, computing machine, blank operating system software and projector, and it can carry out information communication with computer.Electronic whiteboard is connected on computing machine, utilizes projector by the content projection on computing machine on the screen of electronic whiteboard, utilize specific induction pen can at the enterprising line operate of blank, can working procedure, editing files.Electronic whiteboard universal, the dust produced with chalk when can reduce teacher's writing on the blackboard, to the injury of health, shortens the writing on the blackboard time, more environmental protection.The advantage of electronic whiteboard has: (1), relative to the one-way fashion of conventional projectors, uses interactive electronic white board to make course more interactive; (2) teacher is made to be absorbed in classroom, instead of the technical problem such as process computer or projector; (3) by the software of electronic whiteboard, utilize software records function, make teaching interim or impromptu on classroom also be able to record; (4) entertaining in classroom is increased.
But comprehensive present stage electronic whiteboard applicable cases, also there are some problems in electronic whiteboard: (1) price costly: the clean and maintenance problem of (2) blank; (3) touch sensitive plate arbitrarily cannot be responded to write freely and easily in use, need back to student, the successes achieved in teaching instantly cannot be learnt; (4) should not use in the place of electric power supply instability.
Body sense technology is a kind of device or environment interaction that directly can utilize the modes such as body action, sound, Rotation of eyeball and periphery, and without the need to using the human-computer interaction technology of other opertaing devices.Eliminate the communication way of conventional keys, operating rod, slide-mouse etc. and computer, change with intuition, the mode that meets limbs reflection or daily life operation to carry out interaction with multimedia.The Leap 3D of the Kinect of Microsoft, Leap Motion company is exactly two main brands in current body sense input field, under the prerequisite of operator without the need to hand-held any induction stage property, is caught by camera and sensor, the action of identifying operation person.Body sense technology is replacing complicated control system in very many fields, becomes the pioneer of man-machine interaction of new generation.All there is very good application prospect in such as high precision operation, high-risk construction, underground work etc. field.But body sense technology is not also applied to educational system aspect.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, provide a kind of without the need to relying on the fixing input equipments such as conventional keyboard, mouse, touch pad, also without the need to hand-held any sensing stage property, only need to carry out function screen by some simple gestures in body sense spatial dimension and just can control various application program and writing on the blackboard on electronic whiteboard, teacher can be faced directly student, realize better interactive electronic whiteboard.
In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions:
Based on an interactive electric whiteboard for body sense technology, comprising: based on the gesture recognition system of body sense technology; Based on the hand-written character input method of body sense technology.
Gesture recognition system based on body sense technology comprises:
(1) packet of gesture is defined, as: expression of clenching fist is clicked;
(2) Kinect attitude sensing input equipment;
(3) gesture recognition module: by traversal buffer data, identify palm position and actuation time interval and detect the direction of each point one by one, displacement, mistiming whether meet the requirements to judge gesture whether with meeting in packet;
(4) interactive electronic plate: electronic induction blank, computing machine, blank operating system software and projector.
Hand-written character input method based on body sense technology comprises:
(1) literal pool comprising the track of each word is set;
(2) an individual sense equipment is set;
(3) input state of identifying operation person, it comprises the following steps:
S11: the hand of operator stretches out expression to text box locality and starts writing, the text box on contact electronic whiteboard;
S12: the hand of operator is regained expression in the other direction and lifted pen to text box position, leave text box;
(4) operator starts writing and carries out hand-written, meanwhile, shows the position of operator's hand over the display and starts writing or lift the state of pen;
(5) body sense equipment judges single character end of input by the pause of operator;
(6), after a hand-written complete word, computing machine senses by body sense equipment the track that operator streaks in text box;
(7) in computing machine track operator marked and the literal pool that prestores, the track of each word carries out characteristic matching;
(8) each candidate character is listed in word candidate bar from high to low according to matching degree;
(9) candidate character that operator's selective recognition is correct.
Compared with prior art, the invention has the beneficial effects as follows:
Without the need to relying on the fixing input equipments such as conventional keyboard, mouse, touch pad, also without the need to hand-held any sensing stage property, only need to carry out function screen by some simple gestures in body sense spatial dimension and just can control various application program and writing on the blackboard on electronic whiteboard, teacher is allowed to face student directly, impart knowledge to students more flexible, teachers and students above and below the stage interaction are closer, improve the participation of student classroom, promote learning efficiency.
