Embodiment two

Fig. 2 a is the flow chart that a kind of key message provided by Embodiment 2 of the present invention determines method, the embodiment of the present invention with It is optimized based on above-described embodiment, in the present embodiment, further will be responsive to receive acts on current display page Touch operation on face specifically optimizes are as follows: determines the associated gesture of touch operation acted in current display page received Type, the touch mark of the corresponding gesture-type of display.

For above-mentioned optimization, instructor, can be when needing to carry out key content explanation, in intelligent friendship during giving lessons It is touched in the current display page of mutual plate, in the present embodiment, it is believed that intelligent tutoring plate has touch operation Monitor function, the present embodiment is it is possible thereby to receive and respond the touch operation of generation.

Meanwhile the present embodiment can be by identifying the received associated gesture-type of touch operation, to further determine that this Which gesture-type specifically corresponded to and touched mark, and can determine that each touch mark has been specifically identified in the explained content of instructor Which emphasis mark.

Specifically, the present embodiment can determine the touch by the analysis to the received touch operation of intelligent tutoring platform Operation which kind of gesture-type be specifically associated with, illustratively, the present embodiment can by analyze every time receive touch operation when Between be spaced and alternate position spike and listen to the time interval and alternate position spike pressed event and lift event to form touch operation, should Determine whether gesture when user generates touch operation is percussion etc.；In addition, this step can also by receive touch behaviour Whether the temporary shape of the touch track of work is analyzed, be setting-out or picture come gesture when determining that user generates touch operation Circle etc..

In addition, the present embodiment further acts on current display page to what determination received on the basis of above-mentioned optimization The touch mark of the associated gesture-type of touch operation on face, the corresponding gesture-type of display is specifically optimized, and is had Body can be multiple angles such as to tap, draw a circle and draw lines to optimize from gesture-type.

As shown in Figure 2 a, a kind of key message provided by Embodiment 2 of the present invention determines method, specifically includes following operation:

It should be noted that the present embodiment two specifically provides instructor during giving lessons using the gesture counterweight tapped Key message determination process when point explanation content is labeled.Firstly, the S201 to S203 of the present embodiment have been described in detail why Sample determines that the received associated gesture-type of touch operation is the realization process tapped.

S201, when listen to including once touch the event of pressing and it is primary touch lift the composition of matter of event when, determine Receive a touch operation.

In the present embodiment, it is believed that intelligent tutoring plate has the monitor function of each touch event in touch operation, by This can specifically monitor touch event of the user on intelligent tutoring plate, and the present embodiment can listen to one group of user The touch event of generation, if including once touching event of pressing and primary touch to lift event in this group of touch event, so that it may Think that user has carried out a touch operation on intelligent tutoring plate, this step can receive each touch behaviour of user's generation Make.

If receiving at least touch operation three times in S202, set period of time, the touch letter of each touch operation is obtained Breath.

When carrying out touch operation reception based on S201, the receiving time of each touch operation can be monitored, to sentence It is fixed whether to receive at least touch operation three times in the set time period, wherein the occurrence of the set period of time can be based on Practical application actual set, and the receiving time of a touch operation can be recorded by the generation time for touching event of pressing, It can also be recorded by the generation time for touching event of lifting.

It is identified as click for the touch behaviour that difference user acts on intelligent tutoring plate, double-clicks or taps, this implementation Example setting only receives at least touch operation three times in the set time period, just thinks to meet the primitive decision tapped, as a result, When receiving at least touch operation three times in set period of time, the subsequent judgement whether touch operation identifies percussion is just carried out, Otherwise, can directly determine the associated gesture-type of touch operation not is to tap.

In the present embodiment, the touch information specifically can refer to time and the attribute as position produced by indicating touch operation (generation time of each touch event in such as composition of matter, for another example each touch event acts on the work on intelligent tutoring plate to information With position etc.), touch information can accordingly be generated when composition of matter acts on intelligent tutoring plate, this step can directly acquire To the touch information of touch operation.

If the touch information of S203, each touch operation, which are all satisfied the first decision condition and adjacent two touch operation, meets the Two decision conditions, it is determined that at least the associated gesture-type of touch operation is to tap three times.

The present embodiment can consider that the touch information of received each touch operation in the set time period meets first and determines After meeting the second decision condition between condition and adjacent two touch operation, at least three acted on intelligent tutoring blank are just determined The secondary associated gesture-type of touch operation is to tap；Otherwise, it is believed that gesture-type is not percussion, can terminate the present embodiment at this time Subsequent operation.

Further, the touch information of the touch operation includes: the first generation time and first for touching event of pressing It generates position and touches the second generation time of event of lifting and second and generate position；

First decision condition are as follows: the difference of the second generation time and corresponding first generation time is less than first time threshold The alternate position spike that value and the second generation position generate position with first is less than first distance threshold value；

Second decision condition are as follows: the time difference of latter touch operation and previous touch operation is less than second time threshold And the range difference of latter touch operation and previous touch operation is less than second distance threshold value.

It is generated in position in abscissa difference or ordinate difference it is understood that the alternate position spike specifically may is that Maximum value；The time difference specifically can refer to: the first generation time of two touch operations is poor or the second generation time is poor, again Alternatively, the difference of the first generation time of latter touch operation and the second generation time of previous touch operation；The range difference Specifically can refer to: the first of latter touch operation generates the difference of the first generation position of position and previous touch operation.

In addition, the determination process and the natural gesture operation of instructor in order to make key message are more agreed with, sheet is being executed Before embodiment, technical staff first samples the touch operation data in instructor's field research, to first time threshold Value, first distance threshold value, second time threshold and second distance threshold value carry out test training, thus to obtain practical behaviour is more met The value range of work, e.g., first time threshold and second time threshold preferable value in the range of 0.5s~1s, first Distance threshold preferably preferably exists in 2cm~5cm or value in the range of 16 pixels~30 pixel, second distance threshold value Value in the range of 5cm~8cm.

S204, when determining the gesture-type to tap, will the corresponding touch point of each touch operation as touch mark Know display.

In the present embodiment, when gesture-type be tap when, it is believed that the corresponding touch point of touch operation be it is discrete, often Touch area that a touch point can be sized on a display screen with one shows that the present embodiment will show screen display Each touch point as tapping operation when corresponding touch mark.

It should be noted that the operation of the present embodiment following S205 to S211, describes gesture-type to tap when progress The specific implementation process that key message determines.

S205, based at least touch operation is respectively acting on the position in current display page three times, form a circle Shape region is as hit area.

Specifically, can will in touch operation touch press event or touch lift the corresponding generation position of event as Position of the touch operation in current display page.Illustratively, the generation of event is pressed due to touching in touch operation Position can most indicate the initial intention position of user's operation, and the present embodiment will preferably touch the production for event of pressing in each touch operation Raw position is as the position in current display page.

After the position for determining each touch operation, the circumscribed circle comprising each position can be formed, the present embodiment will The corresponding border circular areas of the circumscribed circle is determined as hit area, and the area size of the hit area can pass through the radius of the circumscribed circle Size determines.

S206, the association rectangle for obtaining each element in current display page.

Specifically, for each element in current display page, in edit phase correspondence, there are a rectangle conducts Editing frame, it is believed that each element its bottom of editor in current display page is using a rectangle as support, and one Element corresponds to a rectangle, and the rectangular information of the rectangle has been generated when carrying out element editor, the present embodiment remember the square Shape is association rectangle, this step can directly acquire the rectangular information of the association rectangle of each element, may include in rectangular information The coordinate value in the rectangle upper left corner, length and width of rectangle etc. are used to identify the attribute information of rectangle.

It should be noted that the association rectangle can be the boundary rectangle of corresponding element, it is also possible to length and is wider than this The setting rectangle of boundary rectangle, setting rectangle can be regarded as on the basis of corresponding boundary rectangle, increase separately to the length and width of rectangle The rectangle of certain back gauge value, the present embodiment is preferably using setting rectangle as association rectangle, to guarantee based on hit area and close Join hit accuracy when rectangle carries out element hit.

S207, there are Chong Die overlapping associations rectangles with hit area for lookup from each association rectangle.

In the present embodiment, the rectangular information of each association rectangle can be passed through, it is determined whether exist Chong Die with hit area Association rectangle, and the association rectangle for meeting overlay condition can be denoted as overlapping associations rectangle, wherein the overlapping in the present embodiment May include following several situations: the corresponding region of association rectangle contains hit area, alternatively, the corresponding region of association rectangle Included in hit area, alternatively, the corresponding region of association rectangle is intersected with the partial region of hit area.

S208, the corresponding element of each overlapping associations rectangle is added in element set with setting adding conditional.

In the present embodiment, it after determining each overlapping associations rectangle, is equivalent to the corresponding element of overlapping associations rectangle and is hit Region hit, this step can further determine whether the element meets setting adding conditional, if meeting, which is added to In element set, wherein the setting adding conditional may is that the element not yet adds in element set.

S209, determine whether the element total quantity in element set changes, if so, executing S210；If it is not, then holding Row S211.

In the present embodiment, it is believed that element set is initially empty, after the element determined is added to element set, The element total quantity for including may change, at this point, S210 can be continued to execute, but constantly holding with element hit operation Row, may be not present the element for meeting adding conditional, and hereafter, the element total quantity in element set will remain unchanged, this When can further execute S211.

S210, using each overlapping associations rectangle as hit area, return and execute S207.

It, specifically, can be by the above-mentioned each overlapping determined when determining that element total quantity changes in the present embodiment Rectangle is associated with as hit area, S206 is returned and continues the search operation that iteration executes element hit.

S211, the element in element set is determined as key message and is stored.

In the present embodiment, when the element total quantity for determining element set is no longer changed, show all possible hits Element determined by lookup, at this time can be using each element being added in element set as key message, and with each The original correlation of element is stored.It is understood that can be screened to element before being stored, with screening The content of courses that instructor temporarily adds during giving lessons out.

S212, the edit operation for acting on target critical information in response to receiving, display include the target critical The edit page of information.

Illustratively, the present embodiment can edit the key message of formation, specifically, can receive user couple After carrying out edit operation triggering as the either element of target critical information in element set, responds the edit operation and form one A edit page for being associated with the target critical information, user can edit target critical information in the edit page.

S213, receive editor complete instruction when, save the edit page.

It is understood that life can be triggered after user completes the editor of target critical information in edit page Instruction is completed at editor, this step, which is based on the editor, which completes instruction, can save edited edit page.

On the basis of above-described embodiment, Fig. 2 b gives the example that gesture associated element is determined in the embodiment of the present invention two Figure, as shown in Figure 2 b, contains the element of text type and the element of graph style etc. in current display page 20, based on upper Corresponding associated element determines step when stating gesture-type to tap, can be by border circular areas 21 as initial hit area, together When available current display page 20 in shown each element association rectangle, as being showing content with " here it is texts " The corresponding first association rectangle 22 of text box (element), the corresponding second association rectangle 23 of line segment and the corresponding third of curve are closed Join (the association rectangles that all elements are not shown in the figure) such as rectangles 24.

It can be described as being associated the operation that element determines as initial hit area from border circular areas 21: from obtaining Each element association rectangle in can find the association rectangle Chong Die with border circular areas 21 and have the first association rectangle 22 and the Two association rectangles 23；Thus the corresponding element of rectangle 22 (text box and it includes content) can be associated with by first to be associated with second Element is arrived in 23 corresponding element (line segment) of rectangle addition (element set is sky at this time, i.e., there is no the above-mentioned elements determined) In set, element total quantity is 2 at this time, is changed, can continue to execute lookup；As a result, rectangle can be associated with by first respectively 22 are associated with rectangle 23 as new hit area with second, and can find with the first Chong Die association rectangle of association rectangle 22 is the Three association rectangles 24, may further look for the association rectangle Chong Die with the second association rectangle 23 is also third association rectangle 24, and can Determine that the third association corresponding element of rectangle 24 is curve, and curve not yet adds in element set, thus can add curve It is added in element set, element total quantity is 3 at this time, is changed, can equally continue to execute lookup；Therefore, so that it may by For three association rectangles 24 as new hit area, can find the association rectangle Chong Die with third association rectangle 24 has the first association Rectangle 22 is associated with rectangle 23 with second, and because the first association corresponding text box of rectangle 22 and the second association rectangle 23 are corresponding Line segment is existing to be will not be repeated again addition, at this point, element sum quantity is still 3, does not change with element set, is met Termination condition is searched, can terminate to search.It is determined when finally determining instructor's percussion border circular areas 21 based on above-mentioned lookup Key message by text box and its include content, line segment and curve.

Embodiment three

Fig. 3 a is the flow chart that a kind of key message provided by Embodiment 2 of the present invention determines method, the embodiment of the present invention with It is optimized based on above-described embodiment one and embodiment two, as shown in Figure 3a, a kind of key that the embodiment of the present invention three provides Information determines method, specifically includes following operation:

It should be noted that the present embodiment three specifically provides instructor during giving lessons using the gesture counterweight drawn a circle Key message determination process when point explanation content is labeled.Firstly, the S301 to S303 of the present embodiment have been described in detail why Sample determines that the received associated gesture-type of touch operation is the realization process drawn a circle.

S301, sampling touch operation corresponding all touch points in current display page, and obtain and be based on each institute State the touch track of touch point formation.

In the present embodiment, for the intelligent tutoring plate for having touch event monitor function, this step can be supervised Hear the touch operation for acting on current display page, wherein it is believed that current display page is showed by intelligent tutoring plate, Its touch operation can be pressed event by touch, touch and lift event and a series of touchings between above-mentioned two touch event Moving event composition is touched, meanwhile, this step can determine that each touch event exists by the monitoring to a series of above-mentioned touch events Corresponding touch point in current display page, the corresponding touch track of touch operation can be formed by being based ultimately upon a series of touch points, This step can obtain and be formed by touch track.

In the present embodiment, it can carry out sequential sampling according to the generation time of touch event each in touch operation and respectively touch Event corresponding touch point in current display page, to obtain the coordinate information of each touch point.It is understood that being formed In one group of touch event of touch operation, first touch event is equivalent to touch and presses event, and corresponding touch point can be denoted as Starting point is touched, the last one touch event is equivalent to touch and lifts event, and corresponding touch point can be denoted as touch terminating point, And touch moving event, corresponding touching are then equivalent in remaining touch event for touching event of pressing and touching event of lifting Touch transfer point can be a little denoted as by touching.For a touch operation, there must be in composition of matter has touch to press event Event is lifted with touch, but can be there is no moving event is touched, this kind of situation is equivalent to the touch operation to a location point.

S302, according to each touch point, determine whether the touch track includes to enclose shape track and the circle number that includes is No satisfaction imposes a condition.

In the present embodiment, position of each touch point needed for constituting touch track in current display page can be obtained to sit Mark, by the position coordinates of each touch point, can determine in touch track whether present by the circle shape decision rule of setting Shape track is enclosed, and can determine that the circle number that circle shape track is presented.Illustratively, this step can be sat according to the position of touch point Mark, determines the distance value of each touch point and specified coordinate point, then by each distance value and set distance threshold value comparison, if there is Enclose shape track, then the distance value for needing continuous touch point is less than set distance threshold value, and it is subsequent have a touch point away from It is greater than set distance threshold value from value.

It should be noted that can first analyze the characteristics of circle shape track, find for the judgement for realizing circle shape track It is mainly characterized in that the line of one group of touch point can form the closing an of arc or close to closed curve, if with wherein one A touch point be the center of circle, using setting value be radius draw circle, then the distance value that can have some touch points to the center of circle first be less than or Equal to radius, these touch points are equivalent to the inside in drawn circle, and there is also the distances of a part of touch point to the center of circle later Value is greater than radius, these touch points are equivalent to the outside in drawn circle, then can also have some points and be in drawn circle again It is internal.

Based on These characteristics, the present embodiment sets the realization operation that following circle shapes determine, specifically, Fig. 3 b gives this The implementation flow chart that touch track circle shape determines is carried out in inventive embodiments three, it is optionally, described according to each touch point, really The fixed touch track whether include to enclose shape track and the circle number that includes whether meet setting condition can be by as shown in Figure 3b Mode realize that as shown in Figure 3b, which specifically includes:

S3021, judgement distance value of each touch point to the distance value for setting datum mark, as each touch point is determined.

It is primarily based on this step and determines each touch point to the distance value for setting datum mark, according to foregoing description, the setting base It is equivalent to the center of circle of drawn circle on schedule, which can preferably choose from touch point, and be generally preferred to touch Initial point.Therefore, this step is equivalent to the distance value for determining each touch point to touch starting point, using the judgement as each touch point away from From value.

S3022, the judgement distance value for successively choosing touch point are compared with third distance threshold.

This step is equivalent to since the judgement distance value for touching starting point, then by successively choosing subsequent touch clockwise The judgement distance value of point, and each judgement distance value of selection can be compared with third distance threshold, and record ratio in real time To result, wherein according to the above-mentioned description to drawn circle, the practical radius for being equivalent to drawn circle of the third distance threshold, and should The setting of third distance threshold also corresponds to an empirical value, and the test that can first pass through different values in advance compares, and determines and determines effect The optimal value of fruit is as third distance threshold.

S3023, when the judgement distance value that there is setting continuous quantity touch point is greater than third distance threshold, determining subsequent is It is no that there are the judgement distance values of a target touch point to be less than or equal to the third distance threshold.

This step can be according to the comparison result of above-mentioned record, it may be determined whether sentences setting continuous quantity touch point Set a distance value is greater than third distance threshold, and judgement at this time is actually equivalent at the touch point for determining whether there is setting continuous quantity In the outside of drawn circle, the setting continuous quantity is also an empirical value, selected also according to test training.If above-mentioned judgement It sets up, then can further determine that the subsequent judgement distance value that whether there is a target touch point is less than or equal to third apart from threshold Value, judgements at this time be actually equivalent to there are continuous set amount in it is drawn it is round outside touch point after, it is subsequent whether to deposit Following S3024 can be performed if the judgement is set up a touch point inside drawn circle.

It should be noted that if two in this step to be determined with one invalid, it is believed that in touch track not Comprising enclosing shape track.

S3024, if it exists, it is determined that the touch track includes circle shape track, will add 1 comprising enclosing the circle number of shape track, And return and execute S3023, until the corresponding touch point of currently selected judgement distance value is touch terminating point.

The decision condition that this step is equivalent to above-mentioned S3023 is set up, at this time, it may be determined that the formed touch track of touch operation In contain circle shape track, and can will add 1 comprising the circle number for enclosing shape track, subsequent may further determine that selected when realizing above-mentioned judgement is sentenced Whether the corresponding touch point of set a distance value is to touch terminating point, if not touching terminating point, then can execute the circle shape of S3023 again Decision, to determine whether the touch point behind target touch point can also re-form circle shape track；If terminating point is touched, then may be used Execute following step.

S3025, if it is determined that circle number be greater than or equal to setting value, it is determined that the circle number meets setting condition.

Based on the operation of above-mentioned S3024, in addition to determining and containing circle shape track in touch track, it may further determine that and included Specific circle number, when the specific circle numerical value determined is greater than or equal to setting value, so that it may think that enclosing number satisfaction imposes a condition, In, the setting value is preferably 2, that is, the circle number for the circle shape track that touch track includes needs to be greater than or equal to two Circle, but when setting value takes 1, is equally applicable, i.e., it is also contemplated that when touch track includes a circle circle shape track, it is also contemplated that should The associated gesture-type of touch operation is to draw a circle.

It is that the exemplary diagram drawn a circle currently shows page as shown in Figure 3c that Fig. 3 c, which gives the associated gesture-type of touch operation, The touch track 31 of received touch operation is shown in face 30, it, can be true by the judgement of above-mentioned the provided determination flow of Fig. 3 b Determine to contain circle shape track in touch track 31, and include that enclose the circle number of shape track be 1 circle (there is no formed completely for the 2nd circle), Thus it can determine that form the associated gesture-type of the touch operation of touch track 31 is to draw a circle.

S303, when the touch track include circle shape track and comprising circle number meet impose a condition when, determine the touch grasp Making associated gesture-type is to draw a circle.

Above-mentioned S302 and its spread step have implemented whether touch track includes whether circle shape track and circle number are full The determination to impose a condition enough, in this step when above-mentioned two condition meets simultaneously, so that it may think that received touch operation is associated Gesture-type is to draw a circle；Otherwise it is believed that gesture-type is not to draw a circle, the subsequent operation of this implementation can be terminated at this time.

S304, determine that the gesture-type is when drawing a circle, to mark the corresponding touch track of the touch operation as touch Know display.
