In a preferred embodiment of the present application, can obtain by following steps the parameter of described contact area:
Steps A 1, obtain the peripheral coordinate points of described contact area;
For example, for the determined contact area of step 202, can at first carry out discretize to it, be decomposed into the point of various discrete, then, find to be positioned at outermost discrete point in the contact area, also be peripheral coordinate points.
Steps A 2, by connecting all or part of described peripheral coordinate points, produce the profile of described contact area;
Steps A 3, according to the profile of described contact area, determine the shape of described contact area;
For the touch apparatus of single face touch screen, place contact (thumb contact) is only arranged usually, therefore can connect all or part of described peripheral coordinate points to form the profile of a contact area by straight line.Take application scenarios 1 as example, the left hand thumb forms the profile of a contact area at mobile phone front touch screen, and can determine the sub-elliptical type that is shaped as of this contact area.
In particular cases, have two contact areas that the contact of two places forms.Take application scenarios 2 as example, left hand forms the profile of the contact area of a sub-elliptical type in the left side of panel computer touch screen, and simultaneously, right finger also forms the profile of the contact area of a sub-elliptical type on the right side.
And for the touch apparatus of two-sided and/or two-sided and side touch screen with have the touch apparatus of back side touch screen, often has the many places contact, therefore can connect all or part of described peripheral coordinate points to form the profile of a plurality of contact areas by straight line, and can further obtain the shape of each contact area, such as E type, bar shaped or rectangle etc.
Certainly, except straight line connects, can also connect all or part of described peripheral coordinate points to form the profile of contact area by curve, do not limited at this,
The profile of steps A 4, the described contact area of foundation obtains the trend of described contact area with respect to the direction of reference point;
In specific implementation, can set up the frame of reference, horizontal ordinate is x, ordinate is y, so, can true origin (0,0) as reference point.With reference to Fig. 3, show the schematic diagram of the frame of reference and contact area on 1 time mobile phone of application scenarios, it is true origin (0 take the upper left corner on mobile phone, 0), the y axle is down, elliptic region among the figure represents the contact area that the left hand thumb forms at mobile phone front touch screen, then can represent with the angle α of the major axis of this elliptic region or minor axis and x axle the trend of this elliptic region.
Certainly, the method for the above-mentioned trend of obtaining described contact area and the description of trend are just as example, and those skilled in the art can adopt any means to obtain and describe described trend, and the application is not limited this.
Steps A 5, according to the central point of the profile of the described contact area position with respect to reference point, obtain the distribution of described contact area.
If a plurality of contact areas are arranged, this step then need be obtained respectively central point with respect to the position of true origin (0,0).
When the canonical parameter with the contact area of the parameter of described contact area and certain specific gripping state compares, if adopt a plurality of parameters, can compare separately.Suppose to have adopted shape and move towards two parameters, when then the corresponding comparative result of shape and trend is all in preset range, can judge that user's gripping state is this specific gripping state.
At vpg connection, can compare the registration (perhaps misalignment) of two shapes.Take the contact shape of thumb as example, in practice, if gather the contact data of user under various gripping states, thereby preset the canonical parameter of the contact area of specific gripping state; What then compare is the registration of identical thumb, at this moment, the registration threshold value setting can be got larger, such as 95%.And if canonical parameter is according to the contact data initialization of non-user under various gripping states, owing to the shape of different thumbs has difference, thus less registration threshold value can be set, such as 80% etc.Normally, if the registration of the two, is then thought comparative result greater than the registration threshold value in preset range, the misalignment of the two is less than the misalignment threshold value, then think comparative result in preset range, the application is not limited concrete setting and the concrete numerical value of registration or misalignment.
Aspect moving towards, can preset the standard angle scope of the contact area of specific gripping state according to the sample data that gathers, if with the trend of described contact area in this standard angle scope, think that then comparative result is in preset range.
Take application scenarios 1 as example, identical left hand thumb is identical at the touch shape that touch-screen forms, and still, each grip position difference has determined trend and distributed to change simultaneously.Therefore actual specific than the time, can also and distribute as a pair of parameter trend, jointly compare.
For application scenarios 1, suppose that the left hand thumb in the parameter of the contact area that mobile phone front touch screen forms all grips the preset range of the standard trend of contact area of state and shape leftward, can judge that then the user is in the left-handed state.For application scenarios 2, although the right-hand man forms a contact area at panel computer respectively, but, because the parameter of the contact area that left hand forms in the left side of panel computer touch screen grips in the preset range of canonical parameter of contact area of state, therefore can judge that also this user is in the left-handed state leftward.
Above comparison procedure to shape, trend and three parameters of distribution illustrates, and is appreciated that the application's comparative approach is not limited to above-mentioned example.And the application's parameter also is not limited to above-mentioned three parameters, and the application is not limited concrete parameter and concrete comparison procedure.
The application judges based on the physiological property of staff which kind of gripping state described contact area belongs to according to the parameter of described contact area.The application only provides the canonical parameter of contact area of certain specific gripping state of three kinds of touch apparatus, in fact, those skilled in the art can also be according to the size shape of the physiological property of staff, touch apparatus and handling characteristics, user's use habit, preset the canonical parameter of contact area of certain specific gripping state of other touch apparatus, the application is not limited the canonical parameter of the contact area of certain specific gripping state of concrete touch apparatus yet.
In a preferred embodiment of the present application, described method can also comprise:
Receive move operation and the corresponding Mobile data of user on touch apparatus;
According to described Mobile data, determine that corresponding moving contact zone is rectangular linear shape.
In a lot of application programs, usually can use the move operation that slides up and down or horizontally slip, the application can be considered as rectangular linear shape with the corresponding moving contact of move operation zone, and it all is different from parameters such as the shape (ellipse or E type or bar shaped) of the contact area that presets, trends; Especially, because the rectangular linear finger shape of motion track on touch apparatus that is, bar shaped is the shape of this contact area on touch apparatus of finger, thus the difference of the two be, the former is narrower longer, and the latter is wider shorter.Therefore, with respect to prior art, when judging, can at an easy rate this class move operation be rejected away, avoid this class move operation to the interference of result of determination.
In a word, the application is according to the parameter of described contact area, and those skilled in the art can preset based on the physiological property of staff various decision plans, thereby judges that contact area coincide under described contact area and which kind of the gripping state, and it has following advantage:
1, owing to adopting decision plan based on the physiological property of staff, and described decision plan meets objective law and not take subjective will as transfer, therefore can improve the accuracy of result of determination, avoids move operation etc. to the interference of result of determination;
2, determination strategy is automatically, does not need first term, the track or the action that do not need the user to remember, and everything is all carried out on the backstage by machine, need not user intervention, to user's burden not;
3, especially, when judging, can at an easy rate move operation be rejected away, avoid this class move operation to the interference of result of determination, therefore have advantages of that the noise of judgement is little, main support and the identification that relies on the hardware, very low to user's performance accuracy requirement itself;
