In a preferred embodiment of the present application, the parameter of described contact area can be obtained by following steps:
Steps A 1, obtain the peripheral coordinate points of described contact area;
Such as, for the determined contact area of step 202, first can carry out discretize to it, be decomposed into the point of various discrete, then, find in contact area and be positioned at outermost discrete point, be also peripheral coordinate points.
Steps A 2, by connect all or part of described peripheral coordinate points, produce the profile of described contact area;
Steps A 3, profile according to described contact area, determine the shape of described contact area;
For the touch apparatus of one side touch screen, usually only there is place's contact (thumb contact), therefore all or part of described peripheral coordinate points can be connected to form the profile of a contact area by straight line.For application scenarios 1, left hand thumb forms the profile of a contact area on the touch screen of mobile phone front, and can determine that the shape of this contact area is sub-elliptical type.
In particular cases, two contact areas that the contact of two places is formed are had.For application scenarios 2, left hand forms the profile of the contact area of a sub-elliptical type in the left side of panel computer touch screen, and meanwhile, right finger also forms the profile of the contact area of a sub-elliptical type on right side.
And for two-sided and/or two-sided and side touch screen touch apparatus and there is the touch apparatus of back side touch screen, often there is many places contact, therefore all or part of described peripheral coordinate points can be connected to form the profile of multiple contact area by straight line, and the shape of each contact area can be obtained further, as E type, bar shaped or rectangle etc.
Certainly, except straight line connects, all or part of described peripheral coordinate points can also be connected to form the profile of contact area by curve, do not limited at this,
Steps A 4, according to the profile of described contact area relative to the direction of reference point, obtain the trend of described contact area;
In specific implementation, can set up the frame of reference, horizontal ordinate is x, and 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 application scenarios 1 time mobile phone, it is true origin (0 with the upper left corner on mobile phone, 0), y-axis is down, elliptic region in figure represents the contact area that left hand thumb is formed on the touch screen of mobile phone front, then can represent the trend of this elliptic region with the angle α of the major axis of this elliptic region or minor axis and x-axis.
Certainly, just exemplarily, those skilled in the art can adopt any means obtain and describe described trend, and the application is not limited this for the method for the trend of the described contact area of above-mentioned acquisition and the description of trend.
Steps A 5, according to the central point of the profile of described contact area relative to the position of reference point, obtain the distribution of described contact area.
If there is multiple contact area, this step then needs to obtain the position of central point relative to true origin (0,0) respectively.
When the canonical parameter of the contact area by the parameter of described contact area and certain specific grip state compares, if adopt multiple parameter, can compare separately.Suppose have employed shape and move towards two parameters, then, when the corresponding comparative result of shape and trend is all in preset range, can judge that the grip state of user is as this specific grip state.
At vpg connection, the registration (or misalignment) of two shapes can be compared.For the contact shape of thumb, in practice, if gather the contact data of user under various grip state, thus the canonical parameter of the contact area of preset specific grip state; What then compare is the registration of identical thumb, now, can arrange larger by registration threshold value, as 95%.And if canonical parameter is according to the contact data initialization of non-user under various grip state, the shape due to different thumb has difference, therefore can arrange less registration threshold value, as 80% etc.Normally, if the registration of the two is greater than registration threshold value, then think that comparative result is in preset range, the misalignment of the two is less than misalignment threshold value, then think that comparative result is in preset range, the application is not limited the concrete setting of registration or misalignment and concrete numerical value.
In moving towards, can according to the sample data gathered, the standard angle scope of the contact area of preset specific grip state, if by the trend of described contact area within the scope of this standard angle, then thinks that comparative result is in preset range.
For application scenarios 1, the touch shape that identical left hand thumb is formed on the touchscreen is identical, but each grip position difference determines trend and distribution changes simultaneously.Therefore actual specific comparatively time, can also using trend and distribution as a pair parameter, jointly compare.
For application scenarios 1, the parameter supposing the contact area that left hand thumb is formed on the touch screen of mobile phone front all leftward in the standard trend of the contact area of grip state and the preset range of shape, then can judge that user is in left-handed state.For application scenarios 2, although right-hand man forms a contact area respectively on panel computer, but, in the preset range of the parameter of the contact area formed in the left side of panel computer touch screen due to the left hand canonical parameter of the contact area of grip state leftward, therefore also can judge that this user is in left-handed state.
Above the comparison procedure of shape, trend and distribution three parameters is illustrated, be appreciated that the comparative approach of the application is not limited to above-mentioned example.Further, the parameter of the application is also not limited to above-mentioned three parameters, and the application is not limited concrete parameter and concrete comparison procedure.
The application is according to the parameter of described contact area, and the physiological property based on staff judges which kind of grip state described contact area belongs to.The application provide only the canonical parameter of the contact area of certain specific grip state of three kinds of touch apparatus, in fact, those skilled in the art can also according to the use habit of the physiological property of staff, the size shape of touch apparatus and handling characteristics, user, the canonical parameter of the contact area of certain specific grip state of other touch apparatus preset, the canonical parameter of the application to the contact area of certain specific grip state of concrete touch apparatus is not also limited.
In a preferred embodiment of the present application, described method can also comprise:
Receive user's moving on touch apparatus to operate and corresponding Mobile data;
