First, receive by study module 26 multiple touch points (step S302) that touch-screen detects, foreground program in being used at present by monitoring modular 24 detection. electronics thus, and Query Database 22 can be for the original scope (step S304) of touching to obtain in the operation interface of this foreground program at least one touching target and each touching target.Wherein, the touching target and each touching target that in described database 22, have recorded in the operation interface of multiple foreground programs can be for the original scopes of touching, and monitoring modular 24 for example can be in one section of set time detection. electronics be used at present foreground program, or in the time that study module 26 receives touch points at every turn the foreground program of detection. electronics in using at present, and the relevant information of touching target in detected foreground program and operation interface thereof is offered to study module 26, therefore by study module 26, these touch points are carried out to analyzing and processing.
In detail, the touching target that study module 26 for example can provide according to monitoring modular 24 and can be for the original scope of touching, judges in its touch points receiving continuously whether the position of multiple touch points of touching is dropped in the original scope of one of above-mentioned touching target (step S306).Wherein, study module 26 for example can judge whether the time interval between received touch points be less than a preset value, and time interval between described touch points while being less than preset value is just regarded as these touch points the touch points of continuous touching.This touch points of touching continuously can be considered it is the continuous touching behavior of user for same target, and can be in order to the foundation of the scope touched as this target of extension.
Finally, in the time that study module 26 judges that one or more position in described touch points is dropped in original scope of one of them touching target, can be according to the position of other touch points in described touch points, determine the follow-up expanded range (step S308) for touching of this touching target.Wherein, study module 26 for example can, for other touch points that drop on outside the original scope of touching target, be found out a minimum rectangular area that can contain these touch points, and in order to touch the follow-up expanded range for touching of target as this.On the other hand, in the time that study module 26 judges that the position of described touch points is not dropped in the original scope of any one touching target, the touch points of this detection can be considered as to invalid touch points, and get back to step S302, again the detected next group touch points of touching screen is analyzed.
It should be noted that, owing to may comprising close or adjacent each other multiple touching targets in operation interface, for avoiding because of the overlapping situation of touching close the caused expanded range of target, in another embodiment of the present invention, can be further according to the configuration of each touching target in operation interface, in database 22, recording each touching target can be for the maximum magnitude of touching.Wherein, described maximum magnitude can be more than or equal to the original scope of each touching target and contain original scope, and can distinguish to some extent with other maximum magnitudes of touching target (meaning is not overlap one another).Therefore, each touching target can be for outside the original scope of touching in query manipulation interface for monitoring modular 24, and also can inquire about each touching target can be for the maximum magnitude of touching.Study module 26 is in the time analyzing touch points, can first filter out position and drop on the touch points outside maximum magnitude, and only according to the position of remaining touch points after filtering, decide the follow-up expanded range for touching of touching target, therefore can avoid the overlapping situation of above-mentioned expanded range.
In addition, due to everyone operating habit difference, the position of the touch points that its reality produces in the time of the same target of touching is also different, and for the touching target on the operation interface of distinct program, the position of the touch points that its touching produces is also not quite similar.To this, in another embodiment of the present invention, can set up exclusive database for different users, so that when storing it and operating different foreground program, in the operation interface of each foreground program, each touching target can be for the expanded range of touching.In detail, in the present embodiment, study module 26 after determining that touching target can be for the expanded range of touching, for example, can first be obtained the user's who logins at present electronic installation log-on message, and whether judges in electronic installation the existing database of setting up this user.If do not set up this user's database, study module 26 can, according to obtained user's log-on message, be set up the exclusive database of this user, and can be for the expanded range of touching in order to storage touching target.
By above-mentioned detection method of touch, electronic installation can be learnt different users's operating habit, for each touching target on operation interface, find out a scope touched that is best suited for this user, and in order to make to touch as subsequent detection user the foundation of operation.And according to the scope touched of these touching targets, electronic installation is in the time of the follow-up touching operation that receives user, can suitably adjust touching target can be for the scope of touching, allows user's operation interface of operating electronic devices more easily.Describe in detail for an embodiment again with next.
