Concrete criterion of identification can be analogized according to foregoing description, repeats no more here.
When carrying out character when input, the movement locus of these types can correspond to the first information that is used to carry out control operation (such as confirming, move, return etc.) as required.
In the present embodiment, the said first information can comprise stroke, character (for example, English and numeral) or steering order; In the type and the corresponding relation between the first information of the said movement locus that prestores, all types of movement locus can correspond respectively to one or more said first information; Can be under the different conditions corresponding to the different first information, also can be all to classify several kinds of first information of correspondence as candidate item.
In practical application, all types of movement locus can correspond respectively to one or more stroke, the movement locus of some type can also be only corresponding to or except stroke also corresponding to the first information as steering order.Be specially, when operating body carried out move operation on this sensing device, sensing device was responded to the corresponding movement locus of said move operation, the type of identification movement locus; The type control instruction corresponding of confirming said movement locus according to the type and the corresponding relation between the steering order of the movement locus that prestores.For example, the type identification of said movement locus is the corresponding steering order that moves of bias type track; The type identification of said movement locus is an arc line type track corresponding rotation steering order.
Further, obtain one or more object of current demonstration, according to above-mentioned this one or more object of steering order control.
In addition, except movement locus, can also operate through other of inductive operation body and control, confirm such as " click " or " double-click " expression, " long by " expression gets into previous menu etc.
When using OFN record movement locus; Can also come pushing of inductive operation body through OFN; Thereby confirm operational orders such as " click ", " double-click ", " long pressing ", these operational orders can correspond respectively to the Different control instruction, such as " confirming ", " returning " etc.; Certainly, do not get rid of to operate yet and represent steering order with other.
Such as said straight horizontal line style track from left to right; Except "-" in, the English/numeral horizontal corresponding to stroke, can also be corresponding to the steering order of " moving right ", when in input state following time; With said straight horizontal line style track identification from left to right is stroke; And provide the corresponding candidate frame of corresponding stroke, such as " 1, T 2, Z 3,74,1, no " if this moment operating body carried out the operation that " double-click " or " click " etc. " confirmed " corresponding to steering order, then get into selection mode; Be " move right " with said straight horizontal line style track identification from left to right this moment, and then cursor (Gao Liang) will move right in candidate frame.Carried out operations such as " double-clicks " or " click " once more when operating body after, select the option of current cursor position, return input state then; Or operating body carried out corresponding to steering order " return " or the operation of " cancellation " after return input state.
Embodiment two; A kind of data inputting method, said method are applied in the data processing equipment, and said data processing equipment comprises an inductor; Said inductor can the inductive operation body pressing operation can respond to the move operation of said operating body simultaneously, said data inputting method comprises:
Write down first movement locus that said operating body produces when said inductor carries out move operation,
Identify the type of said first movement locus;
According to the type of the movement locus that prestores and the corresponding relation between the first information, obtain at least one first information that said first movement locus is represented by the type of said first movement locus that identifies;
Accept the operational order that produces when said operating body carries out pressing operation to said inductor, second movement locus that produces when writing down the move operation that operated body carries out on said inductor;
In said at least one first information, confirm second information according to said operational order and said second movement locus.
In the present embodiment, can judge the glide direction of said operating body, thereby the control cursor is mobile according to second movement locus that is write down; Can also further judge the sliding distance of operating body according to the length of second movement locus, perhaps according to the starting velocity of second movement locus, thus the distance that the control cursor moves.
