Embodiment
In order to improve the set-up mode of guide line; Further improve user's writing experience; The invention provides a kind of new hand-written inputting method; The generation position that can make guide line changes with the variation of writing pencil input end position, avoids in prior art, bringing the guide line user's constraint sense, improves user's experience.Combine accompanying drawing that the present invention is done further explain through embodiment below.
Hand-written inputting method in this example may further comprise the steps, and sees also Fig. 1:
Viewing area on the display screen is divided into a plurality of demonstration subregions;
In the coverage of distance display screen, detect the current location of writing pencil input end, obtain writing pencil input end current corresponding position information in the viewing area according to its current location;
Confirm writing pencil input end current pairing first demonstration subregion in said viewing area according to said positional information;
In the current pairing first demonstration subregion of said writing pencil input end, generate guide line.
When the writing pencil input end in this example is meant the user with the writing pencil input characters; An end that directly contacts with display screen; Certainly, in order to satisfy user's individual demand, some manufacturer the two ends of writing pencil be set to can with display screen effect handwriting input end.Can be used for hand-written that and look closely and be the writing pencil input end this moment with the user is current.
The viewing area of being presented in this example on the display screen comprises a plurality of demonstration subregions; Each shows that subregion is used to show at least one literal; But the literal of its demonstration can not surpass the number of its regulation; As reach the number of its regulation, it is saturated to think that then this demonstration subregion has shown, does not allow display text in this demonstration subregion again.The coverage of this routine middle distance display screen is meant that system can detect the coverage of writing pencil input end; Promptly as long as the distance of writing pencil input end distance display screen during smaller or equal to above-mentioned coverage; System just can detect the position of writing pencil input end; And then obtain it and be mapped to the positional information on the viewing area, obtain the writing pencil input end in the viewing area current correspondence first show subregion.The positional information of writing pencil input end can be represented with the point on the two-dimensional coordinate in this example, only needs then to judge that point on this two-dimensional coordinate falls into the viewing area which shows that subregion gets final product.
After having confirmed that writing pencil input end current pairing first shows subregion, can in this shows subregion, generate guide line in this example, soon in this demonstration subregion, write or display text to remind the user.
Certainly, according to actual needs, after definite writing pencil input end current pairing first shows subregion, also can in the demonstration subregion adjacent, generate guide line simultaneously in this example, for the user provides a bigger reference zone of writing with this demonstration subregion.Concrete, can be on preset direction in this example, show N the demonstration subregion inner control generation guide line that subregion is adjacent successively with writing pencil input end current corresponding first.Preset direction in this example also can specifically be provided with according to the user personality demand; For example; Can be set to show that with above-mentioned first subregion is a starting point, extend from left to right, or extend from the bottom up or extend from top to bottom etc.; Consider presentation direction that the user is accustomed to for from left to right, the preset direction in this example is for from left to right.Preset value N in this example can be a preset fixed value, also can be the on-fixed value.Preset N be fixed value situation for example: N is made as 2, then is illustrated on the preset direction, also with first show that adjacent 2 of subregion show in the subregions and show guide line; Preset N is that the situation of on-fixed value comprises: show that with first subregion is a starting point; Guide line extends along said preset direction; Whether the demonstration subregion that system detects the guide line process has automatically shown saturated; Show that to run into first saturated demonstration subregion is a terminal point, the N value just is the number of (can comprise or not comprise that said beginning or end place shows subregion) of the demonstration subregion between starting point and the terminal point.
It should be noted that; In this example; Move to the second place when detecting the writing pencil input end by primary importance; Being the corresponding demonstration subregion of writing pencil input end shows that by first subregion changes to second when showing subregion, shows in the subregion second also to generate guide line, promptly in the current demonstration subregion that the corresponding demonstration subregion of writing pencil input end changes to, generates to show guide line.Therefore the guide line in this example can change according to the variation of writing pencil input end position or extend automatically, can guide the user to import immediately, again can limited subscriber write the zone, bring the user and better experience.
Further; Consider that the user is when a certain demonstration subregion writing words; May fall into other demonstration subregion owing to writing style causes the part of wherein some or several writing strokes; And this moment, the user really want to show writing words in the subregion at above-mentioned other, and this moment, the user did not hope in these show subregion, to show guide line.To this situation; Also can preset buffer distance as required in this example solves; Be the writing pencil input end move to the second place by primary importance; Being the corresponding demonstration subregion of writing pencil input end shows that by first subregion changes to second when showing subregion, judges the distance of its variation, or whether the distance that the location map of judging current writing pencil input end shows the subregion border to the positional information (point on the two-dimensional coordinate) and first on the viewing area is greater than preset buffer distance; If then judge the current second demonstration subregion that fallen in writing pencil input end position; If not, thinking then that writing pencil input end position is current still is in first and shows subregion.
Further; When the demonstration subregion that is judged to be writing pencil input end correspondence shows that by first subregion changes to the second demonstration subregion; Second show the guide line that generates in the subregion color or/and line style or/and display mode can show that subregion is different with first; Be convenient to distinguish like this, write scope, be convenient to the user and in time adjust according to the actual wish of oneself with what better prompting user had exceeded former demonstration subregion.Preferably, show that second the color that guide line that subregion generates can be set to show with former demonstration subregion is different, specifically can be: show that first subregion when green, shows that second subregion then can be shown in red or yellow; The line style difference specifically can be: show that first subregion is a straight line, show that second subregion is shown as the less wave of curvature; The display mode difference can be: show that first subregion shows with the mode of static state, and show that second subregion shows with the form of animation, for example show with the form of flashing.
Optional; First shows that the guide line and second that subregion shows shows that the guide line that subregion shows can be same guide line; Promptly show that from first subregion moves to second when showing subregion when the position of writing pencil input end, this guide line is also along with moving (but moving respective change such as its color of back, line style); It can certainly be different guide lines.Preferred as this example, show that first the guide line and second that subregion shows shows that the guide line that subregion generates is different guide lines.
When in the second demonstration subregion, generating guide line; Comprise that also deletion first shows the guide line that generates in the subregion; Because fallen into above-mentioned second and show subregion through the positional information of the current writing pencil input end of above-mentioned judgement is current, this shows that very likely the user has transferred to second and shown in the subregion and write that therefore former first shows that the guide line that shows in the subregion is nonsensical basically; Therefore take processing mode in this example, make the interface that demonstrates more succinct its deletion.
As preferably, in showing the demonstration subregion of guide line, the time that does not detect the current location of writing pencil input end is deleted the interior guide line of this demonstrations subregion when surpassing preset time T.Because show subregion at some, the user directly starts writing and has not write after possibly writing and finishing, if do not do above-mentioned processing, these show that subregion will show guide line always, and the demonstration of these guide lines does not have practical significance.
In this example, before first or second of the current correspondence of writing pencil input end shows to show guide line in the subregion, also can comprise and judge that said first shows whether subregion has shown saturated; As saturated, then do not show in the subregion to generate guide line second.Because show that saturated demonstration subregion does not allow display text within it again, so in this sub regions, no longer show guide line in this example.Preferably, this example can allow the user to write at the saturated demonstration subregion of these demonstrations, but the standard word after the former person's handwriting identification of writing can not show that saturated demonstration subregion shows at these.
Certainly; Also can be chosen in this example and show that saturated demonstration subregion generates guide line; The guide line that the guide line that just in this type shows subregion, generates needs to generate with other subregions distinguishes, and for example can show its overstriking, or send the prompt tone etc. of alarm when showing.
Show when saturated running into above-mentioned demonstration subregion, also can show that the adjacent next unsaturation of subregion shows that subregion generates guide line with this.So not only can remind the user that the current demonstration subregion of writing shows saturated; Also can further remind which subregion of user can show the literal that it is write; The clearer and more definite literal of oneself writing of user will be shown in which zone; Or target is clearer and more definite when adjusting accordingly, and improves the satisfaction of user experience.
In this example; When the displacement on display screen of writing pencil input end hour, also may appear at the situation that demonstration subregion that the writing pencil input end fallen into has shown guide line, to this situation; In this example before the current demonstration subregion that falls into of the positional information of writing pencil input end shows guide line; Judge also whether this demonstration subregion has generated guide line, in this way, then in this demonstration subregion, does not repeat to generate guide line.Certainly also can be chosen in the generation guide line of this demonstrations subregion repetition if necessary, the guide line that repeats the to generate demonstration that is superimposed, just the same with the effect that does not repeat to show.
Also can select according to actual conditions in each length that shows the guide line that subregion generates in this example, the length of this routine desirable guide line is long for M preset character.The size of M in this example also can decide according to each size that shows subregion, and for example, when the length of selecting to make guide line and each showed that the length of subregion is identical, the size of M had just depended on the size that shows subregion fully.Preferably; The guide line setting that respectively shows demonstration in the subregion in this example can be set to overlap with each one or more boundary line that shows subregion; Even can be overlapping fully with all boundary lines of a certain demonstration subregion; Promptly when a certain demonstration subregion generated guide line, each zone that surrounds of guide line just was this demonstration subregion, can give the clearer and more definite guidance of user.
Can know that to sum up the guide line in this example can be followed the variation of writing pencil input end and shown dynamically, does not need to show at all demonstration subregions simultaneously, also need not be fixed in a certain demonstration subregion demonstration.It in which zone shows and the length of demonstration time all can be decided according to the situation of change of writing pencil input end, can bring user's better writing experience.Simultaneously, color, line style and the display mode that the guide line in this example shows also can be different and different according to the type that shows subregion, can better point out, guide the user.
See also Fig. 2, this example also provides a kind of hand input device, comprises display screen, the detection module that is connected with display screen, and the guide line generation module that is connected with display screen with detection module, in this example:
The viewing area that demonstrates on the display screen comprises a plurality of demonstration subregions, is used to control display text and guide line;
