Herein, what is called is the wrong identification character at a slow speed, refers to that handwriting character input device 100 will be actually moment that handwriting input character midway interrupts from handwriting input through laggard line character identifying processing of the schedule time and definite character automatically.The user in handwriting input midway, if for example point from touch panel 101, leave during through the schedule time, even handwriting input character midway, handwriting character input device 100 also will carry out the character recognition processing and automatically determine by this character.

Upper at the picture (1-1) of touch panel 101, as the user with finger touches wrong identification character “ Door at a slow speed ", the user can move it (for example drag operation) using wrong identification character at a slow speed on the S1 of viewing area as object.

Picture (1-2) at touch panel 101 is upper, and the user drags wrong identification character “ Door at a slow speed by finger from viewing area S1 ", be placed in input area S2.Then, upper at the picture (1-3) of touch panel 101, be placed to the character of the wrong identification at a slow speed “ Door in input area S2 " be shown in input area S2.Now, input area S2 is with can be from through the person's handwriting (Ji “ Door in the moment of wrong identification at a slow speed ") proceed the state of handwriting input, show wrong identification character “ Door at a slow speed ".Therefore, upper at the picture (1-4) of touch panel 101, the user can continue to input person's handwriting from wrong identification person's handwriting (i.e. " Door ") constantly at a slow speed.

When the user will be at a slow speed the wrong identification character from viewing area S1 drag and be placed into can handwriting input input area S2 the time, the related handwriting character input device 100 of embodiment 1 can become can be by wrong identification character at a slow speed handwriting data during from wrong identification at a slow speed proceed the state of handwriting input.

With reference to Fig. 2, to embodiment 1, the structure of related handwriting character input device 100 describes.Fig. 2 means the calcspar of the structure of handwriting character input device 100.Handwriting character input device 100 shown in Fig. 2 possesses touch panel 101, the second display part 103, display control unit 105, placement function controlling part 107, the second impact damper 109, stroke data acquisition unit 111, handwriting data acquisition unit 113, identification engine 115, stroke information retaining section 116, CPU117, the first display part 121, drag function control part 123 and the first impact damper 125.

Touch panel 101 is in the situation that, as input interface performance function, the contact of detection finger etc., export this testing result to handwriting data acquisition unit 113 and drag function control part 123.

In addition, touch panel 101 possess integratedly the first display part 121 of Identification display character etc., and as the second display part 103 of hand-written character input area.Therefore, the second display part 103 can carry out and the corresponding demonstration that contacts detected on touch panel with the first display part 121.

Herein, the contact that so-called touch panel 101 detects is for example the contact of user's finger.

The control of the first display part 121 (being equivalent to viewing area S1 in Fig. 1) based on display control unit 105, be presented at the character kept in the first impact damper 125.

In addition, the first display part 121 is wholely set with touch panel 101.Therefore, the user, drag in the situation that the character shown in the first display part 121 of touch panel 101, the first display part 121 can show the movement with the character of this touch panel operational correspondence.In addition, the control based on drag function control part 123 described later, be controlled at the movement of the character shown in the first display part 121.
