if a plurality of characters are input and the average input time interval is greater than 50ms, determining that the characters are manually input;
if a plurality of characters are input and the maximum input time interval is greater than 100ms, determining that the characters are manually input;
if the number of the input characters is greater than 10, counting the standard deviation of the input time interval, and if the standard deviation value is greater than 15, considering the input time interval as manual input;
if the determination condition of the manual input is not satisfied, the machine input is automatically determined.
3. The intelligent text box input method according to claim 1, wherein data which does not fall within a preset range is directly abandoned and an error prompt is sent out.
4. The intelligent text box entry method of claim 1, wherein after listening to and capturing the operating system wm_char message, further comprising identifying the content of the wm_char message:
if the content is a valid character, recording the time of each WM_CHAR message generation and the time interval of adjacent character generation;
if the content is invalid character, the captured message is ignored.
5. The intelligent text box entry method of claim 4, wherein the valid characters include digits 0-9 and uppercase letters a-Z, lowercase letters a-Z.
6. An intelligent text box input device, comprising:
a setting module for setting a text input object, wherein the text input object is only allowed to be manually input, only allowed to be machine input or allowed to be manually input and machine input simultaneously;
the acquisition module is used for monitoring and capturing WM_CHAR information of the operating system, recording the time of each WM_CHAR information generation and the time interval of adjacent character generation, and storing the time intervals in a time array;
the processing module is used for calculating the data in the time array to obtain an average time interval t avg Maximum interval time t max Standard deviation t of time interval dev Judging whether the input data falls into a preset range, wherein the preset range is different according to different text input objects which are initially set, and the preset range is obtained by collecting time parameter information of manual input data and machine input data and statistically analyzing an average time interval range R of manual input avgh Maximum interval time range R maxh Standard deviation range R of time interval devh Average time interval range R of machine input avgm Maximum interval time range R maxm Standard deviation range R of time interval devm ；
The method for judging whether the preset range is met is as follows:
if the set text input object is that only manual input is allowed, t avg ∈R avgh ，t max ∈R maxh ，t dev ∈R devh Judging that the preset range is fallen into, otherwise, not falling into;
if the set text input object is only allowed to be input by the machine, t avg ∈R avgm ，t max ∈R maxm ，t dev ∈R devm Judging that the preset range is fallen into, otherwise, not falling into;
if the set text input object is the text input object allowing manual input and machine input, t avg ∈R avgh ，t max ∈R maxh ，t dev ∈R devh Or t avg ∈R avgm ，t max ∈R maxm ，t dev ∈R devm Judging that the preset range is fallen into, otherwise, not falling into;
and the execution display module is used for displaying the content in the text input box when the content falls into a preset range.
7. The smart text box input device of claim 6, wherein the device further comprises:
the identification module is used for identifying the content of the captured WM_CHAR message, and if the content is a valid character, recording the time of generating each WM_CHAR message and the time interval of generating adjacent characters; if the content is invalid character, the captured message is ignored.
