Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The method for starting the specific function provided by the application can be applied to the hardware environment shown in FIG. 1. A variety of applications may be installed in the interactive smart tablet 100, such as a text editing application, a document presentation application, an instant messaging application, an image editing application, and so on. The system comprises a text editing application program, a document demonstration application program, an instant messaging application program and a video conference application program, wherein the text editing application program comprises an electronic whiteboard application and an electronic blackboard application, the document demonstration application program comprises a wireless screen projection application, and the instant messaging application program comprises a video conference application.
In an embodiment, the screen of the interactive smart tablet 100 may be a capacitive touch screen, and a user may perform a touch operation on the capacitive touch screen through a finger or the capacitive pen 200, and the interactive operation performed by the user on the interactive smart tablet 100 through the capacitive pen 200 includes, but is not limited to, a click operation, a selection operation, or a writing operation.
The capacitive touch screen works by utilizing current induction of a human body; the capacitive pen 200 is an auxiliary device for performing a man-machine conversation by using a conductor material to imitate a human body (usually a finger).
The capacitive pen 200 for interacting with the interactive smart tablet 100 may include a passive capacitive pen that simulates the touch effect of a finger and an active capacitive pen that is made of a conductive material such as conductive foam, metal, and a brush as long as the pen point is enough to affect the capacitance change. In general, passive capacitive pens are very thick nibs and therefore have poor touch accuracy. The nib material of the active capacitance pen adopts a novel POM (polyacetal) material with high strength, high impact resistance and excellent smoothness, a sensor is arranged in the nib material, and can actively detect signals in the capacitance touch screen so as to give out signals.
In one embodiment, as shown in fig. 2, an interactive smart tablet manipulation method is provided, which is applied to the interactive smart tablet 100 of fig. 1. Specifically, the interactive smart tablet control method may include the following steps:
s110, receiving a touch event on an interactive smart tablet screen; the screen is a capacitive touch screen.
In embodiments, the interactive smart tablet screen touch event may be any touch event commonly implemented based on a capacitive pen, including but not limited to a click event, a selection event, or a writing event.
And S120, determining that the touch event is a target event, wherein the target event is an event that a target part of the capacitive pen contacts the screen.
In an embodiment, the target portion of the capacitive pen is a portion other than the pen tip, that is, the target portion is a portion other than the pen tip. It is thereby possible to distinguish whether the user's current operation is a normal touch operation or a touch operation for starting a specific function.
S130, sending a starting signal to the flat main system; the starting signal is used for triggering the panel main system to start a specific function in the interactive intelligent panel.
In an embodiment, the specific function in the interactive smart tablet is related to a state of the interactive smart tablet when the target event occurs, for example, if the interactive smart tablet is in a whiteboard state when the target event occurs, the specific function may be an eraser function; if the interactive smart tablet is in a screen projection state when the target event occurs, the specific function may be an annotation function.
In an embodiment, the main body for executing the steps in fig. 2 may be a touch controller, the touch controller is configured to detect and recognize touch data on a screen, and the touch controller is capable of communicating with a tablet host system of an interactive smart tablet to send the acquired touch data to the tablet host system. Based on this, after the touch controller detects the touch event, if the touch event is identified as an event that the target part of the capacitive pen contacts the screen, a start signal is immediately sent to the tablet main system to notify the trigger tablet main system to start a specific function in the interactive smart tablet.
Through the interactive intelligent tablet control method of the embodiment, when the specific function in the interactive intelligent tablet needs to be started, a user does not need to operate a related menu or a specific option, and only needs to make the target part of the capacitive pen close to the screen, so that the specific function in the interactive intelligent tablet can be quickly started.
In an embodiment, in order to facilitate a user to touch the screen with the capacitive pen, the target portion of the capacitive pen in the above embodiment is selected as the pen tail of the capacitive pen. When the specific function in the interactive intelligent tablet needs to be started, a user does not need to operate a related menu or a specific option, and only needs to make the pen tail of the capacitive pen close to the screen, so that the specific function in the interactive intelligent tablet can be quickly started, and other conventional functions of the capacitive pen are not influenced.
In one embodiment, an existing capacitive pen is modified for the purpose of enabling rapid activation of specific functions in an interactive smart tablet. Referring to fig. 3, not only the pen tip but also a target portion, which does not include the pen tip, is provided on the capacitive pen body; and filling the target site with a conductive material. That is, when the target portion of the capacitive pen contacts the capacitive touch screen, the touch screen controller can detect the touch event.
Further, with continued reference to fig. 3, in some embodiments, the target portion is selected as a tail of the capacitive pen, thereby not affecting the normal operation of the capacitive pen, but increasing the touch function of the capacitive pen.
With continued reference to FIG. 3, in some embodiments, the target locations are selected as multiple regions on the trailing face of the pen, and the multiple regions are separated from each other. For example: the target site is 4 areas on the face of the tail end of the pen, and the 4 areas are separated from each other, as shown in fig. 3.
In addition, in order to further distinguish the touch event of the target portion from the ordinary multi-touch event, in some embodiments, the 4 regions further need to satisfy certain conditions, for example: the central points of the 4 areas are taken as vertexes, and the formed closed graph is rectangular; alternatively, the center points of the 4 regions are set as vertexes, and the formed closed figure is a square.
In addition, according to the specific shape of the capacitance pen body, the multiple areas of the pen tail can be set to other forms or meet other conditions.
Based on the improved capacitive pen in various forms, in some embodiments, the specific implementation manner of step S120 may include: acquiring touch point data contained in the touch data; and if the touch point data meets the set conditions, determining that the touch event is a target event. For example: and if the touch point data comprises data of 4 touch points and the data of the 4 touch points meet set conditions, determining that the touch event is a target event.
Further, in order to reduce the occurrence probability of the malfunction, the setting condition may include: a closed graph formed by taking the 4 touch points as vertexes is a rectangle; or, the closed graph formed by taking the 4 touch points as the vertexes is a square. In some other embodiments, the setting condition may also include: the distance between two adjacent touch points in the 4 touch points is equal to a preset distance value, for example, the distance between two points AB, two points AD, two points BC, and two points CD in fig. 3 is fixed.
In addition, the setting conditions may be adaptively adjusted for other types of target site selection.
Further, in some embodiments, in a specific function starting state in the interactive smart tablet, if the target event is detected again, an exit signal is sent to the tablet host system; the exit signal is used for triggering the flat panel main system to exit the specific function.
For example, when the interactive intelligent tablet is in a whiteboard state and the eraser function is started, the user contacts the capacitive touch screen with the target part of the capacitive pen again, so that the user can quickly exit the eraser function, and further, the user can conveniently perform other whiteboard operations.
It should be understood that for the foregoing method embodiments, although the steps in the flowcharts are shown in order indicated by the arrows, the steps are not necessarily performed in order indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise.
