The touch-control processing unit of the embodiment of the present invention is described more fully below.As shown in figure 5, being to implement according to the present invention
The function of the touch-control processing unit of example realizes schematic diagram.In order to more clearly describe the function of each module in the touch-control processing unit
Can, the ROD4 equipment and application program that data communication is carried out with the touch-control processing unit are also shown in Fig. 5.
As shown in figure 5, touch-control processing unit of the invention specifically includes that parameter configuration module, data disaply moudle, data
Parsing module, object detection module, data transmission blocks, wherein parameter configuration module includes parameter access module and parameter tune
Mould preparation block.
Parameter configuration module is used in the starting of touch-control processing unit, Configuration network parameter and sweep parameter.Configuration network
Parameter, i.e. setting network address and port, network parameter specifically include:
The IP address (IP1) of touch-control processing unit；
Touch-control processing unit receives the network port (D1) of data from ROD4 equipment；
Touch-control processing unit sends the network port (D2) of data to application program；
The IP address (IP2) and port (D3) of ROD4 equipment；
The IP address (IP3) of application program and port (D4) etc..
Wherein, touch-control processing unit and application program are realized on the same computing device, and therefore, IP address IP1, IP3 can
With identical, the network port number D1 and D2 of touch-control processing unit are generally different.
The scanning range and scan frequency of ROD4 equipment is mainly arranged when configuring sweep parameter in parameter configuration module,
Wherein, scanning range is determined by parameters such as position, angle, rotation, the scalings of setting ROD4 equipment.Scan frequency is settable
It, can also be with other numerical value of self-setting for the default scan frequency of ROD4 equipment.For user click or double-clicking touch screen,
The time that user executes double click operation is usually 0.3 second, therefore the scan frequency value of self-setting cannot be too small, need to guarantee to scan
The clicking operation twice of user can be captured in interval simultaneously.
Data resolution module, for receiving ROD data that ROD4 equipment sends (refer to ROD4 equipment send data),
And parse the ROD data, needs according to an embodiment of the present invention, it is only necessary to the contact information of user terminal in ROD data is parsed,
Resolving are as follows: the location information of the user contact is obtained from the contact information, which is polar coordinates information.It should
Resolving can for example be carried out by Software Development Tools SDK packet that ROD4 device manufacturer provides.
Object detection module, for obtaining the location information for the user contact that parsing obtains from data resolution module, according to
The area of the positional information calculation of the user contact user contact, and the area of the user contact is compared with preset threshold
Compared with if the area less than preset threshold, determines that the user contact is a touch point, otherwise, it is determined that the user contact is
One touch surface.
Wherein, when determining the user contact is a touch point, the polar value of the touch point is converted into corresponding to
The rectangular co-ordinate value of application server end screen.When determining the user contact is a touch surface, need the touch first
Face is converted into a circle, and takes the circular center of circle as touch point, then again converts the polar value of the touch point
At the rectangular co-ordinate value for corresponding to application server end screen.
After object detection module obtains rectangular co-ordinate value, a figure can be drawn according to the rectangular co-ordinate value as mould
Quasi- contact, to indicate position of the rectangular co-ordinate on the screen of application server end, wherein the figure can be circle,
It can illustrate the figure of analog contacts position for other.
Data disaply moudle, for show ROD4 device hardware information, the sweep parameter of ROD4 equipment, system network match
Confidence breath etc., in addition, being also used to show location information and figure of analog contacts etc..
Data transmission blocks, for analog contacts information to be sent to application program according to predetermined format, to apply journey
Analog contacts information executes corresponding operation to sequence based on the received.Wherein, predetermined format can be data as defined in TUIO agreement
Format, and transmission analog contacts information can be sent by wifi network.After application program receives the analog contacts information, root
Simulated touch event is generated according to the analog contacts information, and by calling application server operating system to touch to execute the simulation
Touch event.
The specific implementation process of the embodiment of the present invention is described below.With the application server operation where touch-control processing unit
System is illustrated using for Windows8 operating system.
Firstly, needing to carry out system configuration in system initialization, carried out by parameter configuration module.Touch-control processing
After device starting, the parameter adjustment module of parameter configuration module starts setting up network parameter, in order to facilitate user setting, the net
Network parameter is shown on data disaply moudle.Parameter adjustment module can recognize the operation of pre-set keyboard and mouse, when monitoring
When operating the keyboard and mouse operation of user, the input operation of response operation user, to complete the setting of network parameter, thus touch-control
Network connection is established between processing unit and ROD4 equipment, application program, and can receive that ROD4 equipment sends initial sweeps
Retouch parameter.
Data disaply moudle shows the initial sweep parameter that ROD4 equipment is sent, and consistency operation user is adjusted by parameter
Module respond user keyboard and mouse operation, these sweep parameters are adjusted, for example, can by way of mouse drag tune
The size of whole scanning area, and can be using keyboard shortcut come handoff functionality, such as pass through the progress parameter resetting of ALT+R shortcut key
Operation.
Configure complete network parameter and sweep parameter be recorded in configuration file, and by parameter access module come
Store these configuration files, wherein configuration file can be xml document.It is subsequent usually in the case where not changing system hardware
In use process, only stored configuration file need to be read from parameter access module and is shown in after the starting of touch-control processing unit
On data disaply moudle, Parameter Configuration process can be completed.
When there is user to touch user terminal screen, ROD4 equipment is to collect the contact data of the user, and data parse mould
Block parses the location information of user contact from the data of contact, and sends object detection module, object for the location information
Polar value in the location information is converted into the rectangular co-ordinate value of application server end screen by detection module, and straight according to this
Angular coordinate value draws an analog contacts.Data disaply moudle shows the analog contacts corresponding in application server end screen
On position.Meanwhile the location information of the analog contacts is sent data transmission blocks by object detection module.Data transmission blocks
The location information of the analog contacts is converted into the location information of TUIO format, and is sent to application program.Application program receives
The location information of the TUIO format simultaneously generates simulated touch event, executes the simulation by calling application server operating system
Touch event, so that analog subscriber touches behavior.
Technical solution according to an embodiment of the present invention receives the contact information for the user terminal that Laser Scanning Equipment is sent, and
