Description of the invention: ―, [Technical field to which the invention belongs] The present invention relates to a device for determining the right to control computer operation when a plurality of people operate a single computer screen together, and to perform the operation control transfer And method. Second, [previous technology] The booming development of the personal computer and Internet industry has changed many life styles and working modes of human beings. The online video conference is one of the best examples. In the traditional conference mode, members of the meeting must be concentrated in the same space and use equipment in the same space (for example, electronic whiteboard) for discussion. Causes the participation of conference personnel in a long time to waste time and money. The development of video conferencing systems has enabled meeting members to conduct multi-party meetings and discussions through their Internet connections at their own designated locations and their respective spaces. Such technology has matured in recent years. Most of today's online video conferencing systems provide online whiteboard functions, allowing meeting members at different far-ends to use shared devices when discussing together. However, the demand for modern conference styles is no longer met by the white version. All e-newsletters, online operations, instant web page information browsing, software operations, online consulting services, etc., need to instantly allow all members of the remote conference to instantly preview and instantly modify. The function of the online electronic whiteboard is not enough to achieve this demand. The best solution is to share the computer screen (share desktop) ^ #(share cursor control)^^ 0 said that the same computer screen is directly used as a device for discussion by multiple parties. The function of sharing the control of the screen with the control of the cursor has been used in the field of remote control in the past, in order to break through the limitations of the computer hardware and software maintenance staff must be in front of the computer host. This kind of care is a 4 - application. In the observation meeting, (10) sharing the picture and sharing the cursor (4) rights is a multi-faceted application, that is, a multi-person system to conduct the discussion. Such an application is not a problem in the computer screen and 1268071. The main problem lies in how many people can easily, intuitively and fairly share the control of the computer's cursor (computer operation control), not causing multiple people to rush to use and control the chaotic situation. ϋ The most well-known method of control of the computer operating system of the drought is the method used by Micr〇s〇ft. The main concept of this method is that when multiple competitors compete for the cursor control, they will first obtain the request and obtain control. After that, it is necessary to passively wait until the cursor control right acquirer releases the cursor control right before the competition cursor control officer can be re-timed. In the case of f-knowledge, it is necessary to find the control system in the program. Once the cursor control is difficult, the rest of the travel control "control button" will immediately expire. Until the user who has obtained the control of the cursor presses "release the cursor to control her", the other person's "obtaining the cursor control age" will take effect again. This kind of custom shared cursor control _, with __, even if _ must _, can correctly obtain and release the cursor control, which is neither convenient nor fair. Third, [invention content], the invention of the Mizaki-Lion View Township _, recording time, operation control = (T is called electric control rights) transfer mechanism to achieve a relaxed, intuitive and fair total =:: invention For many people _ single - the main screen of the computer screen _ brain operation control 〇 < κ < Ν 〜 ~ fine - purchase rights. Reader's computer (Ρκ7--Enabler computer (ρ.), for · shared recording and computer operation control Na Wei Wei to decide what--between, participant computer in 1268071 Next steps: For convenience of explanation, first define the following Representation: S(K)={Pi|〇Si<N} •• A group of users share the picture R ·· represents a group of users who require control. ρκ has the control of the game. <χ,γ> ; : indicates that the control of the cursor is transferred from Ρχ to ργ. β ·· indicates a period of time, when there is control, no electrical interval is performed. Time of brain operation control action ta(K): indicates that the user desires cursor control Time of arrival td(K): indicates the time when the user 间 κ starts. 01 In a group of users S (K), 02 settings; settings; (face money computer p. Get control) 03 check p. Whether it is idle; (set P. has the highest power) 04 If no, county control, unconditional _ v < K G >, (four); set (four)]; OS accepts other participants computer request control, R = RUIM new request user }; 06 Check whether the computer ρκ that has obtained control is idle, and whether the time is super Over-threshold value p; 07 If the 'Lion has requested the control _ participants' R, select the first request for control power fine Pj' and meet ta (J)-td (K) $ P. And set the computer to obtain Controls <K,J>;K=J; Set R=[cp]; 〇8 returns to step 〇3 until the end of the operation. [Embodiment] 1268071 Other objects and advantages of the present invention The present invention is for a plurality of people The single implementation of the joint operation. It can be more clearly explained in the following detailed description. The following describes the computerized master of the computer «Computer operation control right transfer device and method does not invent the active computer for multiple people to operate a single computer screen together Operation control transfer device mapping. Such as coffee, she (10) people fine _ - electric active computer operation control (four) transfer device has ··__« (8), to open the «shared function of the computer; most of the participants computer (Ρκ, 总 is the total illusion of all participating computers... network communication system, used to connect the number of participants to the computer Ρ κ. Each of the participating computers, the # active control of the transfer mechanism, but the mother and child operations 'only provide — The computer-like mechanism shared by the screen will be activated.斑人电脑Ρκ能科科-Computer ^ screen display message, add _ show and - screen 魄 modify the right to move the view 'Chan Nen-Calang turn (10) tender paste (four) Na change the contents of the single computer screen, and execute the In the present invention, the screen sharing mechanism (2) can be any applicable screen sharing application software, and there are various technologies available for the current commercially available products, which are not described herein. _ 义 system, 妓 明 明 — , , , , , , , , , , 执行 执行 执行 执行 执行 执行 执行 执行 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据Then the right to modify will continue to shut down the computer. However, when it stops executing the operation of the shaft axis modification (that is, the so-called "set") exceeds - timing_ (in order to avoid the constant conversion of control rights, it causes _ _, because ^ is set at this time. Machinery, can __ demand Come _, other participating computer rong or any hardware device 'only Wei _ Taipower _ the same - __, and allow immediate modification of the 1268071 screen /, enjoy the fine", only to verify the right to modify the screen content. * Decided the majority of participants The method of obtaining the 'literature right' can be based on the time of the request. In the present invention, the default value of the right to modify is _««shared operation computer. shouting tree-real money, level use The computer has priority, it can be in the tree of its request, immediately change the secret to the creator, the creator has the highest priority. Such a setting is reasonable. But this control transfer mechanism can also be well recorded. Changed to be able to set the version of the highest priority computer. The following is a schematic diagram illustrating the judgment process of the screen content modification right transfer mechanism of the present invention. Fig. 2 is a flow chart for judging the screen content modification right transfer mechanism. Show, the screen content is modified ⑴ transfer mechanism in ⑽) enabled by first setting the computer P. Have the right to modify the content of the screen. At this time, only the computer p is deleted. The right to modify the contents of the shared computer screen ‘including cursor movement, highlighting, clicking, inputting, editing, etc. Other participant computers are still unable to obtain the request for the repair, and the request is recorded in (10)) and the request is recorded. (10)) The system for modifying the rights of the screen content (1) Calculating the computer that obtained the right to modify at that time The county has exceeded the threshold value when the screen content modification operation is stopped. In this step, 'the threshold value can be set according to actual needs' and can be set directly or accepted by the maker computer. Generally speaking, in the case of an online meeting, the threshold value can be between 2 seconds and 4 seconds, preferably between 2 seconds and 4 seconds. In order to avoid the excessive transfer of control rights, and the system burden, generally 2 seconds is applicable. This will make the operation smoother. If the judgment in step (203) is YES, then (10) in the user's computer that has requested the modification right at the time, the user who first requested the computer is selected from the time when the enabler computer stops modifying the shared computer screen. It obtains the right to modify, and (2(6) transfers the right to modify to the participant's computer, and 1268071 deletes the request to the computerized Kawasaki in (206). In the embodiment of the present invention, the earliest request is obtained. The computer that modifies the right is not the time when the computer that obtained the right to modify exceeds the material, that is, the right to modify is obtained, but the time when the system requests the right to modify, and the time when the computer with the right of modification has been idle, The difference between the two is greater than the previous time - when the right of the computer has been idle, the right to transfer is changed. In another example of the present invention, the enabler computer has priority and can obtain the shared honor screen at any time. The right to modify the content. Therefore, whenever the evangelist computer requests the right to modify the order, it will be revised «transfer to Kaiqi computer, the job acceptance is reasonable. But this control transfer mechanism, It is also very difficult to change the version of the highest priority computer by yourself. (207) 'Check if the operation is over, if yes, then (2〇8), otherwise the operation returns to step (202), continue the above Operation until the end of the operation. The active screen sharing _ of the present invention is a user Pn operating in the sharing of the face and the rights of the reinstatement. The present invention sets P. It has the highest right of modification and can be forced to take office. In addition, the present invention proactively controls the content of the screen to modify the lion transfer, in addition to p. With the highest authority, other users can get the right to modify the content of the screen in a fair competition. It is convenient to share the glory In the system of the screen, it is not necessary to communicate with the user through the user, and the right to modify the content of the screen can be correctly changed. According to the above description, the active computer operation of the present invention for a plurality of people to operate a single computer screen together The control right transfer device and method are the dynamic sharing of the fire-axis conversion-transfer mechanism of the society, and after the computer with the modification right, the ownership of the modification right is judged and transferred. It is not necessary to wait until the computer with the right to modify 1268071 has released the screen of the shared computer screen. After the change of power, it will be transferred. Therefore, it can be __' intuitive and fair to lose (10) Gana control is not made _ The spirit of the shirt, (4) is in the scope. n Lin out of the spirit of the invention, the track is included in its "patent
