Description

Event transmission device, information processing device, information processing system, and event transmission method

The present invention relates to an event transmission device, an information processing device, an information processing system, and an event transmission method.

A system equipped with a plurality of virtual machines operating on a hypervisor displays an image drawn by each virtual machine on its display device in a superimposed manner. When the display device has a touch panel as an input device, the input information received by the touch panel is only the touch coordinates, and thus the system cannot recognize the virtual machine corresponding to the input information.

Therefore, the following two methods are conceivable for the system to transmit input information to an appropriate virtual machine. In one method, the system distributes input information to all virtual machines simultaneously. In another method, the system sequentially sends input information to each virtual machine according to a predetermined order. For example, the system first sends input information to one virtual machine. If one virtual machine receiving the input information does not use the input information, the system transmits the input information to another virtual machine.

JP 2011-197853 A

In the former method, useless communication occurs between the hypervisor and each virtual machine. In the latter method, it takes time from when the input information is input to when a virtual machine that needs the input information receives the input information.

Patent Document 1 proposes a function providing device in which a plurality of virtual machines are mounted on a hypervisor. In this function providing apparatus, a menu screen is displayed on one virtual machine equipped with an OS (operation system) for executing a menu management function. When a specific button corresponding to a specific function is pressed on the menu screen, the menu management function unit of the virtual machine calls a virtual machine that controls the specific function. Therefore, it takes time until the processing request reaches the virtual machine that executes the selected function. Also, the correspondence between the input position on the menu screen and the virtual machine that executes a specific function needs to be determined in advance. That is, the function providing apparatus cannot always execute the same function as the above-described menu management function on an arbitrary display screen.

SUMMARY An advantage of some aspects of the invention is to provide an event transmission device that efficiently transmits an input event to one virtual machine among a plurality of virtual machines operating on a hypervisor. Aim.

The event transmission device according to the present invention transmits an input event to one virtual machine among a plurality of virtual machines operating on the hypervisor. The event transmitting device includes: an input unit configured to receive an input event input to a superimposed image in which a plurality of drawing layers provided for each of the plurality of virtual machines are superimposed; and a plurality of positions in the superimposed image. Event transmission for transmitting an input event to one virtual machine corresponding to an input position of an input event in a superimposed image among a plurality of virtual machines based on a correspondence relationship with one drawing layer from which an image at each of the positions is derived.

<Embodiment 2>
An event transmitting device and an event transmitting method according to Embodiment 2 will be described. The second embodiment is a subordinate concept of the first embodiment. The event transmission device according to the second embodiment includes the components of event transmission device 100 shown in the first embodiment. The description of the same configuration and operation as in the first embodiment will be omitted.

FIG. 5 is a block diagram showing a configuration of the event transmitting apparatus 101 according to the second embodiment. FIG. 5 illustrates a display 110 and a touch panel 120 as devices that operate in association with the event transmission device 101. The event transmission device 101 includes a superimposition unit 50, a display control unit 60, an input unit 10, a layer configuration storage unit 40, an event transmission unit 20, and a plurality of virtual machines 30.

In the second embodiment, the plurality of virtual machines 30 include the first virtual machine 301 to the N-th virtual machine 30N. Each virtual machine runs on a hypervisor.

The superimposition unit 50 superimposes a plurality of drawing layers provided corresponding to each of the plurality of virtual machines 30, and generates a superimposed image. At that time, the superimposition unit 50 first obtains an image drawn by each virtual machine 30. The superimposing unit 50 writes the image on a drawing layer corresponding to each virtual machine 30 from which the image is derived, with reference to the layer configuration relationship. The superimposition unit 50 superimposes the image of each drawing layer to generate a superimposed image. FIG. 6 is a diagram illustrating an example of a layer configuration relationship according to the second embodiment. Here, the layer configuration relationship is a table in which the drawing layer numbers are associated with the virtual machines to be used. The used virtual machine is the virtual machine 30 from which the image to be written in the drawing layer indicated in the drawing layer number column is derived. For example, an image drawn by the first virtual machine 301 is written in the drawing layer indicated by the drawing layer number “1”. Alternatively, for example, an image drawn by the second virtual machine 302 is written in the drawing layer indicated by the drawing layer number “2”.

FIGS. 7 and 8 are diagrams illustrating an example of the drawing layer 2 and the superimposed image 5 according to the second embodiment. FIGS. 7 and 8 show two drawing layers 2 and one superimposed image 5 on which the two drawing layers 2 are superimposed to simplify the description. The two drawing layers 2 include a first drawing layer 2A corresponding to the drawing layer number “1” and a second drawing layer 2B corresponding to the drawing layer number “2” in FIG. The first drawing layer 2A is positioned higher than the second drawing layer 2B.

In FIG. 7, the first virtual machine 301 draws the first area 3 on the first drawing layer 2A. The first virtual machine 301 draws, in the first area 3, a button that is an area for receiving an operation by the user, a message for the user, a design in a screen, and the like (neither is shown). The area other than the first area 3 is transparent. On the second drawing layer 2B, the second area 4 is drawn by the second virtual machine 302. The second virtual machine 302 draws, in the second area 4, a button for receiving an operation by the user, a message for the user, a design in the screen, and the like (neither is shown). The area other than the second area 4 is transparent. In the superimposed image 5, the first drawing layer 2A and the second drawing layer 2B are superimposed on each other. The superimposed image 5 includes a first area 3 and a second area 4 derived from each drawing layer 2.

において The same applies to FIG. On the first drawing layer 2A, the first area 3 is drawn by the first virtual machine 301. The area other than the first area 3 is transparent. On the second drawing layer 2B, the second area 4 is drawn by the second virtual machine 302. The area other than the second area 4 is transparent. In the superimposed image 5, a second region 4 of the second drawing layer 2B is drawn in a region where the first drawing layer 2A is transparent. In the area where the first area 3 and the second area 4 overlap, the first area 3 in the first drawing layer 2A is drawn.

In addition, in the second embodiment, the superimposed image 5 and each drawing layer 2 have a plurality of pixels. The number of pixels of the superimposed image 5 and the number of pixels of each drawing layer 2 are the same. In the superimposed image 5, a plurality of drawing layers 2 are superimposed on a plurality of pixels.

{Each pixel in each drawing layer 2 has an alpha channel indicating transparency information in addition to an RGB value indicating color information. The alpha channel is indicated here by an α value. For example, if the α value of a pixel is 1, the pixel is opaque. In that case, a color corresponding to the RGB value is drawn on the pixel in the superimposed image 5. Or, for example, if the α value of a pixel is 0, the pixel is transparent. In that case, a color corresponding to the RGB value is not drawn on the pixel in the superimposed image 5. 7 and 8, the α value of the first region 3 and the second region 4 are both 1 and the α value of the transparent region is both 0. The superimposing unit 50 may generate the superimposed image 5 based on the transparency information (α value) and a predetermined threshold value related to transparency. By appropriately setting the threshold, the superimposing unit 50 can generate the superimposed image 5 in which two or more drawing layers 2 are superimposed in a translucent state.

{Circle around (4)} The superimposing unit 50 generates a correspondence relationship between a plurality of positions in the superimposed image 5 and one drawing layer 2 from which the image at each position is derived. For example, in FIG. 7 or 8, the superimposing unit 50 associates the position of the first area 3 in the superimposed image 5 with the first drawing layer 2A from which the image of the first area 3 is derived. Further, the superimposition unit 50 associates the position of the second area 4 in the superimposed image 5 with the second drawing layer 2B from which the image of the second area 4 is derived.

In the second embodiment, the superimposing unit 50 generates a bitmap as the above correspondence. Here, the bitmap has the same number of pixels as the number of pixels of the superimposed image 5 and each drawing layer 2. That is, a unit of each pixel is applied as each position of the superimposed image 5 which is a corresponding unit in the above-described correspondence relationship.

The bitmap includes information in which the coordinates of one pixel in the superimposed image 5 are associated with one drawing layer 2 from which the one pixel image is derived. When each pixel of each image layer has an α value, the superimposing unit 50 generates a bitmap based on the α value and a predetermined threshold value regarding transparency. FIG. 9 is a diagram illustrating an example of the bitmap 6 according to the second embodiment. The bitmap 6 stores a drawing layer number for drawing each pixel 7. For example, in the bitmap 6 shown in FIG. 9, “1” indicates that the image is derived from the first drawing layer 2A. “2” indicates that the image is derived from the second drawing layer 2B. In the second embodiment, the bitmap 6 is generated separately from the superimposed image 5.

The display control unit 60 controls the display 110 to display the superimposed image 5 generated by the superimposition unit 50.

The display 110 displays the superimposed image 5 under the control of the display control unit 60.

The touch panel 120 is an input device. Touch panel 120 may be a device included in display 110.

The input unit 10 receives an input event input by the touch panel 120 with respect to the superimposed image 5 displayed on the display 110. The input event includes an input position in the superimposed image 5, that is, touch coordinates.

The layer configuration storage unit 40 stores the above-described layer configuration relationship. As shown in FIG. 6, one virtual machine may correspond to a plurality of drawing layers 2, or although not shown, one virtual machine may correspond to only one drawing layer. However, one drawing layer 2 needs to correspond to only one virtual machine.

The event transmission unit 20 specifies one drawing layer 2 from which the image of the area corresponding to the touch coordinates is derived, based on the pixel coordinates corresponding to the touch coordinates and the bitmap 6 generated by the superimposition unit 50. In addition, the event transmission unit 20 specifies the destination virtual machine corresponding to the specified drawing layer 2 based on the layer configuration relationship stored in the layer configuration storage unit 40. Then, the event transmitting unit 20 transmits the input event to the destination virtual machine.

FIG. 10 is a diagram illustrating a relationship between the hardware of the event transmitting apparatus 101 and the hypervisor according to the second embodiment. The event transmitting apparatus 101 has an SoC (System @ on \ Chip) 130 as hardware. The SoC 130 corresponds to the processing circuit described in the first embodiment. That is, the SoC 130 includes the input unit 10, the event transmission unit 20, the plurality of virtual machines 30, the layer configuration storage unit 40, the superimposition unit 50, and the display control unit 60, and implements the function of each functional unit. Further, the SoC 130 receives an input event input from the touch panel 120. Further, the SoC 130 outputs the superimposed image 5 to the display 110. The plurality of virtual machines 30 operate on the hypervisor 140 installed in the SoC 130. Each virtual machine is virtually constructed on the hypervisor 140 by software.

Next, an operation of generating a superimposed image by the superimposition unit 50 will be described. FIG. 11 is a flowchart illustrating an operation of generating a superimposed image according to the second embodiment.

In step S5, the superimposition unit 50 acquires the image drawn by each virtual machine 30 and the layer configuration relationship.

In step S6, the superimposing unit 50 refers to the layer configuration relationship and writes the image to the drawing layer corresponding to each virtual machine 30 from which each image is derived.

In step S7, the superimposing unit 50 superimposes a plurality of drawing layers to generate a superimposed image 5. Through the above steps, the superimposed image 5 is generated.

Next, the operation of generating a bitmap by the superposition unit 50 will be described. FIG. 12 is a flowchart illustrating a bitmap generation operation according to the second embodiment.

In step S10, the superimposing unit 50 prepares the bitmap 6, and initializes the bitmap 6.

にて In step S20, superimposing section 50 acquires superimposed image 5.

In step S30, the superimposition unit 50 determines whether the generation processing of the bitmap 6 has been completed for all the pixels 7 of the superimposed image 5. When the superimposing unit 50 determines that the processing has been completed for all the pixels 7, the bitmap generation operation ends. When the superimposing unit 50 determines that the processing has not been completed for all the pixels 7, step S40 is executed.

In step S40, the superimposing unit 50 determines whether the generation processing of the bitmap 6 has been completed for all the drawing layers 2 of the superimposed image 5. If the superimposing unit 50 determines that the processing has been completed for all drawing layers 2, step S80 is executed. When the superimposing unit 50 determines that the processing has not been completed for all the drawing layers 2, step S50 is executed.

In step S <b> 50, the superimposing unit 50 acquires data of one pixel 7 in one drawing layer 2 that is currently being processed among the plurality of drawing layers 2 of the superimposed image 5. Here, the data of one pixel 7 is an RGBA value. The RGBA value includes an α value as transparent information in addition to an RGB value as color information.

In step S60, the superimposition unit 50 determines whether or not the one pixel 7 satisfies the relational expression of α value ≧ threshold. If the superimposing unit 50 determines that the relational expression is satisfied, step S80 is executed. If the superimposing unit 50 determines that the relational expression is not satisfied, step S70 is executed.

In step S70, the superimposition unit 50 sets the drawing layer 2 to be processed as the next drawing layer 2.

In step S80, the superimposition unit 50 outputs the currently processed drawing layer number to the pixel 7 of the bitmap 6 corresponding to the currently processed pixel 7. When step S80 is executed as a result of the completion of the processing for all drawing layers 2, the drawing layer number currently being processed is the maximum value among the plurality of drawing layer numbers.

In step S90, the superimposing unit 50 sets the pixel 7 to be processed to the next pixel 7. Through the above steps, a bitmap is generated.

Next, the event transmission method will be described. FIG. 13 is a flowchart illustrating an operation of the event transmitting apparatus 101 and an event transmitting method according to the second embodiment.

にて In step S100, input unit 10 acquires the touch coordinates at which the input event has been input.

In step S110, the event transmitting unit 20 acquires the correspondence (bitmap 6) from the superimposing unit 50.

In step S120, the event transmitting unit 20 acquires a drawing layer number based on the touch coordinates and the bitmap 6.

In step S130, the event transmitting unit 20 acquires a layer configuration relationship from the layer configuration storage unit 40.

In step S140, the event transmitting unit 20 selects one virtual machine as a destination virtual machine from a plurality of virtual machines based on the drawing layer number and the layer configuration relationship.

In step S150, the event transmitting unit 20 transmits the input event to the destination virtual machine.

において In a subsequent step, the destination virtual machine executes a process based on the input event. The event transmitting apparatus 101 may output a result related to the processing to the display 110 via the superimposing unit 50 and the display control unit 60.

Further, in the second embodiment, touch panel 120 and display 110 are shown as separate devices from event transmitting apparatus 101, but event transmitting apparatus 101 may have a configuration including touch panel 120 and display 110. Good.

In summary, the event transmitting apparatus 101 according to Embodiment 2 further includes a superimposing unit 50 that superimposes a plurality of drawing layers 2 and generates a superimposed image 5 and a correspondence. Each of the superimposed image 5 and each of the plurality of drawing layers 2 includes a plurality of pixels 7. The superimposed image 5 is an image in which the plurality of drawing layers 2 are superimposed on each of the plurality of pixels 7. The unit of each pixel 7 is applied as each position of the superimposed image 5 which is a corresponding unit in the correspondence relationship.

In addition, the superimposing unit 50 of the event transmitting apparatus 101 according to the second embodiment includes, as the correspondence, the coordinates of one pixel 7 in the superimposed image 5 and one drawing layer 2 from which the image of one pixel 7 is derived. , Is generated. The event transmitting unit 20 transmits an input event to a destination virtual machine based on the bitmap 6.

With such a configuration, the event transmitting apparatus 101 can select one virtual machine corresponding to the input position by using each pixel 7 of the superimposed image 5 as a minimum unit, so that the input resolution is improved.

In the event transmitting device 101 according to the second embodiment, each of the plurality of drawing layers 2 includes transparency information of each of the plurality of pixels 7. The superimposing unit 50 determines one drawing layer 2 from which an image of one pixel 7 is derived based on the transparency information and a predetermined threshold value related to transparency, and thereby the superimposed image 5 and the bitmap 6 And generate

Basically, of the plurality of drawing layers 2, the drawing layer 2 having a transparency of 0% (that is, non-transparency) and positioned at a higher position is visually recognized by the user. In that case, the input event by the user is input to the opaque drawing layer 2. However, the event transmission device 101 according to the second embodiment can process, for example, an input event to the semi-transparent drawing layer 2 because the threshold value can be changed. Further, the threshold value may be set to be dynamically changeable.

(Modification 1 of Embodiment 2)
In the first modification of the second embodiment, each of the plurality of drawing layers 2 further includes color information of each of the plurality of pixels 7. In the operation of generating the bitmap 6 of the first modification, when the α value is 0 and a value other than the α value (for example, an RGB value that is color information) is a specific value, the superimposing unit 50 The drawing layer number currently being processed is output to the pixel 7 currently being processed. That is, when the transparency information of one pixel 7 in one drawing layer 2 is transparent and the color information is a specific color, the superimposition unit 50 compares the coordinates of one drawing layer 2 and one pixel 7 with each other. The associated bitmap 6 is generated. This processing is executed, for example, between step S60 and step S70. Such an event transmitting apparatus can transmit an input event input for a “hidden button” that does not appear in the superimposed image 5 displayed on the display 110 to an appropriate virtual machine.

(Modification 2 of Embodiment 2)
In Embodiment 2 described above, the superimposing unit 50 generates the bitmap 6 separately from the superimposed image 5. The superimposition unit 50 according to the second modification of the second embodiment generates the superimposed image 5 including the bitmap 6. That is, the bitmap 6 indicating the correspondence is embedded in the superimposed image 5.

FIG. 14 is a flowchart illustrating a bitmap generation operation performed by the superimposing unit 50 according to the second modification of the second embodiment.

にて In step S20, superimposing section 50 acquires superimposed image 5.

Steps S30 to S70 are the same as the steps shown in FIG.

In step S81, the superimposing unit 50 embeds the currently processed drawing layer number in the pixel 7 of the superimposed image 5 corresponding to the currently processed pixel 7. For example, when the drawing layer number is from 0 to 7, the drawing layer number is stored in the three least significant bits of a plurality of bits each storing an RGB value.

Step S90 is the same as step S90 shown in FIG.

Then, the event transmitting unit 20 transmits the input event to the destination virtual machine corresponding to the input position based on the bitmap 6 included in the superimposed image 5. The event transmission method is the same as the method shown in FIG.

In the second modification of the second embodiment, the superimposing unit 50 embeds the bitmap 6 in the superimposed image 5 after completing the generation of the superimposed image 5. However, the method of generating and embedding the bitmap 6 is not limited thereto. The superimposition unit 50 may embed the bitmap 6 simultaneously with the generation of the superimposed image 5.

The event transmission device according to the second modification of the second embodiment does not require a storage area necessary for outputting the bitmap 6.

<Embodiment 3>
An event transmitting device and an event transmitting method according to Embodiment 3 will be described. The third embodiment is a subordinate concept of the first embodiment.
