The computer in the present embodiment temporarily stores, in the main memory, the program recorded on a portable recording medium or transferred from a server, for example. The computer uses a processor to read the program stored in the main memory and executes processing with the processor in accordance with the read program. The computer may read the program directly from the portable recording medium and execute processing in accordance with the program. Each time the program is received from an external server, the computer may sequentially execute processing in accordance with the received program. Processing may be executed by an application service provider (ASP) type of service that implements functions only via execution instructions and result acquisition, without transmission of the program from an external server to the computer. Examples of the program include an equivalent to the program represented as information provided for processing by an electronic computer. For example, data that is not a direct command for a computer but that has the property of specifying processing by the computer corresponds to the “equivalent to the program”.

A portion or all of the functions of the information processing apparatus 30 may be implemented by a dedicated circuit corresponding to the controller 31. In other words, a portion or all of the functions of the information processing apparatus 30 may be implemented by hardware.

FIG. 2 illustrates an example of a user interface displayed on the display 35 of the information processing apparatus 30. The user operates the input interface 34 of the information processing apparatus 30 to access the server 20 via a web browser, for example. The user then develops software by combining a plurality of development components on the user interface displayed in the web browser. It is thus not necessary in the present embodiment to install, on the information processing apparatus 30, an application or the like that is specialized for the system 10 for providing a software development environment. In other words, as long as the information processing apparatus 30 includes a web browser application, the user can develop software by connecting to the server 20 from the information processing apparatus 30.

The user interface 200 illustrated in FIG. 2 includes a builder area 210, a development component selection area 220, and a property area 240. The builder area 210 is an area for a plurality of development components to be placed, connected, and the like. The user develops software by combining a plurality of development components in the builder area 210. The builder area 210 includes an overview screen 211. The overview screen 211 displays an overview of the placed development components using a reduced-size screen. In other words, the overview screen 211 is a screen displaying all of the placed development components at a reduced size. The range displayed by the builder area 210 (display area) is indicated in the overview screen 211 by a display range frame 212. The display area of the builder area 210 can be expanded or reduced by magnification adjustment tools 213 to 215. The development component selection area 220 is an area for displaying a plurality of development components 221 to 235 that are placeable in the builder area 210. The property area 240 is an area for displaying and editing setting information and the like pertaining to a development component selected in the builder area 210.

The development components in the present embodiment are classified into types such as trigger, action, connector, and logic. The development components 221 to 225 illustrated in FIG. 2 are classified as triggers. The development components classified as triggers are components pertaining to the occurrence of some sort of event, such as the acquisition of a sensor value from a sensor such as a temperature sensor, humidity sensor, or pressure sensor, the elapse of a predetermined length of time, or the occurrence of a predetermined alarm on a device. The development components 226 to 230 are classified as actions. The development components classified as actions are components pertaining to an operation, processing, or the like, such as calculation processing, notification, or uploading of data, that is performed when an event occurs. The development components 231 to 233 are classified as connectors. The development components classified as connectors are components pertaining to information processing with an external resource, such as connection to a database, device, or the like and the addition, updating, deletion, etc. of information thereon. The development components 234 to 235 are classified as logic. The development components classified as logic are components pertaining to the logical sum, filtering, or the like of input information. The user manipulates a mouse pointer or the like to develop software on the user interface 200. For example, the user manipulates a mouse pointer to select a desired development component from the development component selection area 220 and then places, connects, etc. the selected, desired development component in the builder area 210.

FIG. 3 is a diagram illustrating a trigger selection dialog box in the system for providing a software development environment according to an embodiment of the present disclosure. A trigger selection dialog box 250 illustrated in FIG. 3 is displayed when no development component has been placed in the builder area 210. The trigger selection dialog box 250 is a dialog screen for the user to select a development component to place first in the builder area 210. In other words, the user is prompted by the trigger selection dialog box 250 to perform the first operation necessary for software development. The user can thereby easily start developing software. The trigger selection dialog box 250 includes development components 251 to 255, which respectively correspond to the development components 221 to 225 of the development component selection area 220.

FIG. 4 is a diagram illustrating a user interface in which the development component selected in the trigger selection dialog box 250 is placed in the builder area 210. For example, suppose that the user has operated a mouse pointer and selected the development component 251 pertaining to a sensor in the trigger selection dialog box 250. In this case, as illustrated in FIG. 4, a development component 300 corresponding to a sensor is placed in the builder area 210. Properties are associated with the development component 300. The properties include a variety of variables, conditional expressions, setting information, and the like pertaining to the development component. By selecting and setting properties such as various settings, variables, conditional expressions, and so forth from pulldown menus or the like in the property area 240, the user defines various actions and the like for each development component. In other words, the user can develop software by placing and connecting development components and setting the setting information, with no need whatsoever for writing program code.

FIG. 5 is an example in which a plurality of development components has been placed and connected in the builder area 210. In FIG. 5, development components 301 to 311 have been placed and are connected by links 401 to 410. The link 401 indicates that the output of the development component 301 is the input of the development component 305. The link 402 indicates that the output of the development component 302 is the input of the development component 305. The link 403 indicates that the output of the development component 303 is the input of the development component 305. The link 404 indicates that the output of the development component 304 is the input of the development component 306. The link 405 indicates that the output of the development component 305 is the input of the development component 307. The link 406 indicates that the output of the development component 307 is the input of the development component 306. The link 407 indicates that the output of the development component 306 is the input of the development component 308. The link 408 indicates that the output of the development component 306 is the input of the development component 309. The link 409 indicates that the output of the development component 306 is the input of the development component 310. The link 410 indicates that the output of the development component 306 is the input of the development component 311. Properties are associated with each of the development components 301 to 311.

FIG. 6 is a flowchart illustrating operations by the system 10 for providing a software development environment, i.e. an example of a method for providing a software development environment.

First, the controller 31 of the information processing apparatus 30 displays the user interface 200 on the display 35 (step S10). FIG. 5 is an example of the user interface 200 displayed in this case. As described above, the user interface 200 includes the builder area 210 and the development component selection area 220, which displays a plurality of development components placeable in the builder area 210. Here, a request to display the user interface 200 is based on an input operation from the user. For example, the controller 31 uses the input interface 34 to receive an input operation by the user on the web browser. Upon receiving the input operation, the controller 31 communicates with the server 20 via the communication interface 33 and receives data pertaining to the user interface 200. The controller 31 then displays the user interface 200 on the display 35 based on the data. An authentication process or the like pertaining to the user may be performed by the server 20 and the information processing apparatus 30 as appropriate.

Next, the input interface 34 receives an input to select one of the development components 301 to 311 displayed in the builder area 210 (step S20). For example, the input interface 34 receives an input to select the development component 305.

Subsequently, the controller 31 displays links connected to the selected development component in an emphasized display form on the display 35 (step S30). FIG. 7 illustrates an example of the emphasized display form. The links connected to the selected development component 305 are the links 401 to 403 and the link 405. All of these links 401 to 403 and link 405 are displayed with more emphasis than the links not connected to the selected development component 305. Here, the controller 31 may display links connected to the input port of the selected development component and links connected to the output port of the selected development component with emphasis in different colors. The input port of the development component in the present embodiment is the port to which the arrow-shaped end of each link is connected. The output port of the development component is the port to which the opposite end from the arrow-shaped end of each link is connected. In other words, the links connected to the input port of the selected development component are the links 401 to 403. The link connected to the output port of the selected development component is the link 405. For example, the links 401 to 403 are displayed with emphasis in blue. The link 405 is displayed with emphasis in a color other than blue (such as red).

In this way, according to the system 10 for providing a software development environment of the present embodiment, the links connected to a selected development component are displayed in an emphasized display form, as illustrated in FIG. 7, for example. This enables the user to grasp the relationship between development components easily. In other words, the convenience of the user interface of a software development environment can be improved by the system 10 for providing a software development environment in the present embodiment.

As illustrated in FIG. 7, the controller 31 may also display the selected development component (here, the development component 305) with emphasis in addition to the links connected to the selected development component. When the selected development component is also displayed with emphasis, the user can more easily grasp the relationship between development components.

The form of the emphasized display is not limited to this example. For example, the display may be emphasized by appropriately changing any parameter such as brightness, the shade of the display color, or the contrast of the link or development component, or a combination thereof. Apart from changing these parameters, the display may also be emphasized by any form that stands out visually as compared to other links or development components.

The system 10 for providing a software development environment according to the present embodiment achieves a greater effect when a plurality of development components are present in the builder area 210 and have a complex connection relationship. FIG. 8 illustrates an example of the case when the number of placed development components is large. In FIG. 8, the development components 321 to 335 have been placed in the builder area 210. The link 421 indicates that the output of the development component 321 is the input of the development component 326. The link 422 indicates that the output of the development component 321 is the input of the development component 328. The link 423 indicates that the output of the development component 321 is the input of the development component 329. The link 424 indicates that the output of the development component 321 is the input of the development component 335. The link 425 indicates that the output of the development component 322 is the input of the development component 327. The link 426 indicates that the output of the development component 322 is the input of the development component 332. The link 427 indicates that the output of the development component 322 is the input of the development component 334. The link 428 indicates that the output of the development component 323 is the input of the development component 328. The link 429 indicates that the output of the development component 324 is the input of the development component 329. The link 430 indicates that the output of the development component 325 is the input of the development component 330. The link 431 indicates that the output of the development component 326 is the input of the development component 331. The link 432 indicates that the output of the development component 328 is the input of the development component 331. The link 433 indicates that the output of the development component 328 is the input of the development component 333. The link 434 indicates that the output of the development component 328 is the input of the development component 334. The link 435 indicates that the output of the development component 329 is the input of the development component 334. The link 436 indicates that the output of the development component 329 is the input of the development component 334. The link 437 indicates that the output of the development component 330 is the input of the development component 333.

If the number of development components and links increases as in FIG. 8, the connection relationship between development components can become hard to grasp. The controller 31 therefore displays the links connected to a development component with emphasis based on an input to select the development component. FIG. 9 illustrates an example of the development component 328 being selected. In this case, the links connected to the development component 328, i.e. the links 422, 428, 432, 433, 434, are displayed with emphasis. When the links connected to a selected development component are thus displayed with emphasis, the user can easily grasp the relationship between development components.

Furthermore, the controller 31 displays the links connected to a selected development component on the display 35 in a higher-level layer than links not connected to the selected development component. Operability can thereby be improved when an operation to select the links is performed. For example, the case of changing the destination of the link 422, among the links displayed with emphasis in FIG. 9, from the development component 328 to the development component 330 is described with reference to FIGS. 10 to 13. The change in the destination of the link is an operation that may occur during debugging, improvement, or the like of software. An increase in operability increases productivity during debugging, improvement, and the like.

For example, when wishing to change the destination of the link 422, the user selects the link 422, which is displayed with emphasis. The input interface 34 receives this selection operation. FIG. 10 illustrates the link 422 in a selected state. As described above, the link 422 displayed with emphasis is displayed in a higher-level layer than links not displayed with emphasis. Therefore, even if links such as the link 423 overlap the link 422, the overlapping links are not selected by mistake.

FIG. 11 is a drawing representing an operation screen while an end 422′ of the link 422 is being operated to change the destination to the development component 330. The user can change the destination by performing a drag-and-drop operation or the like on the end 422′ of the link whose destination is to be changed.

FIG. 12 illustrates the state after the destination of the link 442 has been changed to the development component 330. FIG. 13 is a diagram illustrating a display example in which the development component 330 is selected. It is clear that the destination of the link 422 has changed to the development component 330.

The basic configuration of a link illustrated in the above embodiment is a combination of horizontal or vertical lines, but this example is not limiting. A link may be a line or a curve, extending horizontally, vertically, or diagonally, or a combination thereof, and the line type of a link may be changeable. FIG. 14 is a diagram illustrating an example of the case of changing the line type of the links in the display example of FIG. 8. Switching the line type of links in this way enables the user to easily grasp the relationship between development components.

The controller 31 may, for example, display the links connected indirectly to a selected development component with emphasis on the display 35. FIG. 15 is a diagram illustrating a display example of the case of emphasizing links connected indirectly to a selected development component. The development component 305 is selected in FIG. 15. In this case, the links connected directly and indirectly to the development component 305 are emphasized. The links connected directly to the development component 305 are the links connected to the input port or the output port of the selected development component 305. In the example in FIG. 15, the links 401 to 403 and the link 405 are directly connected links. The links connected indirectly to the development component 305 are links, other than the directly connected links, that arrive at the selected development component 305 upon following links on the input side or the output side. In other words, the indirectly connected links are links, other than the directly connected links, that connect to a development component connected in series with the development component 305. In the case of the development component 305, the links 406 to 410 all arrive at the development component 305 upon following links on the input side. Accordingly, these links are links connected indirectly to the development component 305. When the indirectly connected links are thus displayed with emphasis, the user can easily grasp which development components are affected by the input and output of a certain development component. Note that the link 404 is not included among the links connected indirectly to the development component 305. The reason is that the development component 305 is not reached from the link 404 upon following links unidirectionally on either the input side or the output side.

The directly connected links and the indirectly connected links may be displayed with emphasis in different forms. In other words, the controller 31 may display the links connected directly to a selected development component and the links connected indirectly to the selected development component with emphasis in different colors on the display 35. For example, when the links 401 to 403 are displayed with emphasis in blue, and the link 404 is displayed with emphasis in red, the links 406 to 410 may be displayed with emphasis in black. This configuration enables the user to easily grasp the relationship between development components in a form that distinguishes between directly connected links and indirectly connected links.

When a plurality of development components placed in the builder area 210 includes a plurality of development components of the same type, the development components of the same type may be displayed by an object that integrates a plurality of development components (integrated object). In other words, a plurality of development components of the same type may be displayed by an integrated object instead of by separate objects. The development components of the same type are development components associated with the same icon and connected to the same destination development component. For example, the icons of the development components 301, 302, 303 placed in the builder area 210 of FIG. 7, described above, are all the same icon (an icon pertaining to a sensor). The development components 301, 302, 303 are all connected to the development component 305. That is, the development components 301, 302, 303 are development components connected to the same destination development component. Accordingly, these development components may be displayed by an integrated object. FIG. 16 illustrates an example of the case of displaying these development components by an integrated object. In FIG. 16, the development components 301, 302, 303 are replaced by an integrated object 501. The integrated object 501 is displayed in a form that includes a corresponding icon (here, an icon illustrating a sensor) to facilitate identification of the type of the integrated development components. The links 401, 402, 403 that connected the respective development components 301, 302, 303 with the destination development component are displayed only by the link 401. When the integrated object 501 is thus displayed, the number of objects and the number of links in the builder area 210 are reduced, enabling the user to easily grasp the relationship between development components.

The integrated object may be displayed in a display form that includes a badge indicating the number of integrated development components. The integrated object 501 in FIG. 16 includes a badge 601. In FIG. 16, three objects are integrated, i.e. the development components 301, 302, 303. The badge therefore indicates “3”. The badge enables the user to easily learn the number of integrated development components.

When the plurality of development components placed in the builder area 210 includes a plurality of development components of the same type, the development components of the same type have been described as being indicated by an integrated object, but this example is not limiting. For example, when the plurality of development components placed in the builder area 210 includes a plurality of development components of the same type, the development components of the same type may be indicated by an integrated object if a predetermined condition is satisfied. The predetermined condition may, for example, be the number of development components placed in the builder area 210, the number of links, the display magnification, or a combination thereof.

The information processing apparatus 30 has been described as accessing the server 20 via a web browser in the present embodiment to provide the user with a software development environment, but this example is not limiting. For example, an application according to the system 10 for providing a software development environment may be installed on the information processing apparatus 30, and a software development environment may be provided to the user by communication with the server 20 via the application.
