Drawing applications are sometimes used by businesses and consumers to generate drawings and diagrams for various purposes. For example, drawing applications may be used to generate flowcharts, organization charts, block diagrams, or the like for various business purposes. Drawing applications also can be used to generate complex drawings such as architectural drawings, three-dimensional objects, layouts, or the like.
In many instances, users rely upon natively executed drawing programs to create drawings. Users may upload the generated drawings to collaboration sites or share the drawings with other entities via email, websites, or the like. Because drawings applications often require extensive computing power, however, users generally are unable to create drawings at remote locations. Instead, users often take photographs or sketches of these remote locations and return to a home or business to generate the drawings using the natively executed drawing programs.
While web-based drawing programs are available, these drawing programs often provide only rudimentary functionality. Additionally, these drawing programs may be difficult to interact with mobile devices. In particular, users may be required to type commands or use cursors to place and/or move objects within drawings, and users may be unable to interact with drawings using touch interfaces, as such devices may or may not be supported.
It is with respect to these and other considerations that the disclosure made herein is presented.
Concepts and technologies are described herein for touch interactions with a drawing application. In accordance with the concepts and technologies disclosed herein, users can access a drawing application to create, modify, and/or save drawings. According to various implementations, the drawing application can include a natively executed application. In some other implementations, the drawing application can include a web application executed by a server computer and can save the drawing file as markup language data such as hypertext markup language (“HTML”), extensible markup language (“XML”), and/or various scripts, snippets, and/or other executable code. The drawing file can be saved as data that is hosted and/or served by the server computer to a user device such as a slate, smart phone, or other device that can be configured to access the server computer via a communications network such as the Internet, an intranet, or other networks.
The user device can render the data in one or more user interfaces (“UIs”) for display at the user device. In various implementations, the UIs are presented in a touch sensitive display device by an application program such as a web browser, a natively executed mobile application, or a natively executed drawing application that can be used to create, view, modify, and/or save drawings at the user device. The user device can detect touch events occurring at the user device and can interpret the touch events as touch gestures. In particular, the user device can interpret the touch events by determining if the touch gestures intersect a shape or other object in the drawing, and analyze behavior associated with the touch gesture subsequent to the initially registered touch event.
According to one aspect, the user device determines if a touch gesture intersects an object. If the touch gesture does not intersect an object, the user device can determine if any movement is detected. If not movement is detected, the user device can determine if the touch corresponds to a menu option or other UI control for creating a shape, or the like, such as a contact in a shapes toolbar. If not, the touch gesture can correspond to a de-select command to clear selections within the drawing and/or can be disregarded, if desired. If the movement is detected, the user device can determine if the touch gesture corresponds to a pan gesture or a pinch gesture, and can apply the appropriate command to the UI in response to this determination.
According to another aspect, if the touch gesture intersects an object, the user device can analyze the touch gesture to interpret a command intended by the gesture. If the touch gesture is released, for example if the touch gesture corresponds to a tap gesture, the user device can determine if the intersected shape was previously selected. If so, the and if there is no movement, the user device can launch a text editing mode or text edit mode. If movement is detected, the user device can apply a move command to move the touched object to a new location within the UI. If the object previously was not selected, the user device can select the object.
If the touch gesture is not released, the user device can determine if a subsequent touch is detected prior to release of the touch gesture. If a subsequent touch is detected, the user device can determine if the touch corresponds to a touch-right-click gesture, a gesture in which a first finger is brought into contact with a display and a second finger is brought into contact with the display proximate to the first finger. If the touch-right-click gesture is detected, or if no subsequent touch is detected and instead the first contact is held stationary, the user device can display a contextual UI associated with intersected object. If the subsequent touch does not correspond to touch-right-click gesture, the user device can invoke other commands, as will be explained in more detail herein.
It should be appreciated that the above-described subject matter may be implemented as a computer-controlled apparatus, a computer process, a computing system, or as an article of manufacture such as a computer-readable storage medium. These and various other features will be apparent from a reading of the following Detailed Description and a review of the associated drawings.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended that this Summary be used to limit the scope of the claimed subject matter. Furthermore, the claimed subject matter is not limited to implementations that solve any or all disadvantages noted in any part of this disclosure.
The following detailed description is directed to concepts and technologies for touch interactions with a drawing application. According to the concepts and technologies described herein, users can access a web-based drawing application or a natively executed drawing application to create, modify, and/or save drawings as drawing files. The drawing files can be saved in HTML, XML, and/or other languages and/or scripts, snippets, and/or other executable code such as JAVASCRIPT, .asp, or the like. The drawing file can be accessed by various user devices such as slates, tablets, smart phones, or the like.
The user device can render the data in one or more UIs for display at the user device in a touch sensitive display device. In some embodiments, the user device executes an application program such as a web browser to render the data in the UIs, and in other embodiments, the user device can be configured to execute a natively executed drawing application to provide the functionality described herein. As such, while some embodiments of the concepts and technologies disclosed herein are described a using a web browser or the like to interact with a web-based drawing application, it should be understood that that the concepts and technologies disclosed herein for touch interactions with drawing applications can be used to interact with a natively executed drawing application that is executed on a device that includes a touch interface. The user device can detect touch events occurring at the touch sensitive display and can interpret the touch events as touch gestures. In particular, the user device can interpret the touch events by determining if the touch gestures intersect a shape or other object in the drawing, and analyze behavior associated with the touch gesture subsequent to the initially registered touch event. According to various embodiments, the user device can analyze movement, subsequent touches, and whether or not an object intersected was selected when the touch gesture was commenced to interpret the touch gesture.
While the subject matter described herein is presented in the general context of program modules that execute in conjunction with the execution of an operating system and application programs on a computer system, those skilled in the art will recognize that other implementations may be performed in combination with other types of program modules. Generally, program modules include routines, programs, components, data structures, and other types of structures that perform particular tasks or implement particular abstract data types. Moreover, those skilled in the art will appreciate that the subject matter described herein may be practiced with other computer system configurations, including hand-held devices, multiprocessor systems, microprocessor-based or programmable consumer electronics, minicomputers, mainframe computers, and the like.

Various embodiments of the user device 102 are illustrated and described below, particularly with reference to
The user device 102 can be configured to execute an operating system 106 and one or more application programs 108. The operating system 106 is a computer program for controlling the operation of the user device 102. The application programs 108 are executable programs configured to execute on top of the operating system 106 to provide various functionality. According to various implementations, the application programs 108 include, but are not limited to, web browsing programs (“web browsers”), multimedia software, native web-based applications, drawing programs, other applications, or the like. The application programs 108 can be configured to receive or store data 110, to execute various operations with respect to the data 110, and to render various views of the data 110 in one or UIs 112. The UIs 112 can be presented at the user device 102 and/or at other devices.
According to various implementations of the concepts and technologies disclosed herein, the data 110 can correspond to drawing files or drawing data in various formats. In some embodiments, the data 110 can be obtained from a data source such as a database, a datastore, a network storage device, or another data storage device such as a server computer 114 that is operating as part of, or in communication with, the network 104. Because the data 110 can be obtained from almost any source, it should be understood that the illustrated embodiment in which the data 110 is obtained from the server computer 114 is illustrative and should not be construed as being limiting in any way.
The server computer 114 can be configured to execute a drawing application 116 and can be configured to host and/or serve the data 110 to the user device 102 and/or other devices, nodes, and/or networks. According to various embodiments, the data 110 corresponds to a drawing file generated by the drawing application 116. The data 110 can be formatted by the drawing application 116 such that the data 110 can be viewed or modified by a member of the MICROSOFT VISIO family of drawing programs from Microsoft Corporation in Redmond, Wash. Thus, the data 110 can include a file in the .vsd format or other drawing format, if desired.
In some other embodiments, the drawing application 116 corresponds to a web-based drawing application such as a member of the VISIO WEB APPLICATION family of drawing software from Microsoft Corporation in Redmond, Wash. Thus, drawings created using the drawing application 116 can be saved as the data 110, wherein the data 110 can correspond to an HTML file, an XML file, and/or other types of files. The data 110 therefore can include various scripts or snippets such as, for example, JAVASCRIPT, .ASP, and/or other web-based file formats or executable code that, when executed and/or rendered by the application programs 108, represents a drawing. As such, in various implementations of the concepts and technologies disclosed herein, the files represented by the data 110 can include, but are not limited to, files in web-based formats for representing drawings or other types of files. Because the data 110 can include data in the above-described, as well as other formats, it should be understood that this embodiment is illustrative, and should not be construed as being limiting in any way.
The UIs 112 can include, in various embodiments, computer-executable code that, when executed by the user device 102, causes the user device 102 to present a user interface for viewing the data 110, for supporting interactions by users or other entities with the data 110, for allowing users or other entities to interact with the application programs 108 executed by the user device 102, and/or to support viewing and/or otherwise interacting with the data 110. Various embodiments of some illustrative UIs 112 are illustrated and described below, particularly with reference to
According to various embodiments disclosed herein, the user device 102 can be configured to access or receive the data 110 corresponding to a drawing, diagram, flowchart, or other file. The user device 102 can obtain the data 110 from the server computer 114 and store the data 110 at the user device 102 in a memory, a cache, a hard drive, and/or in any other data storage component. The user device 102 also can be configured to display the data 110 in a user interface or screen display such as the UIs 112. According to various embodiments, the UIs 112 are presented on a touch-sensitive and/or multi-touch-sensitive display device associated with the user device 102.
According to various embodiments of the concepts and technologies disclosed herein, the user device 102 can be configured to detect touch events detected at the user device 102, to interpret the touch events as corresponding to one or more commands, and to implement the commands to modify the UIs 112. According to some implementations, the user device 102 can determine if the touch event detected at the user device 102 intersects an object displayed on the display device. As such, the user device 102 can determine if the touch gesture is intended by the user to apply to the workspace in which objects are displayed, or to a particular object. In some embodiments, the user device 102 determines if an object is intersected based upon determining if any portion of a contact area intersects the object and in other embodiments, the user device determines if a center point of the contact area intersects the object. In yet other embodiments, the user device 102 can determine that the contact area intersects the object based upon weighting and probability analysis, even if the contact area does not actually intersect the object.
Based upon determining if the contact area intersects the object or not, the user device 102 can interpret the detected touch. If the touch does not intersect an object, the user device 102 can determine if any movement is associated with the touch and if so, can determine if the command corresponds to a pinch gesture or another gesture such as a gesture for invoking a pan command. The user device also can detect a shape creation command, which is illustrated and described in more detail below.
If the touch intersects an object, the user device 102 can determine if the touch has been released and if subsequent touches have been detected. In some embodiments, subsequent touches can be interpreted as specific gestures and therefore can be analyzed by the user device. The user device 102 also can determine if an object with which the touch intersected was selected prior to the touch. Based upon these and other determinations and analyses, the user device 102 can interpret the touch and invoke various commands. Some of the various gestures and commands that can be used to interact with a drawing application are illustrated and described in more detail below, particularly with reference to

It also should be understood that the illustrated method 200 can be ended at any time and need not be performed in its entirety. Some or all operations of the method 200, and/or substantially equivalent operations, can be performed by execution of computer-readable instructions included on a computer-storage media, as defined herein. The term “computer-readable instructions,” and variants thereof, as used in the description and claims, is used expansively herein to include routines, applications, application modules, program modules, programs, components, data structures, algorithms, and the like. Computer-readable instructions can be implemented on various system configurations, including single-processor or multiprocessor systems, minicomputers, mainframe computers, personal computers, hand-held computing devices, microprocessor-based, programmable consumer electronics, combinations thereof, and the like.
Thus, it should be appreciated that the logical operations described herein are implemented (1) as a sequence of computer implemented acts or program modules running on a computing system and/or (2) as interconnected machine logic circuits or circuit modules within the computing system. The implementation is a matter of choice dependent on the performance and other requirements of the computing system. Accordingly, the logical operations described herein are referred to variously as states, operations, structural devices, acts, or modules. These operations, structural devices, acts, and modules may be implemented in software, in firmware, in special purpose digital logic, and any combination thereof.
For purposes of illustrating and describing the concepts of the present disclosure, the method 200 disclosed herein is described as being performed by the user device 102 via execution of computer executable instructions such as, for example, the application programs 108. It should be understood that devices other than, or in addition to, the user device 102 can be configured to provide the functionality described herein via execution of various application program, modules, and/or other computer executable instructions in addition to, or instead of, the application programs 108. As such, it should be understood that the described embodiment is illustrative, and should not be construed as being limiting in any way.
The method 200 begins at operation 202, wherein the user device 102 detects a touch. It should be understood that prior to the method 200 beginning, the user device 102 can obtain the data 110 and render the data 110 at a display device associated with the user device 102. As such, the method 200 can begin with a user or other entity interacting with the displayed data 110 via a touch command or gesture at a display device used to display one or more of the UIs 112.
In some embodiments, the user device 102 can execute a touch event handler configured to detect, register, track, and interpret touch events. Thus, the user device 102 can be configured to interpret touch events as various gestures including, but not limited to, tap gestures, tap-and-hold gestures, pinch gestures, double tap gestures, touch-right-click gestures, or the like, which are described and illustrated in more detail below, particular with reference to
From operation 202, the method 200 proceeds to operation 204, wherein the user device 102 determines if the touch detected in operation 202 intersects an object. In particular, the user device 102 can determine if a touch event detected in operation 202 is made at a point of the display screen that displays at least a portion of a displayed object such as text, a shape, or the like. Because the user device 102 can be configured to generate the rendered UIs 112, the user device 102 can determine if the touch event occurs at or near the object by comparing a location of the touch event to locations of displayed objects. Because the user device 102 can determine if the touch events intersect objects in other ways, it should be understood that these embodiments are illustrative, and should not be construed as being limiting in any way.
If the user device 102 determines, in operation 204, that the touch event intersects an object, the method 200 proceeds to the functionality illustrated and described below with reference to
In operation 206, the user device 102 determines if any movement is detected with respect to the touch detected in operation 202. Thus, for example, the user device 102 can determine if a tough-drag gesture is detected. A “touch-drag” gesture, also referred to herein as a “touch-and-drag” gesture, can include a touch at a contact point of an input device such as a touch-sensitive screen and movement of the finger, stylus, or other structure (“finger”) used to make the gesture while the finger is left in contact with the input device. Thus, in operation 206, the user device 102 can be configured to determine if the finger associated with the touch detected in operation 202 has moved. Other gestures that may include movement include, but are not limited to, a pinch gesture, a two-fingered pan gesture, a pan gesture, or the like.
If the user device 102 determines, in operation 206, that no movement is associated with the touch, user device 102 can determine that the touch was a stray touch or otherwise was not associated with a command. Thus, the method 200 can end. If the user device 102 determines, in operation 206, that movement is associated with the touch, the method 200 can proceed to operation 208.
In operation 208, the user device 102 determines if the touch and movement detected in operations 202 and 206 corresponds to a pinch gesture. In some embodiments of the concepts and technologies disclosed herein, pinch gestures, even if made at a location that intersects with an object, can be treated in the same way. For simplicity, however,
The user device 102 can determine that the touch and movement correspond to a pinch gesture by analyzing the touch detected in operation 202 and the movement detected in operation 206. The user device 102 can identify a gesture as a pinch gesture by finding two contact points that move toward each other and/or where one of the contact points is moved toward the other. Because pinch gestures can be identified in other ways, it should be understood that this embodiment is illustrative, and should not be construed as being limiting in any way.
If the user device 102 determines, in operation 208, that the touch and movement correspond to a pinch gesture, the method 200 can proceed to operation 210. In operation 210, the user device 102 can apply a zoom command. According to various implementations, the zoom can be applied in at least two ways, namely, a zoom in and/or a zoom out. In some embodiments, the user device 102 can be configured to zoom out the display if a distance between multiple contact points is decreased during the detected movement. Similarly, the user device 102 can be configured to zoom in the display if a distance between multiple contact points is increased during the detected movement. Because the zooming in or out can be performed in response to other types of movements, it should be understood that these embodiments are illustrative, and should not be construed as being limiting in any way.
If the user device 102 determines, in operation 208, that the touch and movement do not correspond to a pinch gesture, the method 200 can proceed to operation 212. In operation 212, the user device 102 can apply a command such as a pan command. Because other commands can be applied instead of, or in addition to, the pan command, it should be understood that this embodiment is illustrative, and should not be construed as being limiting in any way. In some embodiments, the user device 102 can determine if a pan gesture is detected, though this is not illustrated in
From operations 210 and 212, the method 200 proceeds to operation 214. Additionally, the method 200 can proceed to operation 214 if the user device 102 determines, in operation 206, that no movement is associated with the touch detected in operation 202. The method 200 can end at operation 214. As mentioned above, however, the method 200 can proceed to
Turning now to
According to various embodiments, the user device 102 can determine that a touch has been released if the touch detected in operation 202 is released within a specified time period. The specified time period can be varied by user or application settings and/or user configurations. According to some embodiments, the specified time period includes a tenth of a second, a quarter of a second, a half of a second, three quarters of a second, a second, or other time periods. Because these time periods can be configurable, it should be understood that these embodiments are illustrative, and should not be construed as being limiting in any way.
If the user device 102 determines, in operation 216, that the touch detected in operation has not been released, the method 200 proceeds to operation 218. In operation 218, the user device 102 can determine if a subsequent touch has been detected at the user device 102. Thus, if the touch detected in operation 202 continues to be held by a user, the user device 102 can determine if the user has touched the screen or other input device with a second hand, a second finger, a second stylus, or other input mechanism or device in operation 218.
If the user device 102 determines, in operation 218, that a subsequent touch has not been detected, the method 200 proceeds to operation 220, wherein the user device can be configured to display a contextual menu or contextual user interface associate with the object. An example of a contextual user interface that can be displayed in operation 220 is illustrated and described below, particularly with reference to
In operation 222, the user device 102 can determine if the subsequent touch detected in operation 218 corresponds to a right ‘click.’ In particular, various embodiments of the concepts and technologies disclosed herein provide commands for a touch-right-click gesture, which can correspond to a gesture in which a first finger is brought into contact with an input device, and a second finger is subsequently brought into contact with the input device. This gesture can be interpreted by the user device 102 as invoking functionality similar to that invoked by clicking a right mouse button, if desired. An example of a touch-right-click gesture is illustrated and described below with reference to
In operation 222, the user device 102 can determine, based upon an analysis of the subsequent touch and/or the location thereof, if the subsequent touch corresponds to a right ‘click’ as described above. If the user device 102 determines, in operation 222, that the subsequent touch corresponds to a right ‘click,’ the method 200 proceeds to operation 220, and the contextual menu or contextual user interface can be launched or displayed, as explained above. If the user device 102 determines, in operation 222, that the subsequent touch does not correspond to a right ‘click,’ the method 200 can proceed to operation 224.
In operation 224, an alternative command can be invoked. According to various embodiments, the second touch can correspond to the beginning of a pinch command, as explained above, to a second finger for a two finger drag command, to a pivot point for a rotate command, or other input. As such, the user device 102 can determine, in operation 224, what command is indicated, and can invoke that command. From operations 220 and 224, the method 200 can return to operation 214 of
Returning now to operation 216, if the user device 102 determines, in operation 216, that the touch has been released, the method 200 can proceed to operation 226. In operation 226, the user device 102 can determine if the object on which the touch was detected in operation 202 and 204 was previously selected. In other words, the user device 102 can determine if the object was selected when the touch was detected in operation 202.
If the user device 102 determines, in operation 226, that the object was not selected, the user device 102 can select the object, as shown in operation 228. From operation 228, the method 200 can return to operation 214 of
In operation 230, the user device 102 can determine if any movement is detected with the touch detected in operation 202. Thus, for example, the user device 102 can determine if a tough-drag gesture is detected, for example. A “touch-drag” gesture can include a touch at a contact point of an input device such as a touch-sensitive screen and movement of the finger, stylus, or other structure (“finger”) used to make the gesture while the finger is left in contact with the input device. Thus, in operation 230, the user device 102 can be configured to determine if the finger associated with the touch detected in operation 202 has moved. Thus, the functionality described herein with respect to operation 230 can be, but is not necessarily, similar or even identical to the functionality described above with reference to operation 206 of
If the user device 102 determines, in operation 230, that no movement is associated with the touch, the method 200 can proceed to operation 232, wherein the user device 102 can launch a text edit mode. The text edit mode can be launched to allow a user to enter text associated with the object touched in operation 202. In some embodiments, the user device 102 launches a keyboard user interface or other functionality for enabling a user to enter text. An example of a keyboard user interface is illustrated and described below with reference to
In operation 234, the user device 102 can invoke a move command. Thus, the movement detected in operation 230 can be tracked by the user device 102 and applied to the object determined to have been touched in operation 204. Thus, objects can be moved by the touch input. From operations 232 and 234, the method 200 returns to operation 214 of

Although not described or illustrated separately in
In some embodiments, for example, a touch subsequent to the touch that causes selection of the object in operation 228 can cause the user device 102 to display auto-connect options, if available. In some embodiments, auto-connect options can be turned on via options, menus, ribbon UIs, and/or otherwise. If auto-connect options are not enabled, or available, displaying the auto-connect options can be skipped. In some embodiments, auto-connect options can be displayed in a UI display menu or other UI that can hover over or near the selected object, similar in operation and/or presentation to the display of the contextual UI discussed above with reference to operation 220 and illustrated in
In some embodiments, a touch subsequent to the touch that causes display of the auto-connect options, if available, can cause the user device 102 to display the contextual UI discussed above with reference to operation 220. In some embodiments, a touch subsequent to the touch that causes display of the contextual UI as described immediately above can cause the user device 102 to launch a text edit mode as discussed above with reference to operation 232. Additionally, it should be understood that when the user device 102 is in the text edit mode, a tap outside of the text edit box can cause the user device 102 to return the shape or other object to a basic selected state, to a basic selected state with auto-connect options displayed (if available or enabled), and/or to other states. As such, while flow of the method 200 proceeds from operation 226 to operation 230, it should be understood that that various other operations can be performed between operations 226 and 232, and/or after operation 228.
Furthermore, subsequent taps or other touches after operations 228, 232, and/or 234 can cycle through these and/or other options described herein, though such subsequent touches and/or operations are not illustrated and described separately in detail in

In response to detecting the tap gesture on the selected shape 308, the user device 102 can enter a text edit mode for editing text associated with the selected shape 308. As such, the user device 102 can be configured to modify the screen display 300N to show a keyboard UI 340. The user can interact with the keyboard UI 340 as shown in
The screen display 300O also illustrates another feature that can be provided in accordance with the concepts and technologies disclosed herein. Namely, when the shape 308 is selected, the user device 102 can apply a zoom command to enlarge the shape 308, thereby making it easier to read the entered text. In some embodiments, the user device 102 is configured to store a zoom level, a selection, and a panning position when the text editing mode is entered or commenced. The user device 102 can support zooming, panning, and selection during the text editing mode and can be configured to return the UIs 112 to a selection, zoom level, and/or pan position when the text editing mode is exited.
In one contemplated example of the above features, a user can launch the text editing mode with selection of a first shape. Within the text editing mode, the user device 102 can zoom into the first shape, the user can then pan to and select a second shape and enter text for the second shape. Upon exiting the text editing mode, the user device 102 can update the UIs 112 to select the first shape and return the display to a zoom level and pan position that existed when the text editing mode was commenced. It should be understood that this embodiment is illustrative, and should not be construed as being limiting in any way.

According to various embodiments, the two fingered pan gesture can be used to pan the displayed canvas or workspace 306, regardless of whether or not the gesture is completed on top of shapes or not on top of shapes. In some embodiments, users use two fingers to enhance control during panning.

Referring now to
While various gestures and orders of touch events have been described herein, it should be understood that that in some embodiments, a gesture or touch event may not be evaluated until the touch gesture has been released or otherwise completed. In some embodiments, for example, the user device 102 can be configured to monitor a touch input device for a touch-down event, corresponding to initiation of a touch event, and a touch-up event, corresponding to completion or release of the touch event. Thus, the touch-down event can be evaluated to determine if the touch-down event is a primary touch or a secondary touch. If the touch-down event corresponds to a secondary touch, the user device 102 can determine if another gesture already is in process (a pan or zoom, for example), and if so, the secondary touch may be disregarded, may be used to terminate the other gesture, and/or may be used to further interpret the other gesture. Other processing can be completed at the time the touch-up event is detected, if desired, such as determining how much movement is detected, a contact time, objects that are or are not intersected by the touch, or the like. It should be understood that these embodiments are illustrative, and should not be construed as being limiting in any way.
It further should be understood that determinations as to if shapes are intersected or not can occur before a gesture is released, after a gesture is released, or at other times. In some embodiments, for example, a touch-up event is detected before the user device 102 determines if any shapes or other objects have been intersected by the gesture. Thus, the illustrated embodiments are illustrative and should not be construed as being limiting in any way.
