Abstract

Certain implementations of the disclosed technology may include systems and methods for object selection on presence-sensitive devices. According to an example implementation, a method is provided for outputting, by a computing device and for display, a view containing a first selectable object and a second selectable object; initiating a gesture selection mode in response to receipt of a selection gesture; receiving respective indications of a swipe gesture sequence; outputting, for display, an indication that the first and second selectable objects are selected in response to determining that a first portion of the swipe gesture sequence encircled the first and second selectable objects; and outputting, for display, an indication that the first selectable object is selected and the second selectable object is unselected in response to determining that a second portion of the swipe gesture sequence encircled the first selectable object and did not encircle the second selectable object.

Description

BACKGROUND

Device with presence-sensitive input functionality, including touch screen devices, are increasingly becoming more common. Presence-sensitive displays, for example, can be configured to detect the contact of a stylus, or a touch of a user's finger against a screen. Modern presence-sensitive devices and displays, also allow a user to make natural gestures, such as those used in the process of handwriting. Presence-sensitive devices can be used in conjunction with a processor to recognize the user's gesture and the processor may register a corresponding response. For example, a user may perform a long-tap gesture or a double-tap gesture, which may signal the processor to enter a selection mode to allow selection and/or manipulation of the text or objects.

One disadvantage of using a finger or other broad-tipped stylus device in conjunction with a presence-sensitive device is that it can be difficult to target accurately and select accurately the desired text or object. In systems that have a presence-sensitive input device combined with a display, it can be difficult to accurately target and highlight displayed text or objects so that they may be selected and/or manipulated. In addition, if a user begins selecting an unintended portion of text or object, it can be inconvenient to make corrections, and modifications to correct the mistakenly selected text or object usually require another gesture or repeating the initial gesture.

DETAILED DESCRIPTION

Some implementations of the disclosed technology will be described more fully hereinafter with reference to the accompanying drawings. This disclosed technology may, however, be embodied in many different forms and should not be construed as limited to the implementations set forth herein.

Example implementations of the disclosed technology provide systems and methods for selecting objects associated with a graphical user interface. Certain implementations may further provide convenient methods for refining the selection of objects, for example, to exclude objects that were selected by mistake, or to include additional objects. An illustrative example of the disclosed technology may be utilized with computing devices having a combined display screen and presence-sensitive device, such as a touch screen. Implementations of the disclosed technology may also be used to enable presence-sensitive devices (such as depth cameras, for example) that are not necessarily combined or physically attached to a display screen.

In the example of the touch screen, an according to an example implementation, a user's finger or stylus may be used to initiate an object selection mode, for example, by a quick double tap, or a tap and hold, etc. In an example implementation, after the selection mode has been initiated, respective indications of a swipe gesture sequence may be received to indicate a desired selection of objects that are displayed on the screen. In one example implementation, a diagonal swipe, or a full or partial ellipse-shape swipe gesture may cause a selection (and highlighting) of all objects that are circumscribed or bisected by the swipe gesture. According to an example implementation of the disclosed technology, if some of the selected objects were mistakenly selected, and/or if additional objects are desired for selection, a continued and/or subsequent ellipse-shape swipe gesture, tap, diagonal swipe, etc., may be utilized to refine the set of objects that were initially selected.

In the following description, numerous specific details are set forth. However, it is to be understood that implementations of the disclosed technology may be practiced without these specific details. In other instances, well-known methods, structures and techniques have not been shown in detail in order not to obscure an understanding of this description. References to “one implementation,” “an implementation,” “example implementation,” “various implementations,” etc., indicate that the implementation(s) of the disclosed technology so described may include a particular feature, structure, or characteristic, but not every implementation necessarily includes the particular feature, structure, or characteristic. Further, repeated use of the phrase “in one implementation” does not necessarily refer to the same implementation, although it may.

Throughout the specification and the claims, the following terms take at least the meanings explicitly associated herein, unless the context clearly dictates otherwise. The term “or” is intended to mean an inclusive “or.” Further, the terms “a,” “an,” and “the” are intended to mean one or more unless specified otherwise or clear from the context to be directed to a singular form.

In some instances, a computing device may be referred to as a mobile device, mobile computing device, a mobile station (MS), terminal, cellular phone, cellular handset, personal digital assistant (PDA), smartphone, wireless phone, organizer, handheld computer, desktop computer, laptop computer, tablet computer, set-top box, television, appliance, game device, medical device, display device, or some other like terminology. In other instances, a computing device may be a processor, controller, or a central processing unit (CPU). In yet other instances, a computing device may be a processor combined with one or more additional hardware components.

Various techniques described herein may be used to perform configurable gestures in a graphical user interface. The various aspects described herein are presented as methods, devices (or apparatus), systems, and articles of manufacture that may include a number of components, elements, members, modules, nodes, peripherals, or the like. Further, these methods, devices, systems, and articles of manufacture may include or not include additional components, elements, members, modules, nodes, peripherals, or the like.

In some instances, a graphical user interface may be referred to as an object-oriented user interface, an application oriented user interface, a web-based user interface, a touch-based user interface, or a virtual keyboard. A presence-sensitive input device, as discussed herein, may be a device that accepts input by the proximity of a finger, a stylus, or an object near the device. Additionally, a presence-sensitive input device may be combined with a display to provide a presence-sensitive display. For example, a user may provide an input to a computing device by touching the surface of a presence-sensitive display using a finger. In another example implementation, a user may provide input to a computing device by gesturing without physically touching any object. For example, a gesture may be received via a video camera or depth camera.

In some instances, a presence-sensitive display can have two main attributes. First, it may enable a user to interact directly with what is displayed, rather than indirectly via a pointer controlled by a mouse or touchpad. Secondly, it may allow a user to interact without requiring any intermediate device that would need to be held in the hand. Such displays may be attached to computers, or to networks as terminals. Such displays may also play a prominent role in the design of digital appliances such as the personal digital assistant (PDA), satellite navigation devices, mobile phones, and video games. Further, such displays may include a capture device and a display.

According to one example implementation, the terms computing device or mobile computing device, as used herein, may be a CPU, or conceptualized as a CPU (for example, the processor 302 of FIG. 3). In certain example implementations, the computing device (CPU) may be coupled, connected, and/or in communication with one or more peripheral devices, such as display, navigation system, stereo, entertainment center, Wi-Fi access point, etc. In another example implementation, the term computing device or mobile computing device, as used herein, may refer to a mobile computing device, such as a smartphone, mobile station (MS), terminal, cellular phone, cellular handset, personal digital assistant (PDA), smartphone, wireless phone, organizer, handheld computer, desktop computer, laptop computer, tablet computer, set-top box, television, appliance, game device, medical device, display device, or some other like terminology. In an example embodiment, the mobile computing device may output content to its local display and/or speaker(s). In another example implementation, the mobile computing device may output content to an external display device (e.g., over Wi-Fi) such as a TV or an external computing system.

Furthermore, the various aspects described herein may be implemented using standard programming or engineering techniques to produce software, firmware, hardware, or any combination thereof to control a computing device to implement the disclosed subject matter. The term “article of manufacture” as used herein is intended to encompass a computer program accessible from any computing device, carrier, or media. For example, a computer-readable medium may include: a magnetic storage device such as a hard disk, a floppy disk or a magnetic strip; an optical disk such as a compact disk (CD) or digital versatile disk (DVD); a smart card; and a flash memory device such as a card, stick or key drive. Additionally, it should be appreciated that a carrier wave may be employed to carry computer-readable electronic data including those used in transmitting and receiving electronic data such as electronic mail (e-mail) or in accessing a computer network such as the Internet or a local area network (LAN). Of course, a person of ordinary skill in the art will recognize many modifications may be made to this configuration without departing from the scope or spirit of the claimed subject matter.

As used herein, unless otherwise specified the use of the ordinal adjectives “first,” “second,” “third,” etc., to describe a common object, merely indicate that different instances of like objects are being referred to, and are not intended to imply that the objects so described must be in a given sequence, either temporally, spatially, in ranking, or in any other manner.

Presence-sensitive devices, such as touch screens, generally include a touch-sensitive layer that overlays a display monitor or screen. Various methods may be utilized to detect an input and its relative position on the on a touch screen. One method, according to an example implementation, may utilize sensors and circuitry to monitor changes in a particular state. Other embodiments may monitor changes in electrical currents or reflection of waves. For example, when a user places a finger or a stylus on the screen, the contact or proximity to the screen may induce a change that may be monitored, and a processor may interpret the induced change as an input that may then be acted upon.

Typical touch screens use a layer of capacitive material to hold an electrical charge; touching the screen changes the amount of charge at a specific point of contact. The capacitive material may be based on a two-dimensional coordinate grid (X-axis, Y-axis). The areas that are touched may create a voltage, which may then be detected as having a particular location on the coordinate grid. Specific examples of touch screen materials may include mutual capacitance, which utilizes two distinct layers of material for sensing touch and driving a voltage or current. Another example is self-capacitance, which uses one layer of individual electrodes connected to capacitance-sensing circuitry. The examples of underlying touch screen technology are for example purposes only and will be omitted from further discussion.

In general, the processor and associated operating system may detect and analyze the received touch input and provide a result based on the type of input. For example, when a user touches a touch screen surface, the processor may detect data as a position if the initial touch, the trajectory/pattern of a swipe, taps, and other gestures. In an example embodiment, the processor may utilize software stored in memory to interpret the data as commands and gestures. Input received from the touch screen may be sent to the processor as electrical impulses. The processor may utilize software to analyze the data and determine the characteristics of each touch gesture, such as the size, shape and location of the touched area on the display touch screen.

According to an example implementation of the disclosed technology, analysis software may be used to determine the type of gesture received by the touch screen. For example, a double-tap gesture made with one finger may be used to initiate a selection mode, which enables selection of content. In an example implementation, a second swipe gesture, following the double tap gesture may be used to determine the content that is selected. A swipe gesture may be in the form of a shape, wherein the content within the shape may be selected. Alternatively, the swipe gesture may be in the form of an incomplete shape or linear plane, in which the analysis software may estimate the targeted selection area and select the content within that area. In addition, the second swipe gesture may be used to modify the area to be selected by continuing the swipe gesture and moving the finger to another area of content to be selected.

Various gestures may be utilized for controlling the selection of and interaction with content, according to example implementations of the disclosed technology, and will now be described with reference to the accompanying figures.

FIG. 1A is an illustration of an example display view before and after performing a double tap gesture immediately followed by a swipe gesture, according to an example implementation of the disclosed technology. In this example, the content area(s) of the touch screen device may be organized into a plurality of rows representing separate sections of a display area. Selection, according to an example implementation, may be performed by using one finger and performing a double tap gesture immediately followed by a swipe gesture around the targeted selection area. For example, a user may begin by using an index finger, or any other finger, and performing a double tap gesture on the display. The double tap gesture may be on any portion of the display device and the time between the first and second tap should be some appreciable time apart, such as 1 second or less. In this example, the user may initiate the double tap gesture with a finger at point “A” on the display area 102A. The second on-screen swipe gesture may be performed immediately thereafter and may end at point “B” on the display area 102A. Although the position of points “A” and “B” are illustrated as being off the display area 102A, generally, the user would place their fingers on the display area directly.

Display area 102A provides a view of seven different rows of content at a first time T1 prior to user manipulation. The rows may be predefined sizes of content created by the application and executed by the operating system to provide an aesthetic viewing experience for the user. In this example, rows 1, 2, 3, 4, 5, 6 and 7 are seven rows each containing a certain amount of viewable content. The content of rows 1-7, in this example, may be filled with text and images, which may be, for example, snippets or portions of content from a website. In an example embodiment, the user may execute accessing a website address on their computing device (smartphone, PDA, tablet, personal computer, laptop, etc.), and, as a result, the list of messages 1-7 may be displayed to occupy the display area of the computing device.

Upon performing the double tap gesture at position “A” and performing a swipe gesture ending at position “B” across the surface of the display in a circular motion (as indicated by the arrows), a selection procedure may be performed to select content area 102B. In an example embodiment, The user may indicate to the display device, and by the gesture that the area enclosed by the circular swipe gesture is of interest to the user and should be selected. In an example implementation, the selected view portion (as indicated by the hatch lines in FIG. 1A, lines 1-3) may then be manipulated by the user, for example, to perform general electronic editing operations, such as cut, copy and paste.

FIG. 1B is an illustration of an example display view before and after performing a double tap gesture immediately followed by a swipe gesture, according to an embodiment. In this example implementation, selection may be initiated by using a finger or stylus and performing a double tap gesture immediately followed by a swipe gesture intersecting the content area. For example, a user may begin by using an index finger, or any other finger, and performing a double tap gesture on the display. The double tap gesture may be on any portion of the display device and the time between the first and second should be some appreciable time apart, such as 1 second or less. In this example, the user may initiate the double tap gesture with a finger at point “A” on the display area 102A. The second on-screen swipe gesture may be performed immediately thereafter and ends at point “B” on the display area 102B. Although the position of points “A” and “B” are illustrated as being off the display area 102B, generally, the user would place their fingers on the display area directly.

Upon performing the double tap gesture at position “A” and performing a swipe gesture ending at position “B” across the surface of the display in a linear motion (as indicated by the arrows), a selection procedure may be performed to select content area 102B (as indicated by the hatch lines in lines 1-3). The coordinates of position “A” and “B” may be utilized to calculate the selection area boundary of the target area. The coordinates of “A” may first be computed to determine the start position of the resulting selected area bounding region. The coordinates of “B” may then computed along with the coordinates of “A” to estimate the selection area boundary to be created. In an example embodiment, the user may indicated to the display device that the estimated area enclosed by the computations of positions “A” and “B” is of interest and should be selected. In an example implementation, the selected view portion (as indicated by the hatch lines in FIG. 1B, lines 1-3) may then be manipulated by the user, for example, to perform general electronic editing operations, such as cut, copy and paste.

FIG. 2 is an illustration of an example computer system in which embodiments may be implemented.

In operation, the touch screen input device or display device 210 may receive a first user input double tap gesture followed by second user input swipe gesture. Both user inputs may be analyzed by gesture analyzer 206, which may initiate a selection mode based on the received inputs. The second user input swipe gesture may be received and transferred from the display device 210 to the selection generator 208, which may utilize a processor and operating system to perform computations necessary to select the content area within the path of the second on screen swipe gesture. The subsystem components, such as, the input receiver 204, gesture analyzer 206, and/or selection generator 208 may perform computational functions related to the operation of the processor and operation system to produce the selected content output, as for example, the embodiments described above.

As mentioned above, the display interface 304 may be in communication with the network connection interface 312, for example, to provide information for display on a remote display that is not directly connected or attached to the system. In certain implementations, a camera interface 314 is provided that acts as a communication interface and provides functions for capturing digital images from a camera. In certain implementations, a sound interface 316 is provided as a communication interface for converting sound into electrical signals using a microphone and for converting electrical signals into sound using a speaker. According to example implementations, a random access memory (RAM) 318 is provided, where computer instructions and data may be stored in a volatile memory device for processing by the computer processor 302.

According to an example implementation, the computing device 300 includes a read-only memory (ROM) 320 where invariant low-level system code or data for basic system functions such as basic input and output (I/O), startup, or reception of keystrokes from a keyboard are stored in a non-volatile memory device.

In accordance with an example implementation, the processor 302 has appropriate structure to be a computer processor. In one arrangement, the computer processor 302 may include more than one processing unit. The RAM 318 interfaces with the computer bus 334 to provide quick RAM storage to the processor 302 during the execution of software programs such as the operating system application programs, and device drivers. More specifically, the processor 302 loads computer-executable process steps from the storage medium 322 or other media into a field of the RAM 318 in order to execute software programs. Data may be stored in the RAM 318, where the data may be accessed by the computer processor 302 during execution. In one example configuration, the device 300 includes at least 128 MB of RAM, and 256 MB of flash memory.

In this example implementation, the computing device (processor) may be coupled, connected, and/or in communication with one or more peripheral devices, such as display. In another example implementation, the term computing device, as used herein, may refer to a mobile computing device, such as a smartphone or tablet computer. In this example embodiment, the computing device may output content to its local display and/or speaker(s). In another example implementation, the computing device may output content to an external display device (e.g., over Wi-Fi) such as a TV or an external computing system.

FIG. 4A illustrates an example computing device 401, which may include a touch screen 402 configured to accept user input via touching operations performed by a user's fingers or other instrument. For example purposes, a touch sensor grid 403 is illustrated in an exploded view of the touch screen 402 with a touch sensor grid 403 overlaying the display area. The touch sensor grid may include many touch sensitive areas or cells which may be used to locate the area closest to the input of a user's touch.

FIG. 4B illustrates an example of the touch sensor grid 403 in greater detail. The grid as shown has a two-dimensional touch surface as denoted by the X and Y axes. A first content area 404A at first time T1 is illustrated by the dashed line 406. For example, after a selection of the targeted area 404A of the display is made by performing a first double tap gesture, immediately followed by a second swipe gesture, the content area 404A may be surrounded by a dashed line 406, electronically representing the path of the second swipe gesture. As shown in this example, the path of the second swipe gesture may be in the form of a circle enclosing content area 404A, indicating the content within content area 404A to be selected. Although the example illustrates the second swipe gesture as a circle, the second swipe gesture may be in the form of any shape that encompasses the targeted content area. According to an example embodiment, the system 202 (as shown in FIG. 2) and/or the computing system 300 as shown in FIG. 3 may be utilized to interpret the user's swipe operation and select the specified content area.

FIG. 4C illustrates another example of the touch sensor grid 403 in greater detail. For example, content area 404B at first time T1 may be selected by a linear swipe, as illustrated by the dashed line 408. After the user has selected the targeted area of the display, by performing a first double tap gesture, immediately followed by a second swipe gesture, the content area 404B may be intersected by a dashed line 408, electronically representing the path of the second swipe gesture. The path of the second gesture may be in the form of a line beginning and ending at two points to define content area 404B for selection. The selection area boundary may be calculated using the beginning and ending coordinates of the swipe gesture, and content within content area 404B may be selected. Although the example illustrates the second swipe gesture as a line, the second swipe gesture may be in the form of any incomplete shape that encompasses or intersects the targeted content area. According to an example embodiment, the system 202 (as shown in FIG. 2) and/or the computing system 300 as shown in FIG. 3 may be utilized to interpret the user's swipe operation and select the specified content area.

FIG. 4D illustrates another example of the touch sensor grid 403 in greater detail. For example, a first content area 404A and a second content area 404B will be discussed. In an example embodiment, a target area may be selected by a double tap gesture followed by a second swipe gesture. In this example, the second content area 404B (which may not be desired for selection) is enclosed by a dashed line 410 representing the path of the second swipe gesture. The path of the second gesture, in this example, is in the form of a circle enclosing both the first content area 404A and the second content area 404B. In an example embodiment, if the second content area is not desired for selection, the second gesture may continue to correct the targeted selection area by continuing the swipe gesture in a path that encloses only content area 404A, as indicated by the second dashed line 412. In this example embodiment, the content within first content area 404A may be selected, while that of the second content area 404B may be unselected. This example embodiment illustrates a correction method of the disclosed technology that may eliminate a number of correction steps when compared with traditional methods. According to an example embodiment, the system 202 (as shown in FIG. 2) and/or the computing system 300 as shown in FIG. 3 may be utilized to interpret the user's swipe operation and select the specified content area and deselect an area that was mistakenly selected.

According to an example implementation of the disclosed technology, certain aspects or characteristics of the swipe gesture may be monitored and interpreted to provide further control. In one implementation, a curvature of a gesture may be measured by the computing device and utilized to differentiate a text selection initiation from a scroll initiation gesture. In an example implementation, a gesture may comprise a series of time-sampled points in an X-Y coordinate system that may, for example, be representative of points that the user's finger swipes over the touch screen. In an example embodiment, for each newly sampled point (or series of points, an approximating spline representation of the swipe may be updated. According to an example implementation, if the curvature of the spline exceeds a predetermined threshold, then the gesture may be interpreted as initiating a text selection and the user interface may reflect this interpretation accordingly by switching to a selection mode. In one example implementation, a cursor or other indicator may change to signal that a text selection mode has been entered. Conversely, if the curvature of the spline is determined to be below a predetermined threshold, then the gesture may be interpreted as initiating a swipe, or other screen control gesture. In one example implementation, a cursor or other indicator may change to signal that a screen control mode has been entered

FIG. 5 is an illustration of a flow diagram of an example method 500, according to an example embodiment. In block 502, the method 500 includes outputting for display, a view including a first selectable object and a second selectable object. In block 504, the method 500 includes receiving an indication of a selection gesture. In block 506, the method 500 includes initiating a gesture selection mode in response to receipt of the selection gesture. In block 508, the method 500 includes receiving respective indications of a swipe gesture sequence. In block 510, the method 500 includes outputting, for display, an indication that the first selectable object is selected in response to determining that a first portion of the swipe gesture sequence encircled the first selectable object. In block 512, the method 500 may include outputting, for display, an indication that the first selectable object and the second selectable object are selected in response to determining that a first portion of the swipe gesture sequence encircled the first selectable object and the second selectable object. In block 514, the method 500 may include outputting, for display, an indication that the first selectable object and the second selectable object is selected in response to determining that a second portion of the swipe gesture sequence encircled the first selectable object and the second selectable object. In block 516, the method 500 may include outputting, for display, an indication that the first selectable object is selected and the second selectable object is unselected in response to determining that a second portion of the swipe gesture sequence encircled the first selectable object and did not encircle the second selectable object.

Certain embodiments may include determining that the swipe gesture sequence encircled a selectable object comprises determining that the gesture encircled at least a threshold portion of the selectable object. In certain example implementations, receiving the selection gesture sequence may include receiving respective indications of a first tap gesture and a second tap gesture of a double tap gesture sequence, wherein a first elapsed time between the first tap gesture and the second tap gesture of the double tap gesture sequence is within a predetermined time duration range. Certain embodiments may include outputting, by the computing device and for display, a view displaying a detected path of the swipe gesture sequence.

Certain example implementations of the disclosed technology may include receiving respective indications of a swipe gesture sequence comprising indications of an open shape swipe gesture; and outputting, for display, an indication that the selectable objects correspond to the path of the open shape swipe gesture. Certain example implementations may include detecting a curvature and trajectory of the swipe gesture sequence to distinguish object selection functions associated with the swipe gesture sequence from view navigation functions.

An example embodiment may include outputting, by the processor of the computing device and for display at the presence-sensitive screen, a view highlighting the selected one or more selectable objects. An example embodiment may include outputting, by the processor of the computing device and for display at the presence-sensitive screen, a view displaying the detected path of the swipe gesture. An example embodiment may further include determining a second elapsed time between receiving the indication of double tap gesture and receiving the indication of the swipe gesture, and terminating the initiated gesture selection mode when the second elapsed time is greater than a second predetermined time duration.

In one example embodiment, the swipe gesture may include a first closed shape, and wherein selecting the one or more of the selectable objects comprises selecting selectable objects enclosed within the first closed shape. In an example embodiment, the swipe gesture may further include a second closed shape, and wherein selecting the one or more of the selectable objects includes selecting selectable objects enclosed within the second closed shape and deselecting selected objects that are not enclosed by the second closed shape.

According to one example embodiment, the swipe gesture may be an open shape, and selecting the one or more of the selectable objects may include selecting selectable objects that correspond to the path of the swipe gesture. For example, in one embodiment, a diagonal swipe in a certain region of a presence-sensitive screen may cause selection of objects within a circle or rectangle that is bisected by the swipe. In another example embodiment, the path of the open shape may “touch” certain objects to indicate selection.

In one example embodiment, curvature and/or trajectory of the path of the second sequence of input events corresponding to the swipe gesture may be determined to further identify the swipe gesture and/or distinguish the swipe gesture from other common input that may be provided by the user. For example, this embodiment may help distinguish a selection gesture from a scrolling gesture.

In one embodiment, selecting an area enclosed or covered by the path of the swipe may include calculating a selection area boundary, wherein the boundary is defined by the path of the second on screen gesture and displaying selection markers around the selection area boundary. In another embodiment, the selection may be adjusted by a continuation of the second on screen gesture. For example, a finger or stylus may continue the second on screen gesture without lifting and the selection area boundary may be adjusted to correspond to the new path detected by the continuation of the second on screen gesture. In an example embodiment, this may be performed by selection generator 208 of content selection system 202.

According to example implementations, certain technical effects can be provided, such as creating certain systems and methods that provide enhanced object selection and/or deselection functions for use with presence-sensitive displays.
