DETAILED DESCRIPTION
The discussion below is directed to certain specific implementations. It is to be understood that the discussion below is only for the purpose of enabling a person with ordinary skill in the art to make and use any subject matter defined now or later by the patent “claims” found in any issued patent herein.
It is specifically intended that the claimed invention not be limited to the implementations and illustrations contained herein, but include modified forms of those implementations including portions of the implementations and combinations of elements of different implementations as come within the scope of the following claims. Nothing in this application is considered critical or essential to the claimed invention unless explicitly indicated as being “critical” or “essential.”
Reference will now be made in detail to various implementations, examples of which are illustrated in the accompanying drawings and figures. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. However, it will be apparent to one of ordinary skill in the art that the present disclosure may be practiced without these specific details. In other instances, well-known methods, procedures, components, circuits and networks have not been described in detail so as not to unnecessarily obscure aspects of the implementations.
It will also be understood that, although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first object or step could be termed a second object or step, and, similarly, a second object or step could be termed a first object or step, without departing from the scope of the invention. The first object or step, and the second object or step, are both objects or steps, respectively, but they are not to be considered the same object or step.
The terminology used in the description of the present disclosure herein is for the purpose of describing particular implementations only and is not intended to be limiting of the present disclosure. As used in the description of the present disclosure and the appended claims, the singular forms “a,” “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It will be further understood that the terms “includes,” “including,” “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components and/or groups thereof.
As used herein, the term “if” may be construed to mean “when” or “upon” or “in response to determining” or “in response to detecting,” depending on the context. Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” may be construed to mean “upon determining” or “in response to determining” or “upon detecting [the stated condition or event]” or “in response to detecting [the stated condition or event],” depending on the context.
“Alternatively” shall not be construed to only pertain to situations where the number of choices involved is exactly two, but rather refers to another possibility among many other possibilities.
Additionally, various technologies and techniques described herein include receiving user requests for a number of different operations. In certain instances, the user request for a particular operation will be explicitly described. It shall be understood that “user request” or “user can request” shall also include, but are not limited to, touching the screen, double tapping the screen (tapping the screen twice in rapid succession), pressing a particular physical or virtual button, making a selection from a menu, placement of a cursor at a particular location, stylus pointing, mouse selection, an audible command, as well as the explicit description of the “user request” for the particular operation or how the “user can request”, explicitly, the particular operations.
In one implementation, various technologies and techniques described herein are directed to a display device having a screen. In one implementation, the screen can display sonar images that are currently being captured as well as sonar images that had previously been captured. The sonar images form a stream of sonar images that may be ordered based on time.
In another implementation, while the screen displays sonar images that are currently being captured, the display device may provide the user access to older portions of sonar images that were captured considerably long before the currently captured sonar images. For example, the user may access to these older portions by placing their finger on the screen over the sonar data and swiping in the direction of the most recent sonar image. The sonar images on the screen will move according to the movement of the finger. Sonar images on the right (the most recent) will move off the screen, and the older sonar images will appear on the left hand side of the screen. The user can continue this process (swiping the screen and moving the displayed sonar data) until the sonar images from a desired time appear on the screen.
While the user accesses older sonar images, the display device may continue to record captured sonar images and add them to the sonar image stream. The user can return to viewing the sonar images that are currently being captured. In one implementation, the user can view the sonar images that are currently being captured while the user is viewing older sonar images by swiping the displayed sonar images to the left. When the displayed sonar images are swiped to the left, the oldest sonar images drop off the right hand side and newer sonar images appear on the left hand side. Although various implementations have been described with the most recent sonar images may appear on the right, while older sonar images may appear on the left, in some implementations, the order can be reversed.
The sonar image stream can be quite lengthy and the user may have to search a long time to view a particular sonar image of interest. In some implementations, the display device may provide a preview of the entire sonar image stream in a smaller region of the screen, e.g., a preview pane. The sonar images in the preview pane may be condensed. However, in certain implementations, the condensed sonar images may be large enough for the user to notice some of the significant characteristics. The user can identify the desired sonar image by spotting the significant characteristics in the condensed sonar image stream. To select the desired sonar image for view in more detail in a regular pane, the user can highlight the desired area in the condensed sonar image stream, and the corresponding sonar image in regular size will appear in the regular pane.
FIG. 1 illustrates a block diagram of a display device 100 in accordance with various implementations described herein. The display device includes a screen 105 that provides a graphical user interface for displaying sonar images 110. Sonar images 110 may provide a map of the underlying body of water in the vicinity of a sonar device. The display device 100 may also include a plurality of buttons 112 to facilitate user interaction. The plurality of buttons 112 can be physical buttons (shown) or virtual buttons (not shown). Additionally, the display device 100 can include a speaker/microphone 113.
In certain implementations, the screen 105 can be touch-sensitive or sensitive to the human body heat of a finger. As such, the display device 100 may be able to detect the location of the screen 105 that is touched by the finger (not shown). In some implementations, the display device 100 may provide a cursor 114. The cursor 114 may be movable by placement of the finger over the cursor 114 and dragging the finger to a desired location. The display device 100 may cause the cursor 114 to follow the finger.
The sonar images 110 may be presented as a two-dimensional graphics, where the vertical axis 115 represents depth and the horizontal axis 120 represents time. The graphical user interface may provide a number of tools to allow the user to obtain more specific information. For example, the user can use the cursor 114 for pointing to a particular location in the graphical user interface. In certain implementations, the display device 100 presents the cursor 114 in response to receiving a user request for the cursor 114.
The graphical user interface can provide specific information about the particular location, such as depth 130 and estimated water temperature 132 at the particular location. The graphical user interface can also provide ocean depth 155, estimated water temperature 160, latitude 170 and longitude 175 at a current location of a vessel carrying the display device 100. The graphical user interface can also provide zooming 180 for more detail or more range.
Sonar equipment (not shown) can capture sonar images in real time. The display device 100 is configured to receive the sonar images and record the sonar images to a recording medium (not shown), such as memory, and also provide the sonar images for display on the screen 105 in real time. In one implementation, the newly captured sonar images 110 appear on the rightmost part of the graphic, while the older sonar images 110 appear towards the left. After some time, the older sonar images 110 on the left move off of the screen. By convention, the right side has more recent sonar images 110 while the left side has older sonar images 110. In certain implementations, the foregoing can be reversed.
In some implementations, the recording medium can be part of the display device, while in other implementations, the recording medium can be external to the display device 100. The display device 100 allows the user to access a previously captured and recorded sonar images.
While the user accesses previously recorded sonar images, the display device 100 may continue to record the sonar images that the sonar device captures into memory. The sonar images are stored and available for display. FIG. 2 illustrates a timing diagram showing different times that sonar images are recorded and displayed. Axis 200 indicates time, t0 . . . tn, wherein t0 comes first, t1 comes second, t2 comes third, etc. The sonar images 110 received by the sonar device can be associated with time. For example, at time t4, the user may request the display device 100 to display the sonar images collected at time t0 to t1, which were collected earlier than time t4. The user may review the sonar images collected between time t0 to t1 from t4 to t8 While the user reviews the sonar images at t0 to t1, the sonar images from t4 to t8 are continually being captured and recorded. These sonar images are retrievable for viewing by the user at a later time. For example, at time t8, the user can view sonar images captured at time t6.
The display device 100 may provide the user with at least two ways of requesting access to past sonar images 110. These include a panning mode and a preview mode.
Reviewing Past Sonar Images
A. Panning Mode
FIG. 3 illustrates a schematic diagram of a graphical user interface showing past sonar images 110 by panning. When panning, the user places their finger 305 onto the screen 105 over the sonar images 110 and swipes their finger 305 in a particular direction 310. The sonar images 110 move in the direction of the finger 305. This is known as panning. Certain portions of the sonar images 110 will no longer appear on the screen, while new portions of the recorded sonar images will appear on the screen 105.
For example, swiping the finger 305 to the right provides older sonar images, while swiping the finger 305 to the left provides more recent sonar images. In one implementation, the data will not move to the left if the most recent sonar image 110 is displayed. Additionally, the sonar images 110 will not move to the right once the user reaches the oldest sonar images 110 that are stored. In certain implementations, the user can use one or more of the plurality of buttons 112. For example, some of the plurality of buttons 112 can be associated with directions.
FIG. 4 is a flow diagram for reviewing past sonar images 110 in accordance with various implementations described herein. The flow diagram will be described with references to FIGS. 1-3. At block 405, the display device 100 displays current sonar images 110.
At block 410, the display device 100 receives a user request to move the sonar images 110 backwards, or to view past sonar images 110. The user request may include placement of the finger 305 on the screen 105 and swiping the finger to the right. For example, at time t4, the user may wish to review the sonar images 110 captured at t0.
At block 415, when the finger swipe to the right is finished, the desired past sonar images 110 captured at t0 may be displayed on the screen 105. In one implementation, the display device 100 displays the past sonar images 110 in accordance with the user request, while also recording current sonar images. The display device 100 can display the past sonar images 110 by receiving finger swipes that cause the display device to continuously pan the sonar images 110.
At block 420, the display device 100 receives a user request to review sonar images 110 that were just recorded while the user was viewing past sonar images 110 during blocks 410-415. For example, while the user was reviewing past sonar images t0-t1 during blocks 410-415 at times t4-t8, the display device 100 was recording sonar images captured from times t4-t8. At time t8, the user may wish to review the sonar images captured at time t6. In one implementation, the user request can include swiping the finger to the left. The user may continue swiping/panning until the display device 100 displays sonar images captured at time t6.
At block 425, the display device 100 displays the sonar images 110 requested by the user during block 420, e.g., sonar images captured at time t6.
At block 430, while the user is viewing the sonar images captured at time t6, the display device 100 may receive a user request to display the most current sonar images. This user request may be made for example at time t9. The user request can include swiping the screen to the left until the most recent sonar images 110, i.e., sonar images captured at time t9, are displayed on the display device 100. At block 435, the display device 100 displays the most current sonar images, e.g., t9 . . . tn.
B. Preview Pane
FIG. 5 is a schematic of a graphical user interface with a preview pane 505 in accordance with various implementations described herein. In one implementation, the preview pane 505 displays previously recorded sonar images 110 at a size that is smaller in size to the sonar images 110 displayed in a regular pane 515. In another implementation, the preview pane 505 can include sonar images 110 covering a longer period of time than the regular pane 515. For example, the preview pane 505 can include a condensed version of all the sonar images 110 (condensed sonar images) that have been recorded. The recording medium may have a capacity that limits the time period that the sonar images 110 can be stored. For example, the time period can be about ten minutes. In certain implementations, the preview pane 505 can provide condenses sonar images 110 from the most recent hour. Although the preview pane 505 is described herein as having condensed sonar images, it should be understood that the sonar images may also be in compressed format.
In still another implementation, the preview pane 505 may include a semi-transparent sliding box 510 that identifies the portion of the preview pane 505 representing the sonar images 110 that are shown in the regular pane 515. When the regular pane 515 displays the most current sonar images 110, the sliding box 510 is all the way to the right.
FIG. 6 illustrates viewing past sonar images 110 using the preview pane 505 in accordance with various implementations described herein. In one implementation, the condensed sonar images in the preview pane 505 are smaller than the sonar images 110 in the regular pane 515, but are still large enough for the user to scan and locate notable features. The condensed sonar images in the sliding box 510 are displayed at regular size in the regular pane 515. In one implementation, moving the sliding box 510 moves the sonar images 110 in the regular pane 515 to correspond to the condensed sonar images in the sliding box 510. The user can switch the positions of the sliding box 510 by placing a finger 305 on the desired condensed sonar images in the preview pane 505. Upon placing the finger 305 on the desired condensed sonar images, the sliding box 510 is displayed around that area and the sonar images in regular size that correspond to the desired condensed sonar images are displayed at the regular pane 515.
In certain implementations, when the user places the finger 305 on the sliding box 510 and swipes the sliding box 510, the sonar images 110 in the regular pane 515 freeze until the user releases the sliding box 510. When the user releases the sliding box 510, the sonar images displayed in the regular pane 515 correspond to the condensed sonar images in the sliding box 510.
FIG. 7 is a flow diagram for reviewing past sonar images 110 using the preview pane 505 in accordance with various implementations described herein. At block 705, the display device 100 displays sonar images 110 that are currently captured in a regular pane 515. At block 710, the display device 100 displays condensed sonar images that were previously recorded in the preview pane 505, while displaying currently recorded sonar images 110. At block 715, the display device 100 highlights a first portion of the condensed sonar images on the preview pane 505 with a semi-transparent box, such as sliding box 510. At block 720, the display device 100 displays the sonar images that correspond to the first portion on the regular pane 515 in regular format.
At block 725, the display device 100 may receive a user request to highlight a second portion of the condensed sonar images on the preview pane 505. The user request can include receiving finger contact with the sliding box 510 and swiping the sliding box 510. Alternatively, the user request can include receiving direct finger contact at the second portion of the preview pane 505.
At block 730, the display device 100 highlights the second portion of the condensed sonar images on the preview pane 505. At block 735, the display device 100 displays the sonar images in the regular pane 515 that correspond to the condensed sonar images in the second portion of the preview pane 505.
Modes of Preview Pane Operation
Returning to FIG. 6, the graphical user interface can include a menu 605 with a “Back” selection 610(1), an “Off” selection 610(2), a “Cursor Only” selection 610(3), and an “Always” selection 610(4). In certain implementations, the display device 100 can be multifunctional and provide additional functions to just sonar image presentation. For example, the “Back” selection 610(1) allows the user to leave the sonar image presentation function and access a higher level menu.
In addition, the display device 100 can provide the preview pane 505, based on user selections. For instance, if the user selects the “Off” selection 610(2), the display device 100 does not display the preview pane 505. The user can also request that the display device 100 always display the preview pane 505 by selection the “Always” selection 610(4). In some implementations, the preview pane 505 appears based on whether there is a cursor 114. If there is no cursor 114, the preview pane 505 does not appear. If there is a cursor 114 present, the preview pane 505 appears. The user can request display of the preview pane based on existence of the cursor 114 by selecting the “Cursor Only” selection 610(3).
FIG. 8 is a flow diagram for determining whether to place the preview pane 505 or not. At block 805, the display device 100 determines whether the mode is “Off”, “Always”, or “Cursor Only”. If at block 805, the display device 100 determines that the mode is “Off”, at block 810, the display device 100 does not display the preview pane 505 and returns to block 805. If at block 805, the display device 100 determines that the mode is “Always”, at block 815, the display device 100 displays the preview pane 505 and returns to block 805.
If at block 805, the display device 100 determines that the display device 100 is in “Cursor Only” mode, the display device 100 makes a determination whether the cursor is present (block 820). If the cursor 114 is present, the display device 100 displays the preview pane 505 at block 815 and returns to block 805. If the cursor is not present at block 820, the display device 100 does not display the preview pane 505 (block 815). The display device 100 then returns to block 805.

The screen 905 detects placement and movement of the user's fingers and provides signals that are indicative of such placement and movement to the CPU 930. Additionally, the screen 905 detects user interactions with the objects provided by the GPU 931 and provides signals that are indicative of the user interactions with the objects. The monitor 934 may also be connected to system bus 928 via an interface, such as a video adapter 932.
Further, the computing system 900 may operate in a networked environment using logical connections to one or more remote computers 974. The logical connections may be any connection that is commonplace in offices, enterprise-wide computer networks, intranets, and the Internet, such as local area network (LAN) 976 and a wide area network (WAN) 966. The remote computers 974 may be another computer, a server computer, a router, a network PC, a peer device or other common network node, and may include many or all of the elements describes above relative to the computing system 900. The remote computers 974 may also each include application programs 970 similar to that of the computer action function.
When using a LAN networking environment, the computing system 900 may be connected to the local network 976 through a network interface or adapter 944. When used in a WAN networking environment, the computing system 900 may include a wireless router 964 or other means for establishing communication over a wide area network 966, such as the Internet. The router 964 may be connected to the system bus 928 via the serial port interface 942. In a networked environment, program modules depicted relative to the computing system 900, or portions thereof, may be stored in a remote memory storage device 972. It will be appreciated that the network connections shown are exemplary and other means of establishing a communications link between the computers may be used.
In certain implementations, the computing system 900 can receive sonar signals from a sonar system through the network interface 944.
In certain implementations, the central processing unit 930, GPU 931, video adapter 932, network interface 944, and system memory 926, hard disc 950, monitor 934, and screen 905 can be integrated into a console.
