User Interface Elements for Compact Menu

Description

TECHNICAL FIELD

This disclosure relates to a system, a computer-implemented method and a computer program for generating user interface (UI) elements.

BACKGROUND

There are many known techniques for displaying information to a user. In one example, “cascading” menus of information can be used. An example of a cascading menu is illustrated in granted European patent 0 717 344.

In a cascading menu, a number of different selectable options are displayed to a user, and the user can provide an input in order to select one of the options. Once an option has been selected, another set of selectable options are displayed, each of which can be selected by the user in order to display a further set of options, and so on.

A conventional cascading menu may be appropriate for use when there is a limited number of options for the user to choose from or when a large amount of display area is available. However, where there is a large number of options available for selection, and if each option has a large number of sub-options, conventional cascading menus may be inappropriate. In these scenarios, display area can be consumed by the cascading of different options. In addition, it may be difficult for the user to select options, particularly if the size of the user interface elements have been reduced in order to conserve display area.

These conventional cascading menus may be unsuitable when a small display area is available, which is particularly relevant in modern environments where users tend to consume information using smaller screens, such as those used in smart-phones. In these devices, users may find it difficult to manipulate the touch-screen in order to quickly and easily select the desired options in a particular order.

Thus, there exists a need for a technique that uses display resources more efficiently so that a user can visualise large amounts of information and navigate through selectable options for interrogating the information.

DETAILED DESCRIPTION

Described herein are processing systems and methods that use a first set of interactive user interface (UI) elements displayed in a first arcuate shape, and a second set UI elements displayed in response a user selecting a UI from the first set. This allows the elements to be displayed in a more compact arrangement which makes more efficient use of display resources.

The user can make a selection more easily using the arcuate set of UI elements. This is particularly advantageous when a touch-screen with a small display area is used. For instance, in a situation where the user holds their device with one hand, it is possible for the user to make a selection with a slight rotation of their thumb around the arcuate shape in order make a selection. This is a simpler movement than would otherwise be required if a conventional cascading menu were used.

FIG. 1 illustrates the general architecture of a system 2 for generating UI elements, such that a compact menu can be displayed to a user. The system may comprise any number of computing devices, such as a desktop computer 1, a “tablet” computer 3, and a smartphone 5. The computing devices 1, 3 and 5 are arranged to communicate with one another and with a server 9, via a communications network 7.

The communications network 7, in this example, is the Internet 7. However, it will be appreciated that any suitable form of communications network could be used.

The computing devices 1, 3, 5 are web-enabled by including an embedded browser or “app” or similar. In addition, each device 1, 3, 5 comprises a display, a user interface device, a processor and memory. The server 9 comprises a memory and a processor.

The devices 1, 3, 5 and the server 9 can be arranged to communicate data between one another via any suitable communications protocol or connection. For instance, the devices 1, 3, 5 and server 9 may communicate with one another via a wired and/or a wireless connection.

In the following example, each of the devices 1, 3, 5 may wish to view data stored at the server 9, such as the data illustrated in FIG. 2. This example data set comprises a large number of “classes” 13 denoted by the labels “class X−1”, “class X” and “class X+1”. The term class is used herein to refer to a particular entity, type or category of data. For instance, each class might signify a person, a particular location, such as country or town, or an institution, such as a company or a school etc.

As illustrated in FIG. 2, the data is arranged in a hierarchical structure comprising a number of different “layers” 15. Although four layers 15 are shown in FIG. 2, it will be appreciated that any number of layers 15 could be comprised in the data structure.

In each layer of data there are additional entities or “characteristics” 17 that stem from the class and/or a characteristic in the previous layer. For example, “class X” 13 may be a country such as the United Kingdom (UK), and in the first layer 15 the characteristics 17 associated with the UK may be “Gross Domestic Product”, “Population”, “Land Mass”, “Constituent Parts” and “Spoken Languages”. Each one of these characteristics 17 may be associated with a particular number. For instance, the “Population” characteristic 17 may be associated with the current population of the UK.

In the next layer 15 (“Layer 2”) there are additional characteristics 17, each associated with a characteristic 17 in the previous layer 15 (“Layer 1”). To use the “Population” characteristic 17 as an example, the characteristics 17 in Layer 2 associated with “Population” may indicate the population of each constituent part of the UK, such as Scotland, England, Wales and Northern Ireland. Each one of these characteristics may be associated with a data item comprising a number indicating the population of each one of these constituent parts.

As illustrated in the FIG. 2, at each layer 15 moving down the hierarchy more detailed information is contained within the characteristics 17 of that layer. Thus, by moving down the hierarchy it is possible focus in on more specific data. On the other hand, moving up the hierarchy allows a broader overview of the class to be obtained.

Using conventional techniques it is a challenge to present data, such as the data described with reference to FIG. 2, to a user in an effective manner. In addition, conventional techniques are not capable of allowing the user to navigate through the various layer 15 in a simple and effective manner.

A computer-implemented method for operating the system shown in FIG. 1 will now be described using the data illustrated in FIG. 2 as an example. This method, which is described below, may be carried out on at least one of the devices 1, 3, 5. The method may also use at least one server 9 and the communications network 7.

FIG. 3 shows a flow chart illustrating, at an overview level, a method of generating UI elements. These elements can be displayed to a user in the form of a compact menu that allows the user to navigate through data, such as the data described with reference to FIG. 2. The arrangement of the compact menu allows display screen resources to be used efficiently and allows a user to interact with the menu in a simple manner. FIG. 4 illustrates, in schematic form, some of the features of the system 2.

In step 20, input data is received at a communication interface 51 in the system 2. The input data may be the data described with reference to FIG. 2. However, it will be appreciated that any other suitable form of data could be used.

In step 22, an element generation module 53 identifies the classes in the data, such as “class X−1”, “class X” and “class X+1”, which in this example indicate different countries. Then, in step 24, the element generation module 53 generates a user interface element for each class. These UI elements are displayed by a display module 55, via a display screen such as a touch screen display 59.

An example of the UI elements 60 that are generated and displayed for each class is illustrated in FIG. 5. In this case, each one of the UI elements 60 is circular and is associated with one of the classes in the input data. For instance, UI element 61 is associated with “class X−1”, UI element 62 is associated with “class X” and UI element 63 is associated with “class X+1”. Text indicative of the class may be displayed inside each UI element in order to indicate which UI element is associated with which class. The size of each UI element may be indicative of the relative size/weighting score of the class associated with each element, in comparison to other elements. The size/weighting score for each class may be calculated based on the sum of the characteristics associated with a particular class, and a particular weighing may be assigned to each characteristic in order to produce a weighted score. Each UI element can be selected by the user so that more detailed information can be displayed in connection with the class associated with the UI element selected by the user.

In step 26, the user selects a class. In this example, the user selects UI element 62, which is associated with “class X”, by using the touch screen 59 to initiate a touch-gesture in the location of the UI element 62. Then, in step 28 a variable “N” is set to equal 1.

In step 30, the element generation module 53 generates a compact menu. An example of the compact menu 70 is illustrated in FIG. 6A. This menu 70 can be used to navigate through the various characteristics associated with the selected class. This compact menu 70 is displayed using the display module 55, via the display screen 59. In step 30, N is equal to 1 and therefore a first set of UI elements 72 is displayed.

Referring to FIG. 6A, the compact menu 70 comprises a first set of interactive UI elements 72. Each one of the UI elements 72 in the first set is associated with a characteristic of a first set of characteristics. Each one of these characteristics may have a value, text or character string associated with it, and this information is displayed in proximity to each respect UI element 72. In FIG. 6A, the name of the characteristic would appear where the label “Characteristic 1.n” appears, and the value, text or character string would appear where the label “X 1.n” appears. In addition, the first set of characteristics is associated with the class selected by the user.

To carry forward the example used above, the user selects the UI element associated with the “United Kingdom” class. In response, the display module 55 displays a compact menu with a set of five UI elements 72. Each one of these elements is associated with one of the “Gross Domestic Product”, “Population”, “Land Mass”, “Constituent Parts” or “Spoken Languages” characteristics respectively. Labels indicative of these characteristics may be displayed alongside their respective UI elements along with the value associated with the characteristic.

As illustrated in FIG. 6A, the interactive elements 72 of the first set are displayed in an arcuate shape, which in this case is a circular shape. The arcuate shape of the UI elements allows the compact menu 70 to use display resources efficiently, since the UI elements can be arranged to occupy a smaller area of the display screen. In addition, the arcuate shape allows the user to select the UI elements more easily, since the user can simply rotate their thumb to select a different element. This is more convenient for the user than engaging in a gesture which may require the use of an additional hand or the use of a scrolling gesture.

The first set of interactive elements 72 are spaced along the first arcuate shape. In this case, the elements 72 are positioned adjacent one another. However, the elements 72 could be positioned with a gap between adjacent elements 72 in order to help to avoid the user from accidently selecting an unintended element. In this example, the first set of interface elements 72 are spaced along the first arcuate shape in a single row of elements.

The UI elements 72 of the first set are arranged in a partial ring, where the ring is unclosed and comprises a gap. In this example, the gap is at least one quarter of the length of the circumference of the ring. This gap provides a space where no UI element is present. In this way, the user is able to position their thumb over this gap when operating the menu in order to help to avoid accidently engaging with a UI element unintentionally.

In addition, the compact menu 70 comprises a labelling element 71, which is indicative of the class associated with the characteristics of the first set of UI elements 72. The compact menu also has a layer element 74, which is indicative of the layer of the characteristics associated with the first set of UI elements 72. To use the example above, the “Layer 1” element would indicate “General Country Characteristics” and the labelling element 71 would indicate “United Kingdom”.

In step 32, it is determined whether the variable “N” is greater than 1. In this case, since “N” was set to be equal to 1 in step 28, the method proceeds to step 34 in which it is determined that no “breadcrumb” element is to be displayed. The purpose of the breadcrumb element will be described in greater detail later.

In step 36, a receiver module 57 receives a user input. Referring to FIG. 6B, the user input is received in respect of a first element 72′ in the first set. In this example, the user input is provided by the user initiating a touch-gesture via the touch screen 59. The location of this touch gesture is illustrated in FIG. 6B via the cursor 73 as being in proximity to the first UI element 72′. In this example, the first UI element 72′ is associated with the “Population” characteristic. Thus, the user's interaction with this UI element 72′ indicates that the user desires to determine more detailed information regarding the population of the United Kingdom.

Although a touch-screen display 59 is used in this example, it will be appreciated that any suitable form of user interface device could be used to receive a user input. For instance, the user input may be received via a “mouse” or a keyboard etc.

Referring to FIG. 6C, in step 38, and in response to the user input, the variable “N” is incremented by 1, such that “N” is equal to 2. Then, the method proceeds to repeat step 30 where it is determined that the Nth (or in this case the second) set of interactive UI elements 76 is to be generated and displayed. Each one of the UI elements 76 in the second set is associated with a second set of characteristics. In addition, each one of the UI elements 76 in the second set is associated with the characteristic of the first element 72′ that was selected by the user in step 36 and illustrated in FIG. 6B. In this example, the selected characteristic was the “Population” characteristic. Therefore, each of the UI elements 76 in the second set provides further information regarding the “Population” characteristic.

Also, in step 38 an additional layer element 74 is displayed, which indicates that the user is viewing UI elements 76 of the second layer (or “Layer 2”) in the data. In this example, the Layer 2 element indicates “Population”, whilst the labelling element 71 continues to indicate “United Kingdom”. In this way, it is possible for the user to determine that the UI elements 76 of the second set provide further information about the population of the United Kingdom.

FIG. 6C illustrates the compact menu 70 that is displayed and generated by the element generation module 53 and the display module 55. The UI elements 76 of the second set are arranged in a similar arcuate shape to that described with reference to FIGS. 6A and 6B. However, there are three UI elements 76 in the second set, whereas there were five in the first set of UI elements 72. However, this number of UI elements is provided as an example only, and it will be appreciated that any number of UI elements could be generated and displayed in the first or second sets, dependent on the number of relevant characteristics to be displayed to the user.

In step 32, the method determines whether “N” is greater than 1. Referring to FIG. 6C, since “N” is equal to 2 the method proceeds to step 40, in which a breadcrumb element 75 is generated and displayed. The breadcrumb element 75 is used so that the user can reverse to the previous set of UI elements. When the compact menu 70 displays the first set of UI elements 72, it is not required to display the breadcrumb element 75 because the UI elements associated with the “top” layer of characteristics is displayed. Thus, there is no previous set of UI elements which can be reverted to.

FIG. 6C illustrates the breadcrumb element 75 that is displayed and generated in step 40. The breadcrumb element 75 has a similar arcuate shape to the first arcuate shape of the first set of UI elements 72. However, the breadcrumb element 75 has a shorter width that than the first arcuate shape, and is positioned within the second set of UI elements 76. Thus, the breadcrumb element 75 forms a third arcuate shape within an interior circumference of the second arcuate shape.

After step 40 has been executed, if the user selects the breadcrumb element 75, the method may proceed to step 42. Alternatively, if the user selects a UI element 76 in the second set of elements, the method proceeds to repeat step 36.

In step 42, the user can select the breadcrumb element 75 in order to revert the display back to the previous set of UI elements. The user selecting the breadcrumb element 75 is illustrated in FIG. 6D by the position of the cursor 73.

If the user selects the breadcrumb element 75, “N” is reduced by 1 in step 44, and the method proceeds back to step 30. In this step, the first set of UI elements 72 are displayed again to user, as illustrated in FIG. 6A. In addition, the second set of UI elements 76 are hidden in response to the user selecting the breadcrumb element.

Alternatively, from step 40 the method proceeds to step 36 if the user selects a UI element 76′ from the second set of elements 76. This is illustrated in FIG. 6E, where the cursor 73 indicates the location of a touch-gesture made by the user in respect of the UI element 76′ from the second set of elements. In response to the user selection, steps 38, 30, 32 and 40 are repeated in a similar manner to that described above.

The repetition of these steps cause the menu 70 illustrated in FIG. 6F to be displayed. In these steps, the element generator module 53 and the display module 55 are arranged to generate and display a third set of interactive UI elements 77 each associated with a third set of the characteristics. In addition, the UI elements 77 in the third set are associated with the characteristic of the UI element 76′ that was selected in step 36. As shown in FIG. 6F, the breadcrumb element 75 is displayed. However, in this instance, selection of the breadcrumb element 75 will revert the display back to the menu 70 comprising the second set of elements 76, as illustrated in FIG. 6C.

In a similar manner to that described above, step 36 onwards can be executed again in connection with the UI elements 77 of the third set. Referring to FIG. 6G, the user selects a UI element 77′ from the third set, which causes a fourth set of UI elements 79 to be displayed, which is shown in FIG. 6H. The breadcrumb element 75 in this display be used to revert back to the display illustrated in FIG. 6F. In addition, the user can initiate a touch-gesture in the location of a layer element 74 in order to revert back to the set of UI elements corresponding with the layer element 74 selected. For instance, the user can select the “Layer 1” element to revert back to the first set of UI elements 72 illustrated in FIG. 6A. In another example, the user can select the “Layer 2” element to revere back to the second set of UI elements 76 illustrated in FIG. 6C. This avoids the need for the user to select the breadcrumb element 75 multiple times in order to revert back more than one step.

The display screen 59 in the system 2 may be comprised within a desktop computer 1, a smartphone 5 or a tablet 3. The display screen may have a diagonal length of less than 30.5 cm (12 inches) or less than 12.3cm (6 inches).

The modules of the system 2 described above with reference to FIGS. 1 and 4, may be distributed throughout the system at any number of different devices. For instance, the smartphone 5, tablet 3 or desktop computer 1 may comprise the communication interface 51, the element generation module 53, the display module 55 and the receiver module 57.

In another example, the server 9 comprises the communication interface 51 and the element generation module 53; and a client-side device 1, 3, 5 comprises the display module 55 and the receiver module 57. In this way it is possible to off-load some of the more computationally intensive actions to the server 9, rather than the client-side device 1, 3, 5.
