Definitions

  • the present invention relates to a display generating device and has particular but not exclusive application to multimedia network terminals.
  • GUIs graphical user interfaces
  • Such devices include, for example, personal computers (PC), televisions and mobile telephones.
  • the user may interact with the device via the GUI using a user interface, for instance a touch sensitive pad, a keyboard, a mouse or a joystick.
  • a user interface for instance a touch sensitive pad, a keyboard, a mouse or a joystick.
  • Many factors determine the most appropriate choice of user interface for a device, such as ease of use and speed of operation and the environment in which the device is used.
  • the use of a mouse is suited to the selection of icons when using a desk-top personal computer. However, it is not so useful for a digital television set. For this, a remote control unit having several keys is more convenient.
  • Digital television systems provide a variety of new services as compared with analogue television. They allow the user to transmit and receive signals via a set-top box and to interact with service providers.
  • the user may now access the Internet in a similar way that is already available on a PC. For example, a user may navigate web pages by selecting hypertext links.
  • the process of selecting a particular link involves moving a focus between links and activating selection. In a PC-based system, this process is realised by positioning a mouse pointer over the Unk and pressing the mouse button. To indicate that the focus has moved to the Unk, the shape of the mouse pointer changes or the Unk is highUghted, for instance, by changing colour.
  • the set-top bo /television system is controlled using a remote control unit, which is similar to that used in analogue television systems.
  • the remote control is usually provided with a set of arrow keys —up, down, right, left— allowing orthogonal movement about a menu.
  • Such a remote control unit provides a satisfactory means for selecting elements of the menu if the menu is arranged as a rectangular array along co-ordinates defined by the keys on the remote control. Elements in a column are selected by the use of up and down arrow keys, while elements along a row may be selected by use of right and left arrow keys. Thus, movement from one element to another is straightforward and intuitive.
  • Hypertext Unks may be represented by text or images which are not uniformly located on the page.
  • GB-A- 2357945 describes a device which seeks to overcome this problem by generating an ordered array of navigable nodes such that each link is represented by at least one node. The user can intuitively and reversibly navigate around the array to reach and select Unks.
  • Unks may not be completely irregular. Links may be ordered in one direction but not another. For example, it is common to have a block of text in which is embedded several hypertext links. In this case horizontal movement between Unks using left and right arrow keys is straightforward since the text is arranged in rows. However, the Unks may not be vertically aUgned. If a Unk in one row is in focus and there are two Unks in the row below, vertical movement using the down arrow key is more compUcated since there are two Unks to chose from. Nevertheless, it is likely that the user wiU want to select the Unk which Ues obviously or intuitively below the Unk in focus, even though it may not be the closer of the two Unks.
  • the present invention seeks to solve this problem.
  • a generating device configured to generate signals for a graphical display in which a focus can be navigated between spaced, functional display regions such that they are individually selected when the focus is moved thereto, comprising means for determining first and second weighted distances between a first functional display region in focus and second and third functional display regions respectively and means for selecting one of said second or third functional display regions in dependence upon said first and second weighted distances.
  • the means for determining said first and second weighted distances may be configured to receive respective coordinate information for said first, second and third functional display regions.
  • the means for determining said first and second weighted distances may be arranged to execute a predetermined mathematical method on said coordinates.
  • the predetermined mathematical method may include a mathematical function, such as eUiptic or lemniscate function.
  • the device may be included in a multimedia network terminal, such as an internet enabled set-top box.
  • a method in a generating device configured to generate signals for a graphical display in which a focus can be navigated between spaced, functional display regions such that they are individually selected when the focus is moved thereto, of operating said device, the method comprising determining first and second weighted distances between a first functional display region in focus and second and third functional display regions respectively and selecting one of said second or third functional display regions in dependence upon said first and second weighted distances.
  • a method of navigating a focus between spaced, functional display regions on a display device comprising determining first and second weighted distances between a first functional display region in focus and second and third functional display regions respectively and selecting one of said second or third functional display regions in dependence upon said first and second weighted distances.
  • a computer program comprising computer code to make a computer configured to generate signals for a graphical display in which a focus can be navigated between spaced, functional display regions such that they are individually selected when the focus is moved thereto execute procedure to determine first and second weighted distances between a first functional display region in focus and second and third functional display regions respectively and to select one of said second or third functional display regions in dependence upon said first and second weighted distances.

  • an embodiment of display generating device is a digital set-top box 1 which is connected to a display device in the form of a conventional television set 2.
  • the set-top box 1 is controlled using a remote control unit 3 having up, down, right and left keys 4a, 4b, 4c, 4d and a select button 4e.
  • up, down, right and left directions correspond to movement as seen on the television set 4.
  • the set-top box 1 comprises one or several input ports (not shown) including a port for a satelUte antenna dish, a port for a terrestrial antenna, a port for a cable Unk and a port for a broadband internet connection and an output port (not shown) for connection to the television set.
  • the set-top box 1 further comprises a microprocessor, memory, front-end tuner for filtering the signal, a video chip for rendering an image on the television set 2 and a user interface (not shown).
  • the set-top box 1 may be used to receive and decode digital television channels and transmit user information via a return channel. These channels are transmitted and received through a cable Unk, although Unks provided by satellite or terrestrial broadcast may also be used.
  • the set-top box 1 provides Internet services to the user, thus enabhng the user to read e-mail and "surf the web". To access the web, the set-top box 1 loads and runs web browser software.
  • the web browser software is used navigate a web page 5 which comprises text 6 including first, second, third, fourth, fifth and sixth hypertext Unks 7 token 7 2 , 7 3 , 7 4 , 7 5 , 7 6 .
  • the text 6 relates to the results of a search for the term "http".
  • the first hypertext Unk 7a is a Unk back to a previous page.
  • the second Unk 7 2 is a box for entering a new search term.
  • the third and fourth links 7 3 , 7 4 are Unks to related web pages.
  • the fifth Unk 7 5 is a Unk to a page relating to a different topic.
  • the sixth Unk 7 6 is a Unk to an e-mail appUcation.
  • a focus 8 is set at the third Unk 7 3 and is highUghted in a different colour from the other Unks 7 2 , 7 4 , 7 5 , 7 6 .
  • Rows may be defined for example by defining a horizontal band and determining whether Unks contained therein constitute a one-dimensional array. In this case, a user can navigate between these Unks using right and left arrow keys 4c, 4d. Thus, to move the focus 8 from the third Unk 7 3 to the second Unk 7 2 , the user presses the left arrow key 4d on the remote control unit 3. Similarly, to move the focus 8 from the third Unk 7 3 to the fourth Unk 7 4 , the user presses the right arrow key 4c.
  • the third, fourth, fifth and sixth Unks 7 3 , 7 4 , 7 5 , 7 6 do not Ue neatly in a column. Furthermore, the user is Ukely to want to move the focus 8 from the third Unk 7 3 to the sixth Unk 7 6 in preference to either of the fourth or fifth Unks 7 4 , 7 5 even though those Unks are closer.
  • the web browser software calculates weighted distances between the third focus 7 3 and each of the fourth, fifth and sixth Unks 7 4 , 7 5 , 7 6 respectively, weighted according their horizontal displacement from the third Unk 7 3 , and determines which of them is closest.
  • the web browser software initiaUses a current Unk counter i, sets a selected link variable s to one and a focus-to-selected Unk distance variable r s 2 to a predetermined value, for example to the square of the diagonal distance p across the page 5 (step SI).
  • the Unks 7 are numbered according to their position on the page 5, starting from the top left and finishing at the bottom right of the page 5.
  • step S3 determines whether the current Unk 7 ; Ues below the third Unk 7 3 (step S4). In this - example, this is done by checking whether an upper edge 9 ; of the Unk 7 ; is below a lower edge 10 3 of the third Unk 7 3 which is in focus. It will be appreciated that other criteria may be used such as minimum vertical offsets between a y-midpoint 11; between upper and lower edges 9 i5 10; of the current Unk 7 ; and a y-midpoint 11 3 between upper and lower edges 9 3 , 10 3 of the third Unk 7 3 .
  • step S3 the browser moves onto the next Unk 7; +1 (step S3).
  • the fourth, fifth and sixth Unks 7 4 , 7 5 , 7 6 Ue below the third Unk 7 3 .
  • the browser then measures horizontal and vertical displacements ⁇ x ; , ⁇ y ; from the third Unk 7 3 to the current Unk 7.-.
  • step S7 If the current Unk 7- Ues to right of the third Unk 7 3 such that the leftmost edge 13 ; of the current Unk 7.- lies to the right of the x-midpoint 12 3 of the third Unk 7 3 (step S7), then the leftmost edge 13 ; is used to calculate the horizontal displacement ⁇ ; (step S8).

  • the vertical displacement ⁇ y is measured from the y-midpoint 11 3 of the third Unk 7 3 to the y-midpoint 11 ; of the current Unk 7 ; (step S 0).
  • the browser calculates a weighted distance r ; 2 between the current Unk 7- and the third Unk 7 3 (step Sll). This is done using an elUptic function:
  • k is a constant.
  • a value of k may be fixed by the software or defined by the user. Alternatively, it may be dynamicaUy determined according to, for example the duration that the down arrow key 4b is pressed. The significance of the value of k wih be described later.
  • the browser checks whether the weighted distance r ; 2 between the current Unk 7 ; is less than the focus-to-selected Unk distance variable r s 2 (step SI 2). If it is, then the weighted distance r ; 2 is stored in the focus-to-selected Unk distance variable r s 2 and the current Unk 7; is flagged as the selected Unk 7 S (step SI 3), otherwise no values are stored and the browser simply moves onto the next Unk 7 i+1 (step S3). In this example, squared values of distance are computed and compared. It will be appreciated that proper values of distance may be computed although this will increase computing time.
  • the browser iterates through all the links (step SI 4). Once it has done this, the focus 8 moves to the selected Unk (step SI 5).

Abstract

L'invention concerne un système de télévision numérique comportant un boîtier de décodage contrôlé par une unité de commande à distance pour accéder à Internet. Des touches de flèches sur l'unité de commande permettent de naviguer autour de liens hypertext positionnés de manière irrégulière sur une page web. Si l'on presse une touche avec une flèche vers le bas, le logiciel d'exploration détermine les distances pondérées entre un lien sur lequel on est focalisé et des liens au-dessous de ce dernier à l'aide d'une fonction elliptique. Les distances sont pondérées pour favoriser un lien plus près colinéaire dans le sens vertical même si d'autres liens sont plus proches.
