`
`Method and an arrangement for scrollable cross point navigation in a user
`interface
`
`Technical field
`
`5
`
`The present invention pertains to a method and an arrangement for scrollable
`cross point navigation in a user interface in order to select a feature by combining two
`object fields each belonging to each one bar.
`
`Prior art
`
`Traditional selection of services or adjustment of, for example, TV, set-top box,
`domestic appliances settings, and other like device settings has the disadvantage of
`covering an entire display area and requiring a lot of key-presses. This constitutes a
`major problem for most users of such equipment, but especially for disabled persons
`and those who are unfamiliar with or unsecured in setting electronic devices, or in
`reading manuals.
`
`Another problem with today device settings, relating to manuals, is the
`language used in the manuals. It is often written in a technical logic language easy to
`understand for a technician, but perhaps hard to grasp for others.
`
`Furthermore, some devices sold do not have a manual teaching settings in a
`language of a buyer of the same, or in a language of a non-native purchaser.
`Still further, it is a well known fact that remote control devices, such as for the setting
`of TV -sets, are crowded with keys, and that the design of key pads is different between
`different manufactures of like devices.
`
`Hence, it is believed that an easy interface for setting of appliances is needed to
`overcome drawbacks and problems related to today appliance control interfaces.
`
`Summary of the described invention
`
`An aspect of the present invention is to provide a method and an arrangement
`that brings a solution to above problems and others related to the setting of appliances
`controlled by remote control devices such as wireless and pointing devices or even
`voice control devices. Suitable appliances to be controlled are amongst others, e.g.
`television sets, satellite receivers, set-top boxes, computers, household equipment,
`telephones, mobile phones, personal digital assistants, CD-players, stereo equipment
`etc, especially appliances provided with user interfaces such as display screens for
`interaction with remote control and other key pad devices.

`
`In order to present a solution to said problems the present invention sets forth a
`method for scrollable cross point navigation on a user interface in order to select a
`feature by combining two object fields. Two bars are provided, where at least one of
`them is scrollable, each of them having at least one object field which overlap and
`combine each other when scrolled to a visible focus area in the user interface at the
`cross point of the bars. Thus, it is accomplished that object fields in the focus area
`select a feature connected to the combination of fields when chosen by a confirmation
`action.
`
`5
`
`In one embodiment of the invention, one feature function is defined as a sub
`cross point navigation method, i.e., another level of scrollable cross point navigation.
`
`10
`
`Another embodiment of the invention provides object fields that are visible, but
`where some may be invisible object fields in the bars, which are connected in a cyclic
`manner to each other.
`
`Scrolling is accomplished by feeding or "zapping" up and down or left or right
`in order to move objects to the focus.
`
`15
`
`In still another embodiment an information field is displayed in the user
`interface comprising text describing the feature connected to the focus area.
`
`In yet another embodiment the focus area is marked.
`Yet another embodiment comprises that the bars are small thus making an
`image display on the screen possible even when all bars are visible. Also, the bars
`may be visibly transparent.
`
`20
`
`Preferably, in one embodiment, features in bar object fields are displayed in
`sequence in object fields in one of the bars when focus is confirmed.
`
`25
`
`An embodiment comprises that confirmation and scroll action is accomplished
`by actuating one of five function commands left, right, up, down, and OK or like
`confirmation.
`
`In a further embodiment the focus area enables to show (bring about) all
`functions for any apparatus guided by cross point navigation through the function
`commands.
`

`
`Furthermore, the present invention sets forth an arrangement for scrolled cross
`point navigation on a user interface in order to select a feature by combining two
`object fields, whereby it comprises:
`two bars, where at least one of them is scrollable, each of them having at least
`one object field which overlap and combine each other when scrolled to a visible focus
`area in the user interface at the cross point of the bars; and

`
`whereby object field means are used to select a feature connected to the
`combination of object fields in the focus area, which is chosen by confirmation and
`scrolling means.
`
`One embodiment of the invention comprises that said object field means is an
`interaction interpreter between said input device and a graphic generator which is
`connected to a graphic library for creating the bars and by them comprised function
`features or finite features.
`
`Another embodiment comprises that said object field means further include a
`content database connected to said graphic generator and a user interface objects
`database connected to said library and to said generator.

`
`For a more complete understanding of the present invention and for further
`aspects and advantages thereof, reference may now be had to the following description
`taken in conjunction with the accompanying drawings, in which:
`Fig. 1 is a schematic block diagram illustrating one embodiment of means used
`to accomplish an anangement in accordance with the present invention; and
`Fig. 2a and 2b schematically illustrating a user interface in accordance with the
`present invention.
`
`Detailed description of prefened embodiments
`
`The present invention relates to a method and an anangement for scrollable
`cross point navigation on a user interface in order to select a feature comprised in a
`combination of two object fields. A cross point navigation ensures a creation of a
`system that allows a user of appliances such as digital TV set-top boxes to navigate
`and select different types of services in an easy way without disturbing the actual
`viewing experience of the user. It is also designed to assist the user in the forthcoming
`expansion of both TV-channels and digital TV Services. There is a clear need for a
`system allowing cross point navigation as described.
`
`Henceforth describing embodiments of the present invention by way of the
`setting control of a digital TV set-top box, the present invention is not restricted to
`such appliances. All kind of appliances with key pads, wireless or other remote control
`
`Page 5 of 23

`
`functions can make use of the present invention, especially if they are equipped with a
`user interface such as a screen or display area and other interfaces where the control of
`an appliances is visually prompted. A Cross point navigation system according to the
`present invention could be used in many other contexts where the display area is
`important to the user. The system could be displayed in infmite ways, allowing it to be
`adaptable for most cases of operation. Expansion possibilities of the system are
`unlimited which allows users to understand and interact with the system in very
`complex environments and still feel confident that they are in fully control of the
`interaction.
`
`Cross point navigation is meant to allow a user of an appliance as much control
`as possible. Navigation principles according to the present invention allow the user to
`navigate to e.g. a TV channel or Service, herein described as features, desired with
`only four navigation keys on a remote control device. No confirmation is required until
`the requested object is in focus. This is accomplished by pressing, for example, an Ok
`button or the like on the remote control.
`
`Also, cross point has the benefit of being easily adaptable by users. Interaction
`is self-explanatory and once a user has made a first selection it is obvious how to
`proceed with other system possibilities of it. Every step of the interaction provides an
`immediate feedback.
`
`Illustrated in Fig. 1 is a schematic block diagram showing means used to
`accomplish an arrangement 10 in accordance with the present invention which in one
`embodiment of the invention comprises an UI objects database 12, a Graphic library
`14, a Graphic generator 16, an Externally supplied data means 18, a Content database
`20, an Interaction interpreter 22, an Input device 24, and a User Interface 26.
`
`The Input device 24 depicted in Fig. 1 is a means for controlling a User
`Interface 26. It could amongst others be a remote control for a set-top box, a keyboard
`for a PC or a control panel for a microwave oven. When a user wants to change the
`setting of the Interface 26 it is manipulated to transmit a signal to an Interaction
`interpreter 22.
`
`An Interaction interpreter interprets signals from the Input device 24 and sends
`a corresponding action to a Graphic generator 16. The Interaction interpreter 22
`transforms commands from the Input device 24 to actions provided by the Graphic
`generator 16.
`
`Furthermore a Content database 20 is provided that contains information which
`can be presented in the User Interface 26. Samples of such information could be e.g.
`names of object fields (shown in Fig. 2a and 2b) containing function objects or finite

`
`objects and help-texts that should be presented to users in a given context. A function
`object is mostly a more complex setting not directly leading to a setting of a feature for
`an appliance and a finite object. mostly leads to a direct setting of a feature for an
`appliance. All material in the Content database 20 can be altered or edited by a content
`provider.
`
`5
`
`Externally supplied data 18 is a symbolic representation of any content that is
`inserted into the Content database 20 from any source.
`
`Still further, the UI objects 12 database contains types of graphical objects that
`can be presented in the User Interface 26. Said database supplies a Graphic library 14
`10 with generic representations of said types. Hence, the Graphic library 14 contains
`functions to manipulate the UI objects in the Interface 26. It supplies the Graphic
`generator 16 with specific instances from the UI objects 12 database.
`
`15
`
`The Graphic generator 16 handles the presentation of the User Interface 26 as
`well as manipulation accomplished by a user. Thereby it performs actions signaled by
`the Interaction interpreter 22 through collecting content from the Content database 20
`and by merging the content with the Graphic library 14 and delivering presentation of
`a desired action to the User Interface 26. The User Interface 26 presents feedback of
`any action performed by users of the Interface 26.
`
`Fig. 2a and 2b are schematically illustrating a user interface 26 in accordance
`20 with the present invention.
`
`A user of an Interface 26 through the Input device 24 may, for example, select a
`combination of an object field comprising objects such as function features defining a
`setting and a finite object field comprising fmite features, by feeding the object field
`comprising functions or the finite object field comprising finite features into a focus-
`area 30 with the User Interface 26. If a field with function features is located in a
`vertical bar, object fields A - G in Fig. 2a, is in focus 30 its function features I fmite
`features are displayed in the horizontal bar 34. Likewise if a function feature in the
`horizontal bar 34, object fields FO - F5 in Fig. 2a, is in focus 30, its fmite features I
`function features are displayed in the vertical bar 32. Whenever an object field
`comprising objects such as function features is fed into the focus area 30 its content
`overwrites the content of the opposite (other) bar 32, 34.
`
`Such interaction allows a user to navigate to a desired combination of object
`fields A-G and e.g. FO-F5 (shown in Fig. 1), AO-A5 (not shown), DO-D5 (not shown)
`etc without the manipulation of other keys than Right, Left, Up and Down on a
`keyboard or pad. A user then selects combined features in focus 30 by using a
`manipulation key or button such as Ok, confirm, select etc.

`
`According to above a user can interact with the cross point method and/or
`anangement according to the present invention in a zapping mode as comparing to the
`prior art of moving in a channel list.
`
`Further, in one embodiment of the invention only the Focus Area 30 and an
`information field 36, not entire bars 32, 34 are displayed in the user interface 26. Also,
`if entire bars 32, 34 are shown they can be transparent, thus allowing a more detailed
`view of a background picture e.g. TV picture 36, graphics etc. Bars 32, 34 do not
`necessarily need to be elongated in a straight line, the important feature is that the so
`called bars 32, 34 make up a focus area 30 when crossing each other. Moreover, the
`focus area 30 may be marked, highlighted, shadowed etc, making it easier to observe
`for users.
`
`Now refening to Fig. 2b illustrating an example of one possible change in the
`bars 32, 34, A-G and FO-F5 in Fig. 2a, when object fields FO and F2 are combined in
`focus 30 making up object field F2:0 in focus 30. The combination was accomplished
`by feeding the bar 34 object field F2 to the focus area 30, thus overwriting object field
`FO in bar 32, which combination makes up a vertical bar 32 with new object fields
`F2:0-F2:5. The feeding direction is indicated by index 2:0 in F2:0, i.e., horizontal bar
`34 fed to focus and F2 overlapping F:O.
`
`Now refening to Fig. 2a and 2b for an example of one possible embodiment of
`the present invention of setting a feature for a TV set equipped with a set-top box.
`Supposing that the vertical object field FO in Fig. 2a comprises or contains the finite
`feature of making up a personal TV program or channel list with channels listed from
`program places 1, 2, 3, 4 ... , and that the horizontal object field F2 contains the fmite
`feature of channel CNN™. Hence, by feeding the field F2 to FO with the key for left or
`right (circular bars) feeding with a key pad and thus overlapping field FO and confirm
`the setting by pressing a confirmation key it is accomplished that object fields A-FO in
`the vertical bar 32 are changed to comprise the object fields F2:0-F2:5 which contain a
`sequence of finite features defining a place in a personal channel list. By feeding F2: 1
`with the down or up key of the key pad 24 down to the focus area 3 0 and pressing the
`confirmation key, the channel CNN™ is placed at position 1 in the personal channel
`list.
`
`Moreover, giving an example of a function feature for a set-top box such a
`function could be to anange all news channels available in series at a special position
`in the channel list, for example, at program positions 10-15 in the personal channel
`list. This would be accomplished automatically when confirming the function feature
`with a confirmation key.

`
`Summarized, the invention may be described as follows:
`
`An electronic apparatus comprises a display on which a focus area is provided.
`The focus area is dedicated to display information which is necessary for a user to
`control the functions of the electronic apparatus.
`
`5
`
`The information to be shown to the user is divided into a number of individual
`items. These items are arranged in one or more levels. In any of the levels, the
`accompanying items are of similar detail.
`
`The items of a first level are very general. In a second level, the items are more
`detailed than in the first level, but are still some kind of general. In a third level, the
`items are even more detailed than in the second level. And so on.
`
`10
`
`Furthermore, the items are linked according to their contents. This means that
`an item of the first level is linked to one or more items of the second level. As well, an
`item of the second level is linked to one or more items of the third level. And so on.
`
`The items to be shown to the user may therefore be arranged as follows:
`
`15
`
`20
`
`25
`
`frrst level:
`second level:
`third level:
`fourth level:
`
`ABCDE ...
`AO A 1 A2 ... BO B 1 ... CO C 1 ... DO ... EO ...
`AO:O AO: 1 ... BO:O BO: 1 ... CO:O ... DO:O ...
`
`A, B, C, ... AO, AI, ... BO, ... AO:O, AO: 1, ... are items in the various levels,
`wherein
`and
`A, AO, AO: 1, ... are items which are linked together wherein the linkage is
`expressed by the use of the same character.
`
`With the above described structure, the items are arranged in a tree-like manner
`with any branch of the tree constituting a further level.
`
`The electronic apparatus is provided with an input device for changing the items
`shown in the focus area. With this input device, a user is able to change the items of
`the focus area as follows:
`
`On one hand, the user may change the items of the focus area within one and
`the same level. In this case, the user may change e.g. from A to B to C or from C 1 to
`CO or the like.
`
`30
`
`On the other hand, the user may change the items of the focus area from one
`level to another. In this case, the user may change e.g. from B to Bl or from D0:2 to
`DO to D or the like.
`
`For changing between the items of the various levels, there are at least two keys
`provided on the input device. The user may start to change between the items of the
`
`Page 9 of 23
`
`

`

`wo 00/65429
`
`8
`
`PCT/EP00/03637
`
`first level by pressing the first key. Then, for changing to the second level, the second
`key is pressed. For changing between the items of the second level, the user continues
`to press the second key. Then, for changing to the third level, the first key is used
`again. For changing between the items of the third level, the user continues to press the
`first key. And so on.
`
`As a result, the user may start with item A in the first level and may change
`within this level to all other items B, C, ... of this level by pressing the first key. Doing
`that, the user is able to read all items of this level and to select that item which is
`actually important for her/him. The selection is performed by bringing the important
`item into the focus area of the display.
`
`If the important item is within the focus area, the user may change to the second
`level by pressing the second key. Due to the fact that the user has selected a specific
`item of the first level before changing to the second level, the displayed items in the
`second level are all linked to this specific item of the first level. E.g., if the user has
`selected item C in the first level, one of the linked items CO, Cl, C2, ... of the second
`level is displayed after pressing the second key.
`
`Then, the user may change within this second level to all linked items CO, C 1,
`C2, ... of this second level by pressing the second key. The user may select that item
`which is important for her/him. This selection is performed by bringing the important
`item into the focus area of the display. If the important item is within the focus area,
`the user may change to the third level by pressing the first key again. And so on.
`
`This leads to the following example of subsequent changes of items in the focus area:

`
`With such a sequence of changes of items within the focus area, the user is able
`to select at the end that item which corresponds to the function of the electronic

`
`· apparatus required by the user. Then, the user presses e.g. a confirmation key on the
`input device so that the required function is performed by the electronic apparatus.
`
`5
`
`As long as there is a possibility to change from one level to a next lower level, a
`combination of two items of these two levels is displayed in the focus area. The first
`item of the combination belongs to that level in which the user is actually pe1forming
`changes. The first items, therefore, conespond to the items as described above. The
`second item of the combination of two items belongs to the next lower level. The two
`items to be displayed are linked together as described above.
`
`As examples, the following combinations of two items may be displayed in the
`focus area:
`
`10
`
`B+Bl
`F+FO
`D3+D3:5.
`
`With the described first key of the input device, the user may change the
`combination displayed in the focus area as follows:
`
`15
`
`B+Bl
`C+Cl
`D+Dl
`
`first key
`frrst key
`
`20
`
`This means that the first key enables the user to change between the items of the
`first level.
`
`With the described second key of the input device, the user may change the
`combination displayed in the focus area as follows:
`
`25
`
`B+Bl
`Bl+Bl:O
`Bl+Bl: 1
`Bl+B1:2
`
`second key
`second key
`second key
`
`This means that the user may change with the second key from the first level
`into the second level and may then change between items of the second level.
`
`30
`
`If the user then presses the first key again, the combination displayed in the
`focus area includes items of the second and the third level and the user may then
`continue to change between items of the third level by pressing the first key.
`Therefore, with any of the two keys, the user may change from a given level to
`the next lower level and may then change between the items of this lower level.

`
`In the lowest level, there is only one item of this level being displayed in the
`focus area, e.g. F2:0. This item may then be selected by the user with the confirmation
`key of the input device, as already described.
`
`5
`
`Furthermore, it is possible to display not only the focus area but also a number
`of additional areas on the display of the electronic apparatus. These additional areas
`may be displayed as a vertical bar and a horizontal bar as shown in figures 2a and 2b.
`
`10
`
`15
`
`In this case, one item is displayed in any of the additional areas and the items
`displayed in the additional areas of the vertical bar belong to the next higher or lower
`level as the items in the additional areas of the horizontal bar.
`
`If the user changes the item in the focus area, a shift of the vertical bar
`including the focus area or a shift of the horizontal bar including the focus area is
`performed. Such shifting or scrolling has the result that always that item is transferred
`into the focus area which was displayed as the neighboring item of the focus area in
`the vertical or horizontal bar prior to the shift.
`
`The shifting or scrolling may be performed in both directions of the vertical and
`horizontal bar. For that purpose, the input device may provide four keys, i.e. an up and
`a down key for the vertical bar and a left and a right key for the horizontal bar.
`
`With these four keys, it is also possible that the user also goes back to a higher
`level, e.g. from C4: 1 to C4.
`
`20
`
`With these four keys of the input device, the user may change the combination
`displayed in the focus area as follows:
`
`G+GO
`F+FO
`E+EO
`EO+EO:O
`El+El:O
`E2+E2:0
`El+El:O
`E+El
`F+Fl

`
`wherein in the last three lines of the above example, no combination of two
`items is displayed as F2:0, F2: 1, F2:2 relate to the lowest level. As a result of the
`example, the item F2:2 is selected by the user.
`
`It is thus believed that the operation and construction of the present invention
`5 will be apparent from the foregoing description. While the method and arrangement
`shown or described has been characterized as being preferred it will be obvious that
`various changes and modifications may be made therein without departing from the
`spirit and scope of the invention as defined in the attached claims.
