`s computer unit, which computer unit comprises a touch sensitive area, and which
`touch sensitive area is divided into a menu area and a display area.
`
`The computer unit is adapted to run several applications simultaneously
`and to present any active application on top of any other application on the display
`
`area.
`
`The present invention also relates to an enclosure for a handheld
`
`computer unit
`
`The present invention also relates to a computer readable medium. A
`
`computer program product with computer program code is stored within the

`
`Description of background art
`
`Mobile handheld computers are known in various embodiments. One kind
`
`of handheld computer is the personal digital assistant (PDA), which is getting more
`
`20 and more powerful.
`
`Another kind of handheld computer unit is the mobile pho11e, which also is
`
`getting more and more powerful. There are also examples of where the mobile
`
`phone and the PDA are merging into one unit
`
`A third kind of handheld computer is the laptop computer, which is getting
`
`25
`
`smaller and smaller, even competing in size with the PDA's.
`
`The need to manage more information has led the development towards
`
`new solutions regarding user interfaces and navigation. The PDA's and mobile
`
`phones are getting larger and larger in order to provide a user-friendly interface.
`
`Since the users have gotten used to small handheld units, it is hard to
`
`30 move towards larger units. This has led to foldable keyboards, different kinds if joy
`
`sticks and different kinds of touch sensitive displays and pads intended to help in
`
`providing a user interface that is suitable for small handheld compute units

`
`Summary of the present invention
`
`2
`
`Technical problems
`It is a problem to provide a user-friendly interface that is adapted to handle
`
`s
`
`large amount of information and different kinds of traditional computer-related
`
`applications on a small handheld computer unit.
`It is a problem to provide a user interface that is simple to use, even for
`
`inexperienced users of computers or handheld devices.
`
`It is a problem to provide a small handheld computer unit with an easily
`
`10
`
`accessible text input function.
`It is also a problem to provide a simple way to make the most commonly
`
`used functions for navigation and management available in the environment of a
`
`small handheld computer unit.
`
`1s Solution
`
`Taking these problems into consideration, and with the staring point from a
`
`user interface for a mobile handheld computer unit, which computer unit comprises
`
`a touch sensitive area, which touch sensitive area is divided into a menu area and
`
`a display area, which computer unit is adapted to run several applications'
`
`20
`
`simultaneously and to present an active application on top of any other application
`
`on the display area, the present invention teaches that the menu area is adapted
`
`to present a representation of a first, a second and a third predefined function,
`
`where the first function is a general application dependent function, the second
`
`function is a keyboard function, and the third function is a task and file manager.
`
`25 The present invention also teaches that any one of these three functions can be
`
`activated when the touch sensitive area detects a movement of an object with its
`
`starting point within the representation of the function on the menu area and with a
`
`direction from the menu area to the display area.
`
`With the purpose of providing a simple way of managing any application or
`
`JO
`
`the operations system, the present invention teaches that if the first function is
`
`activated, the display area is adapted to display icons representing services or
`
`settings, depending on the current active application. One of the icons always
`
`represents a "help"-service, regardless of application. The icons are adapted to
`
`represent services or settings of the operations system of said computer unit, such

`
`3
`
`as background picture, clock, users. help, etc. if no application is currently active
`
`on the computer umt.
`Selections of preferred service or setting is done by tapping on
`
`corresponding icon
`With the purpose of providing the access to a text input function in any
`
`5
`
`application in the computer unit, the present invention teaches that when the
`second function is activated, the display area ,s adapted to display a keyboard and
`
`a text field,
`If a text passage in an active application is highlighted, then this text
`
`10 passage is displayed in the text field for editing through the keyboard and that the
`
`highlighted text passage is replaced by the edited text passage when the second
`
`function is deactivated_
`
`If no text passage in an active application is highlighted, then the text field
`
`is available for inputting and editing of text through the keyboard.
`
`15
`
`In the case of the latter the first function can be activated, or the second
`
`function can be closed, in which a choice of saving or deleting the inputted text is
`
`given. The choice of saving the inputted text results in an activation of the first
`
`function. In this case the first function will present services or settings available for
`
`the inputted text, such as saving the inputted text for later use, using the inputted
`
`20
`
`text as telephone number in a telephone application, or sending the inputted text
`
`as message in communications application.
`
`In order to provide a task and file management in a user interface for a
`handheld mobile computer, the present invention teaches that, if the third function
`is activated, the display area is adapted to display a list with a library of available
`
`25 applications and files on the computer unit A selection of an application will start
`
`the application, and a selection of a file will open the file in an application intended
`
`for the file.
`
`A selection of an application or a file is done by moving the object so that
`
`the representation of desired application or file is highlighted, removing the object
`
`30
`
`from the touch sensitive area, and then tapping on the touch sensitive area.
`
`According to the present invention a navigation in the list is performed by
`
`moving the object in a direction towards the top of the list or towards the bottom of
`
`the list. This will cause the marking to mo"e in the same direction. The speed of

`
`4
`
`the movement of the marking is lower than the speed of the movement of the
`
`object, with the purpose of making the navigation easier.
`The user interface of the present invention is specifically adapted to be
`
`used with a small computer unit where the size of the touch sensitive area is in the
`
`5 order of 2-3 inches, The user interface is also adapted to be operated by one
`
`hand, where the object can be a finger, such as the thumb, of a user of the
`
`computer unit.
`
`Advantages
`Those advantages that can be primarily associated with a user interface or
`
`10
`
`a computer readable medium according to the present invention reside in the
`
`ability to establish a user-friendly interface for small handheld computers, both
`
`regarding general application set-up functions, text input functions, and file and
`
`task management.

`Description of embodiments at present preferred
`Figure 1 illustrates a user interface for a mobile handheld cornputer unit.
`
`s
`
`The user interface according to the present invention is specifically adapted to
`
`computer units comprising a touch sensitive area 1, which is divided into a menu
`
`area 2 and a display area 3. It should be understood that there are several
`
`different kinds of known touch sensitive displays and that the present invention
`
`10 does not depend on what kind of touch sensitive display that is used in relation to
`
`the inventive user interface.
`The computer unit is adapted to run several applications simultaneously
`
`and to present an active application on top of any other application on the display
`
`area 3. It should be understood that by simultaneously it is meant any technology
`
`15
`
`that will make it appear to a user of the computer unit that applications are run
`
`simultaneously and that the present invention does not depend on how this is
`
`realised, whether it is through time-sharing of one processor, parallel use of
`
`several processors, or any other technique.
`
`According to the present invention the menu area 2 is adapted to present
`
`20 a representation of a first 21, a second 22 and a third 23 predefined function.
`
`The first function 21 is a general application dependent function, the
`
`second function 22 is a keyboard function, and the third function 23 is a task and
`
`file manager.
`
`Figure 2 shows that any one of these three functions 21, 22, 23 can be
`
`25 activated when the touch sensitive area 1 detects a movement of an object 4 with
`
`its starting point A within the representation of a function on the menu area 2 and
`
`with a direction B from the menu area 2 to the display area 3.
`
`Figure 3 shows that if the first function 21 is activated, then the display
`
`area 3 is adapted to display icons 211,212,213,214,215,216 representing
`
`30
`
`services or functions depending on the current active application One of the icons,
`
`in the figure exemplified by icon 211, always represents a "help" -service.
`
`regardless of application. Any key that. because of lack of space on the display

`
`of any other reason is not shown on the display area of an active application, can
`
`be represented by one of the icons 212, 213, 214,215,216 that is shown when
`
`the first function 21 is activated.
`If for instance the active application handles a picture, then the icons that
`s are shown when the first function is activated can be services such as "save to
`disk", "send as SMS", or "delete" and they can be settings such as "resolution",
`
`"colour", or "brightness".
`If no application is currently active on the computer unit, then the icons
`
`211,212,213,214,215, 216 are adapted to represent services or settings of the
`
`10 operations system of the computer unit, such as background picture. clock, alarm
`
`215, users 213, help 211, etc.
`
`Figure 4 shows that selection of a preferred service or setting is done by
`
`tapping C, Don corresponding icon 213.
`
`Figure 5 shows that if the second function 22 is activated, then the display
`
`ts
`
`area 3 is adapted to display a keyboard 221 and a text field 222.
`
`Two different scenarios can be at hand when this function key is
`
`activated. A first scenario can be that a text passage in the active application is
`
`highlighted as the second function is activated If this is the case then the
`
`highlighted text passage is displayed in the text field 222 for editing through the
`
`20
`
`keyboard 221.
`
`The highlighted text passage is replaced by the edited text passage when
`
`the second function 21 is deactivated.
`
`A second scenario can be that no text passage in the active application is
`
`highlighted. If this is the case then the text field 222 is available for inputting and
`
`25 editing of text through the keyboard 221.
`
`In the case of the latter scenario, the first function 21 can be activated, or
`
`the second function 22 can be closed. If the second function 22 is closed then a
`
`choice of saving or deleting the inputted text is given, where the choice of saving
`
`the inputted text results in an activation of the first function 21.
`
`30
`
`As the first function 21 is activated with the second function 22 as currently
`
`active application the first function 21 will present services or settings available for
`
`the inputted text. such as saving the inputted text for later use, using the inputted
`
`text as telephone number in a telephone application, or sending the inputted text
`
`as message in communications application, such as e-mail, SMS, or fax.

`
`Figure 6 shows that if the third function 23 is activated, then the display
`
`area 3 is adapted to display a list 231 with a library of available applications and
`
`files on the computer unit.
`A selection of an application will start the application, and a selection of a
`
`5
`
`file will open the file in an application intended for the file_ The name of a selected
`
`file can be edited by activation of the second function 22 as the file is highlighted.
`
`Figure 7 shows that a selection of an application or a file is done by
`moving E the object 4 so that the representation of desired application or file is
`
`highlighted, removing F the object 4 from the touch sensitive area 1. and then
`
`10
`
`tapping G, Hon the touch sensitive area 1.
`
`An application or file is highlighted by placing some kind of marking 232 on
`
`the representation of the application or file_ This marking can be done in different
`
`ways, for example by putting a frame around the representation of the application
`
`. or file, as shown in the figure, or by inverting the representation of the application
`
`15 or file.
`
`It should b understood that all lists in the computer unit, such as a list of
`
`contact information in an address book, a list of e-mail messages in a mailbox, or
`
`a telephone log, can be managed in the above described manner.
`
`The list 231 can be adapted to present only files or only applications In
`
`20
`
`this case, the top area of the list 231 can present a field 233 through which the
`
`content if the list 231 can be altered. If the list only presents files, then the field 233
`
`can display a representation of a task manager and a selection of the field 233 will
`cause the list 231 to alter to present only applications, and if the list 231 only
`
`presents applications, then the field 233 displays a representation of a file
`2s manager and a selection of the field 233 will cause the list 231 to alter and present
`only files.
`
`Figure 8 shows that navigation in the list is performed by moving the
`
`object 4 in a direction I towards the top 231a of the list 231 or towards J the bottom
`231b of the list 231. This movement I, J of the object 4 will cause the marking 232
`to move K, L in the same direction. The speed of the movement K, L of the
`
`30
`
`marking 232 is lower than the speed of the movement I, J of the object 4.
`
`Figure 9 shows that if the number of applications and/or files in the list 231
`
`exceeds the number of applications and/or files that can be presented on the
`
`display area 3, and if the object 4 is moved to the top or bottom position of the

`
`display area, then lifted, replaced on the display area, and then again moved to
`
`the top or bottom of the display area, then the content of the display area will be
`
`replaced one whole page, meaning that if the object 4 is positioned N at the
`
`bottom 3b of the display area 3, then lifted, replaced on the display area 3, and
`
`5
`
`then again moved M to the bottom 3b of the display area 3, then the content 31 of
`
`the display area 3 will be replaced P by the following applications and/or files 32 in
`
`the list 231. In the same way, but not shown in the figure, if the object is position at
`
`the top of the display area, then lifted, replaced on the display area 3, and then
`
`again moved to the top of the display area, the content of the display area will be
`
`10
`
`replaced by the preceding applications and/or files in the list.
`
`Figure 10 shows that if the object 4 is removed Q from a first position 33
`
`on the display area 3 and then replaced R, Son a second position 34 on the
`
`display area 3, then the navigation can be continued T from the second position
`
`34.

`
`Figure 11 shows that moving U the object 4 from the left of the display
`
`area 3 to the right of the display area 3 moves the active application, function,
`
`service or setting on one step forwards. Figure 12 shows that, in a similar manner,
`
`the active application, function, service or setting is closed or backed one step by
`
`moving V the object 4 from the right of the display area 3 to the left of the display
`
`20 area 3.
`
`As shown in figure 1, the menu area 2 is positioned at the bottom of the
`
`touch sensitive area 1. The representation of the first function 21 is positioned at
`
`the left side of the menu area 2, the representation of the second function 22 is
`
`positioned at the middle of the menu area 2, and the representation of the third
`
`2s
`
`function 23 is positioned at the right side of the menu area 2.
`
`As shown in figure 13, the present invention relates to a user interface for
`
`a hand held mobile unit that preferably can be manageable with one hand. Hence
`
`the present invention teaches that the user interface is adapted to a touch
`
`sensitive area 1 with a size that is in the order of 2-3 inches, meaning the diagonal
`
`30 distance W between two corners of the touch sensitive area 1.
`
`The user interface is adapted to be operated by one hand, where the
`
`object 4 can be a finger, such as the thumb shown in the figures, of a user of the
`
`computer unit. It should be understood though that the present invention might
`
`also be used with another object, such as a pen or other pointing device.

`
`According to one preferred embodiment of the present invention the
`
`computer unit is covered with an enclosure 5, which is provided with an opening
`
`51 for the display area 3, and where the representations of the menu area 2 is
`
`printed on top of the enclosure 5. It should be understood that the opening 51
`
`5 might be a transparent part of the enclosure 5 or that it might be an open aperture
`
`depending on among other things technical considerations pertaining to the touch
`
`sensitive area 1 .
`
`This makes it possible to allow the enclosure 5 to be removable and
`
`exchangeable.
