From the point of view of the user, it is easier to keep track of the whole picture of the application view while zooming. Further, the invention is quickly understandable and easy to learn and use.
In the following, the invention will be described in greater detail with reference to preferred embodiments and the accompanying drawings, in which
The embodiments of the invention are applicable to electronic devices, such as mobile stations used as terminals in telecommunication systems comprising one or more base stations and terminals communicating with the base stations, for example. The devices may be used for short-range communication implemented with a Bluetooth chip, or an infrared or WLAN connection, for example. The electronic device is, for example, a portable telephone or some other device including telecommunication means, such as a portable computer, a personal computer, a handheld computer or a smart telephone. The portable electronic device may be a PDA (Personal Digital Assistant) device including the necessary telecommunication means for establishing a network connection, or a PDA device that can be coupled to a mobile telephone, for instance, for a network connection. The portable electronic device may also be a computer or PDA device including no telecommunication means.
The functions of the device are controlled by means of the input device 104, such as a mouse, a hand-held locator operated by moving it on a surface. When using a mouse, for example, a sign or a symbol shows the location of a mouse cursor on the display 102 and often also the function running in the device, or its state. It is also possible that the display 102 itself is the input device 104 implemented by means of a touch screen such that the desired functions are selected by touching the desired objects visible on the display 102. A touch on the display 102 may be carried out by means of a pen, a stylus or a finger, for example. The input device 104 can also be implemented by using eye tracking means where detection of eye movements is used in interpreting certain control commands.
The processing unit 100 controls the functions of the user interface and is connected to the display 102 and configured to show different application views on the display 102. The processing unit 100 receives control commands from the input device 104. The input device 104 is configured to give control commands for browsing in application views shown on the display 102. The application views may be views into different web pages on the Internet, views from any application programs run in the device or any other application views that may be shown on the display 102. The navigating or browsing of the application views may include scrolling the application view in any direction, for example horizontally or vertically, zooming in on the application view to get a better view of the details of the application view or zooming out on the application view to get a more general view of the whole application view.
The browsing functions operate such that the desired functions, such as scrolling or zooming, are first selected by means of the input device 104. Then, the processing unit 100 interprets the detected selections, performs given software functions based thereon and, as a result of the performed software functions, displays a given application view on the display 104.
In an embodiment of the invention, the processing unit 100 first displays an initial application view on the display 102. The displayed initial application view may be a view to an Internet page or to a document, for example. The displayed initial application view may be the whole view of the page/document or a view to at least part of the page/document.
The processing unit 100 is configured to provide a browse control area displayed on the display, the browse control area comprising a zooming block for controlling software functions for zooming. The processing unit 100 is then configured to detect a drag function on the zooming block. The drag function may be detected on the basis of a touch on the display 102, for example. Alternatively, the drag function may be detected by means of the input device 104, such as a mouse or a pen. Based on the detected drag function on the zooming block the processing unit 100 is configured to perform software functions for zooming and to display a current application view on the basis of the software functions performed for zooming. Further, the processing unit 100 is configured to display a whole application view on the browse control area.
The initial application view may be a whole or a partial view into an Internet page, and the current application view after the zooming function may be a view into another part of the Internet page, for example.
The processing unit 100 continues to detect control commands indicated by the input device 102 and to detect drag functions on the zooming block. It is possible that each time a browser application is opened the browse control area is also provided on the display. It is also possible that the browse control area is opened separately by using an icon or a menu function or by tap-based activation.
Let us next study embodiments of the invention by means of
A display 102 is usually divided into different areas, each area having specific functions. Application views are shown in the largest areas 220A and 220B, for example. There may also be different bars 216, 218 for displaying different information or menus on the display 102.
In an embodiment there is provided a browse control area 200 displayed on the display 102. In an embodiment the browse control area 200 may be located at least partly on the application view on the display. The browse control area 200 comprises a zooming block 204 for controlling software functions for zooming. The browse control area 200 and the zooming block 204 may also be of any other shape than that of a square, such as a circle, for example.
In
When a user wishes to zoom in or out on the initial application view, he/she may select the zooming block 204 and drag it. A current application view is then displayed on the display on the basis of software functions performed for zooming in response to a detected drag function on the zooming block 204. In an embodiment, also the size of the browse control area 200 is adjusted on the basis of the detected drag function on the zooming block 204. For example, when the zooming block 204 of
The software functions for zooming are performed on the basis of at least one of the following: the amount of the detected drag function, the speed of the detected drag function, the direction of the detected drag function. In the example of
Starting from a situation shown in
As the whole application view is displayed on the largest area 208 of the browse control area 200, it is easy to maintain a general view of the whole zoomed document while zooming in or out. It is possible that the whole application view is displayed on the browse control area 200 only when a zoomed in application view on the basis of the software functions performed for zooming is displayed. The whole application view may also be displayed at all times on the largest area 208 of the browse control area 200.
In an embodiment, an indication block 202 is provided in the browse control area 200 for indicating the amount of current zooming. For example, in
In an embodiment, a drag function on the indication block 202 can be detected, and software functions for scrolling the initial application view to produce a current application view can be performed on the basis of the detected drag function on the indication block 202.
There may also be other control blocks in the browse control area 200 than those given in these examples.
The zooming block 204 and the indication block 202 may be dragged using an input device. For example, tapping on the desired block and holding a pen down while dragging the block may move the block to a desired location. The input device may be a touch screen and a stylus, for example, and the user may select the zooming block 204 by first touching the touch screen with the stylus. The stylus may then be moved along the surface of the touch screen to produce a dragging function associated with the selected zooming block 204. Thus the software functions associated with the selected block are performed on the basis of the drag function detected on the block. In an embodiment, the software functions performed are based on the amount of the drag function detected on the zooming block 204. In another embodiment, the software functions performed are based on the speed of the drag function detected on the zooming block 204. Thus, the direction and the length of the drag function may define attributes for the software functions. The software functions may be accelerated if the block is dragged farther away from the original point. The direction of the drag defines whether the view is zoomed in or out. Dragging to the right or up may zoom in, and dragging to the left or down may zoom out, for example.
The appearance of the browse control area 200, zooming block 204 and the indication block 202 may be set as desired. Appropriate colors, text, drawings or fill effects may be used to mark the blocks.
The browse control area 200, zooming block 204 and the indication block 202 may also be set to appear in a “ghost mode”, meaning for example that only essential elements, such as outlines of the blocks, are used to indicate different blocks. The whole browse control area 200 may also be semi-transparent, that is, the contents below the browse control area 200 are visible. The level of transparency may also be adjusted. Thus, the browse control area 200 does not cover so much of the application view shown on the display 102.
The location and size of browse control area 200 may be determined by using the user interface of the device, for example. It is possible that each time an application view is opened, the browse control area 200 is displayed in a given location, for example in the upper left corner of the display 102. The browse control area 200 may also be located on the different bars 216, 218 for displaying different information or in the largest area 220A, 220B of the display. The location of the browse control area 200 may also be changed at any time. The size of the browse control area 200 may also be set according to the needs of individual users of the device, for example. The user may choose between a large and a small browse control area 200, for example.
New ways of browsing application views efficiently with the browse control area was shown in the previous examples. Because of screen space limitations, for example, mobile Web users wish to utilize the full screen when viewing a Web page. It is essential to provide the users a full screen mode in which browser controls or large scroll bars do not cover the page content. Still, the most important browse control blocks should be easily accessible. The examples shown provide possibilities to steplessly zoom or scroll the application views with a single gesture of a stylus, for example.
The method starts at 300. In 302, an initial application view is displayed on the display. In 304, a browse control area is displayed on the display. The browse control area may be displayed automatically when the application view is shown on the display, for example. It is also possible that the browse control area is first shown as an icon on the display, then activated from a menu or on the basis of a tap-based activation on screen and selected when needed. The browse control area comprises a zooming block for controlling software functions for zooming. In 306, the whole application view is provided on the browse control area. In 308, if dragging of the zooming block is detected, 310 is entered. If dragging of the zooming block is not detected, the initial application view remains with the browse control area displayed on the display.
In 310, software functions associated with the zooming block are performed based on the detection of the dragging of the zooming block. In 312, a current application view is displayed based on the performed software functions. The method may continue by repeating of the steps from 308 to 312 until the application is closed, another function is selected, or the device is shut down.
In 408, if dragging of the indication block is detected, then 410 is entered. If dragging of the indication block is not detected, the initial application view remains. In 410, software functions for scrolling are performed on the basis of the detection of dragging of the indication block. In 412, a current application view is displayed on the basis of the performed software functions. The method may continue by repeating of the steps from 408 to 412 until the application is closed, another function is selected or the device is shut down.
The embodiments of the invention may be implemented in an electronic device comprising a processing unit operationally connected to an input device, for example. The processing unit may be configured to perform at least some of the steps described in connection with the flowcharts of
The computer program may be stored on a computer program distribution medium readable by a computer or a processor. The computer program medium may be, for example but not limited to, an electric, magnetic, optical, infrared or semiconductor system, device or transmission medium. The medium may be a computer readable medium, a program storage medium, a record medium, a computer readable memory, a random access memory, an erasable programmable read-only memory, a computer readable software distribution package, a computer readable signal, a computer readable telecommunications signal, and a computer readable compressed software package.
Even though the invention has been described above with reference to an example according to the accompanying drawings, it is clear that the invention is not restricted thereto but can be modified in several ways within the scope of the appended claims.
