Definitions
- the invention relates to the use of touchscreen devices provided with an indicator means and particularly to editing character strings, such as network addresses, with the indicator means.
- a wireless terminal such as a mobile station
- a mobile station is not used only for calls, but a mobile station can also be used to process and display information in an increasingly versatile manner.
- One of the most desirable properties of a wireless terminal is the ability to use Internet services, such as email and graphic www pages.
- Many other small portable terminals e.g. PDA devices, Personal Digital Assistant
- PDA devices personal Digital Assistant
- Many other small portable terminals also comprise means, e.g. a WLAN card or a wired connection, for setting up an Internet connection.
- Touchscreens are increasingly used in both PDA devices and mobile stations.
- buttons are displayed on the screen, and touching them activates functions associated with the selection element.
- Many functions can be used by selecting suitable alternatives from menus and activating the desired function or setting by touching that particular point on the screen.
- the use of some applications is subject to text being entered via the touchscreen.
- the keys of a QWERTY keyboard can be modelled onto a touchscreen (also known as a virtual keyboard).
- handwriting identification is also often used.
- the small size of the screen and the simultaneous display of several selection elements on the screen results in the elements on displayed on the screen being substantially small. Due to the small keys and handwriting identification, a touchscreen is generally used by means of a small writing device, i.e.
- a stylus e.g. a small pen-shaped object.
- editing the network address (URL address) of an Internet browser into the desired form is often laborious and cumbersome.
- Internet browsers generally use predictive text entry, i.e. when the user of the device starts to write a new network address in the address field of the browser, the browser's history data are searched for such a network address that, at least as regards the beginning of the address, comprises the same character string as the character string of the network address entered up to that point by the user.
- the browser program shows the network address found in the history data in the address field suggesting it for use to the user either as such or allowing the user to edit the character string in a suitable manner to generate the desired address.
- a solution is known from what are known as palm-size computers (e.g. PalmTM OS4) for editing a character string, such as an Internet address, displayed on a screen, wherein the user first selects the part of the character string to be deleted by pointing ('painting') said characters with a stylus, after which the user has to either depress the 'backspace' key of the virtual keyboard or enter a symbol indicating the corresponding purpose in a handwriting entry field. The part of the character string selected by means of the backspace function is deleted.
- the browser program has to be separately activated by depressing the stylus if the browser program is to start loading the network address defined by the edited character string.
- the user has to perform three separate tasks with the stylus in order for the browser program to start loading. From the point of view of usability, this is generally considered very laborious and slow. Accordingly, there is need for a simpler way of editing a character string on a touchscreen.
- said character string is a network address displayed in the address field of a browser program.
- loading the network address according to the edited character string is initiated automatically by said browser program in response to the editing of the character string.
- said character string is displayed in the address field of the browser program based on predictive address entry.
- the touchscreen is configured to identify the duration of the indication in relation to a predetermined limit value, whereby said automatic loading of the network address is initiated in response to the duration of the indication exceeding the predetermined limit value.
- the touchscreen is configured to identify the direction of movement of the indication in relation to a predetermined limit value, whereby said automatic loading of the network address is initiated in response to the direction of movement being within the limits set by the predetermined limit value.
- the indication is arranged to be performed as a substantially perpendicular back and forth movement between two characters comprised by the character string.
- said automatic loading of the network address is initiated in response to the indicator means being released from contact with the touchscreen.
- An advantage of the method and device of the invention is that the user is able to use one indication function of the indicator means to edit the character string displayed on the screen, and in some embodiments also to initiate a function associated with the application, such as loading a new network page.
- a further advantage is that the user does not need to open the text entry function to edit the character string displayed on the screen.
- the method provides the user with an intuitive manner of editing the character string displayed on the screen. In accordance with an embodiment of the in- vention, the editing does not take place until the user detaches the indicator means from the touchscreen.
- the advantage here is that the user is able to check the correct indication point as long as the indicator means is in contact with the text field comprised by the touchscreen.
- the user is able to preferably change the indication point by gliding the indicator means along the character string. This speeds up the use of the device and reduces erroneous selections.
- FIG. 1 is a block diagram of an electronic device to which the invention can be applied;
- Figure 2 shows a typical user device of a touchscreen of a portable device in a simplified manner;
- Figures 3a to 3c show an example of the editing of a character string according to the invention;
- Figure 4 is a flow diagram of a method according to some embodiments of the invention of editing a character string in association with an Internet browser.
- FIG. 1 shows a block diagram of an electronic device (ED) comprising a touchscreen, the device being for instance a wireless mobile station or a PDA device to which the invention is applicable.
- the electronic device (ED) comprises a central processing unit (CPU), memory (MEM) and an I/O system (I/O). All necessary information is stored in the memory (MEM) of the device.
- the memory (MEM) comprises a read-only memory partition, which may be ROM memory, for example, and a write memory partition, which may be composed of a RAM (Random Access Memory) and/or FLASH memory, for example.
- the device communicates via the I/O system (I/O) with other devices, a network and a user, for example.
- the user interface (Ul) which is part of the I/O system (I/O), comprises the necessary interface for communication with the user, such as a screen, keys, a loudspeaker and/or a microphone, for example.
- the screen of the device is a touchscreen.
- the data received from the different components of the device are transferred to the central processing unit (CPU), which processes the re- ceived data in the desired manner.
- the electronic device (ED) is illustrated as an integrated device comprising all necessary components in one unit.
- the electronic device is, however, possible to implement the electronic device as a device system comprising a plurality of component units functionally connected to each other.
- the screen, the microphone/loudspeaker, and at least part of the memory can be implemented as separate units, which are connected to the rest of the device system either by a wired connection or wirelessly, for example via a Bluetooth connection.
- any component of the device system can be implemented as a separate unit.
- the invention is applicable for use substantially with all touchscreen types, but the touchscreen type employed is not as such essential as regards the implementation of the invention.
- FIG. 2 shows in a simplified manner the user interface of a small-sized, typically portable device comprising a touchscreen.
- the screen 200 of the device is a touchscreen, in which some keys 202 of the QWERTY keyboard and function keys 204 are modelled at the lower edge of the screen.
- the screen or the application used in the device comprises a text field 206 for entering text or editing text existing in the text field based on either handwriting identification or by means of a keyboard. Both alternatives are based on the use of an indicator means, i.e. a stylus 208.
- an indicator means i.e. a stylus 208.
- the user By activating a letter key 202, i.e. selecting it with the stylus 208, the user is able to enter letters in the device via the keyboard, and thus write text.
- handwriting identification the user writes text freehand in a field comprised by the touchscreen 200, the field being the same as the text field 206 displaying the actual text or a separate write field into which characters are written freehand and then, after identification, displayed in the text field 206.
- FIG. 3a A method for editing text displayed on a screen and for activating a related application according to some embodiments is illustrated next with reference to Figures 3a to 3c.
- the starting point in this example is an Internet browser program comprising predictive address entry functionality, known per se.
- the user enters, in the address field of the browser program, the initial part of the address of the network page he wants to load, either by handwriting identification or via a keyboard.
- the user writes www.nokia.c.
- the predictive address entry functionality of the browser program finds at least one suitable address from the history data of the browser program, and it typically suggests the last-used address.
- the browser program suggests, as the last-used address, the address www.nokia.com/press/s4826thgsaldag.asp%d1l/index.html shown in Figure 3b.
- this network page is not the one the user wants to load, and it is thus necessary to edit the character string comprised by the address.
- the user wants to load the network page www.nokia.com/press/, whereby, in accordance with the invention, the user uses the indicator means to depress the address www.nokia.com/press/s4826thgsaldag.asp%d1l/index.html of the address field of the browser program at the point after the word press/ in accordance with Figure 3c.
- the last part of the address after the word press/ can be preferably displayed fleetingly for instance on a darkened background, after which it is automatically deleted.
- the delay between the indication and the deletion is preferably sufficiently long for the user to have time to detect if he pressed the address character string at the correct point. Displaying the part of the character string to be deleted on a darkened background or in some other manner intuitive for the user helps the user preferably to detect if the marked point of the character string is correct.
- the touchscreen of the device is configured to define the duration in time of the contact of the indicator means and to compare it with a limit value stored in a memory. A contact longer in time than the limit value activates a function associated therewith, such as the deletion of the end of the character string or the loading of a net- work page according to the new address associated with the deletion. In association with this, in accordance with an embodiment, the activation of the function does not take place until the user detaches the indicator means from the touchscreen.
- the touchscreen of the device is configured to define the direction of movement of the indicator means and to compare it with a limit value stored in a memory.
- the indication point can be marked for instance with a substantially perpendicular movement of the indicator means.
- the perpendicular movement is to be performed back and forth.
- the perpendicularity of the movement can be determined from the derivates of the changes of the contact points of the indicator means, allowing the limit value to be set for instance such that the angle of change is not to exceed for instance 10 degrees in relation to the side edge of the touchscreen.
- the perpendicular movement should preferably be performed between the characters at which the end of the character string is to be deleted, which is also for the user an intuitive manner of 'sawing' the character string in two.
- the invention is not limited hereto, but it can be applied to the editing of any character string in a device provided with a touchscreen, whereby the application wherein the character string is edited can also be other than a browser program.
- the editing of a character string according to the invention can be applied for instance to cell definitions in a spreadsheet program and related calculation formulas, whereby the use of the character string editing of the invention can preferably automatically activate the update according to the changed cell definitions in the table.
- the invention when the invention is applied to the editing of a network address of an Internet browser, the invention can also be applied to browsers that do not support predictive address entry. In this case, the network address is edited based on the address in the address field of the browser at each particular time.
- Figure 4 illustrates, by means of a flow diagram, some of the above-described embodiments when the address field of an Internet browser is edited in accordance with the invention.
- the starting point (400) is a situation where a network address displayed on a screen (402) is defined in the address field.
- the network address can be an address suggested by the predictive address entry of the browser or it can be the address of the network page last loaded by the user.
- the process proceeds to the detection of a contact of an indicator means (stylus) (404).
- the application program determines the contact parameter of the indicator means via the touchscreen, such as the duration in time of the contact, and compares it with a preset limit value (406). If the duration of the contact is not sufficiently long (shorter than the limit value), the same network address continues to be displayed on the screen (402). If again the duration in time of the contact is at least as determined by the limit value, the characters after the indication point are deleted from the character string of the network address (408).
- the contact parameter of the indicator means can also be for instance a value determining the direction of movement of the contact, the value being compared with the limit value stored in the memory, whereby the contact movement should be sufficiently perpendicular, for example, in order for the characters after the indication point to be deleted from the character string of the network address (408).
- the browser program then automatically initiates the loading of the network address according to the edited character string (410).
- the functionality of the invention can be implemented in a portable terminal, such as a mobile station, comprising a touchscreen, preferably as a computer program, which, when executed in the central processing unit CPU, makes the terminal perform tasks according to the invention.
- the computer program can be most preferably implemented as a plug-in to be loaded into a terminal or an application program.
- the functions of the computer program SW can be divided into several separate software components communicating with each other.
- the computer program may be stored in any memory means, e.g. the hard disk of a PC or a CD-ROM, from which it can be loaded into the memory MEM of the mobile station MS.
- the computer program may also be loaded via a network for instance by using the TCP/IP protocol stack.
- An alternative is to use hardware solutions or a combination of hardware and software solutions to implement the inventive means.
- the computer program SW comprises at least a computer program code section for editing a character string in response to an indication performed with an indicator means such that the characters after the indication point are deleted from the character string.
- the computer program product is a browser program or a plug-in thereof to be loaded into a terminal, and said character string is a network address displayed in the address field of the browser program, whereby the computer program product comprises a computer program code section for initiating the loading of the network address according to the edited character string by said browser program automatically in response to the editing of the character string.
