Description
1 2428503 TITLE: ELECTRONIC DEVICE INCLUDING A KEYPAD AND A METHOD
OF OPERATION
FIELD OF THE INVENTION
The present invention relates to an electronic device including a keypad and a method of operation. In particular, the invention relates to an electronic device having a display screen providing a displayed keypad comprising images of displayed keys and a touch sensitive screen associated with the display screen.
BACKGROUND OF THE INVENTION
Many electronic devices include amongst their various components a keypad which serves as a user interface to allow a user to enter instructions and data into the device. For example, mobile communications handsets are widely used to send radio communications and include a keypad to allow a user to enter information relating to the communications such as a telephone number to be called or a text or data message to be sent. Such handsets include mobile or cellular telephones, portable radios, PDAs (personal digital assistants) and the like. Other electronic devices which make extensive use of keypads include games stations.
Conventionally, keypads are formed of electro- mechanical keys. In many cases, these keys are arranged in a four by three matrix and are labelled with characters printed thereon. For example, for keypads used in Western Europe and North America, Arabic letters may be printed on the keys together with numerals 1 to 9, 0 or special symbols * or #. In other geographical regions the characters shown on the keys may be suited to the language used in that region. For example, a Chinese character set may be used for handsets for use in the Far East.
Producing electronic devices such as communications handsets having keypads with different printed character sets for use in different regions of the world significantly raises the cost of the product, in terms of the multiple product design, engineering, production and logistics work involved.
SUMMARY OF THE INVENTION
According to the present invention in a first aspect there is provided an electronic device as defined in claim 1 of the accompanying claims.
According to the present invention in a second aspect there is provided a method of operation in an electronic device, the method being as defined in claim 18.

FIG. 5 is a flowchart illustrating steps in a method of operation of the radio of FIGS. 1 to 4.
DESCRIPTION OF EMBODIMENTS OF THE INVENTION
FIG. 1 is a front view of a portable radio 100 for use in communications with other similar portable radios, which may be adapted in accordance with an embodiment of the invention. The portable radio 100 includes a speaker 101, a microphone 102 and a display screen 103 of an electrooptical display.
FIG. 2 is an enlarged front view of the display screen 103. The display screen 103 includes in a lower part 205 display of key images 206 (i.e. images of keys) making up a keypad. The display screen 103 includes in an upper part 204 display of other information such as conventional text information. Thus, the display screen 103 is operable to display other information in the upper part 204 whilst the key images 206 are being displayed in the lower part. Alternatively or in addition the display screen 103 may be operable to display, according to user selection, other information in place of the key images 206 in the lower part 205.
The key images 206 are arranged in a four by three matrix to represent a keypad. This is one example of a possible arrangement of the key images 206. Other arrangements, such as matrices other than four by three, may of course be used. The displayed key images 206 resemble the mechanical keys of a conventional keypad.
The characters displayed on the key images 206 include numerals and alphabetic letters, i.e. alphanumeric' characters. The displayed key images 206 can, in accordance with an embodiment of the invention, be formatted or configured by a user as described later.
Although FIG. 2 shows the upper part 204 and the lower part 205 as parts of the same display by the display screen 103, the parts employed to display respectively a keypad and other user information could, as will be apparent to those skilled in the art, be provided by separate display screens.
FIG. 3 is a front view of an overlay 300. The overlay 300 is made of thin, flexible polymeric material. The overlay 300 includes transparent regions 301 which are arranged in a four by three matrix in the form of shapes which match the shapes of the key images 206 displayed or to be displayed on the display screen 103. Other parts of the overlay 300, e.g. side regions 302 and 303, may be translucent or opaque as shown in FIG. 3 to contrast with the transparent regions 301.
The overlay 300 is fitted over the display screen 103 50 that the regions 301 are arranged to lie over the corresponding key images 206. In practice, the overlay 300 may be fitted on the display screen 103 before the key images 206 are displayed, although it may be preferable to apply the overlay 300 when the configuration of the key images 206 has been selected and set as described later. The display screen 103 may be in a recess of a casing of the radio 100 thereby facilitating fitting of the overlay 300. The overlay 300 may be temporarily or permanently fixed in place, e.g. using a suitable adhesive around its edges.
The overlay 300 has two main functions. Firstly, its regions 301 provide suitable indication of keys displayed as key images 206. For instance the regions 301 may help a user easily to find where the keys are located, and thereby facilitate tactility of the keys.
Furthermore, the regions 301 provide physical feedback that a displayed key has actually been touched.
Secondly, the overlay 300 provides an environmental protection barrier for the display screen 103, e.g. against extremes in temperature and humidity and against mechanical shock. This is beneficial if the display screen 103 includes a fragile touch screen as described later.
FIG. 4 is a block schematic diagram of a layout 400 of operational components of the radio 100. The main operations of the radio 100 are controlled by a controller 401 which operates in conjunction with a timer 409 which synchronises operations and a memory 410 which stores data and programs used within the radio 100. A processor 402 processes information to be included in RF signals sent and received by a transceiver 403. The processor 402 extracts information, e.g. electrical signals representing speech signals, from a received RF signal detected by the transceiver 403 and passes the information to an audio output 404 which is a transducer such as a speaker which converts the information to an output audible form for delivery to a user. An audio input 405 is a transducer which converts an input audio signal, e.g. in the form of speech, into an electrical form. The electrical signal is delivered to the processor 402 in which it is processed for sending in a RF signal by the transducer 403. A battery 411 provides operation power to all operational components of the radio 100.
An electro-optical display 407 is shown in FIG.4.
This incorporates the display screen 103 shown in FIGs.
1 and 2 by which visual information is displayed to a user. The display 407 is driven by (receives operational voltages from) a display driver 406 working under the control of the controller 401. The display 407 also incorporates a touch screen 408 formed over the lower part 205 of the display screen 103 as shown in FIG. 2.
The touch screen 408 together with the key images 206 displayed on the display screen 103, as well as the overlay 300 shown in FIG. 3, forms a user electronic or soft' keypad. When a user selects a particular character of this keypad by touching part of the touch screen 408 overlying one of the key images 206, an electrical signal is generated and is sent to the controller 401. The signal indicates which part of the touch screen 408 corresponding to one of the key images 206 has been selected.
As seen in FIG. 2, each of the key images 206 represents more than one character. This is similar to sharing of keys by characters on a conventional mechanical keypad. The appropriate character of the set to be indicated in a key image 206 may be selected by operation, in conjunction with the appropriate key image 206, of a shift button (not shown) which may be a conventional mechanical button or may comprise a soft' key (displayed key image) which is part of the keypad comprising the touch screen 408.
The touch screen 408 may be one of the touch screen types known in the prior art. Generally, such screens produce an electrical signal to indicate a localised region which has been touched by a user, the region corresponding to a key' displayed as a key image behind that region on the display screen 103. The touch screen 408 may for example be a screen which senses a local change or variation in an electrical property caused by touch by a user's finger. For example, the property changed may be electrical capacitance, conductivity or resistivity. Alternatively, or in addition, the touch screen 408 may for example be a screen which senses a local change or variation in an electrical property, such as conductivity or resistivity, due to a pressure change when an area corresponding to a key (a displayed key image 206 behind the area) is touched by a user to indicate selection of the corresponding key. Any other known form of touch screen may alternatively be used.
In accordance with an embodiment of the invention, the controller 401 may issue signals (selection signals') to select the configuration of the key images displayed on the display screen 103. The signals may be produced by the user selecting a particular configuration option. For example, the display screen 103 in the upper part 204 may display a menu of configuration options available to a user. A particular option of a displayed menu or set may be selected by operation by a user of a selection button (not shown) which may be a conventional mechanical button or a soft' key which is part of the keypad comprising the touch screen 408.
The option selected may be from one of a plurality of sets or menus of options available to be chosen by a user concerning the configuration of the displayed key images 206. The following may form sets or menus from which options may be selected: (1) language, e.g. Arabic or Chinese, of the characters included in the key images 206; (ii) selection of either a regular set of characters or alternatively a special set of characters e.g. mathematical or other special symbols, for inclusion in the key images 206; (iii) orientation of the key images as a set, e.g. by 90 degrees or by 180 degrees, relative to the display screen 103; (iv) one or more of: a font of the characters; a colour of the characters; a size of the characters; a spacing of the characters; a boldness of the characters; and whether or not the characters are italicised; in respect of the characters included in the key images 206; (v) a colour of a key image background, and a level of brightness.
The keypad formed by the display screen 103, the touch screen 408 and the overlay 300 beneficially allows a user (or a local supplier) to select how the keys' (key images 206) are to be configured on the display screen 103 and thereby avoids the need for manufacture of different radio types (with different fixed mechanical keypads) for different geographical regions.
FIG. 5 is a flowchart illustrating steps sumrnarising a method of operation 500 of the radio 100 of FIGS. 1 to 4. The method of operation 500 includes a step 501 in which information including images of keys, the key images 206, representing keys of a keypad for selection by a user to provide input instructions or data is displayed to a user on the electro-optical display screen 103. In a step 502, one or more individual displayed key images 206 are selected by a user by touching by the user of one or more areas of the touch screen 408 associated with the display screen 103 and a step 503 in which entry of a signal by a user at a user interface, namely the touch screen 408, changes (or selects) via the controller 401 a format or configuration of the displayed key images 206. Although step 503 is shown in FIG. 5 as following steps 501 and 502, it could alternatively be applied prior to one or both of steps 501 and 502.
Although the invention has been illustrated by reference to application in a portable radio, use of the invention is not limited to that particular application.
Embodiments of the invention may be implemented in any electronic device which includes an electronic keypad as a user interface, particularly other wireless communication devices in the form of handsets, such as portable or mobile telephones or PDAs, as well as games stations.
