Definitions
- This invention relates to guiding a user to select keys on a keyboard.
- the invention is particularly useful for, but not necessarily limited to, guiding a user to select valid sequences of Pin Yin characters.
- a frequently used interface between man and machine is a display screen.
- Such screens are not just used for one way communication, that is lo display data to the user, but also as means for
- One of the main growth areas in touch screen devices is in small portable devices, such as mobile telephones, persona] digital assistants
- buttons for instance buttons, voice recognition, hand writing recognition virtual buttons (such as a virtual keyboard or virtual keypad displayed on the touch screen), etc.
- buttons for instance buttons, voice recognition, hand writing recognition virtual buttons (such as a virtual keyboard or virtual keypad displayed on the touch screen), etc.
- voice recognition for instance buttons, voice recognition, hand writing recognition virtual buttons (such as a virtual keyboard or virtual keypad displayed on the touch screen), etc.
- hand writing recognition virtual buttons such as a virtual keyboard or virtual keypad displayed on the touch screen
- various buttons appear on the touch screen and touching
- touch screens are well known in the art and touch detection can be by way of many well-known systems, such as capadtive or inductive sensing or contact switches.
- a method for guiding a user of an electronic device to select keys on a keyboard of a 15 user interface of the device comprising: receiving a reference alphanumeric character, input at the keyboard of the user interface, the reference alphanumeric character identifying a first part of at least one syllable; searching a database of valid syllables or words to identify 20 valid alphanumeric characters that can immediately follow the reference alphanumeric character; and emphasizing keys on the keyboard that represent the valid alphanumeric characters thereby guiding the user to select one of the keys representing one of said valid alphanumeric characters.
- the emphasizing enlarges keys, relative to other keys, on the keyboard that represent the valid alphanumeric characters.
- the emphasizing illuminates keys, relative to other keys, on the keyboard that represent the valid alphanumeric characters.
- the method is further characterized by the reference alphanumeric character and valid alphanumeric characters form part of Pin Yin syllables and the searching is characterized by the database containing Pin Yin syllables associated with Chinese characters. 5
- the method includes a further step of displaying on a display, the Chinese Characters corresponding to the reference alphanumeric character and valid alphanumeric characters.
- the method includes a further step of allowing a user to select a desired Chinese character having a Pin Yin representation starting with the reference alphanumeric reference character, the desired Chinese character being one of the Chinese Characters corresponding to the reference alphanumeric character. 15
- the method is further characterized by receiving another alphanumeric character, the another alphanumeric character being one of the valid alphanumeric characters identified by the keys emphasized at the emphasizing step. 20
- the method is further characterized by effecting the following steps: searching the database of valid syllables or words to identify valid alphanumeric characters that can immediately follow the
- Fig. 1 is a schematic block diagram of an electronic device in accordance with the invention.
- FIG. 2 is a flow diagram illustrating a method for guiding a user to select keys on a keyboard of a user interface of the device of FIG. I;
- Figs. 3 to 12 illustrates operation of the user interface during 10 steps of the method of FIG. 2.
- an electronic device 1 the device 1 illustrated is a radio communications device comprising a radio frequency communications unit 2 coupled to be in communication with a processor 3.
- An user interface in the form of an
- interactive display or touch screen 5 typically a Liquid Crystal Display
- an optional keypad 6 are also coupled to be in communication with the processor 3.
- the processor 3 includes an encoder/decoder 11 with an associated 25 Read Only Memory (ROM) 12 storing data for encoding and decoding voice or other signals that may be transmitted or received by electronic device 1.
- the processor 3 also includes a micro-processor 13 coupled to both an encoder/decoder ]] and an associated character Read Only Memory (ROM) ' 14.
- Micro-processor 13 is also coupled to a Random 30 Access Memory (RAM) 4 and a static programmable memory 16.
- static programmable memory 16 stores, amongst other features and functions, a phone book database of numbers and associated identifiers (names ot people associated with each of the numbers).
- rrucro-processor 13 Auxiliary outputs of rrucro-processor 13 are coupled to an alert module 15 that typically contains a speaker, vibrator motor and associated drivers
- the character Read only memory 14 stores code for decoding or encoding text messages that may be received by the communication unit 2, input at the touch screen 5 or optional keypad 6
- the 10 character Read Only Memory 14 also stores operating code (OC) for microprocessor 13 and a template set of characters for character recognition
- OC opera tang code
- the radio frequency communications unit 2 is a combined receiver
- the communications un t 2 has a transceiver 8 coupled to antenna 7 via a radio frequency amplifier 9
- the transceiver 8 is also coupled to a combined modulator/demodulator
- FIGs. 2 to 12 there is illustrated a method 20 for guiding a user of the electronic device 1 to select character keys represented on a or soft keyboard 31 on the user interface an the form of the touch screen 5 For instance, if a user wished to enter two Chinese Characters " %" by Pm Ym text entry, then " iB5 " is
- the touch screen 5 will typically be displaying the indicia as shown in Fig 3 As shown, the touch screen 5 has the soft keyboard 31 in a well know QWERTY layout, a
- the method 20 then provides for receiving a reference alphanumeric character at a receiving an alphanumeric character step 22 that is input at the keyboard 31, the 5 reference alphanumeric character provides for identifymg a hist part of at least one syllable ("gao")
- step 22 the reference alphanumeric character "g" is received by a user selecting one of the keys 32 of the soft keyboard 31 that identifies "g"
- a searching step 23 the method then provides for searching a database, stored m the memory 16, of valid syllables or words or Chinese characters to idenbfy valid alphanumeric characters that can immediately follow the reierence alphanumeric character "g" Also, the searching attempts to
- step 24 displays, m the Chinese Character display region 35, Chinese characters that have a their first P Ym alphanumeric character corresponding to the reference 10 alphanumeric character "g"
- a user may select a desired Chinese character displayed in Chinese Character display region 35 by simply pointing to one of the Chinese characters displayed on the
- the searching step 23 searches for valid alphanumeric characters that can immediately follow the mput string "ga” Also, the searching attempts to identify v alid syllables or words or Chinese characters
- the processor 3 controls the touch -screen to emphasize some of keys 32, the keys representing the Pin Yin valid alphanumeric characters 5 "i","o” and “n".
- the string "ga” is illustrated in the display region 33.
- the Chinese characters that have a their first Pin Yin alphanumeric character corresponding to the string "ga" are also displayed in the Chinese 10 Character display region 35.
- a user may select a Chinese character displayed in Chinese Character display region 35 by simply pointing to one of the desired Chinese character displayed on the
- test step 25 provides for allowing a user to select a desired Chinese character having a Pin Yin representation starting with the reference alphanumeric reference character, the desired Chinese character being one of the Chinese
- step 26 displays the desired Chinese character in the sentence display region 36 and a clearing step 27 clears the Pm Ym display region 33 After completion of step 27 then touch 5 screen 5 would display what is typically illustrated Fig 7
- a test step 28 determines if the user has finished inputting characters, this may be done by a time-out procedure, or by the user activating a function of the device 1 Since the user still desires to input the
- the present invention provides for guiding a user to select the appropriate keys during text entry This is especially useful 25 when a user is not familiar with the ke board layout
