With reference now to the drawings,
The example physical keyboard 14 may be used for text entry and telephony entry and is intended to marry well known keyboards, such as those used on computer or typewriter keyboards, with keypads, such as those used on touch tone phones or cellular phones, into a single arrangement. The example physical keyboard is designed to be readily familiar to a user because of this marriage. The keyboard 14 provides a first user interface that includes alphabetic characters 44 comprising a standard alphabetic format, such as QWERTY, QWERTZ, AZERTY, or DVORAK, among other known formats, for text entry, and a second user interface that includes numeric characters for telephony entry. Current standard alphabetic keyboard formats utilize 26 keys for alphabetic characters, as shown in
The preferred reduced physical keyboard is accomplished by utilizing fewer columns than a standard format keyboard. Because of this, the keyboard 14 is well suited for application on a housing form factor similar to that of a housing associated with a numeric-keypad-based mobile communication device. In particular, the reduced column keyboard 14 provides for reduced size devices without sacrificing speed and convenience to a user. The reduced key keyboard also allows for smaller devices that are more stylish and fashionable.
The second user interface of the example keyboard 14 includes numeric characters that correspond to a phone pad 42, including the numbers 0-9. It is preferred that the array of numbers be presented on the keyboard in the format of a standard numeric phone key arrangement 42, depicted in
In one embodiment, the numeric phone key arrangement 42 may also utilize a surface treatment on the surface of the center “5” key in the form of a raised bump or recessed dimple 43. This bump or dimple 43 is typically standard on telephones and is used to identify the “5” key through touch alone. Once the user has identified the “5” key, it is possible to identify the remainder of the phone keys through touch alone because of their standard placement. The bump or dimple 43 is depicted in
The fourth row 56 may also include the symbols “*” and “#”, although these symbols may alternatively be positioned at other locations on the keyboard 14, as shown in
In an alternative embodiment, shown in
The keyboard 14 may further include symbols and functions that are typically utilized with keyboards. Example symbols include “.”, “,”, “;”, ““”, “””, “:”, “?”, “/”, “”>, “<”, “!”, “@”, “˜”, “$”, “%”, “^”, “&”, “(”, “)”, “_”, “−”, “+”, “=”, “[”, “]”, “{”, “}”, “|”, and “\”, among other known symbols. Example functions include “tab”, “caps lock”, “shift”, “control”, “alt”, “return/enter”, “backspace”, “insert”, “delete”, “home”, “end”, “page up”, “page down”, “end”, “escape”, “pause”, “break”, “send”, “end”, “txt”, “sym”, and “scroll lock”, among other known functions associated with text entry or telephony entry.
The keys on the physical keyboard 14 that are associated with numbers may be used in both text mode and in telephony (numeric) mode. The keyboard 14 may include a mode selection key, or other hardware or software for switching between text entry (the first user interface) and telephony entry (the second user interface). The telephony characters may be input when the mobile communication device 10 is in telephony or text-entry mode, and the text-entry characters may be input when the mobile communication device 10 is in text-entry mode. The functional keys may also be configured to operate in both the telephony mode and the text-entry mode, or, alternatively, one or more of the functional keys may be operable in only the telephony mode or the text-entry mode. In this manner, the keyboard 14 has at least two distinct ergonomic configurations depending upon the mode of the mobile communication device 10.
In a preferred embodiment, a toggle key is utilized for mode selection between the text-entry and telephony (numeric) modes. Sample toggle keys include the “alt” or “shift” key, where the user selects one of these keys to switch data input from text-entry to telephony mode, or vice versa.
Alternatively, software may be used to determine the mode of entry. If the user is utilizing the telephony application, the default data entry mode will be numbers. If the user is utilizing the text-entry application, such as when composing an email, the default data entry mode will be text. When in each of these modes, the user may switch modes manually by utilizing a toggle key. For example, to enter text in a telephony application, the user selects the “alt” key and then presses the desired alphanumeric key corresponding to the desired letter. Software could also be used to predict whether the user is in telephony or text-entry mode, based upon the keystrokes that are entered by the user.
By providing both a text-entry and a telephony mode, the keyboard design results in at least two distinct, but familiar user interfaces that the user has likely had experience using separately on two distinct devices. In each of the reduced format keyboards 14 discussed herein, the selection of a particular character, number, symbol, or function may be derived from predictive text software residing on the mobile communication device and/or from multiple switches associated with the keys, as discussed in greater detail below.
Referring again to the drawings,
Indicia is positioned on each key to indicate which alphabetic characters, numbers, symbols and functions are associated with each key. In order to differentiate the alphabetic characters and numbers from one another, the font size of the numerical indicia on the keys shown in
Symbols, where not shown, may also be included on the keys shown in the figures. In each of the embodiments shown in
The physical keyboard 14 includes hardware and software associated with each of the keys for entry of a character, as indicated by indicia on or near the key. An example of a mobile communication device having a keyboard assembly with hardware and software associated with key entry is described in U.S. patent application Ser. Nos. 09/967,537 and 10/302,242 and U.S. Pat. No. 6,278,442, the disclosures of which are incorporated herein by reference in their entirety, and depicted in
Referring to
A display 16 is preferably mounted on the PCB 264, as shown in
A speaker 234 is preferably mounted at or near the top of the PCB 264. One or more apertures 235 in the first device housing section 260 are positioned to at least partially expose the speaker 234 when the first and second device housing sections 260, 262 are coupled together. A microphone 236 is mounted in the second device housing section 262. The microphone 236 is at least partially exposed by the aperture 237B in the second device housing section, and coupled to the PCB and other device components. Audio or voice inputs to the microphone 236 may be used, for example, to generate voice communications. When the microphone 236 is positioned in the housing, an aperture (not shown) is provided in the first device housing section 260 to at least partially expose the microphone 236. The microphone 236 may alternatively be mounted in the first device housing section 260 or on the PCB 264.
The device housing sections 260, 262 may include further apertures to expose or partially expose other device components. In the first device housing section 260, apertures 270, 272 and 274 are configured to partially expose the auxiliary I/O devices. An aperture 268 is similarly positioned in the second device housing section 262 to at least partially expose an auxiliary I/O device 228D. An aperture 266 in the second device housing section 262 may be provided to accommodate a power supply such as a battery. Other apertures may also be provided in the device housing as necessary.
Other internal components of the device 10 may also be mounted on the PCB 264. The device components are interconnected to provide at least data and voice communication functionality, possibly in addition to further local non-communication functions and short-range communication functions. Although these other internal components are not shown in
The first and second device housing sections 260, 262, when coupled together, form a handheld mobile communication device housing 10 enclosing the PCB 264 and internal components. The apertures 235, 223, 235 and 237B at least partially expose the speaker 234, display 16, keyboard 14 and microphone 236 as described above. Partial exposure of these components allows a user to make use of these components while at the same time protecting the components from damage. Apertures 268, 270, 272, 274 similarly expose and protect auxiliary I/O devices. When access to a component will normally be required relatively infrequently, a removable cover element may be provided for a corresponding device housing aperture. In the above example of a device power supply, a cover (not shown) is preferably provided for the aperture 266. Access to the power supply is thereby possible when required, yet the battery remains protected when access thereto is not necessary.
The assembly in
The mobile communication device 10 may also include a predictive text computer program that is used in conjunction with the keyboard. Predictive test software is useful in reduced format keyboards, such as the example keyboard, in order to identify the desired input from the combination of keystrokes of a user. A predictive text computer program may, for example, be used to predict a complete word or phrase from one or more keystrokes. If the predictive text computer program does not successfully predict a desired word or phrase, then text-entry characters may be entered more precisely, albeit more slowly, by selecting the appropriate characters on the keys. An example predictive text computer program is described in the following co-owned patent applications, which are incorporated herein by reference in their entirety: “Customizable Predictive Text Method For Reduced Keyboards,” U.S. Provisional Patent Application No. 60/397,680, filed Jul. 23, 2002; “Systems and Methods of Building and Using Custom Word Lists,” International Patent Application No. PCT/CA03/01103, filed Jul. 23, 2003, and “Portable Electronic Device With Keyboard”, International Patent Application No. PCT/CA02/00862, filed Jun. 10, 2002.
A number of different predictive text technologies are known and may be utilized with the example keyboard. In a multi-tap methodology, the user taps a key multiple times until a desired letter, number, symbol, or function is selected. This technology has been utilized on cell phones and touch screen devices, among other devices. Companies that offer solutions for the multi-tap method include Motorola (e.g., iTAP); Zi (e.g., eZiText); AOL (Tegic) (e.g., T9); and Eatoni (e.g., LetterWise). A related method is the long tap method, where a user depresses the key until the desired character appears on the display.
Another technology involves predictive text methodologies. These methodologies utilize database software to predict the entered text. One method involves automatically correcting common spelling mistakes (e.g., “teh” corrected to “the”). Predictive text methodologies use known spellings of words in combination with their probabilities and frequencies of use to determine a preferred word based upon input commands by a user. Disambiguation engines and predictive editor applications may be used to establish a single grammatical or semantic interpretation of the keystrokes entered by a user. With predictive editor applications, the display of the device depicts possible character sequences corresponding to the keystrokes that were entered. Typically, the most commonly used word is displayed first. The user may select other, less common words manually, or otherwise. Other types of predictive text computer programs may be utilized with the keyboard arrangement and keyboard described herein, without limitation.
The handheld mobile communication devices 10, presented in
The housing 12 may be elongated vertically, or may take on other sizes and shapes, including a clamshell housing structure, among other structures. The keyboard may include a mode selection key, or other hardware or software for switching between text entry and telephony entry.
In addition to the processing device 18, other parts of the mobile communication device 10 are shown schematically in
Operating system software executed by the processing device 18 is preferably stored in a persistent store, such as a flash memory 116, but may be stored in other types of memory devices, such as a read only memory (ROM) or similar storage element. In addition, system software, specific device applications, or parts thereof, may be temporarily loaded into a volatile store, such as a random access memory (RAM) 118. Communication signals received by the mobile communication device may also be stored to the RAM 118.
The processing device 18, in addition to its operating system functions, enables execution of software applications 130A-130N on the device 10. A predetermined set of applications that control basic device operations, such as data and voice communications 130A and 130B, may be installed on the device 10 during manufacture. In addition, a personal information manager (PIM) application may be installed during manufacture. The PIM is preferably capable of organizing and managing data items, such as e-mail, calendar events, voice mails, appointments, and task items. The PIM application is also preferably capable of sending and receiving data items via a wireless network 140. Preferably, the PIM data items are seamlessly integrated, synchronized and updated via the wireless network 140 with the device user's corresponding data items stored or associated with a host computer system. An example system and method for accomplishing these steps is disclosed in “System And Method For Pushing Information From A Host System To A Mobile Device Having A Shared Electronic Address,” U.S. Pat. No. 6,219,694, which is owned by the assignee of the present application, and which is incorporated herein by reference.
Communication functions, including data and voice communications, are performed through the communication subsystem 100, and possibly through the short-range communications subsystem. The communication subsystem 100 includes a receiver 150, a transmitter 152, and one or more antennas 154, 156. In addition, the communication subsystem 100 also includes a processing module, such as a digital signal processor (DSP) 158, and local oscillators (LOs) 160. The specific design and implementation of the communication subsystem 100 is dependent upon the communication network in which the mobile communication device 10 is intended to operate. For example, a mobile communication device 10 may include a communication subsystem 100 designed to operate with the Mobitex™, Data TAC™ or General Packet Radio Service (GPRS) mobile data communication networks and also designed to operate with any of a variety of voice communication networks, such as AMPS, TDMA, CDMA, PCS, GSM, etc. Other types of data and voice networks, both separate and integrated, may also be utilized with the mobile communication device 10.
Network access requirements vary depending upon the type of communication system. For example, in the Mobitex and DataTAC networks, mobile devices are registered on the network using a unique personal identification number or PIN associated with each device. In GPRS networks, however, network access is associated with a subscriber or user of a device. A GPRS device therefore requires a subscriber identity module, commonly referred to as a SIM card, in order to operate on a GPRS network.
When required network registration or activation procedures have been completed, the mobile communication device 10 may send and receive communication signals over the communication network 140. Signals received from the communication network 140 by the antenna 154 are routed to the receiver 150, which provides for signal amplification, frequency down conversion, filtering, channel selection, etc., and may also provide analog to digital conversion. Analog-to-digital conversion of the received signal allows the DSP 158 to perform more complex communication functions, such as demodulation and decoding. In a similar manner, signals to be transmitted to the network 140 are processed (e.g. modulated and encoded) by the DSP 158 and are then provided to the transmitter 152 for digital to analog conversion, frequency up conversion, filtering, amplification and transmission to the communication network 140 (or networks) via the antenna 156.
In addition to processing communication signals, the DSP 158 provides for control of the receiver 150 and the transmitter 152. For example, gains applied to communication signals in the receiver 150 and transmitter 152 may be adaptively controlled through automatic gain control algorithms implemented in the DSP 158.
In a data communication mode, a received signal, such as a text message or web page download, is processed by the communication subsystem 100 and is input to the processing device 18. The received signal is then further processed by the processing device 18 for an output to the display 16, or alternatively to some other auxiliary I/O device 106. A device user may also compose data items, such as e-mail messages, using the keyboard 14 and/or some other auxiliary I/O device 106, such as a touchpad, a rocker switch, a thumb-wheel, or some other type of input device. The composed data items may then be transmitted over the communication network 140 via the communication subsystem 100.
In a voice communication mode, overall operation of the device is substantially similar to the data communication mode, except that received signals are output to a speaker 110, and signals for transmission are generated by a microphone 112. Alternative voice or audio I/O subsystems, such as a voice message recording subsystem, may also be implemented on the device 10. In addition, the display 16 may also be utilized in voice communication mode, for example to display the identity of a calling party, the duration of a voice call, or other voice call related information.
The short-range communications subsystem enables communication between the mobile communication device 10 and other proximate systems or devices, which need not necessarily be similar devices. For example, the short-range communications subsystem may include an infrared device and associated circuits and components, or a Bluetooth™ communication module to provide for communication with similarly-enabled systems and devices.
As described above, a preferred example keyboard represents a marriage of a text entry keyboard with a telephony keypad, but in a reduced key format. The example keyboard can be used in two modes. In a first mode, the user utilizes two hands to input text characters, similar to the use of a standard 26 key keyboard. In a second mode, the user utilizes a single hand to input numeric characters in telephony mode. Thus, the example keyboard provides two different methods for input, both of which are already familiar separately to a user.
Accordingly, the example keyboard also concerns a method for operating a keyboard and for inputting text and telephony commands on a keyboard. The method includes inputting numbers into a mobile communication device utilizing a single hand and inputting text into a mobile communication device utilizing two hands. The method further includes inputting functional commands and symbols utilizing two hands. Alternatively, functional commands and symbols may be input utilizing one hand.
The keys may be toggle keys or non-toggle keys, if desired. Additional or fewer rows and columns, above and beyond the number shown herein, may also be provided to position functional and other keys, if desired. Furthermore, the keys may be aligned in columns, or may be staggered, in some embodiments.
While most of the examples depict a QWERTY arrangement of alphabetic characters, the examples are equally applicable to other standard arrangements. Moreover, the QWERTY keyboard has been presented with certain combinations of alphabetic characters on each key. Other combinations may alternatively be utilized, without limitation, as long as the alphabetic characters are presented in the same order as their standard arrangement.
