The present invention relates to hand held mobile devices, and more particularly to a hand held mobile device having a hybrid keypad.
Mobile devices (also referred to as smart phones, handheld devices, handheld computers, PDAs, PDTs, etc.) are widely used worldwide, and may be described as pocket-sized computing devices, typically having a display screen with touch input or a miniature keypad. In some mobile devices the input and output are combined into a touch-screen interface. Mobile devices are popular because they provide the assistance and convenience of a conventional computer (laptop, notebook or otherwise) in environments where carrying one would not be practical. Enterprise digital assistants further extend the available functionality of mobile devices.
An Enterprise digital assistant (EDA) is a handheld computer adapted for usage with SME (Small to Medium Enterprise) and Enterprise business Application software|Applications as a data capture mobile device. Such data capture applications include indicia readers, biometrics, magnetic stripe, smart card and RFID data capture technologies used within communication networks such as WLANs (Wireless Local Area Networks), Bluetooth, Wide area network|WAN/LAN/Personal Area Network|PAN voice and data communications, VOIP and GPRS Edge Communications.
Efforts regarding such systems have led to continuing developments to improve their versatility, practicality and efficiency.
Reference will now be made to exemplary embodiments which are illustrated in the accompanying drawings. Other embodiments may be in various forms and the exemplary embodiments should not be construed as limited to the embodiments set forth herein. Rather, these representative embodiments are described in detail so that this disclosure will be thorough and complete, and will fully convey the scope, structure, operation, functionality, and potential applicability to those skilled in the art. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.
The mobile devices may be operated or utilized in a remote location, such as in an establishment, a store point of transaction (POT), a warehouse, a delivery truck, in the field, etc. Distances for communications from the mobile device may be short (a few meters as in television remote control) or very long (thousands or even millions of kilometers for radio communications). Wireless communication may involve radio frequency communication and may involve point-to-point communication, point-to-multipoint communication, broadcasting, cellular networks and other wireless networks. This may involve: cordless telephony such as DECT (Digital Enhanced Cordless Telecommunications); Cellular systems such as 0G, 1G, 2G, 3G or 4G; Short-range point-to-point communication such as IrDA or RFID (Radio Frequency Identification), Wireless USB, DSRC (Dedicated Short Range Communications); Wireless sensor networks such as ZigBee; Personal area networks such as Bluetooth or Ultra-wideband (UWB from WiMedia Alliance); Wireless computer networks such as Wireless Local Area Networks (WLAN), IEEE 802.11 branded as WiFi or HIPERLAN; or Wireless Metropolitan Area Networks (WMAN) and Broadband Fixed Access (BWA) such as LMDS, WiMAX or HIPERMAN.
Mobile devices may be utilized as part of Mobile Enterprise (Mobile ERP), which is a collection of Online Interactive Business Applications such as SMS and E-mail. Business modules, functions and operations executed using Mobile Enterprise include Collaboration, Document management system (DMS), Customer relationship management (CRM), Point of sale (POS), Human resource management systems (HRMS), Accounting software, Enterprise resource planning (ERP), including sales order, sourcing, tender, request for Quotation, purchase order, shipment, receiving, warehousing, inventory control, delivery order, invoicing, customer service order, production monitoring and control, work order, as well as basic utilities such as corporate calendar, corporate address book, corporate bulletin board, notes and internal messaging.

The mobile device may have a data capture system, such as an indicia reader 150 or RFID module 154 for capturing machine readable data. A human operator may aim a hand-held mobile device having an indicia reader at a target containing an information bearing indicia (IBI) 158 or dataform, text, or other element and actuate a trigger on the mobile device. An IBI or dataform may be an originally machine generated symbology that is also machine readable, such as a 1-D barcode, a 2-D barcode, a 1-D stacked barcode, a logo, glyphs, color-codes, etc.
Other exemplary subsystems or components provided within the housing of a mobile device include a local processor 158, an ASIC 162, local memory 166, a battery 172, a communications module 176 which may communicate via one or more bus 180, data lines or other signal or data communication form. The mobile device may communicate to a local server 116, host processor 184, host memory 188, network 124 or remote server 128.
An exemplary host or local processor may be utilized to perform a number of functional operations, which may involve the performance of a number of related steps, the particulars of which may be determined by or based upon certain configuration settings stored in memory. An exemplary function of a processor may be to decode machine readable information bearing indicia provided within a target or captured image. One dimensional symbologies may include very large to ultra-small, Code 128, Interleaved 2 of 5, Codabar, Code 93, Code 11, Code 39, UPC, EAN, MSI, or other 10 symbologies. Stacked 1D symbologies may include PDF, Code 16K, Code 49, or other stacked 1D symbologies. 2D symbologies may include Aztec, Datamatrix, Maxicode, QR-code, or other 2D symbologies. Decoding is a term used to describe the interpretation of an information bearing indicia captured in an image which has data or information encoded therein.
