Hipster PDA

The Hipster PDA is a paper-based personal organizer, popularized two years after appearing on an Aqua Teen Hunger Force episode, by San Francisco writer Merlin Mann. Originally a tongue-in-cheek reaction to the increasing expense and complexity of personal digital assistants, the Hipster PDA (said to stand for 'Parietal Disgorgement Aid') simply comprises a sheaf of index cards held together with a binder clip. Following widespread coverage in the media and blogs, the Hipster PDA (abbreviated 'hPDA') has become a popular personal management tool particularly with followers of David Allen's Getting Things Done methodology and users of the Fisher Space Pen.
Advocates of the hPDA claim that it is a cheap, lightweight, free-form organizer that doesn't need batteries and is unlikely to be stolen. Critics cite the lack of integration with desktop PC productivity software and point out that there is no easy way to back up the often critical information stored in an hPDA.
Although it began as a joke, or perhaps a statement about technology fetishism, the Hipster PDA has rapidly gained a population of serious users, with hundreds posting pictures of their customized hPDAs on photo sharing sites and exchanging tips on Internet mailing lists. Enthusiasts also design and share index card-size printable templates for storing contacts, to-do lists, calendars, notes, project plans, and so on.
A Hipster Nano PDA utilizes business cards (often given superfluously at trade shows) with blank backs and one that has a calendar on the back.

PDA (Personal digital assistant)

A Personal digital assistant (PDA) is a handheld computer, but has become much more versatile over the years. PDAs are also known as small computers or palmtop computers. PDAs have many uses: calculation, use as a clock and calendar, accessing the Internet, sending and receiving E-mails, video recording, typewriting and word processing, use as an address book, making and writing on spreadsheets, scanning bar codes, use as a radio or stereo, playing computer games, recording survey responses, and Global Positioning System (GPS). Newer PDAs also have both color screens and audio capabilities, enabling them to be used as mobile phones (smartphones), web browsers, or portable media players. Many PDAs can access the Internet, intranets or extranets via Wi-Fi, or Wireless Wide-Area Networks (WWANs). Many PDAs employ touch screen technology.

Touch screen

Many original PDAs, such as the Apple Newton and the Palm Pilot, featured touch screens for user interaction, having only a few buttons usually reserved for shortcuts to often used programs. Touch screen PDAs, including Windows Pocket PC devices, usually have a detachable stylus that can be used on the touch screen. Interaction is then done by tapping the screen to activate buttons or menu choices, and dragging the stylus to, for example, highlight. Text input is usually done in one of four ways:

• Using a virtual keyboard, where a keyboard is shown on the touch screen. Input is done by tapping letters on the screen.
• Using external keyboard or chorded keyboard connected by USB or Bluetooth.
• Using letter or word recognition, where letters or words are written on the touch screen, and then "translated" to letters in the currently activated text field. Despite rigorous research and development projects, end-users experience mixed results with this input method, with some finding it frustrating and inaccurate, while others are satisfied with the quality.^[1] Recognition and computation of handwritten horizontal and vertical formulas such as "1 + 2 =" was also under development.
• Stroke recognition (termed Graffiti by Palm). In this system a predefined set of strokes are defined to represent the various characters needed. The user learns to draw these strokes on the screen or in an input area. The strokes are often simplified character shapes to make them easier to remember.

PDAs for business use, including the BlackBerry and Treo, have full keyboards and scroll wheels or thumb wheels to facilitate data entry and navigation, in addition to supporting touch-screen input. There are also full-size foldable keyboards available that plug directly, or use wireless technology to interface with the PDA and allow for normal typing. BlackBerry also has additional functionality as push based email and applications.

Newer PDAs, such as the Apple iPhone and iPod touch include new user interfaces using other means of input. The iPhone and iPod touch uses a technology called Multi-touch.

Memory cards

Although many early PDAs did not have memory card slots, now most have either an SD (Secure Digital) and/or a Compact Flash slot. Although originally designed for memory, SDIO and Compact Flash cards are available for such things as Wi-Fi and Webcams. Some PDAs also have a USB port, mainly for USB flash drives.

As more PDAs include telephone support, to keep the size down, many now offer miniSD or microSD slots instead of full-sized SD slots.

Wired connectivity

While many earlier PDAs connected via serial ports or other proprietary format, many today connect via USB cable. This served primarily to connect to a computer, and few, if any PDAs were able to connect to each other out of the box using cables, as USB requires one machine to act as a host - functionality which was not often planned. Some PDAs were able to connect to the internet, either by means of one of these cables, or by using an extension card with an ethernet port/RJ-45 adaptor.

Wireless connectivity

Most modern PDAs have Bluetooth wireless connectivity, an increasingly popular tool for mobile devices. It can be used to connect keyboards, headsets, GPS and many other accessories, as well as sending files between PDAs. Many mid-range and superior PDAs have Wi-Fi/WLAN/802.11-connectivity, used for connecting to Wi-Fi hotspots or wireless networks. Older PDAs predominantly have an IrDA (infrared) port; however fewer current models have the technology, as it is slowly being phased out due to support for Bluetooth and Wi-Fi. IrDA allows communication between two PDAs: a PDA and any device with an IrDA port or adapter. Most universal PDA keyboards use infrared technology because many older PDAs have it, and infrared technology is low-cost and has the advantage of being permitted aboard aircraft.

Synchronization

An important function of PDAs is synchronizing data with a PC. This allows up-to-date contact information stored on software such as Microsoft Outlook or ACT! to update the database on the PDA. The data synchronization ensures that the PDA has an accurate list of contacts, appointments and e-mail, allowing users to access the same information on the PDA as the host computer.

The synchronizing also prevents the loss of information stored on the device in case it is lost, stolen, or destroyed. Another advantage is that data input is usually a lot quicker on a PC, since text input via a touch screen is still not quite optimal. Transferring data to a PDA via the computer is therefore a lot quicker than having to manually input all data on the handheld device.

Most PDAs come with the ability to synchronize to a PC. This is done through synchronization software provided with the handheld, such as HotSync Manager, which comes with Palm OS handhelds, Microsoft ActiveSync for older versions of Windows or Windows Mobile Device Center on Windows Vista, which comes with Windows Mobile handhelds.

These programs allow the PDA to be synchronized with a Personal information manager. This personal information manager may be an outside program or a proprietary program. For example, the BlackBerry PDA comes with the Desktop Manager program which can synchronize to both Microsoft Outlook and ACT!. Other PDAs come only with their own proprietary software. For example, some early Palm OS PDAs came only with Palm Desktop while later Palms such as the Treo 650 has the built-in ability to sync to Palm Desktop and/or Microsoft Outlook, while Microsoft's ActiveSync and Windows Mobile Device Center only synchronize with Microsoft Outlook or a Microsoft Exchange server.

Third-party synchronization software is also available for many PDAs from companies like Intellisync and CompanionLink. This software synchronizes these handhelds to other personal information managers which are not supported by the PDA manufacturers, such as GoldMine and Lotus Notes.

Customization

As with personal computers, it is possible to install additional software on most PDAs. Software can be bought or downloaded from the Internet, allowing users to personalize their PDAs to their liking. An example of this would be the display theme for the PDA. Almost all PDAs also allow for adding some form of hardware. The most common is a memory card slot, which allows the users to get additional and exchangeable storage space on their handheld devices. There are also miniature keyboards that can be connected to most mainstream PDAs for quicker text input. PDAs with Bluetooth use Bluetooth-enabled devices like headsets, mice and (possibly foldable) keyboards.

Uses

PDAs are used to store information that can be accessed at any time and any where.

Automobile navigation

Many PDAs are used in car kits and are fitted with differential Global Positioning System (GPS) receivers to provide realtime automobile navigation. PDAs are increasingly being fitted as standard on new cars.

Many systems can also display traffic conditions, dynamic routing and roadside mobile radar guns. Popular software in Europe and in America for this functionality are TomTom, Garmin, iGO etc. showing road conditions and 2D or 3D environments.

Ruggedized PDAs

For many years businesses and government organizations have relied upon rugged PDAs for mobile data applications. Typical applications include supply chain management in warehouses, package delivery, route accounting, medical treatment and record keeping in hospitals, facilities maintenance and management, parking enforcement, access control and security, capital asset maintenance, meter reading by utilities, and "wireless waitress" applications in restaurants and hospitality venues.
