Uses of PDA
PDAs are used to store information that can be accessed at any time and anywhere.
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 also known as enterprise digital assistants (EDAs) 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. A common feature of EDAs are the integration of Data Capture devices like Bar Code, RFID and Smart Card Readers.
Medical and scientific uses
In medicine, PDAs have been shown to aid diagnosis and drug selection and some studies have concluded that their use by patients to record symptoms improves the effectiveness of communication with hospitals during follow-up. A range of resources have been developed to cater for the demand from the medical profession which supply drug databases, treatment information and relevant news in formats specific to mobile devices and services such as AvantGo translate medical journals into readable formats and provide updates from journals. WardWatch organizes medical records to remind doctors making ward rounds of information such as the treatment regimens of patients and programs. Finally, Pendragon and Syware provide tools for conducting research with mobile devices, and connecting to a central server allowing the user to enter data into a centralized database using their PDA. Additionally, Microsoft Visual Studio and Sun Java provide programming tools for developing survey instruments on the handheld. These development tools allow for integration with SQL databases that are stored on the handheld and can be synchronized with a desktop/server based database.
Recently the development of Sensor Web technology has led to discussion of using wearable bodily sensors to monitor ongoing conditions like diabetes and epilepsy and alerting medical staff or the patient themselves to the treatment required via communication between the web and PDAs.
Educational uses
As mobile technology has become very common, it is no surprise that personal computing has become a vital learning tool by this time. Educational institutes have commenced a trend of integrating PDAs into their teaching practices (mobile learning). With the capabilities of PDAs, teachers are now able to provide a collaborative learning experience for their students. They are also preparing their students for possible practical uses of mobile computing upon their graduation.
PDAs and handheld devices have recently been allowed for digital note taking. This has increased student’s productivity by allowing individuals to quickly spell-check, modify, and amend their class notes or e-notes. Educators are currently able to distribute course material through the use of the internet connectivity or infrared file sharing functions of the PDA. With concerns to class material, textbook publishers have begun to release e-books, or electronic textbooks, which can be uploaded directly to a PDA. This then lessens the effort of carrying multiple textbooks at one time.
To meet the instructive needs sought by educational institutes, software companies have developed programs with the learning aspects in mind. Simple programs such as dictionaries, thesauri, and word processing software are important to the digital note taking process. In addition to these simple programs, encyclopedias and digital planning lessons have created added functionality for users.
With the increase in mobility of PDAs, school boards and educational institutes have now encountered issues with these devices. School boards are now concerned with students utilizing the internet connectivity to share test answers or to gossip during class time, which creates disruptions. Many school boards have modernized their computer policies to address these new concerns. Software companies such as Scantron Corp. have now created a program for distributing digital quizzes. The quiz software disables the infrared function on PDAs, which eliminates the element of information sharing among individuals during the examination. Many colleges encourage the use of PDAs, and some business, nursing, and physician assistant (PA) programs even require them.
Sporting uses
PDAs are used by glider pilots for pre-flight planning and to assist navigation in cross-country competitions. They are linked to a GPS to produce moving-map displays showing the tracks to turn-points, airspace hazards and other tactical information.
PDAs may also be used by music enthusiasts. They can be used to play a variety of file formats (unlike most MP3 Players) during physical exercise (e.g. running), unlike certain larger devices such as laptops.
PDAs can be used by road rally enthusiasts. PDA software can be used for calculating distance, speed, time, and GPS navigation as well as unassisted navigation.
PDA for people with disabilities
PDAs offer varying degrees of accessibility for people with differing abilities, based on the particular device and service. People with vision, hearing, mobility, and speech impairments may be able to use PDAs on a limited basis, and this may be enhanced by the addition of accessibility software (e.g. speech recognition for verbal input instead of manual input). Universal design is relevant to PDAs as well as other technology, and a viable solution for many user-access issues, though it has yet to be consistently integrated into the design of popular consumer PDA devices.
PDAs have recently become quite useful in the Traumatic Brain Injury/Posttraumatic Stress Disorder population, especially seen in troops returning home from Operation Iraqi Freedom(OIF)/Operation Enduring Freedom(OEF). PDAs address memory issues and help these men and women out with daily life organization and reminders. As of quite recently, the Department of Veterans' Affairs (VA) has begun issuing thousands of PDAs to troops who present the need for them. Occupational therapists have taken on a crucial role within this population helping these veterans return to the normalcy of life they once had.
