||It has been suggested that Mobile Internet device be merged into this article. (Discuss) Proposed since January 2012.|
A mobile device (also known as a handheld computer or simply handheld) is a small, handheld computing device, typically having a display screen with touch input and/or a miniature keyboard and weighing less than 2 pounds (0.91 kg). Nokia, HTC, LG, Motorola Mobility, BlackBerry, and Apple are just a few examples of the many manufacturers that produce these types of devices.
A handheld computing device has an operating system (OS), and can run various types of application software, known as apps. Most handheld devices can also be equipped with Wi-Fi, Bluetooth, and GPS capabilities that can allow connections to the Internet and other Bluetooth-capable devices, such as an automobile or a microphone headset. A camera or media player feature for video or music files can also be typically found on these devices along with a stable battery power source such as a lithium battery.
Early pocket-sized devices were joined in the late 2000s by larger but otherwise similar tablet computers. Much like in a personal digital assistant (PDA), the input and output of modern mobile devices are often combined into a touch-screen interface.
Smartphones and PDAs are popular amongst those who wish to use some of the powers of a conventional computer in environments where carrying one would not be practical. Enterprise digital assistants can further extend the available functionality for the business user by offering integrated data capture devices like barcode, RFID and smart card readers.
Mobile devices have been designed for many applications and include:
- Mobile computers
- Digital still camera (DSC)
- Digital video camera (DVC or digital camcorder)
- Mobile phone
- Personal navigation device (PND)
Handheld devices have become ruggedized for use in mobile field management. Uses include digitizing notes, sending and receiving invoices, asset management, recording signatures, managing parts, and scanning barcodes.
Recent developments in mobile collaboration systems employ handheld devices that combine video, audio and on-screen drawing capabilities to enable multi-party conferencing in real-time, independent of location.
Users can watch television through Internet on mobile devices. Mobile television receivers have existed since the 1960s, and in the 21st century mobile phone providers began making television available on cellular phones.
Nowadays, mobile devices can create, sync, and share everything we want despite of distance or specifications of mobile devices. In medical field, mobile devices are quickly becoming essential tools for accessing clinical information such as drugs, treatment, even medical calculation. Recently, some medical related applications (app) are free to download. However, particularly among medical students, they will approach the occasion where the prompt mobile searching is required. Especially in hospitals, they had dead spots in cellular network coverage which results slow loading times, intermittent internet connections and inability to access needed information.
In military field, mobile devices have created new opportunities for the Army to deliver training and education materials to soldiers around the world. Casey said that future education of army and beyond industry will be discussed within army and Helen Remily, director of the training manager mentioned that future training and education will be based on mobile devices, e-books and games for simulations.
