A mobile device (or handheld computer) is a small enough to hold and operate in the hand. Typically, any handheld computer device will have an interface, providing a interface with digital buttons and keyboard or physical buttons along with a physical keyboard. Many such devices can connect to the and interconnect with other devices such as car entertainment systems or headsets via , , or near field communication (NFC). Integrated cameras, digital media players, the ability to place and receive calls, , and Global Positioning System (GPS) capabilities are common. Power is typically provided by a . Mobile devices may run mobile operating systems that allow third-party to be installed and run.

Early were joined in the late 2000s by larger, but otherwise the same, . Input and output is now usually via a touch-screen interface. / and personal digital assistants may provide much of the functionality of a laptop or desktop computer but more conveniently. Enterprise digital assistants can provide additional business functionality such as integrated data capture via , and readers. By 2010, mobile devices often contained sensors such as , and allowing detection of orientation and motion. Mobile devices may provide user authentication such as or fingerprint recognition.

Manufacturers include Apple, Samsung, , , , Google, Microsoft and Motorola Mobility.

Mobile device may also be a term used to refer exclusively to a or .

If the device is a /, the external hardware design will have a providing a and buttons (icons) on-screen, and will include physical sound volume buttons and sometimes a home button. It will also include a and . It will usually include front and rear-facing cameras, along with a microphone.


Characteristics
Device mobility can be viewed in the context of several dimensions:

.
  • Physical dimensions and weight
  • Whether or not the device is mobile or some kind of host to which it is attached to is mobile
  • What kind of host devices can be bound to
  • How devices are attached to a host
  • When the mobility occurs

Strictly speaking, many so-called mobile devices are not mobile. It is the host that is mobile, i.e., a mobile human host carries a non-mobile smart phone device. An example of a true mobile computing device, where the device itself is mobile, is a . Another example is an autonomous vehicle. There are three basic ways mobile devices can be physically bound to mobile hosts: accompanied, surface-mounted or embedded into the fabric of a host, e.g., an embedded controller embedded in a host device. Accompanied refers to an object being loosely bound and accompanying a mobile host, e.g., a mobile phone can be carried in a bag or pocket but can easily be misplaced. Hence, mobile hosts with embedded devices such as an autonomous vehicle can appear larger than pocket-sized.

As stated earlier, the most common size of mobile computing device is pocket-sized that can be hand-held, but other sizes for mobile devices exist too. , known as the father of ubiquitous computing, computing everywhere, referred to device sizes that are tab-sized, pad and board sized, where tabs are defined as accompanied or wearable centimetre-sized devices, e.g. and , and pads are defined as hand-held decimetre-sized devices, e.g., laptops and tablet computers. If one changes the form of the mobile devices in terms of being non-planar, one can also have skin devices and tiny dust-sized devices. Dust refers to miniaturised devices without direct HCI interfaces, e.g., micro electro-mechanical systems (MEMS), ranging from nanometres through micrometers to millimetres. See also . Skin: fabrics based upon light emitting and conductive polymers and organic computer devices. These can be formed into more flexible non-planar display surfaces and products such as clothes and curtains, see . See also .

Although mobility is often regarded as synonymous with having wireless connectivity, these terms are different. Not all network access by mobile users, applications and devices need be via wireless networks and vice versa. Wireless access devices can be static and mobile users can move in between wired and wireless hotspots such as in Internet cafés. Some mobile devices can be used as mobile Internet devices to access the Internet while moving but they do not need to do this and many phone functions or applications are still operational even while disconnected to the . What makes the mobile device unique compared to other technologies is the inherent flexibility in the hardware and also the software. Flexible applications include video chat, Web browsing, payment systems, NFC, audio recording etc. As mobile devices become ubiquitous there, will be a proliferation of services which include the use of the . Although a common form of mobile device, a smartphone, has a display, another perhaps even more common form of smart computing device, the , e.g., used as a bank card or travel card, does not have a display. This mobile device often has a CPU and memory but needs to connect, or be inserted into a reader in order to display its internal data or state.


Types
Mobile devices have been designed for many applications. They include:
    • Mobile Internet devices
    • /
    • Wearable computers
      • Head-mounted displays
    • Personal digital assistants
    • Enterprise digital assistants
    • Graphing calculators
    • Handheld game consoles
    • Portable media players
    • Digital media player
  • Digital still cameras (DSC)
  • Digital video cameras (DVC) or digital
  • Personal navigation devices (PND)


Uses
Handheld devices have become for use in mobile field management. Uses include notes, sending and receiving , asset management, recording signatures, managing parts, and . In 2009, developments in mobile collaboration systems enabled the use of handheld devices that combine video, audio and on-screen drawing capabilities to enable multi-party in real-time, independent of location. Handheld computers are available in a variety of form factors, including on the low end, handheld , and (, ).Mellow, P. (2005).The media generation: Maximise learning by getting mobile. In Ascilite, 470–476 Users can watch television through Internet by IPTV on some 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.Lotz, Amanda D. (2007).

In the 2010s, mobile devices can , and share many data despite the distance or specifications of said devices. In the medical field, mobile devices are quickly becoming essential tools for accessing clinical information such as drugs, treatment, even medical calculation. Due to the popularity of mobile gaming , the Gambling industry started offering casino games on mobile devices. Which in turn lead to inclusion of these devices in anti hazard legasliture as devices that could potentially be used in illegal gambling. Other potentially illegal activities might include the use of mobile devices in distributing child pornography and the legal sex industry use of mobile apps and hardware to promote its activities, as well as the posibility of using mobile devices to perform trans border services, which are all issues that need to be regulated, In the military, mobile devices have created new opportunities for the armed forces to deliver training and educational materials to soldiers, regardless of where they are stationed.
