![]() Not all network access by mobile users, applications, and devices needs to be via wireless networks and vice versa. Also, see smart device.Īlthough mobility is often regarded as synonymous with having wireless connectivity, these terms are different. These can be formed into more flexible non-planar display surfaces and products such as clothes and curtains, see OLED display. Skin: fabrics based upon light emitting and conductive polymers and organic computer devices. Dust refers to miniaturized devices without direct HCI interfaces, e.g., micro-electro-mechanical systems ( MEMS), ranging from nanometers through micrometers to millimeters. 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. smartphones, phablets and pads are defined as hand-held decimeter-sized devices. Mark Weiser, known as the father of ubiquitous computing, referred to device sizes that are tab-sized, pad, and board sized, where tabs are defined as accompanied or wearable centimeter-sized devices, e.g. The most common size of a mobile computing device is pocket-sized, but other sizes for mobile devices exist. Hence, mobile hosts with embedded devices such as an autonomous vehicle can appear larger than pocket-sized. embedded into the fabric of a host, e.g., an embedded controller in a host device.Īccompanied refers to an object being loosely bound and accompanying a mobile host, e.g., a smartphone can be carried in a bag or pocket but can easily be misplaced.There are three basic ways mobile devices can be physically bound to mobile hosts: Another example is an autonomous vehicle. An example of a true mobile computing device, where the device itself is mobile, is a robot. It is the host that is mobile, i.e., a mobile human host carries a non-mobile smartphone device. Strictly speaking, many so-called mobile devices are not mobile. What kind of host devices it can be bound with.Whether the device is mobile or some kind of host to which it is attached is mobile.Major global manufacturers of mobile devices are Apple, Samsung, Huawei, Meizu, Zte, Xiaomi, Sony, Google, HTC, LG, TCL, Motorola Mobility, Nokia, Realme and Micromax Informatics.ĭevice mobility can be viewed in the context of several qualities: ![]() Mobile devices may provide biometric user authentication, such as face recognition or fingerprint recognition. Enterprise digital assistants can provide additional business functionality such as, integrated data capture via barcode, RFID, and smart card readers.īy 2010, mobile devices often contained sensors such as accelerometers, magnetometers and gyroscopes, allowing the detection of orientation and motion. Phones/tablets and personal digital assistants may provide much of the functionality of a laptop/ desktop computer in addition to exclusive features. Input and output are usually via a touch-screen interface. Mobile devices may run mobile operating systems that allow third-party applications to be installed and run.Įarly smartphones were joined in the late 2000s by larger tablets. Power is typically provided by a lithium-ion battery. Integrated cameras, the ability to place and receive voice and video telephone calls, video games, and Global Positioning System (GPS) capabilities are common. Many mobile devices can connect to the Internet and connect with other devices, such as car entertainment systems or headsets, via Wi-Fi, Bluetooth, cellular networks, or near-field communication. Mobile devices typically have a flat LCD or OLED screen, a touchscreen interface, and digital or physical buttons.
