As mobile devices become ubiquitous, there will be a proliferation of services which include the use of the cloud. Flexible applications include video chat, Web browsing, payment systems, near field communication, audio recording etc. What makes the mobile device unique compared to other technologies is the inherent flexibility in the hardware and also software. 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 from the Internet. Wireless access devices can be static and mobile users can move in between wired and wireless hotspots such as in Internet cafés. Not all network access by mobile users, applications and devices need 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 nanometres through micrometres 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 centimetre-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. Accompanied 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: accompanied, surface-mounted, or embedded into the fabric of a host, e.g., an embedded controller in a host device. 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.
