The aim of wearable computing community is to develop new user interfaces that mediate (augment, deliberately diminish, or otherwise modify) non-computer activities, without interfering with the user's everyday tasks. The design of wearable computers is still a topic of research, and a variety of user interfaces are being proposed.
The commercialization of wearable computing has been led by companies such as Xybernaut , HandyKey , and ViA . Publicly-traded Xybernaut has forged alliances with companies such as IBM and Sony in order to make wearable computing widely available. In 1998 Seiko marketed the Ruputer, a computer in a (fairly large) wristwatch, to mediocre returns. In 2001 IBM developed and publically displayed two prototypes for a wristwatch computer running Linux, but the product never came to market. In 2002 Fossil announced the Fossil WristPDA, which ran the PalmOS. Its release date was set for summer of 2003, but was delayed several times and eventually pushed back indefinitely.
Some wearable computers use keyerslightvector paintings. Note the thumbwheel for cursor control and lightvector weight setting. The keyer is designed to hold a video screen (below the keyer) and a photographic flash lamp (above the keyer). A keyer is a device for signalling by hand, by wa (keyswitches mounted to a grip, rather than to a board, as with a keyboard) and trackballs as input devices, but many try to use more intuitive means of input like gesture , speech recognitionSpeech recognition technologies allow computers equipped with a source of sound input, such as a microphone, to interpret human speech, e. for transcription or as an alternative method of interacting with a computer. Classification Such systems can be cla or context awarenessContext awareness is a term from computer science, that is used for devices that have information about the circumstances under which they operate and can react accordingly. Context aware devices may also try to make assumptions about the user's current s. The output may be presented through displays, lights, sound or even hapticHaptic means pertaining to the technology of touch. It is an emerging technology that promises to have wide reaching implications. History One of the earliest forms of haptic devices is used in large modern aircraft that use servo systems to operate contr interfaces. Some mediated reality ( augmentedAugmented reality (AR) is a field of computer research which deals with the combination of real world and computer generated data. At present, most AR research is concerned with the use of live video imagery which is digitally processed and "augmented" by, diminished, or otherwise modified reality) systems can also be considered wearable computers.
Wearable computers of the 1970s were typically large, sometimes even requiring the user to wear a backpack. In the 1980s these systems were miniaturized to smart clothes (computer jackets) and eyeglasses, where the components were mounted outside the eyeglasses. In the 1990s covert or normal-looking systems were developed that had the appearance of ordinary clothing and eyeglasses, by way of an underwearable computer (worn under a shirt) and EyeTap eyeglasses. In 1998, a fully functional wristwatch computer system was designed and built, and later featured on the cover of Linux Journal.
Steve MannSteve Mann (born 1962) is a professor at the University of Toronto, an advocate, and arguably the founder of the field of wearable computing based on his early work in personal imaging. Now Magazine, The Globe and Mail, National Post, and Toronto Life hav's wearcomp has other properties such as operational constancy (the property that the computer is always on and ready for use).The United States ArmyThe Army is the branch of the United States armed forces which has primary responsibility for land-based military operations. As of fiscal year 2002 (FY02), it consisted of 480,000 soldiers on active duty and 555,000 in reserve (350,000 in Army National G plans to issue 10,000 wearable computers to its combat troops in the next few years. They have approved a robust design that will supposedly be immune to weather, temperature, and vibration extremes. It consists of two belt-hung modules for power and processing, and an interface integrated with the regular combat helmet.
