====WearComp====
 +
In 1981, while still in high school, Steve Mann designed backpack-mounted computer to control photographic equipment<ref> Rhodes, Bradley. A Brief History of Wearable Computing. http://www.media.mit.edu/wearables/lizzy/timeline.html#1981b</ref>. Mann felt that humans that computers and computing environments should be available anywhere to a person, not just at a specifically designed computer terminal. While enrolled in classes at MIT, Mann wore many pounds of computing equipment almost everywhere he went. As time progressed, computing became lighter, and Steve Mann’s load became less burdensome while still retaining the same functionality. In December 1994, Steve Mann developed the "Wearable Wireless Webcam." Webcam transmitted images point-to-point from a head-mounted analog camera to an SGI base station via amateur TV frequencies. The images were processed by the base station and displayed on a webpage in near real-time.<ref>Kieffner, Tara. Wearable Computers: An Overview.

====Operational modes of wearable computing====
+
Steve Mann envisioned a future in which hardware could be downloaded in as easily as software. Where one’s contact lens prescription could change during the day based on one’s needs. A future where a device morphs is the most fluid and liquid that an interface can become. Interfaces today are limited by their external structure. This limitation will dissolve when the hardware dissolves. Computers have diminished in volume from gymnasiums to desktops to pockets, and computer screens have become liquid, allowing buttons to appear anywhere they are needed. Although the Internet is invisible and seemingly omnipresent, it is only accessible by two-dimensional interfaces on physical machines in connected fields.

[[Steve Mann]] identifies three operational modes in the interaction between human and computer:

"Unlike other wearable devices (wristwatches, regular eyeglasses, wearable radios, etc.), a WearComp is as reconfigurable as the familiar desktop or mainframe computer.

=====Constancy=====
+
====Active Badge====
−
The computer runs continuously, and is always ready to interact with the user. Unlike a hand-held device, laptop computer, or PDA, it does not need to be opened up and turned on prior to use. The signal flow from human to computer, and computer to human runs continuously to provide a constant user interface.
+
In 1990 Italian computer manufacturer Olivetti developed an active badge system<ref>http://www.media.mit.edu/wearables/lizzy/timeline.html#1990b</ref>. The badges were worn around the neck and operated only in specially-wired buildings, where each room and door has an infra-red tranceiver to communicate with the badge.<ref>Greaves, David. Olivetti Research Active Badge. 2000. http://koo.corpus.cam.ac.uk/projects/badges/index.html</ref> The Active Badge used using infrared signals to communicate a person's location: Olivetti developed a name badge that transmitted a unique id to IR receivers placed in rooms around a building. This allowed these "smart rooms" to track a person's location and log it in a central database.

=====Augmentation=====
+
Much of what was possible with early wearable computing is now possible with mobile phones. David Greaves wore an Active Badge at Cambridge University to unlock the buildings where he worked and to give out his location.<ref>Ibid.</ref>. Although the Active Badge was useful, Greaves mentioned his colleagues "stopped wearing their badges in the office environment once they had a mobile phone".<ref>Ibid.</ref>

Traditional computing paradigms are based on the notion that computing is the primary task. Wearable computing, however, is based on the notion that computing is NOT the primary task. The assumption of wearable computing is that the user will be doing something else at the same time as doing the computing. Thus the computer should serve to augment the intellect, or augment the senses.

=====Mediation=====

===Guidelines for Wearable Computing===
−
Unlike hand held devices, laptop computers, and PDAs, the wearable computer can encapsulate us (Fig. 1c). It doesn't necessarily need to completely enclose us, but the concept allows for a greater degree of encapsulation than traditional portable computers. There are two aspects to this encapsulation:

===Operational Modes of Wearable Computing===

It can function as an information filter, and allow us to block out material we might not wish to experience, whether it be offensive advertising, or simply a desire to replace existing media with different media. In less severe manifestations, it may simply allow us to alter our perception of reality in a very mild sort of way.

Mann defined three operational modes in this new interaction between human and computer, and six informational flow paths.<ref>Mann, Steve. Definition of "Wearable Computer".

For further reading, see the references section of this entry. It is recommended that anyone working on wearable computing read Mann's work on the Eyetap and follow the full set of guidelines for wearable computing.

=====Privacy=====
+
<blockquote>
−
Mediation allows us to block or modify information leaving our encapsulated space. In the same way that ordinary clothing prevents others from seeing our naked bodies, the wearable computer may, for example, serve as an intermediary for interacting with untrusted systems, such as third party digital anonymous cash "cyberwallets". In the same way that some martial artists, especially kendoka, wear a long robe that comes right down to the ground, in order to hide the placement of their feet from their oponent, wearable computing can also be used to clothe our otherwise transparent movements in cyberspace. Although other technologies, like desktop computers, can help us protect our privacy with programs like Pretty Good Privacy (PGP), the Achilles' heel of these systems is the space between us and them. It is generally far easier for an attacker to compromise the link between us and the computer (perhaps through a so-called trojan horse or other planted virus) than it is to compromise the link between our computer and other computers. Thus wearable computing can be used to create a new level of personal privacy because it can be made much more personal; if it is always worn, except perhaps during showering, it is less likely to fall prey to covert attacks upon the hardware itself. Moreover, the close synergy between the human and computers makes it harder to attack directly, e.g. as one might peek over a person's shoulder while they are typing, or hide a video camera in the ceiling above their keyboard. Furthermore, the wearable computer can take the form of undergarments that are encapsulated in an outer covering or outerwear of fine conductive fabric to protect from an attacker looking at radio frequency emissions. The actual communications between the wearer and other computers (and thus other people) can be done by way of outer garments, which contain conformal antennas, or the like, and convey an encrypted bitstream.

Because of its ability to encapsulate us, e.g. in embodiments of wearable computing that are actually articles of clothing in direct contact with our flesh, WearComp may also be able to make measurements of various physiological quantities. Thus the signal flow depicted in Fig 1a is also enhanced by the encapsulation as depicted in Fig 1c. To make this signal flow more explicit, Fig 1c has been redrawn: in Fig 1d, the computer and human are depicted as two separate entities within an optional protective shell, which may be removed or partially removed if a mixture of augmented and mediated interaction is desired.

===Future of Wearable Computing===
 +
The best wearable computers will evaporate over time until they are no longer noticeable or are proper ubiquitous extensions of the self, as valuable and as iconic as sports cars and external transport structures for the physical body. Their interfaces will be invisible. All that is solid will melt into air.

=====Unmonopolizing of the user's attention=====
+
[[Category:Book Pages]]
−
(The Wearable Computer) does not cut you off from the outside world like a virtual reality game or the like. You can attend to other matters while using the apparatus. It is built with the assumption that computing will be a secondary activity, rather than a primary focus of attention. In fact, ideally, it will provide enhanced sensory capabilities. It may, however, mediate (augment, alter, or deliberately diminish) the sensory capabilities.
+
[[Category:Finished]]
−
 
+
[[Category:Illustrated V2]]
−
=====Unrestrictive to the user=====
+
−
Is ambulatory, mobile, roving; "you can do other things while using it". E.g. you can type while jogging, etc.
+
−
 
+
−
=====Observable by the user=====
+
−
Can get your attention continuously if you want it to; within reasonable limits (e.g. that you might not see the screen while you blink or look away momentarily) the output medium is constantly perceptible by the wearer.
+
−
 
+
−
=====Controllable by the user=====
+
−
 
+
−
=====Responsive=====
+
−
One can grab control of it at any time you wish. Even in automated processes you can manually override To break open and enter the control loop at any time (e.g. a big HALT button, for use when an application mindlessly opens all 50 documents that were highlighted when you accidently pressed Enter, would make a computer more controllable).
+
−
Infinitely-often-controllable: the constancy of user interface results from almost-always observability and infinitely-often controllability in the sense that there is always a potential for manual override which need not be always exercised.
+
−
Attentive to the environment: it is environmentally aware, multimodal, multisensory. (this ultimately increases the user's situational awareness).
+
−
 
+
−
=====Communicative to others=====
+
−
Can be used as a communications medium when you want it to.
+
−
 
+
−
=====Expressive=====
+
−
Allows the wearer to be expressive through the medium, whether as a direct communications medium to others, or as means of assisting the production of expressive media (artistic or otherwise).
+
−
Implied by the above six properties is that it must also be:
+
−
 
+
−
=====Constant=====
+
−
Always on, running, and ready. May have "sleep modes" but is never "dead" (unlike a laptop computer, which must be opened up, switched on, and booted up before use).
+
−
=====Personal: human and computer are inextricably intertwined.
+
−
 
+
−
=====Prosthetic=====
+
−
You can adapt to it so that it acts as a true extension of mind and body; after time you forget that you are wearing it.
+
−
 
+
−
=====Assertive=====
+
−
Resists, if you wish, prohibition or requests by others for removal. This is in contrast to a laptop, in briefcase or bag, that could be separated from you by the "please leave all bags and briefcases at the counter" policy of a department store, library, or similar establishment.
+
−
 
+
−
=====Private=====
+
−
Others can't observe or control it unless you let them. Others can't determine system status unless you want them to, e.g. the clerk at the refund counter in a department store where photography is prohibited can't tell whether or not you are transmitting wireless video to a spouse for remote advice, in contrast to camcorder technology where it is obvious you are taking a picture when you hold the camcorder up to your eye.
+
−
Note that a computer mediation device with sufficient bandwidth can synthesize or even heighten the augmentational aspects. For example a sufficiently attentive computer can sustain a sufficient illusion of being unmonopolizing that it could encapsulate the user and still provide the same experience as system running in the augmentational mode of operation. Similarly, a sufficiently communicative machine, especially if "machine" is broadened to include mechanical mediation devices such as motorized exoskeletons, can synthesize the unrestrictive attribute.

===Modern Wearable Computing===
+
−
Although the Internet is invisible and seemingly omnipresent, it is only accessible by two-dimensional interfaces on physical machines in connected fields. It has only been a recent occurrence that we’ve been able to carry around complex computational interfaces in our pockets, increasing technological capabilities into our everyday lives. Until this point, one had to be in a certain time and place in order to access computing power. This usually meant a college or university, and sometimes between the hours of 3 and 6 Am.

The first person to pioneer the idea of being able to compute anywhere and be connected was Steven Mann, the inventor of Wearable computing. He thought that humans should not contort to computers, but that computers should contort to humans. He wore 80 pounds of computing equipment, including a wireless uplink to an early manifestation of the Internet (MITs local Internet) starting in 1979. As time progressed, computing became lighter, and Steve Mann’s load became less burdensome while still retaining the same functionality.

This transformation allows it to be worn constantly, with the goal of becoming a seamless extension of the body and mind.

+
−
 
+
−
=====Definition=====
+
−
EyeTap is a device which allows, in a sense, the eye itself to function as both a display and a camera. EyeTap is at once the eye piece that displays computer information to the user and a device which allows the computer to process and possibly alter what the user sees. That which the user looks at is processed by the EyeTap. This allows the EyeTap to, under computer control, augment, diminish, or otherwise alter a user's visual perception of their environment, which creates a Computer Mediated Reality. Furthermore, ideally, EyeTap displays computer-generated information at the appropriate focal distance, and tonal range. The figure below depicts and describes the basic functional principle of EyeTap. Note from the diagram that the rays of light from the environment are collinear with the rays of light entering the eye (denoted by the dotted lines) which are generated by a device known as the aremac. "aremac" is the word camera spelled backwards and is the device which generates a synthetic ray of light which is collinear with an incoming ray of light. Ideally, the aremac will generate rays of light to form an image which appears to be spatially aligned, and appears at with the same focus as the real world scene [http://www.eyetap.org/research/eyetap.html].
+
−
=====Fundamental operating principle of EyeTap=====
+
−
Rays of light which would have otherwise entered the eye are instead reflected by the diverter. The diverter is typically a double-sided mirror or a beamsplitter. These rays of light are collected by a sensor, typically a CCD camera. This camera data is processed, and the aremac redisplays the image as rays of light. The aremac (the word `camera' backwards), is a display device which is capable of displaying information at an appropriate depth. These rays reflect again off the diverter, and are then collinear with the rays of light from the scene. Thus the rays of light hitting the sceneward side of the diverter in a sense "pass through" the diverter by passing through the processor and aremac. The user perceives the virtual light. This virtual light can be either the same image, or a computer mediated version of the real world scene, since the virtual light is altered under computer control [http://www.eyetap.org/research/eyetap.html].

Definition

A wearable computer is a computer that is subsumed into the personal space of the user, controlled by the user, and has both operational and interactional constancy, i.e. is always on and always accessible. Most notably, it is a device that is always with the user, and into which the user can always enter commands and execute a set of such entered commands, and in which the user can do so while walking around or doing other activities". [1]

History

Blackjack

In 1961 mathematician Edward O. Thorp, best known as “The father of wearable computer" and Claude Shannon built the world’s first wearable computer, a computerized timing card-counting device for blackjack.[2]

WearComp

In 1981, while still in high school, Steve Mann designed backpack-mounted computer to control photographic equipment[3]. Mann felt that humans that computers and computing environments should be available anywhere to a person, not just at a specifically designed computer terminal. While enrolled in classes at MIT, Mann wore many pounds of computing equipment almost everywhere he went. As time progressed, computing became lighter, and Steve Mann’s load became less burdensome while still retaining the same functionality. In December 1994, Steve Mann developed the "Wearable Wireless Webcam." Webcam transmitted images point-to-point from a head-mounted analog camera to an SGI base station via amateur TV frequencies. The images were processed by the base station and displayed on a webpage in near real-time.[4]

Steve Mann envisioned a future in which hardware could be downloaded in as easily as software. Where one’s contact lens prescription could change during the day based on one’s needs. A future where a device morphs is the most fluid and liquid that an interface can become. Interfaces today are limited by their external structure. This limitation will dissolve when the hardware dissolves. Computers have diminished in volume from gymnasiums to desktops to pockets, and computer screens have become liquid, allowing buttons to appear anywhere they are needed. Although the Internet is invisible and seemingly omnipresent, it is only accessible by two-dimensional interfaces on physical machines in connected fields.

Dr. Mann's WearComp invention dates back to his high school days in the 1970s and early 1980s, where he was experimenting with wearable computing and personal imaging as a hobby [5]. "Unlike other wearable devices (wristwatches, regular eyeglasses, wearable radios, etc.), a WearComp is as reconfigurable as the familiar desktop or mainframe computer. Unlike other computers (including laptops and PDAs), a WearComp is inextricably intertwined with its wearer - WearComp's "always ready" characteristic leads to a new form of synergy between human and computer".[6]

Active Badge

In 1990 Italian computer manufacturer Olivetti developed an active badge system[7]. The badges were worn around the neck and operated only in specially-wired buildings, where each room and door has an infra-red tranceiver to communicate with the badge.[8] The Active Badge used using infrared signals to communicate a person's location: Olivetti developed a name badge that transmitted a unique id to IR receivers placed in rooms around a building. This allowed these "smart rooms" to track a person's location and log it in a central database.

Much of what was possible with early wearable computing is now possible with mobile phones. David Greaves wore an Active Badge at Cambridge University to unlock the buildings where he worked and to give out his location.[9]. Although the Active Badge was useful, Greaves mentioned his colleagues "stopped wearing their badges in the office environment once they had a mobile phone".[10]

Guidelines for Wearable Computing

Steve Mann formally defined wearable computing in terms of its three basic modes of operation and its six fundamental attributes.[11][12]

Operational Modes of Wearable Computing

Mann defined three operational modes in this new interaction between human and computer, and six informational flow paths.[13] The three operational modes and their attributes will be listed here. For further reading, see the references section of this entry. It is recommended that anyone working on wearable computing read Mann's work on the Eyetap and follow the full set of guidelines for wearable computing.

Constancy Augmentation Mediation Solitude Privacy
The computer runs continuously, and is always ready to interact with the user. Unlike a hand-held device, laptop computer, or PDA, it does not need to be opened up and turned on prior to use. The signal flow from human to computer, and computer to human runs continuously to provide a constant user interface. Traditional computing paradigms are based on the notion that computing is the primary task. Wearable computing, however, is based on the notion that computing is NOT the primary task. The assumption of wearable computing is that the user will be doing something else at the same time as doing the computing. Thus the computer should serve to augment the intellect, or augment the senses. Unlike hand held devices, laptop computers, and PDAs, the wearable computer can encapsulate us. It doesn't necessarily need to completely enclose us, but the concept allows for a greater degree of encapsulation than traditional portable computers. It can function as an information filter, and allow us to block out material we might not wish to experience, whether it be offensive advertising, or simply a desire to replace existing media with different media. In less severe manifestations, it may simply allow us to alter our perception of reality in a very mild sort of way. Mediation allows us to block or modify information leaving our encapsulated space. In the same way that ordinary clothing prevents others from seeing our naked bodies, the wearable computer may, for example, serve as an intermediary for interacting with untrusted systems, such as third party digital anonymous cash "cyberwallets".

Future of Wearable Computing

The best wearable computers will evaporate over time until they are no longer noticeable or are proper ubiquitous extensions of the self, as valuable and as iconic as sports cars and external transport structures for the physical body. Their interfaces will be invisible. All that is solid will melt into air.
