AgentsAgents A premise of a wearable computer is that the computer can A premise of a wearable computer is that the computer can

learn and become customized to the user's needs, based upon learn and become customized to the user's needs, based upon the task the user is involved with. If the user is viewing a the task the user is involved with. If the user is viewing a document, the Wearable Computer may suggest an associated document, the Wearable Computer may suggest an associated email, showing minimal information such as the subject, sender, email, showing minimal information such as the subject, sender, date, or what ever information the user would want to view to get date, or what ever information the user would want to view to get a sense as to decide whether the entire email should be retrieved. a sense as to decide whether the entire email should be retrieved.

Humans are poor at data retrieval, and a complex hierarchical Humans are poor at data retrieval, and a complex hierarchical directory quickly breaks down when the human user loses the directory quickly breaks down when the human user loses the thread of where the item being searched for resides. A computer thread of where the item being searched for resides. A computer remembrance agent can take cues from this environment to remembrance agent can take cues from this environment to assist in locating appropriate files from memory, picking up on assist in locating appropriate files from memory, picking up on cues like where the user is, is the user alone or with someone , what cues like where the user is, is the user alone or with someone , what is the user doing at that time, etc., all can be used to search is the user doing at that time, etc., all can be used to search and locate appropriate files that may be relevant to the user at and locate appropriate files that may be relevant to the user at that time. In this manner the computer is a continual presence, that time. In this manner the computer is a continual presence, always 'looking over the shoulder' of the user. For example, at a always 'looking over the shoulder' of the user. For example, at a staff meeting the Wearable Computer can assist in remembering staff meeting the Wearable Computer can assist in remembering names of attendees, who was at the meeting prior, what they names of attendees, who was at the meeting prior, what they said at that time, what was on the agenda, and also to suggest said at that time, what was on the agenda, and also to suggest topics which might be of relevance to what was going. The topics which might be of relevance to what was going. The computer is always active in searching the user's own personal data computer is always active in searching the user's own personal data base for information which might prove useful within the context of base for information which might prove useful within the context of the current task the user is performing. the current task the user is performing.

Our emotions play a significant role in our every day life, and up to Our emotions play a significant role in our every day life, and up to now, this had been unrepresented within human computer now, this had been unrepresented within human computer interfaces. Human vital signs such as blood pressure , interfaces. Human vital signs such as blood pressure , temperature, galvanic skin response, foot pressure and temperature, galvanic skin response, foot pressure and electromyograms can be tracked and monitored through the use of electromyograms can be tracked and monitored through the use of body sensors connected into the wearable computer. In this body sensors connected into the wearable computer. In this manner, the computer becomes physically connected to the user manner, the computer becomes physically connected to the user and can learn to recognize physiological states . By this monitoring and can learn to recognize physiological states . By this monitoring of body vital signs and learning how the user reacts when in of body vital signs and learning how the user reacts when in different feeling and mood states, the computer can different feeling and mood states, the computer can take action accordingly. For example, if the user likes to hear take action accordingly. For example, if the user likes to hear a certain type of music at one time and another during a different a certain type of music at one time and another during a different mood state, the computer can plan on providing this to the user at mood state, the computer can plan on providing this to the user at the appropriate times. the appropriate times.

The affective sensors could also be of assistance in medical The affective sensors could also be of assistance in medical monitoring where important health data might be tracked and monitoring where important health data might be tracked and reported directly to the user’s physician. They list four bio-sensors reported directly to the user’s physician. They list four bio-sensors used in a current prototype affective wearable system: measuring used in a current prototype affective wearable system: measuring respiration , skin conductivity, blood volume pressure and respiration , skin conductivity, blood volume pressure and electromyogram, all of which the sensors can monitor electromyogram, all of which the sensors can monitor painlessly from the surface of the skin. These four sensors are painlessly from the surface of the skin. These four sensors are monitored via a Linux operating system, and can be sampled up monitored via a Linux operating system, and can be sampled up to 20 times per second. Affective computing employs its own to 20 times per second. Affective computing employs its own intelligent agent which can make decisions based upon intelligent agent which can make decisions based upon analysis of the incoming environmental and physiological sense analysis of the incoming environmental and physiological sense data. data.

Future ResearchFuture Research

Future research and development issues include the Future research and development issues include the following:following:

Ergonomic research - best method to utilize Ergonomic research - best method to utilize components, e.g. - the head set such that it is components, e.g. - the head set such that it is comfortable and is helping and not distracting the user comfortable and is helping and not distracting the user from the task. There needs to be more light weight from the task. There needs to be more light weight efficient and easily powered computer apparatus which efficient and easily powered computer apparatus which is comfortable to wear.is comfortable to wear.

tactical use of Wearable Computer are going on around tactical use of Wearable Computer are going on around the world. Several types of Wearable the world. Several types of Wearable Computer’s are indeed commercially available, but Computer’s are indeed commercially available, but as of now most of them are tailor made for as of now most of them are tailor made for specific applications. It is only a matter of time specific applications. It is only a matter of time before the consumer community accepts the idea. The before the consumer community accepts the idea. The shift that the Wearable Computer’s will bring;computer shift that the Wearable Computer’s will bring;computer working along with you instead of you working at the working along with you instead of you working at the computer.Though the wearable has not seen the computer.Though the wearable has not seen the widespread acceptance given to the desktop, work widespread acceptance given to the desktop, work continues in this field to meet the challenges that continues in this field to meet the challenges that inhibit its growth. Processors and sensors need to be inhibit its growth. Processors and sensors need to be effectively integrated into textiles; and displays, whether effectively integrated into textiles; and displays, whether head or body mounted, need to effective under a wide head or body mounted, need to effective under a wide range of lighting conditions - all of these must be range of lighting conditions - all of these must be comfortable to wear comfortable to wear
