One problem with developing pervasive computing systems is making them, well, pervasive. To deploy computers and networking services everywhere that users might travel requires prohibitive expenses in infrastructure and maintenance. However, there is an alternative: wearable computers. By carrying

Since 1993, members of the MIT Wearable Computing Project have been engaged in a "living experiment, " incorporating wearable computing into their everyday lives. Such immediate access to computation power enables a unique lifestyle and has many social implications. Through the use

User interaction and context awareness are key issues in today’s wearable computing research. Context-aware wearable devices typically use a multitude of special purpose sensors for this. In this paper, we show for a simple test case that even simple sensors in a wearable human computer interaction

objects. Both interfaces run on commercially available wearable computers, and they demonstrate how Mixed Reality techniques can be used to overcome the limitations of traditional video and audio conferencing.

, guiding him through the building and showing virtual beacons of patients ’ locations. Such scenarios will be possible in the near future with wearable computers supporting augmented reality (AR). This article explores wearable AR concepts, presents applications, and peeks into the near future of its

E ye-based human-computer inter-action (HCI) goes back at least to the early 1990s. Controlling a computer using the eyes traditionally meant extracting information from the gaze—that is, what a person was look-ing at. In an early work, Robert Jacob investigated gaze as an input modality

Firefighters work in dangerous and unfamiliar situations un-der a high degree of time pressure and thus team work is of ut-most importance. Relying on trained automatisms, firefight-ers coordinate their actions implicitly by observing the ac-tions of their team members. To support training instructors with objective mission data, we aim to automatically detect when a firefighter is in-sight with other firefighters and to vi-sualize the proximity dynamics of firefighting missions. In our approach, we equip firefighters with smartphones and use the built-in ANT protocol, a low-power communication radio, to measure proximity to other firefighters. In a second step, we cluster the proximity data to detect moving sub-groups. To evaluate our method, we recorded proximity data of 16 professional firefighting teams performing a real-life training scenario. We manually labeled six training sessions, involv-ing 51 firefighters, to obtain 79 minutes of ground truth data. On average, our algorithm assigns each group member to the correct ground truth cluster with 80 % accuracy. Considering height information derived from atmospheric pressure signals increases group assignment accuracy to 95%.

This paper provides a general overview of tactual displays (i.e., devices that communicate to a user through the sense of touch) and issues concerning the development of such displays for wearable computing. ,4 wearable tactile directional display is presented. It takes advantage of a sensory

Primary Tasks in Wearable Computing In this paper we present a novel apparatus for simulating real world primary tasks typically found in wearable computing. Additionally, we report on a preliminary interruption study using the new apparatus in a laboratory experiment and compare its results

We present two real-time hidden Markov model-based systems for recognizing sentence-level continuous American Sign Language (ASL) using a single camera to track the user’s unadorned hands. The first system observes the user from a desk mounted camera and achieves 92 percent word accuracy. The second system mounts the camera in a cap worn by the user and achieves 98 percent accuracy (97 percent with an unrestricted grammar). Both experiments use a 40-word lexicon.
