    Heart-rate sensing is very important. Whereas there are different methods and commercial products available, they all have a common drawback: the user has to mount some piece of sensor to his body. This paper provides a case study on how micro-impulse radar (MIR) can be used to sense heart-rate in a contact-free manner. With a sequence of tests the robustness of radar to different placements and e... View full abstract»

    Hand gesture-based interface is one of the most promising modes of natural and fluid human-computer interaction that substitutes for the mouse and keyboard in wearable computing systems. In wearable computing scenarios, hand positioning and tracking is particularly difficult due to complex background, lighting variation and image dithering caused by head movement. This paper proposes a robust hand... View full abstract»

    Unobtrusive sensors are an important element in wearable systems. One approach in constructing unobtrusive transducers is to use smart materials and then integrate them into smart unobtrusive fabric structures. These types of transducers are called fabric transducers (Fibre-Meshed Transducers or FMTs). Fabrication is carried out via textiles manufacturing processes. In this paper we have discussed...

    In this paper, we describe an autonomous, wearable electronic textile location awareness system that will determine a user's location within a building given a map of that building. The system uses a moderate number of ultrasonic range transceivers as the sensing elements. Given a set of range readings from these sensors, the system attempts to match those actual readings to expected readings asso... View full abstract»

    The wearable active camera/laser (WACL) allows the remote collaborators not only to independently set their viewpoints into the wearer's workplace but also to point to real objects directly with the laser spot. In this paper, we report a user test to examine the advantages and limitations of the WACL interface in remote collaboration by comparing a head-mounted display and a head-mounted camera-ba...
