This paper reports on the development of a hand to machine interface device that provides real-time gesture, position and orientation information. The key element is a glove and the device as a whole incorporates a collection of technologies. Analog flex sensors on the glove measure finger bending. Hand position and orientation are measured either by(More)
This thesis presents a system for describing the pitch-time structure of a musical dialect or "style". The music description system is built from a constraint language, which is itself a natural extension of modern engineering and simulation "kits". Several of the most common musical concepts are defined as expressions in the kernel language. These include(More)
OBJECTIVE To assess the prevalence of severe welfare problems in horses that arrive at slaughter plants and to identify horses that were unfit for travel. DESIGN Prevalence survey. ANIMALS 1,008 horses. PROCEDURE Horses arriving at 2 slaughter plants were observed. The following were rated severe welfare problems in horses: body condition scores of 1(More)
I find myself holding a passionate opinion that almost nobody in the " Wired-stple " community agrees with and I'm wondering; What's gotten into all of you? I find that in the wide, though shrinking world away from computers most people find my position obvious, while infophiles find it impenetrable. I am trying to bridge a chasm of misunderstanding. Here(More)
Casual observations indicated that some cattle are more sensitive to sudden movement or intermittent sound than other cattle. Six commercial livestock auctions in two states and a total of 1,636 cattle were observed to assess the relationship between breed, sex, and temperament score on the response to sudden, intermittent visual and sound stimuli, such as(More)
Novel avatar bodies are ones that are not controlled in a one-to-one relationship between the user's body and the avatar body; for example, when the avatar's arms are controlled by the user's legs, or, when the avatar has a third arm. People have been shown to complete tasks more successfully when controlling novel avatar bodies than when controlling(More)
Researchers have been working with head mounted displays and virtual reality (VR) since 1965 when Ivan Sutherland published his first paper on the subject<sup>1</sup>. This work has centered on a single user within virtual space. The literature has covered applications such as telerobotics, virtual control panels, architectural simulation and scientific(More)
Immersive virtual reality allows people to inhabit avatar bodies that differ from their own, and this can produce significant psychological and physiological effects. The concept of homuncular flexibility (Lanier, 2006) proposes that users can learn to control bodies different from their own by changing the relationship between tracked and rendered motion.(More)
I really apologize. I promised everyone I would come out wearing the data suit, but it just slipped my mind and I never got around to it. Actually Marvin Minsky was saying that the thing to do would be to come out with nothing on because that would be the perfect interface to the computer. So I kind of shunned the whole thing off at that point.We just heard(More)
