This paper describes our exploration of a design space for an augmented reality prototype. We began by observing air traffic controllers and their interactions with paper flight strips. We then worked with a multidisciplinary team of researchers and controllers over a period of a year to brainstorm and prototype ideas for enhancing paper flight strips, We(More)
Human-computer interaction is multidisciplinary, drawing paradigms and techniques from both the natural sciences and the design disciplines. HCI cannot be considered a pure natural science because it studies the interaction between people and artificially-created artifacts, rather than naturally-occurring phenomena, which violates several basic assumptions(More)
Pseudohypoparathyroidism Ia (PHP Ia) is characterized by resistance to PTH and many other stimuli because of deficiency of stimulatory G protein alpha-subunit. To determine the incidence, natural history, and mechanism of C cell dysfunction in PHP, calcitonin assays were performed in six patients with PHP Ia and four with pseudopseudohypoparathyroidism from(More)
Augmented Reality offers a new paradigm for interacting with computers, linking familiar, physical objects to powerful computer networks. Although still in its infancy, the field is expanding rapidly, due to a wealth of new materials and technologies and a shift away from conventional notions about human-computer interaction. The increasing power and(More)
This tutorial is designed for HCI designers and researchers interested in learning specific techniques for using video to support a range of participatory design activities. Based on a combination of lectures, video demonstrations and hands-on exercises, the tutorial will give participants practical experience using video to observe users in laboratory and(More)
