Physiological computing involves the direct interfacing of human physiology and computer technology, i.e. brain-computer interaction (BCI). The goal of physiological computing is to transform bioelectrical signals from the human nervous system into real-time computer input in order to enhance and enrich the interactive experience. Physiological computing has tremendous potential for interactive innovation but research activities are often disparate and uneven, and fail to reflect the multidisciplinary nature of the topic. This paper will provide a primer on detectable human physiology as an input source, a summary of relevant research and a research agenda to aid the future development of interactive systems that utilise physiological information. q
Applications involving the measurement of human physiological responses to environment are becoming increasingly popular in HCI. This is due in part to the increasing availability of low-cost, high-specification sensing technologies. Areas such HCI evaluation, affective computing and biofeedback-based brain-computer interaction are all benefiting from the rich data source physiological sensing technologies make available. However, guidelines on the gathering and analysis of these measurements are virtually non-existent, which makes it difficult for new researchers to practise in this area. This timely workshop will bring together both practising and potential researchers using this method to gather knowledge on the techniques, technologies and applications of physiological computing.
This paper describes the design and evolutionary development of a system for supporting informal interactions between geographically-remote members of a group. Based on simple internet technologies, the system described enables the use of novel, tangible devices for the purpose of discrete event notification. A simple system was initially developed for use in an office environment for providing awareness events via a single notification device. Over a four month period this simple system evolved into a suite of low-cost, low-tech notification devices for public and personal use. The numerous devices utilised by the final system constitute a physical landscape of awareness which have been demonstrated to support group and individual awareness of discrete events in both fixed locations and on the move.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
