Following the ecological approach to visual perception, this paper presents a framework that emphasizes the role of vision on referring actions. In particular, affordances are utilized to explain gestures variability in a multimodal human-computer interaction. Such a proposal is consistent with empirical findings obtained in different simulation studies showing how referring gestures are determ...

A study is presented examining the participatory design of digital musical interactions. The study takes into consideration the entire ecology of digital musical interactions including the designer, performer and spectator. A new instrument is developed through iterative participatory design involving a group of performers. Across the study the evolution of creative practice and skill developme...

Mobile context aware decision support systems have the potential to provide workers with the information they need, when they need it. The design of such systems must take into account the organisation of information, the activities of the worker, and the wider sociotechnical system if they are to work effectively. Cognitive Work Analysis (CWA) has been applied extensively to the design of deci...

Previous studies have shown adaptive cruise control (ACC) can compromise driving safety when drivers do not understand how the ACC functions, suggesting that drivers need to be informed about the capabilities of this technology. This study applies ecological interface design (EID) to create a visual representation of ACC behavior, which is intended to promote appropriate reliance and support ef...

Interfaces designed according to ecological interface design (EID) display higher-order relations and properties of a work domain so that adaptive operator problem solving can be better supported under unanticipated system conditions. Previous empirical studies of EID have assumed that the raw data required to derive and communicate higher-order information would be available and reliable. The ...

Four approaches to interface design are considered: technology centered, user centered, control centered, and use centered (ecological). Each perspective provides unique insights into pieces of the interface design problem. However, it is argued that the ecological or use centered approach provides a more comprehensive framework within which the other three perspectives can play important suppo...

We present high-frequency angle-dependent EPR data for crystals of fNixZn1−xshmpdstBuEtOHdClg4 sx=1 and 0.02d. The x=1 complex behaves as a single-molecule magnet at low temperatures, displaying hysteresis and exceptionally fast magnetization tunneling. We show that this behavior is related to a fourth-order transverse crystal-field interaction, which produces a significant tunnel splitting s,1...

In a Free Flight Environment, safe –separations are delegated to the pilot by the Air Traffic Control. An adoption of a Free Flight Environment is considered vital as air traffic is predicted to double over the next two decades. Transitioning from the current Controlled Airspace to Free Flight Environment involves number of changes. A pilot role is to change to airspace and decision manager. Pi...

Using an international dataset compiled from 121 sites in 87 marine protected areas (MPAs) globally (Edgar et al., 2014), I assessed how various configurations of design and management conditions affected MPA ecological performance, measured in terms of fish species richness and biomass. The set-theoretic approach used Boolean algebra to identify pathways that combined up to five 'NEOLI' ( No-t...
