Visual Activity in Hollywood Film: 1935 to 2005 and Beyond

The structure of Hollywood film has changed in many ways over the last 75 years, and much of that change has served to increase the engagement of viewers’ perceptual and cognitive processes. We report a new physical measure for cinema—the visual activity index (VAI)—that reflects one of these changes. This index captures the amount of motion and movement in film. We define whole-film VAI as (1 ...

Rule Consistency Jaap Hage

This paper develops the theory that a set of rules is consistent if it is not possible that: 1) the conditions of the rules in the set are all satisfied, 2) there is no exception to either one of the rules, and 3) the consequences of the rules are incompatible. To this purpose the notion of consistency is generalised to make it cover rules and is relativised to a background of constraints. The ...

Roger Needham, 1935-2003

Cambridge Research Lab, which he founded in 1997. Prior to joining Microsoft, he was associated with Cambridge University for nearly half a century—as an undergraduate and graduate student, as a researcher, and eventually as a professor and head of the Computer Laboratory. In this EIC message, I focus on the significance of Needham's research contributions to pervasive computing. These contribu...

Alan Cowey (1935–2012)

Alan's work was necessarily interdisciplinary because he saw no way of understanding anatomy, physiology or behaviour without understanding all of them. Hence his work on visual plasticity and development incorporated retinal and collicular anatomy, lesion studies and neuropsychological work with patients. This led him to take up the discovery of blindsight by Larry Weiskrantz, his graduate sup...
