Overview Talk: Humans, computers, delays and the joys of interaction

Ragnhild Eg | Westerdals Oslo School of Arts, Norway

Abstract: Computers make humans wait. When interacting with a computer system, no response is instant; every key stroke or mouse movement must be processed before the output is rendered and presented. If signals have to travel across a network, the waiting time, or latency, can extend into the perceptible and further into the detrimental. In addressing perceptible delays between motor inputs and visual outputs, different communities use different jargons. Yet they share a common interest in the perceptual and cognitive consequences of lagging responses. This talk will give an overview of current insights about temporal human-computer interactions, presenting findings from HCI, multimedia and psychological research.

She completed a PhD in psychology at the University of Oslo while working at Simula Research Laboratory. At Simula, she was part of a multi-disciplinary project that focused on the human perception of multimedia. Current projects relate to temporal human-computer interactions and the impact of delayed responses on performance. Ragnhilds research interests relate to the perceptual processing and integration of sensory information, particularly how the perceptual process is affected by the constraints imposed by technology.
