Time Concerns

'Many researchers have made an effort to understand the human thinking and action processes that support design creativity and efficiency (Arciszewski et al., 1995). Several explanatory and predictive models have been developed. One of them, introduced by Horvath et al (2003b) tries to explain these capacities with the concepts of cognitive theory. It identifies an inner cognitive loop (including ideation, reasoning and presentation) and an external loop (including reasoning, presentation and constructive model development) Typically the timeframe of the mental actions forming the inner loop is 10^-1 - 10^-2 seconds, while the time frame for the modeling actions can be as large as 10-100 seconds. This scheme suggests that the speed of modeling actions and the mental actions should be as close as possible, in order to not become a burden on creative thinking. In other words, it is expected from the user interface of Advanced Design Support (ADS) systems that the time needed for creating a component of a product model (e.g. a surface) should be about the speed of human thinking, and not be longer than approximately a second.'
