Visual perception process and its relation to formal recognition

The article surveys the data of experimental studies in which the corneal reflex was used in the analysis of the visual perception process. Visual perception largely depends on the physiological characteristics of the human visual system, both individual and general. Blinking performs a number of functions, one of which is protection, including protection from unpleasant or undesired information. Blinking is closely related to the processes of concentration and disinterest. Blinking while watching a video is synchronized in single person and in a group of people watching the same video fragment. Blinking synchronization depends on the video plot; background video does not cause synchronization. Blinking synchronization is not gender specified. A longer duration of blinking is associated with a significant increase of the intervals between blinks. Accounting for these features of visual perception will allow to coordinate the work with video in several ways. First of all, it is an analysis of the reaction by monitoring the blinks while watching the video. Such analysis should contain a detailed and comprehensive decoding including electrophysiological, psychological and psychophysiological tools. Thus, the analysis of visual perception by studying the corneal reflex components requires an interdisciplinary approach and should be targeted to getting the results usable both for further studies of psychological features and principles of human visual perception and for further creation of most effectively perceived video.

Perception Visuelle

AbstractThe main aim of this article is to describe the visual perception process of anticipatory rounding gestures in [iC(CCCC)y] sequences by considering the characteristics that contribute to their production (articulatory configurations, temporal data, and kinematic events). Productions of two French speakers were analyzed to obtain the data needed to interpret the results of a perception test composed of truncated visual sequences using thegatingparadigm. The results indicate that the perceptually effective portion of the gesture usually begins when a significant velocity peak is observed. In contrast, if the sequence has no prominent velocity peak, the rounded vowel can be recognized only when the labial configurations are closer to the articulatory target. The results can be interpreted on the basis of general models for movement perception, in this caserepresentational momentum.
