PURPOSE To compare the results of visual acuity testing in a population of deaf children using the Handy Eye Chart versus the Lea Symbols Chart and to compare testability and preference between charts. METHODS A total of 24 participants were recruited at the Atlanta Area School for the Deaf. Visual Acuity was evaluated using the Handy Eye Chart and the Lea Symbols Chart. Patient preference an...

Parsing human poses in images is fundamental in extracting critical visual information for artificial intelligent agents. Our goal is to learn selfcontained body part representations from images, which we call visual symbols, and their symbolwise geometric contexts in this parsing process. Each symbol is individually learned by categorizing visual features leveraged by geometric information. In...

Self-localization is the process of identifying one’s current position on a map, and it is a crucial part of any wayfinding process. During self-localization the wayfinder matches visually perceptible features of the environment, such as landmarks, with map symbols to constrain potential locations on the map. The success of this visual matching process constitutes an important factor for the su...

Introduction: Modern medical devices and their user interfaces apply increasingly more graphical symbols to convey information. Previous researches have indicated some advantages of graphical symbols in conveying information: a) high visual impact to transmit information effectively; b) compact information which occupies less space on products; c) information independent of national languages, ...

Is selective rehearsal possible for nonverbal information? Two experiments addressed this question using the item method directed forgetting paradigm, where the advantage of remember items over forget items is ascribed to selective rehearsal favoring the remember items. In both experiments, difficult-to-name abstract symbols were presented for study, followed by a recognition test. Directed for...

This paper presents an approach for action recognition performed by human using the joint angles from skeleton information. Unlike classical approaches that focus on the body silhouette, our approach uses body joint angles estimated directly from time-series skeleton sequences captured by depth sensor. In this context, 3D joint locations of skeletal data are initially processed. Furthermore, th...

in during contemporary, its few of artists for numerous changes in artistic creation who have cared to reproduce some special symbols. in fact, these symbols are minor contain to the beliefs, cultures and values of people in the country. one of the most important artists is jazeh tabatabaie, painter and sculptor, devoting significant share to review of symbols. he recreated some of the symbols ...

BACKGROUND Symbols have been used in health state valuation studies to help subjects distinguish the severity of various characteristics of a given health state. Symbols used in such studies need to be evaluated for their cross-cultural appropriateness because a given symbol may have different meanings or acceptability in different cultures, which may affect results of such studies. OBJECTIVE...

BACKGROUND Prior studies have shown a consistent reduction of the auditory P300 in schizophrenia, while the visual attention findings have been mixed. Both the auditory and visual N2b, an earlier, modality-specific attention index, are reduced in schizophrenia, sometimes despite sparing of the visual P300. Thus there may be a dissociation between the N2b and P300 attention effects in auditory a...
