Advanced displays and natural user interfaces (NUI) are a very suitable combination for developing systems to provide an enhanced and richer user experience. This combination can be appropriate in several fields and has not been extensively exploited. One of the fields that this combination is especially suitable for is education. Nowadays,…

Aim: Cerebral visual impairment (CVI) is a disorder caused by damage to the retrogeniculate visual pathways. Cerebral palsy (CP) and CVI share a common origin: 60 to 70% of children with CP also have CVI. We set out to describe visual dysfunction in children with CP. A further aim was to establish whether different types of CP are associated with…

A developmental study of the relation between apparent size and pictorial depth demonstrated the usefulness of operant techniques in establishing equivalent differential responding and interesting stimulus equivalence in adults, 9- and 3-year-olds. (Author/AJ)

A visually directed sensory motor training program with a 30-day duration did not enhance the depth perception of five-year-old children. (MM)

Results of this study suggest that 3-year-olds have a good deal of sensitivity to static depth information. (Authors)

Tests the hypothesis that children will be better than adults at perceiving depth at large disparities in random-dot stereograms. Subjects were 4, 6, 8, and 25 years of age, with six males and six females in each of the four age groups. (MP)

Examines the use of pictures by different learners in different ways, and presents guidelines for using pictures in teaching culturally diverse children. The degree of complexity versus simplicity is discussed, the need for effective directional cues is emphasized, and depth and motion cues are described. (LRW)

Investigates the ability of Malawians ranging from 7 through 23 years of age to make judgements of the relative sizes and spatial locations of objects in photographic scenes with restricted cues to depth. All age groups responded with an accuracy significantly above chance. Exhibiting maximum scores, adults were significantly more accurate than…

This study concerns children's understanding of spatial relationships and their expression in drawings and photographs. Sixty children (ages 5, 8, and 11) were asked to discriminate and reproduce three types of depth relationships in either drawings or photographs: enclosure, where a larger object is placed directly behind a smaller object;…

Tries to unravel some of the problems concerning the previous finding that increasing the number of depth cues in pictures has a depressing effect on spatial accuracy of three dimensional reconstruction of pictures. Evidence does not support a deficiency in perceiving pictorial depth in African children. (AM)

In this study of sensitivity to viewpoint, children between the ages of 6 and 14 years were asked to draw an L-shaped array of 3 cubes from 1 of 3 views. At every age, children showed sensitivity to their view in the sense that there were consistent differences between the drawings produced in the three viewing conditions. (SH)

An experimental test of visual closure based on an information-theory concept of perception was devised to test the ability to discriminate visual stimuli with reduced cues. The test is to be administered in a timed individual situation in which the subject is presented with sets of incomplete drawings of simple objects that he is required to name…
