The purpose of the present study was to examine the effects of S-Block curriculum on children's logical-mathematical and spatial ability. S-Block is a smart toy system that integrates IOT technology with a traditional block toy. The S-Block curriculum included storytelling component with a specific task, which encouraged children to solve the problem using S-Block system. Participants were 26(13 experimental group, 13 control group) 5-year-old-children. The study results revealed significantly positive gains in the children's logical-mathematical performance and spatial ability. Suggestions for developmentally appropriate technology in early childhood and curriculum integration are provided.

We optimize automultiscopic displays built by stacking a pair of modified LCD panels. To date, such dual-stacked LCDs have used heuristic parallax barriers for view-dependent imagery: the front LCD shows a fixed array of slits or pinholes, independent of the multi-view content. While prior works adapt the spacing between slits or pinholes, depending on viewer position, we show both layers can also be adapted to the multi-view content, increasing brightness and refresh rate. Unlike conventional barriers, both masks are allowed to exhibit non-binary opacities. It is shown that any 4D light field emitted by a dual-stacked LCD is the tensor product of two 2D masks. Thus, any pair of 1D masks only achieves a rank-1 approximation of a 2D light field. Temporal multiplexing of masks is shown to achieve higher-rank approximations. Non-negative matrix factorization (NMF) minimizes the weighted Euclidean distance between a target light field and that emitted by the display. Simulations and experiments characterize the resultingcontent-adaptive parallax barriersfor low-rank light field approximation.
