Abstract:

The problem solving skills development system is used, for example, as a puzzle or game, to develop problem solving or analytical skills in visually impaired individuals. The system includes a supporting board having sliding pieces arranged in a grid, for example, a 4 by 4 grid of 15 sliding pieces and one empty position. The sliding pieces include tactilly recognizable regions that are arranged into a predetermined pattern by sliding and shifting the appropriate pieces. The tactilly recognizable regions can include characters, such as letters that can be arranged to form words or phrases, numbers that can be arranged in numerical order, or any other symbols. Some of the tactilly recognizable regions can also include blank surfaces to make the puzzle easier for individuals at lower ages or abilities. The system preferably includes tactile recognition blocks that have the tactilly recognizable regions and that can be removably engaged with the sliding pieces. The tactile recognition blocks can thereby be used to adapt the system to be used as different types of puzzles with different degrees of difficulty.
