Enabling the blind to see gestures - Francisco Oliveira - Bog

The blind is perfectly capable of learning mathematics. Special printers can be used to produce instruction material with raised line drawings. Despite having access to the graphical illustration, the blind cannot follow the teacher''s pointing gestures. We developed the Haptic Deictic System (HDS) which allows the blind to understand such gestures. In this book, we address issues from the conception through the design, implementation, evaluation to the effective and successful use of the HDS in inclusive classrooms.
