VAZQUEZ-REYES, Sodel et al. Projective Mapping: the base function of the WiimoteWhiteboard. RISTI [online]. 2015, n.spe3, pp.85-92. ISSN 1646-9895.  https://doi.org/10.17013/risti.e3.85-92.

Nowadays, many emerging projects focus mainly in developing low cost interactive whiteboards, having the Wiimote as their main working tool. However, although there is a lot of information about these projects and how to implement these interactive whiteboards, only few people know how this project really works. This article describes the base algorithm of the low cost interactive whiteboards, which is based in projective transformations, using a homography matrix. The implementation of this technology in Mexican educative institutions could reinforce learning processes at all levels, without the need to spend too much. This is a collateral advantage of information technology re-engineering.

Palavras-chave : homography; interactive board and matrix operations.
