Major Limitation • One tag at a time • Tag could not be recognized behind an LCD

ConclusionGaussToys Hackathon 2015

• The combination of a robust ID mechanism with magnetic tangibles effectively support applications that involve many tangible objects.

• The proposed toolkit is useful in content development.
