It supports 10 people to write at the same time. The students come to the stage together to write answers and draw a picture by hand. The infinite space for collaboration is derived from TVISION's advanced touch technology, which is highly sensitive and accurate. It is comparable to pen writing, and multiple people's writing interferes with each other.
