Launched in 2003 with the ClassPad 300, the ClassPad series features a Computer Algebra System (CAS) developed by Casio and pentouch operations using a stylus.
As OEMs also look to implement more flexible input options for consumers, the Synaptics ClearPad 3400 allows simultaneous pen and finger touch recognition, passive pen tracking with pinpoint accuracy, and linearity and jitter control that functions with any number of fingers and styluses as small as 2mm.
