A custom sized 15.2” Zytronic Zyfilm® together with a ZXY150 multitouch controller were selected following a comprehensive performance evaluation. A key requirement was that the touch sensor responded reliably from its location underneath an 8mm thick melamine chopping board, with the kitchen surface and foods all projected onto the surface from an overhead projector. For this application, the touch controllers “palm rejection” algorithm was disabled, so that for example, if a child used a hand to flatten a piece ‘virtual’ chicken with a palm, the touch controller would recognise this, and Bandai Namco’s software would respond appropriately. The system designers appreciated the fact that set up values are stored on the ZXY150 touch controller itself, eliminating the need to store them on the host PC, and improving servicing.
