The method comprises: detecting a customer's hand placed palm downwards on the multi-touch surface (14) and detecting the customer's hand pivoting upwards from the detected palm downwards position so that an edge of the hand is placed on the multi-touch surface (14). The method also comprises displaying a private interaction window (120) located adjacent to, and on the palm side of, the customer's hand; and communicating private data on the private interaction window (120). The private interaction window (120) is dimensioned to be shielded by the customer's hand.</p> |
