Abstract
An interaction method between a graphic tactile device such as a smartphone and a timepiece having at least two analog-type physical pointers is disclosed. Each of the pointers is controlled independently by a stepper motor and referenced relative to a ref-position. The timepiece comprises a control unit configured to handle time count and to control stepper motors. The smartphone has a value setting interface, and the timepiece and the smartphone communicate through a wireless remote short-range communication link. The method comprises the steps of initiating a calibration procedure, causing the minute pointer to be moved to the ref-position via the value setting interface, causing the hour pointer to be moved to the ref-position via the value setting interface, and ending the calibration procedure, and return to a normal time display, Thereby, starting from an initial unknown pointer positions, the control unit of the timepiece can accurately know the positions of pointers.
