Analog type watch and time set method
First Claim
1. Interaction method between on the one hand a smartphone or a tablet and on the other hand a watch having at least two analog-type pointers, controlled by a stepper motor and referenced relative to a zero-position, the watch and the smartphone being able to be in communication through a wireless remote short-range communication link, the method comprising the steps:
- S1—
capturing image(s) of the watch with the smartphone,S2—
processing the image(s) to determine accurately the displayed angular positions of the pointers,S3—
sending correction data from the smartphone to the watch, said correction data comprising the so-determined displayed angular positions of the pointers, and/or angular deviations from a reference position,S4—
carrying out, at the watch, an appropriate correction so that the pointers are caused to display the current absolute time,whereby a possible pointer inadvertent drift can be readily corrected, in which during step S1, an overlay with a special frame is provided on a screen of the smartphone to improve alignment of the watch while shooting image(s) with the smartphone, whereby easing the subsequent processing of the image(s).

Abstract
Interaction methods between a smartphone and a timepiece having two analog-type pointers, each of the pointers being controlled independently by a stepper motor, the timepiece and the smartphone being able to be in communication through a wireless remote short-range communication link, the calibration method comprising the steps of S1—capturing image(s) of the watch with the smartphone, S2—processing the image(s) to determine accurately the displayed angular positions of the pointers, S3—send correction data from the smartphone to the watch, S4—carry out, at the watch, an appropriate correction so that the pointers are caused to display the current absolute time, the absolute time set method comprising the steps of S11—send absolute time reference from the smartphone to the watch, S12—carry out, at the watch, an appropriate correction, to update the internal counters and positions of the pointers so that the pointers display the current absolute time.
