Abstract

A method for managing an operation for a watch to exit standby mode, the watch being provided with a dial having a digital display, and placed into a standby mode, in which the dial is off, includes storing, in a memory of the watch, an algorithm for detecting a transition sequence, the algorithm parameterized from a set of predetermined, fixed data indicative of a transition sequence; acquiring a set of variable data using a sensor including an accelerometer for measuring variable data on the acceleration of the watch in three directions, and/or a gyroscope for measuring variable data on the position of the watch in three directions; processing the variable data using the algorithm to obtain a concordance value of the set of processed variable data; and, if the resulting concordance value is higher than a threshold, triggering the exit of the dial having the digital display from standby mode.

Claims

1. A method for managing an operation for a watch to exit standby mode, said watch being provided with a dial having a digital display, and being placed into a standby mode in which the dial is off, said method comprising:

storing, in a memory module of the watch, at least one algorithm for detecting a transition sequence, said algorithm having been parameterized from a set of predetermined, fixed data indicative of a transition sequence;

acquiring a set of variable data using a sensor assembly, said sensor assembly including an accelerometer capable of measuring variable data on the acceleration of the watch in three directions, and a gyroscope capable of measuring variable data on the position of the watch in three directions;

processing the set of variable data using the algorithm for detecting a transition sequence in order to obtain a concordance value of the set of processed variable data;

if the resulting concordance value is higher than a predetermined threshold, triggering the exit of the dial having the digital display from standby mode,

wherein the algorithm has been subject to a learning phase to adapt a decision model to the algorithm.

2. The method according to claim 1, wherein the set of variable data is acquired over a predetermined duration, comprised between 0.15 seconds and 3 seconds.

3. The method according to claim 2, wherein the predetermined duration is 2 seconds.

4. The method according to claim 1, wherein the set of variable data is acquired by taking measures using the sensor assembly at a frequency comprised between ten and fifty hertz.

5. The method according to claim 4, wherein the frequency is twenty hertz.

6. The method according to claim 1, wherein the set of variable data is acquired continuously using an intermediate processor, of dedicated DSP type, of the watch, said intermediate processor being maintained in an active state.

7. The method according to claim 6, wherein exiting from standby of the dial with digital display is triggered following an exit from standby of a main processor of the watch, said exit from standby of the main processor being triggered by the reception of a signal, wherein said signal is transmitted if the resulting concordance value is higher than a predetermined threshold.

8. The method according to claim 7, wherein said exit from standby of the main processor is triggered by an interruption signal transmitted from the intermediate processor to the main processor.

9. The method according to claim 1, comprising measuring, using a light sensor present on the watch, a luminosity information, wherein the exit of the dial having the digital display from standby mode is conditioned to the presence of a minimal luminosity threshold.

10. A watch capable of implementing the method according to claim 1.

11. The method according to claim 1, wherein the decision model is based upon a decision tree, a neuron network or a logistic regression.

12. The method according to claim 1, wherein the transition sequence is associated with an observed movement of the watch.

13. A method for managing an operation for a watch to exit standby mode, said watch being provided with a dial having a digital display, and being placed into a standby mode in which the dial is off, said method comprising:

storing, in a memory module of the watch, at least one algorithm for detecting a transition sequence, said algorithm having been parameterized from a set of predetermined, fixed data indicative of a transition sequence;

acquiring a set of variable data using a sensor assembly, said sensor assembly including an accelerometer capable of measuring variable data on the acceleration of the watch in three directions, and a gyroscope capable of measuring variable data on the position of the watch in three directions;

processing the set of variable data using the algorithm for detecting a transition sequence in order to obtain a concordance value of the set of processed variable data;

if the resulting concordance value is higher than a predetermined threshold, triggering the exit of the dial having the digital display from standby mode,

wherein the acquiring comprises;

measuring a first group of variable data using the gyroscope and the accelerometer;

calculating a set of additional variation data from the first group of variable data to constitute a second group of variable data;

combining data from the first group of variable data and data from the second group of variable data to constitute the set of variable data.

14. A method for managing an operation for a watch to exit standby mode, said watch being provided with a dial having a digital display, and being placed into a standby mode in which the dial is off, said method comprising:

storing, in a memory module of the watch, at least one algorithm for detecting a transition sequence, said algorithm having been parameterized from a set of predetermined, fixed data indicative of a transition sequence;

acquiring a set of variable data using a sensor assembly, said sensor assembly including an accelerometer capable of measuring variable data on the acceleration of the watch in three directions, and a gyroscope capable of measuring variable data on the position of the watch in three directions;

processing the set of variable data using the algorithm for detecting a transition sequence in order to obtain a concordance value of the set of processed variable data;

if the resulting concordance value is higher than a predetermined threshold, triggering the exit of the dial having the digital display from standby mode, and

measuring, using a light sensor present on the watch, a luminosity information, wherein the exit of the dial having the digital display from standby mode is conditioned to the presence of a minimal luminosity threshold,

wherein each transition sequence is associated with an observed movement of the watch, wherein first specific transition sequences are provided in a hypothesis where the watch is worn on a left wrist, and second specific transition sequences are provided in the hypothesis where the watch is worn on a right wrist.
