Abstract

Accelerometer-based orientation and/or movement detection for controlling wearable devices, such as wrist-worn audio recorders and wristwatches. A wrist-worn audio recorder can use an accelerometer to detect the orientation and/or movement of a user'"'"'s wrist and subsequently activate a corresponding audio-recorder function, for instance recording or playback. A wearable device with a vibration mechanism can use this method to remind a user of an undesirable movement such as restless leg movement. Likewise, a talking wristwatch can use this method to activate audio reporting of time when a user moves or orients his or her wrist in close proximity to his or her ear. In such applications, and many others, accelerometer-based control of the wearable device offers significant advantages over conventional means of control, particularly in terms of ease of use and durability.

Claims

1. A method for activating an audio-recorder function of a wearable device, comprising:

(a) acquiring acceleration data of a wearable device; and

(b) using said acceleration data to activate an audio-recorder function of said wearable device.

2. The method according to claim 1 wherein the step of using said acceleration data to activate an audio-recorder function of said wearable device comprises using said acceleration data to compute an orientation of said wearable device to activate an audio-recorder function when said orientation is a predetermined orientation.

3. The method according to claim 2 wherein said audio-recorder function is audio recording, and said predetermined orientation is an orientation of said wearable device in front of the mouth of a user who wears said wearable device on a wrist.

4. The method according to claim 2 wherein said audio-recorder function is playback of recorded audio data, and said predetermined orientation is an orientation of said wearable device in predetermined proximity of a ear of a user who wears said wearable device.

5. The method according to claim 1 wherein the step of using said acceleration data to activate an audio-recorder function of said wearable device comprises using said acceleration data to compute a movement of said wearable device to activate an audio-recorder function when said movement is a predetermined movement.

6. The method according to claim 1 wherein the step of using said acceleration data to activate an audio-recorder function of said wearable device comprises using said acceleration data to compute an orientation and a movement of said wearable device to activate an audio-recorder function when said orientation is a predetermined orientation and said movement is a predetermined movement.

7. The method according to claim 6 wherein said audio-recorder function is audio recording, said predetermined orientation is an orientation of said wearable device in front of the mouth of a user who wears said wearable device on a wrist, and said predetermined movement is a natural movement of said user'"'"'s wrist wearing said wearable device for said user to move said wearable device to said predetermined orientation in front of the mouth of said user.

8. The method according to claim 6 wherein said audio-recorder function is playback of recorded audio data, said predetermined orientation is an orientation of said wearable device in predetermined proximity of a ear of a user who wears said wearable device on a wrist, and said predetermined movement is a natural movement of said user'"'"'s wrist wearing said wearable device for said user to move said wearable device to said predetermined orientation of said wearable device in predetermined proximity of said ear of said user.

9. A wearable device, comprising:

(a) a wearable audio recorder;

(b) a three-axis accelerometer for acquiring acceleration data of said wearable audio recorder; and

(c) a detection means for using said acceleration data to activate an audio-recorder function of said wearable audio recorder.

10. The wearable device according to claim 9 wherein said detection means comprises a means for using said acceleration data to compute an orientation of said wearable audio recorder to activate an audio-recorder function when said orientation is a predetermined orientation.

11. The wearable device according to claim 9 wherein said detection means comprises a means for using said acceleration data to compute a movement of said wearable audio recorder to activate an audio-recorder function when said movement is a predetermined movement.

12. The wearable device according to claim 9 wherein said detection means comprises a means for using said acceleration data to compute an orientation and a movement of said wearable audio recorder to activate an audio-recorder function when said orientation is a predetermined orientation and said movement is a predetermined movement.

14. The wearable device according to claim 9 wherein said detection means comprises a means for using said acceleration data to compute a movement of said wearable audio recorder to activate playing back of a reminding audio message after said movement matches a predetermined movement a predetermined number of times.

15. The wearable device according to claim 14 wherein said detection means further comprises a vibration mechanism, which vibrates said wearable audio recorder for reminding a user who wears said wearable audio recorder after said movement matches said predetermined movement said predetermined number of times.

16. A talking wristwatch, comprising:

(a) a wristwatch;

(b) an accelerometer for acquiring acceleration data of said wristwatch; and

(c) a detection means for using said acceleration data to activate audio time reporting of said wristwatch.
