Abstract

There is provided a physiological detection device including a finger detection unit, a storage unit and a processing unit. The finger detection unit is configured to detect a current track drawn by a current user and current physiological information of the current user. The storage unit is configured to previously store track features of predetermined tracks drawn, for a predetermined time interval or a predetermined times on the finger detection unit, by a plurality of users and each of the track features is associated with one of the users. The processing unit is configured to analyze the current track and identify the current user according to the track features in the storage unit. There is further provided a physiological detection method and a user identification method.

Claims

1. A user identification method, comprising:

a step of constructing database in which at least one predetermined track, drawn by at least one user for a predetermined time interval or a predetermined times on a finger detection unit, is analyzed to construct a database containing at least one track feature corresponding to the at least one predetermined track drawn by the at least one user; and

a step of identifying user in which a current track drawn by a current user on the finger detection unit is analyzed and the current user is identified according to the track feature in the database;

wherein after the step of identifying user ID the method further comprises;

detecting current physiological information of the current user with the finger detection unit; and

storing the current physiological information to the database.

2. The user identification method as claimed in claim 1, wherein the track feature comprises track angle information and track length information.

3. The user identification method as claimed in claim 2, wherein in the step of identifying user, a distribution shape of the track angle information and the track length information is compared with a track angle distribution and a track length distribution of the current track.

4. The user identification method as claimed in claim 1, wherein after the step of identifying user the method further comprises:

linking to pass physiological information of the current user in the database.

5. The user identification method as claimed in claim 1, wherein the predetermined track is a circle, a rectangle, a polygon or a line segment.

6. A physiological detection device, comprising:

a finger detection unit configured to detect a current track drawn by a current user and current physiological information of the current user;

a storage unit configured to previously store track features of predetermined tracks drawn, for a predetermined time interval or a predetermined times on the finger detection unit, by a plurality of users and each of the track features is associated with one of the users; and

a processing unit configured to analyze the current track and identify the current user according to the track features in the storage unit.

7. The physiological detection device as claimed in claim 6, wherein the current physiological feature comprises at least one of a blood oxygenation and a heart rate.

8. The physiological detection device as claimed in claim 6, wherein the finger detection unit is an optical finger mouse.

9. The physiological detection device as claimed in claim 6, wherein the track feature comprises track angle information and track length information.

10. The physiological detection device as claimed in claim 9, wherein the processing unit compares a distribution shape of the track angle information and the track length information with a track angle distribution and a track length distribution of the current track so as to identify the current user.

11. The physiological detection device as claimed in claim 6, wherein the predetermined track is a circle, a rectangle, a polygon or a line segment.

12. A physiological detection method, comprising:

detecting a current track drawn by a user with a finger detection unit;

comparing, using a processing unit, the current track with a track feature previously stored;

linking, using the processing unit, to pass physiological information associated with the user; and

detecting current physiological information of the user with the finger detection unit.

13. The physiological detection method as claimed in claim 12, further comprising:

storing the current physiological information as a part of the pass physiological information.

14. The physiological detection method as claimed in claim 12, wherein the pass physiological information and the current physiological information comprise at least one of a blood oxygenation and a heart rate.

15. The physiological detection method as claimed in claim 12, wherein the track feature comprises track angle information and track length information.

16. The physiological detection method as claimed in claim 15, wherein in the step of comparing the current track with a track feature, the processing unit compares a distribution shape of the track angle information and the track length information with a track angle distribution and a track length distribution of the current track.

17. The physiological detection method as claimed in claim 12, wherein the predetermined track is a circle, a rectangle, a polygon or a line segment.
