Electronic device for collecting finger data and displaying a finger movement trace and related methods
View Patent ↗An electronic device may include a finger sensor, a display, and a controller coupled to the finger sensor and the display. The controller may be configured to collect finger data from multiple portions of a user's finger as the user's finger is moved around on the finger sensor along a finger travel path. The controller may also be configured to generate on the display a finger movement trace corresponding to the finger movement travel path.
1. An electronic device comprising:
a finger sensor;
a display; and
a controller coupled to said finger sensor and said display, and capable of
collecting finger data as a user's finger is moved around on said finger sensor along a finger movement travel path,
generating on said display a coating image, and
generating on said display a finger movement trace corresponding to the finger movement travel path and a virtual scratch-off of the coating image.
2. The electronic device according to claim 1 , wherein said controller is capable of generating the finger movement trace in real time.
3. The electronic device according to claim 1 , further comprising a database for storing finger data; and wherein said controller is capable of determining a match between the collected finger data and finger data stored in said database.
4. The electronic device according to claim 3 , wherein said controller is capable of clearing the finger movement trace from said display based upon the match.
5. The electronic device according to claim 3 , wherein said controller is capable of enrolling the collected finger data in said database based upon there being no match.
6. The electronic device according to claim 1 , wherein said controller is capable of clearing the finger movement trace from said display based upon a threshold amount of collected finger data.
7. The electronic device according to claim 1 , wherein said controller is capable of displaying a notification on said display based upon a threshold amount of collected finger data.
8. The electronic device according to claim 1 , wherein said controller is capable of processing the collected finger data and generating a finger image based thereon.
9. The electronic device according to claim 1 , wherein said finger sensor has a sensing area smaller than a user's finger.
10. The electronic device according to claim 1 , wherein said controller is capable of generating the finger movement trace to correspond to a finger movement travel path having at least one finger direction change while the user's finger is continuously maintained on the finger sensing area.
11. A method of collecting finger data in an electronic device comprising a finger sensor and a display, the method comprising:
collecting finger data as a user's finger is moved around on the finger sensor along a finger movement travel path;
generating on the display a coating image; and
generating on the display a finger movement trace corresponding to the finger movement travel path and a virtual scratch-off of the coating image.
12. The method according to claim 11 , wherein the finger movement trace is generated on the display in real time.
13. The method according to claim 11 , further comprising determining a match between the collected finger data and finger data stored in a database.
14. The method according to claim 13 , further comprising clearing the finger movement trace from the display based upon the match.
15. The method according to claim 13 , further comprising enrolling the collected finger data in the database based upon there being no match.
16. The method according to claim 11 , wherein the finger movement trace is generated to correspond to a finger movement travel path having at least one finger direction change while the user's finger is continuously maintained on the finger sensing area.
17. The method according to claim 11 , wherein the electronic device further comprises a controller coupled to the finger sensor and display; and wherein collecting finger data, generating the coating image, and generating the finger movement trace comprises operating the controller to perform each in cooperation with the finger sensor and display.
18. An electronic device comprising:
a finger sensor;
a display; and
a controller coupled to said finger sensor and said display, and capable of
collecting finger data as a user's finger is moved around on said finger sensor along a finger movement travel path,
generating on said display a finger movement trace corresponding to the finger movement travel path, and
generating on said display a plurality of spaced apart finger trace target points for connection via the finger movement trace.
19. The electronic device according to claim 18 , wherein said controller is capable of generating the finger movement trace in real time.
20. The electronic device according to claim 18 , further comprising a database for storing finger data; and wherein said controller is capable of determining a match between the collected finger data and finger data stored in said database.
21. The electronic device according to claim 20 , wherein said controller is capable of clearing the finger movement trace from said display based upon the match.
22. The electronic device according to claim 20 , wherein said controller is capable of enrolling the collected finger data in said database based upon there being no match.
23. A method of collecting finger data in an electronic device comprising a finger sensor and a display, the method comprising:
collecting finger data as a user's finger is moved around on the finger sensor along a finger movement travel path;
generating on the display a finger movement trace corresponding to the finger movement travel path; and
generating on the display a plurality of spaced apart finger trace target points for connection via the finger movement trace.
24. The method according to claim 23 , wherein the finger movement trace is generated on the display in real time.
25. The method according to claim 23 , further comprising determining a match between the collected finger data and finger data stored in a database.
26. The method according to claim 25 , further comprising clearing the finger movement trace from the display based upon the match.
27. The method according to claim 25 , further comprising enrolling the collected finger data in the database based upon there being no match.
28. The method according to claim 23 , wherein the finger movement trace is generated to correspond to a finger movement travel path having at least one finger direction change while the user's finger is continuously maintained on the finger sensing area.
29. The method according to claim 23 , wherein the electronic device further comprises a controller coupled to the finger sensor and display; and wherein collecting finger data, generating the finger movement trace, and generating the spaced apart finger trace target points comprises operating the controller to perform each in cooperation with the finger sensor and display.
