Abstract
An electronic device includes a housing and a finger sensor carried by the housing to receive a fingerprint area of a user's finger adjacent thereto. A processor can be carried by the housing and connected to the finger sensor. The processor determines a plurality of finger motion patterns of the fingerprint area of the user's finger relative to the finger sensor. The processor also matches the determined finger motion patterns to stored finger motion patterns of respective characters, and may display the characters as text on a display. The finger sensor may also be used to verify the user based upon a fingerprint, for example.
Claims43
An electronic device comprising:
- a housing;
- a finger sensor carried by said housing to receive a fingerprint area of a user's finger adjacent thereto;
- a display carried by said housing;
- and
- a processor carried by said housing and connected to said finger sensor and said display, said processor for
- determining a plurality of finger motion patterns of the fingerprint area of the user's finger relative to said finger sensor,
- matching the finger motion patterns to stored finger motion patterns for respective characters, and
- generating text on said display based upon the characters.
An electronic device comprising:
- a housing;
- a finger image sensor carried by said housing to receive a fingerprint area of a user's finger adjacent thereto, said fingerprint image sensor comprising a substrate and an array of fingerprint sensing pixels on said substrate;
- and
- a processor carried by said housing and connected to said finger image sensor for
- determining a plurality of finger motion patterns of the fingerprint area of the user's finger relative to said finger sensor, and
- matching the finger motion patterns to stored finger motion patterns for respective characters.
An electronic device comprising:
- a housing;
- a finger sensor carried by said housing to receive a fingerprint area of a user's finger adjacent thereto;
- and
- a processor carried by said housing and connected to said finger sensor for
- determining a plurality of finger motion patterns of the fingerprint area of the user's finger relative to said finger sensor, at least one finger motion pattern comprising a finger rotational motion, and
- matching the finger motion patterns to stored finger motion patterns for respective characters.
A method of using an electronic device comprising a display, and a finger sensor to receive a fingerprint area of a user's finger adjacent thereto, the method comprising:
- determining a plurality of finger motion patterns of the fingerprint area of the user's finger relative to the finger sensor;
- matching the determined finger motion patterns to stored finger motion patterns for respective characters;
- and
- generating text on the display based upon the characters.
