Abstract
A method can include acquiring sensor data via a sensor for a fingertip in contact with a surface; identifying a finger of the fingertip based on the sensor data and stored data, where the identifying identifies the finger as one of at least two different fingers of a hand; pairing the identified finger with the surface to determine a finger and surface pair; comparing the finger and surface pair to a reference pair; and, based on the comparing, issuing a signal.
Claims14
A method comprising:
- acquiring sensor data via a sensor for a fingertip in contact with a surface;
- identifying a finger of the fingertip based on the sensor data and stored data, wherein the identifying identifies the finger as one of at least two different fingers of a hand;
- pairing the identified finger with the surface to determine a finger and surface pair;
- comparing the finger and surface pair to a reference pair;
- and
- based on the comparing, issuing a signal, wherein the surface comprises a surface of a key of a keyboard and wherein the comparing fails to match the finger and surface pair to the reference pair, the signal indicates improper touch-typing.
3 more elements
A device comprising:
- a processor;
- memory accessible to the processor;
- a sensor that acquires sensor data for a fingertip in contact with a surface;
- processor-executable instructions stored in the memory and executable by the processor to instruct the device to:
- identify a finger of the fingertip based on the sensor data and stored data, wherein an identification identifies the finger as one of at least two different fingers of a hand;
- pair the identified finger with the surface to determine a finger and surface pair;
- perform a comparison of the finger and surface pair to a reference pair;
- and
- issue a signal based on the comparison, wherein the surface comprises a surface of a key of a keyboard and wherein the comparison fails to match the finger and surface pair to the reference pair, the signal indicates improper touch-typing.
