Abstract

A method, apparatus and computer program product are provided to facilitate user input based upon the relative position of their fingers. In the context of a method, sensor information is received that is indicative of the position of a first finger relative to a second finger. The first finger may be a thumb such that the sensor information is indicative of the position of the thumb relative to the second finger. In conjunction with the receipt of sensor information, the method receives sensor information from a sensor that is offset from an interface between the first and second fingers so as not to be positioned between the first and second fingers. The method also determines, with a processor, the relative position of the first and second fingers based upon the sensor information and causes performance of an operation in response to the relative position of the first and second fingers.

Claims

receiving sensor information indicative of a position of a first finger relative to a second finger, wherein receiving sensor information comprises receiving sensor information from a sensor that is offset from an interface between the first and second fingers so as not to be positioned between the first and second fingers;

determining, with a processor, the position of the first finger relative to the second finger based upon the sensor information; and

causing performance of an operation in response to the position of the first finger relative to the second finger.

2. A method according to claim 1 wherein the first finger is a thumb such that the sensor information is indicative of the position of the thumb relative to the second finger.

3. A method according to claim 1 wherein receiving the sensor information comprises receiving sensor information from a magnetometer carried by one of the first and second fingers indicative of the position of the magnetometer relative to a magnet carried by the other one of the first and second fingers, and wherein determining the position of the first finger relative to the second finger comprises determining the position of the first finger relative to the second finger in at least one dimension.

4. A method according to claim 1 wherein receiving the sensor information comprises receiving sensor information from first and second magnetometers carried by one of the first and second fingers indicative of the position of the first and second magnetometers relative to a magnet carried by the other one of the first and second fingers, and wherein determining the position of the first finger relative to the second finger comprises determining the position of the first finger relative to the second finger in at least two dimensions.

5. A method according to claim 4 wherein the first and second magnetometers are carried by one of the first and second fingers so as to have a predefined offset therebetween.

6. A method according to claim 1 further comprising determining a direction of movement of the first finger across the second finger based upon the position of the first finger relative to the second finger at two or more instances, and wherein causing performance of the operation comprises causing performance of the operation in response to the direction of movement of the first finger across the second finger.

7. A method according to claim 1 wherein receiving the sensor information comprises receiving sensor information from first and second magnetometers carried by the first and second fingers, respectively, indicative of the position of the first and second magnetometers within an electromagnetic field, and wherein determining the position of the first finger relative to the second finger comprises determining the position of the first finger relative to the second fingerin at least two dimensions.

8. A method according to claim 1 wherein a textured surface is carried by at least one of the first and second fingers, and wherein receiving the sensor information comprises receiving sensor information from a vibration or acoustic sensor indicative of movement of one of the first and second fingers across the textured surface.

9. An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the processor, cause the apparatus to at least:

receive sensor information indicative of a position of a first finger relative to a second finger by receiving sensor information from a sensor that is offset from an interface between the first and second fingers so as not to be positioned between the first and second fingers;

determine a position of the first finger relative to the second fingerbased upon the sensor information; and

cause performance of an operation in response to the position of the first finger relative to the second finger.

10. An apparatus according to claim 9 wherein the first finger is a thumb such that the sensor information is indicative of the position of the thumb relative to the second finger.

11. An apparatus according to claim 9 wherein the at least one memory and the computer program code are configured to, with the processor, cause the apparatus to receive the sensor information by receiving sensor information from a magnetometer carried by one of the first and second fingers indicative of the position of the magnetometer relative to a magnet carried by the other one of the first and second fingers, and wherein the at least one memory and the computer program code are configured to, with the processor, cause the apparatus to determine the position of the first finger relative to the second fingerby determining the position of the first finger relative to the second fingerin at least one dimension.

12. An apparatus according to claim 9 wherein the at least one memory and the computer program code are configured to, with the processor, cause the apparatus to receive the sensor information by receiving sensor information from first and second magnetometers carried by one of the first and second fingers indicative of the position of the first and second magnetometers relative to a magnet carried by the other one of the first and second fingers, and wherein the at least one memory and the computer program code are configured to, with the processor, cause the apparatus to determine the position of the first finger relative to the second fingerby determining the position of the first finger relative to the second finger in at least two dimensions.

13. An apparatus according to claim 12 wherein the first and second magnetometers are carried by one of the first and second fingers so as to have a predefined offset therebetween.

14. An apparatus according to claim 9 wherein the at least one memory and the computer program code are further configured to, with the processor, cause the apparatus to determine a direction of movement of the first finger across the second finger based upon the position of the first finger relative to the second finger at two or more instances, and wherein the at least one memory and the computer program code are configured to, with the processor, cause the apparatus to cause performance of the operation by causing performance of the operation in response to the direction of movement of the first finger across the second finger.

15.
