Abstract

A wearable ring for a human user, the device includes an interior loop of the ring, an exterior loop of the ring surrounding the interior loop, an interior space between the interior loop and the exterior loop. Disposed within the ring are a plurality of sensors arranged within the interior space at predetermined intervals along a circumference of the ring, such that when the exterior loop is moved closer to the interior loop at a particular point along the circumference of the ring through interaction with the exterior loop, a change detected by at least one of the sensors identifies an area near the particular point as an interaction with the ring.

Claims (53)

1 . A wearable device comprising:

an interior loop of the wearable device;

an exterior loop of the wearable device surrounding the interior loop;

an interior space between the interior loop and the exterior loop;

two sensors arranged within the interior space at predetermined intervals, such that:

a first sensor of the two sensors is arranged in a position along the circumference within the interior space; and

a second sensor of the two sensors is arranged at a position of a known number of degrees along the circumference from the first sensor within the interior space;

quadrature sensing enables the use of the first and second sensors to detect the area near the particular point at which pressure is applied to any portion of the exterior loop when the two sensors are arranged ninety degrees apart along the circumference; and

when the exterior loop is moved closer to the interior loop at a particular point along the circumference of the exterior loop, the movement of the exterior loop closer to the interior loop is detected by at least one of the sensors at an area near the particular point, the particular point associated with a specific function.

2 . The wearable device of claim 1 further comprising:

one or more processors and associated memory; and

at least one communications interface for communicating with other computing devices.

3 . The wearable device of claim 1 wherein the two sensors are capacitive sensors and a change in capacitance is directly proportional to an amount the exterior loop is moved toward the interior loop at the particular point.

4 . The wearable device of claim 3 wherein the interior space at least partially filled with a non-conductive material and wherein the non-conductive material includes at least one material selected from the group comprising: non-conductive fluid, rubber, air, oxygen, nitrogen, and a plurality of compression springs of a non-conductive material.

5 . The wearable device of claim 1 wherein the two sensors are strain gauges.

6 . The wearable device of claim 1 wherein:

when the exterior loop is moved closer to the interior loop along a path beginning at the particular point along the circumference of the exterior loop and continuing along a path to a second particular point in a direction along the exterior loop, the path and the direction are detected by at least one of the two sensors.

7 . A wearable ring, the ring comprising:

an interior loop of the ring;

an exterior loop of the ring surrounding the interior loop;

an interior space between the interior loop and the exterior loop;

two sensors arranged within the interior space at predetermined intervals along a circumference of the ring, such that:

a first sensor of the two sensors is arranged in a position along the circumference within the interior space; and

a second sensor of the two sensors is arranged at a position of a known number of degrees along the circumference from the first sensor within the interior space;

quadrature sensing enables the use of the first and second sensors to detect variations in respective first and second capacitance to thereby derive the area near the particular point when the two sensors are arranged ninety degrees apart along the circumference

when the exterior loop is moved closer to the interior loop at a particular point along the circumference of the ring through interaction with the exterior loop, the movement is detected by at least one of the sensors changes, identifying an area near the particular point as an interaction with the ring, the particular point associated with a specific function; and

the area near the particular point differentiable from other points along the circumference is associated with a particular action for execution and other actions for execution are associated with the other points along the circumference; and

wherein the two sensors are capacitive sensors and a change in capacitance is directly proportional to an amount the exterior loop is moved toward the interior loop at the particular point such that when a capacitance detected exceeds a first predetermined threshold, it is associated with a first action for execution and when the capacitance detected exceeds a second predetermined threshold, it is associated with a second action.

8 . The wearable device of claim 6 further comprising:

one or more processors and associated memory; and

at least one communications interface for communicating with other computing devices.

9 . The wearable ring of claim 7 wherein the capacitance is identified as associated with the area near the particular point as differentiable from other points along the circumference.

10 . The wearable ring of claim 7 wherein when the exterior loop is moved relative to the interior loop at the particular point along the circumference of the exterior loop, a second capacitance detected by the second sensor increases or decreases thereby enabling a processor associated with the ring to derive a location along the circumference of the ring of the area near the particular point.

11 . The wearable ring of claim 7 wherein:

when the exterior loop is moved closer to the interior loop along a path beginning at the particular point along the circumference of the exterior loop and continuing along a path to a second particular point in a direction along the exterior loop, the path and the direction detected by at least one of the two sensors.

12 . A wearable ring, the ring comprising:

an interior loop of the ring;

an exterior loop of the ring surrounding the interior loop;

a second capacitive sensor of a plurality of sensors is arranged at a position of a known number of degrees along the circumference within the interior space;

the plurality of sensors arranged such that quadrature sensing enables the first and second capacitive sensors to detect variations in respective a first and second capacitance when the exterior loop is moved relative to the interior loop at a particular point to derive the area near the particular point thereby enabling a processor associated with the ring to derive a location along the circumference of the ring of the area near the particular point.

13 . The wearable ring of claim 12 wherein the area near the particular point is differentiable from other points along the circumference and is associated with a particular action for execution and other actions for execution are associated with the other points along the circumference.

14 . The wearable ring of claim 12 wherein a first and second capacitance detected is directly proportional to an amount the exterior loop is moved toward the interior loop at the particular point.

15 . The wearable ring of claim 12 wherein when the capacitance detected exceeds a first predetermined threshold, it is associated with a first action for execution and when the capacitance detected exceeds a second predetermined threshold, it is associated with a second action.

16 . A wearable device comprising:

an interior loop of the wearable device;

an exterior loop of the wearable device surrounding the interior loop;

an interior space between the interior loop and the exterior loop;
