[0050] Accordingly the embodiments herein provide a wearable device with a bezel ring to enable motion in multiple degrees of freedom. The wearable device includes a bezel ring with a plurality of holes at a uniform distance along a circumference of the bezel ring for placement of a plurality of magnets. The wearable device includes a watch dial with an outer periphery having a plurality of holes at a uniform distance for placement of a plurality of springs and an inner periphery to house inertial sensors at a pre-determined position. The wearable device includes a flexible ring placed in between an inner surface of the bezel ring and the watch dial and the plurality of springs are placed within the plurality of holes of the outer periphery of the watch dial. The bezel ring is adapted to support at least one of tilting, shifting and rotation over the watch dial.
[0051] In an embodiment, the bezel ring surrounds the watch dial with a pre-determined gap between the bezel ring and the watch dial to enable tilting and shifting of the bezel ring over the watch dial.
[0052] In an embodiment, the bezel ring is mounted over the watch dial with a pre-determined gap between the bezel ring and the watch dial.
[0053] In an embodiment, the plurality of springs on the outer periphery of the watch dial enables tilting of the bezel ring over the watch dial.
[0054] In an embodiment, the flexible ring placed in between the bezel ring and the watch dial enables the bezel ring to shift over the watch dial.
[0055] In an embodiment, the inertial sensors placed on the inner periphery of the watch dial detect a change in magnetic field based on movement of the plurality of magnets in the bezel ring during at least one of tilting and shifting of the bezel ring over the watch dial.
[0056] In an embodiment, a plurality of sensors are placed along the inner periphery of the watch dial to detect a change in a capacitance based on a movement of the bezel ring during at least one of tilting and shifting of the bezel ring over the watch dial.
[0057] The proposed wearable device allows the bezel ring to enable motion in multiple degrees of freedom. The design of the circular bezel ring enables the multiple degrees of freedom which includes tilting, shifting and rotation. It should be noted that the bezel can be tilted, shifted and rotated over the watch dial and based on titling, shifting and rotation, one or more actions are performed on the wearable device. Thus, the proposed wearable device with the bezel ring allows the user to interact with the wearable device by performing tilting, shifting and rotation of the bezel ring to provide one or more inputs to the wearable device. The wearable device performs one or more actions in accordance with the one or more inputs (i.e., tilting, shifting and rotation) on the bezel ring.
[0058] The bezel ring can be tilted or shifted over the watch dial in any direction (i.e., horizontal or vertical or degree of tilt/shift). The bezel ring can be shifted and rotated simultaneously over the watch dial. Further, the bezel ring can be tilted and rotated simultaneously.
[0059] In various embodiments, a change in magnetic field due to the movement of permanent magnets in the bezel ring is detected by the inertial sensors housed in the inner periphery of the watch dial. In an example, the bezel ring is embedded with eight magnets at 45 degree interval. The change in the magnetic field is detected by the two inertial sensors (i.e., magnetometers placed within the watch dial. With a single magnetometer, similar functionalities can be obtained but the system requires stronger magnet which is not feasible on the wearable device. Thus, two magnetometers are placed closer to the bezel to improve the detection accuracy. The magnetometer output contains the ambient magnetic field of the earth which changes based on the orientation of the device. The baseline value is updated when the device is not undergoing any bezel event. For detection of the change in magnetic field, the relative change from the baseline value is used as a feature to identify events on the bezel ring.
[0060] In various embodiments, the wearable device is equipped with capacitive sensors over the watch dial. This design is based on the principle of detecting the change in the capacitance based on movement of the bezel ring. The bezel ring includes patches of conductive strips on its bottom side to detect tilting. The watch dial has as an arrangement of electrodes around it to detect shifting.
[0061] The bezel ring will be floating on the top edge of the watch with the help of compression springs on the bottom. The uniform distribution of the eight (8) compression springs allows the bezel ring to tilt in any direction. The flexible ring (for example, a Delrin ring) placed in between the bezel ring and watch dial allows shifting and tilting of the bezel. Each spring supports a ball that creates the detent effect required for rotate motion. Each spring includes a spherical ball which will be in contact with the bottom surface of the bezel ring. Further, the bezel ring has 24 oblong grooves at regular intervals on the bottom side, to create the detent feedback when rotating.
[0062] In an embodiment, the spherical ball allows a frictionless movement while rotating the bezel ring and it also limits the bezel ring from freely rotating. The groves on the bottom side of the bezel ring are in oval shape to allow horizontal shifting of the bezel ring.

[0082]
[0083]
[0084]
[0085] When the bezel ring 102 is tilted either left or right, the angle 0 changes to 1 and 2 respectively (i.e., 1>0>2)
[0086] Thus, due to the shifting and/or tilting of the bezel ring over the watch dial 104, there is a change in magnetic field due to the variation of distance due to shifting and angular variation due to tilting. The magnetometers detect the change in magnetic field due to the shifting and/or tilting of the bezel ring 102 over the watch dial 104. The magnetometer output contains the ambient magnetic field of the earth which changes based on the orientation of the wearable device 100. In an embodiment, the baseline value is updated when the wearable device 100 device is not undergoing any event on the bezel ring 102. For detection of the change in magnetic field, the relative change from the baseline value is used as a feature to identify events (tilting, shifting and rotation) on the bezel ring 102.
[0087]
[0088] Prior to detecting a change in magnetic field, the change of magnetic field due to earth magnet is dynamically handled at the wearable device 100.
[0089] At step 1202, the method includes detecting a change in magnetic field through the inertial sensors in response to the input received on the bezel ring 102. The inertial sensors (i.e., the magnetometers) positioned on the inner periphery 104b of the watch dial 104 detect the change in magnetic field based on the input received on the bezel ring 102.
[0090] At step 1204, the method includes determining that the change in magnetic field is greater than a pre-defined threshold value. The change in magnetic field is compared with a threshold value to determine whether the change in magnetic field is greater than the threshold value.
[0091] In an embodiment, the threshold value is dynamically changed in response to ambient magnetic field.
[0092] At step 1206, the method includes identifying the input received on the bezel ring in response to determining that the change in the magnetic field is greater than the threshold value. When there is a change in magnetic field, the relative change from the baseline value of the magnetic field is used as a feature to identify the input events (tilting, shifting and rotation) on the bezel ring 102. As the magnetometer measurement is affected by the earth's magnetic field, the baseline value is continuously updated unless there is a change that corresponds to the action on the bezel ring 102. The resetting of the baseline also ensures that the system works for different orientations of the user's arm.
[0093] At step 1208, the method includes performing one or more actions on the wearable device 100 in accordance with the input. The wearable device 100 performs various actions tilting, shifting and rotation) on the bezel ring 102.
[0094] The proposed design of the bezel ring 102 can be used for performing various actions on the wearable device 100. For e.g. controlling core application on the watch, flying drone and so on. The Table 1 shows an example mapping of the input events on the bezel ring 102 with respect to an action inside the application running on the wearable device 100 or a connected device to the wearable device 100.
