BACKGROUND OF INVENTION

Smart rings have become increasingly popular in recent years due to their convenience and portability. These small devices can perform a range of functions, from tracking fitness and health data to making payments and controlling smart home devices. However, the small size of smart rings has posed a significant challenge in terms of designing effective user interfaces. While larger wearable devices such as smartwatches can incorporate touchscreens, buttons, and other user interface elements, these options are often unsuitable for smart rings due to their size constraints.

To address this challenge, designers and engineers have been exploring alternative user interface mechanisms that can be incorporated into smart ring designs. Some of these mechanisms include voice commands, gesture recognition, and haptic feedback. Voice commands allow users to control their smart rings using spoken commands, while gesture recognition enables users to control their devices using hand movements. Haptic feedback, on the other hand, provides physical feedback to users through vibrations or other sensory cues.

Despite these innovative solutions, there is still a need for a compact yet user-friendly interface mechanism that can be seamlessly integrated into smart ring designs. This is particularly important as the scope of features that can be offered to users in this form factor is largely dependent on the effectiveness of the user interface. As such, designers and engineers must continue to explore new and innovative ways to incorporate user interfaces into smart rings, ensuring that these devices remain both functional and user-friendly.

It is desired to address the above-mentioned disadvantages or other shortcomings or at least provide a useful alternative.

FIG. 2C is a schematic figure that illustrates a static component of the wearable ring device, according to the embodiments disclosed herein.

The static component (105) includes the sensing elements (111) which detects the position or the angle of the rotatable interface (103) relative to the static component (105). The sensing elements (111) sends the input signal to the microcontroller (115) indicating the contact with the notch (109) with respect to the sensing elements (111). The sensing elements (111) can include but are not limited to the capacitive sensor, the inductive sensor, the optical sensor, the pressure sensor, and the hall sensor. Each of these sensors has its own unique advantages and disadvantages, and the choice of sensor will depend on the specific requirements of the application.

In particular, the capacitive sensor is a highly effective sensor for detecting the position of the notch (109) during the rotation of the rotatable interface (103). This sensor works by detecting changes in capacitance as the conductive notch (109) moves, providing precise information about its position. The capacitive sensor detects the change in the capacitance as the conductive notch (109) is moved during the rotation of the rotatable interface (103), thus providing the precise information about the position of the conductive notch (109). Further, the capacitive sensor transmits the input signal to the microcontroller (115), when the determined capacitance fluctuates from a predefined threshold value indicating that conductive notch (109) is in contact with the one or more capacitive sensor.

Similarly, the inductive sensor detects the change in the inductance caused due to the rotation of the rotatable interface (103), providing precise information about the position of the notch (109). Further, the inductive sensor transmits the input signal to the microcontroller (115), when the determined inductance fluctuates from a predefined threshold value indicating that notch (109) is in contact with the one or more inductive sensor.

The inductive sensor works on the principle of electromagnetic induction, where a change in the magnetic field around a conductor induces a voltage in the conductor. This voltage is then measured by the sensor and converted into a position signal that can be used to control the movement of the machine or device. In the proposed invention, the inductive sensor is used to detect the position of the notch (109) in the rotatable interface (103). The notch (109) is a small notch or groove in the rotatable interface that is designed to interact with the inductive sensor. As the rotatable interface rotates, the notch (109) moves in and out of contact with the inductive sensor, causing a change in the inductance of the sensor. This change in inductance is then detected by the sensor and transmitted to the microcontroller (115) as an input signal. The microcontroller (115) receives the input signal from the inductive sensor and processes it to determine the precise position of the notch (109).

In an embodiment, the optical sensor detects the change in the patterns or markings on the rotatable interface (103) due to the rotation of the rotatable interface (103), providing the precise information about the position of the notch (109). The use of optical sensors in this embodiment provides a reliable and accurate means of detecting the optical path of a light emitted by LED-PD pair on the rotatable interface (103).
