As used in the specification of this application and the appended claims, the singular forms "a", "an", "the" and "the" are intended to include the plural forms as well, such as "one or more", unless the context clearly indicates otherwise. It should also be understood that in the embodiments of the present application, "one or more" means one, two, or more than two; "and/or" describes the association relationship of the associated objects, indicating that three relationships may exist; for example, a and/or B, may represent: a alone, both A and B, and B alone, where A, B may be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," or the like, in various places throughout this specification are not necessarily all referring to the same embodiment, but rather "one or more but not all embodiments" unless specifically stated otherwise. The terms "comprising," "including," "having," and variations thereof mean "including, but not limited to," unless expressly specified otherwise.

At present, the wearable equipment is provided with crowns which can realize functions of adjustment, switching and the like.

In some embodiments, as shown in FIG. 4A, test plate 303, i.e., test plate 211, has a hole 401 formed therein. The number of holes and the depth of the holes can be determined according to the functional requirements. In this embodiment, one hole may be opened every 15 °, and a total of 24 holes are uniformly arranged on the detection plate 303. In this embodiment, the outer surface of test plate 303 may be 0.5mm from the center radius of the test plate.

In other embodiments, as shown in FIG. 4B, a partial cross-sectional view of test plate 303 in the X-direction is provided. The holes 401 are arranged counterclockwise from shallow to deep, and are separately arranged. In other embodiments, the holes may not be separately provided, and may be a smooth ramp from shallow to deep. As the crown rotates, light pulses emitted by the TOF sensor are transmitted into holes of different depths or onto ramps of different depths, reflected back to be received by the TOF sensor. The TOF sensor can calculate the depth change information resulting from crown rotation and transmit the depth change information to the processor 106 for further calculations.

In some embodiments, a TOF sensor as shown in fig. 2, 3, and a detection pad as shown in fig. 2, 3, 4 are used in the wearable device 101. The light pulse that TOF sensor 302 was launched shines on detecting the dish, detects the dish and has the hole of different degree of depth, so the time that the light pulse reflects back TOF sensor 302 has the difference, so TOF sensor 302 can measure the rotatory speed of crown according to the speed that the depth information changes. The minimum speed required to cause a change in the user interface of the wearable device 101 corresponds directly to the instantaneous speed of the crown rotation, i.e. the instantaneous speed of the crown rotation is responded to by reaching a threshold user interface. The processor 106 calculates the time or phase difference of the TOF sensor emitting and receiving light pulses as depth information and derives the speed of crown rotation from the speed of the depth information over time. In some embodiments, the processor 106 of the wearable device can calculate the speed of rotation of the crown according to the following formula:

V＝Δd/Δt (1)

where Δ d is the amount of change in the depth information and Δ t is the time at which the depth information changes. If the absolute value of V is greater than the minimum speed required for a change in the user interface of wearable device 101, the user interface will change accordingly in accordance with the rotation of the crown. If the ratio of V is a positive number, the crown rotation direction is clockwise; if the ratio of V is a negative number, the rotation direction of the crown is anticlockwise; if the absolute value of V reaches a predetermined threshold value, indicating that the crown has made a complete revolution, the intersection of the minimum and maximum depths is reached, and the processor 106 may discard the value or automatically zero the value. The user interface of the touch screen of the wearable device 101 is changed accordingly according to the V value calculated by the processor 106.

In other embodiments, a TOF sensor as shown in fig. 2 and 3 and a detection pad 303 as shown in fig. 2, 3 and 4 are used in the wearable device 101. The light pulse emitted by the TOF sensor 302 irradiates the detection disc 303, holes 401 with different depths are formed in the detection disc 303, so that the time for reflecting the light pulse back to the TOF sensor 302 is different, and the rotating speed of the crown can be measured according to the speed of the change of the depth information by the TOF sensor 302. The TOF sensor 302 consists of a projector 113 and a receiver 11, which emit different light pulses depending on the projector, which can be measured in different ways. In some embodiments, a pulse modulation method may be employed to measure depth information. As shown in fig. 1C, the TOF sensor 302 includes a projector (Emitter)113, a receiver (Detector)111, a Timer (Timer)112, and the detected object 110. The TOF sensor operates by emitting a light pulse 114 from a projector 113, and then reflecting a light pulse 115 as the light pulse 114 encounters the object 110 to be detected, and the receiver 111 receives the reflected light pulse 115. The timer 112 records the time of transmission when the projector 113 transmits the light pulse 114 and the timer 112 records the time of reception when the receiver 111 receives the reflected light pulse 115. The illumination source of the pulse modulation method is generally pulse-modulated with a square wave because it is relatively easy to implement with a digital circuit.
