The 5-way key 3 is positioned in the middle of the ring body 1, and correspondingly, the key cap 32 is positioned in the middle of the ring body 1. When the finger ring is worn, the finger ring body 1 can be sleeved on the index finger, and the key cap 32 faces the direction of the thumb. The MCU main control module is used for judging the wearing direction of the ring body 1 according to the sensing signals transmitted by the sensing module, and correcting the key values of the keys 3 transmitted from the 5-direction key according to the judgment result to generate a corresponding control instruction.

The 5-way key 3 includes a rocker 31 (the rocker 31 is shifted in 4 directions up, down, left, and right and pressed down) which can generate 5 pressing results, that is, the 5-way key 3 has 5 key values in the middle of up, down, left, right, and left. The top surface of the ring body 1 is provided with a through hole for the rocker 31 to penetrate through, and the key cap 32 is directly arranged at one end part of the rocker 31 extending out of the through hole; the key cap 32 is mushroom shaped.

Besides the above functional modules, the PCB 2 is also integrated with other functional modules that implement control functions, such as a power module and a wireless communication module, which are disclosed in the prior art and therefore not described herein again.

In this embodiment, the MCU main control module includes a determination unit configured to determine a wearing direction of the ring body 1 according to the sensing signal transmitted by the sensing module, and a key value correction unit configured to correct the key value transmitted from the 5-way key 3 according to a determination result transmitted by the determination unit. The judging unit and the key value correcting unit can be a processing chip integrating corresponding functions and can also be provided by the MCU main control module. Whether such functionality is implemented as hardware or software depends upon the particular application and design constraints imposed on the implementation.

There are many sensing modules that can sense finger contact or proximity, such as:

When the mobile phone is worn in the forward direction, the key value correction unit does not correct the key value transmitted from the 5-direction key 3, and uploads the key value according to the key value calibrated in the forward direction to generate a corresponding control instruction; when the mobile phone is worn reversely, the key value correction unit corrects the key value transmitted to the key 3 by the key value correction unit 5, namely, the upper key value and the lower key value are interchanged, the left key value and the right key value are interchanged, and the corrected key value is uploaded to generate a corresponding control instruction.

For example, when the user wants to perform the operation of moving upward by pressing the key, the user can perform the operation of moving upward by pressing the upward offset key of the 5-way key 3 regardless of wearing in the forward direction or in the reverse direction. In short, no matter how the user wears the electronic device, the user can operate the 5-direction key according to a conventional operation method to achieve the purpose of operation; namely, the MCU main control module can identify the same action command for the key operation in the same direction when the MCU main control module is worn in different directions.
