Apple has submitted a document to the US Patent and Trademark Office regarding wearable electronic ring computing devices. According to the description, electronic link devices can be worn on fingers, which can serve as input peripherals for other devices as well as a miniature version of the Apple Watch. Ring computing devices have built-in processors, wireless transceivers, power supplies, and microphones. Apple also wants to implant other sensors into the device so that the ring can detect and interpret gestures. The ring also has a dial controller, which is equivalent to Apple Watch's Digital Crown.

There are multiple tactile actuators inside the ring that can provide force feedback and transmit directional tokens to the user; There is an internal motion sensor that can sense writing movements; There are biosensors that can track health data to ensure safety; In addition, the bracelet also supports NFC communication. Through wireless connection, the ring can transmit identity information to a second device and then unlock the Mac.

The ring supports multiple gestures. For example, when we point our finger wearing a ring towards another independent device, a wireless connection message will pop up; Sliding or flicking can change menu options; We can also rotate our fingers or devices; The device will vibrate when touched or lightly tapped on the surface.

Due to the presence of multiple transmitters inside the ring, it can share the rotation angle with other devices, allowing them to determine the specific position of each transmitter in 3D space. The bracelet is equipped with a touch screen that allows for character input, similar to the Apple Watch. (The above content comes from: IT Home, please indicate when reprinted)

Amazon has launched the Smart Ring Echo Loop, which has two built-in microphones that can be activated with buttons and supports tactile feedback; Echo Loop can also be connected to the Alexa app on the phone through Bluetooth.
