Information input method for wearable device and wearable device

Abstract

The invention provides an information input method for a wearable device and the wearable device. The wearable device is provided with a processor and a camera. The processor controls the camera to display a virtual keyboard in a corresponding display region; the virtual keyboard is overlapped on a preview picture of the display region, and the virtual keyboard is semi-transparent and is fixed relative to the preview picture; the camera collects action information of fingers of a user in real time; the processor detects the action information of the fingers of the user in each frame picture collected by the camera and determines all characters input by the fingers of the user on the virtual keyboard; the processor conducts information input according to all the determined characters. Character information input can be carried out by mounting the camera on the wearable device without arranging an additional device and relying on other devices, and the requirements of the user for inputting character information at any time can be met; moreover, the wearable device is simple in structure and convenient to carry and quite convenient to use.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an information input method of a wearable device and the wearable device. Background technique [0002] In recent years, with the rapid development of electronic technology, wearable devices such as smart watches, health bracelets and smart glasses have been used by more and more people, connecting people and the Internet more closely, giving people life and perception brought about huge changes. Wearable device means that it can be worn directly on on the body , or a portable device that is integrated into the user's clothing or accessory. Wearable devices are not just a hardware device, but also through software Support and data interaction, cloud interaction to achieve powerful functions, which will bring great changes to people's lives. [0003] In the prior art, for the input of character information, touch devices such as smartphones and tablet computers are equip...

Problems solved by technology

[0004] However, in the process of implementing the present invention, the inventor found that the prior art has at least the following disadvantages: Although the current prior art can realize the input of character information on the wearable device, the input of character information by an external physical keyboard will lead to portability. The device is no longer portable, and it is inconvenient to input anytime and anywhere

Using a laser projection keyboard for character information input requires installing a laser projector on the wearable d...
