Electronic device with virtual input function

Abstract

The invention provides an electronic device, which comprises a screen, an image extraction unit, a storage unit and a processing unit, wherein the image extraction unit is arranged on the back side of the electronic device; the processing unit is coupled with the screen, the image extraction unit and the storage unit; the storage unit records a plurality of modules; and the processing unit accesses and executes the modules for performing the following steps of: displaying a user interface onto the screen; integrating the user interface and a hand image extracted by the image extraction unit to generate a plurality of integration images, and displaying the integration images on the screen; recognizing the gesture of a user according to the hand image, and obtaining the position, relative to the user interface, of the gesture to generate a plurality of detection positions; and generating input signals corresponding to the gesture according to the detection position on the user interface so as to operate the user interface.

Description

technical field [0001] The invention relates to an electronic device, and in particular to an electronic device with a virtual input function. Background technique [0002] With the development of technology, more complex and more user-friendly electronic products have been introduced. For example, laptop computers, tablet computers, and smart phones already have the same functions as desktop computers, plus features such as small size and light weight, Allowing users to carry it with them has become an indispensable and important tool in the life and work of ordinary people. [0003] However, currently, when a user uses an electronic device such as a smart phone or a tablet computer without a physical keyboard and a mouse, the user can handwrite or operate a virtual keyboard displayed on the screen for document processing, which is relatively inconvenient. However, if it is matched with a physical keyboard and mouse, the carrying volume and weight will be increased, and t...
