Embodiment Construction

[0023] The present invention will be illustrated by way of embodiments in conjunction with the drawings. In the drawings, the same reference numerals are used for the same structures, elements and parts in each figure. The dimensions and features of the components in the drawings are only for the convenience of elaboration, and do not indicate actual dimensions and proportional relationships.

[0024] figure 1 According to an embodiment of the present invention, a schematic functional framework of the virtual keyboard device 10 is shown. Understandably, figure 1 Only part of the elements in the virtual keyboard device 10 are shown in order to describe the structure and operation of the virtual keyboard device 10 according to a preferred embodiment of the present invention. For example, the virtual keyboard device 10 may also be a part of an electronic device installed, even though it may be inconvenient to carry.

[0025] In this embodiment, the device 10 includes a digital signa...

Abstract

The present invention provides a virtual keyboard apparatus. The apparatus comprises: a housing, a projection unit, an acoustic sensor, an infrared sensor, an image sensor and a digital signal processor, wherein the projection unit, the acoustic sensor, the infrared sensor and the image sensor are disposed on the housing and the digital signal processor is coupled to the acoustic sensor, the infrared sensor and the image sensor. The projection unit projects a virtual keyboard onto a plane. When a user touches a key in the virtual keyboard, the digital signal processor determines a clicked state of the virtual keyboard according to digital signals generated by the acoustic sensor, the infrared sensor and the image sensor. The virtual keyboard apparatus is extremely low in false touch rate, diverse in function, reasonable in structure, and portable.

Description

Technical field [0001] The invention relates to an electronic device, in particular to a virtual keyboard device and a control method thereof. Background technique [0002] With the development of electronic control technology, data or instruction input devices are used in more and more fields. Generally speaking, people have been pursuing a keyboard input device that is easy to carry, and hope that the keyboard device can perform accurate and quick input to meet the increasing demand for instructions. [0003] In the prior art, technicians use virtual keyboard technology to achieve their goals. The virtual keyboard is a projection technology that projects the keyboard pattern on the desktop. The user taps his finger on the keyboard pattern. The camera captures the position of the user's finger, determines the button clicked by the user, and then inputs the data or instructions that the user wants to input. [0004] The virtual keyboard device often has a larger false touch rate ...
