Embodiment 1

[0028] figure 1 and figure 2 A miniature projection computer showing an embodiment of the present invention includes: a computer module 101, a projection keyboard module 102 and a projection screen module 103;

[0029] The computer module 101 is used to run computer systems and application programs;

[0030] The projection keyboard module 102 projects a virtual keyboard 104 on a horizontal plane around the miniature projection computer, and simultaneously converts the user's operation gestures on the virtual keyboard 104 into input instructions and sends them to the computer module 101; A consistent surface, such as a tabletop.

[0031] The projection screen module 103 projects the display signal of the computer module 101 on a vertical plane around the micro-projection computer as the screen 105 of the micro-projection computer, and simultaneously captures the user's page-turning gesture operation, and sends the page-turning instruction to the computer module 101. The ab...

Embodiment 2

[0035] This embodiment is basically the same as Embodiment 1, and the difference is that the projection keyboard module 102, in this embodiment, the projection keyboard module 102 includes a keyboard projection unit 201, a keyboard image acquisition unit 202, a first processing unit 204 and an inline infrared ray emission Unit 203; the inline infrared emitting unit 203 emits the inline infrared parallel to the keyboard, and the keyboard image acquisition unit 202 is covered with an infrared bandpass filter, and the infrared bandpass filter is only limited to the inline infrared wavelength The same infrared rays pass through, and the keyboard image acquisition unit 202 only collects infrared images. The infrared band-pass filter can filter out light of other wavelengths, thereby avoiding interference information of other images and reducing the calculation amount of the first processing unit.

Embodiment 3

[0037] This embodiment is an embodiment of gesture page turning operation. combine figure 1 , figure 2 and image 3 The method for using gestures to control the micro-projection computer to turn pages in an embodiment is described:

[0038] Step 1, the depth image acquisition unit 206 acquires a depth image, and sends the depth image to the second processing unit 209, and the infrared image acquisition unit 207 acquires an infrared image, and sends the infrared image to the second processing unit 209;

[0039] Step 2: After receiving the depth image and the infrared image, the second processing unit 209 combines the above two images, obtains the geometric center of the palm making the page-turning gesture through image morphology operations, and tracks the position of the geometric center to obtain motion features value;

[0040] Step 3. Identify the waving direction of the palm through the motion feature value. For example, if the waving direction is facing the left dire...

Abstract

The invention discloses a micro projection computer and a method for controlling the micro projection computer to perform page turning by utilizing a gesture. The micro projection computer comprises a computer module, a projection keyboard module and a projection screen module, wherein the computer module is used for running a computer system and an application; the projection keyboard module projects a virtual keyboard on a horizontal plane around the micro projection computer, converts an operation gesture of a user on the virtual keyboard into an input instruction, and sends the input instruction to the computer module; and the projection screen module projects a display signal of the computer module to a vertical plane around the micro projection computer, captures a page turning gesture operation of the user, and sends a page turning instruction to the computer module. The computer volume is reduced by replacing a conventional physical keyboard with a projection keyboard, so that the computer is more convenient to carry; and direct projection of a computer screen is realized through the screen projection module instead of an external projection device, so that the computer is more adaptive to the variety and complexity of occasions of office, training and the like.

Description

technical field [0001] The invention belongs to the technical field of intelligent mobile devices, and in particular relates to a micro-projection computer and a method for controlling the page-turning of the micro-projection computer by gestures. Background technique [0002] A projector, also known as a projector, is a device that can project images or videos onto a screen. Education, business, government, and home entertainment are the four major consumer groups that support the projector industry. Judging from the future development form of the industry, education is still the pillar area for the future development of the industry. In 2010, there were 129,100 kindergartens, 394,200 primary schools, 79,000 ordinary middle schools, 3,047 ordinary secondary schools, and 1,778 higher education schools nationwide. According to the calculation of each classroom equipped with a projector, according to relevant data, China only The market capacity of the education industry is m...
