Problems solved by technology

The first is to use a special projection-screen device. Although this method is more intuitive, it is not friendly to the people and cannot guarantee universality and portability; the second is to synchronize the electronic device with a host connected to the projection device. This method is more convenient to operate, but the demonstrator is still only operating the electronic device, not the projection surface. It is not direct and intuitive enough for the viewer and the demonstrator. There is still a gap between the demonstrator's expressive intention and his behavior a huge ravine

Embodiment 1

[0051] A control method provided by an embodiment of the present invention is applied to a first electronic device, wherein the first electronic device is connected to a second electronic device and a third electronic device, and the second electronic device has a collection unit, The third electronic device has a projection display unit, such as figure 1 As shown, the control method mainly includes the following steps:

[0052] Step 101: Receive a first instruction, wherein the first instruction is used to control the first electronic device to use a first acquisition mode;

[0053] Since the method is applied to the first electronic device, the subject of execution of step 101 is the first electronic device, then, step 101 can also be described as: the first electronic device receives the first instruction, wherein the first instruction It is used for controlling the first electronic device to use the first acquisition mode.

[0054] Here, the first collection mode is a mo...

Embodiment 2

[0075] The embodiment of the present invention also provides another control method, which is applied to a first electronic device, wherein the first electronic device is connected to a second electronic device and a third electronic device, and the second electronic device has a collection unit , the third electronic device has a projection display unit, such as figure 2 As shown, the control method mainly includes the following steps:

[0076] Step 201: When it is determined that the first instruction has not been received, generate a third instruction, wherein the third instruction is used to control the first electronic device to use the second acquisition mode;

[0077] Here, the second collection mode is a mode for collecting simple gestures. The second acquisition mode can be understood as a mode that does not require precise positioning, that is, a default acquisition mode in the first electronic device.

[0078] Since this method is applied to the first electronic ...

Embodiment 3

[0091] The coordinate conversion method provided by the embodiment of the present invention is applied to a first electronic device, wherein the first electronic device is connected to a second electronic device and a third electronic device, the second electronic device has a collection unit, and the The third electronic device has a projection display unit. like image 3 as shown, image 3 For the schematic diagram of coordinate transformation, in image 3 There are four calibration points in .

[0092] Specifically, performing coordinate transformation mainly includes the following steps:

[0093] Step 301: Determine the calibration point;

[0094] Here, when determining the calibration points, at least three or more different calibration points are determined.

[0095] Specifically, the calibration point can be determined through a simple initialization scheme in the prior art, for example, calibration according to the position difference. Alternatively, the calibrat...

Abstract

The present invention discloses electronic equipment and a control method which is applied to first electronic equipment, wherein the first electronic equipment is connected with second electronic equipment and third electronic equipment; the second electronic equipment has a collection unit; and the third electronic equipment has a projection display unit. The method comprises: receiving a first command, wherein the first command is used for controlling the first electronic equipment to use a first collection mode; sending a second command to the projection display unit of the third electronic equipment and controlling the projection display unit for performing the projection display of a first image; and based on the first collection mode, controlling the collection unit in the second electronic equipment for collecting gestures before the first image according to the first mode. By means of the present invention, the operation on a projection plane can be realized, thereby improving user experience.

Description

technical field [0001] The invention relates to the technical field of control, in particular to an electronic device and a control method. Background technique [0002] At present, presentations using projection equipment (such as projectors) have been widely used in daily work and life. However, the inability to operate on a projection surface, such as a screen, is somewhat inconvenient. In view of the above problems, the current main solutions are roughly divided into two types. The first is to use a special projection-screen device. Although this method is more intuitive, it is not friendly to the people and cannot guarantee universality and portability; the second is to synchronize the electronic device with a host connected to the projection device. This method is more convenient to operate, but the demonstrator is still only operating the electronic device, not the projection surface. It is not direct and intuitive enough for the viewer and the demonstrator. There i...
